Anxiety-linked impairment in the ability to recode stimuli.

It has been proposed that elevated trait anxiety is associated with deficits in cognitive flexibility, which is required to enable people to switch between different ways of classifying information. Recent research has focused on a particular facet of cognitive flexibility that may be specifically impaired in high trait anxious individuals. This concerns the ability to recode stimulus information that has initially been categorized in terms of 1 stimulus dimension, in terms of an alternative dimension. However, limitations in previously employed assessment methodologies compromise the capacity to draw firm conclusions from prior research investigating this hypothesis. Across 2 studies we developed and delivered a novel stimulus information recoding assessment task to a sample of individuals who varied in trait anxiety, to test the hypothesis that elevated trait anxiety is specifically associated with a deficit in the ability to recode information that has already been classified. Across both studies we found evidence to support this hypothesis. The theoretical and practical implications of these findings are discussed.
