A fundamental issue in research on infant cognition concerns the consequences of infant abilities for mature intellect. One goal of this proposal is to examine the possibility that core cognitive abilities from infancy, namely, memory,speed of processing, attention, and representation competence persist, and provide the foundation for later intelligence and achievement. A second goal is to examine the extent to which children born at risk (preterms) show deficits in these core cognitive abilities, not only in infancy, but childhood, and the import of early deficits for later outcome. Preterm deficits in childhood will also be examinedfor three overlapping but distinct aspects of executive function, a cognitive domain not studied in infancy. To address these issues we will follow-up, at ages 11 and 13 years, a large cohort (N = 203) of full-terms and preterms (<1750 g birthweight) that were originally tested at 5, 7, and 12 months, and seen at 2 and 3 years to gauge developmental standing (Bayley MDI). The infant tests consisted of a large battery of measures from the same four domains. The battery at 11 and 13 years will include a large number of tasks from the same domains, along with measures of broader outcome, including intelligence, achievement in reading and mathematics, and verbal ability. The results will fill important gaps in knowledge about (1) continuity in core abilities from infancy to later childhood, (2) the possibility that infant abilities form the roots of later outcome, (3) the persistence of specific cognitive deficits in preterms (as well as 'catch-up' and 'sleeper effects'), (4) the role of specific deficits from infancy and childhood in accounting for broader outcomes, and (5) the pathways relating core abilities to broader outcomes. Identifying early antecedents of later deficits has profound implications for intervention, assessment,and remediation, as well as for understanding the nature of the infant mind.

婴儿认知研究中的一个基本问题是婴儿认知的后果 成熟智力的能力。该提案的一个目标是研究核心 从婴儿期开始的认知能力，即记忆力、处理速度、注意力和表现力 能力持续存在，并为以后的智力和成就奠定基础。第二 我们的目标是检查出生在危险中的儿童（早产儿）在这些核心方面表现出缺陷的程度。 认知能力，不仅在婴儿期，但童年，和进口的早期缺陷，为以后 结果。儿童期的早产缺陷也将被检查为三个重叠但不同的 执行功能的各个方面，这是一个在婴儿期没有研究过的认知领域。 为了解决这些问题，我们将在11岁和13岁时随访一个大型队列（N = 203） 最初在5、7和12个月时进行测试的足月和早产儿（出生体重<1750 g）， 并在2岁和3岁时观察，以衡量发育站立（Bayley MDI）。婴儿测试 由来自相同四个领域的大量测量组成。11号和13号的电池 年将包括大量的任务，从相同的领域，沿着的措施， 结果，包括智力、阅读和数学成绩以及语言能力。 这些结果将填补有关以下方面知识的重要空白：（1）核心能力的连续性， 从婴儿期到后来的童年期，（2）婴儿能力形成后来结果的根源的可能性，（3） 早产儿特定认知缺陷的持续存在（以及“追赶”和“睡眠者效应”）， (4)婴儿期和儿童期的特定缺陷在解释更广泛结果方面的作用，以及 (5)将核心能力与更广泛的成果联系起来的途径。识别后来的早期前因 赤字对干预、评估和补救具有深远的影响， 了解婴儿心智的本质
