Event-related potentials when identifying or color-naming threatening schematic stimuli in spider phobic and non-phobic individuals

摘要

BackgroundPrevious studies revealed increased parietal late positive potentials (LPPs) in response to spider pictures in spider phobic individuals. This study searched for basic features of fear-relevant stimuli by investigating whether schematic spider images are sufficient to evoke differential behavioral as well as differential early and late ERP responses in spider phobic, social phobic (as a clinical control group), and non-phobic control participants.
