本研究调查了236名8个月和18个月大的婴儿的认知功能。37名婴儿在子宫内大量接触可卡因，30名婴儿轻度接触可卡因，169名婴儿没有接触可卡因。认知功能用贝利婴儿发育量表（第二版; N. 1993年，《两个时代》。婴儿的信息处理也进行了评估与婴儿控制的习惯化程序。结果表明：（a）可卡因滥用妇女的婴儿具有较高的新生儿医疗和环境风险评分;（B）在8个月时，暴露组在心理发育指数、精神发育指数（MDI）评分或对新刺激的恢复方面没有差异;（c）严重暴露于可卡因或高环境风险的婴儿在8至18个月时MDI评分下降。这些结果是在新生儿医疗和环境风险以及多种药物暴露得到控制时获得的。
This study examined the cognitive functioning in 236 infants at 8 and 18 months of age. Thirty-seven infants were heavily exposed to cocaine in-utero, 30 were lightly exposed, and 169 were not exposed to cocaine. Cognitive functioning was evaluated with the Bayley Scales of Infant Development (2nd ed.; N. Bayley, 1993) at both ages. Infant information processing was also assessed with an infant-controlled habituation procedure. Results indicated that (a) infants of cocaine-abusing women had higher neonatal medical and environmental risk scores; (b) at 8 months, exposure groups did nor differ in Psychomotor Development Index, Mental Development Index (MDI) scores, or recovery to a novel stimulus; and (c) infants heavily exposed to cocaine or high environmental risk had a decrease in MDI scores from 8 to 18 months. These results were obtained when neonatal medical and environmental risk, as well as polydrug exposure, were controlled.
