Effect Of Color Overlays On Reading Efficiency, Rhonda Morrison

Open Access Dissertations

Reading is a skill that unlocks the doors of learning and success. It is commonly accepted that reading is a foundational skill that plays a major role in a child's academic success. The history of teaching reading includes many theories about the development of reading, the source of reading difficulties, and interventions for remediation. A large body of research has demonstrated that reading difficulties stem from a phonological basis and interventions that target this area are generally beneficial in helping improving reading skills (National Reading Panel, 2000; Shaywitz, 2003; Stanovich, 1986). However, there are some who even with extensive intervention …

Attention To Television In Preschoolers Who Exhibit Adhd Symptoms: An Erp Investigation, Lindsay B. Demers

Open Access Dissertations

Children with ADHD suffer from low and high order attention deficits. Work by E.P. Lorch and colleagues shows that these attention deficits affect televised narrative comprehension. The purpose of this research was to determine the extent to which the televised narrative comprehension deficits are the result of an inability to inhibit processing of irrelevant information. To achieve this, data were collected from 16 healthy adults and 37 preschool age children who varied in their ADHD symptoms. Participants were instructed to attend to one of two simultaneously presented audio tracks from children's television shows. For all participants the video that matched …

The Interaction Between Endogenous Cortisol And Salivary Alpha-Amylase Predicts Implicit Cognitive Bias In Young Women, Donna Ann Kreher

Open Access Dissertations

Both animal and human studies suggest that cognitive bias toward negative information, such as that observed in major depression, may arise through the interaction of cortisol (CORT) and norepinephrine (NE) within the amygdala. To date, there is no published account of the relationship between endogenous NE and CORT levels and cognitive bias. The present study examined salivary CORT and salivary alpha-amylase (sAA), an indirect measure of NE, in relation to masked affective priming of words in young female participants. Women with higher salivary CORT showed increased priming to negative word pairs only when sAA was also high; when sAA was …

Understanding Combat Related Psychological Difficulties In Veterans: The Role Of Context-Based Morality, Ramila Shadina Ali Usoof

Open Access Dissertations

In five multi-method studies this dissertation examined how context based morality may explain increased incidence of combat related psychological difficulties among US service personnel. We were particularly interested in the relationship between causing harm to others and moral self-perceptions and related emotional consequences. In studies 1 and 2 we found that our samples of Iraq and Afghan war veterans reported that a soldier would feel increased levels of guilt and shame and negative moral judgments of the self when they return home and reflect on incidents of harm that may have occurred during their deployments. These two studies were supported …

Mastering One's Destiny: Mastery Goals Promote Feeling Challenged In Identity Threatening Achievement Contexts, Jane Gage Stout

Open Access Dissertations

Three experiments integrated insights from achievement goal theory, social identity threat, and stress and coping research, to develop a theory-based strategy individuals can use to navigate social identity threat in high stakes achievement settings. In all experiments women were asked to adopt a mastery goal (focus on learning and building skills) or a performance goal (perform well; avoid errors) before a mock job interview. In Experiment 1, women expected their interviewer to be either sexist (creating identity threatening situation) or not sexist (a non-threatening situation). Women who focused on mastery rather than performance goals felt more challenged and less threatened …

Binary Rocs And Their Implications For The Measurement Of Memory, Chad Dube

Open Access Dissertations

Bröder and Schütz (2009) have argued that the curvature typically observed in recognition memory receiver-operating characteristics (ROCs) is a by-product of the ratings task often used to obtain them. According to those authors, ROCs collected by experimentally manipulating response bias are linear and consistent with the assumptions of threshold and multinomial processing tree (MPT) models. Two experiments are reported which are broadly consistent with previous work by Dube and Rotello (under review) in showing that ROCs are curved and consistent with signal detection theory (SDT) regardless of the procedure used to obtain them. These results have implications for how accuracy …

A Multi-Level Investigation Of Teacher Instructional Practices And The Use Of Responsive Classroom, Benjamin George Solomon

Open Access Dissertations

A year-long longitudinal study was conducted to quantify different types of teaching in the beginning of the year, and the effect of those choices on end of year instructional practices and student outcomes. Teacher practices were organized around the fidelity of implementation to the Responsive Classroom (RC) program (Northeast Foundation for Children, 2009). Most notably, a central RC tenant entitled “the first six weeks” was examined. RC is a universal prevention program that previously has been categorized as a Tier I social-behavioral program for students when considered within an RTI model (Elliott, 1999).
