The technique used by Meeku's teacher is Positive reinforcement. This is a behavioral technique where a desired behavior is followed by a rewarding stimulus (in this case, applause and positive attention). Over time, Meeku learned to associate attending class and completing homework with positive outcomes, which led to a change in his behavior.
- Aversion therapy is used to reduce undesirable behaviors by associating them with unpleasant stimuli, which is not applicable here.
-Token economy involves providing tokens as rewards for desired behaviors, but it is not specifically mentioned in this scenario.
- Systematic desensitization is typically used for reducing anxiety, not relevant in this case.
Thus, the correct answer is Positive reinforcement.
