Alphonse is determining the effectiveness of a differential reinforcement of other behavior (DRO) procedure on decreasing his client’s tantrums. For every 10 minutes in which his client does not engage in tantrum behavior, they earn tokens. The amount of tokens varies based on the activity they are engaged in because the client appears to dislike some activities more than others. A week into implementing his DRO procedure, the client comes down with a cold. Despite this, Alphonse still sees an immediate decrease in tantrums and an increase in independent requests to take a break from his client. Which of the following is most likely to be an extraneous variable in this scenario?
