Children's Cognitive Ability from 4 to 9 Years Old as a Function of Prenatal Cocaine Exposure, Environmental Risk, and Maternal Verbal Intelligence
Peer reviewed Peer reviewed
Direct linkDirect link
Bennett, David S.; Bendersky, Margaret; Lewis, Michael – Developmental Psychology, 2008
This study examined the effects of prenatal cocaine exposure, environmental risk, and maternal verbal intelligence on children's cognitive ability. Gender and age were examined as moderators of potential cocaine exposure effects. The Stanford-Binet IV intelligence test was administered to 231 children (91 cocaine exposed, 140 unexposed) at ages 4,…

Reactivity and Regulation in Children Prenatally Exposed to Cocaine
Peer reviewed Peer reviewed

Dennis, Tracy; Bendersky, Margaret; Ramsay, Douglas; Lewis, Michael – Developmental Psychology, 2006
Children prenatally exposed to cocaine may be at elevated risk for adjustment problems in early development because of greater reactivity and reduced regulation during challenging tasks. Few studies have examined whether cocaine-exposed children show such difficulties during the preschool years, a period marked by increased social and cognitive…

Arousal Modulation in Cocaine-Exposed Infants.
Peer reviewed Peer reviewed
Bendersky, Margaret; Lewis, Michael – Developmental Psychology, 1998
Examined arousal regulation as a function of levels of prenatal cocaine exposure in 4-month-olds, using a "still face" procedure. Found that, independent of several other factors, a greater percentage of heavily cocaine-exposed infants, compared to unexposed infants, showed less enjoyment during "en face" play with their mothers and continued to…

Children's Intellectual and Emotional-Behavioral Adjustment at 4 Years as a Function of Cocaine Exposure, Maternal Characteristics, and Environmental Risk.
Peer reviewed Peer reviewed
Bennett, David S.; Bendersky, Margaret; Lewis, Michael – Developmental Psychology, 2002
Examined 4-year-olds for effects on IQ of prenatal cocaine exposure, exposure to other substances, risk factors, and neonatal medical problems. Found that maternal verbal IQ and low environmental risk predicted child IQ. Cocaine exposure negatively predicted children's overall IQ and verbal reasoning scores for boys only. Maternal harsh…

Cognitive Functioning in 8- to 18-Month-Old Drug-Exposed Infants.
Peer reviewed Peer reviewed
Alessandri, Steven M.; Bendersky, Margaret; Lewis, Michael – Developmental Psychology, 1998
Compared cognitive functioning of infants--at 8 and 18 months--with varying levels of prenatal cocaine exposure. Found that, with risk and polydrug exposure controlled, exposure groups did not differ at 8 months on Bayley Scales or recovery to a novel stimulus. Infants with heavy exposure or high environmental risk declined in mental development…
