EAP Mod 3 Vocabulary
Experimental Analysis of Behavior Module 3 Vocabulary and Definitions
| Term | Definition |
|---|---|
| Absolute Threshold | when measuring the perception of a particular stimulus this is the minimum intensity that can be detected by the stimulus |
| Difference Threshold | when measuring the perception of a particular stimulus this is the least noticeable change in the intensity of the stimulus |
| Scaling Laws | laws that describe the observable and consistent relation between perception and actual stimulus intensity, help guide measurement of discrimination and generalization |
| Stimulus Discrimination | ability to identify and respond appropriately to a specific/particular stimulus or environmental event in the presence of another different stimuli/environmental event |
| Discriminative Stimulus (SD) | in the presence of a stimulus a given response is likely to be reinforced if it occurs, antecedent signals the behavior will likely receive reinforcement if it occurs |
| (S-delta) | stimulus that signals a response is not likely to produce reinforcement |
| Errorless Discrimination (not learning/teaching) | the subject/learner's ability to withhold responding/no response to the presence of a stimulus paired with extinction without error |
| Stimulus Control Transfer | the systematic shift of the preexisting discriminative stimulus that has control over a behavior to another new stimulus wherein the new stimulus is able to express control over that same behavior (various procedures used)*Highlights stimulus relationship |
| Conditional Discrimination | subjects correct response/ding to a sample SD is dependent on the presence of another comparison stimulus (*often studied with matching-to-sample procedures) |
| Matching-to-Sample (not procedures) | subjects correct response of choosing a previously introduced sample stimulus amongst two or more comparison stimuli (*depends solely on which sample is presented) |
| Oddity Matching | |
| Stimulus Generalization | when a behavior response that was reinforced under previous stimulus (SD)/event also occurs in response to similar stimuli/events due to the learner expanding their repertoire and ability to discriminate amongst varying but similar stimuli |
| Generalization Gradient | graph that shows subjects response rate to different stimuli along continuum, reveals progress of generalization, power of stimulus control and SD training effect on responding, steep= (strong control/<generalization and flat=weak control/>generalization |
| Peak Shift | a generalization gradient shift during SD training between two stimuli where maximum responding may not occur with the reinforced stimuli but to a stimulus that's slightly further from the non-reinforced cue (*peak shift effect in SD generalization) |
| Stimulus Equivalence | emergence of relationships between varying stimuli that were not directly trained during conditional discrimination procedures, including reflexivity, transitivity, and symmetry learning properties (*Sidman, 1971) |
| Reflexivity (stimulus equivalence) | stimulus matched to itself as in A-A, subject is able to match the same comparison sample stimulus to the same sample presented |
| Symmetry (stimulus equivalence) | matching of stimulus in reverse, subject is able to match A to B then B to A without further conditioning |
| Transitivity (stimulus equivalence) | matching two stimulus that are related then forming a new relation between them and a new stimulus that was never conditioned, subject learns that if A-B and B-C then A matches C |
| Instructional Control | instructor's ability to place subject under conditions wherein consistent responding to their teachings from the subject is observed, developed by instructor being reliably associated with contingent reinforcement |
| Rule-Governed Behavior | behavior under the control of implied rules programmed into the individual's repertoire verbally, consequence does not have to occur for the behavior to persist rather the individual simply follows the rules and their Bx reflects the abidance |
