Attachment, Neurodivergence and Trust: A Critical Analysis of Bowlby, Ainsworth and the Commercial Relevance of the AmbiSense® Model
Written and researched by Naomi Withers

Introduction
Attachment theory offers one of the most influential explanations for how early relationships shape later emotional, social and relational development. Originally developed by John Bowlby and expanded through Mary Ainsworth’s observational research, attachment theory proposes that children form emotional bonds with caregivers as a means of protection, regulation and survival (Bowlby, 1969/1982; Ainsworth et al., 1978). These early relationships do not simply provide care in the moment; they also help shape a child’s expectations of self, others and the wider world.
A central claim of attachment theory is that repeated caregiving experiences create what Bowlby called internal working models: mental and emotional templates that influence how individuals expect relationships to work (Bowlby, 1969/1982). These templates may affect whether a person expects others to be safe, available, consistent, rejecting, intrusive or unreliable. For this reason, attachment theory is especially useful when considering trust issues later in life. Trust can be understood not merely as a conscious decision, but as a learned prediction about whether closeness, need, vulnerability and dependence are safe.
However, attachment theory must be used critically. It can explain important links between early relational experience and later trust, but it should not be treated as a deterministic or single-cause theory. Trust difficulties may also be shaped by trauma, neurodivergence, sensory experience, cultural context, discrimination, family systems, school experiences, workplace harm and later relationships. This is particularly important when considering neurodivergent children and adults. Neurodivergent people can and do form secure attachments, but their route to felt safety may require more individualised, sensory-aware and communication-aware environments.
This review critically analyses Bowlby and Ainsworth’s contribution to attachment theory, explores how attachment affects trust issues later in life, considers the relationship between attachment and neurodivergence, and evaluates how the AmbiSense® model can translate this theory into a commercially useful framework for families, schools and workplaces.
Bowlby: Attachment as a Survival System
Bowlby’s theory was grounded in the idea that attachment is an evolved behavioural system. From this perspective, the infant’s need for closeness is not simply emotional dependence; it is a survival strategy. When a child experiences threat, distress, separation or uncertainty, the attachment system is activated and the child seeks proximity to a caregiver who can provide protection and regulation (Bowlby, 1969/1982).
This is where Bowlby’s concepts of the secure base and safe haven are significant. A caregiver acts as a secure base when the child can explore the world knowing that support is available if needed. The caregiver acts as a safe haven when the child can return for comfort, protection and co-regulation during distress (Bowlby, 1988). In this sense, attachment is not simply about affection; it is about whether the child’s body and mind learn that help is available when stress becomes too much.
Bowlby also introduced the concept of internal working models. These are experience-based models of the self and others. A child who repeatedly receives sensitive, predictable and comforting responses may develop a working model such as: “I am worthy of care, and others can be trusted to help me.” In contrast, a child who repeatedly experiences rejection, inconsistency, frightening caregiving or emotional absence may develop a working model such as: “My needs are unsafe,” “people leave,” “I must manage alone,” or “closeness comes with danger.”
A major review of attachment research explains that Bowlby saw the attachment behavioural system as organised by internal working models of the self and environment, especially the caregiving environment (Cassidy et al., 2013). The same review describes secure-base scripts as key building blocks of these models. For example, a secure-base script might involve the expectation that when a person is hurt or distressed, they can seek comfort from another person and receive help (Cassidy et al., 2013).
This is directly relevant to trust later in life. If trust is partly built through repeated evidence that others are available, safe and repair-capable, then repeated experiences of inconsistency, fear, rejection or misattunement may create later difficulties with trust. These difficulties should not be understood simply as irrational or resistant. They may be protective adaptations based on what the person’s relational history has taught them to expect.
Ainsworth: The Strange Situation and Attachment Patterns
Mary Ainsworth expanded Bowlby’s theory by developing observational methods for studying attachment behaviour. Her most influential contribution was the Strange Situation Procedure, which observed infants’ responses to separation and reunion with a caregiver (Ainsworth et al., 1978). The child’s behaviour during reunion was especially important because it revealed whether the caregiver functioned as a source of comfort and regulation.
Ainsworth and colleagues identified three main attachment classifications: secure, insecure-avoidant and insecure-ambivalent/resistant (Ainsworth et al., 1978). Securely attached children may show distress when separated from the caregiver but are generally comforted on reunion and able to return to exploration. Avoidantly attached children may appear outwardly independent and avoid or ignore the caregiver on reunion. Ambivalent or resistant children may show high distress and seek contact while also resisting comfort.
A fourth category, disorganised attachment, was later identified by Main and Solomon (1990). Disorganised attachment describes contradictory, confused, frozen or fearful behaviours, often understood as arising when the caregiver is simultaneously needed and feared. This category is particularly relevant in the context of trauma, frightening caregiving, unresolved parental trauma, or environments where the child cannot develop a coherent strategy for achieving safety.
Ainsworth’s work was significant because it gave attachment theory an observable research base. Her Strange Situation Procedure became a “gold standard” for identifying infant attachment security and insecurity, influencing decades of later research (Cassidy et al., 2013). However, it also requires critical analysis. The Strange Situation is a brief laboratory-based procedure, and attachment behaviour may be influenced by temperament, culture, disability, neurodivergence, prior separation experience and wider family context. It is therefore useful, but not sufficient, as a full explanation of a child’s relational world.
Trust Later in Life: Internal Working Models and Adult Relationships
Attachment theory has been extended beyond infancy into adult relationships. Bowlby argued that attachment applies “from the cradle to the grave”, and later researchers explored how attachment patterns may shape romantic relationships, friendships and adult support-seeking (Fraley, n.d.; Hazan and Shaver, 1987). Adult attachment research suggests that the same motivational system involved in infant-caregiver bonds may influence adult emotional bonds, particularly in relationships involving closeness, dependence, separation and distress.
Fraley (n.d.) explains that adult attachment research is based on three key assumptions. First, adult romantic relationships may involve attachment dynamics similar to infant-caregiver relationships. Second, secure and insecure patterns may appear in adult relationships, affecting support-seeking, intimacy and conflict. Third, adult attachment security may partly reflect earlier caregiving experiences, because internal working models influence how people perceive and behave in relationships.
Secure adults are more likely to expect that others will be available when needed. They may be more comfortable with intimacy, dependence, mutual support and repair. Fraley (n.d.) notes that secure adults tend to report greater relationship satisfaction, trust, commitment, longevity and interdependence. They are also more likely to seek support when distressed and provide support to partners.
Insecure attachment may affect trust in different ways. Anxious attachment can involve heightened fear of abandonment, sensitivity to distance, reassurance seeking and difficulty believing that care will remain. This can be understood as a hyperactivated attachment strategy: when closeness feels uncertain, the individual increases proximity-seeking or monitoring in an attempt to preserve connection.
Avoidant attachment can involve discomfort with closeness, reluctance to depend on others, emotional distancing and a strong emphasis on self-reliance. This can be understood as a deactivated attachment strategy: if depending on others has historically led to rejection, disappointment or intrusion, the individual may reduce visible need in order to maintain safety.
Disorganised attachment may produce more conflicted trust patterns. A person may want closeness but fear it, seek connection but expect harm, or move between pursuit, withdrawal, shutdown and defensive anger. In this case, trust is complicated because the attachment figure may have historically been both a source of comfort and a source of threat.
A contemporary study of adult attachment and psychological wellbeing found that secure attachment dimensions were positively associated with wellbeing, while anxious and avoidant attachment dimensions were negatively associated with wellbeing (Marrero-Quevedo et al., 2023). The study also describes secure attachment as involving confidence in oneself and others, ease of trusting others and comfort with mutual dependence (Marrero-Quevedo et al., 2023). This supports the argument that attachment is closely linked to trust, self-concept and relational functioning.
A Critical Interpretation of Trust Issues
Through an attachment lens, trust issues should not be reduced to unwillingness, weakness or emotional immaturity. A more accurate interpretation is that trust issues are often learned safety predictions. They represent what a person has come to expect from closeness, need and vulnerability.
If someone has repeatedly experienced emotional absence, rejection, inconsistency, shame, intrusion, frightening caregiving or unresolved conflict, their nervous system may learn that trust is risky. Later in life, this can show up as hypervigilance, reassurance seeking, withdrawal, difficulty asking for help, fear of abandonment, discomfort with intimacy or strong reactions to perceived rejection.
This is where attachment theory is especially useful. It shifts the question from:
“Why can’t this person just trust?”
to:
“What has this person learned to expect when they need someone?”
This is a more compassionate and analytically useful question. It makes space for the idea that mistrust may have been adaptive in earlier contexts, even if it later becomes limiting.
However, attachment should not be used as a fixed label. A person is not simply “an avoidant” or “an anxious attachment style”. Attachment patterns are relational, contextual and changeable. A person may feel safe in one relationship and unsafe in another. They may trust friends but not authority, partners but not workplaces, or colleagues but not family. Later safe relationships, therapy, mentoring, community, repair and repeated experiences of consistency can all update internal working models.
Attachment and Neurodivergence
The relationship between attachment and neurodivergence requires careful analysis. Neurodivergence includes natural variations in brain development and functioning, including autism, ADHD, dyslexia, dyspraxia and sensory processing differences. Attachment theory can help explain how trust develops, but it must not be used to pathologise neurodivergent communication, sensory needs or behaviour.
A critical mistake would be to assume that neurodivergent relational differences automatically indicate attachment difficulty. For example, an autistic child avoiding eye contact, needing space, struggling with transitions, using direct communication, shutting down under overload or resisting demands may be misread as avoidant, oppositional or relationally insecure. In reality, these behaviours may reflect sensory overload, communication difference, executive-function stress, masking fatigue or the need for predictability.
Research on attachment in autistic children supports this caution. A 2025 systematic review and meta-analysis found that autistic children assessed using the Strange Situation Procedure showed attachment classifications that were statistically similar to general-population proportions: 45.6% secure, 18.7% avoidant, 8.5% resistant and 27.2% disorganised (Aubé et al., 2025). This is important because it challenges the assumption that autism prevents secure attachment. Autistic children can form secure attachments, but their attachment behaviours may look different and require careful interpretation.
A neuro-affirming attachment lens therefore asks:
What helps this person experience safety?
How does this person communicate distress?
What sensory conditions affect their regulation?
How have adults interpreted their behaviour?
Have their needs been understood or repeatedly misread?
What does repair look like for this person?
Are we seeing attachment insecurity, neurodivergent difference, trauma, environmental mismatch, or a combination?
Neurodivergent people may develop trust issues not because neurodivergence causes insecure attachment, but because the world repeatedly misunderstands or misattunes to them. A child whose sensory distress is treated as bad behaviour may learn that adults are unsafe during overwhelm. An ADHD child repeatedly labelled lazy or careless may learn that others will eventually be disappointed in them. A dyslexic child repeatedly exposed through public reading or writing tasks may learn that formal systems are unsafe. An autistic adult required to mask in order to be accepted may learn that acceptance is conditional.
In this sense, internal working models are not shaped only by the family. They are also shaped by schools, workplaces, peer groups, medical systems and social expectations. For neurodivergent people, trust may be relational, sensory, environmental and institutional.
Critical Strengths of Attachment Theory
Attachment theory has several strengths. First, it explains trust as relational learning rather than moral weakness. This is valuable because it helps practitioners, educators, parents and leaders move away from blame. If trust develops through repeated evidence of safety, then mistrust may reflect repeated evidence of unsafety.
Second, attachment theory links emotional regulation with relationships. It shows that people do not learn regulation in isolation. They learn through co-regulation, repair, predictable care and the repeated experience of being helped through distress.
Third, attachment theory offers practical intervention points. If internal working models can be shaped by repeated experiences, then new patterns of safety and repair can help rebuild trust. This supports approaches based on consistency, attunement, predictable routines, clear boundaries and relational repair.
Fourth, attachment theory has a large research base. Bowlby’s theoretical work, Ainsworth’s observational methods and later adult attachment research have generated extensive evidence across developmental psychology, clinical practice and relationship science (Cassidy et al., 2013; Fraley, n.d.; Marrero-Quevedo et al., 2023).
Critical Limitations of Attachment Theory
Despite its strengths, attachment theory has limitations. One risk is determinism. If attachment is presented too rigidly, it can imply that early childhood fixes later relational outcomes. This is inaccurate and potentially harmful. Attachment patterns may show continuity, but they are not destiny. Later relationships and environments can challenge and update earlier internal working models.
A second limitation is the risk of caregiver blame, particularly mother-blame. Attachment theory has historically focused heavily on the mother-child relationship. This can obscure the role of fathers, wider family, poverty, parental mental health, disability, domestic abuse, social support, school systems and structural pressures. A more ethical approach must recognise that caregivers operate within wider systems.
A third limitation is cultural bias. The Strange Situation was developed in particular cultural contexts. Behaviours such as independence, proximity-seeking, emotional expression or distress during separation may carry different meanings across cultures. What looks avoidant in one context may be shaped by cultural norms around independence or emotional restraint.
A fourth limitation concerns neurodivergence. Attachment theory can be misapplied when neurodivergent behaviour is interpreted through a neurotypical lens. Social communication differences, sensory needs, shutdown, demand avoidance, direct communication or masking fatigue should not automatically be interpreted as attachment insecurity. Attachment-informed work with neurodivergent people must also be neuro-affirming, sensory-informed and context-aware.
AmbiSense®: Translating Theory into Commercial Support
The AmbiSense® model can be positioned as a practical bridge between attachment theory, neurodivergence and real-world systems. Attachment theory explains how trust and safety are built through repeated relational experience. Neurodivergence explains why felt safety must be personalised according to sensory, cognitive, communication and regulatory needs. AmbiSense® can translate these insights into practical emotional infrastructure for families, schools and workplaces.
The commercial value of AmbiSense® is that it does not sell abstract theory. It turns complex psychological insight into a repeatable method for identifying where trust, safety and functioning repeatedly break down. In AmbiSense® language, these are repeated pressure points or hot windows. The model then supports the creation of Calm Bridges™: practical scripts, routines, ownership routes and repair steps that help reduce escalation and rebuild predictability.
This is commercially significant because buyers are usually not looking for attachment theory itself. Schools, parents and workplaces are looking for help with visible problems:
attendance issues
emotionally based school avoidance
SEND conflict
behaviour escalation
parent-school mistrust
staff overwhelm
workplace conflict
burnout
psychological safety
neurodivergent inclusion
repeated breakdowns in communication
inclusion that exists on paper but not in practice
AmbiSense® can reframe these issues as repeated moments where the person, relationship and system are not fitting well enough. This creates a practical route from theory to intervention.
For example, in a school context, a pupil’s repeated distress during morning arrival might be understood through attachment theory as a separation or safety issue, through a neurodivergent lens as a transition, sensory or predictability issue, and through AmbiSense® as a hot window requiring a Calm Bridge™. The intervention might include a predictable arrival routine, a known adult, reduced sensory load, a visual transition map, and a repair script if the morning becomes difficult.
In a workplace, a neurodivergent employee’s withdrawal after feedback might be misunderstood as defensiveness. Through an attachment-informed and neuro-affirming lens, it may reflect shame, rejection sensitivity, previous experiences of criticism, unclear expectations or sensory overload. AmbiSense® could help the organisation build a feedback bridge: clearer preparation, private delivery, written follow-up, emotional pacing, agreed next steps and a repair route.
This is where the commercial positioning becomes clear:
AmbiSense® turns attachment-informed and neuro-affirming theory into practical emotional infrastructure. It helps schools, families and workplaces move from repeated escalation to repeated evidence of safety, trust and repair.
The model supports commercial viability because it connects psychological theory to measurable operational outcomes. It can help schools evidence inclusion, reduce escalation, improve parent trust, support staff consistency and create better conditions for neurodivergent pupils. It can help workplaces move beyond generic wellbeing and towards practical systems that reduce conflict, support psychological safety and retain neurodivergent talent. It can help parents understand repeated family pressure points without blame, shame or overcomplicated theory.
Conclusion
Bowlby and Ainsworth’s attachment theory provides a powerful framework for understanding how early relationships influence later trust. Bowlby’s concept of internal working models explains how children develop expectations about whether others are safe, available and reliable. Ainsworth’s Strange Situation research gave attachment theory an observational base by identifying secure and insecure patterns of attachment behaviour. Later adult attachment research shows that these patterns may influence trust, support-seeking, conflict, intimacy and psychological wellbeing.
However, attachment theory must be applied critically. It should not be used deterministically, reductively or in ways that blame caregivers without considering wider systems. It must also be used carefully in relation to neurodivergence. Neurodivergent people can form secure attachments, but their attachment behaviours and safety needs may look different. Trust difficulties may arise not from neurodivergence itself, but from repeated misattunement, sensory overload, masking demands, misunderstanding and environmental mismatch.
The strongest conclusion is that attachment affects trust through learned predictions of safety. These predictions may begin early, but they can change through later repeated experiences of consistency, attunement and repair. This is where AmbiSense® has commercial strength. It translates attachment-informed and neuro-affirming understanding into practical emotional infrastructure. By identifying repeated pressure points, mapping hot windows, installing Calm Bridges™ and tracking pattern change, AmbiSense® gives families, schools and workplaces a clear method for rebuilding trust and improving functioning.
In simple terms:
Attachment theory explains how trust is built. Neurodivergence shows why safety must be personalised. AmbiSense® shows how to build the practical bridges that make trust possible.
