Term
|
Definition
| a decrease in the current frequency of behavior that has been reinforced by the stimulus, object, or event whose reinforcing effectiveness depends on the same motivating operation. |

|
Term
|
Definition
| a motivating operation that decreases the reinforcing effectiveness of a stimulus, object, or event |
|
|
Term
| behavior-altering effect (of a motivating operation) |
|
Definition
| Either (a) an increase in the current frequency of behavior that has been reinforced by some stimulus, object, or event, called an evocative effect; or (b) a decrease in the current frequency of behavior that has been reinforced by some stimulus, object, or event, called an abative effect. For example, the current frequency of behavior that has been reinforced with food, such as opening the fridge, is evoked (increased) or abated (decreased) by food deprivation or food ingestion, respectively. |

Definition
| the value-altering affect depends on a learning history |
|
|
Term
|
Definition
| an increase in the current frequency of behavior that has been reinforced by the stimulus that is increased in reinforcing effectiveness by the same motivating operation |
|
|
Term
|
Definition
| a change in the MO, stimulus, and response relations; caused by reinforcement, punishment, an extinction procedure, or a recovery from punishment procedure; results from the pairing and un-pairing of antecedent stimuli |
|
|
Term
| motivating operation (MO) |
|
Definition
| An environmental variable that (a) alters (increases or decreases) the reinforcing or punishing effectiveness of some stimulus, object, or event; and (b) alters (increases or decreases) the cur-rent frequency of all behavior that has been reinforced or punished by that stimulus, object, or event |
|
|
Term
| Reflexive Conditioned Motivating Operation (CMO-R) |
|
Definition
| a stimulus that acquires MO effectiveness by preceding some form of worsening or improvement; like a warning stimulus |
|
|
Term
| Surrogate Conditioned Motivating Operations (CMO-S) |
|
Definition
| 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 |
|
|
Term
| Transitive Conditioned Motivating Operation (CMO-T) |
|
Definition
| an environmental variable that, as a result of learning history, establishes (or abolishes) the reinforcing effectiveness of another stimulus and evokes (or abates) the behavior that has been reinforced by other stimulus |
|
|
Term
|
Definition
| A motivating operation that increases the effectiveness of some stimulus, object, or event as a reinforcer. For example, food deprivation established food as an effective reinforcer. |
|
|
Term
| Reinforcer-abolishing effect (of a motivating operation) |
|
Definition
| 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. |
|
|
Term
| reinforcer-establishing effect |
|
Definition
| 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. |
|
|
Term
| Unconditioned motivating operation (UMO) |
|
Definition
| 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. |

Definition
|
|
Term
| value-altering effect (of a motivating operation) |
|
Definition
| Either (a) an increase in the reinforcing effectiveness of some stimulus, object, or event, in which case the MO is an estavlishing operation (EO); or (b) a decrease in reinforcing effecttiveness, in which case the MO is an abolishing operation (AO). For example, the reinforcing effectiveness of food is altered as a result of food deprivation and food ingestion. |
