Distractibility as a precursor to anxiety: Preexisting attentional control deficits predict subsequent autonomic arousal during anxiety

Low attentional control (AC) and high anxiety are closely linked. Researchers often presume that high anxiety reduces AC; however, the reverse causal possibility - that low AC increases anxiety - is equally plausible. We addressed this question in people with elevated trait anxiety by evaluating the temporal precedence of the AC-anxiety association. We tested whether autonomic arousal (electrodermal activity) and subjective anxiety elicited by an anxiety induction were associated more strongly with AC measured either pre-induction (N=40) or post-induction (N=38). Low AC was indexed by distractibility during a visual search task requiring attentional inhibition of emotionally neutral distractors. Higher distractibility predicted higher autonomic activation but not higher increases in self-reported anxiety. Critically, this AC-anxiety association occurred for pre-induction but not post-induction AC. The results suggest that low AC may heighten subsequent anxious arousal. By implication, treatment interventions should specifically enhance AC to alleviate anxiety. (C) 2015 Elsevier B.V. All rights reserved.
