From Nixon’S War On Drugs To Obama’S Drug Policies Today: Presidential Progress In Addressing Racial Injustices And Disparities, Cigdem Sirin

Departmental Papers (PS)

This study investigates presidential progress in addressing racial injustices and disparities within the context of the war on drugs. I argue that racial inequalities emanating from the war on drugs have been largely overlooked and at times aggravated by previous administrations. Although there have been some improvements in this regard since President Obama took office, more extensive policy reforms are needed to better remedy such inequalities. I also argue that the viability of a progressive presidency for racial justice vis-à-vis U.S. drug policies depends not only on the personal agenda of the president but also on a supportive public as …

Examining Experience In Depressed And Nondepressed Individuals, Jedidiah D. Gunter

UNLV Theses, Dissertations, Professional Papers, and Capstones

The inner experience of nine depressed and nine nondepressed individuals was explored using Descriptive Experience Sampling. Each participant completed four days of descriptive experience sampling, exploring about six moments of their inner experience on each sampling day. Although the Depressed participants self-reported substantially higher levels of depressive symptomatology on the Center for Epidemiological Studies Depression scale (CES-D) on each day of sampling, the differences in the frequency of depressive symptomatology in the inner experiences of these two groups were not statistically significant. Despite the group differences not reaching statistical significance, the Depressed group experienced somewhat more frequent moments of depression, …

Perceptions Of Sexual Dangerousness: Accurate Identification Of Sexual Offenders From Static Photographs, Amber Jean Culbertson-Faegre

Graduate Theses and Dissertations

The present research expands understanding of the phenomenon of accurate identification of sexually dangerous men. Study 1 was designed to examine the influence of experience on accuracy of perceptions of sexual dangerousness. Receiving feedback about test trials increased accuracy on future trials at a marginally significant level. Study 2 was designed to determine the importance of specific facial features on these judgments. This study, however, failed to replicate the findings from the first study. Implications for Study 1, as well as possible explanations for Study 2 are discussed.

The Effects Of Caffeine And Expectancy On Short Term Memory, Sara J. O'Brien

Doctoral Dissertations and Master's Theses

Although caffeine is the most widely used drug in the world, research on the effects of caffeine on mental performance tasks (especially short term memory tasks) is inconclusive. One possible explanation for this limited understanding is the lack of studies accounting for participant expectancy surrounding caffeine. This study examined the effects of caffeine dosage (0mg, 200mg, and 400mg) and expectancy related to past caffeine use (positive, negative) on short term memory span task. A two-way Analysis of Variance showed that the two independent variables (caffeine dose and expectancy), did not significantly influence the short term memory span score. However, the …

Picture Recognition Of Food By Macaques (Macaca Silenus), Peter G. Judge

Faculty Journal Articles

Pictorial representations of three-dimensional objects are often used to investigate animal cognitive abilities; however, investigators rarely evaluate whether the animals conceptualize the two-dimensional image as the object it is intended to represent. We tested for picture recognition in lion-tailed macaques by presenting five monkeys with digitized images of familiar foods on a touch screen. Monkeys viewed images of two different foods and learned that they would receive a piece of the one they touched first. After demonstrating that they would reliably select images of their preferred foods on one set of foods, animals were transferred to images of a second …

A Kinder, Gentler Nativism?: Review Of Alison Gopnik, The Philosophical Baby, David Moshman

Department of Educational Psychology: Faculty Publications

Review of Alison Gopnik, The philosophical baby: What children's minds tell us about truth, love, and the meaning of life.

In its historic philosophical and psychological formulations, nativism highlighted innateness. Development was deemed nothingmore than a genetically driven process ofmaturation; learning, in turn, was nothing more than the filling in of superficial content. In this determinist view, neither development nor learning could be deemed active, creative, or constructive processes, and nothing genuinely new could result.

The nativists who have increasingly populated the literature of developmental psychology since the 1980s, however, are neonativists. Neonativists fully accept modern views of immature organisms …

Examining The Effects Of Political Information And Intervention Stages On Public Support For Military Interventions: A Panel Experiment, Cigdem Sirin

Selected Works Temporary Series

This study examines the formation and continuity of public support for military interventions as a function of political information levels and intervention stages using a panel experiment. The results demonstrate that politically informed individuals express less support for a military intervention at the beginning of that intervention compared to uninformed ones. However, as the intervention proceeds and casualties are incurred, the support of politically uninformed people decreases at a higher rate than does the support of the politically informed. As such, politically informed individuals demonstrate more stable levels of support across intervention stages. In addition, success or failure of an …

Lateralization Of Emotion, Reaction Time, And Skin Conductance Responsiveness, Kimberley Erin Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in …

Intact Statistical Word Learning In Autism Spectrum Disorders, Jessica Mayo

Master's Theses

Individuals with Autism Spectrum Disorders (ASD) have impairments in language acquisition, but the underlying mechanism of these deficits is poorly understood. Implicit learning appears potentially relevant to language development, particularly in speech segmentation, which relies on sensitivity to the transitional probabilities between speech sounds. This study aimed to investigate the relationship between implicit learning and current language abilities in school-aged children with autism (n = 17) and typical development (n = 24) using a well-studied artificial language learning task. Results suggest that the ASD and TD groups were equally able to implicitly learn transitional probabilities from a lengthy …

The Effect Of Choice In Exercise Intensity On Affect And Cognition, Annegracien Delaunay

Masters Theses & Specialist Projects

While there are studies linking positive psychological outcomes with exercise, few have focused on choice as a moderating factor. The research that has examined choice as a moderator yielded mixed results. Currently no research has looked at the impact of choice of exercise intensity on the psychological benefits of acute exercise; specifically, affective and cognitive gains. According to Landers (2008), acute exercise refers to a single bout of exercise usually lasting a short duration, whereas chronic exercise refers to long term repeated bouts of exercise (e.g., weeks, months, or years). Participants in this study consisted of 117 collegiate psychology students. …

Examining The Relationship Between Fact Learning And Higher Order Learning Via Retrieval Practice, Pooja Kay Agarwal '01

Doctoral Dissertations

The development of higher order skills is a desired outcome of education. Some believe that higher order learning can be improved directly, whereas others argue that higher order learning can be improved via the enhancement of factual or conceptual knowledge. The relationship between fact and higher order learning is often speculated, but empirically unknown.

This project examines whether retrieval practice via quizzing, a strategy typically used to enhance fact learning, can be used as a strategy to improve higher order skills in both laboratory and applied settings. In the current study, higher order skills were considered to comprise the understand, …

An Electrophysiological Examination Of Adhd-Associated Symptoms And Selective Attention In Adults, Erica Diane Prentkowski

Dissertations

A main component of Attention-Deficit/Hyperactivity Disorder (ADHD) is a deficit of inattention. This deficit causes impairment for both children and adults in a variety of settings including school and work. The current study examined auditory selective attention in a community sample of adults. It was the aim of this project to examine possible differences in selective attention for adults with high levels of ADHDassociated symptoms, when compared to adults with low levels of ADHD-associated symptoms, including conditions under which these differences may be an advantage. Specifically, it was expected that adults with high ADHD-associated symptoms would benefit from the high …

Dubowitz Syndrome: A Review And Implications For Cognitive, Behavioral, And Psychological Features, Rebekah S. Huber, Daniel Houlihan, Kevin J. Filter

Psychology Department Publications

Dubowitz syndrome is a rare autosomal recessive disorder characterized by micorcephaly, short stature, abnormal faces, and mild to severe mental retardation. Growth retardation occurs both intrauterine and postnatal. Behavioral characteristics include hyperactivity, short attention span, and aggressiveness. Behavior problems include difficulty feeding, sleep disturbance, and bedwetting. Individuals with the disorder have displayed shyness, fear of crowds, and dislike of loud noises. A high-pitched or hoarse voice is common. Deficits have been found in speech and language skills, reasoning and memory skills, self-help skills, and psychomotor functioning. Ocular, dental, cutaneous, skeletal, cardiovascular, gastrointestinal, neurological, immunological, and hematological medical difficulties have been …

The Effect Of Endpoint Knowledge On Dot Enumeration, Alex Michael Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study attempts to extend the principle tenets of the Overlapping Waves Theory (Siegler, 1996), a framework designed to explain the progression of trends in cognitive development, to adult participants’ performance in a dot enumeration task. Literature in the 0-100 number line estimation task (Siegler & Booth, 2004, Ashcraft & Moore, 2011) has revealed a pervasive trend in child estimation such that young children (especially those in kindergarten) respond with a logarithmic line of best fit, while children at the third grade and above overwhelmingly respond with linear estimates to this same range of numbers. A similar developmental trend is …

The Effect Of Alcohol On Attention To Social Threat: A Test Of The Avoidance-Coping Cognitive Model, Amy K. Bacon

Graduate Theses and Dissertations

The Avoidance-Coping Cognitive model (Bacon & Ham, 2010) proposed that Socially anxious individuals may be particularly vulnerable to the anxiolytic effects of alcohol through reductions in attention biases to Social threat. Elements of this model and were tested in the present study, in which undergraduate volunteers (N = 41, 27% female) completed two dot probe tasks with photographs of angry, happy, and neutral facial expressions. Participants were randomized to either consume a moderate dose of alcohol (target BAC 0.06%) or a non-alcohol control beverage between the two dot probe tasks. Results indicated no evidence of a bias in attention to …

Imagery And Contamination Aversion, Thomas Grover Adams

Graduate Theses and Dissertations

Contamination-based obsessive-compulsive disorder (OCD) is the most common form of OCD. Recent research indicates that the emotion of disgust may play a primary role in the etiology and maintenance in contamination-based OCD (CB-OCD). However, little is known about the effects of disgust on compulsive behaviors related to CB-OCD (e.g.,, hand-washing). The present study utilized an imagery-priming paradigm to test the effects of experienced disgust on compulsive hand-washing. Seventy-eight participants were selected for high or low symptoms of CB-OCD. Following response training, participants were submitted to a disgust or neutral imagery task. Following the imagery task, participants rated their subjective fear …
