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. …

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 …

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, …

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 …

Bridging The Gaps : An Attempt To Integrate Three Major Cognitive Depression Models., Patrick Pössel, Kerstin Knopf

Faculty and Staff Scholarship

There are obvious similarities between the cognitive constructs of Beck’s cognitive theory, the hopelessness model, and the response styles theory. No single comprehensive model has yet integrated the core cognitive concepts of these theories, however. In order to develop such an integrative cognitive model, we conducted two independent studies with 588 and 606 participants, respectively, from a university population. Both studies support the idea that all cognitive constructs of the three models are distinct from each other. Furthermore, both studies provide evidence for the possibility an integration of the constructs in one cognitive model. If future studies replicate these findings, …

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 …

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 …

Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske

USF Tampa Graduate Theses and Dissertations

The contextual cueing effect was initially thought to be the product of memory guiding attention to the target location. However, the steep search slopes obtained in contextual cueing indicate an absence of attentional guidance. We hypothesized that crowding could be obscuring the presence of attentional guidance and investigated this possibility in 2 experiments. Crowding was manipulated by varying the density of items in the local target region in a contextual cueing task. We observed a significant reduction in search slopes between the novel and repeated conditions when crowding was reduced. Enhancing crowding eliminated the contextual cueing effect. These findings suggest …

The Effects Of Eye Gaze Based Control On Operator Performance In Monitoring Multiple Displays, Allison Popola

Doctoral Dissertations and Master's Theses

This study investigated the utility and efficacy of using eye tracking technology as a method for selecting control of a camera within a multiple display configuration. A task analysis with a Keystroke-Level-Model (KLM) was conducted to acquire an estimated time for switching between cameras. KLM estimates suggest that response times are faster using an eye tracker than manual control -indicating a time savings. To confirm these estimates, and test other hypotheses a 2 × 2 within-subjects factorial design was used to examine the effects of Control (Using an eye tracker, or manual) under different Task Loads (Low, High). Dependent variables …

Where Does The Buck Stop? Applying Attribution Theory To Examine Public Appraisals Of The President, Cigdem Sirin, José Villalobos

Selected Works Temporary Series

This study applies attribution theory to examine public appraisals of the president. To date, most political science research on attribution theory has focused on domestic policy and no work has considered both domestic and foreign policy domains in tandem. To fill this gap, we formulate and experimentally test a series of hypotheses regarding the level of responsibility and credit/blame that individuals attribute to the president in both policy domains across varying policy conditions. We also consider how party compatibility affects people’s attribution judgments. Our findings provide a new contribution to the literature on political attributions, executive accountability, and public perceptions …

An Extension Of Sic Predictions To The Wiener Coactive Model, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

The survivor interaction contrasts (SIC) is a powerful measure for distinguishing among candidate models of human information processing. One class of models to which SIC analysis can apply are the coactive, or channel summation, models of human information processing. In general, parametric forms of coactive models assume that responses are made based on the first passage time across a fixed threshold of a sum of stochastic processes. Previous work has shown that the SIC for a coactive model based on the sum of Poisson processes has a distinctive down--up--down form, with an early negative region that is smaller than the …

What Do You Expect? : An Investigation Of How Caffeine Expectancies Affect College Students' Cognitive Performances, Katie Alyse Berg

Undergraduate Honors Thesis Collection

Caffeine use is common, but few studies have examined how the expectancies that people hold about caffeine relate to the effects they experience after consuming it. My study examined how typical caffeine consumption and students' expectancies about how caffeine generally affects them influence their decisions about caffeine use as well as their performance on memory and attention tests. I hypothesized that expectations about how caffeine affects students would interact with their beliefs about how much caffeine they had consumed to impact performance on tests of attention and memory. Undergraduate students were divided into four groups: high consumption and high expectancy, …

Positive Affect During Goal Adoption : Why Happiness Breeds Success, Katherine Wainwright

Undergraduate Honors Thesis Collection

Prior research has shown that positive affect helps individuals to achieve their goals. typically by energizing individuals' performance during goal pursuit. However, questions remain as to whether other mechanisms might exist by which positive affect could facilitate success. Specifically, researchers have yet to address the role that positive affect might play during the process of goal adoption. In the current study, I examined whether positive affect experienced at the time of goal adoption facilitates goal achievement. Participants were induced into either a positive or neutral affective state by watching a video clip. They were also asked to adopt the goal …

The Effects Of A Brief Mindfulness Intervention On Impulsivity In College Students, Myles Elgin Trapp

Undergraduate Honors Thesis Collection

This study investigated the impact of a brief, introductory mindfulness intervention on attention, executive control, and impulsivity. I randomly assigned forty-seven undergraduate students to a treatment group (TG) receiving mindfulness training and a waiting list control group (WLG). Participants completed a battery of self-report questionnaires and standardized neuropsychological tests before and after the intervention. Participants high in trait mindfulness suffered less interference on a Stroop task, were less impulsive on the Balloon Analogue Risk Task, but also evidenced less cognitive flexibility on a dual fluency test at baseline. The TG demonstrated greater improvement than the WLG from baseline to re-test …

Language-Specific Tuning Of Audiovisual Integration In Early Development, Juliana Flynn

Honors Scholar Theses

According to the perceptual narrowing hypothesis, older infants look longer towards speech in a native language than towards a non-native language. We presented speech in English, Spanish, and mis-matched English and Spanish speech, and recorded looking-time towards the speech. Results suggest that the synchrony of speech plays a strong role in infants' attention to speech, whereas nativeness of language does not.

Is It Cohesion Or Diversion? Domestic Instability And The Use Of Force In International Crises, Cigdem Sirin

Selected Works Temporary Series

This study asserts that cohesionary—rather than diversionary—motives primarily influence the propensity of political leaders to use external force in international crises in times of domestic turmoil. Specifically, I contend that mass violence leads political leaders to engage in cohesionary tactics to achieve and maintain social order in their country for political survival. Employing random effects probit analyses with International Crisis Behavior (ICB) data for one-hundred and thirty-nine countries from 1918 to 2005, I find that increased mass violence is more likely than other forms of domestic problems (be it an economic downturn or government instability) to instigate the external use …

Scarcity-Induced Domestic Conflict: Examining The Interactive Effects Of Environmental Scarcity And ‘Ethnic’ Population Pressures, Cigdem Sirin

Selected Works Temporary Series

This study argues that environmental scarcity is more likely to result in civil conflict in countries that experience ‘ethnic’ population pressures (i.e. where the size of the largest minority group is close to parity with the majority group). I refer to this argument as the ‘parity-threat’ approach to the study of scarcity-induced domestic conflict. I empirically test my argument by analysing time-series cross-section data for the period 1979–2000 using four alternative environmental indicators: (1) ecological footprint, (2) biocapacity, (3) scarcity of ecological reserves and (4) water scarcity. The results demonstrate that environmental scarcity increases the probability of civil conflict when …
