| Term | Definition |
|---|---|
| abative effect | A decrease in the current frequency of behavior that has been reinforced by some stimulus, object, or event whose reinforcing effectiveness depends on the same motivating operation. |
| abolishing operation (AO) | A motivating operation that decreases the reinforcing effectiveness of a stimulus, object, or event. For example, the reinforcing effectiveness of food is abolished as a result of food ingestion. |
| behavior-altering effect | Either (a) an increase or (b) a decrease in the current frequency of behavior that has been reinforced by some stimulus, object, or event, called an evocative effect |
| conditioned motivating operation (CMO) | A motivating operation whose value-altering effect depends on a learning history. |
| establishing operation (EO) | A motivating operation that increases the effectiveness of some stimulus, object, or event as a reinforcer. For example, food deprivation establishes food as an effective reinforcer. |
| evocative effect | An increase in the current frequency of behavior that has been reinforced by some stimulus, object, or event whose reinforcing effectiveness depends on the same motivating operation. |
| motivating operation (MO) | An environmental variable that (a) alters the reinforcing or punishing effectiveness of some stimulus, object, or event; and (b) alters the current frequency of all behavior that has been reinforced or punished by that stimulus, object, or event. |
| reflexive conditioned motivating operation (CMO-R) | A stimulus that acquires MO effectiveness by preceding some form of worsening or improvement. It is exemplified by the warning stimulus in a typical escape–avoidance procedure. |
| reinforcer-abolishing effect | A decrease in the reinforcing effectiveness of a stimulus, object, or event caused by a motivating operation. For example, food ingestion abolishes (decreases) the reinforcing effectiveness of food. |
| reinforcer-establishing effect | An increase in the reinforcing effectiveness of a stimulus, object, or event caused by a motivating operation. For example, food deprivation establishes (increases) the reinforcing effectiveness of food. |
| surrogate conditioned motivating operation (CMO-S) | A stimulus that acquires its MO effectiveness by being paired with another MO and has the same value-altering and behavior-altering effects as the MO with which it was paired. |
| transitive conditioned motivating operation (CMO-T) | An environmental variable that, as a result of a learning history, establishes (or abolishes) the reinforcing effectiveness of another stimulus and evokes (or abates) the behavior that has been reinforced by that other stimulus. |
| unconditioned motivating operation (UMO) | A motivating operation whose value-altering effect does not depend on a learning history. For example, food deprivation increases the reinforcing effectiveness of food without the necessity of any learning history. |
| value-altering effect | Either (a) an increase in the reinforcing effectiveness of some stimulus, object, or event, in which case the MO is an establishing operation (EO); or (b) a decrease in reinforcing effectiveness, in which case the MO is an abolishing operation (AO). |
