Question

in order to get more audience participation, a radio show offers a prize to the first person to call in at the beginning of every hour. the show is using which of the following schedules of reinforcement?
a fixed ratio
b fixed interval
c variable ratio
d variable interval

Explanation:

The radio show offers a prize to the first caller at the beginning of every hour. A fixed interval schedule in operant conditioning is when reinforcement (here, the prize) occurs at consistent time intervals (every hour). Fixed ratio is based on a fixed number of responses, variable ratio on a variable number of responses, and variable interval on variable time intervals. Since the time between reinforcements (prize) is fixed (every hour), it's a fixed interval schedule.

Answer:

B. Fixed interval
