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

Capacity Coefficient Variations, Joseph W. Houpt, Andrew Heathcote, Ami Eidels, Nathan Medeiros-Ward, Jason Watson, David Strayer
Joseph W. Houpt
The capacity coefficient has become an increasingly popular measure of efficiency under changes in workload. It has been used in applications ranging from psychophysical detection tasks to complex cognitive tasks, as well as in addressing questions in social and clinical psychology. The basic formulation compares response times to each stimulus property (or task) in isolation to response times with all stimulus properties (or tasks) at the same time. A number of variations on the basic capacity coefficient have been used, both in the experimental design and in the calculations, and many more are possible. Here we outline the theoretical reasons …

Teleological Reasoning In Adults: Believing In The Purpose Of Events, Carrie Jeanette Guggenmos
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 …
Asymmetry In Resting Alpha Activity: Effects Of Handedness, Ruth E. Propper, Jenna Pierce, Mark W. Geisler, Stephen D. Christman, Nathan Bellorado
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 …
Beyond Dogma: The Role Of "Evolutionary" Science And The "Embodiment" Of Archetypal Energies, Carroy U. Ferguson
Beyond Dogma: The Role Of "Evolutionary" Science And The "Embodiment" Of Archetypal Energies, Carroy U. Ferguson
Carroy U "Cuf" Ferguson, Ph.D.
At individual and collective levels (locally, nationally, and globally), humanity is currently entertaining many challenges and opportunities for growth. In my view, these challenges and opportunities are connected to Energy shifts that are taking place on the planet, and the inability of some to move beyond dogma in relating to these Energy shifts. By its pre- and proscriptive nature, dogma fosters limiting beliefs that often interfere with how best to relate to these Energy shifts as vibrational beings in an evolving, vibrational world. Here, I want to briefly identify some of the limiting effects of dogma, and the role of …
Frequency-Specificity And Pattern-Specificity Of The Buildup Of Auditory Stream Segregation, David Michael Weintraub
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 …
Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, A. Heathcote, A. Eidels, J. T. Townsend
Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, A. Heathcote, A. Eidels, J. T. Townsend
Joseph W. Houpt
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 …

Stephanie Belhomme
An “information-experience” encapsulated by a technological/digital audio-visual tool presents data and potentially meaningful information to prompt actionable knowledge concerning: “unspoken creative process elements;” their profound impacts on both how well our “physiology of creativity” functions but also; how well foundational creative thinking and behavioral prerequisites (energy, motivation, imagination, and ownership) are leveraged.
The product: 1) introduces the user to one component of the CPS (Creative Problem Solving) Facilitation Process - Exploring the Challenge; 2) features a content specific component which prompts exploration of the many correlations between societal, organizational / community, human physiological / behavioral data, and the direct relationships …
Navigating The Diverse Dimensions Of Stereotypes, With Domain Specific Deficits: Processes Of Trait Judgments About Individuals With Disabilities, Christina G. Boardman
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. …

Fighting The Current: Recalling Specific Self-Relevant Memories, John Walden Ransom
Fighting The Current: Recalling Specific Self-Relevant Memories, John Walden Ransom
Graduate Theses and Dissertations
The present study was designed to address whether recalling specific autobiographical memories is more difficult when they are self-relevant compared to non-relevant. In recent years, a number of experimental studies have indicated that self-relevant memories are more likely to be recalled without a specific time frame or very much detail. Unfortunately, these findings have not been integrated into the popular executive resources theory of autobiographical memory recall or theories of independent semantic and episodic memory stores. This study tested the hypothesis that self-relevant memories will be accessed in the semantic store and therefore will require more executive resources to generate …
Temporal Shifts In Weapon Focus: Comparing Retrograde And Anterograde Effects, William Blake Erickson
Temporal Shifts In Weapon Focus: Comparing Retrograde And Anterograde Effects, William Blake Erickson
Graduate Theses and Dissertations
When an eyewitness suffers an impairment of memory for a criminal's face because the criminal used a weapon during the commission of the crime, this impairment is called the weapon focus effect. Literature provides two explanations for how this effect arises: some implicate the narrowing of attentional cues to the weapon during the commission of a crime because arousal of the victim increases, while others claim that the weapon is merely a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm taking place in a …
Facial Expression Processing Is Holistic Or Feature-Based Depending On Stimulus Format: Evidence From The Composite Face Illusion And Gaze-Contingent Stimulus Presentations, Emily R. Prazak
Psychology Honors Projects
Controversy exists over whether facial expression recognition is a holistic or feature-based process. The present research explored whether stimulus format (photographic vs. schematic) affects the type of processing used. In a composite/noncomposite expression recognition task, holistic processing was observed for photographic stimuli and feature-based processing was observed for schematic stimuli. Moreover, holistic processing in the photographic condition increased when more than one individual was presented. Results suggest that facial expression processing is holistic under natural viewing conditions and provide a potential resolution to the previous controversy. Such findings may be corroborated by an ongoing follow-up study using gaze-contingent stimulus presentations.
Creation Of False Memories And Beliefs: Expectancy Consistent Errors Based On Gender Stereotypes, Arianna Stelling
Creation Of False Memories And Beliefs: Expectancy Consistent Errors Based On Gender Stereotypes, Arianna Stelling
Undergraduate Theses and Capstone Projects
This study was a series of three experiments which examined the effects of gender stereotypes on the creation of false-memories. Participants were undergraduate students who viewed a short one-scene video depicting a couple on a date. The video featured a man and a woman displaying a mixture of typical, atypical, or a combination of both gender stereotypical behaviors. Following the video, participants completed a quiz to determine whether they created false memories consistent with gender stereotypes. Participants completed an attitudinal scale to gauge their views on gender stereotypes. It was hypothesized that participants would create stereotype- consistent false memories and …
An Erp Study Of Responses To Emotional Facial Expressions: Morphing Effects On Early-Latency Valence Processing, Zoe Ravich
Scripps Senior Theses
Early-latency theories of emotional processing state that at least coarse monitoring of the emotional valence (a pleasure-displeasure continuum) of facial expressions should be both rapid and highly automated (LeDoux, 1995; Russell, 1980). Research has largely substantiated early-latency differential processing of emotional versus non-emotional facial expressions; however, the effect of valence on early-latency processing of emotional facial expression remains unclear. In an effort to delineate the effects of valence on early-latency emotional facial expression processing, the current investigation compared ERP responses to positive (happy and surprise), neutral, and negative (afraid and sad) basic facial expression photographs as well as to positive …
Public Support For Military Interventions Across Levels Of Political Information And Stages Of Intervention: The Case Of The Iraq War, Cigdem V. Sirin
Public Support For Military Interventions Across Levels Of Political Information And Stages Of Intervention: The Case Of The Iraq War, Cigdem V. Sirin
Cigdem V. Sirin
This study examines the effect of political information levels and intervention stages on the formation and continuity of public support for military interventions by analyzing survey data pertaining to the 2003 military intervention in Iraq. The results show that before and immediately after the launch of the intervention, politically uninformed individuals expressed higher support for the war compared to politically informed ones. However, as the intervention proceeded and casualties were incurred, higher rates of decrease in support were observed among the politically uninformed. Politically informed individuals, on the other hand, demonstrated more stable levels of support throughout the course of …

Agenda Setting From The Oval Office: An Experimental Examination Of Presidential Influence Over The Public Agenda, José D. Villalobos, Cigdem V. Sirin
Cigdem V. Sirin
This study employs an experimental approach to isolate and directly test the extent to which presidents can affect public perceptions of issue importance and support for policy action, taking into consideration key factors that condition such effects. Our findings provide new empirical evidence that presidents can, in fact, positively influence public opinion through agenda setting, particularly by increasing the perceptual importance of low salience foreign policy issues. However, the results also indicate that such positive effects do not translate into public support for policy action; instead, presidential appeals actually decrease support. Last, our study offers new evidence that employing bipartisan …

General Recognition Theory Extended To Include Response Times: Predictions For A Class Of Parallel Systems, James T. Townsend, Joseph W. Houpt, Noah H. Silbert
Joseph W. Houpt
General Recognition Theory (GRT; Ashby & Townsend, 1986) is a multidimensional theory of classification. Originally developed to study various types of perceptual independence, it has also been widely employed in diverse cognitive venues, such as categorization. The initial theory and applications have been static, that is, lacking a time variable and focusing on patterns of responses, such as confusion matrices. Ashby proposed a parallel, dynamic stochastic version of GRT with application to perceptual independence based on discrete linear systems theory with imposed noise \citep{Ash89}. The current study again focuses on cognitive/perceptual independence within an identification classification paradigm. We extend stochastic …

Evaluating The Convergent Validity Of The Measure Of Emotional Connotations, Daniel N. Erosa
Evaluating The Convergent Validity Of The Measure Of Emotional Connotations, Daniel N. Erosa
McNair Poster Presentations
The Measure of Emotional Connotations (MEC; Barchard, Kirsch, Anderson, Grob, & Anderson, 2012) is a new test that has been developed to measure the ability to perceive the emotional connotations of written language. To examine its convergent validity, the MEC will be correlated with the two emotion perception tasks on the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT; Mayer, Salovey, Caruso, & Sitarenious, 2003). These MSCEIT tasks are valid tests of emotion perception; thus, strong correlations would provide support for the MEC as a valid test of emotion perception.
Trauma Severity And Defensive Emotion-Regulation Reactions As Predictors Of Forgetting Childhood Trauma, Bette L. Bottoms, Cynthia J. Najdowski, Michelle A. Epstein, Matthew J. Badanek
Trauma Severity And Defensive Emotion-Regulation Reactions As Predictors Of Forgetting Childhood Trauma, Bette L. Bottoms, Cynthia J. Najdowski, Michelle A. Epstein, Matthew J. Badanek
Psychology Faculty Scholarship
Using a retrospective survey, we studied a sample of 1679 college women to determine whether reports of prior forgetting of sexual abuse, physical abuse, and other traumas could be explained by trauma severity and individual differences in the use of defensive emotion-regulation reactions (i.e., repressive coping, dissociation, and fantasy proneness). Among victims of physical abuse (but not sexual abuse or other types of trauma), those who experienced severe abuse and used defensive reactions were sometimes more likely to report temporary forgetting of abuse, but other times less likely to report forgetting. We also found unanticipated main effects of trauma severity …
Predictors Of Bullying In An Adolescent School Sample, Schell Hufstetler
Predictors Of Bullying In An Adolescent School Sample, Schell Hufstetler
Electronic Theses and Dissertations
Author's abstract: Bullying is a pervasive problem in our society. Contributing to this problem is the fact that bullying is not well understood. This makes it difficult to design successful interventions. The current study aims to create a complete picture of bullying in order to increase understanding of this behavior. For this study, 59 adolescents completed a survey packet including measures of bullying behaviors and other variables expected to relate to bullying. The results revealed that bullying is a problem for both genders. Multivariate analyses revealed males to be more directly and indirectly aggressive, but there were no significant gender …
"...Bless Her Little Heart!": The Culture Of Honor And Emotion Recognition, Forrest J. Rackham
"...Bless Her Little Heart!": The Culture Of Honor And Emotion Recognition, Forrest J. Rackham
Electronic Theses and Dissertations
Author's abstract: Some researchers assert that cultural display rules may explain differences in perceiving emotions (Matsumoto, Yoo, & Chung, 2010). The current study examined the display rule of masking within the Southern culture of honor. It was hypothesized that masking within the culture of honor negatively affects emotion perception sensitivity, particularly in the speed and accuracy of recognizing anger. Southern undergraduate students were primed with the culture of honor and then presented with the Emotional Expression Multimorph Task. Participants chose one of the six emotions (i.e., sad, happy, surprise, fear, disgust, or anger). It was hypothesized participants in the masking …
