Alternatively, the cycle may begin with the cognitive component. For example, 
before giving a presentation, you may tell yourself that you are going to lose your train 
of thought and that others will notice how uncomfortable you are. You imagine that the 
others will interpret your discomfort as a sign of weakness (cognitive component). As 
you continue to dwell on these anxious thoughts, you notice your face beginning to feel 
ﬂushed and your heart rate increasing (physical component). Finally, you make a decision 
to read your presentation word for word to be sure that your anxiety doesn’t cause you 
to lose your place during the presentation (behavioral component).
