In the field of stimulus generalization, an old yet unresolved discussion pertains to what extent stimulus misidentifications contribute to the pattern of conditioned responding. In this article, we perform cluster analysis on six datasets (four published datasets and two unpublished datasets, included N = 950) to examine the relationship between…

We investigated the role of cholinergic neurotransmission in olfactory fear learning. Mice receiving pairings of odor and foot shock displayed fear to the trained odor the following day. Pretraining injections of the nicotinic antagonist mecamylamine had no effect on subsequent freezing, while the muscarinic antagonist scopolamine significantly…

Investigated simultaneous occurrence of emergent stimulus-response relations (functional equivalence) and stimulus-stimulus relations (stimulus equivalence). Trained 4- and 5-year olds to emit specified responses to pairs of stimuli in one setting (original training) and to emit other responses to one member of each pair in another setting…

Purpose of the present research was to determine whether certain Pavlovian conditioning phenomena occur in a simple probability learning situation. (Authors)

Children and adults were trained and tested on formation of novel simple discriminations and conditional stimulus relations. Subjects who formed these sets were trained and tested on formation of stimulus equivalence classes. A modest majority of children matched directly paired stimuli; a few matched indirectly paired stimuli. All normal adults…

In this study, a transfer of stimulus control procedure was used to establish generalized verb-noun instruction-following skills in two severely retarded boys. (Author/JH)

Study supported by grant HD-00879 from the National Institute of Child Health and Human Development, and presented in part at the Society for Research and Child Development meeting, 1966.

Four male and five female Negro children (ranging in age from 5 to 9 years) served in an experimental comparison of the discriminative control exerted by sex and race aspects of other children. A baseline was established in which color photoslides of a Negro girl and a Caucasian boy differentially controlled responding on two push buttons.…

Major purpose of the experiments was to use an instrumental response to study the form of semantic generalization gradients obtained following single-cue and discrimination training procedures. (Authors)

Two children (ages 10 and 12) with severe mental retardation were trained to make the same response when presented with 2 initially unrelated stimuli and then trained to make a new response when presented with 1 of those stimuli. Children were then assessed on their response to the second stimulus. Results of the tests for the emergent…

In earlier studies with rats, the effectiveness of the auditory element of a tone--light discriminative stimulus was enhanced when the conditioned incentive value of the compound was negative rather than positive. The present experiment systematically replicated these results in pigeons trained to press a treadle in the presence of a tone--light…

This paper develops a stimulus selection theory, based on an extensive review of previous research, which gives weight to context change or stimulus generalization decrement. The theory assumes no special compounding or configurational process, and accounts for the learning of successive discriminations without the addition of any special process.…

Investigated whether women undergoing outpatient chemotherapy for breast cancer can develop classically conditioned emotional distress. Patients' responses to a distinctive stimulus were assessed in a location not associated with chemotherapy administration. Results supported hypothesis that pairing a distinctive stimulus with chemotherapy would…
