Meeku was pulled up by his teachers for missing classes to play cricket during school hours. To modify his behaviour, Meeku's class-teacher applauded him every time his home work was submitted or when he answered in class. Gradually Meeku started enjoying his teacher's class and stopped missing it. Which behavioural technique did the class teacher use?

Positive reinforcement

The correct answer is Option (3) → Positive reinforcement

Positive reinforcement is a behavior modification technique in which a desirable stimulus (like praise or reward) is given after a desired behavior, increasing the likelihood of that behavior being repeated.

In Meeku's case:

• The teacher applauded (gave positive feedback) when he submitted homework or participated in class.

• As a result, Meeku’s positive behavior increased, and he stopped missing class.

This is a classic example of positive reinforcement being used effectively to shape desirable behavior.
