The revised Reinforcement Sensitivity Theory: electrocortical correlates of threatening faces at different distances.

Abstract

The main purpose of the present work was to evaluate individual differences in the perception of threatening stimuli at different distances. Under the approach of the revised Reinforcement Sensitivity Theory, we analysed how the different traits of personality react to angry and neutral faces in an Augmented Reality environment using a Visual Oddball paradigm. We found that the N2 component is the most prone to point out the differences especially for Fight and Freeze subjects, showing how they use more frontal processes in the differentiation between near and far stimuli. This results could be explained by the neuroanatomical differentiation proposed by McNaughton and Corr in the 2004
