Attention Bias Variability

Recent years have seen increasing interest in the construct of attention bias variability (AB-Var). However, little is known about the cognitive underpinnings of this construct, with some research suggesting that AB-Var may represent an artefact of other processes. The present study examined the underlying role of attention control and response time variability in explaining the relationship between anxiety and two commonly computed measures of AB-Var (‘moving average’ and ‘trial-level bias score’ measures). Participants (final n=195) completed measures of anxiety symptomatology, antisaccade performance (attention control), a stand-alone measure of response-time variability, and a probe task measure of attentional bias. Both measures of AB-Var were significantly associated with anxiety, response time variability, and attention control. Attention control was the single significant statistical mediator of the relationship between anxiety and the trial-level bias score measure of AB-Var. Neither response time variability nor attention control significantly mediated the relationship between anxiety and the moving average measure of AB-Var. No evidence was found for the mediating role of response time variability. The present findings suggest that the relationships observed between anxiety and the trial-level bias score measure of AB-Var in particular may be attributable to the over-arching role of attention control.
