The Electrophysiological And Neuropsychological Organization Of Long Term Memory, Richard J. Addante Dec 2011

The Electrophysiological And Neuropsychological Organization Of Long Term Memory, Richard J. Addante

Psychology Faculty Publications

The electrophysiological correlates of recognition memory retrieval were examined in order to identify the neural conditions that precede accurate memory retrieval, characterize the processes that contribute to high and low confidence memory responses, and determine which memory processes are impaired after brain injury. Human electroencephalogram (EEG) was recorded during recognition confidence and source memory judgments in three experiments. In Experiment 1, mid-frontal pre-stimulus theta oscillations were found to precede the stimulus presentation of items that were successfully recollected, but they were not found to be predictive of item familiarity. Moreover, during stimulus presentation, recollection was associated with an increase in …


Change Detection Memory In Rhesus Monkeys And Humans, Lauren C. Elmore Dec 2011

Change Detection Memory In Rhesus Monkeys And Humans, Lauren C. Elmore

Dissertations & Theses (Open Access)

Visual short-term memory (VSTM) is the storage of visual information over a brief time period (usually a few seconds or less). Over the past decade, the most popular task for studying VSTM in humans has been the change detection task. In this task, subjects must remember several visual items per trial in order to identify a change following a brief delay interval. Results from change detection tasks have shown that VSTM is limited; humans are only able to accurately hold a few visual items in mind over a brief delay. However, there has been much debate in regard to the …


Hospitality Students Perceptions About High Risk Behaviors In Relation To Destructive Behaviors And Decision Making, Boris A. Roslov Dec 2011

Hospitality Students Perceptions About High Risk Behaviors In Relation To Destructive Behaviors And Decision Making, Boris A. Roslov

Graduate Theses and Dissertations

This study investigated hospitality students' perceptions regarding alcohol consumption and personal actions related to high risk behaviors. Those behaviors included: sexual encounters and binge drinking, and their effect on academic tasks and performance. The study investigated whether the hospitality student who is employed full time consumes alcohol at a higher level than a hospitality student does that is not employed full time.


Associative And Error-Driven Learning In Younger And Older Adults, Candice B. T. Groves Dec 2011

Associative And Error-Driven Learning In Younger And Older Adults, Candice B. T. Groves

Masters Theses & Specialist Projects

Previous research has consistently shown associative deficits in older adults learning and memory (Chalfonte & Johnson 1996; Naveh-Benjamin, 2000; Naveh-Benjamin, Hussain, & Bar-On 2003) that are related to decreases in hippocampal function (Driscoll et al., 2003; Mitchell, Johnson, Raye, & D’Esposito, 2000). However, older adults learn certain simple predictive relationships between events (Mutter & Williams, 2004) that involve basal ganglia dependent error-driven learning. The goal of the current study was to determine whether error-driven learning could reduce the age-related associative deficits that are associated with hippocampal decline. The results did not support the idea that error-driven learning enhanced older adults’ …


Pain Tolerance And Thresholds In Women With Dyspareunia: Do Pain And Sex Primes Have Differential Effects?, Lea Thaler Dec 2011

Pain Tolerance And Thresholds In Women With Dyspareunia: Do Pain And Sex Primes Have Differential Effects?, Lea Thaler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dyspareunia, defined as recurrent pain in the genital/pelvic region during sexual intercourse, is one of the most common types of female sexual dysfunction, affecting approximately 15% of women between the ages of 18 and 24. Women with dyspareunia display similar cognitive and emotional styles evidenced in other chronic pain conditions (e.g. hypervigilance for pain information, catastrophization, and negative affect); however, dyspareunia is a unique pain disorder in that it directly involves sexual functioning. This pairing of pain and sex raises the issue of conditioning. Is it possible that because intercourse is painful for women with dyspareunia, the presentation of any …


Visual Attention To Erotic Stimuli In Androphilic Male-To-Female Transsexuals, Sarah A. Akhter Dec 2011

Visual Attention To Erotic Stimuli In Androphilic Male-To-Female Transsexuals, Sarah A. Akhter

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study investigated sex differences in visual attention to erotic stimuli by comparing three groups of individuals: heterosexual men, heterosexual women, and androphilic MtF transsexuals. Twenty men, 20 women and 13 MtF transsexuals were shown 10 split-screen slides, each featuring one nude erotic photo of a man shown on half of the screen and one nude erotic photo of a woman shown on the other half of the screen. Eye movements were tracked as participants viewed the slides. All participants were heterosexual (Kinsey 0-1) relative to gender identity, thus erotic targets for natal men were nude women in the …


From Nixon’S War On Drugs To Obama’S Drug Policies Today: Presidential Progress In Addressing Racial Injustices And Disparities, Cigdem V. Sirin Nov 2011

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

Cigdem V. Sirin

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 …

Inspiring Change: The Roles Of Women And Their Communities, Singapore Management University Sep 2011

Inspiring Change: The Roles Of Women And Their Communities, Singapore Management University

Perspectives@SMU

'Change' is a word often employed (and frequently abused) by politicians, industrialists, artists and leaders of various domains as a rallying call. Its effects can be profound on those discontented with the status quo and perhaps uninviting for those already contented with the way things are.


Embodied Cultural Cognition: Situating The Study Of Embodied Cognition In Socio-Cultural Contexts, Angela K. Y. Leung, Lin Qiu, Lay See Ong, Kim-Pong Tam Sep 2011

Embodied Cultural Cognition: Situating The Study Of Embodied Cognition In Socio-Cultural Contexts, Angela K. Y. Leung, Lin Qiu, Lay See Ong, Kim-Pong Tam

Research Collection School of Social Sciences

Embodiment research has demonstrated that cognition is grounded in bodily interactions with the environment and that abstract concepts are tied to the body’s sensory and motor systems. Building upon this embodiment perspective and advancing our understanding, we discuss the extension of embodied cultural cognition. We propose that some associations between bodily experiences and abstract concepts are not randomly formed; rather, the development of such associations is situated in a socio-cultural context, informed by cultural imperatives, values, and habits. We draw evidence supporting this view of embodied cultural cognition in body–mind linkages manifested in construal of emotions, time perception, person perception, …


Person Perception, Bruce D. Bartholow, Cheryl L. Dickter Sep 2011

Person Perception, Bruce D. Bartholow, Cheryl L. Dickter

Arts & Sciences Book Chapters

The complexities of the brain and nervous system make neuroscience an inherently interdisciplinary pursuit, one that comprises disparate basic, clinical, and applied disciplines. Behavioral neuroscientists approach the brain and nervous system as instruments of sensation and response; cognitive neuroscientists view the same systems as a solitary computer with a focus on representations and processes. The Oxford Handbook of Social Neuroscience marks the emergence of a third broad perspective in this field. Social neuroscience emphasizes the functions that emerge through the coaction and interaction of conspecifics, the neural mechanisms that underlie these functions, and the commonality and differences across social species …


Lateralization Of Emotion, Reaction Time, And Skin Conductance Responsiveness, Kimberley Erin Rose Sep 2011

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 …


Examining The Effects Of Political Information And Intervention Stages On Public Support For Military Interventions: A Panel Experiment, Cigdem V. Sirin Aug 2011

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

Cigdem V. Sirin

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 …


Thinking Like Thinkers: Is The Art And Discipline Of An "Attitude Of Suspended Conclusion" Lost On Lawyers?, Donald J. Kochan Aug 2011

Thinking Like Thinkers: Is The Art And Discipline Of An "Attitude Of Suspended Conclusion" Lost On Lawyers?, Donald J. Kochan

Donald J. Kochan

In his 1910 book, How We Think, John Dewey proclaimed that “the most important factor in the training of good mental habits consists in acquainting the attitude of suspended conclusion. . .” This Article explores that insight and describes its meaning and significance in the enterprise of thinking generally and its importance in law school education specifically. It posits that the law would be best served if lawyers think like thinkers and adopt an attitude of suspended conclusion in their problem solving affairs. Only when conclusion is suspended is there space for the exploration of the subject at hand. The …


Living Large: The Powerful Overestimate Their Own Height, Michelle M. Duguid, Jack A. Goncalo Aug 2011

Living Large: The Powerful Overestimate Their Own Height, Michelle M. Duguid, Jack A. Goncalo

Jack Goncalo

Three experiments tested the prediction that individuals’ experience of power influences perceptions of their own height. Power decreased judgments of an object’s height relative to the self (Study 1), made participants overestimate their own height (Study 2) and caused participants to choose a taller avatar to represent them in a second-life game (Study 3). These results emerged regardless of whether power was experientially primed (Study 1 and 3) or manipulated through roles (Study 2). Although a great deal of research has shown that physically imposing individuals are more likely to acquire power, this work is the first to show that …


An Investigation Of Masked Priming Mechanisms In Binary Classification Tasks, Jason Perry Aug 2011

An Investigation Of Masked Priming Mechanisms In Binary Classification Tasks, Jason Perry

Electronic Thesis and Dissertation Repository

The goal of the present research was to examine the nature of masked priming with an emphasis on the influence of stimulus-response (S-R) associations. In Chapter 2, both the magnitude of the category congruence (priming) effect and the nature of the priming distance effect were assessed in two number classification tasks. Participants made either magnitude (i.e., is the target larger or smaller than ‘5’?) or identification judgments (i.e., press one button if the target is a ‘1’, ‘2’, ‘3’ or ‘4’ or the other button if the target is a ‘6’, ‘7’, ‘8’ or ‘9’). Priming distance effects in …


An Electrophysiological Examination Of Adhd-Associated Symptoms And Selective Attention In Adults, Erica Diane Prentkowski Aug 2011

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 …


Anxiety Sensitivity, Non-Acceptance, And Coping Motives For Alcohol Use, Jennifer Ann Shaver Aug 2011

Anxiety Sensitivity, Non-Acceptance, And Coping Motives For Alcohol Use, Jennifer Ann Shaver

Graduate Theses and Dissertations

The present study probed the concurrent relation of two theoretically associated risk factors for coping-motivated substance use - non-acceptance of negative affect and anxiety sensitivity - with coping-motivated drinking frequency (drinking to cope). A two-factor model of coping-motivated substance use put forth by Brown, Lejuez, Kahler, Strong, and Zvolensky (2005) suggests that both non-acceptance and the physical and Social dimensions of anxiety sensitivity might be related to coping motives for substance use broadly. The present study represents a particularly stringent test of this model in the field of alcohol use motives. It was hypothesized that the individual facets of AS …


Aging And Selective Attention In Causal Learning, Melanie Waldrop Asriel Aug 2011

Aging And Selective Attention In Causal Learning, Melanie Waldrop Asriel

Masters Theses & Specialist Projects

This study investigated age differences in generalization of causal value employing similarity as a cue to causality. Exemplars from six food categories (A+, B-, C+, D-. E+, F-) were presented to both young and older adults in two contiguous training phases. Training Phase 1 included exemplars from categories A+, B-, C+, D-. Training Phase 2 included exemplars from A+, B-, E+, F-. Foods in the “+” categories were paired with an outcome of sickness and foods in the “-” categories were not paired with sickness. Tests of causal judgment and exemplar recognition were conducted. For causal judgment, individual exemplars experienced …


Cognitive Processes For Infering Tonic, Steven J. Kaup Aug 2011

Cognitive Processes For Infering Tonic, Steven J. Kaup

Glenn Korff School of Music: Dissertations, Theses, and Student Creative Work, and Performance

Research concerning cognitive processes for tonic inference is diverse involving approaches from several different perspectives. Outwardly, the ability to infer tonic seems fundamentally simple; yet it cannot be attributed to any single cognitive process, but is multi-faceted, engaging complex elements of the brain. This study will examine past research concerning tonic inference in light of current findings. First I will survey the recent history of experimental research in cognitive functions for memory retention and expectation as they relate to the recognition and learning of musical schemas. Then I will discuss distributional theories associated with the tonal hierarchy of major and …


Stereoscopic Vision's Impact On Spatial Ability Testing, George Takahashi Jul 2011

Stereoscopic Vision's Impact On Spatial Ability Testing, George Takahashi

Purdue Polytechnic Masters Theses

A look into spatial ability testing tools and the variations that past researchers made to focus on key factors that affect test scores, will demonstrate the need for tuning traditional testing methods to accommodate a wider demographic and provide more accurate results. Due to technological limitations of the time, a large variety of past spatial tests were developed by hand-drawings. Within this research, the addition of stereoscopic vision is analyzed to determine the value of said changes on human perception of spatial entities.
