The neurodevelopmental sequelae of early deprivation were examined by testing (N = 132) 8- and 9-year-old children who had endured prolonged versus brief institutionalized rearing or rearing in the natal family. Behavioral tasks included measures that permit inferences about underlying neural circuitry. Children raised in institutionalized settings showed neuropsychological deficits on tests of visual memory and attention, as well as visually mediated learning and inhibitory control. Yet, these children performed at developmentally appropriate levels on similar tests where auditory processing was also involved and on tests assessing executive processes such as rule acquisition and planning. These findings suggest that specific aspects of brain-behavioral circuitry may be particularly vulnerable to postnatal experience.
通过测试(N=132),研究了早期剥夺的神经发育后遗症,这些儿童经历了长时间或短暂的机构化养育或在亲生家庭中养育。行为任务包括可以推断潜在神经回路的测量。在机构化环境中长大的儿童在视觉记忆和注意力测试、以及视觉介导的学习和抑制控制方面表现出神经心理缺陷。然而,这些儿童在类似的测试中表现出与听觉处理相关的、以及评估规则获取和计划等执行过程的测试中,表现出与发展阶段相适应的水平。这些发现表明,大脑-行为回路的特定方面可能特别容易受到产后经验的影响。
