Trait anxiety reduces implicit expectancy during target spatial probability cueing.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Psychopathology

Background:

• Trait anxiety is linked to attentional biases toward threat and impaired attentional control, particularly in distractor inhibition.
• Anxiety's impact on expectation formation and subtle learning remains less understood.

Purpose of the Study:

• To investigate how trait anxiety modulates expectation formation based on task contingencies.
• To determine if anxiety affects subtle rule-based learning and predictive coding.

Main Methods:

• Participants completed a visual search task with color cues predicting target locations.
• Cue-target contingency awareness was assessed.
• Reaction times (RTs) for cue-valid versus cue-invalid trials were analyzed in relation to anxiety levels.

Main Results:

• Low anxious participants showed faster RTs for cue-valid trials, indicating learning of the contingency.
• High anxious participants did not show evidence of cueing, suggesting impaired learning.
• This effect was observed even without conscious awareness of the cue-target contingency.

Conclusions:

• Anxiety impairs subtle rule-based learning and the predictive coding of expectations.
• These findings suggest that attentional control deficits in anxiety extend to expectation formation.
• The lack of prediction in anxious individuals might reflect attentional deficits or a strategy for enhanced threat detection.
