Age-Related Dendritic Changes In Human Occipital And Prefrontal Cortices: A Quantitative Golgi Study, Kelly A. Courns, Bob Jacobs Jan 1996

Age-Related Dendritic Changes In Human Occipital And Prefrontal Cortices: A Quantitative Golgi Study, Kelly A. Courns, Bob Jacobs

Modern Psychological Studies

Qualitative (Scheibe!, 1992) and quantitative (Jacobs & Scheibel, 1993) research indicates a general decline in dendritic neuropil with increasing age. The present study extends previous human dendritic research by examining quantitatively age-related changes in 2 cortical areas: prefrontal cortex (area 10) and occipital cortex (area 18). Tissue blocks were obtained from the left hemisphere of 10 neurologically normal subjects, ranging in age from 23 to 81 years. Blocks were stained with a modified rapid Golgi technique. Supragranular pyramidal cells were quantified on a Neurolucida computer/microscope interface system (Microbrightfield, Inc.). Dendritic system complexity was determined by several dependent measures: total dendritic …


Symbolic Interaction And An Interpretive Approach To Cross Cultural Psychiatry, Henry Dyson Jan 1996

Symbolic Interaction And An Interpretive Approach To Cross Cultural Psychiatry, Henry Dyson

Modern Psychological Studies

Adoption of the medical model of psychopathology has de-emphasized the need for psychiatry to incorporate new developments from the other social sciences. The need for an interpretive (rather than merely biological) approach to psychopathology based upon theories of symbolic interaction is argued in the present article with respect to the emerging field of cross-cultural psychiatry. Groundwork for such an approach is sketched out by application of Obeyesekere's (1981) anthropological theory of personal symbols.


Exploring Three Correlates Of Thought Suppression: Attention, Absorbtion, And Cognitive Load, Carolyn I. Vicchiullo, Dana S. Dunn Jan 1996

Exploring Three Correlates Of Thought Suppression: Attention, Absorbtion, And Cognitive Load, Carolyn I. Vicchiullo, Dana S. Dunn

Modern Psychological Studies

Previous studies evaluating the probability of successful thought suppression (attempts to rid our minds of repeated unwanted thoughts) have relied solely upon internal mental distracters (Wegner, 1989), characterizing thought suppression to be a controlled rather than an automatic process. As an alternative approach, the effects of attention actively focused on limited external stimuli were studied in order to achieve easy, effortless, and successful thought suppression. Participants included students enrolled in undergraduate psychology courses. Experiment 1 showed that the presence of cognitive load (computerized tests of perceptual skills) occupied conscious capacity sufficiently so that attempts to suppress both mundane (tree) and …


Apathy Correlates With Self-Esteem: A Study Of Personality, Orie Kristel Iv, Jen Young, Kate Ruley, Laura Seidel, Denise Krch, John Nonnemacher, David Helfand, Shawn Ogiba Jan 1996

Apathy Correlates With Self-Esteem: A Study Of Personality, Orie Kristel Iv, Jen Young, Kate Ruley, Laura Seidel, Denise Krch, John Nonnemacher, David Helfand, Shawn Ogiba

Modern Psychological Studies

To study apathy and the variables that influence it, a psychological research methods class from a small, liberal arts, northeastern college devised a 10 item questionnaire. The questionnaire included a student designed apathy scale, a Locus of Control scale, a Self-Esteem scale, and a number o f demographic questions. The hypothesis that high apathy levels would be con-elated with low self-esteem and an external locus of control was supported. The discussion argues that learned helplessness may contribute to the apathy scores and may be the "common denominator" underlying student apathy, low self- esteem, and external locus of control.


Effect Of Music Speed On Latency Of A Motor Task, Margaret M. Schneider Jan 1996

Effect Of Music Speed On Latency Of A Motor Task, Margaret M. Schneider

Modern Psychological Studies

To investigate the effect of music on the latency of a motor task, 36 participants were randomly assigned to three groups: the fast music group, the slow music group, and the no music group. Participants separated 200 colored beads by color while they listened to Preludium in E major played at 208 beats per minute, Air from orchestra suite No.3 played at 58 beats per minute, or music. The latency to complete the task was measured by recording time in units o f seconds. Participants in the slow music group took significantly more time to complete the motor task (M …


Development Of The Prosocial Personality At Work Scale, Antonia P. Steward, Sue Falter Mennino, Barbara A. Fritzsche Jan 1996

Development Of The Prosocial Personality At Work Scale, Antonia P. Steward, Sue Falter Mennino, Barbara A. Fritzsche

Modern Psychological Studies

This study was aimed at developing a scale to measure prosocial behavior in a work-related context that may predict Organizational Citizenship Behaviors (OCBs). The Prosocial Personality at Work Scale (PPWS) items were developed by adding a work-related frame-of-reference to items from the Prosocial Personality Battery (PSB; Penner, Fritzsche, Craiger, & Freifeld, 1995), a general measure of prosocial personality. In addition, some new items were generated. A sample of 55 participants completed the initial 14 item version of the PPWS. After an item analysis was performed and revisions made, a new sample of 99 participants anonymously completed three measures consisting of …


The Cyclical-Interaction Model: How Phobia Onset Disrupts Normal Cognitive Processing, Maryl Barton Jan 1996

The Cyclical-Interaction Model: How Phobia Onset Disrupts Normal Cognitive Processing, Maryl Barton

Modern Psychological Studies

A growing body o f cognitive research indicates that there is likely to be a cognitive basis for the onset, development, and maintenance of phobias. This possibility is examined relative to the potential for phobias to disrupt normal cognitive processing. Both the behavioral and cognitive approaches to the understanding and treatment o f phobias are explored. A hypothetical model is presented in which areas of cognitive disruption via phobia onset are explored, and a hypothetical case is presented to illustrate the new model. Implications of the new model for pursuing better phobia treatments, and the possible application of this model …


Effects Of Media-Endorsed, Thin-Ideal Body Image On Women's Self-Esteem, Anne E. Stuart Jan 1996

Effects Of Media-Endorsed, Thin-Ideal Body Image On Women's Self-Esteem, Anne E. Stuart

Modern Psychological Studies

The present study examines the effects of the media-endorsed, thin-ideal body image on women's self- and body- esteem. Participants in this study were 63 undergraduate females ages 18 to 21. Participants viewed slides of either "ideal-body" images or "neutral" images. Self- and body-esteem were evaluated using the Rosenberg Self Esteem Scale, the Body Esteem Scale, and the Body Image/Attractiveness Perception Scale. Contrary to previous research in this area, no significant differences were found between participants in the two conditions. Explanations for the lack of difference are discussed, and suggestions for future research are presented.


Mothers' Parenting Styles And Their Daughters' Eating Disorders, Tania D. Little, Ruth H. Lindow-Cook, Ramona E. Tolliver, Tamela L. Sise Jan 1996

Mothers' Parenting Styles And Their Daughters' Eating Disorders, Tania D. Little, Ruth H. Lindow-Cook, Ramona E. Tolliver, Tamela L. Sise

Modern Psychological Studies

Past research concerning the mother-daughter relationship and eating disorders provided compelling evidence that such a relationship exists. This study used Baumrind's three styles of parenting: authoritative, authoritarian, and permissive (Buri, 1991; Benokraitus, 1993). Sixty female college students, ages 18 to 22, were assessed using Buri's (1991) Parental Authority Questionnaire (PAQ), and assigned to groups, either authoritative, authoritarian, or permissive, depending on their mothers' parent- ing styles. The Eating Disorder Questionnaire (EDQ; Little, Lindow-Cook, Tolliver, & Sise, 1996) was administered to all groups. Analysis using multiple regression, R = .373, (R2 = .139), and ANOVA found significance (F [2,60] = 4.607, …

The Role Of Gender In The Processing Of Dating Scripts, Krista M. Reed, Lea T. Adams Sep 1995

The Role Of Gender In The Processing Of Dating Scripts, Krista M. Reed, Lea T. Adams

Modern Psychological Studies

The issues under investigation were gender differences in either content or memory discrimination of dating scripts and general examination for differences in memory of typical and atypical events using the script pointer plus tag (SP+T) hypothesis. A total of 52 female and 54 male undergraduates participated. Subjects were enrolled in introductory psychology classes at a large midwest university and were primarily Caucasian, single, and between the ages of 18-21 years. In Phase 1 and Phase 2 of the study, items that would possibly occur in 4 different dating scenarios were generated and then rated for typicality. Males and females both …


The Effect Of The Nmda Noncompetitive Antagonist Ketamine On Serial Learning In Rats, Brooks Snider, David M. Compton, Robert Foster Sep 1995

The Effect Of The Nmda Noncompetitive Antagonist Ketamine On Serial Learning In Rats, Brooks Snider, David M. Compton, Robert Foster

Modern Psychological Studies

Past research has demonstrated that Nmethyl- D-aspartate (NMDA) receptor antagonists disrupt the acquisition of a variety of spatial and non-spatial tasks. In the present investigation, the effects of the NMDA antagonist, ketamine, were examined in a task with minimal spatial demands. Twenty-six male Long-Evans rats, approximately 5 months of age at the beginning of training, served as the subjects. Before training began, all rats were reduced to 85% of their free feeding weight and maintained with this 15% reduction throughout training. After injections of ketamine or saline, rats were trained to respond in a runway to a nonmonotonic serial pattern …


Recovery From Stroke Involving The Left Middle Cerebral Artery, Lori Walter Sep 1995

Recovery From Stroke Involving The Left Middle Cerebral Artery, Lori Walter

Modern Psychological Studies

The rehabilitative treatment of a 73-yearold male who suffered from a left middle cerebral artery (MCA) thrombotic infarct was observed to analyze the effects of age and psychological and social factors on stroke recovery. The patient was assessed as having minimal verbalization, right side neglect, right hemiparesis, right hemisensory deficits, decreased balance and mild dysphasia. After 29 days of physical therapy, occupational therapy, and speech therapy, he showed improvement in activities of daily living, walking, and communication. He was discharged 33 days poststroke (DPS). Age of the patient and severity of the stroke seemed to be poor predictors of stroke …


Glucagon Produces Delayed Increase In Drinking-Associated Food Intake, Brian A. Carr, Paul J. Kulkowsky Sep 1995

Glucagon Produces Delayed Increase In Drinking-Associated Food Intake, Brian A. Carr, Paul J. Kulkowsky

Modern Psychological Studies

Glucagon is a pancreatic hormone and a brain-gut peptide thought to function as a short-term satiety signal in control of food intake. This study examined effects of glucagon injection on intake of alcohol, food, and water. Overnight water-deprived female and male Wistar rats (Ns = 10) were given access to 5% w/v ethanol and Purina chow. After adaptation to this schedule, rats received intraperitoneal (ip) injection of 0, 200, or 400 g/kg of glucagon, at 0 or 30 min prior to alcohol access. Food intake was significantly increased by glucagon at 30-60 min after either time of injection (0 or …


Self-Protective Attributions In Stigmatized Individuals, Theodore Harding, Dorothee Dietrich Sep 1995

Self-Protective Attributions In Stigmatized Individuals, Theodore Harding, Dorothee Dietrich

Modern Psychological Studies

Research has shown that stigmatized subjects, defined as members of groups about which others hold negative attitudes, receiving negative feedback from a prejudiced evaluator attribute the nature of the feedback to the source rather than to their own performance. The purpose of this experiment was to determine whether this self-protective mechanism also occurs in nonstigmatized individuals. Sixty-seven subjects, male and female undergraduate students enrolled at a small midwestern liberal arts college, participated in a 2 x 2 between-subjects factorial design in which the independent variable of evaluator prejudice or nonprejudice was crossed with stigmatized or nonstigmatized subject status. Results of …


Students' Sophistication Level And Confidence In Testing Procedures Predicts Susceptibility To The Barnum Effect, Thomas R. Rutledge Sep 1995

Students' Sophistication Level And Confidence In Testing Procedures Predicts Susceptibility To The Barnum Effect, Thomas R. Rutledge

Modern Psychological Studies

The present study examined the relationship between students' level of sophistication and confidence in personality assessment procedures with their susceptibility to the Barnum effect— the tendency for individuals to accept highly generalized, ambiguous profiles as accurate descriptions of their personality. Thirty-five university students (22 females, 13 males, mean age 26) completed a brief personality questionnaire under the impression they would be receiving an interpretation from a) a masters level clinician, b) a clinical psychologist (PhD), or c) a form of computer assessment. A pretest asking for the subject's age, sophistication, and their perceptions of the three assessment sources accompanied the …


A Quantitative Dendritic Analysis Of Four Functionally Distinct Areas Of Human Cerebral Cortex, Serapio M. Baca, Bob Jacobs Sep 1995

A Quantitative Dendritic Analysis Of Four Functionally Distinct Areas Of Human Cerebral Cortex, Serapio M. Baca, Bob Jacobs

Modern Psychological Studies

Recent investigations have begun to elucidate the function of dendritic arbors, revealing that the geometry of dendrites and the presence of dendritic spines play important roles in both simulated and actual dendritic function (Midtgaard, 1994). The present study attempts to correlate dendritic complexity with cortical function under the assumption that connectivity in a local cortical area may determine its more holistic functional properties. Two human brains (ages: 23 and 69 years) were used for the present study. Four cortical areas (Brodmann's [1908] areas 3, 1, and 2; area 22; area 44; and area 10), respectively representing Benson's four levels of …


The Effects Of A Standardized Ginkgo Bilboa Extract On Learning In Aged And Young Rats, Scott Heldt Sep 1995

The Effects Of A Standardized Ginkgo Bilboa Extract On Learning In Aged And Young Rats, Scott Heldt

Modern Psychological Studies

The effects of chronic oral administration of a standardized Ginkgo biloba extract (GBE) on the performance of two classical memory tasks was investigated. Long-Evans rats, 3 and 16 months of age, received daily doses of diets with or without GBE (100 mg/kg) for a period of 6 weeks before testing and throughout the experiment. A 2 x 2 (Age x Treatment) ANOVA indicated that GBE treatment prevented learning on a radial maze task as measured by number of days to criterion, F(1, 28) = 5.73, p < .05. A 2 x 2 x 19 (Age x Treatment x Day) ANOVA was used to analyze the number of correct responses from Days 1 to 19. The results showed an interaction between Age and Treatment F(1, 28) = 6.34, p <. 05; namely young treated rats performed worse than other groups. Analysis of response frequency by a 2 x 2 (Age x Treatment) ANOVA revealed a significant interaction F(1, 28) = 4.41, p < .05, and a subsequent post hoc test indicated that the young treatment group responded notably more than the old groups. Measured performance on a one-way passive avoidance task indicated that neither treatment nor age had an effect. The results suggest that at the prescribed dose level and duration, GBE impairs performance on a radial maze task, particularly in young rats.


The Child Sexual Abuse Interview: An Exploratory Evaluation Of Recommended Interview Components And Tennessee Department Of Human Service Interviews, Kirstin L. Elliott May 1995

The Child Sexual Abuse Interview: An Exploratory Evaluation Of Recommended Interview Components And Tennessee Department Of Human Service Interviews, Kirstin L. Elliott

Masters Theses and Doctoral Dissertations

A direct consequence of the increasing number of reported cases of child sexual abuse is an influx of court cases involving allegations of sexual abuse. These allegations are accompanied by investigative interviews of the parties involved in the cases, including the alleged child victims. It is imperative that the investigative interviewing process be objective and reliable enough to be admissible in court in order for justice to be served in the best interests of the child through the due process of law. Cases such as the infamous McMartin trial (People v. Buckey, 1984), which ended in a hung jury after …

The Effects Of Sodium Salicylate On Sexual Arousal In Adult Male Mice (Mus Domesticus), Andrew S. Manos Jan 1995

The Effects Of Sodium Salicylate On Sexual Arousal In Adult Male Mice (Mus Domesticus), Andrew S. Manos

Modern Psychological Studies

Adult male rats produce 22-kHz vocalizations when exposed to a female conspecific. These ultrasonic vocalizations (USV) are a measure of the male's level of sexual arousal. Previous studies have shown that antipyretic drugs diminish the amount of USV made by male rats. Male mice also emit USV (70- kHz) indicative of sexual arousal. In this study, the effects of sodium salicylate, an antipyretic drug, were examined to see if USV were diminished in mice. Fifteen male adult mice were tested in a Treatment (Saline vs. Sodium Salicylate) x Dose (High vs. Low) design, with repeated measures across the treatments. Vocalizations …


The Bilateral Field Advantage On Verbal And Nonverbal Matching Tasks, Jennifer Reyburn Jan 1995

The Bilateral Field Advantage On Verbal And Nonverbal Matching Tasks, Jennifer Reyburn

Modern Psychological Studies

Three experiments examined the bilateral field advantage (BFA) on both verbal and nonverbal matching tasks. The goal of the experiments was to determine which conditions would maximize the size and reliability of the BFA, and thus enhance its value as a possible diagnostic tool to assess callosal dysfunction. In Experiment 1, 27 right-handed college students performed two matching tasks (order of tasks varied across subjects; dots-letters, letters-dots, or letter and dot trials randomly interleaved). Results revealed a verbal BFA in all task order conditions (p<.01), but a significant nonverbal BFA only in the interleaved condition (p<.01). Experiments 2 and 3 reproduced the interleaved condition with different parameters. In both experiments the verbal BFA was significant (p<.01), but nonverbal BFA was significant only when four-dot patterns were used (p<.05). Results suggest the interleaved presentation of verbal and nonverbal stimuli is a reliable method of measuring the BFA.


Pluralistic Ignorance Concerning Alcohol Usage Among Recent High School Graduates, Jill S. Braddock, Tonia R. Wolf Jan 1995

Pluralistic Ignorance Concerning Alcohol Usage Among Recent High School Graduates, Jill S. Braddock, Tonia R. Wolf

Modern Psychological Studies

Recent high school graduates in a midwestern community estimated their classmates' attitudes toward alcohol use in contrast to their own positions. Attitudes were assessed on three levels: subjective comfort with others' drinking, approval of peer drinking and actual drinking practices. Pluralistic ignorance was found to be a significant factor at all three levels, p < .0005. Respondents reported that they were less comfortable, less approving, and drank less than close friends, lesser still than friends, and far less than peers. These findings provide support for "normative education" prevention programs that attempt to correct erroneous perceptions about alcohol use and abuse.


An Overview Of Parallel Distributed Processing, Jonathan P. Heyl Jan 1995

An Overview Of Parallel Distributed Processing, Jonathan P. Heyl

Modern Psychological Studies

Parallel Distributed Processing (PDP), or Connectionism, is a frontier cognitive theory that is currently garnering considerable attention from a variety of fields. Briefly summarized herein are the theoretical foundations of the theory, the key elements observed in creating simulation computer programs, examples of its applications, and some comparisons with other models of cognition. A majority of the information is culled from Rumelhart and McClelland's (1986) two volume introduction to the theory, while some concerns from the field and the theorists' accompanying responses are taken from a 1990 article by Hanson and Burr.


Attachment And First Sexual Experience, Chrystal Goings-Vogelsang Jan 1995

Attachment And First Sexual Experience, Chrystal Goings-Vogelsang

Modern Psychological Studies

This investigation examined the relationship between first sexual experience and attachment tendencies. Subjects' first sexual experiences were examined as a function of Bartholomew's four attachment categories: secure, fearful, preoccupied, and dismissing (Bartholomew & Horowitz, 1991). It was hypothesized that if a person's first sexual experience was negative, then he or she would score significantly lower on the secure attachment subscale. Results indicated (a) that college females who had a fearful attachment style were more likely to report that their first sexual partner pressured them into sex, b) that college females who were more dismissing in their attachment style were less …


Spontaneous Alternating Behavior, Attention, And Exploration: The Effects Of Colchicine Lesions In The Rat Hippocaompal Formation, David E. Wagoner Jr., Zhenique M. Israelian Jan 1995

Spontaneous Alternating Behavior, Attention, And Exploration: The Effects Of Colchicine Lesions In The Rat Hippocaompal Formation, David E. Wagoner Jr., Zhenique M. Israelian

Modern Psychological Studies

This study investigated perseverative behavior, attention, and exploratory behaviors via discrete lesions of the rat hippocampal formation. It was hypothesized that lesions which interrupted input to the hippocampus and output to cortical and subcortical regions would induce these behaviors. Forty-four male Long-Evan rats were randomly divided into four treatment groups: cerebral spinal fluid, and three colchicine lesioned groups, 10-COL, 15-COL, and 25-COL. The animals were compared based upon performance in a standard Tmaze to test perseveration. Behaviors were also observed in an activity chamber to measure locomotion, attention, and exploration. Animals in the 25-COL group demonstrated a significant increase in …


Memory Decrement And Proactive Interference, William J. Thornton, Bennett L. Schwartz Jan 1995

Memory Decrement And Proactive Interference, William J. Thornton, Bennett L. Schwartz

Modern Psychological Studies

We hypothesized that subjective expectations were responsible for the release from proactive interference (PI) rather than the actual change in taxonomic subcategories. The experimental conditions included informing or not informing subjects of the change in taxonomic subcategory, crossed with whether the taxonomic subcategory was actually changed or remained unchanged. The interest in whether a release would be seen when the subjects were informed of a change, yet no change was actually administered, was most specific. Significantly higher recall was found for the condition in which subjects were informed of a change, but no actual change occured (I-NC) than in the …


Memory For Frequency Of Complex Sounds, Jennifer R. Lewis Jan 1995

Memory For Frequency Of Complex Sounds, Jennifer R. Lewis

Modern Psychological Studies

This study examined whether different testing conditions hamper or enhance the ability to remember frequency of events. Subjects were presented a series of computerized sounds during the acquisition phase and estimated during the testing phase how many times they had heard each sound. Subjects were placed into one of four conditions: (a) no labeling, subjects simply listened to the stimuli; (b) labeling, subjects devised a description for each sound; (c) continuous distractor, subjects performed a simple mathematical task for the entire acquisition periods; and (d) intermittent distractor, subjects performed the mathematical task between the sounding of stimuli. Results indicated that …


Behavioral Effects Of Irreversible Dopamine Receptor Inactivation In The Preweanling Rat: Assessment Of The Receptor Reserve Hypothesis, Suzanne L. Reid, Sanders A. Macdougall Jun 1994

Behavioral Effects Of Irreversible Dopamine Receptor Inactivation In The Preweanling Rat: Assessment Of The Receptor Reserve Hypothesis, Suzanne L. Reid, Sanders A. Macdougall

Modern Psychological Studies

EEDQ is an irreversible receptor antagonist that eliminates the dopamine (DA) mediated behaviors of adults rats. In contrast, EEDQ does not seem to affect the DA mediated behaviors of preweanling rat pups. One explanation for this age dependent difference is that rat pups may have a DA receptor reserve, not available to adults, which is sufficient to mediate behavior. Therefore, the purpose of the present study was to determine whether a Di and D2 receptor reserve exists in preweanling rats. A total of 96, 17-dayold rat pups were injected with EEDQ (7.5 mg/kg) or its vehicle immediately after being trained …


Advertising Preferences When Presented With Various Ad Stimuli: The Impact Of Stereotypical Versus Non-Stereotypical Advertising, Jodi L. Bremer Jun 1994

Advertising Preferences When Presented With Various Ad Stimuli: The Impact Of Stereotypical Versus Non-Stereotypical Advertising, Jodi L. Bremer

Modern Psychological Studies

Past research has shown that the preferences for different types of advertising shift as social attitudes change. Whereas in the past people preferred advertising portraying men and women in gender-stereotypical roles, today's more liberal social attitudes seem to reflect a trend for people to prefer ads depicting those men and women in non-stereotypical gender roles. In the current study, 30 university students were tested for their preferences among stereotypical, nonstereotypical and neutral ads. Stimuli were 30 magazine advertisements, 10 each of the three types of ads, rated on a five point like-dislike scale, with higher scores reflecting greater ad appeal. …
