Time Perception & Physiological Arousal
Many tasks have an inherent element of timing. Comedy, dancing, baseball, etc. However, we've known for years that physiological arousal modulates our sense of timing. During periods of high arousal, time seems to go by slower. Understanding how our sense of timing changes as a function of arousal, then, would be important in understanding the optimal level of arousal.
