The time between shocks or the interval and the time away from shocks produced by responses or the interval are two aspects of escape and avoidance.

Shock-shock, response-shock

Explanation:

Escape and avoidance are the two terms that are used in classical conditioning. The difference between these two terms are used in conditioning and the presentation of these terms are before the aversion stimulus
