Defensive self-presentation style is associated with reduced prepulse inhibition
چکیده انگلیسی

Prepulse inhibition (PPI) of the startle response is a cross-species measure of sensorimotor gating that provides a valuable tool for assessing the capacity to effectively screen out irrelevant sensory input. Accumulating evidence suggests that PPI deficits may correlate with impairments in social cognition, i.e. the ability to construct representation about others, oneself and the relations between others and oneself. Social cognition deficits are commonly encountered within the framework of psychiatric disorders. In this study 113 healthy volunteers completed psychopyhsiological measures of sensorimotor gating (PPI) and social self-presentation style (the Concern for Appropriate (CAS) and the Revised Self-Monitoring (RSMS) scales). CAS measures a defensive and fearful social approach aiming at avoiding social threats; RSMS measures an active and flexible social approach aiming at gaining power and status. Analyses revealed an inverse correlation between PPI at the 120 ms prepulse-to-pulse interval and total CAS scores (r = −0.19, p = 0.04), as well as with the Attention to Social Comparison Information (ASCI) subscale of the CAS (r = −0.23, p = 0.01). These findings suggest that reduced PPI may contribute to the tendency to adopt a defensive and fearful “getting along” social approach. This study is, to our knowledge, the first to assess the relationship between sensorimotor gating and self-presentational style in humans. Its findings suggest that very basic perceptual deficits that can be assessed using the PPI paradigm, may reflect information processing abnormalities that impact negatively upon the perception of complex social interactions.
