Malcom Gladwell, in Blink, "Emotion can also
start on the face. The face is not a secondary billboard for our internal feelings. It is an equal partner in the emotional process...At 175 (beats per minute of the heart), we begin to see an absolute breakdown of cognitive processing. The forebrain shuts down, and the mid-brain reaches up and hijacks the forebrain...Vision becomes even more restricted. Behavior becomes inappropriately aggressive." Therefore, rehearsal is key to success.
