调节唤醒的能力是一项重要技能，对发展有着广泛的影响。在这项研究中，作者使用“静止面部”程序检查了107名4个月大的婴儿的唤醒调节作为产前可卡因暴露水平的函数。面部表情被编码。与未接触可卡因的婴儿相比，大量接触可卡因的婴儿在与母亲面对面玩耍时表现出较少的乐趣，并且在互动中断后的一段时间内恢复玩耍时继续表现出消极的表情。这一发现是独立的其他物质暴露，新生儿的医疗条件，环境风险，产妇的应急反应，并同时产妇的敏感性和发声。
The ability to modulate arousal is a critical skill with wide-ranging implications for development. In this study, the authors examined arousal regulation as a function of levels of prenatal cocaine exposure in 107 infants at 4 months of age using a "still-face" procedure. Facial expressions were coded. A greater percentage of heavily cocaine-exposed infants, compared with those who were unexposed to cocaine, showed less enjoyment during en face play with their mothers and continued to show negative expressions during the resumption of play following a period when the interaction was interrupted. This finding was independent of other substance exposure, neonatal medical condition, environmental risk, maternal contingent responsivity, and concurrent maternal sensitivity and vocalizations.
