The Effects Of Mechanically-Delivered Human-Delivered Reinforcement And Human-Delivered Reinforcement On Intrinsic Interest, Duangkaew Ungsrithong

Masters Theses

The objective of this study was to compare the effects of mechanically-delivered and human-delivered reinforcement on the performance of intrinsically interesting tasks. The study used a multiple-trial within-subject comparison design in which two reinforcement phases (a human-delivered reinforcement and a mechanically-delivered reinforcement phase) were alternated with two post-reinforcement phases. Three of the four subjects did not show performance decrements following mechanically-delivered reinforcement while three did show decrements following human-delivered reinforcement. These data indicate that post-reinforcement decrements may be more likely when reinforcement is delivered socially, suggesting that such decrements may not be due to the reinforcers per se but to …

A Comparison Of Retail Sales Performance Under Individual And Group Quota Systems, Karen Beth Bishop

Masters Theses

The research goal of this study was to determine if changing from an individual to a group quota system changed variability in sales performance. Data were collected within three branches of the company. Within subject and within group variances were calculated using salesclerk's sales figures. Three months of 1986 represented individual quota figures, while the same three months of 1987 represented group quota figures. Results of the within group variance found two departments had a variance decrease and one department had a variance increase. Cumulative sales for both systems found decreases in sales using the group quota system for two …

Possible Role Of Petroliferous Materials In Sulfide Precipitation At The Frank R. Millikan Mine, Southeast Missouri, Clark Alan Niewendorp

Masters Theses

The Millikan Mine's ore body contains ubiquitous amounts of petroliferous materials occurring as blebs, coal-like pods and veinlets, and seeps coating mine stope walls. Emplacement of hydrocarbons into the ore occurred before the final episode of mineralization ceased, based on growth of dendritic galena in some coal-like bitumen and other paragenetic relationships. Growth of dendritic galena in a hydrocarbon substance suggests that hydrocarbons provided sulfur for galena mineralization by either abiogenetic reduction of sulfate or thermochemical evolution of organic sulfur. Texturally, it also suggests that the presence of hydrocarbons may have been responsible for some zones of rapid precipitate mineralization. …

The Evolution Of Text Formatting Languages, Dirk Herr-Hoyman

Masters Theses

Text, as seen in books and magazines, can take on three forms: string, graphic (two-dimensional), and image (digitized pictures). Text formatting processes text into a representation suitable for printing. Since a printer is really a computer, this representation is machine code for the printer. ASCII is one such code.

Six historically significant text formatting languages are surveyed: Runoff, Troff, TeX, Bravo, Scribe, and Postscript. The emphasis is on the text types available and the code generated. The main evolutionary forces are the changes in printers. Comparisons are made with programming languages.

Each of the six languages has ASCII as its …

The Effects Of Oil Well Sites On Forest Species Of Birds, Wendy J. Baker

Masters Theses

Fifty censuses were taken in 9 transects adjacent to 8 oil well openings. It was found that 2 species, the red-eyed vireo (Vireo olivaceus), and the ovenbird (Seiurus aurocapilus) were significantly affected in spatial distribution. These forest species had significantly lower numbers near the oil well site than in the forest. Two other forest species suggested the same pattern. The effect of the oil well site reaches well into the forest.

Other possible effects of the oil well sites are competition with edge species and brood parasitism by the brown-headed cowbird. Noisier sites may also affect the bird community within …

Effects Of Assertiveness Training And Cue Controlled Relaxation Training On Cardiovascular Reactivity To Social Stressors, Bernardine M. Pinto

Masters Theses

The objective of this study was to examine the effects of two interventions (assertiveness training and cue controlled relaxation training) on cardiovascular reactivity to role play simulations of social stressors. For this purpose, a single subject multiple-baseline experimental design was employed. Four subjects (three female and one male) received assertiveness training (which focused on behavioral components of assertiveness) and cue controlled relaxation training. Following assertiveness training, subjects responded assertively to the role plays but their blood pressure reactivity was not reduced. Cue controlled relaxation appeared to reduce blood pressure reactivity to a limited extent. Factors associated with the effects of …

The Effects Of Magnitude Of Extrinsic Reinforcement On Intrinsic Interest: An Experimental Analysis, Brian Howard Gribler

Masters Theses

The present study examined the effect that three magnitudes of extrinsic reinforcement had on wheel running following the termination of reinforcement. After an initial baseline period, three groups of rats were assigned to one of three conditions: a variable interval 60 second schedule of reinforcement, a variable time 60 second schedule of reinforcement, or a control condition. Each subject in the reinforcement groups was exposed to three different magnitudes of reinforcement. Each reinforcement phase was followed by a return to baseline. The results indicated that contingent reinforcement increased wheel running although rates were comparable for all magnitudes of reinforcement. No …

The Effects Of Music Videos On Adolescent Females Self-Concept And Body-Image, David Scott Eggli

Masters Theses

Music videos are a phenomenon of the 1980s. Their striking imagery, flashy choreography, sexy clothing, and quick cuts have attracted a huge audience of adolescents and changed the face of the fashion industry. If rock stars and music videos can attract millions of teenage viewers and change the style of clothes worn, they may also affect a teenager's self-concept and body-image.

The subjects in this research project were 18 adolescent females between the ages of 12 and 17. The subjects viewed either music videos or G-rated movies. The Piers Harris Children's Self-Concept Scale served as the dependent variable for pretest …

The Effects Of Activity Group Structure On Cohesion, Engagement, And Affective Meanings In Acute-Care Psychiatric Patients, Hope L. Brucki

Masters Theses

Through activity analysis, occupational therapists identify various components of group structure and group processes for use in therapeutic activities.

The Effect Of Assertiveness Training On Assertive Behavior And Corresponding Self-Descriptive Statements, James Scott Boland

Masters Theses

This study examines the changes in subjects' assertive behavior and corresponding changes in self-perceptions/-cognitions after assertiveness training. Based on the findings from cognitive dissonance studies, it is suggested that nonassertive subjects would begin to evidence assertive self-perceptions/cognitions if they learned to behave assertively via behavioral skill training methods. Three males and five females volunteered to undergo one session of baseline measures and four training sessions. Pre-treatment RAS, EIBS, and Baseline measures of behavior and cognitions as measured by changes in behavioral ratings and post-trial form responses. Post-training RAS and EIBS responses were similar to those found in assertive subjects. Results …

A Study-Support Program For High-Risk, Black College Freshman Enrolled In A General Psychology Course, Angela Michelle Williams

Masters Theses

As a replication of Jackson's (1984) work, this research compared the performance of three groups of college freshmen. The groups consisted of black, high-risk students who voluntarily enrolled in a study-support group because of their initial quiz scores. The support program required the students to study each week's psychology objectives in four smaller segments, rather than studying all the week's material at once. The assumption was that this would increase the students' contact with the study material and improve their performances. An ABA design was used. The participants in the support program received higher quiz scores and final grades than …

Responding Under Homogeneous Versus Heterogeneous Chained Variable-Interval Schedules, Stephen P. Starin

Masters Theses

Four pigeons responded under chained variable-interval schedules in which the required response topographies were either similar [i.e., a homogeneous chain] or dissimilar Ci.e., a heterogeneous chain]. Subjects were exposed to all possible combinations of initial-link key pecking or treadle pressing and terminal-link pecking or treadling. Three of four subjects displayed higher initial-link response rates under the homogeneous chains. The present results were explained in terms of an induction effect in which the strengthening effect of reinforcing a particular terminal-link response topagrapahy generalizes to similar responses earlier in the chain, but not to topographically different responses.

An Otopathological Assessment Of Dogs Exposed To Excessive Dietary Fluoride And/Or Suspected Water Borne Toxins, Barbara Ann Hannah

Masters Theses

In 1970, a once very productive Allegan, Michigan dog kennel began experiencing a rash o£ unexplained perinatal deaths and reproductive anomalies in Shetland pups. Anomalies including cleft palate and lip, kinked tails, twisted feet and convulsions immediately before death plagued the neonates. The adult dogs were reported to have tooth mottling, exostoses and auditory and vestibular problems.

Because the dogs had been on high fluoride diets and because the kennel well water was suspected of harboring toxins, a group of 20 Shetland dogs was used to try to find if there was any correlation between the reproductive problems and the …
