Age Differences In Reward Anticipation And Memory, Kristen L. Cushman

Masters Theses & Specialist Projects

Aging research on item- and associative-recognition memory has demonstrated that older adults are deficient in forming associations between two unrelated stimuli. Although older adult performance on tests of item-recognition is similar to younger adult performance, older adults perform worse than younger adults on tests of associative memory (Naveh-Benjamin, Hussain, Guez, & Bar-On, 2003). In addition to the idea that younger adult performance on associative-recognition tests is superior to that of older adults, research has shown that reward cues can enhance motivated learning and item memory performance of younger adults. In an fMRI study that examined the influence of reward anticipation …

The Relationship Between Eating Disorder Symptomology, Critical Body Comments, And Memory Recall, Morgan Littrell

Masters Theses & Specialist Projects

Previous research done in the area of eating disorders suggests many different variables, such as cognitive, biological, and social, that are thought to influence eating disorder development and maintenance. The present study attempts to combine cognitive and sociocultural research findings, memory recall and critical body comments, in an effort to see how, if at all, these two variables affect eating disorder symptomology. Participants for this study were 120 female students that were recruited via Study Board. Participants completed the demographics form, the Eating Disorder Inventory-3 RF, and the Social Hassles Questionnaire. The participants then watched an E-prime presentation of different …

The purpose of the DriveSharp™ training program is to help an individual improve his or her visual attention and useful field of view. Each exercise continually adapts to the individual’s performance so that the training is always at an appropriate level for that specific person. Thirty-two healthy older adult participants were randomly assigned to either the active intervention group (DriveSharp™) or a waitlist control group. Participants in the intervention group were required to engage …

Teleological Reasoning In Adults: Believing In The Purpose Of Events, Carrie Jeanette Guggenmos

Masters Theses & Specialist Projects

Teleological reasoning reflects the general tendency to view objects, behaviors and events in terms of their “purpose.” Although healthy educated adults tend to refrain from committing errors in teleological reasoning about objects, our knowledge regarding how adults reason about events is limited. It has been suggested that teleological reasoning biases our interpretations of emotionally significant and unexpected life events of which a physical or social cause is absent or unsatisfactory. The current investigation seeks to better understand the types of events that evoke a teleological perspective and the conditions and individual difference factors that facilitate it. The results revealed that …

A Hybrid Brain-Computer Interface Based On Motor Intention And Visual Working Memory, Ching-Chang Kuo

Doctoral Dissertations

Non-invasive electroencephalography (EEG) based brain-computer interface (BCI) is able to provide alternative means for people with disabilities to communicate with and control over external assistive devices. A hybrid BCI is designed and developed for following two types of system (control and monitor).

Our first goal is to create a signal decoding strategy that allows people with limited motor control to have more command over potential prosthetic devices. Eight healthy subjects were recruited to perform visual cues directed reaching tasks. Eye and motion artifacts were identified and removed to ensure that the subjects' visual fixation to the target locations would have …

Asymmetry In Resting Alpha Activity: Effects Of Handedness, Ruth E. Propper, Jenna Pierce, Mark W. Geisler, Stephen D. Christman, Nathan Bellorado

Department of Psychology Faculty Scholarship and Creative Works

Frontal electroencephalographic (EEG) alpha band power during rest shows increased right, and/or decreased left, hemisphere activity under conditions of state or trait withdrawal-associated effect. Non-right-handers (NRH) are more likely to have mental illnesses and dispositions that involve such withdrawal-related effect. The aim of the study was to examine whether NRH might be characterized by increased right, relative to left, hemisphere activity during rest. Methods: The present research investigated that hypothesis by examining resting EEG alpha power in consistently-right-handed (CRH) and NRH individuals. Results: In support of the hypothesis, NRH demonstrated decreased right hemisphere alpha power, and therefore increased right hemisphere …

Randomized Clinical Trial Of Cognitive Behavioral Therapy (Cbt) Versus Acceptance And Commitment Therapy (Act) For Mixed Anxiety Disorders, Joanna Arch, Georg Eifert, Carolyn Davies, Jennifer C. Plumb Vilardaga, Raphael D. Rose, Michael G. Craske

Psychology Faculty Articles and Research

Objective—Randomized comparisons of acceptance-based treatments with traditional cognitive behavioral therapy (CBT) for anxiety disorders are lacking. To address this research gap, we compared acceptance and commitment therapy (ACT) to CBT for heterogeneous anxiety disorders.

Method—One hundred twenty eight individuals (52% female, mean age = 38, 33% minority) with one or more DSM-IV anxiety disorders began treatment following randomization to 12 sessions of CBT or ACT; both treatments included behavioral exposure. Assessments at pre-treatment, post-treatment, 6-month, and 12-month follow-up measured anxiety specific (principal disorder Clinical Severity Ratings [CSR], Anxiety Sensitivity Index, Penn State Worry Questionnaire, Fear Questionnaire avoidance) and …

The Impact Of Distractor Duration On Spatial Working Memory In Early Childhood, Brian Keiser

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Spatial attention appears to act as a rehearsal mechanism in spatial working memory (Awh, 1999; Awh & Jonides, 2001) as adults have trouble maintaining spatial information in their mind when required to shift their attention to locations unrelated to the to-be-retained location. Futhermore, adults increase intentional directed attention to the to-be remembered location when warned ahead of time that distractors will be present during the memory delay (Awh, 2003). Our initial study looked at the presence of a distractor and its impacts on spatial working memory in children. We found that the distractor did impact three and six year old …

Frequency-Specificity And Pattern-Specificity Of The Buildup Of Auditory Stream Segregation, David Michael Weintraub

UNLV Theses, Dissertations, Professional Papers, and Capstones

During repeating sequences of low (A) and high (B) tones in an "...ABAB..." pattern, the likelihood of hearing two separate streams ("streaming") increases with more repetitions of the patterns, a phenomenon referred to as "buildup". Previous studies have shown that buildup is frequency specific (Anstis & Saida, 1985) and that its biasing effects decays over several seconds (Beauvois & Meddis, 1997). No study has examined whether the frequency specificity of buildup persists for such a long duration. To address these issues, Experiment 1 tested the decay of frequency-specific and non-frequency specific buildup. The results revealed that (1) frequency-specific buildup effects …

Effects Of Oxygen Deprivation On Pilot Performance And Cognitive Processing Skills: A Pilot Study, David Francis Shideler

Doctoral Dissertations and Master's Theses

According to Federal Aviation Administration (FAA) regulations, pilots flying above 14,000 ft. are required to use supplemental oxygen. The purpose of this study was to examine how oxygen deprivation below 14,000 ft. affects pilot performance using the Frasca Mentor Advanced Aviation Training Device (AATD), and cognitive processing skills using the Automated Neuropsychological Assessment Metrics (ANAM(TM)) cognitive test. The study was conducted in a Normobaric High Altitude Laboratory at simulated altitudes of 5,000 ft. and 14,000 ft. In this pilot study, only five participants were tested; non-significant results of the analysis were anticipated; however, as oxygen levels decreased and time of …

Development And Implementation Of It-Enabled Business Processes: A Knowledge Structure View, Rick Brattin

Graduate Theses and Dissertations

As competitive pressures mount, organizations must continue to evolve their business processes in order to survive. Increasingly, firms are developing new IT-enabled business processes in response to rising competition, greater customer expectations, and challenging economic conditions. The success rate of these projects remains low despite much industry experience and extensive academic study. Managerial and organizational cognition represents a potentially fruitful lens for studying the design and implementation of IT-enabled business processes. This view assumes that individuals are information workers who spend their days absorbing, processing, and disseminating information as they pursue their goals and objectives. Individuals develop cognitive representations, called …

Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, Andrew Heathcote, Ami Eidels, J. T. Townsend

Psychology Faculty Publications

Much of scientific psychology and cognitive science can be viewed as a search to understand the mechanisms and dynamics of perception, thought and action. Two processing attributes of particular interest to psychologists are the architecture, or temporal relationships between sub-processes of the system, and the stopping rule, which dictates how many of the sub-processes must be completed for the system to finish. The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a mental process model. Thus far, statistical analysis of the SIC has been limited to null-hypothesis- significance tests. In this talk …

The Effects Of An Online Sleep Hygiene Intervention On Students' Sleep Quality, Giuliana Farias

Psychology Theses & Dissertations

Students in college or in their first year of medical school undergo increased educational and social pressure. To cope, students may sacrifice sleep to meet demands. Poor sleep affects learning, performance, and health. Studies have been successful at improving sleep quality through the use of in-person recruitment or cognitive-behavioral therapy delivered over the internet (Trockel, Manber, Chang, Thurston, & Tailor, 2011). The purpose of the current study was to investigate whether an online sleep hygiene intervention could improve sleep quality. One hundred thirty-eight students from one undergraduate institution in Southeast Virginia completed this study. Students were divided into groups; one …

Exploration Of Sensemaking In The Education Of Novices To The Complex Cognitive Work Domain Of Air Traffic Control, Travis J. Wiltshire

Doctoral Dissertations and Master's Theses

Many current complex business and industry jobs consist primarily of cognitive work; however, current approaches to training may be inadequate for this type of work (Hoffman, Feltovich, Fiore, Klein, & Ziebell, 2009). To try and improve training and education for cognitive work, Klein and Baxter (2006) have proposed cognitive transformation theory (CTT), a learning theory that claims that sensemaking activities are essential for acquiring expertise that is adaptive and thus well suited for cognitive work domains. In the present research, cognitive task analysis methods were used to identify and assess sensemaking support in the instruction and learning of complex concepts …

The Effects Of Expertise And Information Location On Change Blindness Detection Within An Aviation Domain, Dinorah Zárate

Doctoral Dissertations and Master's Theses

Change blindness is a phenomenon where the viewer fails to detect change in an object or scene during a visual disturbance. During a flight, a pilot samples multiple displays for information about the task at hand. It is imperative that the changes in the displays are being correctly viewed by pilots to ensure a safe flight. However, it is unknown how much change blindness affects pilots or if pilot expertise plays a role in change detection.

A change blindness experiment was performed with twenty four participants divided into two groups based on expertise. Expert pilots were defined as instructor pilots …

The Effects Of Diagrams And Relational Complexity On User Performance In Conditional Probability Problems In A Non-Learning Context, Vincent J. Kellen

College of Computing and Digital Media Dissertations

Many disciplines in everyday life depend on improved performance in conditional probability problems. Most adults struggle with conditional probability problems and several prior studies have shown participant accuracy is less than 50%. This study examined user performance when aided with computer-generated Venn and Euler type diagrams in a non-learning context. Despite the prevalence of research into diagrams and extensive research into conditional probability problem solving, this study is one of the only studies to apply theories of working memory to predict user performance in conditional probability problems with diagrams. Following relational complexity theory, this study manipulated problem complexity in computer …

Essays On Mental Accounting And Consumers' Decision Making, Ali Besharat

USF Tampa Graduate Theses and Dissertations

This dissertation is structured in the form of two empirical essays, each investigating one type of irrational decision caused by mental accounting. The first essay, titled "Managing the Cost of Multiple Debt Accounts: A Behavioral Perspective", explores why many people pay off credit cards' with the lowest rate first when rationally speaking they should repay the debt with the highest rate most quickly. This essay suggests that irrationality emerges when people seek to close `mental accounts' associated with their credit cards and reduce the total number of outstanding loans rather than decrease the amount of total debt among all credit …

Conversion Theory Through The Cognitive Science Of Religion Lense In A Christian-Muslim Context, Jennifer A. Garcia

Scripps Senior Theses

The Cognitive Science of Religion (CSR) in recent years is beginning to become more popular. This project evolves around the development of the field as well as critiques of the field. Because of the interdisciplinary nature of CSR, it lends an interesting way to understand religion as well as religious experiences. One of those religious experiences, conversion, is examined and explored through the use of conversion narratives from western women who were formally Christian but converted to Islam. Many themes arise out of this research that paves the way for trying to understand religious experiences. Overall, the project focuses on …

Emotion And Inhibition: Pride Versus Happiness, Emery K. Hilles

Scripps Senior Theses

The central question of my thesis is how different positive emotions affect inhibition. Katzir, Eyal, Meiran, and Kessler (2010) addressed this question using an antisaccade task and found that happiness decreased inhibition compared to pride, which they attribute to the links between pride and long-term goals and happiness and short-term goals. I attempted to generalize their results to a color-naming Stroop task and predicted that their results would not generalize because their study had little supporting research and their method had several limitations. I tested 45 students of the Claremont Colleges and found partial support for Katzir et al. Participants …

The Effect Of Affect On Group Memory, Dominick Joseph Atkinson

Undergraduate Honors Thesis Collection

Memory typically improves when recollecting in a group - the larger the group, the better the memory (McClure 2010; Atkinson 2011). High arousal at the time of encoding also improves memory (Bohannon, Gratz, & Cross 2007; Libkumen, et al., 1999). In this study 342 participants viewed either an emotional or neutral slideshow and then recalled either alone or with a group of three (triad). The participants were tested using both probed and free recall questionnaires. We found that for perceptually central items, the emotional material only helped the individuals, and not the collaborative groups. However, for the perceptually peripheral items, …

Measures Of Social Cognition In The Laboratory And Real World: Towards Temporal Dynamics Of Implicit Other-Regard, Danielle Tucci

Scripps Senior Theses

Social cognition is a fundamental aspect of human experience that enables us to have relationships with and understanding of other people. Social relationships have been shown to mitigate cognitive decline in old age and benefit cognitive functioning, and the social interaction on which these relationships rely requires an extensive network of cognitive processes, and by extension neural systems, that have not, as of yet, been widely studied in older adults. Nor has the function of these systems been tied to social relationships in the real world. Here, I will compare self-reports of real-world quality and extent of social networks with …

Vantage Point And Visual Imagery: Effects On Recall In Younger And Older Adults, Allison J. Midden

Scripps Senior Theses

The current study explored the influence of priming vantage point at retrieval on the recall of younger and older adults, in addition to the effects of visualization ability on recall. Based on McIsaac and Eich’s (2002) findings of the effects on younger adults’ recall, it was hypothesized that recollections would be more likely to include certain features when retrieved through the field vantage point (FVP) than through the observer vantage point (OVP) and vice-versa. Additionally, it was expected that older adults would recall more detailed memories from the OVP than from the FVP. Finally, it was hypothesized that visualization ability …

Navigating The Diverse Dimensions Of Stereotypes, With Domain Specific Deficits: Processes Of Trait Judgments About Individuals With Disabilities, Christina G. Boardman

Scripps Senior Theses

Stereotype groups are interrelated. For example, in Australia, New Zealand, and the United States, racial minorities are referred to special education at a much higher rate than are majority racial groups (Tse, Lloyd, Petchkovsky, and Manaia, 2005; Harry, Arnaiz, Klingner, Sturges, 2008). The Stereotype Content Model describes stereotype relationships in terms of an interaction between competence and warmth. Warmth is the more consistent dimension. The nature of competence remains elusive (Fiske, Cuddy, and Glick, 2007; Fiske, Cuddy, Glick, and Xu, 2002). Knowledge of relationships between stereotype groups, which themselves may be effects of bias, could factor into observed competence effects. …

The Story Of Taste: Using Eegs And Self-Reports To Understand Consumer Choice, Charnetta Brown, Adriane B. Randolph, Janée N. Burkhalter

The Kennesaw Journal of Undergraduate Research

The authors investigate consumers’ willingness to switch from a preferred manufacturer brand to an unfamiliar private-label brand if taste is perceived as identical. Consumer decisions are examined through recordings of electrical brain activity in the form of electroencephalograms (EEGs) and self-reported data captured in surveys. Results reveal a willingness of consumers to switch to a less-expensive brand when the quality is perceived to be the same as the more expensive counterpart. Cost saving options for consumers and advertising considerations for managers are discussed.

Longitudinal Changes In Pronoun Reversals In Children With Autism Spectrum Disorder And Typically Developing Children, Michelle Cheng

Honors Scholar Theses

Pronoun reversals occur when a pronoun is incorrectly mapped to the wrong referent. For example, when a child says, “You eat the cookie!” and intended to state that he is eating a cookie. Children with Autism Spectrum Disorder, ASD, are known to be frequent reversers, but their development of these reversals; for example, incidence rate and endpoint, is still unknown. In this study, children interacted with their mothers in a 30-minute play session and their spontaneous pronoun usage were coded for the perspective of the pronoun, type of reversal, and case errors. Children with ASD to their typically developing (TD) …

Habituation Effect In Attention Modification Training For Obsessive-Compulsive Disorder, Olivia E. Bogucki

Honors Scholar Theses

Attention biases influence the type of information that captures an individual’s attention. Cognitive theories of obsessive-compulsive disorder (OCD) state that attention biases cause an increased amount of attention to personally relevant threatening information. Previous studies support this connection, and have examined attention modification training (AMT) as a means to direct attention away from threatening information for various anxiety disorders, including OCD. Results show that attention biases toward threatening information decrease during a single training session of AMT, which may be a result of habituation to threat. However, there is a lack of longitudinal data investigating the number of AMT sessions …

Effort-Related Choice Behavior Is Affected By Pharmacological Manipulations Associated With Depression: The Effects Of Tetrabenazine, Megan Huizenga

Honors Scholar Theses

In humans, psychiatric symptoms such as anergia and psychomotor retardation reflect pathologies in behavioral activation. These motivational symptoms are fundamental aspects of depression and other disorders. Drugs such as reserpine and tetrabenazine deplete monoamines, including dopamine, and induce depressive like behaviors in humans. Our results indicate that administration of low doses of tetrabenazine can alter effort-related choice behavior, biasing animals towards low effort alternatives. These findings may be related to the ability of monoamine depleting agents such as tetrabenazine to blunt behavioral activation and induce psychomotor retardation, anergia and fatigue in humans, and this research could be useful for the …
