Internal Working Model

The internal working model (IWM) stands as one of the pivotal conceptual bridges between Bowlby’s attachment theory and the broader depth-psychological tradition. Across the corpus, the term designates a dual representational structure — an environmental model mapping the world and an organismal model mapping the self-in-relation — constructed from early dyadic experience and carrying significant affective freight alongside its cognitive architecture. Bowlby himself, as glossed in the secondary literature, drew on Craik’s cognitive psychology to ground the concept, yet insisted that these mental maps are not neutral schemata: they are shaped by defensive exclusion, laden with hedonic tone, and capable of distorting subsequent relational experience in ways that resist disconfirmation. Flores situates IWM within a broader matrix of internalization theories, aligning it with Piaget’s representational theory and intersubjectivity models while distinguishing it from classical object-relations accounts. Schore extends the concept neurobiologically, locating the earliest IWMs in right-hemisphere orbitofrontal circuitry and arguing that affective regulatory transactions with the caregiver literally program the neural substrate of these models. Siegel integrates IWM with memory science, describing it as a form of implicit mental model functioning as a relational script. The central tension in the corpus runs between cognitive-representational accounts (Bowlby, Siegel) and neurobiological-affective accounts (Schore), with Flores mediating through clinical application. What unites these voices is the conviction that IWMs are not merely cognitive records but active templates governing self-worth, relational expectation, and the capacity for affect regulation across the lifespan.

A securely attached child will store an internal working model of a responsive, loving, reliable care-giver, and of a self that is worthy of love and attention, and will bring these assumptions to bear on all other relationships.

This passage articulates the canonical formulation of IWM as a paired representational structure encoding both attachment-figure reliability and self-worth, which then governs expectations across subsequent relationships.

Bowlby saw higher animals as needing a map or model of the world in the brain, if they are successfully to predict, control and manipulate their environment. In Bowlby’s version humans have two such models, an ‘environmental’ model, telling us about the world, and an ‘organismal’ model, telling us about ourselves in relation to the world.

This glossary entry provides the foundational cognitive-psychological grounding of IWM as a dual cartography of world and self-in-relation, built from experience and subject to defensive modification.

An ‘internal working model of attachment’ is a form of mental model or schema. It is postulated that children can use a form of remembering called ‘evocative’ memory by the age of eighteen months to bring an image of an attachment figure forward in their minds.

Siegel integrates IWM with developmental memory science, linking the concept to evocative and implicit memory systems and describing it as a multisensory, script-like blueprint for interpersonal expectation.

Bowlby’s internal working model (IWM) is a representative model of internalization highly compatible with Piaget’s theory of representation and shares some similarities to object relations’ description of internalized self and object representations.

Flores positions IWM within a cross-theoretical landscape, distinguishing it from classical object-relations internalization while aligning it with intersubjectivity theory’s emphasis on the mutually constructed interpersonal field.

It is helpful to think of all interpersonal interactions as operating on two levels. There are the observable interchanges occurring between individuals in the external world, and the internal exchanges of self and object representations occurring within each person’s internal working model.

This passage theorizes psychotherapy as a dual-level process in which external behavioral interaction simultaneously modifies internal working models, making structural intrapsychic change the criterion of durable treatment outcome.

The Regulatory Function of Early Internal Working Models… The Affect Regulating Functions of Inceptive Right Hemisphere Internal Working Models

Schore’s chapter architecture explicitly assigns IWMs a regulatory neurobiological function, locating their earliest formation in right-hemisphere limbic circuitry and treating them as affect-regulating structures rather than merely cognitive maps.

The core of the earliest indelible internalized models of the self in relationship with an emotionally significant other, the substratum of self-identity, contains an expectation, a bias, that the primary attachment object will or will not remain available and accessible at times of hypo- or hyperstimulating affective stress.

Schore argues that the neurobiological substrate of IWM encodes an affective expectancy bias — availability versus unavailability of the attachment figure under stress — establishing the physiological foundation of security or insecurity.

Attachment, anxiety, internal working models… Around 7 months the baby will begin to show ‘stranger anxiety’, becoming silent and clingy in the presence of an unknown person.

This passage situates the developmental emergence of IWMs within the onset of attachment proper at six months, linking their formation to the cascade of cognitive, locomotor, and social changes that inaugurate goal-corrected attachment behavior.

These internal representations contain a strong affective component and are used as interaction routines that guide interpersonal behavior.

Schore synthesizes convergent formulations from affect theory, developmental psychoanalysis, and social psychology to characterize IWM-analogous structures as affectively saturated interaction routines that organize interpersonal conduct.

When a woman manages either to retain or to regain access to such unhappy memories and reprocess them in such a way that she can come to terms with them, she is found to be no less able to respond to her child’s attachment behaviour so that he develops a secure attachment to her.

Bowlby demonstrates the clinical relevance of IWM revision, showing that therapeutic reprocessing of adverse early memories can interrupt the intergenerational transmission of insecure attachment patterns.

Dyadic, external psychobiological arousal regulation may allow for the creation of complex, internal, affect-laden abstract representations of the child’s interaction with the mother.

This passage provides the neurobiological mechanism by which dyadic arousal regulation during the practicing period generates the affect-laden internal representations that constitute early IWMs.
