Assertion (A): Premack principle, based on Probability-Differential Hypothesis, states that the opportunity to engage in a frequently occurring activity can be used to reinforce less frequently activity.
Reason (R) : According to Probability-Differential Hypothesis, restricted access to a response makes that response reinforcing and excessive access to that response makes that response punishing.
Code :
This question examines the Premack principle and the Probability-Differential Hypothesis.
Assertion (A) states that the Premack principle uses a high-frequency activity to reinforce a low-frequency activity. This is a correct description of the Premack principle (also known as "Grandma's Law"). The principle posits that a more preferred activity (higher probability) can serve as a reinforcer for a less preferred activity (lower probability).
Therefore, Assertion (A) is TRUE.
Reason (R) claims that according to the Probability-Differential Hypothesis, restricted access makes a response reinforcing, and excessive access makes it punishing. This statement misrepresents the core concept of the Probability-Differential Hypothesis as it relates to the Premack principle. The hypothesis focuses on the relative baseline rates (probabilities) of activities influencing their reinforcing value, not on the effects of restriction or excess access directly making responses reinforcing or punishing in the way described.
Therefore, Reason (R) is FALSE.
Since Assertion (A) is true and Reason (R) is false, the correct option is the one that reflects this.
The correct code is that (A) is true, but (R) is false.
