An investigation of increased rates of autism in U.S. public schools

This study is intended to enhance our understanding of the dramatic increase in autism prevalence rates across the United States. A robust national and multistate sample of children and youth (5–22 years of age) was gathered and analyzed, using visual and statistical analysis of autism eligibility over a 15‐ to 17‐year period. Although the impact of environmental or genetic influences cannot be entirely ruled out, we identified significant shifts in eligibility trends that substantially contribute to the remarkable increase in autism prevalence. Assessment procedures and criteria for autism have sustained an indelible influence from this diagnostic migration, which has had a lasting impact on public schools. We use this information to provide meaningful implications for practicing psychology in the schools.     

Longitudinal pathways to competence and psychological adjustment among African American children living in rural single-parent households

A three-wave model linking maternal functioning to child competence and psychological adjustment was tested with 150 African American families living in the rural South. The children were 11 years old at Wave 1. Structural equation modeling indicated that maternal education and per capita income were linked with maternal psychological functioning (self-esteem, optimism, depression) at Wave 1, which forecast mothers' competence-promoting parenting 1 year later at Wave 2. Competence-promoting parenting forecast child cognitive competence, social competence, and psychological adjustment 1 year later at Wave 3, indirectly through child self-regulation. The data were reanalyzed controlling for Wave 1 child competence and adjustment. All paths remained significant, indicating that the model accounted for change in child competence and adjustment across 2 years.     

How socioeconomic status,executive functioning and verbal interactions contribute to early academic achievement in Chinese children

The present study investigated the relative importance of executive functioning, parent–child verbal interactions, phonological awareness and visual skills on reading and mathematics for Chinese children from low-versus middle-socio economic status (SES) backgrounds. A total of 199 kindergarten children were assessed on executive functioning, verbal interactions, phonological awareness, visual skills, mathematics and word reading in Chinese and English. Results revealed that low-SES children exhibited lower levels of cognitive-linguistic skills, verbal interactions, reading and mathematics achievement than their middle-SES counterparts. Path analyses also indicated that executive functioning and verbal interactions made significant and direct contributions to mathematics, and indirect contributions to reading through phonological awareness. These results suggest that executive functioning and verbal interactions provide the foundation for phonological awareness and visual skills, which in turn affect reading and mathematics achievement. Overall, findings underscore the potential importance of SES inequalities, cognitive-linguistic skills and parental verbal input to their children for early reading and mathematics achievement.     

Socioeconomic status,parent report of children’s early language skills,and late literacy skills: a long term follow-up study among Chinese children

Previous research on the longitudinal prediction of literacy development has focused mainly on the relationship between early cognitive/language skills and late literacy skills. The present study aimed to test the reliability of a number of measures reported by parents as compared to measuring cognitive and language skills in predicting subsequent reading achievement. Two hundred sixty-two Chinese children were administered four cognitive and language skills over three years at the preliterate stage. Additional information on children’s family socioeconomic status (SES), children’s early language skills, familial reading performance and habits, and familial handedness based on the observations of parents was collected. Performance on these variables in relation to subsequent literacy skills at 11 years of age was examined. SES and children’s early language skills significantly predicted subsequent literacy skills. Even with a number of cognitive and language skills statistically controlled, parental reports of children’s early language skills still contributed to reading comprehension. Poor readers defined at 11 years of age had lagged behind in early language skills, as well as family reading performance and habits, as compared to typically developing readers. These findings suggest that SES and parental estimates of children’s early language skills are useful for predicting children’s subsequent reading achievement.     

Anatomists provide the foundation for learning pathophysiology

The need for interdisciplinary graduate training programs which prepare students to conceptualize the application of their research in clinical settings continues to grow. Though several programs have been cultivated to address this need, demand still outweighs supply. The following describes a curriculum developed with the intent of incorporating medical knowledge into a PhD graduate training program. Development of this Molecular Medicine program by the Cleveland Clinic Lerner College of Medicine in collaboration with Case Western Reserve University was funded by the Howard Hughes Medical Institute "Med into Grad" initiative. The core curriculum of this program begins with a foundation in Human Physiology and Disease course in which anatomy faculty introduce students to a basic overview of gross anatomy structure and function. This course is followed by five fundamental basic science courses, a composite course focusing on principles of clinical and translation research, a course on laboratory techniques and three, 12-week research rotations. In the second year of the program, students begin their dissertation research, complete their qualifying examination, and partake in an individually tailored Clinical Experience course. Interdisciplinary graduate programs like this provide another venue for faculty in anatomical sciences to help aspiring translational scientists relate basic science knowledge to human pathophysiology and health.
