The Correct Option is A

Solution and Explanation

Step 1: Recall the goal. The question asks which technique does NOT increase a target behaviour.
Step 2: Define the terms. In operant conditioning, reinforcement increases behaviour and punishment decreases it. Positive reinforcement (a reward) adds something pleasant, increasing the behaviour. Negative reinforcement removes something unpleasant, which also increases the behaviour.
Step 3: Define punishment. Punishment, whether adding an aversive (positive punishment) or removing a pleasant stimulus (negative punishment), is designed to reduce or suppress a behaviour, not to increase it.
Step 4: Match to options. Reward and negative reinforcement both increase behaviour; operant conditioning is the broad framework under which reinforcement strengthens behaviour. Only punishment works to decrease behaviour.
Step 5: Therefore the exception is punishment.
Answer: Punishment.
