What is mathematical learning disability (MLD)? The reviews in this special issue adopt different approaches to defining the construct of MLD. Collectively, they demonstrate the current status of efforts to establish a consensus definition and the challenges faced in this endeavor. In this commentary, we reflect upon the proposed pathways to…

Objective: The construct of empathy was examined in 20 boys with gender identity disorder (GID), 20 clinical control boys with externalizing disorders (ECC), 20 community control boys (NCB), and 20 community control girls (NCG). The mean age of the children was 6.86 years (range = 4-8 years). It was hypothesized that boys with GID would show…

The authors performed 5-year prospective follow-up (retention rate = 92%) with an ethnically diverse sample of girls, aged 11-18 years, who had been diagnosed in childhood with attention-deficit/ hyperactivity disorder (ADHD; N = 140) and a matched comparison group (N = 88). Hyperactive-impulsive symptoms were more likely to abate than…

A national survey of 6115 college students indicated that 81.9 percent were drinking at least once a year and 20.2 perent were heavy drinkers. Results are presented for demographic and drinking characteristics, and comparisons with a similar 1974 study are given. (Author/BL)

This study represents the first to assess whether a relationship between manic symptoms and feeding/mealtime behavior problems exists in individuals with ID.

Found that genetic influences accounted for 81 to 94 percent of mean-level difference in behavior problems between two-parent/full sibling, and the mother-only/half sibling groups. Shared environmental influences accounted for 67 to…
