Abstract

Theories of neuroticism emphasise its close potential link to punishment-reactivity processes, yet cognitive sources of evidence for this proposed processing basis are surprisingly scarce. The present two studies (N = 123) sought to rectify this important gap in the literature in terms of reactivity to error feedback. Study 1 found that individuals high in neuroticism were faster to switch behavioural responses following errors, whereas an opposite pattern was found among individuals low in neuroticism. Study 2 extended this error-reactivity perspective to the realm of behavioural decision making. Individuals high in neuroticism switched their behavioural predictions following error feedback, whereas this tendency was non-significant among individuals low in neuroticism. Together, the studies present novel, but theory-informed, cognitive paradigms for assessing punishment-reactivity processes, confirm neuroticism's link to such processes, and do so in the realms of both reaction time (Study 1) and behavioural predictions (Study 2). The discussion focuses on the utility of modelling punishment-reactivity processes in cognitive terms and highlights relevant directions for future research.
