When the Feeling Persists but the Image Changes: Affect-Mediated Content Transformation and Downstream Cognitive Effects in Interpersonal Contexts

Interpersonal psychological influence is commonly conceptualised in terms of shared emotion, content-linked memory, secondary traumatic stress, co-rumination, or changes in beliefs and behaviour. These frameworks do not fully address another possibility: emotionally intense communication may evoke an affective state in a listener that persists or is later reactivated. In contrast, the listener’s own associative processes generate new mental content that is semantically distant from the source yet affectively congruent with the induced state. This article proposes affect-mediated content transformation (AMCT) as a testable conceptual model of that process. The framework originated as an inductive hypothesis prompted by the observation of a single naturally occurring individual experience; the original observation is not reported or treated as evidence and serves only as a source for hypothesis generation. AMCT refers specifically to a proposed content-transformation pathway: interpersonal affect induction, persistent or delayed affective activation, endogenous generation of novel content, and, in some individuals, ego-dystonic appraisal and maintenance through monitoring or control. The broader framework also introduces a separate functional extension in which affective activation may be associated with transient changes in attention, working-memory performance, or the encoding of routine events. This functional extension does not constitute content transformation and is therefore analysed separately from core AMCT. The article integrates research on interpersonal affective influence, co-rumination, verbal threat learning, mental imagery, acute stress and executive function, unwanted intrusive thoughts, and cognitive models of obsessions. It proposes empirically testable hypotheses, experimental and longitudinal designs, and explicit comparisons with competing explanations. The framework does not posit direct interpersonal transmission of trauma, obsessive-compulsive disorder, intrusive thoughts, or cognitive lapses, nor does it interpret low self-reported distress as evidence of unobserved activation. The complete AMCT sequence remains unestablished; existing evidence supports only its component processes. Particular emphasis is therefore placed on prospective measurement, temporal alignment, medical and situational confounding, independent validation, and protection against retrospective overinterpretation.
