Positive reinforcement classroom praise – UGC NET Question

In behaviourist terms, positive reinforcement involves presenting a rewarding stimulus after a desired response to strengthen that behaviour. Praising a student immediately after a correct answer is a classic example because the verbal appreciation serves as a reward. This tends to increase the likelihood of future correct responses. Consequently, the reinforcement described in the stem is positive reinforcement.

Option A:
Negative reinforcement involves removing an unpleasant stimulus when the desired behaviour occurs, such as reducing homework for consistent good performance. It is not the same as giving praise or rewards. Since the stem mentions adding praise rather than removing something aversive, negative reinforcement is not the correct classification.

Option B:
Intermittent reinforcement concerns the schedule or frequency with which reinforcement is given, not whether it is positive or negative. Praise could be given intermittently or continuously. The question, however, focuses on the nature of the reinforcement itself, not its schedule.

Option C:
Positive reinforcement adds something pleasant—such as praise, tokens or privileges—immediately after the desired response. This strengthens the association between the behaviour and its consequences. Because the teacher’s praise is a pleasant stimulus following a correct response, this option correctly identifies the type of reinforcement.

Option D:
Punishment involves presenting an unpleasant stimulus or removing a pleasant one in order to reduce unwanted behaviour. Examples include scolding or detention for misbehaviour. Since the teacher in the stem is praising a correct response rather than discouraging behaviour, punishment is not involved.
