Discussion

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: A reinforcer is something that encourages or promotes a behaviour. The use of positive reinforcement involves adding something to a situation to encourage a behaviour.
Reason R: For example, if a child is given a cookie for cleaning a room, the addition of cookie makes cleaning more likely in the future.

In the light of the above statements, choose the most appropriate answer from the options given below:

  • A.Both A and R are correct and R is the correct explanation of A.
  • B.Both A and R are correct but R is not the correct explanation of A.
  • C.A is correct but R is not correct.
  • D.A is not correct but R is correct.

Answer: A

The answer is Both A and R are correct and R is the correct explanation of A.

In operant conditioning a reinforcer is anything that strengthens a behaviour, and positive reinforcement means adding something pleasant after the behaviour so that it is more likely to happen again.

The Reason gives the classic example: a cookie (something added) given for cleaning the room makes cleaning more likely in future. Since it illustrates exactly the principle stated in A, the key treats R as its explanation.
