Answer:
A). Harrison is on a fixed-interval schedule of reinforcement.
Explanation:
'Fixed-interval schedule of reinforcement' is demonstrated as the specified schedule or plan of reinforcement in which the rewards or punishments are rewarded for a response only after a fixed interlude of time.
As per the question, the above statement presented in option A asserts a true claim that 'Harrison is on a fixed-interval schedule of reinforcement' which implies that his behavior/action was rewarded after a specific period of time(after five minutes). The chief aim of such reinforcement technique is to improve the impact and efficacy of the positive behavior through rewarding after a specified time period and weaken the negative response or behavior more constructively. Therefore, option A is the correct answer.
