an MO that establishes another stimulus as a reinforcer

future behavior increases because a stimulus is presented

a detectable change in the environment

behavior no longer produces attention that previously reinforced it

reinforcement is unavailable for a response in the presence of a stimulus

a momentary increase in the current frequency of behavior due to an MO

presenting one item at a time to assess preference

a preference assessment where the selected item is removed after each trial

reinforcement for the first response after a variable amount of time

recording antecedents, behavior, and consequences during observation

reappearance of a previously reinforced behavior when the replacement behavior contacts extinction

something that alters the value of a reinforcer and the current frequency of related behavior

stimulus control restricted to a very limited set of features

future behavior decreases because a stimulus is removed

reinforcement after a fixed number of responses

disruption in responding following an abrupt increase in ratio requirements

behavior occurs as the result of lawful causes

the overall process of identifying variables maintaining problem behavior to guide treatment

an MO that depends on learning history

brief verbal statements delivered contingent on behavior to reduce future behavior
