Approximately 10% of women use cocaine and 20% smoke cigarettes during pregnancy. Animal studies indicate that both cocaine and nicotine are neuroteratogenic agents, although findings with humans are inconsistent. Studies with human infants have been plagued by unreliable subject identification procedures, poor control over confounding factors, and invalid measures of CNS integrity. The literature on prenatal cocaine and nicotine use is reviewed and two studies are presented along with an intriguing case report. The effects of maternal prenatal cocaine use (Study 1) and two levels of cigarette smoking (Study 2) on newborn information processing ability were examined using an auditory habituation-recovery paradigm. Case-control designs were employed in which subjects were individually matched on a number of maternal and infant factors. Cocaine exposure was determined by newborn meconium analysis, urine analysis, and maternal self-report. Maternal smoking was determined by self-report and a variation of the bogus pipeline method. Fetal cocaine- and nicotine-exposure were associated with differential impairments in neonatal information processing. Cocaine-exposed newborns exhibited deficits on measures of habituation and recovery to novelty. Dose-response effects of nicotine-exposure were evident on measures of orientation and habituation, but recovery to novelty was not consistently affected. The results imply that fetal cocaine-exposure severely impairs neonatal auditory information processing ability, whereas fetal tobacco-exposure is associated with deficits in information-processing which may be secondary to impairments in arousal regulation. These auditory processing deficits may be related to the later language impairments reported in follow-up studies with cocaine-and tobacco-exposed infants. Following the two studies, a case is presented of an infant born to a woman who reported using large amounts of cocaine throughout pregnancy, although the infant's meco

Speech perception plays an important role in how infants begin to produce speech. This study aims to understand how changes in infant selective attention to various parts of talking faces guides their understanding of speech and subsequent production. In this study, we tracked infant (4-12 months of age) and adult gaze patterns to determine where on a face they attend, when hearing and seeing the face speak in either their native (English) or a non-native language (Spanish). We also tracked infant selective attention to moving-silent and silent-static faces, to determine if this would result in different patterns of attention. The findings suggest that there are two shifts in infant attention. The first shift occurs between four and eight months of age, with infants shifting their eyes to the mouth of the talking face. The second shift occurs around twelve months of age, when infants begin to return their gaze back to the eye region when hearing and seeing their native language, but continue to attend to the mouth region when hearing and seeing the non-native language. Overall, the results of this study suggest that changes in selective attention to talking faces guides the development of speech production and is dependent on early language experience. / by Amy H.
