Effects of Social Anxiety on Nonverbal Accuracy and Response Time I: Facial Expressions

Cognitive models of social anxiety provide a basis for predicting that the ability to process nonverbal information accurately and quickly should be impaired during the experience of state anxiety. To test this hypothesis, we assigned participants to threatening and non-threatening conditions and asked them to label the emotions expressed in a series of faces. It was predicted that social anxiety would be positively associated with errors and response times in threatening conditions, but not in a non-threatening condition. It was also predicted that high social anxiety would be associated with more errors and longer response times when identifying similar expressions such as sadness, anger, and fear. The results indicate that social anxiety was not associated with errors in identifying facial expressions of emotion, regardless of the level of state anxiety experienced. However, social anxiety scores were found to be significantly related to response times to identify facial expressions, but the relationship varied depending on the level of state anxiety experienced. Methodological and theoretical implications of using response time data when assessing nonverbal ability are discussed.
