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

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.

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 …

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 …

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 …

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 …

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 …

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 …

Relationships Between Religious Orientation And Academic Attitudes, Lauren Everitt

Psychology Theses & Dissertations

The goal of this study was to examine whether there is an underlying consistency between college students' approaches to religion and their approaches to higher education. A sample of 234 undergraduate students completed the Religious Life Inventory (Batson, Schoenrade, & Ventis, 1993), which assesses orientation to religion, and the Academic Attitude Scale (Wong, 1998), which identifies factors that motivate students to pursue higher education. The three dimensions (Means, End, and Quest) extracted from the Religious Life Inventory were compared to the six subscales (Intrinsic, Instrumental, Personal Development, External Pressure, Social Interest, No Better Option) of the Academic Attitude Scale to …

Essential Oils Peppermint And Rosemary Exposed To The Olfactory Sense And The Effects On Cognition And Perceived Mood, Tara A. Ricciardelli

Undergraduate Theses and Capstone Projects

Recent research suggests that essential oils of a certain quality can enhance memory consolidation and cognitive performance. The present study examined whether the essential oils rosemary and peppermint were powerful enough to significantly improve short-term memory in recall and recognition tasks. Participants were in a room with a device that diffused a scent or water (no scent) for ten minutes prior to their entry. The participants viewed word lists and were later tested for accuracy in terms of recall and recognition. Results from a one-way analyses of variance demonstrated that peppermint and rosemary did not significantly improve short-term memory or …

Effect Of Anchoring On Perceived Amniocentesis Related Miscarriage Risk Within A Latina Population, Laura E. Panos

Dissertations & Theses (Open Access)

Most recognized pregnancies are completed without difficulty, yet there is always a 3-5% background risk to have a child with a birth defect. Amniocentesis, the most common type of prenatal diagnostic test, is used to detect chromosomal abnormalities, such as Down syndrome. Amniocentesis is associated with a risk of complications that can lead to a miscarriage, which is typically quoted to be between 1 in 300 and 1 in 500. Amniocentesis uptake rates are typically lowest within the Latina community, and although the factors related to this have been studied before, no specific conclusions have been reached.

Knowledge And Perception Of The Role Of Targeted Ultrasound In Detecting Down Syndrome Among A High Risk Population, Ashley M. Henriksen

Dissertations & Theses (Open Access)

The purpose of this study was to determine the perception and knowledge of targeted ultrasound in women who screen positive for Down syndrome in the first or second trimester, and to assess the perceived detection rate of Down syndrome by targeted ultrasound in this population. While several studies have reported patient perceptions’ of routine ultrasound, no study has specifically examined knowledge regarding the targeted ultrasound and its role in detecting Down syndrome. A targeted ultrasound is a special ultrasound during the second trimester offered to women who may be at a higher-than-average risk of having a baby with some type …

When The Therapist Is Homosexual: An Examination Of Therapeutic Outcome Satisfaction, Lewis G. Busbee

Graduate Theses

This study investigated the relationship between client satisfaction and therapist sexuality. The current literature had little or no research on the topic. This article defines psychotherapy, noted that most clients perceived psychotherapy was beneficial, and found research stating therapists should consider all ethical implications when working with clients, particularly in regard to how influential therapist can be on their clients. A questionnaire packet was given to participants, and they were asked to complete: a demographic page, and a vignette that included gender and sexuality of therapist, along with a hypothetical treatment plan, a modified version of the CSQ-8 (Attkisson,1977/2011) which …

A Funny Thing About Marriage, Genevia R. Slate

Graduate Theses

The purpose of the present study was to examine the relationship between marital satisfaction and the use of humor, and to investigate whether or not this relationship was influenced by the length of marriage. I also examined how humor was appreciated as the couples were married longer and who produced the most humor; the husband or the wife. It was hypothesized that marital satisfaction would be highest among married couples who use higher levels of humor, that couples who had been married longer would have a greater appreciation of humor, and that the male partner would produce the most humor …

Physician Perceptions Of Risk Regarding Mood Disorders And Pharmacological Management During Pregnancy: What Is Current Practice?, Laura G. Hendon

Dissertations & Theses (Open Access)

Mood disorders are the most common form of mental illness and one of the leading causes of morbidity worldwide. Major depressive disorder and bipolar disorder have a lifetime prevalence of 16.2% and 4.4%, respectively. Women comprise a substantial proportion of this population, and an estimated 500,000 pregnancies each year involve women with a psychiatric condition. Management with psychotropic medications is considered standard of care for most patients with mood disorders. However, many of these medications are known human teratogens. Because pregnant women with mood disorders face a high risk of relapse if unmanaged, the obstetrician faces a unique challenge in …

Executive Function Profiles In Pediatric Traumatic Brain Injury, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traumatic brain injury is a common cause of disability and death among children in the United States. Insult to the frontal and temporal lobes are frequent in closed head brain injury. Cognitive deficits in a variety of domains are common sequelae of brain trauma. In many cases, trauma to the frontal and temporal lobe regions engender prominent deficits in higher-order cognitive processing, memory, and attention.

Higher-order cognitive processing, or Executive Functions are the grouping of cognitive processes necessary for organization of thoughts and activities, attending to the activities, prioritizing tasks, managing time efficiently, and making decisions (Alvarez & Emory, 2006; …

Bilingualism And Math Cognition, Michelle M. Guillaume

UNLV Theses, Dissertations, Professional Papers, and Capstones

Within cognitive psychology, the fields of bilingualism and math cognition have been investigated relatively separately from one another. Although there has been a substantial amount of research conducted in both areas, few studies have examined mathematical processes as they relate to bilinguals. A couple of the traditional effects found in the math cognition literature, the problem size and associative confusion effects, have been studied with bilinguals; however, bilingual categorization was not carefully controlled for in those studies. There have also been mathematical models applied to bilingual samples; one such model is the encoding-complex model, which has been extended to Chinese-English …

Cognitive Load Of Critical Thinking Strategies, Hanem Shehab

UNLV Theses, Dissertations, Professional Papers, and Capstones

Critical thinking is important for today's life, where individuals daily face unlimited amounts of information, complex problems, and rapid technological and social changes. Therefore, critical thinking should be the focus of general education and educators' efforts (Angeli & Valanides, 2009; Oliver & Utermohlen, 1995). Despite passively agreeing or disagreeing with a line of reasoning, critical thinkers use analytical skills to comprehend and evaluate its merits, considering strengths and weaknesses. Critical thinkers also analyze arguments, recognizing the essentiality of asking for reasons and considering alternative views and developing their own point of view (Paul, 1990). Kuhn and Udell (2007) emphasize that …

Adaptive Memory And Social Influences, Aaron D. Leedy

UNF Graduate Theses and Dissertations

Recently, cognitive psychologists have focused their research on the survival aspects of human memory, showing advantages for remembering information encoded for adaptive qualities. When participants rated words related to survival relevance (stranded in grasslands), Nairne et al. (2007) and others found survival processing’s retention superior to many semantic encoding techniques, however, we questioned the global application of survival processing. In the present adaptive memory experiment we used the thematic word list paradigm pioneered by Deese, Rodeiger and McDermott, allowing us to measure false recall of critical items from sets of word lists. To investigate recall differences based on the material …

Digit Ratios, Baron-Cohen's Reading The Minds In The Eyes And Dart-Throwing Task, Betul Zora

Honors Program Theses

There is evidence that high prenatal testosterone and the ratio of the index finger to the ring finger are correlated. There is also evidence that male-typical finger ratios correlate positively with male-typical tasks such as targeting and negatively correlated with female-typical tasks. This study examines the correlation between the digit ratio and the dart throwing task and also the digit ratio and Baron-Cohen’s Reading the Mind in the Eyes test. A different digit ratio, the ratio of the index finger and the ring finger to the pinky is also collected and correlated with both of the other tests. Sometime during …

Evaluating The Effects Of A Job-Aid For Teaching Visual Inspection Skills To University Students, Candice M. Jostad

Dissertations

Visual inspection is the primary method of data analysis used in behavior analysis. Thus, it is important that behavior analysts have the skills necessary for accurate visual inspection. Research has shown that visual inspection can sometimes be unreliable, which has broad implications for the evaluation of treatment effects using this method. Traditional lectures have been shown to be ineffective in teaching visual inspection skills to a satisfactory level, although improvements in visual inspection have been accomplished using statistical methods and aids such as celeration lines superimposed on graphs. However, these methods are not effective when the aids are removed and …

Assessing The Effects Of A Rectangular Rapid-Flashing Beacon On Vehicle Speeds Along A Four-Lane Divided Highway, Michelle Van Wagner

Dissertations

In 2008, nearly 31% of vehicle fatalities were related to failure to adhere to safe vehicle speeds (National Highway Traffic Safety Administration (NHTSA), 2009). Two studies were conducted to evaluate the effects of a Rectangular Rapid-Flashing Beacon (RRFB) triggered by excessive speed on vehicle speed using a combined alternating treatments and reversal design. Experiment 1 assessed the RRFB's impact on speeds as compared to baseline conditions only. Experiment 2 compared the RRFB to two standard beacon configurations. Both experiments were conducted at the same site during approximately the same time period and both employed the same data collection methodology. The …

Express Yourself: The Effects Of Body Position On Non-Verbal Communication Of Emotions, Kathryn H. Mgrublian

CMC Senior Theses

Recent research has documented that we tend to use the face to express some emotions, but use the body to express other emotions. To understand the contributions of the body to non-verbal emotional communication, we compared the performance of able-bodied participants who were allowed to express emotions naturally (standing) to able-bodied participants who were confined to a wheelchair. Theories of embodied emotion would predict that restraining the use of the body should change emotion production and communication confidence, especially for body-related emotions. Participants expressed six different emotions in three conditions: 1) naturally, 2) face only, and 3) body only. After …

Performance Under Pressure: The Effect Of Explanatory Style On Sensory-Motor Performance Under Stereotype Threat, William R. Macphail

CMC Senior Theses

Do participants with external attribution styles outperform participants with internal explanatory styles in pressure-filled situations? Explicit-monitoring theory suggests that performance becomes impaired when conscious attention is devoted to performing a task normally carried out by automatic processes. Attributing potential failure to an external source (e.g., blaming a sudden gust of wind for a poor golf shot) can decrease the negative effects of stereotype threat, a social-psychological predicament known to engender feelings of stress similar to those experienced in pressure-filled situations, by preventing explicit monitoring from taking place. The current study examined whether individual differences in attribution style, as measured by …

The Relationship Of Leadership Styles, Context, And Outcomes, Max A. Anawalt

CMC Senior Theses

New and experienced leaders sometimes underestimate the importance of the follower and context in their ability to be effective and successful in the long term. During an organization crisis or in a conflict situation, a leaders’ verbal and nonverbal communication behaviors and an awareness of the contextual factors and followers’ feelings involved may contribute more to long-term effectiveness and success more generally than certain characteristics or type of leadership, even if that style is the prevalent model of leadership within the organization. In theory, every leader should benefit from a greater understanding of the evolving study and theory of leadership …

A Theory Of Mental Credit, Jason Soll

CMC Senior Theses

Many philosophical subjects attempt to analyze the basis of human welfare. Theories of desert, distribution of property, and happiness tend to dominate philosophical discourse. Mental credit, which is the mental acquisition of credit for one’s accomplishments and the satisfaction one derives from this credit, is absent from this discourse despite its underlying role in the way people think about their lives. Mental credit is an eternal cognitive good that deserves thoughtful attention and pious decisions for implementation. The following theory of mental credit seeks to serve as a unifying theory for the mental calculations that guide life’s most imperative decisions, …
