Interpersonal Self-support And Attentional Bias For The Faces Of Different Characteristics:An ERP Study

Personality is the tendency of individual behavior on the internal. Therefore, in theory, the personality can also affect an individual’s cognitive behavioral. Inspired by this view, personality and cognitive bias are of concerned. Accordingly this some people also proposed trait consistency assumption.That is, individuals will tend to choose to match the information with his own personality when they encode information of the outside world perceptually. However,many scholars in the past focus their attention on the personality factor that can lead to or strengthen of some kind of cognitive bias.but some positive personality factors that can reduce the adverse cognitive bias were not concerned enough. Positive personality is generally considered better to help individuals to solve Practical Problem, to adapt to the environment.So positive personality may have positive cognitive function, an important manifestation of which is that it can help individuals to improve the negative cognitive bias. Self-support Personality is viewed as an excellent personality factor in traditional Chinese culture and hypothesized as a health personality, and interpersonal self-reliance is an important component of self-personality. Therefore, we believe that interpersonal self-reliance may also have positive cognitive function that can help individuals to reduce the adverse cognitive bias.In this study,we investigate the attentional bias of different levels of interpersonal self-reliance groups.In experiment l,we mainly use emotion Stroop paradigm to study the interference of attention in both high and low group. When three additional variables(depression, anxiety and extraversion) were controled, We found that that high group exists the attentional interference for the socially acceptable face and low group also exists the attentional interference not only for the socially acceptable face but also for the socially rejected face.In ERP result, at the advanced control processing stage, socially acceptable face induce larger P3 amplitude.For the low group, socially rejected face induce larger P3 amplitude only at FPZ.In experiment 2, we use cue-target paradigm to research the components of attentional bias at two groups. Through behavior result, we can found that high group have more difficulties in disengaging attention away from socially acceptable face.For the low group, the RT of socially rejected face are significantly longer than socially acceptable face, but it has no difference with neutral face. In ERP result,only under invalid cue condition, socially acceptable face induce larger P3 amplitude for high group and socially rejected face and socially rejected face induce larger P3 latency for low group.
