To address this issue, we employed a stochastic diffusion model analysis along with a novel thought-probe technique in task-switching paradigm. Across 152 participants, we found state anxiety was linked to higher switch costs in nondecision time but not drift rate parameter of diffusion model, which indicates that the locus of task-switching impairment in anxious individuals is pertinent to the efficiency …
