"Attentional control theory focuses on anxiety and cognitive performance. The assumption of this theory is that the effects of anxiety on attentional control are key to understanding the relationship between anxiety and performance. In general, anxiety inhibits attentional control on a specific task by impairing processing efficiency. There are three functions associated with this theory. The inhibition function prevents stimuli unrelated to a task and responses from disruptin… " - Top down attentional control
