Sound/syllable repetitions of 13 young children who stutter were acoustically analyzed to identify differences in second formant (F2) transitions between the stuttered and nonstuttered portions of the words. Findings indicated no significant differences in the frequency of occurrence of missing or atypical F2 transitions for young children at…

Parents (N=100) of children (ages 9 to 13) with or without learning disabilities (LD) responded to a retrospective developmental survey. Parents reported that the children with LD had significantly more neurodevelopmental problems or delays across domains (e.g., language, motor, attention, social behavior) than normal achievers.

Osteoporosis screening of 107 adults, ages 40 to 60, with mental retardation who attended community-based training centers found 21 percent had osteoporosis and 34 percent had osteopenia. The most significant predictor of lower bone mineral densities were Down syndrome, mobility status, and race. (Contains references.) (Author/DB)

This study with 45 institutionalized individuals with mental retardation and self injurious behavior (SIB) calculated conditional probability using sequential analysis techniques. It found that successive episodes of self-injury were sequentially dependent and this association was not related to frequency or rate of occurrence. The best predictor…

Adults with mental retardation (n=22,740) were studied to investigate age-related changes in functioning and their relation to subsequent mortality. Individuals with Down syndrome, compared to non-Down syndrome individuals with mental retardation, were at earlier and higher risk for adaptive regression whether prevalence, incidence, or mortality…
