Harold catches fish throughout the day at unpredictable intervals. Which reinforcement schedule is this?a. variable interval b. variable ratio c. fixed interval d. fixed ratio

The correct answer to the question is

a. variable interval

Step-by-step explanation:

In a variable interval, the time at which reinforcement or reward is gained occurs at an unpredictable time. That is the animal gets a reinforcement on the grounds of an unpredictable time period.

An example of a variable interval is the catching of fish whereby the fisher catches fishes at an unpredictable time throughout the day.

The result of a variable interval is a controlled but stable response rate. In the case in the question, constant monitoring of the fishing device is important
