The Effects Of Internal And External Context Reinstatement On Source Memory, Jeffrey Joseph Starns

LSU Master's Theses

Memory for attended aspects of an encoded event (item memory) is facilitated when features of the encoding context are reinstated at test, indicating that item and context features are bound together in memory traces (Smith, 1979). The present study investigated whether reinstated contextual features similarly enhance memory for other contextual details of an event (source memory). Participants studied words that appeared on either the top or bottom of the computer screen in either a large or small font size. Following the study phase, participants completed a recognition/source test in which they had to indicate the location in which they studied …

State-Specific Effects Of Withdrawal In Smokers, Carla J. Rash

LSU Master's Theses

Comparisons of responses to a free-recall task were made in withdrawal and non-withdrawal states of 41 smokers. A 2 x 2 design was used to investigate state-specific learning effects in smokers during nicotine withdrawal using a list of 20 common words. Nicotine withdrawal was defined as a minimum of 12 hours abstinence from smoking. Physiological measures of heart rate and blood pressure were examined for drug-compensatory responses. No significant decreases in physiological responding were found. Additionally, no interaction was found between reported urge and withdrawal. The primary hypothesis regarding state-specific effects on recall was not supported. These findings are to …

On The Conceptual And Linguistic Activity Of Psychologists: The Study Of Behavior From The 1890s To The 1990s And Beyond, David E. Leary

Psychology Faculty Publications

In the early twentieth century psychology became the study of "behavior." This article reviews developments within animal psychology, functional psychology, and American society and culture that help explain how a term rarely used in the first years of the century became not only an accepted scientific concept but even, for many, an allencompassing label for the entire subject matter of the discipline. The subsequent conceptual and linguistic activity of John B. Watson, Edward C. Tolman, Clark L. Hull, and B.F. Skinner, as they attempted to explain "behavior" throughout the course of the twentieth century, is then discussed. Finally, the article …

The Effects Of Aniracetam Treatment On Cognitive Performance And Ampa Receptor Glur2 Subunit Expression After Moderate Fluid Percussion Injury In Rats, Anna Igorevna Baranova

Theses and Dissertations

In addition to the acute pathology produced by traumatic brain injury, there are chronic alterations that occur after the trauma, including a depressed state of neuronal activity (Feeney, 1991). This study included a preclinical testing of a novel treatment strategy focusing on increasing neuronal activity during the chronic hypofunctional posttraumatic stage. The present investigation tested the effects of repeated post-injury aniracetam administration on cognitive performance in the Morris water maze (MWM) and on the GluR2 - immunoreactivity and protein expression by Western blot analysis in the hippocampus. The first study examined the optimal dose of aniracetam in the MWM task. …

The Social Network And Attachment Bases Of Loneliness, David M. Ouellette

Theses and Dissertations

This thesis tests Robert S. Weiss's 1973 theory of loneliness, which claims two types of loneliness: emotional and social. Emotional loneliness is the affective reaction to the absence of a close attachment bond. Social loneliness stems from inadequate integration into a social network. Undergraduate residents of a university dormitory completed questionnaires on loneliness, attachment, personality, and relationships with other dorm residents. Patterns of relational ties among participants were evaluated using social network analysis, specifically density, tie strength, and four forms of centrality. Results reveal that, while controlling for neuroticism, the network measure of outdegree and the two attachment dimensions accounted …

Exploring Women's Experiences Of A Medically Necessary Caesarean, Michelle Cotterell

Theses : Honours

Caesarean delivery accounts for approximately one in four births both in Australia and on a global level. Examination of the experience of caesarean delivery is limited, although as caesarean delivery rates are increasing, a practical understanding of the constructs surrounding surgical birth needs to be gained. This review aims to present an overview of the current literature exploring the mother's experience of caesarean delivery. The different modes of medically necessary caesarean delivery, both unplanned and planned are defined. Societal views of caesarean birth as an easier and convenient mode of delivery in comparison to vaginal birth are described and it …

Psychological And Neuropsychological Correlates Of Postconcussional Disorder, Joy Helena Wymer

LSU Doctoral Dissertations

Chronic symptoms of Postconcussional Disorder (PCD) occur in a significant minority of mild brain injury patients. The latest research suggests an interactionistic perspective as the most logical and empirically supported pathogenesis for the development and maintenance of PCD. The interactionistic perspective implicates organic factors in the development of acute symptoms of PCD, and psychological factors in the maintenance of chronic symptoms. Possible psychological factors relevant in the maintenance of PCD symptoms include a grief response, a coping hypothesis, and the development of dysfunctional coping loops. Providing support for a psychological etiology of symptom maintenance is research indicating reduction of chronic …

The Effects Of Auditory Distraction On Attention Performance In Asymptomatic College Students With A History Of Mild Head Injury, John H.,Ii Denning

LSU Doctoral Dissertations

Introduction: The majority of individuals experiencing a mild head injury (MHI) recover fully experiencing few residual symptoms. Some individuals who fully recover have shown evidence of residual, albeit subtle, brain functioning disturbances on tasks requiring high levels of cognitive effort. Also, memory complaints in MHI patients may be related to these subtle difficulties when cognitive resources are overwhelmed. This study assessed a group of asymptomatic college students with a history of MHI to determine if there were any residual attention difficulties as well as increased memory complaints. Method: One-hundred twelve college students with and without a history of MHI were …

The Diagnosis Of Dementia In Persons With Mental Retardation: Validating Methods Of Assessment, Joanne Bielecki

LSU Doctoral Dissertations

The usual assessment instruments for the diagnosis of dementia are often difficult to use among individuals with mental retardation. This study investigates whether a modified method based on Visser et al. (1997) can identify a dementing process. Ninety individuals diagnosed with severe and profound mental retardation were studied. One half of the participants were diagnosed with Down's syndrome. The participants were equally assigned to one of three groups based on perceived risk of dementia. A differential prevalence design was used. Both cross sectional and longitudinal analyses were utilized in this study. Results indicate that the Visser et al. (1997) method …

Reconfiguring Childhood Boys And Girls Growing Up Global, Cindi Katz

Publications and Research

Children are a spur, a commitment, a way of imaging the future—but all too often these sorts of phrases just rattle around a vacuum, their utterance the beginning and end of the commitment. We emphasize “the best interests of the child,”but this gloss provides a moral imperative to all manner of uncompleted projects and unfulfilled policies. Likewise, the use of children’s images or presence in public forums of all types gives a patina of honorableness to practices and plans that never actually make good on the promissory note of childhood. The 1992 Rio Earth Summit is a notable example. Such …

The Role Of Dopamine In Motivational And Receptive Aspects Of Female Mouse Sexual Behavior, Amber Bradshaw Hodges

Dissertations, Theses, and Capstone Projects

A pacing paradigm investigated the modulatory role of monoamines in the mesolimbic dopamine system on copulatory behavior in female mice. Specifically whether there is a distinction between the neural regulatory mechanisms of pacing behavior and receptive behavior was determined. Pacing measures motivational and rewarding components of copulation by the female's contacts and withdrawals from the male, while receptivity is the willingness to engage in copulations and is measured by the number of sexual stimulations received. A pacing paradigm was established and female mice were observed to pace in a similar manner, but at a lesser rate, than female rats.

Dopamine …

Estrogen And Hippocampal Synaptic Plasticity, Michael R. Foy, Michael Baudry, Richard Thompson

Psychological Science Faculty Works

During the past several years, there has been increasing interest in the effects of estrogen on neural function. This enthusiasm is driven, in part, by the results of early clinical studies suggesting that estrogen therapy given after menopause may prevent, or at least delay, the onset of Alzheimer's disease in older women. However, later clinical trials of women with probable Alzheimer's disease had contrary results. Much of the current research related to estrogen and brain function is focused in two directions. One involves clinical studies that examine the potential of estrogen in protecting against cognitive decline during normal aging and …

The Selfish Nature Of Generosity: Harassment And Food Sharing In Primates, Jeffrey R. Stevens

Jeffrey Stevens Publications

Animals may share food to gain immediate or delayed fitness benefits. Previous studies of sharing have concentrated on delayed benefits such as reciprocity, trade and punishment. This study tests an alternative model (the harassment or sharing–under–pressure hypothesis) in which a food owner immediately benefits because sharing avoids costly harassment from a beggar. I present an experiment that varies the potential ability of the beggar to harass, and of the owner to defend the food, to examine the effects of harassment on food sharing in two primate species: chimpanzees (Pan troglodytes) and squirrel monkeys (Saimiri boliviensis). For …

Perception Of Empty And Filled Time Intervals In Pigeons: An Attentional Allocation Explanation Of The Empty Interval Illusion, Stephanie Hornyak

Theses and Dissertations (Comprehensive)

Studies with humans and non-human animals have established how stimulus properties play an important role in the subjective duration of time. A phenomenon referred to as the Filled Interval Illusion has been found with humans, which demonstrates that filled intervals are perceived to be longer than empty intervals of equivalent duration. Recently, it has been demonstrated that pigeons judge empty time intervals bounded by two 500-ms light markers to be longer than an equivalent filled interval of light. Experiment 1 was able to replicate the Empty Interval Illusion with pigeons. Experiment 2 attempted to determine whether the Empty Interval Illusion …

Visual Expectations: Using Machine Learning To Identify Patterns In Psychological Data, Skyler Place

Honors Theses

The goal of this project was to utilize the tools of machine learning to evaluate the data obtained through experiments in psychology. Advanced pattern finding algorithms are an effective approach to analyzing large sets of data, from any domain of science. Consequently, we have a psychological question and hypothesis, and a separate machine learning technique to assess these claims. The realm of psychology that I focused on is visual cognition, and how an individual's knowledge affects how they see the world. This alteration of visual data is a part of perception -when the brain enhances the data coming in from …

The Effects Of Family Functioning And Parent Structure On The Prevalence And Intensity Of Childhood Fears, Rebecca Leis Pederson

Masters Theses

The current study was designed to examine the relation between family factors, such as family functioning and parent structure, and the prevalence and intensity of childhood fears. One hundred and sixteen children in grades 3-12 were surveyed using the Fear Survey Schedule-II. Of the 116 children surveyed, 75 had parents who returned the Self Report Family Inventory and demographic survey. Results indicated that younger, female participants reported fears of greater prevalence and intensity than male participants. Contrary to predictions, neither family functioning or any of its associated factors were found to be related to the prevalence and intensity of childhood …

Transforming Learning Into A Constructive Cognitive And Metacognitive, Haydee Cuevas

Electronic Theses and Dissertations

This study explored the effectiveness of embedding a guided, learner-generated instructional strategy (query method), designed to support learners' cognitive and metacognitive processes, within the context of a computer-based complex task training environment (i.e., principles of flight in the aviation domain). The queries were presented as "stop and think" exercises in an open-ended question format that asked learners to generate either simple (low-level elaboration) or complex (high-level elaboration) sentences from a list of key training concepts. Results consistently highlighted the benefit of presenting participants with low-level elaboration queries, as compared to the no-query or high-level elaboration queries. In terms of post-training …

Olanzapine Attenuates Cue-Elicited Craving For Tobacco, Kent E. Hutchinson, Marie-Christine Rutter Goodworth, Raymond Niaura, Robert Swift, Wallace B. Pickworth, Laura Sobik

Faculty Publications - Doctor of Psychology (PsyD) Program

Rationale: Recent biological conceptualizations of craving and addiction have implicated mesolimbic dopamine activity as a central feature of the process of addiction. Imaging, and pharmacological studies have supported a role for dopaminergic structures in cue-elicited craving for tobacco.

Objective: If mesolimbic dopamine activity is associated with cue-elicited craving for tobacco, a dopamine antagonist should attenuate cueelicited craving for tobacco. Thus, the aim of the present study was to determine whether an atypical antipsychotic (olanzapine, 5 mg) decreased cue-elicited craving for tobacco.

Method: Participants were randomly assigned to 5 days of pretreatment with olanzapine (5 mg; n=31) or were randomly assigned …

Two 1/2-Year-Old Children Use Animacy And Syntax To Learn A New Noun, Jane B. Childers, C. H. Echols

Psychology Faculty Research

We examine how attention to animacy information may contribute to children's developing knowledge of language. This research extends beyond prior research in that children were shown dynamic events with novel entities, and were asked not only to comprehend sentences but to use sentence structure to infer the meaning of a new word. In a 4 × 3 design, animacy status (e.g., animate agent, inanimate patient) and labeling syntax (agent, patient, nonlabel control) were varied. Across most events, 21/2-year-old participants responded as if they expected animate entities to be named. However, in a prototypical (animate agent-inanimate patient) event condition, children responded …

Behavioral Theory Of Timing Applied To A Drl-Limited Hold Procedure, Jill Skarvan '04

Honors Projects

The behavioral theory of timing (Killeen & Fetterman, 1988) holds that animals use behavioral tasks, called adjunctive behaviors, to aid them in timing intervals. Several studies have supported this theory, however the majority of these studies have been correlational. The present study used an experimental approach to manipulate the presence of adjunctive behavior. Rats responded on two DRL limited-hold procedures in which subjects must wait a certain time interval before responding; early responses were not reinforced and reset the clock. In addition, the animal had a specific interval of time in which to make a response; late responses were not …

Electroconvulsive Therapy : An Assessment Of Experience, Knowledge, And Attitudes Of Clinical Psychologists In Western Australia, Dawn A. Barrett

Theses: Doctorates and Masters

Introduced to modern psychiatry in 1938, electroconvulsive therapy (ECT) is the application of an electrical current to the brain, administered under a general anaesthetic and with the use of muscle relaxants. The procedure is primarily used for psychiatric disorders and remains a controversial intervention. Issues of contention centre on claims of efficacy, safety and the validity of “informed” consent. Prominent side effects include memory loss with psychological sequelae reported to include fear, grief and loss. Previous studies of mental health professionals report experience of working in a ECT environment increases knowledge and promotes a positive attitude. Very few studies have …

A Softer Side To Men, Michael J. Lenney

Theses: Doctorates and Masters

“I am on time. It’s the afternoon of my medical for life-insurance suitability. The AMP building in Sydney is my destination. I arrive with about twenty minutes to spare. I don’t remember the receptionist. I don’t remember the faces of the doctors who attended me that day. All I can remember is that I could see the clouds passing over the glass ceiling as my blood pressure was taken several times. The first doctor took my blood pressure three times before seeking another opinion. The second doctor confirmed his fears. I was in the “too high” risk category. At the …

Determining Criminal Motive Using Deductive Profiling: A Feasibility Study, Kelly J. Dupont

Dissertations and Theses @ UNI

In recent years criminal profiling has gained increasing popularity and attention as a result of media and law enforcement interest. It is becoming increasingly apparent that the field is lacking in essential empirical support. The FBI's Crime Classification Manual, used to train FBI profilers, states in its opening pages that the information provided in the manual is not empirically derived; rather it is based on the collective opinion of those with experience in law enforcement (Douglas, Burgess, & Burgess, 1992). An area particularly in need of research is the relationship between motive and criminal behavior. Understanding motive can be a …

Becoming A Sister: The Socialization Of Women Into A Sorority, Kathleen Hughes

Masters Theses & Specialist Projects

Adult peer groups have become more and more a topic for sociological study. It is a phenomenon that is starting to gain interest. This research focuses on one sorority on the campus of a Midwestern university and how this sorority manages to incorporate the women that they pledge through formal recruitment into the sorority and how these women fully socialize themselves into this group of women who already have bonded with each other. A synthesis of symbolic interactionism and social exchange theory helps to break down the socialization process and shows how the new members move through the stages of …

Environmental Enrichment And Prior Experience Of Live Prey Improve Foraging Behaviour In Hatchery-Reared Atlantic Salmon, C. Brown, T. Davidson, K. Laland

Aquaculture Collection

Atlantic salmon salmo salar L. parr were reared for 3 months under standard hatchery conditions or in a structurally enriched tank (containing plants, rocks and novel objects). Half of each of these fish had prior exposure to live prey in the form of live bloodworm while the other half were fed hatchery-pellets. After 12 days all fish were tested on a novel live prey item (brine shrimp). A significant interaction between the two factors (prior exposure to live prey and rearing condition) revealed that foraging performance was only enhanced in fish that had been reared in a complex environment and …

Response Cost In The Treatment Of Lunging In Dogs, Jennifer L. Sobie

Masters Theses

Contemporary professional applied animal behavior management employs a diagnostic and treatment approach for unwanted pet behavior that incorporates ethology-based causal factors. As in behavior therapy for humans, behavioral assessment includes descriptive functional analysis when possible to determine relevant contingency variables. But this information is then considered in the context of an appropriate motivational classification, such as social or prey-directed motivation or fear-motivated, and treatments are designed accordingly. A different view is that behavior can be treated effectively without a presumption of the motivation through analysis of the manifestation of the behavior itself. This study sought to evaluate the efficacy of …

The Situation: An Introduction To The Situational Character, Critical Realism, Power Economics, And Deep Capture, Jon Hanson, David Yosifon

Faculty Publications

Throughout most of this introductory Article, we will focus our arguments primarily on economics and law and economics. We believe, however, that the implications of our inquiry extend far beyond those domains. The tendencies we hope to elucidate find their origins in the human animal, not in any particular legal theoretic perspective. It happens that these tendencies are especially prominent in law and economics, currently the dominant theoretical paradigm for creating and analyzing legal policy. But the relevance of our thesis is not confined to one approach , or even to legal-political questions. All humans are more or less implicated, …

Novel Object Test: Examining Nociception And Fear In The Rainbow Trout, Lynne U. Sneddon, Victoria A. Braithwaite, Michael J. Gentle

Veterinary Science and Medicine Collection

This study aimed to assess fear responses to a novel object while experiencing a noxious event to determine whether nociception or fear will dominate attention in a fish in novel object testing paradigm. This experimentally tractable animal model was used to investigate (1) the degree of neophobia to a novel object while experiencing noxious stimulation, (2) the response of the fish after removing the fear-causing event by using a familiar object, and (3) the effects of removing the nociceptive response by morphine administration and examining the response to a novel object. Control animals displayed a classic fear response to the …

Age Group Differences In Recall Of Relevant And Irrelevant Words, Daniel Jose' Padilla

Master's Theses - Daytona Beach

Many studies have shown that older adults tend to perform more poorly on memory tasks, when compared to younger people. Conversely, studies have also indicated that there may be ways to combat this decline in age related memory performance by using memory aid techniques. In addition to memory aid techniques, word familiarity may be used to increase memory performance because working memory for familiar words benefits from the availability of long-term phonological memory representations, which act to "clean up" the decaying memory traces of items in the list retrieval stage. This memory study compared word recall performance of younger and …
