To better understand the mechanisms underlying preferential processing of affective stimuli (i.e., affective attention), it is useful to ask which appraisal dimensions characterize stimuli that capture affective attention. Viewed from such appraisal perspective, most accounts of affective attention predict that the appraisal of goal relevance (i.e. the overall relevance of a stimulus/event to one's current goals) should attract attention whereas some accounts also implicate the appraisal of goal congruence (i.e. the value of the stimulus with respect to these goals). We compared these accounts by investigating independent effects of goal relevance and goal congruence on attention capture operationalized through pupil dilation. Forty-seven participants completed a modified Monetary Incentive Delay task (MID) where they sought to maximize the amount of chocolate received at the end of the experiment, pupil data from forty-two participants were used in the final analysis. Implicating attention capture by goal relevance, we found that pupil size was increased by all win- and loss-related compared to neutral stimuli and by materialized wins and losses compared to non-materialized ones. By contrast, we did not find pupil dilation effects of goal congruence across three different operationalizations of this appraisal dimension. These findings suggest that goal congruence appraisal may not contribute to the aspects of affective attention reflected in pupil dilation over and above goal relevance appraisal.
