The Temporal Context Model In Spatial Navigation And Relational Learning: Toward A Common Explanation Of Medial Temporal Lobe Function Across Domains, Marc W. Howard, Mrigankka S. Fotedar, Aditya V. Datey, Michael E. Hasselmo

Psychology - All Scholarship

The medial temporal lobe (MTL) has been studied extensively at all levels of analysis, yet its function remains unclear. Theory regarding the cognitive function of the MTL has centered along 3 themes. Different authors have emphasized the role of the MTL in episodic recall, spatial navigation, or relational memory. Starting with the temporal context model (M.W. Howard and M. J. Kahana, 2002), a distributed memory model that has been applied to benchmark data from episodic recall tasks, the authors propose that the entorhinal cortex supports a gradually changing representation of temporal context and the hippocampus proper enables retrieval of these …

Wonderwise 4-H: Following In The Footsteps Of Women Scientists, Amy N. Spiegel, S. Kay Rockwell, Deanna Acklie, Saundra Wever Frerichs, Kathleen French, Judy Diamond

Department of Educational Psychology: Faculty Publications

Wonderwise 4-H: Women in Science Learning Kits, recently included in the National 4-H Curriculum Collection and widely tested by 4-H leaders, have positively affected youths’ perspectives on science, scientists, and scientific work. Adult leaders who used the multimedia, inquiry-based Wonderwise 4-H kits completed a Web survey describing the impact of the kits on youth. It indicated that the kits increased youth’s interest and understanding of science, broadened their view of scientists, and opened their eyes to the possibility of science in their own futures. More information about Wonderwise 4-H and downloadable activities are available at wonderwise.unl.edu.

The Relationship Between Body Image And Weight Maintenance In Community Women Enrolled In Weight-Loss Programs, Amy S. Collings

Master's Theses and Doctoral Dissertations

Research suggests that poor body image, low self-esteem, and depression may be associated with failure to maintain weight loss (Lean, 2000). However, definitive results are lacking, necessitating further research. Both successful and unsuccessful weight maintainers (N = 148) were recruited from weight-loss programs. Self-report measures on dimensions of body image, depression, and self-esteem were administered at baseline and a three-month follow-up. Results suggest that those with early-onset obesity have more body image dissatisfaction than those with late-onset obesity, which appears to be due to BMI differences between groups with the former having a higher BMI than the later. Other results …

Social Fields, Belief In Psi, And Their Effects On Mental Telepathy, Brandy Mcwhorter

Masters Theses

The current study was designed to explore two major issues involving the existence of mental telepathy. The first goal was the exploration of the relationship between psi ability, specifically mental telepathy, and belief in psi phenomena. In addition, the value of social field theory as an explanation and potential facilitator of telepathic communication was explored. A small group of research assistants attempted to telepathically send 1 of 4 target locations to large groups of participants acting as receivers. The receivers answered a question on a 7-point-scale indicating their level of belief in mental telepathy. Two separate runs of 16 trials …

The Effects Of Perceived Authority On Suggestibility In Interrogation-Like Situations: A Pilot Study, Renae Kotas, Derek Dehne

The Journal of Undergraduate Research

The effect of perceived authority on suggestibility was assessed. Two groups of participants were used, one receiving perceived authority and one receiving none. A military student dressed in fatigues administered the procedure to the first group and a civilian student in street clothes administered to the second. The Gudjonsson Suggestibility Scale was used to assess the suggestibility of each group. No significant difference between the groups was found.

Ethanol Effects On Reward Value Judgment Following Infusions Into The Amygdala: Implications For Emotional Processing, Stephanie M. Brewer '05

Honors Projects

Alcohol, when delivered systemically, leads to impaired performance on a variety of tasks, including emotionally-laden or reward value tasks. It is also known that lesions to the amygdala produce emotional or reward value deficits. However, it is unknown whether the emotional deficits observed after alcohol ingestion are due to alcohol's direct effect on the amygdala. The present study examined the effects of alcohol when infused directly into the amygdala on emotional memory and judgment. Eight male Long-Evans rats were trained on a behavioral task to associate one sweetness level with a reward and another sweetness level with no reward. Once …

Sequential Super-Stereotypy Of An Instinctive Fixed Action Pattern In Hyper-Dopaminergic Mutant Mice: A Model Of Obsessive Compulsive Disorder And Tourette's, Kent C. Berridge, J Wayne Aldridge, Kimberly R. Houchard, Xiaoxi Zhuang

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Excessive sequential stereotypy of behavioral patterns (sequential super-stereotypy) in Tourette's syndrome and obsessive compulsive disorder (OCD) is thought to involve dysfunction in nigrostriatal dopamine systems. In sequential super-stereotypy, patients become trapped in overly rigid sequential patterns of action, language, or thought. Some instinctive behavioral patterns of animals, such as the syntactic grooming chain pattern of rodents, have sufficiently complex and stereotyped serial structure to detect potential production of overly-rigid sequential patterns. A syntactic grooming chain is a fixed action pattern that serially links up to 25 grooming movements into 4 predictable phases that follow 1 syntactic rule. New …

The Impact Of The Variability Hypothesis On Margaret F. Washburn's And Mary W. Calkins' Parodoxical Relations With Faculty In Their Graduate Programs, Ginger Hudson, Ann N. Elliott

Modern Psychological Studies

This paper offers a possible explanation for the paradoxical relations for two of psychology's 19th century female pioneers with faculty members in their graduate programs: Margaret F Washburn and James M. Cattell at Columbia University; and Mary W. Calkins and Hugo Munsterberg at Harvard University. Cattell's and Munsterberg's strong support and advocacy for these female graduate students appear contradictory to their general beliefs regarding women's intellectual capacities and pursuit of higher education. However, it is suggested that their views were, in fact, consistent with the variability hypothesis, which drew a sharp distinction between "average" and "exceptional" women. It is further …

Age And Cohort Differences In Flashbulb Memory, Jenny Denver

Modern Psychological Studies

Current research in autobiographical memory gives evidence of both a retention effect and a "reminiscence bump," as well as evidence of an agerelated decline in older adults' ability to vividly recall certain memories. The present study investigated the existence of an age-related decline and the reminiscence bump in flashbulb memories, which Brown and Kutik (1977) describe as detailed, vivid, and persistent memories for unexpected, emotional events. Participants from three age groups (n=220) were questioned about three potential flashbulb memory events (9 / 11, JFK's assassination, and Pearl Harbor). Younger adults had lengthier free recall accounts for 9/11 than middle-aged and …

Exploratory Study Of Anger And Behavior In An Incarcerated Offender Population Utilizing The Mahan And Ditomasso Anger Scale, Robert John Marsh, Jr.

PCOM Psychology Dissertations

The present study proposed to advance the treatment and assessment of anger disorders by exploring the properties of the Mahan and DiTomasso Anger Scale (MAD-AS). Previous research of the reliability, validity, and factor structure of the MAD-AS was conducted with inpatient (Mahan, 2001) and outpatient participants (Beardmore, 2003) . In the present study a psychometric investigation was undertaken utilizing 300 male incarcerated offenders. The MAD-AS correlated positively with the presence of antisocial and borderline personality disorders and with violent offenses. Those inmates with a history of violent offenses scored significantly higher than those convicted of nonviolent offenses on the MAD-AS. …

Non-Acute Cognitive Sequelae Associated With Recreational Ecstasy Use: A Meta-Analysis, Tiffany Leigh Linkovich Kyle

Electronic Theses and Dissertations

Studies using animal models have found considerable evidence of neurological damage resulting from exposure to 3,4- methylenedioxymethamphetamine (MDMA, ecstasy). Yet, studies comparing the cognitive performance of human recreational ecstasy users to ecstasy naïve controls have produced inconsistent results. The present study is a meta-analysis of the published empirical literature on the cognitive sequelae of human recreational ecstasy use. The pooled effect size estimate for combined cognitive domains was statistically significant and moderate in size. Small to large, statistically significant aggregate effect sizes resulted for eight of the nine cognitive ability domains included in the analysis. Moderator analyses suggested that frequent …

Empirical Modeling Of A Marijuana Expectancy Memory Network In Children As A Function Of Age And Marijuana Use, Jacqueline Alfonso

Electronic Theses and Dissertations

The present investigation modeled the expectancy memory organization and likely memory activation patterns of marijuana expectancies of children across age and marijuana use. The first phase of the study surveyed 142 children to obtain their first associate to marijuana use. From their responses, the Marijuana Expectancy Inventory for Children and Adolescents (MEICA) was developed. The second phase of the study administered the MEICA to a second sample of 392 children to model marijuana expectancy organization and probable memory activation paths of marijuana users versus never-users. Results indicated that irrespective of age, adolescents who have used marijuana tend to emphasize positive-negative …

Human Mental Models Of Humanoid Robots, Sau-Lai Lee, Ivy Yee-Man Lau, Sara Kiesler, Chi-Yue Chiu

Research Collection School of Social Sciences

Effective communication between a person and a robot may depend on whether there exists a common ground of understanding between the two. In two experiments modelled after human-human studies we examined how people form a mental model of a robot's factual knowledge. Participants estimated the robot's knowledge by extrapolating from their own knowledge and from information about the robot's origin and language. These results suggest that designers of humanoid robots must attend not only to the social cues that robots emit but also to the information people use to create mental models of a robot.

The Effect Of Color On Viewers’ Ratings Of Paintings, Donald J. Polzella, Stephanie H. Hammar, Chad W. Hinkle

Psychology Faculty Publications

Sixty college students rated digitized facsimiles of 20 paintings on 12 semantic differential scales. The paintings represented two classes of content, landscape and portrait, and two styles, traditional and modern. Half the participants viewed the paintings in color, half in black and white. Removing color from portraits increased their perceived pleasantness and beauty and reduced tension. In contrast, removing color from landscapes reduced their perceived beauty. It is argued that for landscapes color may provide a critical channel for transmitting increased amounts of information such as depth. For portraits, color can be superfluous or even distracting.

Efficacy Of Modified Parent Training To Facilitate Expressive Language Of Children With An Expressive Language Delay, Marie Henderson

LSU Master's Theses

This study aimed to study the efficacy of a modified parent-training program on parents’ use of language facilitative techniques. The training method employed a handout and discussion of the facilitative techniques and how they could be incorporated into play time with the children. Participants included 4 parent-child dyads recruited from a school for children with language delays. Effectiveness of the training was determined by taking data on parent and child behaviors from tape recordings of parent-child play interactions that occurred in each family’s home. Results showed that parents were able to use the procedures during baseline and maintained relatively stable …

Horsepower : A Study Of Equine Influence On Female Adolescent Self-Efficacy, Vanessa Gay Hancox

Theses : Honours

Self-efficacy refers to the individual's belief in their capacity to exert control over themselves as well as situations which impact upon them: perceptions of self-efficacy influence cognitive development, behavioural capacity and emotional states. Low self-efficacy is often associated with problematic drug use, inappropriate sexual activity, low academic achievement, anxiety, depression, self-harming and suicidal behaviours during adolescence. Conversely, high self-efficacy is generally correlated with high academic achievement, positive social relationships and formation of sexual identity, increased self-regulatory ability and positive vocation selection. This study sought to examine the experiences of a group of five young women, aged between thirteen and seventeen …

Effects Of 5-Ht2 Receptor Ligands On Tail Pinch-Induced Stress Responding And Open Field Behavior, John K. Hearn

LSU Master's Theses

Stress is known to exert an influence on neuroendocrine, autonomic, hormonal, and immune functioning. As a result of the debilitating effects of stress on numerous bodily systems, there exists a large body of research devoted to the etiology, physiological sequelae, and treatment of the condition. Further, the neurotransmitter serotonin (5-HT) has been implicated in stress responding. Presently, there is conflict in the literature as to the precise role serotonin plays in mediating the stress response. This study was an attempt to further elucidate the role of 5-HT in mediating an organism’s response to tail pinch stress and the open field. …

Effects Of Spaced Retrieval On Memory And Quality Of Life In Older Adults With Probable Alzheimer's Disease, Karri S. Hawley

LSU Doctoral Dissertations

This study was designed to explore the effects of spaced-retrieval training on memory and quality of life in older adults with probable Alzheimer’s disease. A total nineteen older adults with probable Alzheimer’s disease (AD) participated in these experiments. Experiment one was designed to determine whether the spacing effect is contributing to the success of the spaced-retrieval intervention. Participants were trained to recall a name-face association using either the adjusted spaced-retrieval method or a fixed interval retrieval method. The results showed a more consistent performance profile for the spaced retrieval group in comparison to the fixed interval group, providing evidence that …

Serotonin And Stress Responding In Animals: Role Of 5-Ht.2a/C Receptors In The Central And Peripheral Nervous Systems, Sarah Mathews Uzelac

LSU Doctoral Dissertations

Behavioral responses to stressors can be influenced in different ways by both serotonin (5-HT) agonists and antagonists. Further study, of both different stressors as well as different 5-HT agents, is needed to clarify the place of 5-HT in stress responding. To date, no published report has investigated the influence of centrally and/or peripherally administered 5-HT2A/C agonist DOI or the 5-HT2A/C antagonist ketanserin on behaviors evoked by tail pinch or open field stressors. Five separate, related experiments were conducted to investigate this influence. It was hypothesized that that peripherally (Experiment 1), centrally (Experiment 2), and centrally + peripherally (Experiment 3) injected …

Ability Of College Students To Simulate Adhd On Objective Measure Of Attention, Randee Lee Booksh

LSU Doctoral Dissertations

Complaints of ADHD symptoms in college students are not uncommon and college students frequently self-refer for assessment of ADHD. Some may seek out a diagnosis to obtain academic accommodations and/or stimulant medication. Diagnosing ADHD in college students is largely reliant on self-report measures, and to a lesser extent, objective measures of attention. The typical college student has easy access to information about ADHD, potentially facilitating efforts to simulate self-reported symptoms. The present study examined the ability of college students to effectively simulate ADHD on objective and self-report measures of attention, and examined the relationship between knowledge of ADHD and ability …

The Psychosocial Vulnerability Model Of Hostility As A Predictor Of Coronary Heart Disease, Karen Grothe

LSU Doctoral Dissertations

Coronary heart disease (CHD) is the number one killer for both men and women in the United States today. African Americans are particularly at risk, due to higher prevalence rates and mortality related to CHD (American Heart Association, 2003). Less than half of the new cases of CHD can be predicted with known risk factors (tobacco use, obesity, hypertension), which suggests the possible influence of personality or additional behavioral factors. Hostility is a psychological variable that has been consistently related to health outcomes, particularly to CHD. While the exact mechanism linking hostility to health is currently unknown, a psychosocial vulnerability …

Some Effects Of Self-Monitoring, Perceived Norms, And Sex-Role Stereotypes On Romantic Betrayals, Alissa Anne Garth

UNF Graduate Theses and Dissertations

It was hypothesized that high self-monitors (compared to low self-monitors) would report more betrayals of their romantic partners. Perceptions of others' betrayals should follow sex-role stereotypes (i.e., males are more likely to betray than females). Sex-role stereotyping might be attenuated when counter-stereotypical norms are made salient. One-hundred seventy five undergraduates completed the Interpersonal Behavior Survey (Roscoe et aI., 1988) and the Self-Monitoring Scale (Snyder & Gangestad, 1986). Before doing so, participants read one of two instructional sets: females are more likely than males to betray their romantic partners; people in general are likely to betray their romantic partners. Participants responded …

Chimpanzee Use Of Modulation In Response To Questions, Jen-Shiuan (Susan) Shiau

All Master's Theses

Modulation in American Sign Language is meaningful systematic change in sign form. Young cross-fostered chimpanzees used sign modulations in ways that resemble human signers. Jensvold and Gardner (2000) videotaped conversations between adult chimpanzees-Washoe, Moja, Tatu, and Dar-and a human interlocutor under four conditions: general, on-topic, off-topic, and can't. Signs from this dataset were selected and analyzed for modulation. Like human signers, the adult chimpanzees modulated the signing speed, size, length, and number of reiterations. They used both single and combinatorial modulations. Modulation use varied with different functional categories of signs. The chimpanzees varied the sign modulation on repeated glosses between …

Role Of Cognitive Distortions And Dysfunctional Attitudes In Nurses Experiencing Burnout, Cynthia A. Diefenbeck

PCOM Psychology Dissertations

As a means of gathering more data to support the utility of cognitive-behavioral therapy with individuals experiencing burnout, this current study is designed to identify whether or not distorted thinking and dysfunctional attitudes are present in registered nurses who are experiencing burnout and whether or not they differ in registered nurses not experiencing burnout. A mail survey to a random sample of certified critical care registered nurses working in hospital settings was conducted. Participants provided basic demographic data and completed the Maslach Burnout Inventory, the Inventory of Cognitive Distortions, and the Dysfunctional Attitudes Scale. In addition, participants completed measures of …

Validating The Impact Of Event Scale With Adolescents : A Look At The September 11, 2001, Terrorist Attacks, Claudia Lingertat

PCOM Psychology Dissertations

The current study examined the psychometric properties of the Impact of Event Scale (IES; Horowitz, Wilner, & Alvarez, 1979), a self-report measure of current subjective distress. Twenty-four adolescents from an urban high school were surveyed regarding their experiences from the events of September 11, 2001. The IES showed a moderate correlation with the My Worst Experience Scale (MWES; Hyman, Snook, Berna, & Kohr, 1997). Findings indicate the IES may be effective as a quick screening tool for the intrusive and avoidant symptoms of posttraumatic stress in adolescents pending further research with a larger sample.

Assessment Of Anger In Persons With Cognitive Limitations : A Revision Of The Ads-Vii , Wayne David Schmoyer

PCOM Psychology Dissertations

Assessment of angry patients with mental retardation or borderline intellectual functioning is time consuming. Existing assessment tools may be inadequate for gathering data and for guiding treatment, thus presenting a challenge for practitioners. The Anger Disorders Scale (DiGiuseppe & Tafrate, 2001) samples the cognitive, affective, and behavioral components of anger. However, this scale is a self-report survey for adults of average or higher intellectual functioning. This investigation provided a feasibility test of the "Anger Disorders Interview for persons diagnosed with Mental Retardation" (ADIMR), a modified version of the Anger Disorders Scale designed as a clinical interview for cognitively limited patients …

Time Estimation And Hand Preference, Maria Rodriguez

Electronic Theses and Dissertations

This work examines the effect of participants' gender and handedness on the perception of short intervals of time. The time estimation task consisted of an empty production procedure with forty trials at each of four intervals of one, three, seven, and twenty seconds. The four target intervals represent a natural logarithmic progression and a series that bracket important temporal thresholds. The order of presentation of those intervals was randomized across participants but yoked across the sexes in each of the respective dominant hand groups. The two between-subject factors, with two levels each, were sex and handedness. Participants produced forty estimates …

Chorda Tympani Nerve Transection At Different Developmental Ages Produces Differential Effects On Taste Bud Volume And Papillae Morphology In The Rat, Suzanne I. Sollars

Psychology Faculty Publications

Chorda tympani nerve transection (CTX) results in morphological changes to fungiform papillae and associated taste buds. When transection occurs during neonatal development in the rat, the effects on fungiform taste bud and papillae structure are markedly more severe than observed following a comparable surgery in the adult rat. The present study examined the potential “sensitive period” for morphological modifications to tongue epithelium following CTX. Rats received unilateral transection at 65, 30, 25, 20, 15, 10, or 5 days of age. With each descending age at the time of transection, the effects on the structural integrity of fungiform papillae were more …
