Individual differences in action-state orientation moderate task difficulty effects on effort-related cardiac response.

A quasi experiment (N = 100 university students) tested whether individual differences in action-state orientation moderate task difficulty effects on resource mobilization assessed as cardiovascular response. According to action control theory, action-oriented individuals have higher self-regulation capacities in demanding situations than state-oriented persons. Action-orientated individuals should also self-generate positive affect in face of obstacles. Therefore, drawing on Wright's (1998) ability extension of motivational intensity theory and research on affective influences on effort-related cardiovascular response, we expected that action-orientation should lead to stronger effort-related cardiovascular responses in a difficult task, while state-orientation should do so in an easy task. Reactivity of cardiac pre-ejection period (PEP) during performance on a short-term memory task corroborated this hypothesis. The present findings provide the first evidence of a link between action-state orientation and effort-related responses in the cardiovascular system.
