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 …

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 …

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 …

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 …

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; …

Evaluating The Effects Of A Job-Aid For Teaching Visual Inspection Skills To University Students, Candice M. Jostad

Dissertations

Visual inspection is the primary method of data analysis used in behavior analysis. Thus, it is important that behavior analysts have the skills necessary for accurate visual inspection. Research has shown that visual inspection can sometimes be unreliable, which has broad implications for the evaluation of treatment effects using this method. Traditional lectures have been shown to be ineffective in teaching visual inspection skills to a satisfactory level, although improvements in visual inspection have been accomplished using statistical methods and aids such as celeration lines superimposed on graphs. However, these methods are not effective when the aids are removed and …

Express Yourself: The Effects Of Body Position On Non-Verbal Communication Of Emotions, Kathryn H. Mgrublian

CMC Senior Theses

Recent research has documented that we tend to use the face to express some emotions, but use the body to express other emotions. To understand the contributions of the body to non-verbal emotional communication, we compared the performance of able-bodied participants who were allowed to express emotions naturally (standing) to able-bodied participants who were confined to a wheelchair. Theories of embodied emotion would predict that restraining the use of the body should change emotion production and communication confidence, especially for body-related emotions. Participants expressed six different emotions in three conditions: 1) naturally, 2) face only, and 3) body only. After …
