The Development Of A Personalized Computer Assisted School Psychology (Casp) System, Patricia Lou Steinert

Dissertations

The purpose of this project was to develop a model computer system to assist school psychologists in managing and manipulating data accumulated in the course of accomplishing their professional responsibilities. School psychologists have traditionally generated large amounts of data, but rarely have they looked across these data to obtain information and/or feedback about their own functioning relative to their professional role. The system described is intended as a model from which an individual psychologist might construct a system to meet individual needs. Data across students were accumulated in four broad areas: (1) personal effectiveness/accountability, (2) diagnosis, (3) local test norms, …

Self-Control In Mentally Retarded Adolescents: Choice As A Function Of Amount And Delay Of Reinforcement, Steven P. Ragotzy

Dissertations

Three severely mentally retarded adolescents were studied under discrete-trial procedures in which a choice was arranged between edible reinforcers that differed in magnitude and, in some conditions, delay. In the absence of delays, the larger reinforcer was consistently chosen. All subjects directed the majority of choice responses to the smaller reinforcer when the larger reinforcer was sufficiently delayed, although the value at which this occurred differed across subjects. Under conditions where the larger reinforcer initially was sufficiently delayed to result in preference for the smaller one, progressively increasing in 5-s increments the delay to both reinforcers increased percent trials with …

Effects Of Response Requirements And Reinforcement Probability On The Latency To Depress A Foot Treadle, Terri Deborah Starin

Masters Theses

Previous studies have shown response latency to be a sensitive measure of die effects of many experimental manipulations. However, when key pecking is the required response topography, it is difficult to ascertain whether latency is exclusively due to the effects of the independent variable or is confounded by respondent influences. The present study attempts to separate operant from respondent influences on response latency by requiring a response topography that is unlikely to have respondent components. Three pigeons responded under a multiple fixed-rado fixed-ratio schedule of food delivery with a 5 s intertrial interval separating trials. For two subjects, the independent …

The Effects Of Spouse-Based Cognitive-Behavior Therapy On The Treatment Of Agoraphobia, Joan Woods

Dissertations

The purpose of this clinical research was to determine whether spouse-supported treatment of agoraphobia would result in greater improvement on measures of exposure and avoidance than would individual treatment or no treatment. It was hypothesized that Couples Treatment subjects would demonstrate a significantly greater change from pretest to posttest than would Individual Treatment subjects or No-Treatment Control subjects. The study further predicted that significant improvements would be demonstrated for both treated groups on the same outcome measures, pretest to posttest and from pretest to follow-up.

Total N was 10 subjects, all were agoraphobic, married, and female, with 4 in Couples …

Effects Of Terminal-Link Response Topography On Choice Behavior Under Concurrent-Chains Schedules, Stephen P. Starin

Dissertations

Previous research has indicated that both absolute response rate and choice behavior differs under concurrent chains requiring different terminal-link responses, even when the reinforcement schedules are nominally identical. To date, no studies have investigated responding under concurrent chains with unequal schedules and different topographies arranged in the terminal links. Moreover, although the delay-reduction hypothesis has been widely tested using concurrent chains in which the same response topography is required in all links, the generality of the delay-reduction hypothesis in describing performance when different terminal-link topographies are required has yet to be examined. The present study was designed to address both …

Self-Control: Effects Of Ratio Size, Intra-Delay Reinforcers, And Response Requirement, Elbert Q. Blakely Jr.

Dissertations

This study tested the following hypotheses: (a) The preference reversal phenomenon will be found when the delays to reinforcement are defined by fixed-ratio schedules, (b) The preference reversal phenomenon will be observed when intra-delay reinforcers are programmed, and (c) Imposing response requirements during the delay to reinforcement will affect preference for a larger delayed reinforcer over a smaller more immediate reinforcer. In Experiment 1, pigeons chose between two schedules, each a sequence of two fixed-ratio schedules. The second schedule of one sequence offered a small reinforcer and the second schedule of the alternative offered a larger reinforcer. The latter sequence …
