Deadly Paradox Of Self-Defense, Rodger E. Broome Phd

Rodger E. Broome

Police deadly force is not intended to kill, but its purpose is to stop a violent person from hurting others. It is a desperate measure to bring someone physically under control, even at the risk of taking his or her life. In my research, the officers’ lived experience with shooting another person was paradoxical. Each shot fired by the officers was the most horrible thing they had ever done while being vital to surviving the encounters. Every bullet that hit its mark improved the likelihood that the officer would live while each bullet extinguished the life of the adversary. The …

Perceptual Fluency Can Be Used As A Cue For Categorization Decisions., Sarah J Miles, John Paul Minda

Brain and Mind Institute Researchers' Publications

Learning in the prototype distortion task is thought to involve perceptual learning in which category members experience an enhanced visual response (Ashby & Maddox. Annual Review of Psychology, 56, 149-178, 2005). This response likely leads to more-efficient processing, which in turn may result in a feeling of perceptual fluency for category members. We examined the perceptual-fluency hypothesis by manipulating fluency independently from category membership. We predicted that when perceptual fluency was induced using subliminal priming, this fluency would be misattributed to category membership and would affect categorization decisions. In a prototype distortion task, the participants were more likely to judge …

Affect Identification And Interpersonal Skills: An In-Depth Evaluation Of Social Cognition In Schizophrenia, Griffin Pollock Sutton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The presence of deficits in various sub-domains of social cognition has been investigated to a degree in individuals with schizophrenia. Some of the most commonly researched and documented deficits have included impairments in the identification of affect portrayed in faces. Research has indicated that the performance of individuals with schizophrenia on such tasks is generally impaired as compared to normal controls. However, some have questioned the generalizability of such findings to real-world situations, as day-to-day interactions generally necessitate a constant, fluid assessment of the thoughts and feelings of others and are rarely, if ever, limited to still images of others. …

Construct And Criterion Validity Of The Rey Auditory Verbal Learning Test-Spanish Version In Adults With Traumatic Brain Injury, Cristobal Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Rey Auditory Verbal Learning Test (RAVLT) is among the most commonly used English-language neuropsychological tests of verbal learning and memory. Previous research supports the validity and clinical utility of adaptations of the RAVLT into many diverse languages. In the United States, Hispanics represent the largest and fastest-growing ethnic minority group. As the Hispanic populace continues to grow, so does the need for empirically validated Spanish-language neuropsychological measures. In 2002, a Spanish adaptation of the RAVLT was developed in Puerto Rico (Acevedo-Vargas, 2002). However, validation studies have not been undertaken with clinical samples, and little is known regarding its psychometric …

Hippocampal Theta And Gamma: Effects Of Aging, Environmental Change, Cholinergic Activation And Learning, Matthew D. Howe

Honors Scholar Theses

During aging, hippocampal functioning is impaired; specifically aged humans and rats show reduced performance on spatial memory tasks. An age-related reduction in the neurotransmitter acetylcholine has been postulated to underlie this impairment. Rhythmic oscillations (theta, gamma) may serve to synchronize activity within the hippocampus and across the brain during learning; these may also change with aging.

To determine what aspects of oscillation are important for memory processing, the effects of aging, encountering a novel situation, learning a new task and cholinergic system activation (with physostigmine) were examined. Both age groups showed increased theta, but not gamma activity when encoding a …

Interactive Effects Of Working Memory Self-Regulatory Ability And Relevance Instructions On Text Processing, Nancy Jo Hamilton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reading is a process that requires the enactment of many cognitive processes. Each of these processes uses a certain amount of working memory resources, which are severely constrained by biology. More efficiency in the function of working memory may mediate the biological limits of same. Reading relevancy instructions may be one such method to assist readers in utilizing working memory resources more efficiently.

This study examines the relationship between perspective relevance instructions and participants' ability to regulate their working memory resources. In a 3 x 2 x 2 design the study extended the literature by utilizing a measure of fluid …

The Seditious Class, Donelson R. Forsyth

Jepson School of Leadership Studies articles, book chapters and other publications

I never saw it coming. My students and I had just shared a splendid semester-long educational experience. I had deftly mixed original readings, engaging class discussions, illuminating lectures, and thoughtful assessments with a community-based project that gave students the opportunity to apply course concepts in a real-world setting. Or had I? You would think that, after some 30 years of opening packets of students’ evaluations at the semester’s end (and now, downloading them from the University’s evil evaluation website), that the thrill would be gone—no more disappointment, elation, or surprise.

Not so.

My course was a required one, populated with …

Predator-Based Fear Conditioning: A Novel Approach To The Study Of The Neurobiology Of Memory, Joshua D. Halonen

USF Tampa Graduate Theses and Dissertations

This series of experiments developed novel paradigms involving the integration of conventional and ethologically relevant forms of reinforcement in the study of fear conditioning in rats. Experiment 1 compared the effects of foot shock, immobilization and predator exposure, alone and in combination, on the expression of conditioned fear memory and extinction. The combination of all 3 reinforcers produced a significantly stronger fear memory and greater resistance to extinction, compared to when each reinforcer was administered alone. Furthermore, whereas conditioning with foot shock, alone, resulted in rapid extinction of the fear memory, the combination of immobilization and cat exposure, or all …

The Effect Of Spiritualism On The Cognitive Functions On Learning And Memory, Carla Antonieta Farcello

McNair Poster Presentations

Last summer I conducted a pilot study which researched whether better working memory would be documented among an experimental group (individuals who report being spiritual) as compared to the control group (individuals who report being non-spiritual).Total scores showed a significantly higher sense of spiritualism among the spiritual participants vs. the non spiritual participants (p < .001) along with a significant improvement in working memory for spiritual participants vs. non spiritual participants (p = .027). The results of this study documented significantly better performance on a task measuring emotional learning and memory among individuals who reported being spiritual as opposed to individuals who reported being non-spiritual. These findings build on prior studies suggesting the effect of positive emotions on broadening cognitive processes (Strauss & Allen, 2003).

My current study is building on what my prior findings have suggested and studies the effect of spiritualism on the cognitive functions of learning and memory. In addition to the Daily Spiritual Experiences Scale (DSES) used in the pilot study, I am including the Spirituality Index …

Children Use Different Cues To Guide Noun And Verb Extensions, Jane B. Childers, M. Elaine Heard, Kolette Ring, Anushka Pai, Julie Sallquist

Psychology Faculty Research

Learning new words involves decoding both how a word fits the current situation and how it could be used in new situations. Three studies explore how two types of cues— sentence structure and the availability of multiple instances-- affect children’s extensions of nouns and verbs. In each study, 2½-year-olds heard nouns, verbs or no new word while seeing the experimenter use a novel object to perform an action; at test, they were asked to extend the word. In Study 1, children hearing nouns in simple sentences used object shape as the basis for extension even though, during the learning phase, …

Chronic Orofacial Pain Influences Self-Regulation In A Rodent Model, Tracey Christine Kniffin

Theses and Dissertations--Psychology

Self-regulation is the capacity to exert control over cognition, emotion, behavior, and physiology. Since chronic pain interferes with the ability to self-regulate, the primary goal of this study was to examine, in rodents, the effects of chronic pain on self-regulation processes. Sixteen male Sprague-Dawley rats were divided into two groups: (1) chronic constriction injury of the infraorbital nerve (CCI-ION) and (2) naïve. Testing confirmed that CCI-ION animals had significant mechanical allodynia compared to naïve animals (p<0.001). A two-part self-regulation behavioral paradigm consisting of a cued go/no-go task and a subsequent persistence task was developed based on human paradigms. In the cued task, both groups made fewer incorrect lever presses in post-surgery trials (p<0.001); naive animals had a greater decrease in number of incorrect presses than CCI-ION animals (p=0.06). Similarly, both groups had a larger correct to total lever presses ratio in post-surgery trials (p<0.001); naïve animals had a greater increase than CCI-ION animals (p=0.06). In the persistence task, naïve animals experienced a greater decrease in lever presses (p=0.08) than did CCI-ION animals (p=0.66). These results suggest that animals experiencing chronic pain were not able to learn as well as naïve animals, and may have difficulty responding to novel environmental demands.

Explicit Learning In Down Syndrome: A Cross-Sectional Developmental Trajectory Approach, B. Allyson Phillips

Books and Monographs

The purpose of the current study was to analyze the cross-sectional developmental trajectories of explicit category learning in individuals with Down syndrome compared to individuals with intellectual disability and typically developing individuals. Explicit learning is active, conscious, controlled, and intentional; it is a deliberate attempt to acquire new knowledge or skill from repeated tries with feedback. Explicit learning improves with age throughout childhood and is closely related to intelligence. Because of its relation to intelligence, we expected individuals with Down syndrome to perform below the level expected for their chronological age and nonverbal ability.

The sample was comprised of 41 …

How Psychotherapy Trainees Experience Theoretical Orientation Development : A Phenomenological Study, Mark Mason

Legacy Theses & Dissertations (2009 - 2024)

Knowledge and application of theory are integral to the practice of psychotherapy. Despite the focus on theory in clinical training, little is known about how psychotherapy trainees experience, learn about, and develop a theoretical orientation. This phenomenological study used grounded theory methods to examine 15 counseling and clinical psychology doctoral students' experiences developing a theoretical orientation. The specific purpose of the study was to understand in depth these trainees' perspectives on and attributions about learning and developing expertise with a specific theoretical orientation.

Investigating Insight As Sudden Learning, Ivan K. Ash, Benjamin D. Jee, Jennifer Wiley

Psychology Faculty Publications

Gestalt psychologists proposed two distinct learning mechanisms. Associative learning occurs gradually through the repeated co-occurrence of external stimuli or memories. Insight learning occurs suddenly when people discover new relationships within their prior knowledge as a result of reasoning or problem solving processes that re-organize or restructure that knowledge. While there has been a considerable amount of research on the type of problem solving processes described by the Gestalt psychologists, less has focused on the learning that results from these processes. This paper begins with a historical review of the Gestalt theory of insight learning. Next, the core assumptions of Gestalt …

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 …

Training Evaluation In Virtual Worlds: Development Of A Model, Richard N. Landers, Rachel C. Callan

Psychology Faculty Publications

Many organizations have adopted virtual worlds (VWs) as a setting for training programs; however, research on appropriate evaluation of training in this new setting is incomplete. In this article, we address this gap by first exploring the unique issues relevant to evaluation faced by training designers working in VWs. At the macro-organizational level, the primary issue faced is an organizational culture unreceptive to or otherwise skeptical of VWs. At the micro-organizational level, two major issues are identified: individual trainees unreceptive to VWs and general lack of experience navigating VWs. All three of these challenges and their interrelationships may lead to …
