What is Attachment Theory? Bowlby’s 4 Stages Explained

Attachment Theory in Children and Adults: Bowlby & Ainsworth's 4 TypesIs it all your mother’s fault?

No matter what the “it” refers to, Sigmund Freud would have probably said yes to that question.

However, we now know a lot more about psychology, parenting, and human relationships than Freud did.

It’s clear now that not every issue can be traced back to one’s mother. After all, there is another person involved in the raising (or at least the creation) of a child.

In addition, there are many other important people in a child’s life who influence him or her. There are siblings, grandparents, aunts and uncles, godparents, close family friends, nannies, daycare workers, teachers, peers, and others who interact with a child on a regular basis.

The question posed above is tongue-in-cheek, but it touches upon an important discussion in psychology—what influences children to turn out the way they do? What affects their ability to form meaningful, satisfying relationships with those around them?

What factors contribute to their experiences of anxiety, avoidance, and fulfillment when it comes to relationships?

Although psychologists can pretty conclusively say that it’s not entirely the mother’s fault or even the fault of both parents, we know that a child’s early experiences with their parents have a profound impact on their relationship skills as adults.

Much of the knowledge we have on this subject today comes from a concept developed in the 1950s called attachment theory. This theory will be the focus of this article: We’ll explore what it is, how it describes and explains behavior, and what its applications are in the real world.

What is Attachment Theory? A Definition

The psychological theory of attachment was first described by John Bowlby, a psychoanalyst who researched the effects of separation between infants and their parents (Fraley, 2010).

Bowlby hypothesized that the extreme behaviors infants engage in to avoid separation from a parent or when reconnecting with a physically separated parent—like crying, screaming, and clinging—were evolutionary mechanisms. Bowlby thought these behaviors had possibly been reinforced through natural selection and enhanced the child’s chances of survival.

These attachment behaviors are instinctive responses to the perceived threat of losing the survival advantages that accompany being cared for and attended to by the primary caregiver(s). Since the infants who engaged in these behaviors were more likely to survive, the instincts were naturally selected and reinforced over generations.

These behaviors make up what Bowlby termed an “attachment behavioral system,” the system that guides us in our patterns and habits of forming and maintaining relationships (Fraley, 2010).

Research on Bowlby’s theory of attachment showed that infants placed in an unfamiliar situation and separated from their parents will generally react in one of these ways upon reunion with the parents:

  1. Secure attachment: These infants showed distress upon separation but sought comfort and were easily comforted when the parents returned;
  2. Anxious-resistant attachment: A smaller portion of infants experienced greater levels of distress and, upon reuniting with the parents, seemed both to seek comfort and to attempt to “punish” the parents for leaving.
  3. Avoidant attachment: Infants in the third category showed no stress or minimal stress upon separation from the parents and either ignored the parents upon reuniting or actively avoided the parents (Fraley, 2010).
  4. In later years, researchers added a fourth attachment style to this list: the disorganized-disoriented attachment style, which refers to children who have no predictable pattern of attachment behaviors (Kennedy & Kennedy, 2004).

It makes intuitive sense that a child’s attachment style is largely a function of the caregiving the child receives in his or her early years. Those who received support and love from their caregivers are likely to be secure, while those who experienced inconsistency or negligence from their caregivers are likely to feel more anxiety surrounding their relationship with their parents.

However, attachment theory takes it one step further, applying what we know about attachment in children to relationships we engage in as adults. These relationships (particularly intimate and/or romantic relationships) are also directly related to our attachment styles as children and the care we received from our primary caregivers (Firestone, 2013).

The development of this theory gives us an interesting look into the study of child development.

Bowlby and Ainsworth: The History and Psychology of Attachment Theory

John Bowlby attachment theory

Bowlby’s interest in child development traces back to his first experiences out of college, in which he volunteered at a school for maladjusted children. According to Bowlby, two children sparked his curiosity and drive that laid the foundations of attachment theory.

There was an isolated and distant teenager who had no stable mother figure in his life and had recently been expelled from his school for stealing, and an anxious 7- or 8-year-old boy who followed Bowlby wherever he went, earning himself a reputation as Bowlby’s “shadow” (Bretherton, 1992).

Through his work with children, Bowlby developed a strong belief in the impact of family experiences on children’s emotional and behavioral wellbeing.

Early on in his career, Bowlby proposed that psychoanalysts working with children should take a holistic perspective, considering children’s living environments, families, and other experiences in addition to any behaviors exhibited by the children themselves.

This idea grew into a strategy of helping children by helping their parents, a generally effective strategy given the importance of the child’s relationships with their parents (or other caregivers).

Mary Ainsworth attachment theory

At roughly the same time Bowlby was creating the foundations for his theory on attachment, Mary Ainsworth was finishing her graduate degree and studying security theory, which proposed that children need to develop a secure dependence on their parents before venturing out into unfamiliar situations.

In 1950, the two crossed paths when Ainsworth took a position in Bowlby’s research unit at the Tavistock Clinic in London. Her initial responsibilities included analyzing records of children’s behavior, which inspired her to conduct her own studies on children in their natural settings.

Through several papers, numerous research studies, and theories that were discarded, altered, or combined, Bowlby and Ainsworth developed and provided evidence for attachment theory.

Theirs was a more rigorous explanation and description of attachment behavior than any others on the topic at the time, including those that had grown out of Freud’s work and those that were developed in direct opposition to Freud’s ideas (Bretherton, 1992).

Research and Studies

There were several groundbreaking studies that contributed to the development of attachment theory or provided evidence for its validity, including the study described earlier in which infants were separated from their primary caregivers and their behavior was observed to fall into a “style” of attachment.

Further findings on emotional attachment came from a surprising place: rhesus monkeys.

The Harlow Experiments

attachment theory Harlow experimentsIn the 1950s, Harry Harlow was conducting experiments on love and relationships between parents and children, specifically monkey parents and children.

His work showed that motherly love was emotional rather than physiological, that the capacity for attachment is heavily dependent upon experiences in early childhood, and that this capacity was unlikely to change much after it was “set” (Herman, 2012).

Harlow discovered these interesting findings by conducting two groundbreaking experiments.

In the first experiment, Harlow separated infant monkeys from their mothers a few hours after birth. Each monkey was instead raised by two inanimate surrogate “mothers.” Both provided the infant monkeys with the milk they needed to survive, but one was made out of wire mesh while the other was wire mesh covered with soft terry cloth.

The monkeys who were given the freedom to choose which mother to associate with almost always chose to take milk from the terry cloth “mother.” This finding showed that infant attachment is not simply a matter of where they get their milk—other factors are at play.

For his second experiment, Harlow modified his original setup. The monkeys were given either the bare wire mesh surrogate mother or the terry cloth mother, both of which provided the milk the monkeys needed to grow.

Both groups of monkeys survived and thrived physically, but they displayed extremely different behavioral tendencies. Those with a terry cloth mother returned to the surrogate when presented with strange, loud objects, while those with a wire mesh mother would throw themselves to the floor, clutch themselves, rock back and forth, or even “scream in terror.”

This provided a clear indication that emotional attachment in infancy, gained through cuddling, affected the monkey’s later responses to stress and emotion regulation (Herman, 2012).

These two experiments laid the foundations for further work on attachment in children and the impacts of attachment experiences in later life.

Erik Erikson

Erik Erikson attachment theory Erik Erikson’s research trajectory was parallel to Bowlby and Ainsworth’s but came from a different perspective.

Erikson’s work was based on Freud’s original personality theories and drew from his idea of the ego. However, Erikson placed more importance on context from culture and society than on Freud’s focus on the conflict between the id and the superego.

In addition, his stages of development are based on how children socialize and how it affects their sense of self rather than on sexual development.

The eight stages of psychosocial development according to Erikson are:

  1. Infancy—Trust vs. Mistrust: In this stage, infants require a great deal of attention and comfort from their parents, leading them to develop their first sense of trust (or, in some cases, mistrust);
  2. Early Childhood—Autonomy vs. Shame and Doubt: Toddlers and very young children are beginning to assert their independence and develop their unique personality, making tantrums and defiance common;
  3. Preschool Years—Initiative vs. Guilt: Children at this stage begin learning about social roles and norms. Their imagination will take off at this point, and the defiance and tantrums of the previous stage will likely continue. The way trusted adults interact with the child will encourage him or her to act independently or to develop a sense of guilt about any inappropriate actions;
  4. School Age—Industry (Competence) vs. Inferiority: At this stage, the child is building important relationships with peers and is likely beginning to feel the pressure of academic performance. Mental health issues may begin at this stage, including depression, anxiety, ADHD, and other problems.
  5. Adolescence—Identity vs. Role Confusion: The adolescent is reaching new heights of independence and is beginning to experiment and put together his or her identity. Problems with communication and sudden emotional and physical changes are common at this stage (Wells, Sueskind, & Alcamo, 2017).
  6. Young Adulthood—Intimacy vs. Isolation: At this stage (ages 18-40, approximately), the individual will begin sharing with others more, including people outside o the family. If the individual is successful in this stage of development, he or she will build satisfying relationships that have a sense of commitment, safety, and care; if not, they may fear commitment and experience isolation, loneliness, and depression (McLeod, 2017).
  7. Middle Adulthood—Generativity vs. Stagnation: In the penultimate stage (ages 40-65, approximately), the individual is likely established in his or her career, relationship, and family. If the individual is not established and contributing to society, he or she may feel stagnant and unproductive.
  8. Late Adulthood—Ego Integrity vs. Despair: Finally, late adulthood (ages 65 and above) usually brings reduced productivity, which can either be embraced as a reward for one’s contributions or be met with guilt or dissatisfaction. Successfully navigating this stage will protect the individual from feeling depressed or hopeless, and help the individual cultivate wisdom (McLeod, 2017).

Although it does not map completely onto attachment theory, Erikson’s findings are clearly related to the attachment styles and behaviors Bowlby, Ainsworth, and Harlow identified.


John Bowlby – Attachment Theory – Diana Simon Psihoterapeut

Attachment Theory in Babies, Infants, and Early Childhood Development

According to Bowlby and Ainsworth, attachments with the primary caregiver develop during the first 18 months or so of the child’s life, starting with instinctual behaviors like crying and clinging (Kennedy & Kennedy, 2004). These behaviors are quickly directed at one or a few caregivers in particular, and by 7 or 8 months old, children usually start protesting against the caregiver(s) leaving and grieve for their absence.

Once children reach the toddler stage, they begin forming an internal working model of their attachment relationships. This internal working model provides the framework for the child’s beliefs about their own self-worth and how much they can depend on others to meet their needs.

In Bowlby and Ainsworth’s view, the attachment styles that children form based on their early interactions with caregivers form a continuum of emotion regulation, with anxious-avoidant attachment at one end and anxious-resistant at the other.

Secure attachment falls at the midpoint of this spectrum, between overly organized strategies for controlling and minimizing emotions and the uncontrolled, disorganized, and ineffectively managed emotions.

The most recently added classification, disorganized-disoriented, may display strategies and behaviors from all across the spectrum, but generally, they are not effective in controlling their emotions and may have outbursts of anger or aggression (Kennedy & Kennedy, 2004).

Research has shown that there are many behaviors in addition to emotion regulation that relates to a child’s attachment style. Among other findings, there is evidence of the following connections:

  • Secure Attachment: These children are generally more likely to see others as supportive and helpful and themselves as competent and worthy of respect. They relate positively to others and display resilience, engage in complex play and are more successful in the classroom and in interactions with other children. They are better at taking the perspectives of others and have more trust in others;
  • Anxious-Avoidant Attachment: Children with an anxious-avoidant attachment style are generally less effective in managing stressful situations. They are likely to withdraw and resist seeking help, which inhibits them from forming satisfying relationships with others. They show more aggression and antisocial behavior, like lying and bullying, and they tend to distance themselves from others to reduce emotional stress;
  • Anxious-Resistant Attachment: These children are on the opposite end of the spectrum from anxious-avoidant children. They likely lack self-confidence and stick close to their primary caregivers. They may display exaggerated emotional reactions and keep their distance from their peers, leading to social isolation.
  • Disorganized Attachment: Children with a disorganized attachment style usually fail to develop an organized strategy for coping with separation distress, and tend to display aggression, disruptive behaviors, and social isolation. They are more likely to see others as threats than sources of support, and thus may switch between social withdrawal and defensively aggressive behavior (Kennedy & Kennedy, 2004).

It is easy to see from these descriptions of behaviors and emotion regulation how attachment style in childhood can lead to relationship problems in adulthood.

Attachment Theory in Adults: Close Relationships, Parenting, Love, and Divorce

Indeed, it is clear how these attachment styles in childhood lead to attachment types in adulthood. Below is an explanation of the four attachment types in adult relationships.

Examples: The Types, Styles, and Stages (Secure, Avoidant, Ambivalent, and Disorganized)

The adult attachment styles follow the same general pattern described above (Firestone, 2013):

Secure Attachment

These adults are more likely to be satisfied with their relationships, feeling secure and connected to their partners without feeling the need to be together all the time. Their relationships are likely to feature honesty, support, independence, and deep emotional connections.

Dismissive-Avoidant (or Anxious-Avoidant) Attachment

One of the two types of adult avoidant attachments, people with this attachment style generally keep their distance from others. They may feel that they don’t need human connection to survive or thrive, and insist on maintaining their independence and isolation from others.

These individuals are often able to “shut down” emotionally when a potentially hurtful scenario arises, such as a serious argument with their partner or a threat to the continuance of their relationship.

Anxious-Preoccupied (or Anxious-Resistant) Attachment

Those who form less secure bonds with their partners may feel desperate for love or affection and feel that their partner must “complete” them or fix their problems.

While they long for safety and security in their romantic relationships, they may also be acting in ways that push their partner away rather than invite them in. The behavioral manifestations of their fears can include being clingy, demanding, jealous, or easily upset by small issues.

Fearful-Avoidant (or Disorganized) Attachment:

The second type of adult avoidant attachment manifests as ambivalence rather than isolation. People with this attachment style generally try to avoid their feelings because it is easy to get overwhelmed by them. They may suffer from unpredictable or abrupt mood swings and fear getting hurt by a romantic partner.

These individuals are simultaneously drawn to a partner or potential partner and fearful of getting to close. Unsurprisingly, this style makes it difficult to form and maintain meaningful, healthy relationships with others.

Each of these styles should be thought of as a continuum of attachment behaviors, rather than a specific “type” of person. Someone with a generally secure attachment style may on occasion display behaviors more suited to the other types, or someone with a dismissive-avoidant style may form a secure bond with a particular person.

Therefore, these “types” should be considered a way to describe and understand an individual’s behavior rather than an exact description of someone’s personality.

Based on a person’s attachment style, the way he or she approaches intimate relationships, marriage, and parenting can vary widely.

The number of ways in which this theory can be applied or used to explain behavior is compounded and expanded by the fact that relationships require two (or more) people; any attachment behaviors that an individual displays will impact and be influenced by the attachment behaviors of other people.

Given the huge variety of individuals, behaviors, and relationships, it is not surprising that there is so much conflict and confusion.

It is also not surprising, although no less unfortunate, that many relationships end up in divorce or dissolution, an event that may continue an unhealthy cycle of attachment in the children of these unions.

Attachment Theory in Grief and Trauma

Speaking of unfortunate situations, attachment theory also has applications in the understanding of the grief and trauma associated with loss.

Although you may be most familiar with Kübler-Ross’s Five Stages of Grief, they were preceded by Bowlby’s Four Stages. During Bowlby’s work on attachment, he and his colleague Colin Murray Parkes noticed four stages of grief:

  1. Shock and Numbness: In this initial phase, the bereaved may feel that the loss is not real, or that it is simply impossible to accept. He or she may experience physical distress and will be unable to understand and communicate his or her emotions.
  2. Yearning and Searching: In this phase, the bereaved is very aware of the void in his or her life and may try to fill that void with something or someone else. He or she still identifies strongly and may be preoccupied with the deceased.
  3. Despair and Disorganization: The bereaved now accepts that things have changed and cannot go back to the way they were before. He or she may also experience despair, hopelessness, and anger, as well as questioning and an intense focus on making sense of the situation. He or she might withdraw from others in this phase.
  4. Reorganization and Recovery: In the final phase, the bereaved person’s faith in life may start to come back. He or she will start to rebuild and establish new goals, new patterns, and new habits in life. The bereaved will begin to trust again, and grief will recede to the back of his or her mind instead of staying front and center (Williams & Haley, 2017).

Of course, one’s attachment style will influence how grief is experienced as well. For example, someone who is secure may move through the stages fairly quickly or skip some altogether, while someone who is anxious or avoidant may get stuck on one of the stages.

We all experience grief differently, but viewing these experiences through the lens of attachment theory can bring new perspective and insight into our unique grieving processes and why some of us get “stuck” after a loss.

The Attachment Theory Test

attachment theory attachment style

If you’re interested in learning about your attachment style, there are many tests, scales, and questionnaires out available for you to take.

Feeny, Noller, and Hanrahan developed the Original Attachment Three-Category Measure in 1987 to test respondents’ adult attachment style. It contains only three items and is very simple, but it can still give you a good idea of which category you fall into: avoidant, anxious/ambivalent, or secure. You can complete the measure yourself or read more about it on page 3 of this PDF.

Bartholomew and Horowitz’s Relationships Questionnaire added to The Three-Category Measure by expanding it to include the dismissive-avoidant category. You can find it on the same PDF as the Three-Category Measure, starting on page 3.

Fraley, Waller, and Brennan’s Experiences in Close Relationships Questionnaire-Revised (ECR-R) is a 32-item questionnaire that gives results measured by two subscales related to attachment: avoidance and anxiety (Fraley, Waller, & Brennan, 2000). Items are rated on a scale from 1 (strongly disagree) to 7 (strongly agree). You can find this questionnaire on the final three pages of the PDF mentioned above.

In addition to these scales, there are several less rigorous attachment style tests that can help you learn about your own style of connecting with others. These aren’t instruments often used in empirical research, but they can be helpful tools for learning more about yourself and your attachment style.

Diane Poole Heller developed an Attachment Styles Test, which contains 45 items rated on a three-point scale from “Rarely/Never” to “Usually/Often.” You can find it here, although after completing it you must enter an email to receive your results.

The Relationship Attachment Style Test is a 50-item test hosted on Psychology Today’s website. It covers the four attachment types noted earlier (Secure, Anxious-Ambivalent, Dismissive-Avoidant, Fearful-Avoidant) as well as Dependent and Codependent attachment styles.

If you are interested in taking this test, you can find it at this link. However, be aware that while you receive a free “snapshot report” at the end, you will need to pay to see your full results.

Using Attachment Theory in the Classroom (Worksheet and PDF)

Using Attachment Theory in the Classroom (Worksheet + PDF)Because of its importance to child development, attachment theory has major implications for the classroom.

One of the ways in which the principles and concepts of attachment theory have been effectively applied to teaching is the practice of emotion coaching.

Emotion coaching is about helping children to become aware of their emotions and to manage their own feelings particularly during instances of ‘misbehavior.’ It enables practitioners to create an ethos of positive learning behavior and to have the confidence to de-escalate situations when behavior is challenging” (National College for Teaching and Leadership, 2014).

Emotion coaching is more about supporting children in learning about and regulating their own emotions and behavior than it is about “coaching” in the traditional sense. In emotion coaching, teachers are not required—or even encouraged—to promote proper behavior through rewards or punishments.

Instead, emotion coaching involves:

  • Teaching students about the world of “in the moment” emotion;
  • Showing students strategies for dealing with emotional ups and downs;
  • Empathizing with and accepting negative or unpleasant emotions as normal, but not accepting negative behavior;
  • Using moments of challenging behavior as opportunities for teaching;
  • Building trusting and respectful relationships with the students (National College for Teaching and Leadership, 2014).

According to attachment theory expert Dr. John Gottman, there are five steps to emotion coaching, and they can be practiced by parents, teachers, or any significant adult in a child’s life:

  1. Tune in: Notice or become aware of your own and the child’s emotions. Make sure you are calm enough to practice emotion coaching, otherwise, you might want to give both of you a quick breather;
  2. Connect: Use this situation as an opportunity for you to practice and for the child to learn. State objectively (This is important!) what emotions you think the child is experiencing to help them connect their emotions to their behavior;
  3. Accept and Listen: Practice empathy. Put yourself in the child’s shoes, think about a situation when you felt a similar emotion, and try to remember what it felt like;
  4. Reflect: Once everyone is calm, go back over what the child said or did, mentioning only what you saw, heard, or understand of the situation. Reflect on what happened and why it happened;
  5. End with Problem Solving/Choices/Setting Limits: Whenever possible, try to end the situation by guiding or involving the child in problem-solving (Somerset Children & Young People, n.d.).

To learn more about emotion coaching and improve your skills as a parent or teacher, try the following activity.

What Would an Emotion Coach Do?

This short, two-page activity from the Somerset Emotion Coaching Project can help you enhance your understanding of what emotion coaching is—and what it is not.

There are five scenarios presented along with six potential responses. Your task is to read the scenario and decide which response(s) is/are the appropriate emotion coaching response(s).

The first scenario is: “Angry pupil over not wanting to attend a compulsory revision session.”

Your options include:

  • Get cross with the pupil for the bad behavior;
  • Tell the pupil they will have to complete an extra session due to the bad behavior;
  • Help the pupil to think about what they can do about the problem;
  • Tell the pupil not to make a big deal about staying after school;
  • Validate the pupil’s expression of anger and frustration;
  • Soothe the pupil.

This is an excellent activity to do in groups, as you can discuss each option with others and hear different perspectives from your own. In addition to identifying the emotion coaching response(s), you can also discuss which options are dismissive, avoidant, etc.

You can see the rest of the scenarios and try your hand at this activity by clicking here (an automatic download will start when you click on the link).

Emotion Coaching Scripts

Another great resource from the Somerset Emotion Coaching Project, this activity gives you a chance to practice brainstorming emotion coaching-appropriate responses.

As an added bonus, you can use the scripts you develop to guide you the next time you encounter a situation like those described.

There are six scenarios which you are instructed to create a script for:

  1. A pupil arrives late to class. She refuses to communicate with you and says “Don’t even start, just leave me alone”;
  2. A young person refuses to sit by her usual friends at a youth center and says that they have been saying unkind comments about her size;
  3. A boy regularly fails to complete work independently and will often sit passively and contribute little. He rarely presents with disruptive behavior but simply completes very little work. He appears isolated from his peers;
  4. A nursery child is crying at drop-off time and is clinging to her parent who has to go to work;
  5. An aggressive, confrontational parent is annoyed because she’s been asked to come in and talk about her son’s behavior. She approaches you and starts the conversation by saying, “You’re always having a go at us”;
  6. During recess, a group of young boys was fighting and one of them was hurt (not seriously). You approach them and they all look at you with worried expressions.

For each scenario, the instructions encourage you to:

  1. Recognize the emotion the child is displaying;
  2. Validate that emotion;
  3. Label the emotion the child is feeling;
  4. Empathize with the child;
  5. Set limits, if appropriate, and problem-solve.

Completing this worksheet provides you with an excellent opportunity to think, plan, and prepare for effective emotion coaching. You can download this activity for your own use here (an automatic download will start when you click on the link).

If you’re interested in learning more about applying attachment theory to teaching, check out Louis Cozolino’s book Attachment-Based Teaching: Creating a Tribal Classroom. He puts forth a simple but potentially game-changing idea: Relationships are the key to better performance rather than rigidly structured curricula.

In addition, our article Attachment Styles in Therapy: Worksheets & Handouts provides useful worksheets pertaining attachment styles.

Attachment Theory in Social Work

Emotion coaching can also be used by social workers, to some extent. However, the application of attachment theory to social work is more significant in the three key messages that it espouses:

  1. It is vital for social workers to offer children and families a safe haven and secure base. This does not mean families should be forever comfortable and come to depend on the social worker, but families should know a social worker can provide a safe place when they are struggling as well as support for moving forward and outward;
  2. Social workers must be aware of children’s (and their families’) inner experiences and practice mentalization, or “bringing the inside out.” One of the most important factors in finding healing and improving family relations is to ensure that parents have an idea of what is going on in their children’s heads, including how they feel and think about their parents;
  3. Among the most effective tools in a social worker’s toolbox is the practice of recording parents as they interact with their child and using the videos to coach the parent. Valuable insights can be found in watching oneself parenting, and the social worker can provide in the moment coaching, offering praise for the parents’ strengths alongside suggestions for improvement (Shemmings, 2015).

Of course, there are many ways to apply attachment theory to working with children, especially those who are in the midst of family crises. However, if these three points are attended to, you’ll have the most important bases covered.

For social workers who work with adults, there are some different strategies and key points to keep in mind, specifically:

  • Remember that attachment theory applies throughout the entire range of life, and many behaviors and processes are shaped by early attachment, including staying safe, seeking comfort, regulating proximity to the attachment figure, and seeking predictability;
  • Keep in mind that attachment patterns are not based on a few key moments, but on thousands of moments throughout early life, and how an attachment figure responds (or does not respond) sets a template for the child’s attachment style in the future. This template affects how the child recognizes and responds to their own emotions and how they interact with attachment figures;
  • This early template becomes deeply embedded in the brain and therefore has a significant impact on our ability to regulate our emotions and connect and relate to others in adulthood. This can lead an adult who was abused in childhood to fail to recognize that they are being abused in their intimate relationship, or even cause them to find comfort and stability in the predictability of their situation;
  • Remember that attachment behaviors are adaptive to the context in which they were formed. Habits and behaviors that are adaptive in childhood, in an evolutionary sense at least, may become maladaptive and harmful in adulthood;
  • Finally, social workers should never think that they are “treating” a set of behaviors and must recognize that the individual’s strategies were formed for a reason and likely helped him or her survive a difficult situation in childhood. The role of a social worker is to help clients avoid overapplying those strategies and to guide them in adding effective, new strategies to their toolboxes (Hardy, 2016).

Criticisms of Attachment Theory

As with any popular theory in psychology, there are several criticisms that have been raised against it.

Chief among them are the following criticisms:

  • Overemphasis on Nurture: This criticism stems from psychologist J. R. Harris, who believes that parents do not have as much of an influence over their child’s personality or character as most people believe. She notes that much of one’s personality is determined by genetics rather than environment (Harris, 1998; Lee, 2003).
  • Limitations of the Model:
    • The stressful situation criticism of attachment theory’s limitations notes that the model was based on a child’s reactions in momentary, stressful situations (being separated from one’s parent), and does not provide any insight into how children and parents interact in non-stressful situations;
    • Further, the early model did not take into consideration the fact that children can have different kinds of attachments to different people; the attachment with the mother may not represent the attachments formed with others;
    • Finally, the mother was viewed as the automatic primary attachment figure in the early model, when the father, stepparent, sibling, grandparent, aunt, or uncle may be the person that the child connects most strongly with (Field, 1996; Lee, 2003).

Although some of these criticisms have faded over time as the theory is injected with new evidence and updated concepts, it is useful to look at any theory with a critical eye.

A Take-Home Message

This piece tackled attachment theory, a theory developed by John Bowlby in the 1950s and expanded upon by Mary Ainsworth and countless other researchers in later years. The theory helps explain how our childhood relationships with our caregivers can have a profound impact on our relationships with others as adults.

Although attachment theory may not be able to explain every peculiarity of personality, it lays the foundations for a solid understanding of yourself and those around you when it comes to connecting and interacting with others.

What do you think about attachment theory? Do you think there are attachment styles not covered by the four categories? Are there any other criticisms of attachment theory you think are valid and worthy of discussion? We’d love to hear your thoughts in the comment section.

    muchas gracias por la información

    The linked surveys are problematic, when they refer to intimate or close relationships, particularly for persons who’ve only had one close adult relationship. Or none.

  3. Matt Bennett

    Article is defective (‘to’ instead of ‘too’ aside). Cannot – for the life of me – find the four stages of attachment declared at the outset; only four styles. For what’s it’s worth I experienced paternal absence and maternal rejection – prostitute mother and pimp father – which is to say, no parenting or attachment at all – leading to a hotch-potch of all three non-secure ‘styles’.

  4. Rhema Tembo

    how does attachment influences personality development in adulthood.

    • Nicole Celestine, Ph.D.

      Hi Rhema,

      Good question! We answer this question by linking the different attachment styles to adult behaviors traits in this article: https://positivepsychology.com/attachment-style-worksheets/ (see the subsection ‘Attachment Theory in Psychology: 4 Types & Characteristics’)

    How do I reference this article

    • Nicole Celestine, Ph.D.

      Hi Aine,

      You can reference this article in APA 7th as follows: Ackerman, C. A. (2018, April 27). What is Attachment Theory? Bowlby’s 4 stages explained. PositivePsychology.com. https://positivepsychology.com/attachment-theory/

      Hope this helps!

    I think that a big limitation when discussing Attachment Theory, that I haven’t seen addressed, is the effect of trauma on a older child past the early defining stage, or an adult. Bullying, accidents and injury, severe illness, family upheaval, or other significant life events can significantly affect a person’s psychological state, and thus alter a Securely Attached style to one of the other types.

    Thank you for an informative article! Do you happen to know of any non-profit organizations that focus on stopping the cycle of maladaptive attachment in families? I’m a student with some ideas for a program that I’d like to pitch to some organizations that serve at risk individuals.

    • Nicole Celestine

      Hi AH,

      Glad you found the article helpful — that sounds like an interesting idea! Your question’s a little tricky. It’s hard to know how explicitly existing services draw on Bowlby’s principles. However, I suspect that the messages of the framework are likely embedded in various parent support groups and educational opportunities. If you’re interested in the U.S. specifically, maybe check out some of the services listed here and inquire about any curriculums.

      Hope this helps!
