autonomic nervous system
An interpretation bias in social anxiety, which socially anxious individuals regard ambiguous socialsituations as negative, is confirmed in many studies. Though the previous studies discussed mainly verbal information,non-verbal information is also an important measure to understand others' emotion. Therefore misinterpretationfor non-verbal information may elicit various problems in interpersonal situations. The present studyaimed to investigate whether interpretation bias occurred in also non-verbal information. Participants were 32female undergraduate students, who were divided in to low social anxiety group(N=20) and high social anxietygroup(N=18). Participants made speech about self-related theme and non-related one for 5 minutes. While shemade a speech about one of themes, the interviewer who sat on the front of her acted ambiguous actions.Participants evaluated those actions after a speech. The results were as follows. Low social anxiety group paidattention to ambiguous actions more than high social anxiety group. High social anxiety group tended to attributea cause of these actions to self regardless of themes of speech. These results showed that interpretationbias occurred in also non-verbal information.
