Attentional control theory (ACT) suggests that anxiety impairs attentional control including inhibition and shifting. ACT also assumes that anxiety negatively affect processing efficiency (i.e., response latency) more than performance effectiveness (i.e., response accuracy). Moreover, increased cognitive load may worsen the adverse effects of anxiety on attentional control. Two studies using antisaccade paradigms were conducted to investigate the executive functions of inhibition and shifting and examine the effect of cognitive load on attentional control in individuals with subclinical social anxiety. Theoretical and practical implications of the two studies will be discussed.
