Threat and uncertainty in the face of perceptual decision-making in anxiety.

Anxiety is defined as an anticipatory response to uncertain, future threats. It is unknown how anticipatory information regarding uncertainty about upcoming threatening and neutral stimuli impacts attention and perception in anxiety. Individuals with and without anxiety disorders performed two perceptual decision-making tasks in which they used threat or neutral prestimulus cues to discriminate between subsequent threatening and neutral faces. In one task, cues provided no probability information (high uncertainty). In the other, cues indicated a high probability of encountering threatening or neutral faces (low uncertainty). Under high uncertainty only, anxious apprehension was associated with worse discrimination between threatening versus neutral faces after threat cues. Additionally, anxious arousal was associated with worse discrimination after neutral cues in individuals with anxiety disorders. These findings will advance the field by spurring the development of more comprehensive and ecologically valid models in which anticipatory top–down factors influence threat perception in anxiety.
