It has been widely recognized that a visual impairment can limit an individual's ability to learn through visual observations. This decreased limited visual access which could impact how the skills to access and recognize the world around them develop. However, when the visual impairment was brain-based, such as in Cortical/Cerebral Visual…

Intelligence tests are important tools in psychology and education; however, the stability of scores and use of intelligence tests has always been surrounded by some controversy. Since its conception in 1905, intelligence testing has become one of the most prominent tasks for school psychologists worldwide. Today's need for frequent use of…

Identifying gifted students early is important so they may receive adaptations in their learning environment including admittance into gifted programs (Subotnik, Olszweski-Kubilius, & Worrell, 2012). An effective method to increase the likelihood of identifying gifted students is needed (Pfeiffer, 2003). Admission at the elementary level…

This study examined the use of a brief writing intervention, Writing Our Stories (WOS), as it relates to delinquency, impulsivity, and IQ in a sample of detained adolescent males. The oppositional and unruly subscales of the Millon Adolescent Clinical Inventory measured the construct of delinquency, and the Wechsler Abbreviated Scale of…

Reading is an essential skill needed for academic success. It is an area experiencing much attention given the research supporting the need to be proficient in reading, specifically reading at grade level, as this has shown to contribute to graduation rates, performance on state exams, and career success. Those experiencing a reading disability…

It is widely believed that subscores can give us more information about an examinee. Thus they can be useful in planning instructional and remedial efforts, or making vocational or academic placement decisions. However, past research has shown that subscores are often not as useful as hoped either because they do not have high reliability or…

Pseudowords (words that are not real but resemble real words in a language) have been used increasingly as a technique to reduce contamination due to construct-irrelevant variance in assessments of verbal fluid reasoning (Gf). However, despite pseudowords being researched heavily in other psychology sub-disciplines, they have received little…

Working memory (WM) has long been associated with deficiencies in reading. Approximately 35% of students in the United States who receive special education services do so under the category of specific learning disability (SLD). The study's theoretical underpinning was Baddeley's model of WM; previous research revealed a significant literature gap…

Student teaching provides the final pre-service clinical teaching experience of an initial teacher preparation program. Research that specifically studies the pre-service student teacher and predictive factors of student teaching is limited. Identifying predictive factors that contribute to the success of student interns' student teaching…

The present study investigated the stability of scores on the WISC-IV and WAIS-IV over an approximate six-year period. Previous research using older versions of the WISC and WAIS have suggested that these scales demonstrate strong stability of scores. Since research that has compared the stability of scores between the WISC-IV and the WAIS-IV is…

The purpose of this study was to examine the validity of teacher ratings for screening children's language skills. Teacher ratings were measured through the use of two tools, the "Children's Communication Checklist-2" (CCC-2; Bishop, 2006) and the "Teacher Rating of Oral Language and Literacy" (TROLL; Dickinson, McCabe, &…

A total of 52 Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV) protocols, administered by graduate students were examined to obtain data on the type and frequency of examiner errors, the impact of errors on resultant test scores as well as improvement rate over the course of two years in training. Findings were consistent with…

Descriptive analyses: Approximately one-third of the nearly 7,500 utterances spoken by teachers were comments. Differences in the use of instructional strategies and content emerged in relation to curriculum condition. In contrast to the variability between teachers, little within-teacher variability was observed. On average, teachers used only…

Every widely used psychological assessment instrument is under scrutiny in terms of cultural fairness. The expectation of the reduced-language (Nonverbal) section of the Stanford-Binet Intelligence Scales, Fifth Edition (SB5; Roid, 2003) is that language ought not to be a modifying factor in terms of final score. The purpose of the present study…

This dissertation examines the determinants of student outcomes--achievement, attainment, occupational choices and earnings--in three different contexts. The first two chapters focus on Ghana while the final chapter focuses on the US state of Massachusetts. In the first chapter, I exploit the incidence of famine and malnutrition that resulted to…
