A Concept Learning Model, Charles R. Sawyer
A Concept Learning Model, Charles R. Sawyer
Psychology ETDs
An analysis of rule learning (RL) data suggests that an important factor in bidimensional concept learning is the degree to which stimuli share common stimulus values. Subjects have the most difficulty with differentially assigned stimuli which have common values and with stimuli which are assigned to the same response category but have no common values. Based on these findings, an experiment was run with four bidimensional stimuli to determine how Ss will respond to non-reinforced test stimuli after the reinforcement of one or two stimuli to the same or different response categories. The data indicated that Ss responded to a …
The Relative Usefulness Of Exemplars And Non-Exemplars For Solving Attribute Identification Concept Tasks, Thomas C. Toppino
The Relative Usefulness Of Exemplars And Non-Exemplars For Solving Attribute Identification Concept Tasks, Thomas C. Toppino
Psychology ETDs
The effects of category label (positiveness or negativeness) and category composition (differences in the stimuli composing each category) were investigated in two experiments with concepts which were previously deemed most likely to yield a persistent advantage to positive instances. Category label effects were separated from category composition effects by using pairs of complementary concepts and requiring Ss to solve with only positive instances or only negative instances. Results showed that category composition was a more important determiner of performance than was category label. The relatively weak category label effects which were obtained were limited to specific conditions of category composition. …
The Effects Of Group Systematic Desensitization On The Symptoms Of Primary Dysmenorrhea, Steven Kenneth Reich
The Effects Of Group Systematic Desensitization On The Symptoms Of Primary Dysmenorrhea, Steven Kenneth Reich
Individual, Family, and Community Education ETDs
The purpose of this study was to examine the effects of group systematic desensitization on the symptoms of primary dysmenorrhea in relation to anxiety. The sample consisted of an experimental group of 12 women drawn from the University of New Mexico Student Health Center and the Presbyterian Hospital School of Practical Nursing who were treated in four sessions with group systematic desensitization focused on menstruation, and a control group drawn from the Bernalillo County Planned Parenthood Association not treated with group systematic desensitization. The experimental subjects were treated in small groups, utilizing semi-automated procedures through the use of tape recordings, …
The Effects Of Perceptual Pretraining On Concept Identification And Preference, Rene S. Silleroy
The Effects Of Perceptual Pretraining On Concept Identification And Preference, Rene S. Silleroy
Psychology ETDs
The effects of perceptual pretraining on preferences and concept identification performance in five and eight year old Ss were investigated. Perceptual pretraining consisted of unreinforced same-different judgments on stimuli varying on each of the five task dimensions. The results indicated that perceptual pretraining facilitated performance on a concept identification task with a nonpreferred relevant cue for the five year olds but not for the eight year olds. However, perceptual pretraining did not affect preference in either age group and Ss were as consistent in their preference responding before and after perceptual pretraining as was a control group that had not …
An Operational Analysis Of The Value Of The Nonoutcome Trial In Children's Discrimination Learning, Thelma A. Giomi
An Operational Analysis Of The Value Of The Nonoutcome Trial In Children's Discrimination Learning, Thelma A. Giomi
Psychology ETDs
Numerous and divergent interpretations of the value of the blank or nonoutcome trial (N) in combination with reinforcement or punishment have been suggested. In all these interpretations N is considered as a response inferred construct. The present study was conducted to directly test the value of N in differential feedback combinations and to provide a critical evaluation of these various interpretations. The experiment consisted of a two phase study employing two simultaneous discrimination problems. In the first discrimination 90 Ss learned a two choice simultaneous discrimination under one of three feedback conditions, reinforcement following a correct response and punishment following …
The Role Of Imagery In Association Formation And Stimulus Recognition, Boyd C. Tatum
The Role Of Imagery In Association Formation And Stimulus Recognition, Boyd C. Tatum
Psychology ETDs
Three experiments were performed in order to investigate the role that imagery plays in association formation and stimulus recognition. It was hypothesized that response terms of high imagery (I) value would produce enhanced recognition of the stimulus term over response terms of Low I value in a paired-associate (PA) task. Experiment I tested this hypothesis using High-I and Low-I response terms which bore a conceptual relationship to the stimulus terms. The stimuli were trigrams and the responses were nouns rated either High I or Low I. The Ss (undergraduate students) were trained under the study trial/test trial method and received …
