stim·u·lus gen·er·al·i·za·tion

in pavlovian conditioning, the eliciting of a conditioned response by stimuli never before experienced but similar to a particular conditioned stimulus. See: conditioning, classical conditioning.

stimulus generalization

a type of conditioning in which the reaction to one stimulus is reinforced to allow transfer of the reaction to other occurrences.

stim·u·lus gen·er·al·i·zation

(stimyū-lŭs jenĕr-ăl-ī-zāshŭn)
In pavlovian conditioning, eliciting a conditioned response by stimuli never before experienced but similar to a particular conditioned stimulus.

stimulus

pl. stimuli [L.] any agent, act, or influence that produces functional or trophic reaction in a receptor or an irritable tissue.

conditioned stimulus
a neutral object or event that is psychologically related to a naturally stimulating object or event and which causes a conditioned response. See also conditioning.
discriminative stimulus
a stimulus associated with reinforcement, which exerts control over a particular form of behavior; the subject discriminates between closely related stimuli and responds positively only in the presence of that stimulus.
eliciting stimulus
any stimulus, conditioned or unconditioned, which elicits a response.
stimulus generalization
in learning by animals stimuli tend to be grouped together, the reactions lacking the discrimination of the higher mammals.
stimulus response coupling
coupling of the neural or endocrine stimulus to the cellular response.
structured stimulus
a well-organized and unambiguous stimulus, the perception of which is influenced to a greater extent by the characteristics of the stimulus than by those of the perceiver.
threshold stimulus
a stimulus that is just strong enough to elicit a response.
unconditioned stimulus
any stimulus that is capable of eliciting an unconditioned response. See also conditioning.
unstructured stimulus
an unclear or ambiguous stimulus, the perception of which is influenced to a greater extent by the characteristics of the perceiver than by those of the stimulus.

A model for adaptation-level effects on stimulus generalization.
Perhaps it would be expeditious to not "beat around the bush" and simply recognize that these two sets of stimuli involved using and understanding this idiom have less in common, which behaviorally makes them less likely to evoke or support the stimulus generalization necessary to understand them.
A further study of stimulus generalization following three-stimulus discrimination training.
The first difference is that Durand (1999) and Durand and Carr (1991) used a multiple exemplars (Stokes & Baer, 1977) approach to training, which can be an effective procedure for promoting stimulus generalization.
The stimulus generalization program was identical to the perspective-taking program (57 total trials) except the relation questions included different stimuli (e.
Decisions regarding behavioral interventions, such as shaping or stimulus generalization, often rely on data from behavior assessment such as interviews and observations from both clinical and naturalistic settings.
The results of the control animals showed die expected stimulus generalization gradient around S+.
For example, whereas researchers have traditionally studied stimulus generalization and gradient shift using unidimensional stimuli (Honig and Urcuioli 1981; Purtle 1973; Riley 1968), a number of researchers have more recently studied gradient shift using naturalistic images of human faces (e.
An experimental analysis is carried out to establish the variables that will bring about stimulus control and stimulus generalization.
A future challenge for our behavioral engineering will be to develop procedures to refine the discrimination skills of our monkeys such that stimulus generalization is a less likely outcome.
While response generalization is certainly welcomed, the applied behavior analyst is often most concerned with stimulus generalization.
Perhaps, therefore, unspecified or uncontrolled primary stimulus generalization effects among the stimuli could be used to explain the findings of the current study (see Hoon et al.
