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

Joseph W. Houpt

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 …

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

Cigdem V. Sirin

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 …

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 …

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, …

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.

Reactivation Of Negated Concepts Over Time, Kevin Autry

Graduate Theses and Dissertations

Research on the mental representation of negated concepts in written texts has yet to reach a consensus about the effects of negation. MacDonald and Just (1989) reported that after reading a sentence with a negation, negated words took longer to recognize than non-negated words, which suggests that the negated concepts became less active. However, Hasson and Glucksberg (2006) found that after reading negative metaphors (e.g., This surgeon isn't a butcher), lexical decisions about words consistent with the affirmative sense of the negated word (e.g., clumsy) took less time than for control words. To reconcile these (and other) incompatible findings, two …

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; …

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 …

The Effect Of Working Memory And Math Ability On Decision Making, Jeremy A. Krause

UNLV Theses, Dissertations, Professional Papers, and Capstones

Previous research has indicated that people use various strategies when making decisions. A majority of the research has involved the idea that people use a heuristic when making decisions. Kahneman and Tversky have illustrated that there are instances that people respond with an answer that appears to be indicative of usage of the representativeness heuristic. One of the purposes of the current paper is to gain insight into the actual strategies that are used in these instances. Another purpose of the current experiment is to see if math ability and working memory capacity influence the strategy that a person selects …

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 …

Development Of The Negative Attentional Bias During Exercise Measure And The Rumination And Escape Thoughts Measure, Katie M. Brown

Masters Theses & Specialist Projects

The primary purpose of this study was to develop a measure to assess negative attentional bias toward changes in bodily sensations during exercise and to examine the reliability and validity of that measure. A secondary purpose was to develop a measure to assess tendencies toward rumination about the changes in bodily sensations and tendencies to have escape thoughts with regard to the exercise bout. While global measures of anxiety, rumination, and escape thoughts already exist, the advantage of these newly developed measures is that they are context specific to exercise. Participants in this study consisted of 329 undergraduate students. The …

The Creative Coach: Exploring The Synergies Between Creative Problem Solving: Thinking Skills Model And Non-Directive Coaching, Trevor J. Mcalpine

Creativity and Change Leadership Graduate Student Master's Projects

This project looks at the similarities and differences between the most recent version of Creative Problem Solving called Creative Problem Solving: Thinking Skills Model and the approach to coaching known as Non-Directive Coaching. Creativity practitioners are challenged to find opportunities of engaging in formal full-blown, group-based Creative Problem Solving sessions. There is a need to find other, less formal ways of helping people use their creativity. The Thinking Skills Model’s design allows it to mesh with the creative process in other content areas by making the basic concepts of Creative Problem Solving transferable to those other contexts. Non-Directive Coaching …

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

Cigdem V. Sirin

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 V. Sirin

Cigdem V. Sirin

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 …

Can Personality Disorder Experts Recognize Dsm-Iv Personality Disorders From Five-Factor Model Descriptions Of Patient Cases?, Benjamin M. Rottman, Nancy S. Kim, Woo-Kyoung Ahn, Charles A. Sanislow

Charles A. Sanislow, Ph.D.

Background: Dimensional models of personality are under consideration for integration into the next Diagnostic and Statistical Manual of Mental Disorders (DSM-5), but the clinical utility of such models is unclear.

Objective: To test the ability of clinical researchers who specialize in personality disorders to diagnose personality disorders using dimensional assessments and to compare those researchers’ ratings of clinical utility for a dimensional system versus for the DSM-IV.

Method: A sample of 73 researchers who had each published at least 3 (median = 15) articles on personal- ity disorders participated between December 2008 and January 2009. The Five-Factor Model (FFM), one …

The Effect Of Caffeine On Relationship Memory, Elsa Carodenuto

Undergraduate Honors Thesis Collection

Recollections of participants’ last failed relationship (first meeting, first kiss, and breakup) were examined as a personal flashbulb memory (FBM). Although FBM is usually caused by arousal at encoding, the effects of arousal at retrieval was investigated by giving participants caffeine to determine its effect on elaboration at recall. 72 Butler students completed a protocol containing narrative and probe sections on each event of their last relationship. Results showed that caffeine enhanced memory of events at retrieval.

Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer

Electronic Thesis and Dissertation Repository

One standard task used to investigate the development of cognitive control is the Dimensional Change Card Sort (DCCS). Performance and patterns of brain activity associated with the DCCS show continued age-related advances into early adolescence. According to many theoretical accounts, the DCCS places demands on a single underlying executive control process. Three experiments examined the possibility that the DCCS places demands on multiple control processes that follow distinct developmental trajectories. In Experiment 1, rule switching and conflict processing made orthogonal contributions to DCCS performance. Rule switching was associated with a cue-locked late frontal negativity (LFN) event-related potential (ERP) and conflict …

Learning Mechanisms For Acquiring Knowledge Of Tonality In Music, Rikka Quam, Matthew Rosenthal, Erin Hannon

Festival of Communities: UG Symposium (Posters)

Most people think that musical knowledge is exclusive to trained musicians. Actually, casual music listeners have implicit knowledge of important structural aspects of music, such as tonality. Tonality contributes to the feeling of anticipation one would experience when hearing someone sing “do re mi faso la ti” without singing the final “do”. Knowledge of tonality may be learned through the statistics of music (Krumhansl, 1990). However, learning mechanisms have rarely been investigated experimentally (Creel et al., 2002). Artificial grammar learning experiments have shown that listeners can acquire highly structured knowledge such as syllable co-occurrence and language syntax through passive exposure. …

Examining The Construct Validity Of The Metaphors Test, Jane Park, Kelly Grob, Yevgeniya Verenikina, Kimberly A. Barchard

Festival of Communities: UG Symposium (Posters)

Emotional Intelligence is a multi-faceted construct. Existing tests do a good job of measuring some aspects of Emotional Intelligence. The Metaphors Test (Barchard, 2004) was designed to measure the ability to decipher the emotional content of ambiguous sentences. This test may measure a new facet of Emotional Intelligence. The purpose of this research was to examine the construct validity of the Metaphors Test as a measure of Emotional Intelligence. Using a sample of 281 undergraduates, the Metaphors Test was correlated with the four branches of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT; Mayer, Salovey, & Caruso, 2004): Perceiving Emotions, Using Emotions …
