目标
典型的智力投入（TIE）与整个生命周期的认知发展有关，但TIE本身的发展尚未得到研究。在本研究中，结构变化，差异变化，绝对变化，分歧的稳定性，以及在4个TIE因素的变化的一般性，抽象思维，解决问题，阅读，并在5年的智力好奇心在老年人进行了检查。
方法
数据来自苏黎世认知老化纵向研究。第一次测量时（2005年）平均年龄为73岁的233人在5年后重新评估。应用了解释性因素分析和潜在变化评分模型。
结果
因子协方差在时间上是相等的，这意味着结构稳定。微分稳定性的系数约为0.80，这意味着解决问题和求知欲的平均水平发生了微小的变化。分歧没有发生变化。各因素之间的变化相关性在中等到大的范围内。
讨论
在5年内，TIE在组水平上保持相对稳定。然而，出现了明显的个体间差异。此外，虽然这些因素的变化有很大的差异，但这些因素的发展并不完全平行。
OBJECTIVES
Typical intellectual engagement (TIE) is related to cognitive development across the life span, but the development of TIE itself has not been examined. In the present study, structural change, differential change, absolute change, stability of divergence, and the generality of changes in the 4 TIE-factors abstract thinking, problem solving, reading, and intellectual curiosity across 5 years were examined in older adults.
METHOD
Data came from the Zurich Longitudinal Study on Cognitive Aging. Two hundred and thirty-three individuals, 73 years on average at first measurement occasion (2005), were reassessed after 5 years. Confirmatory factor analyses and latent change score models were applied.
RESULTS
Factor covariances were equal across time, implying structural stability. Coefficients for differential stability were around .80, implying small significant mean-level changes for problem solving and intellectual curiosity. No changes in divergence emerged. Change correlations between the factors were in the medium to large range.
DISCUSSION
Across 5 years, TIE remained relatively stable on a group level. However, pronounced interindividual differences emerged. Also, although the changes in factors shared a substantial amount of variance, the development of the factors was not completely parallel.
