The principal finding in Reynolds’s (1975) experiment with pigeons and a yoked experimental design was that
a. ratio schedules produce greater resistance to extinction than interval schedules do.
b. pauses following reinforcement are longer with ratio schedules than interval schedules
c. VR schedules produce higher rates of responding than VI schedules do.
d. Both FI and FR schedules produce a scalloped response pattern in the cumulative record.
c. VR schedules produce higher rates of responding than VI schedules do.
Answer feedback: Reynolds used the yoked experimental design in order to equate rates of reinforcement and showed that VR schedules produced higher rates of responding than VI schedules did. The scalloped pattern of responding is associated with FI schedules of reinforcement.
