The Effects Of Test Validity Perceptions On Ethnic Group Differences In Cognitive Ability Test Performance, Florence R. Jinadu

Psychology Theses & Dissertations

Ethnic group differences in cognitive ability test performance have led to the problem of adverse impact for many organizations. In attempting to understand the cause of such differences, this study investigates the relationships among general test attitudes, test experiences, race, test validity perceptions, test knowledge, and cognitive ability test performance. A sample of undergraduate psychology students completed a paper-and-pencil test of cognitive ability as well as surveys of their attitudes towards employment tests and prior testing experiences. Participants in an experimental group received information that explained the validity and usefulness of employment tests for making selection decisions.

It was hypothesized …

A Comparison Of Cognitive Development Between Whites And African Americans Based On William Perry's Scheme Of Intellectual And Ethical Development, Joan Johnson

Theses and Dissertations in Urban Services - Urban Education

This study compared cognitive complexity between student groups based on cultural background and academic class utilizing William Perry's (1970) cognitive theory of intellectual and ethical development. In addition, the study examined the influence of gender and socioeconomic status (SES) on cognitive development. The goal was to ascertain whether Perry's theory, developed from his research on a relatively homogeneous college student population without consideration of the impact of a culturally diverse environment, would be valid for culturally diverse students.

The research design employed to investigate cognitive development used a cross-sectional sample of entering freshmen and graduating seniors attending a predominantly White, …

Does Wisdom Really Come With Age?: Cognitive Differences Between Traditional And Nontraditional Aged College Women, Kelli Jean England

Psychology Theses & Dissertations

Nontraditional aged (age 25 and over) college women outperform traditional aged (age 18-24) college women academically. This research reviewed areas of differences in the two groups and proposed that differences in two main areas contribute to performance: motivation and cognitive maturation. One hundred and twelve female traditional and nontraditional aged students completed Mehrabian's Achieving Tendency Scale (MATS), the Watson-Glaser Critical Thinking Appraisal (WGCTA), and the Learning Environment Preferences measure (LEP). Students were identified as traditional aged (18-24 years), younger nontraditional aged (25-31 years), and older nontraditional aged (& 32 years). Grade point average (GPA) was used as a measure of …

The Effect Of Ethanol And Hypoglycemia On Rat Performance In The Radial Arm Maze, Monica Ann Gaffney

Psychology Theses & Dissertations

Both hypoglycemia (HG) and ethanol (ETH) intoxication can cause serious impairment in physiological and psychological functioning. Their combination could cause more severe cognitive impairment than either condition alone. This experiment investigated the effects of hypoglycemia, ethanol intoxication, and their combination on rat radial arm maze performance. Eleven male rats were trained to a stable, low error rate performance in achieving food rewards in an eight arm radial arm-maze. Rats were then given either insulin (2 units/kg) or saline in combination with ETH doses of 250, 500, 1000, or 1500 mg/kg 20 minutes prior to the maze run. Treatment order was …

Fostering The Development Of Domain-General, Nonlinear Mental Models: A Foundation For Systemic Thinking, Jeffrey S. Sinn

Psychology Theses & Dissertations

Two experiments examined whether people can develop a domain-general, nonlinear mental model when provided with an appropriate conceptual model. Both experiments presented causal loop models (i.e., variables connected in a circle by arrows representing causal relationships) as a conceptual model for positive feedback. Study 1 found that participants trained in causal loop modeling could accurately represent scenarios of low but not high complexity. Study 2 expanded on the design of Study 1 by varying the type of training and type of aid presented during testing. Participants received training with modeling instruction, training with cue-utilization instruction (i.e., participants were trained to …

The Measurement Of Mood Variation Over Time And Its Relation To Career Decision-Making Self-Efficacy In Young Adolescents, William Thomas Pinkston

Theses and Dissertations in Urban Services - Urban Education

Variation in mood states over time and the relationship between mood states and career decision making self-efficacy in young adolescents were investigated using the Profile of Mood States (POMS), the Multiple Affect Adjective Check List - Revised (MAACL-R), the Rotter's IE locus of control test, and the Career Planning Confidence Scale (CPCS). These tests were administered twice a week for six weeks. A correlational analysis was performed. The results showed a higher correlation between mood state measures as the subjects' moods varied over time than between either mood measure and locus of control which did not covary with either of …

Structural Equation Modeling Of Attitudes Toward Employment Testing, Laura Susan Hamil

Psychology Theses & Dissertations

This research investigated the relationships among past testing experiences, testing attitudes, perceptions of test performance, race, and gender. In addition, the effects of testing information on testing attitudes were studied. Two hundred and twelve applicants to a variety of positions in a large telecommunications company were asked to complete a series of questionnaires before and after employment testing. The questionnaires included measures of testing experience, general and specific testing attitudes, and perceptions of test performance. Scores on the employment test were also obtained as a measure of cognitive ability. Of the 212 participants, half were given a brochure to read …

Effects Of Goal Reward And Feedback Frequency On Motivation: A Control Theory Perspective, Jonathan Michael Balcerek

Psychology Theses & Dissertations

The current study investigated the effects of feedback frequency and goal reward on subject motivation. Klein's (1989) control theory model of work motivation was used to conceptualize the method and hypothesis. Subjects performed a simple computer addition task. When we examined subjects who displayed medium to high mathematical ability, significant effects were discovered. Higher goal reward led to higher motivation. In addition, subjects with a low goal reward and high amounts of feedback displayed lower motivation than subjects with a high goal reward and high amounts of feedback and subjects with a high goal reward and low amounts of feedback. …

The Influence Of Time Pressure And Information Load On Rule-Based Decision-Making Performance, Brooke Browne Schaab

Psychology Theses & Dissertations

Performance was evaluated under varying levels of time pressure and information load to determine their influence on simple rule-based decision-making. Consistent errors, biases, and heuristics found in human decision-making have been attributed to attempts to reduce attentional demands and to the limitations of working memory. Do these same mistakes occur when little or no demand is placed on working memory and the decision is made by following a set of simple rules? Using a simulation of a radar operator's task, 96 participants monitored a display for 24 min. Time pressure was manipulated by increasing or decreasing the number of aircraft …

Neuropsychological Assessment Of Battered Women, Mona Matheney Tiernan

Psychology Theses & Dissertations

This study examined the effect of physical battering on the neuropsychological functioning of women. Twenty-five battered women and twenty-five non-battered women were administered a neuropsychological screening battery (11 separate tests, yielding 16 variables) to assess for possible deficits in the areas of attention/concentration, memory, visual-perceptual skills, sensory-motor skills, novel problem solving, and verbal fluency. All participants completed a demographic questionnaire, a post-concussive syndrome checklist, and a questionnaire evaluating for the presence of depressed mood and possible effects of depression. Potential participants with a history of previous head injury (occurring from a source other than battering) or other neurological disorders were …

Animal-Word And Sound Test: An Auditory Cognitive Interference Effect, Jason L. Parker

Psychology Theses & Dissertations

This study presented a method in which the Stroop Color Word Test can be adapted to an auditory form. This auditory test used a series of animal words, animal sounds and word-sound combinations. This "Animal-Word-and-Sound test" contained three subtests. The test tasks were to repeat a list of words, identify a list of animal sounds, and to identify the sound in a combined animal word-sound pairings (Both the animal's name and sound are presented simultaneously). An alternate form of this audio test was examined. The alternate form followed the same construction except in the final condition, the task was to …

Body Image And Information-Processing Biases On A Modified Stroop Task, Andrea Powell Arcona

Psychology Theses & Dissertations

Recent research in the area of body image and body-image disturbance has increasingly examined cognitive information-processing models. The focus of the current study was on the processing of appearance-related and nonappearance-related information in appearance-schematic versus appearance-aschematic women. As a modified and extended replication of a study by Labarge, Cash, and Brown (in press), information processing was investigated using a computerized Stroop-type task. Participants were 128 Old Dominion University women who had previously completed the Appearance Schemas Inventory (ASI). They were divided into two groups based on their above median (appearance-schematic) or below-median (appearance-aschematic) ASI scores, Then, at designated times, these …

The Effects Of Simultaneous And Successive Tasks And Knowledge Of Results On Add And Non-Add Children, Pamela J. Bishop

Psychology Theses & Dissertations

Computerized continuous performance tasks (CPT) are often used to diagnose attention deficit disorders (ADD) The purpose of the present study was to continue the evaluation of a CPT developed from a psychophysical perspective. Specifically, two versions of a monitoring task (simultaneous and successive) were examined in the context of three conditions of knowledge of results (KR); KR to correct detections, false alarms, and irrelevant KR. Thirty children diagnosed with ADD and 30 without ADD performed two 9-minute monitoring tasks. Parents of the children were also interviewed with an adaptive behavior scale to investigate whether ADD children exhibit social functioning at …

Attentional Processing Of Visual Stimuli: What Makes A Face A Face?, Samuel L. Chapman

Psychology Theses & Dissertations

Reaction time (RT) and accuracy have been used to investigate the manner in which humans process visual stimuli for many years. Some researchers have found evidence of serial processing (e.g., Sternberg, 1969a) while others have shown that some visual stimuli are processed in parallel (e.g., Neisser, 1963). There have been very few studies investigating the processing of schematic faces with respect to RT and accuracy. The present study investigates the mechanisms associated with the recognition of schematic faces with respect to RT and accuracy.

Forty-two Old Dominion University students were shown a target face for ten seconds and were then …

Conjunctive Decisions In A Paper-And-Pencil Task, Tracy A. Bean

Psychology Theses & Dissertations

Many situations can have a significant effect on response time. Some situations affecting response time require union decisions - decisions based on the 'or' rule. The Hick-Hyman law, as well as Sternberg's linear relationship, are based on union decisions. Most situations in the real world, however, are based on intersection or 'conjunctive' decisions - decisions based on the 'and' rule. The relationship between conjunctive decisions and reaction time is examined in the present research. One question this study attempted to answer is whether there is a functional relationship between mean response time and display size.

The study consisted of 139 …

Judging Statistical Significance: The Effects Of Standard Error Bar Formats And Visual Displays, Rebecca Wilson Miller

Psychology Theses & Dissertations

The present study examined various graphical displays for illustrating statistical significance. These displays were created following Dunlap and May's (1989) recommendation about representing statistical significance in figures with error bars derived from the pooled estimate of error variance. In the first experiment, 15 graduate students were asked to judge whether the relationships depicted in a series of graphs and tables were significant or nonsignificant. Four significance levels were combined factorially with three standard error bar formats, unidirectional opposite direction, unidirectional same direction, and bidirectional, and two displays, line graphs and bar graphs. A tabular display was also presented for comparison. …

Visual Information Processing Of Geometric Figures As A Function Of Complexity And Field Of Vision, Karen E. Inn

Psychology Theses & Dissertations

The purpose of this study was to investigate whether human information processing does occur in parallel in the right hemisphere and serially in the left hemisphere as suggested by the hemisphere strategy model. In addition, this study was also designed to determine if there is a right hemisphere advantage in the processing of nonverbal information as indicated by the material specific theory.

In this 3 x 3 x 3 x 2 x 2 mixed design, Complexity (3) and Gender (2) were the between-subjects variables. Time Factor (3), Field of Vision (3), and Type (2) were the within-subjects variables. Complexity was …

Choice Reaction Time And Conjunctions Of Form Size Color And Orientation, Cristina Bubb-Lewis

Psychology Theses & Dissertations

Reaction time (RT) is frequently used as a dependent measure in studies that examine the organization of perceptual and cognitive processes. Hick's law states that RT in a choice-reaction-time (CRT) task is a linear function of the amount of information transmitted per stimulus-response event. RT has been used to try to determine whether serial or parallel processing is being employed in CRT tasks (Sternberg, 1966). There is research evidence suggesting a serial, exhaustive search process (Sternberg, 1969a; Wingfield, 1973), as well as findings which suggest parallel processing (Neisser, 1963; Neisser, Novick, and Lazar, 1963) in CRT tasks. All the experiments …

Choice Reaction Time As A Function Of Set Size And Signal Frequency, Barbara M. Herzing

Psychology Theses & Dissertations

This research was conducted in two experiments. The first experiment assessed whether set size for the negative and positive sets affected reaction time during a visual scanning task. The effects of signal frequency on these relationships were assessed in the second experiment. It was hypothesized that as set size increased, reaction time would increase. In addition, as signal frequency increased, it was hypothesized that reaction time would decrease. In the first experiment, 12 groups of 10 subjects each were tested varying the number of stimuli for the positive and negative sets. The second experiment tested 18 groups by varying the …

The Effects Of Stroke On The Comprehension Of Affective And Nonaffective Prosody, Mona Matheney Tiernan

Psychology Theses & Dissertations

The purpose of the present study was to examine the effects of stroke on the comprehension of prosody. Thirty two inpatient volunteers (16 with right hemisphere and 16 with left hemisphere stroke) and 16 controls participated in the study. A 3(Group) x 2(Gender) x 2(Task) mixed design was used. The independent variables were the subject group, gender and the prosody task (affective or nonaffective). The dependent variables were the percentage of correct responses to the affective and nonaffective prosody tasks. A 3(Group) x 2(Gender) x 2(Task) AN0VA revealed a significant main effect for group, E

About Faces: The Investigation Of Electrodermal Activity (Eda) As It Relates To The Recognition And Naming Of Faces, Donald J. Shearer

Psychology Theses & Dissertations

This study investigates and replicates the occurrence of a "W" pattern or compound electrodermal activity (EDA) response as it relates to the perception and naming of faces first found in Shearer and Mikulka (1991). Thirty-four male and thirty-four female subjects were randomly assigned to two conditions. The two conditions were balanced for sex having 17 males and 17 females each. The subjects were each presented 40 facial stimulus slides and the accompanying EDA responses were recorded. In the experimental condition subjects were required either to name (identify) the face or give a "feeling of knowing" rating of the face. In …

The Effect Of Fear Of Success And Perceived Task Difficulty On Cognitive Performance, David Eugene Elkins

Psychology Theses & Dissertations

This study investigated the relationship of fear of success (FOS) and perceptions of task difficulty, their interactive effect on anagram and matrix-task performance and possible gender differences on these variables. A total of 226 students, 83 males and 143 females, participated in the study. FOS was measured by the administration of Zuckerman and Allison's (1976) Fear of Success Scale. Perceptions of task difficulty were manipulated by use of falsified normative data. Subjects therefore believed the upcoming task was either easy or difficult or the subjects were employed as controls. An anagram task and 12 items selected from Raven's Standard Progressive …

Task-Hemispheric Integrity Effect: Level Of Task Difficulty And Mental Workload In A Dual Task, Nancy E. Hite

Psychology Theses & Dissertations

The task-hemispheric integrity effect states that when a spatial and verbal task must be time-shared, superior performance would be obtained when the same hemisphere that processes information also controls the hand used to respond. The effect of increasing the level of task difficulty on an unstable tracking task on the concurrent performance of a dichotic listening task was investigated. The results indicated that performance on the unstable tracking task significantly deteriorated as task difficulty level increased in both single- and dual-task conditions. However, performance on both the unstable tracking task and the dichotic listening task was not influenced by hand …

The Effects Of Irrelevant Dimensions On The Predictive Value Of A Warning Signal, Ruth Justine Arnegard

Psychology Theses & Dissertations

Past research has neglected irrelevant dimensions of visual warning signals in choice reaction-time tasks. The present study examined the effects of an irrelevant dimension of a visual warning signal and that signal's value in predicting a response stimulus on choice reaction time. A warning signal, which was a geometric figure, appeared in the center of a VDT screen and was followed by one of two response stimuli (open circles). The predictive value of the warning signal was defined as the percentage of trials during which the warning signal accurately predicted the response stimulus by size and was manipulated in the …

Dual Task Performance: The Effects Of Task Emphasis And Ear Of Input, Pamela R. Jordan

Psychology Theses & Dissertations

This experiment explored the lateralization of the processing of spatial and verbal information during dual-tasks. This study also investigated the relationship between right ear advantage and spatial ability, degree of handedness, and degree of familial handedness. Thirty-two male subjects performed a spatial rotation task and a dichotic listening task. During half of the dual tasks, subjects concentrated on both tasks equally. During the other half of the dual trials, 16 subjects emphasized the spatial processing task and 16 subjects emphasized the dichotic listening task. The results of this experiment do not support either the independent-hemispheric resources or the task-hemispheric integrity …

The Impact Of Orientation Training On Spatial Cognition And Spatial Behavior In Elderly Shoppers, Elizabeth Ann Mathes

Psychology Theses & Dissertations

The present study focuses on the acquisition of spatial knowledge in a large-scale, novel environment and on the interrelationships among psychometric tests of imagery, psychometric tests of spatial abilities, and experimental tasks involving spatial knowledge. Forty elderly females were provided microspatial information by four means: cartography; videotape; verbal description; and verbal description with imagery instructions. Analyses of behavior in a simulated shopping task within a suburban shop­ ping mall revealed differences in performance only for efficiency in Route Selection task. Cartographic and verbal presentations resulted in greater efficiency than did verbal description with imagery instructions or video­ tape presentations. Supplemental …

The Effects Of Temporospatial Integration On Distance Estimations Of Young And Elderly Adults, Margaret Rowley-Bernicki

Psychology Theses & Dissertations

The effect of discontinuity on temporospati al integration in the accuracy of distance estimations was examined utilizing a slide presentation of a route. Participants were 60 young and 60 elderly adults who were randomly assigned to one of two conditions. The two conditions were determined by whether the subjects viewed the walk in a logically sequenced order or a pre-determined randomized order. Subjects viewed the walk twice and thereafter made a series of distance estimates between a series of preselected landmarks chosen by a different group of young and elderly adults. Additionally, subjects gave self-ratings on a twelve-item questionnaire to …

An Examination Of The Relationship Between Mental Resources And Performance Strategies, Douglas L. Miller

Psychology Theses & Dissertations

Based on the work of Klapp, Marshburn, and Lester (1983) and more generally on principles of the Multiple Resource Theory, it was proposed that human short-term memory consists of two mental resource channels, one that is tapped by span memory tasks and one tapped by immediate working memory tasks. It was further hypothesized that dual-task performance would be better under conditions where one of the component tasks tapped the proposed span memory channel and one tapped the proposed working memory channel, than when both tasks tapped the same channel. In addition, it was hypothesized that dual-tasks tapping the same memory …

Landmark Selection And Temporal-Spatial Integration: Macrospatial Abilities In Young Adults And Elderly Adults, Deans Haggerty

Psychology Theses & Dissertations

Groups of young adults and elderly adults participated in a study examining age-related changes in macrospatial cognitive abilities. Perceptual differentiation/selection abilities were tested using a Landmark Selection task, while temporal-spatial integration abilities were explored through the use of a Scrambled Route task. In the Landmark Selection task, subjects viewed a slide presentation of a walk and then chose the landmarks which best represented the walk. For the Scrambled Route task, after viewing a slide presentation of a scrambled walk, subjects made distance estimations involving pairs of selected landmarks. Also included were self-assessment scales of spatial abilities and two psychometric tests …

An Information Processing Approach To The Study Of Map Interpretation, Susan Vaughan Felton

Psychology Theses & Dissertations

Three variables involved in map interpretation (rotation, planar angle, and scale) were examined from an information processing perspective to determine whether they were characterized by serial, parallel, or a combination of serial and parallel processing. Sex differences in these processes were also examined. Participants viewed a series of pairs of slides depicting various combinations of rotations, planar angles, and scales, and were asked to determine whether the pair represented the same array viewed from a different viewpoint. Accuracy and response time were the dependent variables of interest. Results indicated that the number of manipulations that were involved in a problem …
