An FI/LH Is Similar to a Simple FI Schedule, Procedurally

An FI/LH is similar to a simple FI schedule, procedurally, in that in both FI and FI/LH:

A) long pauses occur at the beginning of the interval followed by steady responding
B) reinforcement remains available for only a limited period of time
C) reinforcement is programmed to occur after the first response after a fixed period of time
D) reinforcement occurs after a certain number of responses are emitted
