사회불안 성향자의 분노 얼굴에 대한 크기지각 편향 연구

초록

This study investigated whether negative information-processing bias appears in perceptual processes and high order cognitive processes in individuals with social anxiety. To measure the size perceptual bias of individuals with social anxiety, a high-social anxiety (HSA; n=20) and low-social anxiety (LSA; n=22) group were presented happy, angry and neutral facial expressions and asked to choose a circle similar in size to the target face. The HSA group perceived the angry face as being significantly larger than the LSA group, while there were no significant differences in size perception between happy and neutral facial expressions. The results also revealed differences in size perception depending on the types of the facial expressions for each group. Specifically, the HSA group did not show differences in the patterns of size perception among facial expressions, while the LSA group smaller perceived significantly angry or neutral faces than happy faces. These findings indicate that size perception by the HSA group is affected by negative emotions and that this group perceives more negative faces as large. Because they allocate more attention and have difficulty of attentional control on negative faces. These factors results in HSA individuals experiencing problems during social interactions with others.
