Determination Of Chromatic And Luminance Channels In The Zebrafish Visual System Using An Increment Threshold Technique, Richard Hughes Dec 1996

Determination Of Chromatic And Luminance Channels In The Zebrafish Visual System Using An Increment Threshold Technique, Richard Hughes

Masters Theses & Specialist Projects

It is well established that the primate visual system possesses anatomically separate chromatic and luminance channels; these pathways are responsible for the visual coding of color and brightness information, respectively. In lower vertebrates, such as the zebrafish (Danio rerio), there does not appear to be any anatomical separation of cell types mediating color and luminance information. However, several studies suggest that these vertebrates may be able to discriminate these attributes of a visual stimulus. The purpose of this study was to determine whether the zebrafish visual system possesses chromatic and luminance channels. In addition, the contribution of each cone photoreceptor …

In the study, I assessed the persistence of students who joined fraternities at Western Kentucky University. Also included is a comparison between them and the general student population. The study includes 1467 students who joined fraternities between the Fall 1986 to Spring 1991 semesters. A five-year time period was used as the benchmark for graduation from the institution. Factors that were explored included race, initiation status, year in school when pledging, and organizational affiliation. Pearson Product-Moment Correlations and Analysis of Variance (ANOVA) were used to analyze the data. The results illustrated that students who join fraternities graduate at a higher …


Linking Assessment To Intervention: Teacher Awareness And Training Needs Related To Students With Attention-Deficit Hyperactivity Disorder, Matthew Luckett Dec 1996

Linking Assessment To Intervention: Teacher Awareness And Training Needs Related To Students With Attention-Deficit Hyperactivity Disorder, Matthew Luckett

Masters Theses & Specialist Projects

Despite the efforts of private and federally funded research, which have led to a prodigious accumulation of information concerning the assessment and diagnosis of Attention-Deficit Hyperactivity Disorder and interventions for students diagnosed with ADHD, a minimal amount of research focus has centered around the application of assessment information in the development of treatment plans. The evolution of diagnostic labels for ADHD and variability among school-based assessment practices have impeded the utilization of assessment data in intervention planning. Although reaction to the challenges presented by ADHD students has been widespread, research generated by the interest in this heterogeneous population has only …


Work Redesign And Its Influence On Employee Motivation And Job Satisfaction, John Koscielniak Dec 1996

Work Redesign And Its Influence On Employee Motivation And Job Satisfaction, John Koscielniak

Masters Theses & Specialist Projects

Reengineering and work redesign have become the buzzwords of the healthcare industry giving rise to the unprecedented growth of reengineering / work redesign consultants who offer cookbook methods to make the organization efficient and reduce costs. The unfortunate consequence of this rush to redesign is that the employer accepts recommendations to change the organization without knowing the state of the workforce. The purpose of this research is to test the effects of work redesign as implemented at two for-profit hospitals using a measurement tool developed specifically for work redesign. The intent is to compare the hospitals separately as each work …


An Investigation Of Peripheral Localization Errors In Older Adults, Eric Stephens Dec 1996

An Investigation Of Peripheral Localization Errors In Older Adults, Eric Stephens

Masters Theses & Specialist Projects

In a typical useful field of view (UFOV) paradigm, an observer must correctly identify a center target while simultaneously localizing a peripheral target. Previous research has shown that many older adults have difficulty locating the peripheral target in the UFOV paradigm when compared to younger adults (Sekuler & Ball, 1986; Scialfa, Kline, & Lyman, 1987; Ball, Beard, Roenker, Miller, & Griggs, 1988; Ball, Roenker, & Bruni, 1990; Scialfa, Thomas, & Joffe, 1994). However, the reason for this difficulty is not clearly understood. The purpose of this study was to test two potential explanations for the difficulty that some older adults …


A Survey Of Black Student Perceptions And Attitudes On The Utilization Of Academic Retention Programs, Beora Willams Dec 1996

A Survey Of Black Student Perceptions And Attitudes On The Utilization Of Academic Retention Programs, Beora Willams

Masters Theses & Specialist Projects

In this study I examine the perceptions and attitudes of black students attending a predominantly white institution (PWI) concerning student support services designed to assist them in achieving social and academic success. PWIs have established minority retention programs with an overall mission of recruiting and retaining black students; however, program use is minimal and black students continue to depart college prematurely. This research seeks to assess the perceptions and attitudes of black students to determine if program ambiguity, lack of faculty involvement or available mentoring, campus affiliation, racism, or time taken away from academic pursuits has a role in whether …


The Effects Of Practice On Stroop Inhibition: A Process Dissociation Approach, Emily Patterson Dec 1996

The Effects Of Practice On Stroop Inhibition: A Process Dissociation Approach, Emily Patterson

Masters Theses & Specialist Projects

Two studies were performed to investigate the effects of age and practice on Stroop inhibition. The first experiment examined the influence of age on the ability to ignore the meaning of words on Stroop items. Fifteen younger and 15 older adults were asked to name the color of congruent, incongruent, and control items appearing on a computer screen. Participants' interference and facilitation scores, error rates, and color and word process dissociation estimates were computed. The results indicate that older adults experienced more interference and facilitation than the younger adults and produced more errors than the younger adults on items where …


Temporal Characteristics Of Zebrafish Cone Types And Their Role In Separate Visual Processing, Warren Patterson Dec 1996

Temporal Characteristics Of Zebrafish Cone Types And Their Role In Separate Visual Processing, Warren Patterson

Masters Theses & Specialist Projects

Chromatic and luminance information are processed separately by the visual systems of most higher vertebrates via anatomically separate pathways. Research on primates suggests that the luminance mechanism transmits information about stimulus luminance, movement, and flicker while chromatic mechanisms signal color and detailed information. In order to signal rapid movement, the luminance channel transmits information more rapidly than the chromatic mechanism. While some lower vertebrates such as the zebrafish (Danio rerio) do not demonstrate anatomical separation of processing, it is believed that separate processing is a basic requirement of vertebrate vision. The spectral sensitivity functions (relative sensitivity to different wavelengths of …


Using Biodata To Predict Alternative Measures Of Training Period Turnover, Ronald Pankratz Dec 1996

Using Biodata To Predict Alternative Measures Of Training Period Turnover, Ronald Pankratz

Masters Theses & Specialist Projects

Logistic Regression was utilized to add to what is known about biodata and turnover. Biodata items from 958 former and current employees in a manufacturing environment were used to develop models to predict a) which employees will turnover prior to completion of a ninety-day training period, b) who will leave voluntarily versus involuntarily, and of those who leave voluntarily c) which leavers are functional versus dysfunctional. A significant relationship was found between biodata items and completion of the ninety-day training period. The resulting model indicated that those who completed training were employed at time of hire, had higher aptitude scores, …

Specifically, this study examined whether there are differences, or, differential score changes between these populations from one test version to the next. Score changes were obtained from 7 school districts in Western Kentucky. Recorded were scores from the WISC-R and WISC-III administrations in the areas of Verbal, Performance, and Full Scale IQ scores. The information collected about the children included date of …


Examination Of Perceptions Of Procedural Justice When Establishing A Maternity Leave Policy In A University Setting, Sarah Leider Aug 1996

Examination Of Perceptions Of Procedural Justice When Establishing A Maternity Leave Policy In A University Setting, Sarah Leider

Masters Theses & Specialist Projects

Procedural justice in organizations has received increasing attention from researchers in recent years. Part of the reason for the increase in attention is that today's workforce must satisfy inner needs through aspects of the job that are not related directly to pay and promotion due to the current trend in downsizing organizations. As more women enter the workforce, the issue of maternity leave is also becoming more prevalent. More and more women are working in professional fields and don't want to end their careers in order to have and raise children. In this current study the researcher has combined the …

Information was gathered through an extensive search of the computer databases, Educational Resource Information Center (ERIC, 1966-1996) and PsycLIT (PsycINFO, 1973-1995) using key terms - such as temperament, behavior, behavior problems, rating scales, parental agreement, parent ratings, socioeconomic status (SES), gender, and congruence. Results of the search identified several factors that are associated with ratings. These were socio-economic status (SES), gender, and marital satisfaction/parental psychological status. An annotated bibliography and tables were created for the …


The Contribution Of Children's Peer Relations To Adjustment In An Ungraded Primary Program, Daniel Diehl Aug 1996

The Contribution Of Children's Peer Relations To Adjustment In An Ungraded Primary Program, Daniel Diehl

Masters Theses & Specialist Projects

While research in same-age classrooms has found a significant relationship between peer relations and school adjustment, little is known about the contribution peer relations makes to school adjustment in the mixed-age classroom. The purpose of the present study was to investigate the contributions that peer acceptance, social status, social behavior, and age relative to classmates make to children's attitudes toward school and their achievement in mixed-age (ungraded) primary classrooms. Children's attitudes toward reading, math, and science were positively related to reading, math, and science achievement scores. Children's achievement could be predicted from children's attitudes toward school and peer relations variables. …


The Effect Of Ses On Parent Ratings Of Termperament And Behavior, Heather Brown Aug 1996

The Effect Of Ses On Parent Ratings Of Termperament And Behavior, Heather Brown

Masters Theses & Specialist Projects

The present researcher examined the relationship of SES and parent agreement on ratings of temperament and behavior. Specifically, mother and father ratings were obtained on the Temperament Assessment Battery for Children-Revised (TAB-R) and Conners Parent Rating Scale-48 (CPRS-48) for a sample of 64 preschool children within low, middle, and high SES groups. Internal consistencies were established to be .70 or above on the majority of scales on the TAB-R and CPRS-48. The majority of correlations for mother and father ratings were moderate to high on scales of the TAB-R and CPRS-48, with each scale demonstrating significant, moderate correlations for the …


The Effect Of Child Gender On Parent Ratings Of Temperament And Behavior, Brent Beck Jul 1996

The Effect Of Child Gender On Parent Ratings Of Temperament And Behavior, Brent Beck

Masters Theses & Specialist Projects

Parent ratings of their children play a significant role in the assessment process. However, past research on rating scales has focused largely on teacher ratings. Less frequent studies on parent rating scales have predominant!}' used mothers' ratings and omitted fathers' ratings. In addition, research comparing parent ratings have produced inconsistent results when describing effects of gender of the child and rater. In this study, parents of 35 three to five-year-old preschoolers rated their child on the Temperament Assessment Battery for Children: Parent Form (T AB-R) and the Conners Parent Rating Scales-48 (CPRS-48). Adequate reliability for mothers and father ratings were …


The Encoding Of Frequency Information As An Automatic Process: A Quantitative Review, Kellie Goedart Jun 1996

The Encoding Of Frequency Information As An Automatic Process: A Quantitative Review, Kellie Goedart

Masters Theses & Specialist Projects

People use information on how often events occur as the basis for many decisions they must make. For example, it has been shown that people will credit a statement as being more true the more frequently they have heard it. Additionally, probability information derived from observations of the frequency of occurrence of events has been shown to play a role in concept formation. One of the primary controversies in the study of how individuals process frequency information revolves around the contention that the encoding of frequency information is an automatic process (one that requires little or no attentional capacity and …


The Autistic Child: Intervention Strategies, Kristie Jackson May 1996

The Autistic Child: Intervention Strategies, Kristie Jackson

Mahurin Honors College Capstone Experience/Thesis Projects

With autistic individuals, several intervention strategies have been developed--such as facilitated communication (FC), picture exchange systems, and sensory and auditory integration training--to help them relate to the world around them. Time and technology have indeed brought about many techniques for developing the communication skills of autistic individuals, but the tried-and-true behavior modification therapy (BMT) still proves to be the most effective. If other strategies do work, it is because behavior modification has been incorporated.


The Authoritarian Personality And Economic Distress, Kenneth Hinton Apr 1996

The Authoritarian Personality And Economic Distress, Kenneth Hinton

Masters Theses & Specialist Projects

In this study, I combined the personality and social indicator approaches of authoritarianism to determine if these separate approaches reflect similar constructs, and also examined whether economic distress increases authoritarianism and its internal coherence. The writer, in contrast with the time-series designs used in previous social-indicator studies, controlled for extraneous historical events by sampling individuals within the same time period. One hundred and sixty-one employed and 41 unemployed adult manufacturing workers completed a ninety-five-item questionnaire. The questionnaire contained a short version of the right-wing authoritarianism scale (RWA), items reflecting the social indicators of authoritarianism, and both objective (family income, employment …


Avoidance Behavior In The Elderly Driver, Mark Graves Apr 1996

Avoidance Behavior In The Elderly Driver, Mark Graves

Masters Theses & Specialist Projects

Do older drivers modify their driving habits in response to functional impairment? Older drivers who avoid challenging driving situations were compared with non-avoiders, to determine whether functional limitations were related to avoidance and whether avoidance is related to reducing crash risk. Results showed that, on the average, older drivers reported avoiding driving at night, on high traffic roads, on high speed roads, and in rush hour traffic while not avoiding left turns, driving in the rain, and driving alone. Subjects were placed into groups based on their cognitive and visual abilities. It was found that older drivers with an impaired …
