本研究采用潜伏生长模型（LGM）研究了婴儿定向/调节（O/R）的变化对幼儿努力控制（EC）的影响，母亲EC对婴儿O/R的发展和幼儿EC的影响，母亲活动时间对幼儿EC的影响，婴儿O/R斜率的变化，以及母亲EC对随后母亲用于分娩活动的时间的贡献。来自158个家庭的母亲在婴儿4个月大时完成了自我报告的EC测量，在婴儿4、6、8、10和12个月大时完成了婴儿O/R测量，在孩子18个月大时完成了幼儿EC测量。当婴儿6个月大时，收集有关母亲在各种互动活动中花费的时间的信息。结果表明，较高的母体EC预测截距的个体间差异（即，较高的母体EC、较高的婴儿O/R截距和较高的婴儿O/R斜率有助于较高的幼儿EC。此外，较高的母亲EC预测更多的母亲花在与婴儿的互动活动和更多的母亲的互动时间与婴儿也有助于较高的幼儿EC后，控制母亲EC。这些发现有助于了解母亲EC的影响，直接和通过母乳喂养，幼儿EC。额外的影响，因为它们是有关的早期发展的监管方面的气质进行了讨论。(C)2010年爱思唯尔公司All rights reserved.
Latent growth modeling (LGM) was used to examine the contribution of changes in infant orienting/regulation (O/R) to the emergence of toddler effortful control (EC), the contributions of maternal EC to the development of infant O/R and the emergence of toddler EC, the influence of maternal time spent in caregiving activities on toddler EC and the slope of infant O/R, and the contribution of maternal EC to subsequent maternal time spent in caregiving activities. Mothers from 158 families completed a self-report measure of EC when their infants were 4 months of age, a measure of infant O/R when their infants were 4, 6, 8, 10, and 12 months of age, and a measure of toddler EC when their children reached 18 months of age. Information concerning maternal time spent in various interactive caregiving activities was collected when infants were 6 months old. Results indicated higher maternal EC predicted interindividual differences in the intercept (i.e., higher intercepts), but not slope, of infant O/R and that higher maternal EC, higher infant O/R intercept, and higher infant O/R slope contributed to higher toddler EC. Furthermore, higher maternal EC predicted greater maternal time spent in interactive caregiving activities with their infants and greater maternal time in interactive caregiving with infants also contributed to higher toddler EC after controlling for maternal EC. These findings contribute to the understanding of the influence of maternal EC, directly and through caregiving, on toddler EC. Additional implications as they are related to early developing regulatory aspects of temperament are discussed. (C) 2010 Elsevier Inc. All rights reserved.
