关于母亲产前压力与婴儿特定认知过程--学习和记忆--之间的关系知之甚少。采用改良的婴儿床移动的任务进行纵向设计,以测试母亲产前皮质醇,产前主观压力和焦虑,心理社会变量,以及3和5个月大的婴儿的学习和记忆之间的关系。结果显示,产妇产前皮质醇受特定的心理社会变量(例如,母亲的年龄,婴儿的祖母是否提供儿童保育,经济状况),但与母亲的抑郁,焦虑和压力无关。虽然母体产前皮质醇不能预测5个月大婴儿的学习或记忆表现,但母体基础皮质醇水平较高和产前皮质醇反应降低可预测3个月大婴儿的一些学习和短期记忆指标。这些结果表明母体神经内分泌功能对胎儿神经系统发育的影响,以及单独检查主观和生物应激措施的重要性。
Little is known about relations between maternal prenatal stress and specific cognitive processes—learning and memory—in infants. A modified crib‐mobile task was employed in a longitudinal design to test relations between maternal prenatal cortisol, prenatal subjective stress and anxiety, psychosocial variables, and learning and memory in 3‐ and 5‐month‐old infants. Results revealed that maternal prenatal cortisol was affected by particular psychosocial variables (e.g., maternal age, whether or not the infant's grandmother provided childcare, financial status), but was unrelated to measures of maternal depression, anxiety, and stress. Although maternal prenatal cortisol was not predictive of learning or memory performance in 5‐month‐old infants, higher levels of basal maternal cortisol and reduced prenatal cortisol response was predictive of some learning and short‐term memory measures in 3‐month‐old infants. These results suggest an influence of maternal neuroendocrine functioning on fetal neurological development, and the importance of separate examination of subjective and biological measures of stress.
