Competition between endogenous and exogenous attention to nonemotional stimuli in social anxiety.
This study investigated whether impaired endogenous attention and enhanced exogenous attention for the processing of nonemotional stimuli were observed in individuals with high social anxiety. In each trial, participants were presented with an endogenous cue at a center, followed by exogenous cues at peripheral locations; subsequently, nonemotional masked targets were presented wherein the subjects were asked to distinguish between the targets. The accuracy rates were influenced by social anxiety only in exogenous conditions. Individuals with high social anxiety exhibited higher accuracy in the valid condition than in the invalid condition of exogenous attention, whereas individuals with low social anxiety displayed uniform accuracy rates in valid, neutral, and invalid conditions. The validity effects in individuals with high social anxiety did not diminish when controlling for trait and state anxiety and depression. The results suggest that individuals with high social anxiety have an enhanced exogenous attentional system and that they are attracted to salient stimuli regardless of emotionality.
