Question | Answer |
---|---|
anticipatory contrast | The process whereby the rate of response varies inversely with an upcoming ("anticipated") change in the rate of reinforcement. |
behavioral contrast | A change in the rate of _reinforcement_ on one component of a multiple schedule produces an opposite change in the rate of _response_ on another component. |
delayed matching-to-sample | An experimental procedure in which the animal is first shown a sample stimulus and then, following some delay, is required to select that stimulus out of a group of alternative stimuli. |
differential reinforcement of incompatible behavior (DRI) | The behavior being reinforced is incompatible with the behavior being extinguished. |
differential reinforcement of other behavior (DRO) | Reinforcement of any behavior other than a target behavior that is being extinguished. |
discrimination training | As applied to operant conditioning, the differential reinforcement of responding in the presence of one stimulus (the SD) and not another. |
discriminative stimulus for extinction (S∆) | A stimulus that signals the absence of reinforcement. |
errorless discrimination training | A discrimination training procedure that minimizes the number of errors (i.e., nonreinforced responses to the S∆) and reduces many of the adverse effects associated with discrimination training. |
extinction | The nonreinforcement of a previously reinforced response, the result of which is a decrease in the strength of that response. |
extinction burst | A temporary increase in the frequency and intensity of responding when extinction is first implemented. |
extinction burst, increase in variability, emotional behavior, aggression, resurgence, depression | Side effects of extinction. (6) |
fading | The process of gradually altering the intensity of a stimulus. |
functional communication training | Training to communicate one's desires clearly and appropriately. |
generalization gradient | A graphic description of the strength of responding in the presence of stimuli that are similar to the SD and vary along a continuum. |
multiple schedule | A complex schedule consisting of two or more independent schedules presented in sequence, each resulting in reinforcement and each having a distinctive SD. |
negative behavioral contrast | The process whereby an increase in the rate of reinforcement on one component of a multiple schedule produces a decrease in the rate of response on the other component. |
partial reinforcement effect | The process whereby behavior that has been maintained on an intermittent (partial) schedule of reinforcement extinguishes more slowly than behavior that has been maintained on a continuous schedule. |
peak shift effect | Following discrimination training, the peak of a generalization gradient will shift from the SD to a stimulus that is further removed from the S∆. |
positive behavioral contrast | The process whereby a decrease in rate of reinforcement on one component of a multiple schedule produces an increase in the rate of response on the other component. |
regression | The reappearance of immature behavior in reaction to frustration or conflict. |
resistance to extinction | The extent to which responding persists after an extinction procedure has been implemented. |
resurgence | The reappearance during extinction of other behaviors that had once been effective in obtaining reinforcement. |
schedule of reinforcement (partial, VR), history, magnitude, degree of deprivation, previous experience with extinction, distinctive signal for extinction | Factors affecting resistance to extinction. (6) |
spontaneous recovery | The reappearance of an extinguished response following a rest period after extinction. |
stimulus control | A situation in which the presence of a discriminative stimulus reliably affects the probability of a behavior. |
stimulus discrimination | In operant conditioning, the tendency for an operant response to be emitted more in the presence of one stimulus than another. |
stimulus generalization | In operant conditioning, the tendency for an operant response to be emitted in the presence of a stimulus that is similar to an SD. |
