Describe Zajonc's drive theory of social facilitation

What will be an ideal response?

Answer:
The presence of other persons increases an individual's physiological arousal. This, in turn, increases the probability that the individual will perform dominant responses. If the individual is highly skilled in a well-learned task, the dominant responses will be correct, and performance will improve. If the individual is unskilled in a task, the dominant responses are more likely to be incorrect ones, and performance will suffer.
