Within the depth-psychology corpus, 'interaction' operates across radically different registers—biological, social, neurological, therapeutic, and evolutionary—and no single authority owns the term. Gallagher deploys it to anchor an 'interaction theory' of intersubjectivity that contests theory-of-mind cognitivism, grounding social understanding in embodied, pre-reflective engagement rather than metarepresentation. Thompson draws on the replicator/interactor distinction from evolutionary theory to interrogate the relation between organisms and their selective environments. Schore situates dyadic mother-infant interaction at the origin of affect regulation and neural self-organization, making early relational exchange constitutive of the developing self. Levine and Dana treat therapeutic interaction as a somatic event regulated by the autonomic nervous system, where posture, gesture, and proximity are the medium of change. Lanius and colleagues situate gene-environment interaction at the nexus of psychiatric risk and resilience following early trauma. Yalom analyzes verbal interaction in group psychotherapy as the measurable index of group cohesion and therapeutic process. Klein identifies the interaction of internal and external danger-situations as a lifelong dynamic, not merely an infantile one. What unifies these diverse deployments is the conviction that interaction is never a neutral exchange: it is the site where structure is formed, disrupted, or restored—whether that structure is a cell membrane, a psyche, or a social group.

'replication' and 'interaction' are the two processes that make up evolution. Replication is the process whereby certain entities—the 'replicators'—are directly and accurately copied from one generation to the next... Interaction is what makes replication differential
Thompson articulates the replicator/interactor distinction as the foundational duality of evolutionary theory, positioning interaction as the environmental mediation that renders replication differential and thus drives selection.

Rather than understanding a deficit in metarepresentation as the cause of problems in social interaction, it seems just as feasible to understand a deficit in metarepresentation as the result of more primary problems in social interaction.
Gallagher reverses the standard theory-of-mind account of autism, arguing that failures of social interaction may be etiologically prior to metarepresentational deficits rather than caused by them.
Gallagher, Shaun, How the Body Shapes the Mind, 2005thesis
from the basic perceptual and emotional processes that are already at work in infancy, to a sophisticated interaction with other people... your human nature is expressed in intentional action and in interaction with others.
Gallagher concludes that embodied interaction with others is not incidental but constitutive of human nature, running from infant perception through the highest cognitive faculties.
Gallagher, Shaun, How the Body Shapes the Mind, 2005thesis
the interaction between external and internal danger-situations persists throughout life.
Klein argues that the interplay of internal fantasy-driven anxiety and external reality is not merely an infantile phenomenon but a permanent structural feature of psychological life.
Klein, Melanie, Envy and Gratitude and Other Works 1946-1963, 1957thesis
Early life stress (ELS) and abuse are the most commonly assessed environmental exposures in psychiatric G×E interaction studies, partly because of the strength of evidence that ELS plays a role in risk for multiple psychiatric disorders.
Lanius frames gene-environment interaction as the central explanatory model for how early life trauma translates into differential psychiatric risk and resilience.

Joy is the product of a mutual regulation of social exchange by both partners. Smiling back and forth is the prototypic example... Each partner then progressively escalates—kicking the other into higher orbit, so to speak.
Schore draws on Stern's infant research to demonstrate that early dyadic interaction is the crucible of affect regulation, with bidirectional escalation building the neurological scaffolding of emotional development.

Self-directed gestures significantly increased from play episode to still-face and decreased from still-face to the reunion episode... Other-directed gestures significantly decreased from play to still-face.
Infant gesture research operationalizes the self/other axis of interaction, showing how the presence or withdrawal of a responsive caregiver shifts the infant's behavioral economy between self-directed and other-directed action.

Gallagher's index entry for 'interaction theory' situates it as a distinct theoretical position spanning embodied inter-corporeality and intersubjectivity, occupying a substantial portion of his treatment of social cognition.

This additional interaction prevents the spontaneous and premature bonding of L particles produced within the membrane... 'chain-based bond inhibition'... bonding is inhibited to any free L particle which is in the immediate vicinity of another L particle which is doubly bonded.
Thompson's examination of autopoietic chemistry illustrates how molecular-level interactions—specifically inhibitory ones—are necessary for the structural integrity of self-organizing biological membranes.

Tape recordings of the second, sixth, tenth, twelfth, and sixteenth meetings were analyzed to classify the verbal interaction... The Hill Interaction Matrix method of scoring interaction was used.
Yalom employs the Hill Interaction Matrix as a systematic empirical instrument for measuring the quality and type of verbal interaction in group psychotherapy, linking measured interaction to therapeutic outcome.

the challenges described above... do not preclude the possibility of conducting meaningful and replicable G×E research on risk/resilience for psychiatric disorders.
Lanius maintains that despite methodological difficulties, gene-environment interaction research remains the viable framework for understanding psychiatric risk following early trauma.

Kratzer's RCT employs the statistical interaction term (group × time) as the primary index of differential treatment efficacy, here finding no significant site-by-group interaction and thereby supporting generalizability of bouldering psychotherapy effects.

infants can engage in other- and self-directed behaviors that involve both these action-oriented behaviors and simultaneously regulate them, and the control is found in limbic and other brain areas without any great involvement of cortical mechanisms.
The passage establishes that early social interaction is neurobiologically regulated subcortically before cortical mechanisms mature, underscoring the depth at which relational interaction shapes development.

The expressive qualities of people in my studios reciprocally interact with the level and quality of energy I bring to the space. How we do things and present ourselves to others often has a greater impact than what we say.
McNiff frames the therapeutic studio as a field of reciprocal energetic interaction where the therapist's somatic presence shapes the creative atmosphere as much as explicit technique.

each of these types of behaviour contributes in its own specific way to the survival either of the individual or his offspring... each one serves so vital a function that each of these types of behaviour is in some degree preprogrammed.
Bowlby's typology of biologically rooted behavioural systems implicitly frames attachment as a form of species-typical interaction, though the term 'interaction' itself is not foregrounded.

Farb uses the statistical interaction term to confirm the absence of confounding respiratory differences between mindfulness-trained and untrained participants, a methodological control rather than a conceptual argument about interaction.
