Behavioral correlates of social anxiety.

High school students' scores on a paper-and-pencil test of social anxiety were correlated with talking, eye contact and gesturing behaviors during a 10-min vidotaped interview. Results showed that high anxious subjects talked less while listening to instruction. They also held the gaze for less total time and in bouts of shorter duration while they were talking;while they were listening, they were significantly more variable in their average bout duration. Within-group variability suggested that non-verbal behaviour should be analysed according to individual rather than group differences.
