Visual Attention, Color Processing And Physiological Measure Differences In Males And Females With Substance Abuse And Opiate Addiction, Jo Ann Petrie Mar 2012

Visual Attention, Color Processing And Physiological Measure Differences In Males And Females With Substance Abuse And Opiate Addiction, Jo Ann Petrie

Theses and Dissertations

A biological marker of the addictive state would be a major breakthrough in objectively assessing the efficacy of treatment outcomes. Given its role in the mesolimbic system and drug reward, most biological marker studies for addiction focus on measures related to dopamine (DA). Dopamine is also implicated in some disorders of visual attention and plays a modulatory role in the processing of color in the retinal DA pathway. For example, visual processing in the retina has been shown to co-vary with DA levels during cocaine withdrawal. In this electroencephalographic (EEG) study, we studied event related potentials (ERPs) and reaction time …

Behavioral And Histological Effects Of Traumatic Brain Injury On Alzheimer's Disease Transgenic Mice, Sara Leilani Kellogg Mar 2012

Behavioral And Histological Effects Of Traumatic Brain Injury On Alzheimer's Disease Transgenic Mice, Sara Leilani Kellogg

USF Tampa Graduate Theses and Dissertations

The main objective of this study was to elucidate the possible mechanistic link between traumatic brain injury (TBI) and Alzheimer's disease (AD) using an animal model. We examined behavioral and histological effects of TBI in pre-symptomatic AD-transgenic mice (C57B6/SJL/SwissWebster/B6D2F1). In previous studies, these mice displayed AD-like behavioral deficits by 15-17 months of age and AD-like neuropathology as early as six months of age. To clarify the effects of TBI on these mice, the present study began when they were about three months of age and the study ended when they were about five months of age. As a control, non-transgenic …

Tool Use In Fishes, Culum Brown Mar 2012

Tool Use In Fishes, Culum Brown

Sentience Collection

Tool use was once considered the sole domain of humans. Over the last 40 years, however, it has become apparent that tool use may be widespread across the animal kingdom. Pioneering studies in primates have shaped the way we think about tool use in animals, but have also lead to a bias both in terms of our expectations about which animals should be capable of using tools and the working definition of tool use. Here I briefly examine tool use in terrestrial animals and consider the constraints of the current working definition of tool use in fishes. Fishes lack grasping …

Mixing Metaphors In The Cerebral Hemispheres: What Happens When Careers Collide?, Selmaan Noah Chettih , '10, Frank H. Durgin, Daniel J. Grodner Mar 2012

Mixing Metaphors In The Cerebral Hemispheres: What Happens When Careers Collide?, Selmaan Noah Chettih , '10, Frank H. Durgin, Daniel J. Grodner

Psychology Faculty Works

Are processes of figurative comparison and figurative categorization different? An experiment combining alternative-sense and matched-sense metaphor priming with a divided visual field assessment technique sought to isolate processes of comparison and categorization in the 2 cerebral hemispheres. For target metaphors presented in the right visual field/left cerebral hemisphere (RVF/LH), only matched-sense primes were facilitative. Literal primes and alternative-sense primes had no effect on comprehension time compared to the unprimed baseline. The effects of matched-sense primes were additive with the rated conventionality of the targets. For target metaphors presented to the left visual field/right cerebral hemisphere (LVF/RH), matched-sense primes were again …

Stress Alters The Discriminative Stimulus And Response Rate Effects Of Cocaine Differentially In Lewis And Fischer Inbred Rats, Therese A. Kosten, Mindy Miserendino Mar 2012

Stress Alters The Discriminative Stimulus And Response Rate Effects Of Cocaine Differentially In Lewis And Fischer Inbred Rats, Therese A. Kosten, Mindy Miserendino

Psychology Faculty Publications

Stress enhances the behavioral effects of cocaine, perhaps via hypothalamic-pituitary-adrenal (HPA) axis activity. Yet, compared to Fischer 344 (F344) rats, Lewis rats have hyporesponsive HPA axis function and more readily acquire cocaine self-administration. We hypothesized that stress would differentially affect cocaine behaviors in these strains. The effects of three stressors on the discriminative stimulus and response rate effects of cocaine were investigated. Rats of both strains were trained to discriminate cocaine (10 mg/kg) from saline using a two-lever, food-reinforced (FR10) procedure. Immediately prior to cumulative dose (1, 3, 10 mg/kg cocaine) test sessions, rats were restrained for 15-min, had 15-min …

Complex Patterns Of Male Alliance Formation In A Dolphin Social Network, Joanna Wiszniewski, Culum Brown, Luciana M. Möller Feb 2012

Complex Patterns Of Male Alliance Formation In A Dolphin Social Network, Joanna Wiszniewski, Culum Brown, Luciana M. Möller

Sentience Collection

The formation and maintenance of alliances is regarded as one of the most socially complex male mating strategies in mammals. The prevalence and complexity of these cooperative relationships, however, varies considerably among species as well as within and between populations living in different ecological and social environments. We assessed patterns of alliance formation for Indo-Pacific bottlenose dolphins, Tursiops aduncus, in Port Stephens, New South Wales, Australia, to investigate the stability of these alliances, the structure of associations, as well as variation in schooling patterns among males. Our results showed that association patterns among males within this population showed considerable variability. …

Topography Of The Chimpanzee Corpus Callosum, Kimberley A. Phillips, William D. Hopkins Feb 2012

Topography Of The Chimpanzee Corpus Callosum, Kimberley A. Phillips, William D. Hopkins

Psychology Faculty Research

The corpus callosum (CC) is the largest commissural white matter tract in mammalian brains, connecting homotopic and heterotopic regions of the cerebral cortex. Knowledge of the distribution of callosal fibers projecting into specific cortical regions has important implications for understanding the evolution of lateralized structures and functions of the cerebral cortex. No comparisons of CC topography in humans and great apes have yet been conducted. We investigated the topography of the CC in 21 chimpanzees using high-resolution magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). Tractography was conducted based on fiber assignment by continuous tracking (FACT) algorithm. We expected …

The Multi-Scale Dynamics Of Executive Function, Jason Anastas Jan 2012

The Multi-Scale Dynamics Of Executive Function, Jason Anastas

Master's Theses

Cognitive control is a central issue in developmental psychology. Traditional theories of psychology solve this problem by positing a top-down central executive, which coordinates cognitive resources in pursuit of goals. We propose an alternative explanation: cognitive control arises from physical interactions across many different timescales within the system. College and preschool aged participants were asked to complete a simple executive function task, card sorting. We found that multi-scale physical interactions differed depending on experimental constraints, and that executive function in these cases was driven primarily by flexibility in multi-scale interactions, rather than the dominance of one scale. This suggests that, …

Differences Between Post-Bariatric Patients And Controls In A Substance Abuse Rehabilitation Program: Implications For Treatment, Ashley A. Wiedemann Jan 2012

Differences Between Post-Bariatric Patients And Controls In A Substance Abuse Rehabilitation Program: Implications For Treatment, Ashley A. Wiedemann

Master's Theses and Doctoral Dissertations

A comprehensive substance abuse treatment facility began observing increased admissions who reported histories of bariatric surgeries. The present study examined what unique variables may pose risk for substance abuse among bariatric surgery candidates and what issues may affect prognosis or treatment outcome for those currently in substance abuse treatment. Participants completed a questionnaire and participated in a semi-structured interview. Results indicate that post-bariatric patients developed problematic substance use significantly later in life, during a time that is not normative of new development of substances; were significantly more likely to be diagnosed with alcohol use disorders; and reported a significantly poorer …

The Effect Of An Enriched Environment And Cognitive Maturity On Long-Term Reactivation Of Object Recognition Memory In Male Sprague-Dawley Rats., Lisette Roman Jan 2012

The Effect Of An Enriched Environment And Cognitive Maturity On Long-Term Reactivation Of Object Recognition Memory In Male Sprague-Dawley Rats., Lisette Roman

Psychology Honors Papers

This study examined the effect of environment and cognitive maturity on longterm reactivation of recognition memory in rats. Forty male Sprague-Dawley rats were housed in either an enriched environment or standard conditions. Animals were tested in the Novel Object Recognition (NOR) task as either adults or periadolescents. Results showed exposure to an enriched environment significantly increased the ability of animals to discriminate between a novel and a familiar object. Results also revealed that the impact of environmental enrichment was significant in adults but not in periadolescents. Immunohistochemical staining for the immediate-early gene products c-Fos and zif268 was performed to examine …

Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried Jan 2012

Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried

Psychology

Episodic memory, which depends critically on the integrity of the medial temporal lobe (MTL), has been described as ‘‘mental time travel’’ in which the rememberer ‘‘jumps back in time.’’ The neural mechanism underlying this ability remains elusive. Mathematical and computational models of performance in episodic memory tasks provide a specific hypothesis regarding the computation that supports such a jump back in time. The models suggest that a representation of temporal context, a representation that changes gradually over macroscopic periods of time, is the cue for episodic recall. According to these models, a jump back in time corresponds to a stimulus …

Parenting As Phenotype: A Behavioral Genetic Approach To Understanding Parenting, Shirley Mcguire, Nancy Segal, S. Hershberger Jan 2012

Parenting As Phenotype: A Behavioral Genetic Approach To Understanding Parenting, Shirley Mcguire, Nancy Segal, S. Hershberger

Psychology

This article discusses the behavioral genetic (BG) approach to parenting. Parenting is considered a phenotype that can be influenced by nature and nurture. Genetic contributions to parenting are conceptualized as evidence of genotype–environment correlation (rGE). Early BG studies focused on demonstrating that some parenting dimensions were heritable due to passive and evocative rGE processes. Current studies are investigating moderators and mediators of genetic and environmental contributions to parenting. The paper uses parent and child report data on parental warmth from the Twins, Adoptees, Peers, and Siblings study to illustrate the BG approach. Results show that heritability is …

Examining Social Anxiety And Depression Among Excessive Online Gamers, Nathan Sharer Jan 2012

Examining Social Anxiety And Depression Among Excessive Online Gamers, Nathan Sharer

Theses, Dissertations and Capstones

The main purpose of this study was to examine the correlations between social anxiety, depression, and other psychological factors among online gamers in order to better understand the differences between excessive gamers (whose habits interfere with relationship, occupational, social, or health issues) and enthusiastic gamers (who spend much of their free time playing games but do not report any significant functional impairment as a result). A literature review revealed diverse conceptualizations of excessive gaming as well as differing opinions of what classifies gaming to be excessive/addicting/problematic, suggesting a need to more specifically analyze gaming habits in terms of coexisting pathology …

West Virginia Therapists' Knowledge Of Tarasoff-Related Court Cases, Bruce E. Clay Jan 2012

West Virginia Therapists' Knowledge Of Tarasoff-Related Court Cases, Bruce E. Clay

Theses, Dissertations and Capstones

The Tarasoff decisions regarding the duties to third parties were profoundly significant to the practice of psychology and counseling. Despite this, there have been few studies regarding the impact on these decisions on clinical practice. There are essentially three sources of data regarding the analysis of any Tarasoff-related clinical scenario. They include state statutes, court case law and the professional ethics codes. Most of the limited studies conducted have indicated serious knowledge gaps with respect to relevant state statues and the essence of the Tarasoff duties. This study evaluated West Virginia therapists’ knowledge of Tarasoff-related court cases. It was hypothesized …

The Impact Of Sleep Quality On Cognitive Functioning In Parkinson's Disease, Karina Stavitsky, Sandra Neargarder, Yelena Bogdanova, Patrick Mcnamara, Alice Cronin-Golomb Jan 2012

The Impact Of Sleep Quality On Cognitive Functioning In Parkinson's Disease, Karina Stavitsky, Sandra Neargarder, Yelena Bogdanova, Patrick Mcnamara, Alice Cronin-Golomb

Psychology Faculty Publications

In healthy individuals and those with insomnia, poor sleep quality is associated with decrements in performance on tests of cognition, especially executive function. Sleep disturbances and cognitive deficits are both prevalent in Parkinson's disease (PD). Sleep problems occur in over 75% of patients, with sleep fragmentation and decreased sleep efficiency being the most common sleep complaints, but their relation to cognition is unknown. We examined the association between sleep quality and cognition in PD. In 35 non-demented individuals with PD and 18 normal control adults (NC), sleep was measured using 24-hr wrist actigraphy over 7 days. Cognitive domains tested included …

Melatonin And Its Effect On Learning And Memory, Nechama Leah Bauman (Cahn) Jan 2012

Melatonin And Its Effect On Learning And Memory, Nechama Leah Bauman (Cahn)

The Science Journal of the Lander College of Arts and Sciences

Melatonin is a neurohormone produced by the pineal gland and secreted into the body in a circadian rhythm. Melatonin is known to be involved in many vital body functions, including sleep, reproduction, and immune response. Exogenous melatonin, sold as over the counter natural supplements in drugstores, is commonly taken by many people to help cure various ailments. Melatonin also plays a role in the hippocampus. This paper investigates the effects of melatonin on long-term potentiation in the hippocampus. Long-term potentiation, described as a long-lasting strengthening of synapses between nerve cells, is thought to be responsible for long-term memory retention. It …

Diminished Conditioned Responding To The Nicotine Stimulus By Antidepressant Drugs With Differing Specificity For The Serotonin And Norepinephrine Transporter, Amanda M. Dion, Scott C. Sanderson, L. Charles Murrin, Rick A. Bevins

Department of Psychology: Faculty Publications

People diagnosed with depression also tend to have a co-morbid nicotine addiction. Thus, there is interest in whether medications used to treat depression alter the effects of nicotine. This study assessed whether the antidepressant drugs citalopram, imipramine, and reboxetine, with differing specificity for the serotonin and norepinephrine transporter, altered responding controlled by the conditional stimulus (CS) effects of nicotine. Rats received intermixed 20-min nicotine (0.4 mg base/kg, SC) and saline sessions. On nicotine sessions, rats had intermittent access to sucrose; no sucrose was available on saline sessions. After discrimination performance stabilized and a nicotine generalization curve (0.025–0.4 mg/kg) was established, …

The Effects Of Distractors In Multiple Object Tracking Are Modulated By The Similarity Of Distractor And Target Features, Cary S. Feria Jan 2012

The Effects Of Distractors In Multiple Object Tracking Are Modulated By The Similarity Of Distractor And Target Features, Cary S. Feria

Faculty Publications

Is the effect of distractors in multiple object tracking dependent on the distractors sharing the features of the targets? In experiment 1, observers tracked five targets among five distractors that were identical to the targets and a number of additional distractors that were either identical to or featurally distinct from the targets. Results showed that distractors that are distinct from the targets in shape or color, or are stationary, impair tracking less than distractors that are identical to the targets. However, tracking performance declined as the number of distractors increased, even for featurally distinct distractors. Experiment 2 showed that distractors …

Expectations Do Not Always Influence Food Liking, Jamie Phillip Hale Jan 2012

Expectations Do Not Always Influence Food Liking, Jamie Phillip Hale

Online Theses and Dissertations

The purpose of the present experiment was to examine how expectations influence cracker ratings on a scale of likeability. A large body of research shows that expectations affect food experiences (Wansink, 2004; Eertmans, Baeyens & Van den Bergh, 2001; Kahkonen & Tuorila, 1998). Participants were not aware that the primary interest of the study was how expectations influence cracker ratings. Participants were assigned to either a positive expectation group or a neutral expectation group. Participants in the positive expectation group received a positive verbal cue indicating that the crackers had recently been rated high in a national taste test. The …

A Quantitative Analysis Of The Reward-Enhancing Effects Of Nicotine Using Reinforcer Demand, Scott T. Barrett, Rick A. Bevins Jan 2012

A Quantitative Analysis Of The Reward-Enhancing Effects Of Nicotine Using Reinforcer Demand, Scott T. Barrett, Rick A. Bevins

Department of Psychology: Faculty Publications

Reward enhancement by nicotine has been suggested as an important phenomenon contributing toward tobacco abuse and dependence. Reinforcement value is a multifaceted construct not fully represented by any single measure of response strength. The present study evaluated the changes in the reinforcement value of a visual stimulus in 16 male Sprague–Dawley rats using the reinforcer demand technique proposed by Hursh and Silberberg. The different parameters of the model have been shown to represent differing facets of reinforcement value, including intensity, perseverance, and sensitivity to changes in response cost. Rats lever-pressed for 1-min presentations of a compound visual stimulus over blocks …

Understanding The Motivational Consequences Of Extreme School Violence Through The Lens Of Mortality Salience: The Case Of Academic Self-Stereotyping In Math, Aaron Wichman Jan 2012

Understanding The Motivational Consequences Of Extreme School Violence Through The Lens Of Mortality Salience: The Case Of Academic Self-Stereotyping In Math, Aaron Wichman

Psychological Sciences Faculty Publications

We conducted an investigation into a determinant of academic motivation that has implications for how we respond to school violence and tragedy. We conducted two studies to examine whether exposure to messages related to the salience of one’s own mortality cause people to align their own academic beliefs more closely with stereotypical beliefs about their social groups. When exposed to graffiti images that contained messages such as R.I.P. (i.e., rest in peace), males and females in Study 1 expressed math attitudes that resembled the American stereotype of male superiority and female inferiority in this domain. In Study 2, writing about …

Attitudes Toward Male Vegetarians: Challenging Gender Norms Through Food Choices, Brooke Browarnik Jan 2012

Attitudes Toward Male Vegetarians: Challenging Gender Norms Through Food Choices, Brooke Browarnik

Psychology Honors Papers

Research suggests that individuals learn to “do gender” and adhere to traditional gender norms from an early age. Those who do not do gender on a daily basis often experience adverse consequences (e.g., ridicule from others). The present study was designed to expand upon the literature regarding perceptions of a particular group of men who do not conform to gender norms – male vegetarians. Participants read one of four brief scenarios about a vegetarian or omnivore, male or female student who is vying for a student government position. After reading the scenario, participants 1) answered a series of questions about …

Confronting Language, Representation, And Belief: A Limited Defense Of Mental Continuity, Kristin Andrews, Ljiljana Radenovic Jan 2012

Confronting Language, Representation, And Belief: A Limited Defense Of Mental Continuity, Kristin Andrews, Ljiljana Radenovic

Sentience Collection

According to the mental continuity claim (MCC), human mental faculties are physical and beneficial to human survival, so they must have evolved gradually from ancestral forms and we should expect to see their precursors across species. Materialism of mind coupled with Darwin’s evolutionary theory leads directly to such claims and even today arguments for animal mental properties are often presented with the MCC as a premise. However, the MCC has been often challenged among contemporary scholars. It is usually argued that only humans use language and that language as such has no precursors in the animal kingdom. Moreover, language is …
