Differential encoding of affective and nonaffective content information in trait anxiety

Abstract

The relative encoding of affective and nonaffective content information in high and low trait anxious individuals was investigated. Experiment 1 (N = 35) found that, compared to Low Anxiety participants, High Anxiety participants showed relatively greater speeding of affective semantic decisions compared to nonaffective content semantic decisions. Using a similarity rating paradigm, Experiments 2 (N = 51) and 3 (N = 100) found higher levels of trait anxiety were associated with a decreased use of content information when nonaffective information was less salient than affective information. Experiment 4 (N = 100) found higher levels of trait anxiety were associated with a complementary increased use of affective information when affective information was less salient than nonaffective information. Thus, it appears that trait anxiety may be associated with a bias to encode less salient information to a greater extent when it is relevant to affect, and to a lesser extent when it is not.
