120
If the automatic habits are the appropriate, ___ will increase our performance, and if they are not it will reduce it.
anxiety
121
If ___ shifts focus from the goal-directed attentional system to the stimulus driven attentional system, it means anxiety may increase the odds irrelevant stimuli interfere with our ability to the task.
anxiety
122
Has 3 main functions:
