Science Bulletins: Attachment Theory—Understanding the Essential Bond
Summary
TLDRThe video discusses John Bowlby's research on child-mother separation during WWII, highlighting the importance of attachment behavior. Bowlby observed that children and primates seek proximity to their caregivers for emotional security, not just nutrition. Modern programs based on his theories help parents form secure attachments with their children, especially those with difficult childhoods. Secure attachment correlates with better mental and physical health, impacting cortisol levels and reducing inflammation-related diseases. The video emphasizes the lifelong importance of early attachment and the biological consequences of early life adversity.

Q & A
Who was John Bowlby and what was he known for?
-John Bowlby was a British psychologist known for his work on child-mother separation during the bombing of London and his development of attachment theory.
What did Bowlby observe about the children sent to the countryside during the bombing of London?
-Bowlby observed that, despite being well-cared for and safe, the children had a very negative response to being separated from their mothers.
What biological observations did Bowlby make from primatology that influenced his theories?
-Bowlby observed that monkey infants, even after being weaned, sought proximity and contact with their mothers, suggesting a lifelong desire for attachment and contact.
What did Bowlby and others identify as cornerstones of attachment behavior?
-Bowlby and others identified proximity-seeking and contact-seeking as cornerstones of attachment behavior.
How did Bowlby’s views differ from those of behaviorists and psychoanalysts in the early 20th century?
-Behaviorists and psychoanalysts believed that babies loved their parents primarily because they provided food. Bowlby argued that children also need to be held and cared for by understanding, sensitive, and responsive adults.
What is the primary goal of the program at the Center for Babies, Toddlers, and Families?
-The primary goal is to help parents and children form a secure attachment, particularly focusing on parents who had difficult childhoods themselves.
What challenges did Pearl Castillo face in parenting, and how did the intervention help her?
-Pearl Castillo struggled with patience and handling her child's crying due to her own neglected childhood. The intervention helped her learn to focus on her child and better tolerate and respond to the crying.
How do researchers at the Center for Attachment Research measure attachment relationships?
-They use a laboratory scenario that takes 20 minutes, including a critical point where the mother leaves the room and researchers observe the child's response.
What are the characteristics of a securely attached child according to the observations made in the lab scenario?
-A securely attached child often notices when the caregiver leaves, cries, and then is comforted easily upon the caregiver's return, achieving a state of homeostasis.
What long-term consequences of early life adversity are highlighted by Bruce McEwen?
-Bruce McEwen highlights both psychological effects, such as substance abuse and depression, and biological consequences, including increased incidence of cardiovascular disease and diabetes, often linked to chronic inflammation.
What role does cortisol play in the body's response to early life adversity and chronic inflammation?
-Cortisol is important for turning down inflammation after an infection is contained. However, in cases of traumatic experiences, the cortisol response may not function properly, leading to elevated levels of inflammation and associated health issues.
How is cortisol measured in the studies conducted by the Center for Babies, Toddlers, and Families?
-Cortisol is measured through saliva samples taken upon arrival at the lab and at the end of the lab visit.
What changes have been observed in families who participated in the intervention for six months or more?
-Families who participated for six months or more showed attachment security levels at 70%, comparable to global averages, and researchers hope to see corresponding improvements in cortisol responses.
What overall message does Bruce McEwen convey about early life adversity and attachment?
-Bruce McEwen emphasizes the importance of taking early life adversity seriously, highlighting that early attachment is crucial to mental and physical health and is a fundamental part of human development.

👶 The Origins of Attachment Theory
James J. Warfield explains John Bowlby’s interest in child-mother separation, inspired by the London bombings. Despite being cared for in the countryside, children exhibited strong negative reactions to separation from their mothers. Bowlby observed similar behaviors in primates, noting the critical role of proximity-seeking and contact in attachment behavior. Howard Steele highlights Bowlby’s insight that children need more than nourishment—they need emotional warmth and responsive care for optimal mental health, a concept supported by decades of evidence.
👨👩👧👦 The Impact of Early Life on Parenting
Anne Murphy discusses how their program at the Center for Babies, Toddlers, and Families is based on Bowlby’s theories, aiming to help parents and children establish secure attachments. Pearl Castillo shares her struggles with parenting due to her own neglectful childhood, often reacting with impatience and anger to her baby's cries. Anne explains how neglected parents may relive their childhood traumas, making it difficult to meet their child’s needs.
🧪 Measuring Attachment and Cortisol Levels
Miriam Steele describes their partnership with the Center for Attachment Research at The New School to develop attachment measures. They use a 20-minute laboratory scenario to observe the mother-child attachment, noting differences in children's reactions to their caregiver's departure and return. Securely attached children seek comfort and return to homeostasis, while others remain physiologically aroused. This response is crucial for mental health, as Bruce McEwen points out the long-term effects of early life adversity on both psychological and physical health.
🌡️ Inflammation and Cardiovascular Risks
Bruce McEwen explains how chronic inflammation, linked to early life trauma, can lead to cardiovascular disease. Inflammation is a natural immune response, but when cortisol regulation fails, inflammation persists, increasing disease risk. Anne Murphy mentions measuring cortisol through saliva samples to track changes over time, aiming to improve cortisol patterns through their intervention. Howard Steele notes initial low attachment security in families, but after six months, 70% achieved normal attachment security, correlating with healthier cortisol responses.
❤️ Improving Parental Focus and Emotional Regulation
Pearl Castillo shares her transformation through the intervention, now able to handle her child's crying better and manage her depression. Bruce McEwen summarizes the key lesson from studies on early life adversity: it is a significant biological issue, with early attachment being crucial to lifelong well-being. Secure attachment forms the foundation for all future development and mental health.

Transcripts
JAMES J. WARFIELD: John Bowby was a British psychologist.
And he became extremely interested
in child-mother separation during the bombing of London.
The bombing of London, a lot of parents
sent their kids to the safety of the countryside.
And the kids were with safe people.
They were well cared for.
They were well-fed.
But they still had a very negative response
to the separation from their mothers.
At that point, he looked at the biology that
was emerging in primatology.
A monkey infant gets almost all its nutrition the first two
or three months of life from its mother from lactation.
But the infant who is weaned still seeks proximity.
You'll see the infant reach out and touch the mom's tail
or touch its coat.
There is a continuing lifelong desire
for proximity and contact.
And Bowlby and others have seen that proximity-seeking
and that contact-seeking as being cornerstones of what
they call attachment behavior.
HOWARD STEELE: In the first part of the 20th century,
behaviorists and psychoanalysts claimed
that babies love their parents because you don't want to bite
the hand that feeds you.
The innovation of Bowlby was to observe
that that can't be all, that what the child needs
is not only to be fed, but also to be held
by an understanding, sensitive, and responsive adult.
And that optimal social and mental health outcomes will
follow from that.
And 60 or more years on now, we have a half century
of evidence showing that he was more or less right.
ANNE MURPHY: Our program at the Center for Babies, Toddlers,
and Families is really based on the theories
of John Bowlby with the idea that we really
need to help parents and children form
a secure attachment.
So oftentimes, families are referred to us
when the parents have had very difficult childhoods themselves
and are really struggling in this role of being a parent.
PEARL CASTILLO: And like I said, I never had a mommy.
I was never taught how to take care of anybody or myself.
So it was like very hard, like I wouldn't have patience,
like the crying.
I would scream at her and stuff like that.
ANNE MURPHY: For many parents who really were neglected
as children, hearing a baby cry triggers in them
their own feelings of that unrelenting
crying that they did.
So for Pearl, it was very, very difficult
for her to be able to meet her child's needs.
PEARL CASTILLO: Push it.
Push this button.
Yeah, hard.
Push it.
ANNE MURPHY: We've partnered with the Center for Attachment
Research at The New School for a series of attachment measures
to test that our intervention is effective.
MIRIAM STEELE: So come on in, Pearl.
That's going to be your chair.
So just put her down, and let her have a go at whatever she
wants to do here.
We measure the attachment relationship
with a laboratory scenario that takes 20 minutes.
The critical point is where the mother
gets a cue to leave the room.
PEARL CASTILLO: Bye, baby girl.
See you later.
MIRIAM STEELE: Some children look on the outside
like they're very independent and seem not to notice
but physiologically are very aroused
and stay aroused even in the presence
of when that caregiver returns.
By contrast, the securely attached child
often notices, cries when the caregiver leaves,
and when the caregiver comes back,
easily turns to the caregiver, and looks to the caregiver
to be comforted.
And then they can get back to some kind of homeostasis.
PEARL CASTILLO: OK, you play with them.
MIRIAM STEELE: We think this response
is one of the hallmarks of mental health.
BRUCE MCEWEN: What is so interesting
about childhood development is that we
know a lot about the long-term, lifelong consequences
of early life adversity, ranging from psychological effects,
like substance abuse and depression, but also
biological consequences, like increased incidence
of cardiovascular disease, diabetes, and a whole host
of other physical ailments.
One of the things we know that can lead down
the path towards cardiovascular disease
is chronic inflammation.
Inflammation is a biological response
that helps the body counteract an infection.
The body produces chemicals, which
activate the immune system and allow it to get rid
of the infective agent.
When the infection is contained, the body
calls forth cortisol to try to turn down the inflammation.
Now this is all good.
But there are situations, especially connected
with traumatic experiences, in which that cortisol response
doesn't happen.
So these people who had these adverse early life experiences
had elevated levels of inflammation,
which is at the heart of cardiovascular disease.
So cortisol is very important.
ANNE MURPHY: Yum, yum, yum.
Almost done.
Good work.
That's my boy.
The way that we measure cortisol is through a saliva sample
obtained upon arrival at the lab and at the end of the lab
visit.
And our goal is to, over time, impact patterns of cortisol.
PEARL CASTILLO: Is that OK?
HOWARD STEELE: Our initial measurements
of these families when they were beginning the intervention,
we see very low levels of attachment security
as measured by their behavior.
But when we look at families who have participated
for six months or more, we see attachment security
at 70%, the same level seen worldwide.
Because higher levels of attachment security correlate
with more normal cortisol responses,
we're hoping to see their cortisol levels
change as a result of the intervention.
PEARL CASTILLO: The main thing was it helped me
a lot to focus on my child.
Before I could tolerate the crying.
It would make me crazy, and I used to be depressed.
But now, I mean, sometimes I can't take it.
But I know better now.
BRUCE MCEWEN: What have we learned from the studies
of early life adversity?
What we've learned is to take it seriously,
that these are real biological issues.
That early attachment is vital to everything else that
happens, something that is an inevitable part of who
we are as human beings.
