Jack finds it extremely difficult to pull himself away from the blackjack table. he keeps thinking he will win the next hand, which will enable him to break even. jack is reinforced on a _____ schedule.
Jack is being reinforced on a variable-ratio schedule. The main identifiable characteristic of this schedule is that it rewards after an unpredictable amount of responses, meaning that people (especially in the sense of gambling) are drawn to it almost immediately because of the uncertainty if they will win or not. This means that variable-ratio schedules contrast with fixed-ratio, since in a fixed-ratio schedule a reward is received after a certain number of responses.
