On the latency of object recognition and affect: Evidence from temporal order and simultaneity judgments.

Abstract

According to the semantic primacy hypothesis of emotion generation, stimuli must be semantically categorized to evoke emotions. This hypothesis was tested for the subjective component of emotions in four chronometric experiments in which the conscious recognition of emotion-eliciting objects and the onset of affect was timed using temporal order judgments (TOJs, Exp. 1a, 1b, and 3) and simultaneity judgments (SJs, Exp. 2). Participants viewed pictures that elicited pleasant or unpleasant feelings. At varying intervals before and after picture onset, a visual probe stimulus was presented. In separate blocks of trials, the participants judged when they recognized the object shown in the picture and noticed the feeling evoked by the picture: Before or after the probe (TOJs), or simultaneously/not simultaneously with the probe (SJs). Psychometric functions were fitted to the data of the individual participants to determine the point of subjective simultaneity (PSS) of the target events and the probe. In both tasks, the mean PSS of affect occurred significantly later than the PSS of object recognition, with an average delay of about 120 ms. A positive lag between object recognition and affect was found for nearly all participants and pictures. In addition, the latencies of object recognition and affect were positively correlated. The found temporal order of object recognition and affect is consistent with the findings of previous studies using speeded reaction time tasks. Implications of the findings for the cognition-emotion debate and for bodily feedback theories of emotional experience are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
