An adult with intellectual and developmental disabilities gets up frequently during the night to talk and check on awake overnight staff in the group home. When an extinction procedure is implemented and staff no longer talk with the individual during the night, the individual gets up even more frequently for the first three nights. This secondary effect of extinction is referred to as a/an:
a) extinction-induced variability.
b) behavioral resurgence.
c) extinction burst.
d) spontaneous recovery.
