Dr. Diane Poole Heller - Four Attachment Styles


In this video Dr. Diane Poole Heller goes through the four attachment styles and gives examples of each. Our attachment style is set by the time we are three years old (give or take) and barring any effort to change it remains fairly constant throughout the lifespan, shaping all of our relationships.

Four Attachment Styles


This is a pretty basic introduction, but it's solid information (even though my own sense of these styles is a little different from hers). Dr. Heller is the founder of Somatic Attachment Training & Experience (SATe), a series of groundbreaking somatic adult attachment workshops for therapists.

Measuring Nurture: Study Shows How 'Good Mothering' Hardwires Infant Brain


The study summarized below was conducted on rats, but parent-child bonding at the physiological level is pretty much the same in all mammals - so this does translate well to humans.

The study found that the presence and nurturing behaviors of the mother (or father, or primary care-giver) toward the newborn directly shapes the wiring and function of the infant's brain. This is the first study to show this process (which is well-known) WHILE it is happening.

Pretty cool. The paper itself, of course, is behind a paywall, so below is the summary from Science Daily, followed by the abstract of the original article.

Measuring nurture: Study shows how 'good mothering' hardwires infant brain

Summary:
By carefully watching nearly a hundred hours of video showing mother rats protecting, warming, and feeding their young pups, and then matching up what they saw to real-time electrical readings from the pups’ brains, researchers have found that the mother’s presence and social interactions — her nurturing role — directly molds the early neural activity and growth of her offsprings’ brain.

By carefully watching nearly a hundred hours of video showing mother rats protecting, warming, and feeding their young pups, and then matching up what they saw to real-time electrical readings from the pups' brains, researchers at NYU Langone Medical Center have found that the mother's presence and social interactions -- her nurturing role -- directly molds the early neural activity and growth of her offsprings' brain.

Reporting in the July 21 edition of the journal Current Biology, the NYU Langone team showed that the mother's presence in the nest regulated and controlled electrical signaling in the infant pup's brain.

Although scientists have known for decades that maternal-infant bonding affects neural development, the NYU Langone team's latest findings are believed to be the first to show -- as it is happening -- how such natural, early maternal attachment behaviors, including nesting, nursing, and grooming of pups, impact key stages in postnatal brain development.

Researchers say the so-called slow-wave, neural signaling patterns seen during the initial phases of mammalian brain development -- between age 12 and 20 days in rats -- closely resembled the electrical patterns seen in humans for meditation and conscious and unconscious sleep-wake cycles, and during highly focused attention. These early stages are when permanent neural communication pathways are known to form in the infant brain, and when increasing numbers of nerve axons become sheathed, or myelinated, to speed neural signaling.

According to senior study investigator and neurobiologist Regina Sullivan, PhD, whose previous research in animals showed how maternal interactions influenced gene activity in the infant brain, the latest study offers an even more profound perspective on maternal caregiving.

"Our research shows how in mammals the mother's sensory stimulation helps sculpt and mold the infant's growing brain and helps define the role played by 'nurturing' in healthy brain development, and offers overall greater insight into what constitutes good mothering," says Sullivan, a professor at the NYU School of Medicine and its affiliated Nathan S. Kline Institute for Psychiatric Research. "The study also helps explain how differences in the way mothers nurture their young could account, in part, for the wide variation in infant behavior among animals, including people, with similar backgrounds, or in uniform, tightly knit cultures."

"There are so many factors that go into rearing children," says lead study investigator Emma Sarro, PhD, a postdoctoral research fellow at NYU Langone. "Our findings will help scientists and clinicians better understand the whole-brain implications of quality interactions and bonding between mothers and infants so closely after birth, and how these biological attachment behaviors frame the brain's hard wiring."

For the study, a half-dozen rat mothers and their litters, of usually a dozen pups, were watched and videotaped from infancy for preset times during the day as they naturally developed. One pup from each litter was outfitted with a miniature wireless transmitter, invisibly placed under the skin and next to the brain to record its electrical patterns.

Specifically, study results showed that when rat mothers left their pups alone in the nest, infant cortical brain electrical activity, measured as local field potentials, jumped 50 percent to 100 percent, and brain wave patterns became more erratic, or desynchronous. Researchers point out that such periodic desynchronization is key to healthy brain growth and communication across different brain regions.

During nursing, infant rat pups calmed down after attaching themselves to their mother's nipple. Brain activity also slowed and became more synchronous, with clearly identifiable electrical patterns.

Slow-wave infant brain activity increased by 30 percent, while readings of higher brain-wave frequencies decreased by 30 percent. Milk delivery led to intermittent bursts of electrical brain activity that were double or five times higher than before.

Similar spikes in rat brain activity of more than 100 percent were observed when mothers naturally groomed their infant pups.

However, these brain surges progressively declined during weaning, as infant pups gained independence from their mothers, leaving the nest and seeking food on their own as they grew past two weeks of age.

Additional experiments with a neural-signaling blocking agent, propranolol, confirmed that maternal effects were controlled in part by secretion of norepinephrine, a key neurotransmitter and hormone involved in most basic brain and body functions, including regulation of heart rate and cognition. Noradrenergic blocking in infant rats mostly dampened all previously observed effects induced by their mothers.

Sullivan says her team next plans similar experiments to look at how behavioral variations by the mother affect infant rat brain development, with the added goal of mapping any differences in brain development.

Long term, they say, they hope to develop diagnostic tools and therapies for people whose brains may have been impaired or simply underdeveloped during infancy.

Sarro says more research is also under way to investigate what other, nonadrenergic biological mechanisms might also be involved in controlling maternal sensory stimulation of the infant brain.

Highlights

  • The mother’s presence reduces infant rat cortical desynchronization
  • Maternal behaviors (e.g., milk ejection and grooming) increase desynchronization
  • Maternal effects on infant cortical activity decline with age
  • Norepinephrine receptor blockade reduces impact of dam on infant cortical activity
Summary

Patterns of neural activity are critical for sculpting the immature brain, and disrupting this activity is believed to underlie neurodevelopmental disorders [ 1–3 ]. Neural circuits undergo extensive activity-dependent postnatal structural and functional changes [ 4–6 ]. The different forms of neural plasticity [ 7–9 ] underlying these changes have been linked to specific patterns of spatiotemporal activity. Since maternal behavior is the mammalian infant’s major source of sensory-driven environmental stimulation and the quality of this care can dramatically affect neurobehavioral development [ 10 ], we explored, for the first time, whether infant cortical activity is influenced directly by interactions with the mother within the natural nest environment. We recorded spontaneous neocortical local field potentials in freely behaving infant rats during natural interactions with their mother on postnatal days ∼12–19. We showed that maternal absence from the nest increased cortical desynchrony. Further isolating the pup by removing littermates induced further desynchronization. The mother’s return to the nest reduced this desynchrony, and nipple attachment induced a further reduction but increased slow-wave activity. However, maternal simulation of pups (e.g., grooming and milk ejection) consistently produced rapid, transient cortical desynchrony. The magnitude of these maternal effects decreased with age. Finally, systemic blockade of noradrenergic beta receptors led to reduced maternal regulation of infant cortical activity. Our results demonstrate that during early development, mother-infant interactions can immediately affect infant brain activity, in part via a noradrenergic mechanism, suggesting a powerful influence of the maternal behavior and presence on circuit development.

Kissing Helps Us Find the Right Partner – And Keep Them


Kissing is a nearly universal trait in human cultures, but scientists have never been clear on why it is so prevalent and what role(s) it serves. A new study by Oxford University researchers (published in two separate papers, Archives of Sexual Behavior and Human Nature) suggests that kissing helps us size up potential partners and, when we are in a relationship, kissing may also be the glue that persuades a partner to stay.

While I am not convinced this study fully explains the complexity of kissing as a feature of human relationships, one of the more interesting results from this research is that frequency of kissing is a better indicator of relationship health than is frequency of sex.

Kissing Helps Us Find the Right Partner – And Keep Them


Oct. 10, 2013 — What's in a kiss? A study by Oxford University researchers suggests kissing helps us size up potential partners and, once in a relationship, may be a way of getting a partner to stick around.


"Kissing in human sexual relationships is incredibly prevalent in various forms across just about every society and culture," says Rafael Wlodarski, the DPhil student who carried out the research in the Department of Experimental Psychology at Oxford University. "Kissing is seen in our closest primate relatives, chimps and bonobos, but it is much less intense and less commonly used.

"So here's a human courtship behavior which is incredibly widespread and common and, in extent, is quite unique. And we are still not exactly sure why it is so widespread or what purpose it serves."

To understand more, Rafael Wlodarski and Professor Robin Dunbar set up an online questionnaire in which over 900 adults answered questions about the importance of kissing in both short-term and long-term relationships.

Rafael Wlodarski explains: "There are three main theories about the role that kissing plays in sexual relationships: that it somehow helps assess the genetic quality of potential mates; that it is used to increase arousal (to initiate sex for example); and that it is useful in keeping relationships together. We wanted to see which of these theories held up under closer scrutiny."

The researchers report their findings in two papers, one in the journal Archives of Sexual Behavior and the second in the journal Human Nature, both published by Springer. They were funded by the European Research Council.

The survey responses showed that women rated kissing as generally more important in relationships than men. Furthermore, men and women who rated themselves as being attractive, or who tended to have more short-term relationships and casual encounters, also rated kissing as being more important.

In humans, as in all mammals, females must invest more time than men in having offspring - pregnancy takes nine months and breast-feeding may take up to several years. Previous studies have shown women tend to be more selective when initially choosing a partner. Men and women who are more attractive, or have more casual sex partners, have also been found to be more selective in choosing potential mates. As it is these groups which tended to value kissing more in their survey responses, it suggests that kissing helps in assessing potential mates.

It has been suggested previously that kissing may allow people to subconsciously assess a potential partner through taste or smell, picking up on biological cues for compatibility, genetic fitness or general health.

"Mate choice and courtship in humans is complex," says Professor Robin Dunbar. "It involves a series of periods of assessments where people ask themselves 'shall I carry on deeper into this relationship?' Initial attraction may include facial, body and social cues. Then assessments become more and more intimate as we go deeper into the courtship stages, and this is where kissing comes in."

He adds: "In choosing partners, we have to deal with the 'Jane Austen problem': How long do you wait for Mr Darcy to come along when you can't wait forever and there may be lots of women waiting just for him? At what point do you have to compromise for the curate?

"What Jane Austen realised is that people are extremely good at assessing where they are in the 'mating market' and pitch their demands accordingly. It depends what kind of poker hand you've been dealt. If you have a strong bidding hand, you can afford to be much more demanding and choosy when it comes to prospective mates.

"We see some of that coming out in the results of our survey, suggesting that kissing plays a role in assessing a potential partner," Professor Dunbar explains.

Past research has also found that women place greater value on activities that strengthen long-term relationships (since raising offspring is made easier with two parents present). In the current study, the team found that kissing's importance changed for people according to whether it was being done in long-term or short-term relationships. Particularly, it was rated by women as more important in long-term relationships, suggesting that kissing also plays an important role in mediating affection and attachment among established couples.

While high levels of arousal might be a consequence of kissing (particularly as a prelude to sex), the researchers say it does not appear to be a driving factor that explains why we kiss in romantic relationships.

Other findings included:
  • In short relationships, survey participants said kissing was most important before sex, less so during sex, was less important again after sex and was least important at other times. In committed relationships, where forming and maintain a lasting bond is an important goal, kissing was equally important before sex and at times not-related to sex.    
  • More frequent kissing in a relationship was linked to the quality of a relationship, while this wasn't the case for having more sex. However, people's satisfaction with the amount of both kissing and sex did tally with the quality of that relationship. 
  • In a companion paper in the journal Human Nature, the researchers report that women's attitudes to romantic kissing also depend on where in their menstrual cycle and their relationship they are. Women valued kissing most at initial stages of a relationship when they were in the part of their cycle when they are most likely to conceive. Previous studies have shown that hormonal changes associated with the menstrual cycle can change a woman's preferences for a potential mate. When chances of conceiving are highest, women seem to prefer men who display supposed signals of underlying genetic fitness, such as masculinized faces, facial symmetry, social dominance, and genetic compatibility. It appears that kissing a romantic potential partner at this time helps women assess the genetic quality of a potential mate, the researchers say.

Authors@Google - Paul Zak on "The Moral Molecule"


Paul Zak is a name that turns up quite a bit in Julian Baggini's The Ego Trick - and now he has a new book out that is getting some good attention, The Moral Molecule: The Source of Love and Prosperity. Zak is a proponent of the oxytocin theory of human bonding and happiness.

If you pay close attention to the shot of the book cover at the beginning of the talk, you'll notice the different subtitle for the British version, The New Science of What Makes Us Good or Evil. Interesting, that - even his website (he's a Brit) now has the revised cover shot.

Anyway, if interested, his website has a lot of additional resources to explore.




Authors@Google - Paul Zak on "The Moral Molecule"

Filmed live from Google London on Thursday 31st May, 2012.

Paul Zak is the founding Director of the Centre for Neuroeconomics Studies and Professor of Economics at Claremont Graduate University. He is the proponent of the theory that oxytocin, a hormone generally associated with childbirth and present in all of us, drives our morality and is responsible for trust, empathy and other feelings that build and help maintain stable societies.

In his new book, Zak sets out to ask why are men less faithful than women? Why are some people altruists and others cold-hearted bastards? Why do some businesses succeed while others collapse?

Website: www.themoralmolecule.com

Zak offers some suggestions to help you raise your oxytocin levels at his website:
Oxytocin isn't just for giving birth and breastfeeding. As I discuss in The Moral Molecule, my research has discovered many activities that cause people's brains to release oxytocin--even the brains of complete strangers. But here's the key: oxytocin is the brain's love chemical and just like love, you have to give it to get it. By that I mean, you can do things that will cause someone else's brain to release oxytocin, but you can't do this selfishly. Give freely to others and when their brains release oxytocin they will want to reciprocate and give back to you.

Here are some of my favorite ways to cause oxytocin release in others. If you've found an activity you think releases oxytocin, add it to the list!
Give someone a hug
• Introduce yourself to someone new
• Make someone smile by being silly
• Share a meal
• Dance
• Make music with someone
• Join a choir
• Kiss
• Give someone a massage
• Go to the movies
• Ride a roller coaster
• Soak in a hot tub with a friend
• Surprise someone with a gift
• Pet a dog
• Use social media to connect to others
• Take a hike with a friend
• Write a note of thanks to a teacher or mentor
• Forgive someone who has wronged you
• Meditate or pray for 10 minutes focusing on compassion

The Wright Show - Robert Wright and Paul J. Zak - The Moral Molecule


This week's episode of The Wright Show features your host, Robert Wright, in a discussion with Paul Zak about his new book, The Moral Molecule: The Source of Love and Prosperity. There's been a lot of hype around oxytocin, some of it valid (infant/mother bonding, and it seems to be useful in improving social skills with autistic children) and some of it seems to be just hype (so far, there seems to be no method of administration that allows oxytocin to cross the blood-brain barrier, so any endogenous administration is questionable at best).

PAUL J. ZAK, Ph.D., is professor of economic psychology and management at Claremont Graduate University. As the founding director of Claremont's Center for Neuroeconomics Studies, he is at the vanguard of neuroeconomics, a new discipline that integrates neuroscience and economics. He has a popular Pyschology Today blog called The Moral Molecule. He makes numerous media appearances, and his research has been featured in The New York Times, The Wall Street Journal, USA Today, Scientific American, Fast Company, and many others.

From Wikipedia:
Zak's research aims to challenge the thought that people generally are driven primarily to act for what they consider their self-interest[4], and asks how morality may modulate ones interpretation of what constitutes "self-interest" in ones own personal terms.[5] Methodological questions have arisen in regards to Zak's work, however.[6] Other commentators though have called his work "one of the most revealing experiments in the history of economics." [7]
Zak spoke at TED in 2011 - Trust, morality - and oxytocin
Where does morality come from -- physically, in the brain? In this talk neuroeconomist Paul Zak shows why he believes oxytocin (he calls it "the moral molecule") is responsible for trust, empathy, and other feelings that help build a stable society.



With that background, here is the Bloggingheads episode from this week.

Dan Siegel - Mindsight: The New Science of Personal Transformation

I'm sure I posted this once before when it was new, but Dan Siegel is bringing attachment theory into personal practice for all of us, rather than having it be something that only applies to children and parenting.

This video comes from the Google Tech Talks series on personal growth, and his talk is based on the book of the same name, Mindsight.

Mindsight: The New Science of Personal Transformation

ABSTRACT

This interactive talk will examine two major questions: What is the mind? and How can we create a healthy mind? We'll examine the interactions among the mind, the brain, and human relationships and explore ways to create a healthy mind, an integrated brain, and mindful, empathic relationships. Here is one surprising finding: the vast majority (about 95%) of mental health practitioners around the globe, and even many scientists and philosophers focusing on the mind, do not have a definition of what the mind is! In this talk, well offer a working definition of the mind and practical implications for how to perceive and strengthen the mind itself—a learnable skill called mindsight. Then well build on this perspective to explore ways that the mind, the brain, and our relationships are influenced by digital information flow and also how they can be moved toward healthy functioning.


Allan Schore - Human Nature and Early Experience & "The Neurobiology of a Secure Attachment"

Allan Schore is the leading figure in the neurobiology of attachment and the neuroscience of affect regulation. He, along with Dan Siegel and some others, co-founded the field of interpersonal neurobiology.

I'm am thrilled to have found a full-length lecture from him for attachment theory day here at IOC. However, my experience of him is that he is brilliant, but his talks are dry.

His major books are Affect Regulation and the Origin of the Self: The Neurobiology of Emotional Development, Affect Dysregulation and Disorders of the Self/Affect Regulation and the Repair of the Self (two-volume set), and his new book, The Science of the Art of Psychotherapy, which I just received today and look forward to reading.

First up a short video on neuroscience and secure attachment.

Paul J. Zak - Love, Belief, and Neurobiology of Attachment

Alrighty then . . . . Sorry for the long delay, but I had to go to work. So, now I'm back, and here is the next installment in attachment theory day, from a post by Research Channel.

Love, Belief, and Neurobiology of Attachment


In this Loma Linda video, Paul J. Zak, founding director of the Center for Neuroeconomics Studies at Claremont Graduate University, gives a scientific twist on the topics of attachment and trust. By looking into the geographical and biological aspects of human trust, Zak presents an engaging conversation into how trust affects our behaviors, from our social interactions with strangers to peoples relationships with God and religion.


Contextualizing Attachment Theory and Practice & Understanding Great Leadership Using the Filter of Secure Attachment

It's attachment theory day at IOC. Just because. Both of these videos were offered by Genetic Alliance as a two-part webinar on attachment theory and practice.

There will be more to come later today.

Contextualizing Attachment Theory and Practice



This program is the first of two webinars focusing on attachment theory and practice. It will give an overview with special attention to the potential uses of attachment theory for parents and family members in the advocacy community. Annmarie Early's experience as a professor and couples' therapist combines theory and practice with numerous stories of the application of attachment theory.




Understanding Great Leadership Using the Filter of Secure Attachment


This program, the second of two on attachment theory and practice, will focus on the Genetic Alliance leadership model developed over the last eight years with specific attention to attachment theory. Organizational transformation begins with ourselves as leaders and the energy, creativity, and productivity of our organization is a direct function of our leadership. Attachment theory gives a simple, clear, and direct framework for understanding the value of a leader's accessibility, responsiveness, and emotional engagement—all essential expressions of a secure attachment identity.

Research: Oxytocin and mutual communication in mother-infant bonding


Attachment theory has become one of the dominant models for understanding the etiology of mental illness. More and more, we are finding that the caregiver-infant bond is crucial in the later mental health of the child. There are many factors that influence this bonding, including the attachment wounds of the caregiver, environment, genetics, and a host of other factors, including the biology of child and caregiver.

One of the primary biological factors (which also is determined by many other variables) is oxytocin. This new study looks at the role of oxytocin in bonding, which we know to be crucial while not yet understanding the mechanisms involved.

The article is open access, from Frontiers in Human Neuroscience.

Oxytocin and mutual communication in mother-infant bonding

Mother-infant bonding is universal to all mammalian species. In this review, we describe the manner in which reciprocal communication between the mother and infant leads to mother-infant bonding in rodents. In rats and mice, mother-infant bond formation is reinforced by various social stimuli, such as tactile stimuli and ultrasonic vocalizations (USVs) from the pups to the mother, and feeding and tactile stimulation from the mother to the pups. Some evidence suggests that mother and infant can develop a cross-modal sensory recognition of their counterpart during this bonding process. Neurochemically, oxytocin in the neural system plays a pivotal role in each side of the mother-infant bonding process, although the mechanisms underlying bond formation in the brains of infants has not yet been clarified. Impairment of mother-infant bonding, that is, deprivation of social stimuli from the mother, strongly influences offspring sociality, including maternal behavior toward their own offspring in their adulthood, implying a “non-genomic transmission of maternal environment,” even in rodents. The comparative understanding of cognitive functions between mother and infants, and the biological mechanisms involved in mother-infant bonding may help us understand psychiatric disorders associated with mother-infant relationships.

I am including the introduction to entice you to go read the whole article.

Introduction

“Sympathy is much strengthened by habit. In however complex a manner this feeling may have originated, as it is one of high importance to all those animals which aid and defend one another, it will have been increased through natural selection; for those communities, which included the greatest number of the most sympathetic members, would flourish best, and rear the greatest number of offspring” (Charles Darwin, “Descent of Man,” 1871).

During the process of mammalian evolution, animals developed sympathetic neural and behavioral systems, in which for example, weak and helpless member of individuals are protected and nurtured by other group members. This phenomenon is mostly clearly observed in mother-infant relationship, such as mother infant bonding (Broad et al., 2006).

Social bonds like mother-infant bonding are hypothetical constructs and cannot be measured directly. However, there are several behavioral and physiological measures that have been used as indices of social bonding, including increased physical proximity (Hennessy, 1997), behavioral distress, or elevated corticosteroid levels following separation from the bonding partner (Ziegler et al., 1995; Norcross and Newman, 1999). Social bonding has not yet been clearly defined, but it has been proposed that social bonding can be distinguished neurochemically from social affiliation, in which corticosteroid elevation does not occur following separation (DeVries, 2002). Moreover, subsequent reunion with conspecific animals ameliorates separation distress or aversive experiences. This phenomenon is termed as “social buffering” (Kikusui et al., 2006); its effect depends on the degree of affiliation with the partner and is strongest with the bonding partner, such as that seen in the dyad of mother-infant.

Mother-infant bonding is unique with respect to its influence on the offspring's future. This idea was first suggested in humans by Bowlby's attachment theory (Bowlby, 1969). Subsequently, many psychological and animal research studies have reported that child abuse or childhood neglect are correlated with severe, deleterious long-term effects on the child's cognitive, socio-emotional, and behavioral development (Hildyard and Wolfe, 2002). The developmental effects of mother-infant bonding have also been indicated experimentally in non-human primates. For example, in a study by Winslow et al. (2003), mother-reared and human nursery-reared monkeys were subjected to a novel environment with or without a cage mate. The monkeys reared by their mothers exhibited a reduced cortisol response when a social partner was available, whereas nursery-reared monkeys did not. In nursery-reared monkeys, social contact, such as allogrooming and inter-male mounting, was drastically reduced. These findings suggest that the social buffering effect is impaired as nursery-reared monkeys had experienced less social contact in a novel environment. Thus, impairment of mother-infant bonding strongly influences offspring sociality in human and non-human primates (Agid et al., 1999; Heim and Nemeroff, 2001), although details of the underlying mechanisms are not yet fully understood. Additionally, because the bonding formation is established during the process of social communication between mother and infants, social cognition has a pivotal influence on the bonding process (Ross and Young, 2009). However, little information has been obtained regarding the role of each social cue in the formation of bonds.

In the present review, we describe the manner in which mutual communication between mother and infant leads to mother-infant bonding in rodents. We emphasize the significance of the conserved oxytocin neural system in mother-infant bond information, with several studies having shown that oxytocin plays a fundamental role in establishing this bond (Kendrick, 2000; Young et al., 2001; Wang and Aragona, 2004; Young and Wang, 2004). Other neurotransmitters that regulated social bonding, such as opioids and dopamine are also important, however, we would concede these issues in other articles. We also review the effects of deprivation of mother-infant bonding, by studying the consequences of early weaning on neurobehavioral development in rodent offspring. Intensive maternal care has evolved and has been preserved, uniquely in mammals, and it is highly probable that mother-infant bonding is universal to all mammalian species. These comparative points of view provide insights into the biological significance of mother-infant bonding in mammals; a comparative understanding of the developmental consequences of this bonding and its underlying mechanisms, even in rodents, may help in our treatment or prevention of disorders associated with child abuse or childhood neglect (Agid et al., 1999; Heim and Nemeroff, 2001).

Suter Science Seminar (2010) - Caring: How We Become Attached

This is an older but fascinating seminar lecture (yes, I am a geek, and I rejoice in my geekiness) on creating healthy (secure) attachments through Care Theory. Dr. Nel Noddings is Lee L. Jacks Professor of Education, Emerita, at Stanford University and a past president of the National Academy of Education, the Philosophy of Education Society, and the John Dewey Society.

Her many books include Caring: A Feminine Approach to Ethics and Moral Education (2003), The Challenge to Care in Schools (2005), and Philosophy of Education (2011).




Suter Science Seminar (2010) - Caring: How We Become Attached
Many educators today express interest in attachment theory. Children who have not formed secure attachments to their early caregivers often experience social problems in school and neighborhood activities. Care theory is useful in explaining how secure attachments are formed. Caring relations are important at every stage of life, and caring teachers can be instrumental in enriching the lives of their students, often well into adolescence. Care theory also offers a powerful approach to moral education.

The Great Attachment Debate - How important is early experience?

http://www.simplypsychology.org/harlow-monkey.jpg

The March/April issue of Psychotherapy Networker offered a series of articles on The Great Attachment Debate: How important is early experience? It looks as though the articles are freely available online, so I'm going to give a taste of each one - you can read the ones that interest you.

The image above is from one of the pioneering studies that led to attachment theory - Harry Harlow and Zimmerman (1959) found that infant rhesus monkeys raised in isolation would either die or exhibit severe mental illness. When raised with a choice between two surrogates, a cloth covered monkey shape or a wire monkey with a source of food, the infants would cling to the cloth mother, aside from brief trips to the wire mother for food. Some would not leave the cloth mother and starved to death.

Interestingly, these studies were inspired by work done by John Bowlby (Maternal Care and Mental Health published in 1951) that looked at maternal deprivation. This work was inspired by the Freudian Rene Spitz, who had observed infants in foundling homes at the end of WWII:
In 1945 he did research on hospitalism in children in a foundling home. He found that the developmental imbalance caused by the unfavourable environmental conditions during the children's first year produces a psychosomatic damage that cannot be repaired by normal measures.
Essentially, the neglect these children suffered in being left alone all day with only brief feedings prevented them from attaching to another human being (it doesn't have to be the mother) and the ones who did not die suffered severe psychopathology.

Harlow's experiments are now seen as cruel and unnecessary, but they influenced John Bowlby to further the line of inquiry, which led (with the profound assistance of Mary Ainsworth) to our modern attachment theory.

Among the authors in this collection of essays are Dan Siegel, Jerome Kagan, and Mary Sykes Wylie, all well know psychologists and authors. The final piece is actually a short story by Bruce Jay Friedman that I quite liked and certainly is relevant to the discussion represented in these articles.

The Verdict Is In

The case for attachment theory

By Alan Sroufe and Daniel Siegel

While many schools of psychotherapy have held that our early experiences with our caretakers have a powerful impact on our adult functioning, there have been plenty of hard-nosed academics and researchers who've remained unconvinced. Back in 1968, psychologist Walter Mischel created quite a stir when he challenged the concept that we even have a core personality that organizes our behavior, contending instead that situational factors are much better predictors of what we think and do. Some developmental psychologists, like Judith Rich Harris, author of The Nurture Assumption, have gone so far as to argue that the only important thing parents give their children is their genes, not their care. Others, like Jerome Kagan, have emphasized the ongoing influence of inborn temperament in shaping human experience, asserting that the effect of early experience, if any, is far more fleeting than is commonly assumed. In one memorable metaphor, Kagan likened the unfolding of life to a tape recorder with the record button always turned on and new experiences overwriting and erasing previous experiences. n At the same time, the last 50 years have seen the accumulation of studies supporting an alternative view: the idea that the emotional quality of our earliest attachment experience is perhaps the single most important influence on human development. The central figure in the birth of this school of research has been British psychiatrist and psychoanalyst John Bowlby, who challenged the Freudian view of development, claiming that it had focused too narrowly on the inner world of the child without taking into account the actual relational environment that shapes the earliest stages of human consciousness.

Bowlby's thinking was influenced by his study of how other mammals rear their young, and the distinctive core of his contribution to developmental psychology may be traced to a very simple observation: whereas young ground-dwelling animals run to a place of protection when frightened, primates like chimpanzees and gorillas run to a protective adult, who then carries them to safety. As he focused on the developmental significance of this survival pattern, Bowlby concluded that humans—the most dependent of mammal infants—are wired like their primate cousins to form attachments, because they couldn't survive without them.

But Bowlby went further. While agreeing with his psychoanalytic colleagues that early experiences with our caretakers are crucial to the people we become, he made an important distinction. Infants are attached to their caregivers not because caregivers feed them, but because caregivers trigger the unfolding of infants' inborn disposition to seek closeness with a protective other. By divorcing human attachment from the drive-reduction notions of Freudian theory, Bowlby laid the foundation for a shift from seeing people as individuals somehow standing apart from their social environment to a more fine-tuned grasp of just how deeply relational human nature is.

Bringing Up Baby

Are we too attached?

By Jerome Kagan

One of the strongest articles of faith among psychotherapists is the intuitively attractive proposition that the security of early attachments to parents has a profound influence on adult mental health. Thousands of articles, books, and conferences have probed this topic, and many therapists have made attachment theory a cornerstone of their clinical approach. Even clinicians who aren't particularly loyal to attachment theory accept the general proposition that the quality of infants' emotional experiences with their caretakers affects their vulnerability to psychological disorders as adults. However, when I examine the evidence for this belief as a research psychologist, rather than as a clinical practitioner, a different, less clear-cut picture emerges. Three major assumptions underlie attachment theory. First, variation in the caretaker's interactions with the infant creates variation in the infant's emotional bond to that person. This bond is called an attachment. Most psychologists, including this writer, regard this assumption as true and proven by evidence. Second, the consequences of the quality of the early attachment are preserved for many years and influence the older child and adult's personality and vulnerability to pathology. This assumption, as we shall see, is far from proven. The final premise involves the measurement of the infant's quality of attachment. As we shall see, many psychologists believe that an experimental procedure called the Strange Situation is a sensitive measure of the different types of infant attachments. This assumption, too, is a hypothesis still awaiting confirmation. A theory that rests on three assumptions, only one of which has consensual validity, should require closer examination before being embraced as indisputably true. But many clinicians believe that all three assumptions of attachment theory have been proven to be correct.

Attachment Theory in Perspective

Some influential ideas in the social sciences have their roots in the life experiences of the creator and his or her culture. This appears to be true of attachment theory. Let us consider the life experiences of the British psychiatrist John Bowlby, the father of attachment theory. As the fourth of six children growing up in an upper-middle-class London family, Bowlby, born in 1907, and his siblings were cared for by nurses on the top floor of the family's spacious home. He recalled seeing his mother for perhaps an hour each day after teatime, and his father, a prominent surgeon, once a week. His favorite nanny, with whom he had a close relationship, left the household when he was 4. By 7, he'd been sent to a boarding school. He later said of that experience, "I wouldn't send a dog away to boarding school at age 7."

Of course, we can't know whether the frequent separations from parents and the loss of the nanny contributed to Bowlby's strong ideas about attachment. We do know, however, that from the beginning of his career, he was unusually sensitive to the importance of a child's experience of parental love. He'd been trained in psychoanalytic theory and had a personal analyst. At age 21, he worked for a short time at a progressive school for emotionally disturbed children. Some of these children had experienced early separation from their parents or obvious neglect, and Bowlby interpreted their disturbed behavior patterns as support for his belief that a mother's love for a child was vital for healthy psychological development—as vital as good nutrition is for physical growth.

The Attuned Therapist

Does attachment theory really matter?

by Mary Sykes Wylie and Lynn Turner

Five hundred people sat in a packed workshop at the Networker Symposium last March, listening to eminent developmental psychologist and researcher Jerome Kagan draw on more than four decades of research he's conducted as he discussed the clinical relevance of inborn temperament. Midway through the session, responding to a question from the audience, he tried to clarify an earlier, seemingly disparaging, comment he'd made about attachment theory. But he soon removed any possible doubt about where he stood. "I'm glad that attachment theory is dead," he said. "I never thought it would go anywhere."

There was a moment of stunned silence, followed by a low hum as people shifted in their seats and murmured to each other. Whatever their imperfect understanding of the voluminous research literature of attachment theory, for most therapists in the room, the idea that the early emotional attunement of a mother/caregiver (or lack of it) profoundly affects the child's psychological development was as self-evident as the worthiness of therapy itself. Indeed, during the last 15 to 20 years, attachment theory has exerted more influence in the field of psychotherapy than just about any other model, approach, or movement. Though not a clinical methodology, it has justified a whole range of therapeutic perspectives and practices. Among them are a particular sensitivity to the role of traumatic or neglectful ties with early caregivers; the fundamental importance of affect regulation to successful therapy; the importance of establishing relationships with clients characterized by close, intense, emotional, and physical attunement; and the ultimate goal of recreating in therapy an attachment experience that makes up, at least to some degree, for what the client missed the first time around. That attachment theory itself has amassed a vast body of empirical evidence (see p.34) is often taken, by extension, to cast a glow of scientific credibility on attachment-based therapy. So when Kagan delivered his offhand rebuke, he was raising fundamental questions about the evidence supporting findings that most therapists there considered not just theory, but well-established fact.

Suddenly, in the wordless void that followed Kagan's bombshell, psychiatrist, brain researcher, and staunch attachment theory proponent Daniel Siegel popped out of his seat, looked for a floor microphone to respond, and, finding none, strode up the center aisle and bounded onto the stage. As a startled Kagan looked on and the entire ballroom audience sat dumbfounded, Siegel, the conference keynote speaker from that morning, asked for a microphone and announced: "I can't let this audience listen to your argument without hearing the other side. Have you actually read the attachment research?" he demanded of his colleague.

There followed a heated, impromptu debate between the two men that later became the talk of the conference. Part of the buzz was because it was a disagreement between two stars—Jerome Kagan, arguably the most revered developmental psychologist in the world, and Daniel Siegel, one of the most influential thinkers and teachers in the field of psychotherapy today. Each brought to bear both an impressive resume and passionately held convictions on the age-old question about human development: which counts more—nature or nurture? Beyond its sheer drama, two things stood out about this spontaneous encounter—the surprise that a discussion of research findings could generate such intellectual fervor at a psychotherapy conference and, for the majority of the audience, the shock that there was any debate at all about the role of early experience in human development. It was as if a leading biologist had gotten up at a professional conference to denounce germ theory.

In the world of psychotherapy, few models of human development have attracted more acceptance and respect in recent years than the centrality of early bonding experiences to adult psychological well-being. Nevertheless, the Kagan–Siegel encounter brought to the surface a barely visible fault line between true believers in attachment and its doubters, who not only question the idea that the quality of the mother-child attachment always and permanently affects a child's psychological development, but whether attachment theory itself has had a positive or negative influence on the practice of psychotherapy. It raised the question of whether the growing centrality of attachment theory has begun to blind the field to other vital influences on a person's development—inborn temperament, individuation needs, family dynamics, even class and culture—which all lie outside the mother–child dyad.

But what on earth could ever be wrong with emphasizing early bonding, connection, and relationship as the foundation of all good therapy? Are there ever times when too much "attunement" and "empathy" can constrict a therapist's clinical repertoire and obfuscate the issues with which clients should deal? For those for whom this debate focuses on a theory that wasn't even on their grad-school curriculum, what's all the fuss about, and what exactly does attachment theory tell us that we haven't known since the days of Freudian analysis?

The Nightgown

In search of the answerman

By Bruce Jay Friedman

Stranded in Manhattan on a holiday weekend, Nat Solomon, a visiting academic from Detroit, decided to treat himself to an off-Broadway play. The production had received tepid reviews, but he was intrigued by the theme: a Catholic priest had begun to doubt his faith. Rather than speak to his bishop—he'd been there before—the priest decided to reach beyond the church and consult a psychiatrist.

Solomon had lost three of them; that is to say, a trio of psychiatrists had died on him. They were old men; he'd sought them out for their wisdom. It had never occurred to him that, one by one, they'd expire, which they did just as he was getting somewhere. Undeterred, he tried again—this time a Jungian. She was clearly a compassionate woman. Still, when she learned of the three dead shrinks, she turned color and refused to take him on as a patient.

At the moment, Solomon had no one. When it came to his mental health, he was flying solo, barely holding his life together—a distant wife, a rudderless daughter, shrinking income, and crumbling knees. It was quite a package.

He lucked out and got an aisle seat in the tiny theater—the better to stretch out his left knee, the one that gave him the most trouble. Both performers in the two-character play were accomplished, but Solomon couldn't take his eyes off the actor who played the psychiatrist. Never before had he seen such compassion in a therapist's face. Each time the priest cried out in anguish, the therapist cried out with him, though silently (if such a thing was possible). The few times the therapist spoke, his words trembled with humility and quiet strength—a difficult combination to pull off. Solomon waited for him to stroke his chin, an unbearable cliche. Stroke it he did, although the stroke was closer to the ear than the chin, which made a world of difference. When the therapist drummed his fingers on his desk, Solomon did some drumming of his own—on the armrest. The priest had been waffling. The drumming was a gentle nudge: get to the heart of what's eating you.

There was a slight trace of cockney in the psychiatrist's voice, which was appealing. There was a puckish grin in the mix. All of it was irresistible.
