ABSTRACT
While interest grows in investigating sensory processing sensitivity (SPS), few studies have employed objective behavioural measures to directly explore the underlying attentional processing. The present study utilised two modified versions of the Emotional Attention Networks Test Integration (E-ANTI) to investigate whether and how emotion interacts with three attentional networks associated with SPS when emotion information was target-irrelevant (Experiment 1) and target-relevant (Experiment 2), respectively. Both experiments involved four manipulated within-subject factors: Signal (tone vs. no-tone), Cue Validity (valid vs. invalid), Flanker Congruency (congruent vs. incongruent), and Emotion (fearful vs. happy). Linear mixed models were employed, and three attentional networks were successfully captured in both experiments. In Experiment 1, we observed that as SPS increased, the difference in reaction time between valid and invalid cue conditions decreased, especially in incongruent trials. Participants rated fearful faces as more arousing than happy faces as SPS increased. In Experiment 2, we found that slow responding to fearful faces reduced as SPS increased, particularly in incongruent trials. The observed effects related to SPS in both experiments were particularly pronounced in incongruent conditions, suggesting that SPS may modulate attentional processes in high-conflict situations. Overall, higher SPS may be associated with increased cautiousness in conflict contexts.
