Action-orientation shields against primed cognitive conflict effects on effort-related cardiac response

Abstract

This article presents a quasi-experiment (N = 79 university students) testing whether individual differences in action-state orientation moderate primed cognitive conflict's effects on sympathetically mediated cardiac response during task performance reflecting effort. Action control theory posits that action-oriented individuals are less receptive to distracting affective stimuli during goal pursuit than state-oriented individuals because action-orientation is related to higher volitional skills. Therefore, we expected that action-oriented individuals should be shielded against conflict primes' effect on effort-related responses in the cardiovascular system. By contrast, state-oriented individuals should be more sensitive to irrelevant negative affective stimulation and therefore mobilize higher resources under such conditions. Responses of the cardiac pre-ejection period (PEP) during a moderately difficult short-term memory task corroborated these predictions. The present findings provide the first evidence that individual differences in action-state orientation indeed moderate previously demonstrated cognitive conflict priming effects on effort-related cardiac response and extend recent findings on action shielding.
