摘要

Interpretation bias plays an important role in maintaining social anxiety. In the current study, we investigated how socially anxious individuals process ambiguous expressions. Twenty-one high socially anxious (HSA) individuals and nineteen low socially anxious (LSA) individuals completed a judgment task in which they judged whether or not the label “happy” or “angry” used to describe the blended facial expression (from happy to angry) was appropriate or not, while their EEG was recorded. The results showed that, compared to the LSA group, the HSA group showed a larger P600 for ambiguous expressions in the “happy” label condition. These findings provide evidence for a negative bias in the processing of ambiguous expressions in individuals with high social anxiety.
