Recent studies of exceptional language development and functioning in mentally retarded people raise questions regarding basic issues in language disorders. These studies are summarised and their implications discussed. Possible reasons for the existence of such cases are examined including language training, general cognitive functioning, working memory, cerebral dominance, and deep-seated var...

Findings from developmental biology studies involving pregnant rats flown on the Space Shuttle are enhancing understanding of the role of gravity in mammalian development. In addition to showing that pregnancy and gestation can withstand the challenge of microgravity, the studies provide the first scientific evidence that early development of the vestibular system—which senses gravity and regul...

Developmental disabilities and severe mental illness are costly to the affected individual and frequently to their family as well. Little studied are their nondisabled siblings. Here we examine major life course outcomes (education, employment, and marriage) of these siblings in adulthood using data from the Wisconsin Longitudinal Study. Our sample comprises 113 individuals with developmental d...
