Which contingency makes it difficult for the learner to discriminate whether the next response will produce reinforcement?

• A. Interdisciplinary Contingency
• B. Indiscriminable Contingency
• C. Interdependent Group Contingency
• D. Instructional Setting

Answer: (B)

Discrimination of reinforcement contingencies depends on signals that tell the learner when a response will be reinforced. When the contingency is indiscriminable, reinforcement for a given behavior isn’t clearly signaled or predictable from one response to the next. The result is that the next response’s chance of being reinforced feels random, making it hard for the learner to tell which responses will pay off. This unpredictability keeps responding steady or even increases persistence, because reinforcement can occur intermittently without clear cues.

That’s why this option best fits the idea described. The other contingencies involve different organizational or instructional structures (across settings or groups, or simply the setting itself) and do not specifically capture the learner’s difficulty in predicting reinforcement for the next response.
