The relationship between anxiety, mind wandering and task-switching: A diffusion model analysis

Although the negative impact of anxiety on task-switching has been documented, little is known about the extent or mechanisms of this impairment primarily because of the complex nature of task-switching and difficulty in probing the occurrence of worries within participants. To address this issue, w...
