Abstract. A considerable number of behavioral and neuroscientific studies on insight problem solving have revealed behavioral and neural correlates of the dynamic insight process; however, somatic correlates, particularly somatic precursors of creative insight, remain undetermined. To characterize the somatic precursor of spontaneous insight, 22 healthy volunteers were recruited to solve the compound remote associate (CRA) task in which a problem can be solved by either an insight or an analytic strategy. The participants’ peripheral nervous activities, particularly electrodermal and cardiovascular responses, were continuously monitored and separately measured. The results revealed a greater skin conductance magnitude for insight trials than for non-insight trials in the 4-s time span prior to problem solutions and two marginally significant correlations between pre-solution heart rate variability (HRV) and the solution time of insight trials. Our findings provide the first direct evidence that spontaneous insight in problem solving is a somatically peculiar process that is distinct from the stepwise process of analytic problem solving and can be represented by a special somatic precursor, which is a stronger pre-solution electrodermal activity and a correlation between problem solution time and certain HRV indicators such as the root mean square successive difference (RMSSD).

Affective Consequences

Background and Objectives: Social interactions involving personal disclosures are ubiquitous in social life and have important relational implications. A large body of research has documented positive outcomes from fruitful social interactions with amicable individuals, but less is known about how self-disclosing interactions with inimical interaction partners impacts individuals. Design and Methods: Participants engaged in an immersive social interaction task with a confederate (thought to be another participant) trained to behave amicably (Fast Friends) or inimically (Fast Foes). Cardiovascular responses were measured during the interaction and behavioral displays coded. Participants also reported on their subjective experiences of the interaction. Results: Participants assigned to interact in the Fast Foes condition reported more negative affect and threat appraisals, displayed more negative behaviors (i.e., agitation and anxiety), and exhibited physiological threat responses (and lower cardiac output in particular) compared to participants assigned to the Fast Friends condition. Conclusions: The novel paradigm demonstrates differential stress and affective outcomes between positive and negative self-disclosure situations across multiple channels, providing a more nuanced understanding of the processes associated with disclosing information about the self in social contexts.
