Chapter 15: Attachment Theory II: Development and Function

A foundational pillar of the theory is the belief that childhood interactions, particularly with parents, establish working models of self and others that serve as a skeleton for adult personality. Critically, unlike classic psychoanalysis, attachment theory posits that these mental representations are not exclusively based on early experiences but are environmentally labile and can be updated throughout life by contemporary relationships and situational contexts. This developmental flexibility is constrained by two opposing forces: homeothetic forces promoting stability and buffering against deviation from early prototypes, and destabilizing forces encouraging revision due to powerful, attachment-relevant experiences, such as stressful life events or abuse,. Research confirms that continuity of attachment is a dynamic process where early security influences later socio-emotional functioning across the lifespan, fitting the prototype model better than continuous change,. The psychodynamic module details the fears and defenses arising from attachment insecurity. Avoidant deactivation is a defense strategy utilized when proximity-seeking behavior has been punished, leading individuals to appraise closeness as threatening and defensively inflate positive self-views while actively inhibiting distressing emotions like fear and sadness,. This suppression is resource-intensive, however, and breaks down under high cognitive load or extreme, chronic stress, causing suppressed thoughts and negative self-traits to resurface. In contrast, anxious hyperactivation arises from inconsistent or intrusive caregiving, leading to a heightened fear of abandonment, rejection sensitivity, an ambivalent approach-avoidance conflict, and the intensification of negative emotions to ensure an attachment figure’s attention,. Finally, the chapter connects attachment theory to optimal functioning and the positive psychology movement, emphasizing that a strong sense of attachment security is a basic inner resource,. This security triggers the broaden and build cycle of attachment security by attenuating defensive strategies (such as intergroup biases or the need for self-enhancement), thereby freeing up mental resources for growth-oriented activities,. Securely attached individuals exhibit qualities described by humanistic psychologists, such as resilience, optimism, cognitive openness, self-acceptance, and the characteristics of a fully functioning person,.
