Attachment Theory: What Does It Say? Why Is It Crucial?

Last updated by Lauren Hart

“What was your childhood like?” When we consult a psychologist, we always get asked this question during the first session. It’s logical because a lot of trauma occurs during this pivotal period. Obviously, it’s also a way of finding out whether the attachment to an adult took place properly. This is a crucial concept in psychology, theorized by the psychiatrist John Bowlby. What is the theory of attachment? Why is it crucial? Here’s what you need to know about attachment.

Attachment Theory: What Does It Say? Why Is It Crucial?

The origins of the theory

At Wengood, we’ve already talked to you about John Bowlby, particularly through romantic attachment. However, we haven’t gone back over the origins of attachment theory and its importance 🧐. In 1951, the psychiatrist published a report entitled “Maternal Care and Mental Health” for the World Health Organization (WHO) on conditions in nurseries. From then on, he set out to understand the effects of prolonged separation on young children.

At the time, too little attention was paid to the relationship between children and their environment. With Freud, the focus was more on drives. Nevertheless, Bowlby refuted Freud and began to talk about “attachment” in his writings. He went on to demonstrate that babies are predisposed to attachment and that the attachment bond is crucial in meeting the child’s primary needs.

How does attachment develop according to the theory?

Additional studies have reinforced Bowlby’s work in 1978, in particular, that of Ainsworth, Blehar, Waters, and Wall on the stages of attachment 🍼:

  • From 0 to 3 months, pre-attachment phase: the baby will activate attachment behaviors through crying, but there’s no main figure yet.
  • From 3 to 6 months, emergence phase: behaviors will diversify, and the baby will have a particular person as a figure.
  • From 6 months to 2 years: the child has a reference figure and needs one whenever they’re feeling unwell.
  • From the age of 2: multiple attachments are established because the child’s security needs have been met by the main figure.

To find out how a child forms an attachment, we can identify two types of behavior. The child will seek out their main figure (the “caregiver”) in order to feel secure and will protest if they’re separated. Attachment generally takes the form of crying, clinging on, screaming, smiling, etc. In short, any signal they can give to show that they need their attachment figure to regulate their needs and emotions.

🤔 Is it always the mother who’s the main attachment figure?

According to the theory, there’s only one main attachment figure. It’s usually the mother because women have the mental load of the child in our society. But that doesn’t mean there can’t be other strong, subsidiary attachment figures.

Why do we need attachment?

With these studies complementing the theory, it’s clear that we need at least one reference figure during childhood. According to Bowlby, this is crucial if we are to develop in a balanced way. Indeed, children are incapable of managing their emotions on their own or surviving if they don’t have someone to look after them. They also need a warm, consistent and predictable relationship in order to thrive.

Above all, having an attachment figure prevents us from developing fears. Yes, if there was the slightest imbalance during early childhood, we can develop a fear of abandonment, for example 🤕.

📌 My testimonial

I’ve always been afraid of being abandoned for as long as I can remember. This has inevitably had an impact on my relationships with friends and lovers. I’ve had an insecure attachment for a long time, and it was through therapy that I identified one of the reasons for this behavior.

My parents were away for several months when I was a baby, and I was about 1 when they went on a humanitarian trip. My grandparents looked after me at that time and even though I was safe, not seeing my parents during that stage of my development had a strong impact on my personality.

I wouldn’t call it a trauma now, but it’s undeniable that it was one of the reasons for my fear of abandonment, my lack of confidence and my self-sabotage in love. Of course, it’s not the only avenue I’ve explored through therapy, but it’s one of them.

Is the theory always proven?

This theory put forward by the psychiatrist remains fairly central to therapies today. It’s a dominant approach to the creation of emotional bonds in children and has been the basis of a lot more research on the subject. Nonetheless, there have been subsequent criticisms, particularly that it doesn’t cover all aspects of social relationships. Indeed, social relationships are complex, and attachment theory has its limits and can’t explain all our adult social behaviors 🤔. Going back to my example, even though I’ve dug deeper into this aspect with my psychological care, I know that it’s not the only reason I’m the way I am. There are so many things to take into account that it’s difficult to say it’s the only cause in my case.

We therefore need to take a step back and look at all the possibilities. Attachment theory is an important concept to consider, especially when you’re a parent, but it’s not the only determining factor. If you have fears or a lack of confidence and need to understand where they come from, don’t hesitate to seek help.

Editor’s note: An interesting approach

Attachment theory is an interesting one and allows you to reflect on your childhood and your experiences. If you feel that something isn’t right or that there’s something to explore in this area, don’t hesitate to contact a psychologist so that together you can take stock and put in place new habits and ways of thinking to help you be happier.

🤗 Understanding yourself, accepting yourself, being happy... It’s here and now!

8 Reasons Why Malignant Narcissists Are So Dangerous

If the title of this article hasn’t totally scared you away, then you are no doubt wondering what this beast of a person is really like. Well, a malignant narcissist is a step up from a typical narcissist and adds an antisocial personality disorder to the already intimidating mixture.

What Are The Weaknesses Of A Narcissist?

Each one of us has our own weaknesses that hold us back in life; be it at work or in relationships. However, on a more positive note, most of us have the will to work on them and transform them. That being said, once narcissists are brought into the picture, the idea that they want to work on their weaknesses doesn’t exactly seem feasible.

I Never Thought I’d Say This, But I Hate Working From Home…

Work has always been a synonym of repression for me because it takes up so much of our precious time. Let’s be honest, a 9-5 job with a horrendous daily commute often means that work is sadly our sole occupation. So, when the Covid-19 pandemic struck over a year ago, and we were all ordered to stay home, I found it hard to hide my joy in front of my distraught coworkers; although thankfully my acting talents saved me. You can probably already tell, but going into the office every day was nothing less than torture for me. Yet, all these months later, I’ve realized that I despise working from home and would do anything to sit in my uncomfortable office chair once again!

Do We Always Need To Have The Last Word?

Today, I’m focussing on a habit that drives me crazy: wanting to have the last word.

But why do they always want to have the last word? What’s behind it?

I Still Suck My Thumb As An Adult

In general, thumb sucking ends around the age of 6. I say “in general” and not “normally”, because as an adult I don’t feel weird or particularly bothered by it. When I get stressed, I allow myself to let go and return to my childhood self by sucking my thumb. Those who know about it or catch me by surprise make me realize I should be ashamed… But is this habit a big deal? What if it makes me feel better? It’s certainly no worse than lighting up a cigarette or biting your nails…

Why Do Hugs And Physical Contact Make Me Feel Uncomfortable?

There are people who don’t like to be touched at all, and who are almost disgusted by physical contact. There are people who like to caress and be caressed for anything and everything, and there are people like me who always recoil when someone tries to touch them. Why do I shy away from physical contact? What if it’s all linked to the past?
