Motivating operations Flashcards
Motivating operations
Change how much an organism wants something. A degree of deprivation increases the value of a reinforcer.
2 types of effects
Value altering and behaviour altering
An increase in the reinforcing effectiveness of some stimulus, object or event.
Establishing operation (EO)
A decrease in the reinforcing effectiveness of some stimulus, object or event.
Abolishing operation (AO)
An increase in the current frequency of behaviour that has been reinforced by some stimulus, object or event.
Evocative effect
A decrease in the current frequency of behaviour that has been reinforced by some stimulus, object or event.
Abative effect
Sd vs MO
Sd = reinforcement available MO = reinforcement valuable
Food as an example of an EO and AO.
Food deprivation (EO) increases the reinforcing effectiveness of food, and increases the current frequency of behaviours reinforced with food. Food ingestion (AO) decreases the reinforcing effectiveness of food, and decreases the current frequency of behaviours reinforced with food.
Unconditioned MOs (UMO)
Value-altering motivating effects that are unlearned
Man has just run a marathon
EO- sleep
AO- activity
Man outside in snow
EO- heat
AO- cold
Conditioned MOs (CMO)
Motivating variables that alter the reinforcing effectiveness of other stimuli, objects or events, but only as a result of an organism’s learning history.
3 types of CMO
CMO-S (surrogate)
CMO-R (reflexive)
CMO-T (transitive)
A previously neutral stimulus that, following temporal association with a UMO independently alters the probability of associated behaviours.
eg. hunger (UMO) paired with 12:00 (neutral). 12:00 becomes CMO-S and makes person feel hungry without presence of UMO.
CMO-S
A previously neutral stimulus that acquires its motivative effect through correlation with a set of worsening or improvement conditions.
Its onset establishes the value of its removal or continued presence.
eg. pain
CMO-R
