This study is among the first to examine specific neurobehavioral deficits in children exposed at very low lead levels. A systematic analysis for the presence of a threshold of lead exposure was conducted. The sample consisted of 246 African American, inner-city children from whom blood lead concentrations were assessed at 7.5 years of age. The results(More)
Animal but few human studies have demonstrated gender-influenced differences in outcome related to prenatal cocaine exposure. Pregnant participants in a prospective pregnancy study were interviewed for drug use. Exposure was considered positive if history or laboratory tests were positive. An ordinal measure of exposure was also constructed. Six years(More)
BACKGROUND In contrast to the extensive literature documenting IQ deficits in patients with fetal alcohol syndrome, effects on IQ have not generally been reported for children with alcohol-related neurodevelopmental disorder (ARND). This study examined the role of maternal age, MAST, and quality of parenting in moderating the effects of prenatal alcohol(More)
Most studies of prenatal cocaine exposure have found gestational age or intrauterine growth deficits but few, if any, cognitive effects. In a large, well-controlled study we detected cognitive deficits in relation to heavy cocaine exposure. These findings demonstrate that prenatal exposure to cocaine at sufficiently high doses early in pregnancy has the(More)
OBJECTIVE Evidence that mothers report higher levels of drinking retrospectively than during pregnancy has led some investigators to suggest that women systematically underreport alcohol antenatally and that alcohol-related deficits may actually reflect heavier prenatal exposure. This study is the first to compare the validity of antenatal and retrospective(More)
OBJECTIVE To test the sensitivity and specificity of fatty acid ethyl esters (FAEEs) extracted from meconium to identify alcohol-using pregnant women with a sensitive and specific methodology, gas chromatography-tandem mass spectroscopy (GC/MS/MS). Study design Twenty-seven samples of meconium were obtained from infants from the mixed race community in Cape(More)
The detrimental effects of early exposure to lead are credible and persistent, but there is presently no agreement on a safe threshold for circulating lead levels. Although several research groups have found significantly poorer cognitive performance in children who have whole blood levels as low as 5 microg/dL, most government agencies, including the EPA(More)
Detecting patterns of maternal drinking that place fetuses at risk for fetal alcohol spectrum disorders (FASDs) is critical to diagnosis, treatment, and prevention but is challenging because information on antenatal drinking collected during pregnancy is often insufficient or lacking. Although retrospective assessments have been considered less favored by(More)
This article presents a series of studies on narcissism, a personality syndrome receiving increasing theoretical and practical attention. Four empirical studies were carried out to (a) identify narcissistic acts in everyday life, (b) identify the acts subsumed by dispositions that are seen as central components of narcissism, (c) identify which acts and(More)
This research extends a cognitive-developmental approach to examining age differences in self-representation from adolescence to mature adulthood and later life. The authors suggest that mature adults move from representations of self that are relatively poorly differentiated from others or social conventions to ones that involve emphasis on process,(More)
