典型的智力投入(TIE)包括对认知要求较高的活动的偏好，并被认为是个体认知能力差异的潜在解释变量。然而，关于TIE的因素结构，它与社会人口变量的关系，以及它对老年智力功能的影响，人们知之甚少。本研究使用了苏黎世认知老龄化纵向研究(ZULU)的364名成年人(65-81岁)的数据，研究了TIE的因素结构，并检验了TIE与结晶智力的关系比老年与流动智力的关系更强的假说。基于四个相关的一阶因素(阅读、问题解决、抽象思维和智力好奇心)的二阶因素的测量模型显示出很好的契合性。在控制了年龄、性别和正规教育后，TIE与晶态智力的相关性比与液态智力的相关性更强，与年轻人的结果相当。更详细的分析表明，这种联系主要是通过阅读和智力好奇心来定义的。
Typical Intellectual Engagement (TIE) comprises the preference to engage in cognitively demanding activities and has been proposed as a potential explanatory variable of individual differences in cognitive abilities. Little is known, however, about the factorial structure of TIE, its relations to socio-demographic variables, and its influence on intellectual functioning in old age. In the present study, data of 364 adults (65-81 years) from the Zurich Longitudinal Study on Cognitive Aging (ZULU) were used to investigate the factorial structure of TIE and to examine the hypothesis that TIE is associated more strongly with crystallized intelligence than with fluid intelligence in old age. A measurement model of a second order factor based on a structure of four correlated first order factors (Reading, Problem Solving, Abstract Thinking, and Intellectual Curiosity) evinced an excellent fit. After controlling for age, sex, and formal education, TIE was more strongly associated with crystallized intelligence than with fluid intelligence, comparable to results in younger persons. More detailed analyses showed that this association is mostly defined via Reading and Intellectual Curiosity.
