A Comparison Of Reading And Listening Performances Of Braille And Print Readers, Betty P. Zook

Masters Theses

Blind and sighted subjects were tested on their capability to retain information after both reading and listening to specially prepared printed and taped materials. The sample consisted of graduate students and professional individuals. It was found that, on the average, subjects retained more after reading than listening. This effect was more pronounced in the braille reading subjects. As the level of complexity of the material increased, the difference in the points earned between the two modalities, reading and listening, increased significantly. A behavioral analysis suggested some reasons for this difference. It was suggested that further research into reading and listening …

Matching-To-Sample In The Pigeon: An Analysis Of The Effects Of Correction And Noncorrection Procedures, Deborah Lou Grossett

Masters Theses

Contradictory results concerning the effect that presence or absence of a correction procedure has on matching-to-sample were obtained by past studies (Carter and Werner, 1978; Thomas, 1979). Carter and Werner (1978) reported that exposure to a correction procedure resulted in an increase in accuracy, while Thomas (1979) found no difference between the noncorrection and correction procedures. The present study showed that exposure to a correction procedure resulted in an increase in accuracy in comparison to a noncorrection procedure during acquisition, but not during maintenance.

Past studies (Holt and Shafer, 1973; Thomas, 1979), using a correction procedure, showed that presence of …

The Perceived Utility Of The Job Model As A Planning Document For Faculty Members, Victoria Kai-Cacho

Masters Theses

A job model for faculty activity plans was developed based on an interview and a questionnaire response from 14 Western Michigan University professors. Perceived accuracy and usefulness of the job model were measured by a questionnaire designed by the investigator. Responses were analyzed by computing the mean ratings of each item included in the questionnaire. The job model was perceived as an accurate and useful instrument for faculty activity plans, self-development and faculty evaluation. However, methodological limitations suggest that further empirical research with a large sample and participation of administrative officers and students, in addition to faculty members, will be …

Choice As A Dependent Measure In Autoshaping: Sensitivity To Frequency And Duration Of Food Presentation, Mitchell Jon Picker

Masters Theses

Previous investigations have shown that rate, latency, and percentage of trials with at least one response are somewhat insensitive measures of the strength of autoshaped responding. In two experiments, nine pigeons were exposed to an autoshaping procedure in which the successive presentation of three stimuli were followed by food on either 100%, 50%, or 0% of the trials. Choice testing involved the simultaneous presentation of the three stimuli. In Experiment I, all pigeons consistently directed their initial choice responses and the majority of subsequent responses to the stimulus always followed by food. In Experiment II, rate, latency, and percentage of …

Response Latency: A Function Of Within-Session Differences In Intertrial Interval, Training History, Cue Condition, And Ratio Requirement, James Bryant Nuzzo

Masters Theses

Skinner has suggested that latency does not vary in an orderly manner and short latencies result from the development of effective waiting behavior not specified by the experimental contingencies. Recent experimentation has found latency to vary as a function of a within-session difference in parameters of reinforcement correlated with two components of a discrete-trial multiple schedule. Also found was the attenuation of within-session differences in latencies with the change in intertrial interval (ITI) from 5 seconds to 20 seconds. This suggests that the ITI may be variable which controls latency. This study investigated the effect on latency of within-session differences …

The Effects Of Total Darkness On Stimulus Control, Richard E. Schulman

Masters Theses

This experiment examined auditory stimulus control in a totally darkened as opposed to an illuminated chamber. All subjects (pigeons) were trained to keypeck in the presence of only a dimly lit green keylight, which was faded until responding was reliably occurring in a totally darkened chamber. When behavior stabilized under a Variable Interval (VI) 30 second schedule of reinforcement in a darkened chamber, subjects were divided into two groups for discriminating training. A Multiple VI 30 second Extinction (EXT) schedule was in effect, with 1-minute components separated by 5-second time-outs. The discriminative stimulus correlated with the VI component was a …
