What schedule of reinforcement should be used when initially using DRA with a new behavior?

a. Continuous reinforcement schedule (CRF)

b. Fixed interval: 2 (FI: 2)

c. Variable ratio: 1 (VR: 1)

d. Fixed ratio: 2 (FR: 2)

a. Continuous reinforcement schedule (CRF)

Explanation:

Under DRA (differential reinforcement alternative), behaviour that is an accepted alternative to problem behaviour is accepted and reinforced. This reinforcement frequency correctly falls under continuous reinforcement schedule (CRF) where behaviour is reinforced everytime there is a correct response. For example, if you were teaching a child to pronounce certain words correctly, you would reward the child everytime he got a pronunciation correct.
