Sensory Processing Sensitivity (SPS) is a common, heritable, and evolutionarily conserved trait, describing inter-individual differences in responsiveness and a more cautious approach to novel stimuli. It is associated with increased activation of brain regions involved in awareness, integration of sensory information, and empathy during processing of emotional faces. Furthermore, SPS is related to better performance in a visual detection task. Even though SPS is conceptualized to be closely related to traits characterized by pausing before acting, no study to date has assessed the relation between SPS and inhibitory control in a behavioral inhibition task. The present study fills this gap by investigating how SPS influences individual performance on two different antisaccade paradigms including emotional face stimuli. In addition, we assessed self-reported mood, anxiety, and depressiveness. Results showed that SPS was related to faster processing speed on the emotional, but not the classic antisaccade paradigm. Moreover, SPS predicted inhibitory control speed above mood and depressiveness. Our results provide evidence that higher SPS participants show superior inhibitory abilities, especially during the processing of emotional stimuli. This is in line with earlier findings showing better performance in a visual detection task as well as increased brain activation during emotional face processing. |
