Term
| Absolute stimulus control |
|
Definition
| When operants are regulated by the physical properties of a stimulus |
|
|
Term
|
Definition
| A change in the rate of response during one component of a multiple schedule of reinforcment that is caused by a change in an anticipated upcoming component |
|
|
Term
|
Definition
| When a change in one component of a multiple schedule affects the rate of response in an unchanged component of that schedule |
|
|
Term
| Conditional discrimination |
|
Definition
| A discrimination in which reinforcement of responding in the presence of one stimulus depends on another stimulus |
|
|
Term
|
Definition
| A stimulus or event that alters the probability of an operant when presented |
|
|
Term
| Delayed matching to sample (DMTS) |
|
Definition
| A matching to sample procedure in which there is a delay between the presentation of the sample stimulus and the presentation of the SD |
|
|
Term
| Differential reinforcement |
|
Definition
| Reinforcing responses with certain characteristics and not reinforcing responses without those characteristics |
|
|
Term
| Differential reinforcement of other behavior (DRO) |
|
Definition
| A schedule where reinforcers are provided for any response that is not some specified target behavior |
|
|
Term
|
Definition
| When an individual responds differently in different situations |
|
|
Term
| Discrimination index (ID) |
|
Definition
| A measure of stimulus control that represents a ratio of the rate of behavior in the presence of and SD to the sum of the rates of behavior in the presence of the SD and in the presence of the SΔ |
|
|
Term
| Discriminative stimulus (SD) |
|
Definition
| A stimulus or event that signals a response-reinforcer relationship and thus sets the occasion for that response to occur |
|
|
Term
| Errorless discrimination (a.k.a. errorless learning) |
|
Definition
| A discrimination training procedure that starts with an established discrimination between an SD and SΔ and gradually changes the SΔ over the course of training until the the individual has learned to discriminate the SD from a new SΔ without ever (or rarely) having made the mistake of responding to the SΔ. |
|
|
Term
|
Definition
| Transferring stimulus control from one stimulus to another by gradually changing the characteristics of the controlling stimulus |
|
|
Term
|
Definition
| The spread of control from a particular stimulus or situation to other stimuli or situations that differ from the original along one or more dimensions |
|
|
Term
|
Definition
| A graph that shows the relation between probability of response and stimulus values that differ along some dimension from an SD (or CS in respondent conditioning) |
|
|
Term
|
Definition
| A conditional discrimination in which the determination of which of several stimuli, called comparison stimuli, is the SD depends on another stimulus, called the sample, to which it is matched |
|
|
Term
|
Definition
| Two or more simple schedules are presented one after the other and a unique discriminative stimulus is associated with each |
|
|
Term
|
Definition
| When a change in one component of a multiple schedule leads to a decrease in the rate of response in an unchanged component of that schedule |
|
|
Term
|
Definition
| A displacement in the peak of a generalization gradient to one side of the SD in a direction away from the SΔ |
|
|
Term
|
Definition
| When a change in one component of a multiple schedule leads to an increase in the rate of response in an unchanged component of that schedule |
|
|
Term
| Relative stimulus control |
|
Definition
| When operants are regulated by the relationship between properties of two or more stimuli |
|
|
Term
|
Definition
| A response occasioned by a controlling stimulus that is not present at the time of the response |
|
|
Term
|
Definition
| A sequence of responses in which each response produces a the SD for the next response in the sequence until the terminal response of the sequence is performed |
|
|
Term
|
Definition
| The time between offset of the sample stimulus and onset of the comparison stimuli |
|
|
Term
| S-delta (SΔ; a.k.a. extinction stimulus) |
|
Definition
| A stimulus or event that signals the absence of a response-reinforcer relationship and thus sets the occasion for that response to not occur or occur a reduced rate |
|
|
Term
| Simultaneous discrimination |
|
Definition
| A procedure where the SD and SΔ(s) are presented at the same time |
|
|
Term
|
Definition
| The discriminative control of behavior by controlling stimuli |
|
|
Term
|
Definition
| When a behavior conditioned with a specific stimulus also occurs in the presence of other stimuli that differ from the original stimulus along one or more dimensions |
|
|
Term
| Successive discrimination |
|
Definition
| A training procedure where only one controlling stimulus is present at a time |
|
|
Term
|
Definition
| Behavior that is acquired or maintained by accidental relations between the behavior and reinforcement |
|
