Which statement best describes an evocative effect?

Explanation:
An evocative effect is when a stimulus, because of its history of being paired with reinforcement, increases the likelihood that a behavior will occur. In other words, the presence of the stimulus makes the response more probable because that response has previously produced a positive outcome in its presence. For example, if a bell has repeatedly signaled food delivery, the bell will evoke more lever-pressing since it’s come to indicate reinforcement. This is why the statement about increasing the probability of a response that leads to a positive outcome best captures the evocative effect.
