Intermittent reinforcement
A reinforcement schedule during which only some instances of a behavior are reinforced.
Internal validity
The extent to which an experiment strongly shows that changes in the dependent variable are a direct result of the independent variable and not the result of some other uncontrolled
Interobserver agreement (IOA)
A measurement of the degree to which two or more observers report the same values when observing and collecting data for the same behaviors/events.

Interresponse time (IRT)
A measurable duration of time that elapses between two consecutive instances of a response.
Intersubject direct replication
An experimental replication of a previous study in which the researcher exactly duplicates a previous study but uses different subjects from the original study.
Intrasubject direct replication
An experimental replication of a previous study in which the researcher exactly duplicates a previous study using the same subjects as the original study.
Intraverbal
An elementary verbal operant in which a speaker differentially responds to the verbal behavior of others that has a history of generalized conditioned reinforcement.
Intraverbal bidirectional naming (I-BiN)
Intraverbal relations that emerge from one previously acquired tact, intraverbal, listener response, direct observations, and combinations of verbal behaviors (e.g., when asked, “What do you sleep in?” the client responds,
Irreversibility
A behavior for which the effects of treatment cannot be undone. Therefore, it cannot return to a baseline level of responding when an independent variable is removed.
Lag schedule of reinforcement
A variation of basic intermittent schedules of reinforcement in which reinforcement is delivered for any response that differs in topography, sequence, etc., from a previously reinforced response.
