Examining ERP and Cognitive Measures of Response Inhibition in Hypersensitive Individuals

Abstract

The aim of this research is to explore how response inhibition performance, as measured by the stop-signal task (SST), is influenced by sensory sensitivity assessed through the Multi-Modal Evaluation of Sensory Sensitivity (MESSY) questionnaire. It is additionally examined whether cognitive control mechanisms, particularly those reflected in event-related potentials such as the P3 component, are altered in individuals with heightened sensory sensitivity. Electrophysiological (EEG) and behavioral data, including Stop-Signal Reaction Time (SSRT) and P3 amplitude, were used to examine variations in P3 amplitude, SSRTs and the link to MESSY score outcomes among 47 participants. Regression analyses showed no statistically significant relationship between SSRTs, P3 amplitude and MESSY scores (p > 0.05). Further research is required to clarify the role of sensory sensitivity in inhibitory control within neurotypical populations.
