纵向样本226名婴儿进行了测试，每月的习惯和新奇的偏好任务，同时从3至9个月大的心率记录增强。然后在12个月、18个月和24个月时对婴儿进行Bayley婴儿发育量表II（BSID）和麦克阿瑟沟通发育量表（MCDI）。先前的研究结果，随着年龄的增长，在寻找时间的下降进行了复制。从每月的评估中提取了基于年龄的因素，3至6个月的早期注意因素和7至9个月的晚期注意因素。一个新奇的偏好因素，分组识别性能在4个月和6个月的年龄，也来自。后期注意力因素与BSID精神指数的因子得分呈负相关，新奇偏好总量与MCDI生产分数的因子得分呈正相关。两组婴儿的基础上的发展过程中的变化，从早期注意到后期注意看持续时间聚合：一个集群（n = 150）强烈下降，另一个（n = 50）增加。属于这些集群的婴儿随后在BSID和MCDI结果上都不同，前一个集群显示出明显的优势，随着12至24月龄的结果评估的进展而增加。这一发现得到了随后对完成3至9个月所有测试的婴儿数据的分析的支持。这项研究的结果表明，婴儿期注意力的发展过程是幼儿期认知和语言结果的重要线索。
A longitudinal sample of 226 infants were tested monthly on habituation and novelty preference tasks, augmented with simultaneous heart rate recording from 3 to 9 months of age. Infants were then administered the Bayley Scales of Infant Development II (BSID) and MacArthur Communicative Development Inventory (MCDI) at 12, 18, and 24 months. Prior findings regarding the decline in look duration with age were replicated. Age-based factors were extracted from the monthly assessments, an early attention factor from 3 to 6 months and a late attention factor from 7 to 9 months. A novelty preference factor, which grouped recognition performance at 4 and 6 months of age, was also derived. The late attention factor correlated negatively with a factor score derived from the BSID mental index, and the novelty preference aggregate was correlated positively with a factor score derived from the MCDI production scores. Two clusters of infants were derived based on the developmental course of change from the early attention to late attention look duration aggregates: One cluster (n = 150) decreased strongly, and another (n = 50) increased. Infants belonging to these clusters subsequently differed on both the BSID and MCDI outcomes, with the former cluster showing distinct advantages that increased as the outcome assessments progressed from 12 to 24 months of age. This finding was bolstered by subsequent analyses of data from infants who completed all tests run from 3 to 9 months. The results of this study suggest that the developmental Course of attention during infancy is an important clue to cognitive and language outcomes in early childhood.
