The Electrophysiological And Neuropsychological Organization Of Long Term Memory, Richard J. Addante

Psychology Faculty Publications

The electrophysiological correlates of recognition memory retrieval were examined in order to identify the neural conditions that precede accurate memory retrieval, characterize the processes that contribute to high and low confidence memory responses, and determine which memory processes are impaired after brain injury. Human electroencephalogram (EEG) was recorded during recognition confidence and source memory judgments in three experiments. In Experiment 1, mid-frontal pre-stimulus theta oscillations were found to precede the stimulus presentation of items that were successfully recollected, but they were not found to be predictive of item familiarity. Moreover, during stimulus presentation, recollection was associated with an increase in …

From Nixon’S War On Drugs To Obama’S Drug Policies Today: Presidential Progress In Addressing Racial Injustices And Disparities, Cigdem V. Sirin

Cigdem V. Sirin

This study investigates presidential progress in addressing racial injustices and disparities within the context of the war on drugs. I argue that racial inequalities emanating from the war on drugs have been largely overlooked and at times aggravated by previous administrations. Although there have been some improvements in this regard since President Obama took office, more extensive policy reforms are needed to better remedy such inequalities. I also argue that the viability of a progressive presidency for racial justice vis-à-vis U.S. drug policies depends not only on the personal agenda of the president but also on a supportive public as …

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 …

Examining The Effects Of Political Information And Intervention Stages On Public Support For Military Interventions: A Panel Experiment, Cigdem V. Sirin

Cigdem V. Sirin

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 …

Thinking Like Thinkers: Is The Art And Discipline Of An "Attitude Of Suspended Conclusion" Lost On Lawyers?, Donald J. Kochan

Donald J. Kochan

In his 1910 book, How We Think, John Dewey proclaimed that “the most important factor in the training of good mental habits consists in acquainting the attitude of suspended conclusion. . .” This Article explores that insight and describes its meaning and significance in the enterprise of thinking generally and its importance in law school education specifically. It posits that the law would be best served if lawyers think like thinkers and adopt an attitude of suspended conclusion in their problem solving affairs. Only when conclusion is suspended is there space for the exploration of the subject at hand. The …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

Nice Guys Finish Fast And Bad Guys Finish Last: Facilitatory Vs. Inhibitory Interaction In Parallel Systems, Ami Eidels, Joseph W. Houpt, Nicholas Altieri, Lei Pei, James T. Townsend

Joseph W. Houpt

Systems Factorial Technology is a powerful framework for investigating the fundamental properties of human information processing such as architecture (i.e., serial or parallel processing) and capacity (how processing efficiency is affected by increased workload). The Survivor Interaction Contrast (SIC) and the Capacity Coefficient are effective measures in determining these underlying properties, based on response-time data. Each of the different architectures, under the assumption of independent processing, predicts a specific form of the SIC along with some range of capacity. In this study, we explored SIC predictions of discrete-state (Markov process) and continuous-state (Linear Dynamic) models that allow for certain types …
