In this dissertation I report findings from two studies of the literacy abilities of children with Williams syndrome (WS), a genetic disorder associated with intellectual disability. I had two overarching goals: 1) evaluate the applicability of theories of reading and spelling acquisition developed based on typically developing children to…

Simple mean differences summarized in meta-analyses do not always adequately describe sex similarities and differences. We investigated sex similarities and differences in academic achievement test scores during childhood and adolescence multiple ways based on composite and subtest scores from the Kaufman Test of Educational Achievement (Third…

The long-term negative consequences of learning difficulties have been acknowledged. Nonetheless, research is still scarce regarding the prediction of adolescent difficulties in reading and arithmetic skills. The present study examines at which age phase and with what kind of constellation of parent- and child-related factors can adolescent…

This article presents two studies investigating the role of executive functioning in written text comprehension in children and adolescents. In a first study, the involvement of executive functions in reading comprehension performance was examined in normally developing children in fifth grade. Two aspects of text comprehension were…

Despite research demonstrating a strong association between early and later mathematics achievement, few studies have investigated mediators of this association. Using longitudinal data (n = 1,362), this study tested the extent to which mathematics self-concepts, school placement, executive functioning, and proficiency in fractions and division…

Researchers have used various theories to explain deaf individuals' reading skills, including the dual route reading theory, the orthographic depth theory, and the early language access theory. This study tested 4 groups of children--hearing with dyslexia, hearing without dyslexia, deaf early signers, and deaf late signers (N = 857)--from 4…

This study investigated how self-regulation contributes to the development of reading competence in an at-risk sample of 157 children born to adolescent mothers. It was hypothesized that reading readiness at age 5 would shape self-regulation at age 10, which in turn would influence reading competence at age 14. Based on structural equation…
