项目摘要

Although the increase in intra-subject variability has been identified in ageing research as a reliable predictor of cognitive decline, hardly anything is known about the relevance of decreases in intra-subject variability as predictor of cognitive development during childhood and adolescence. Starting with the established relevance of working memory capacity and processing speed for intellectual development, the proposed research aims to compare different structural equation models that assign different roles to the three constructs working memory capacity, processing speed and intra-subject variability of processing speed with regard to the prediction of the development of general intelligence, thereby distinguishing different facets of intra-subject variability. While a relatively broad age range (6-18 years) will be investigated cross-sectionally, proper cause-effect relationships will be investigated longitudinally over two years in a narrower, early age range (6-7 years).Data analysis will employ MIMIC models for the cross-sectional data, and Dual change score models as well as continuous time models for the longitudinal data. Overall, we expect this project to yield new basic knowledge about central factors of cognitive development and to enlighten the developmental dynamics of important constructs of Differential Psychology. The results of this project will therefore contribute to the further development of developmental and differential theories, demonstrate the applicability of innovative methods of developmental psychology, and provide an important basis for the further investigation of cognitive anomalies in psychiatric disorders of childhood and adolescence.

虽然在老龄化研究中，受试者内变异性的增加已被确定为认知能力下降的可靠预测因子，但几乎没有任何关于受试者内变异性的减少作为儿童和青少年时期认知发展预测因子的相关性。从工作记忆容量和加工速度与智力发展的相关性出发，本研究旨在比较不同的结构方程模型，这些模型为工作记忆容量、加工速度和加工速度的受试者内变异性这三个结构分配了不同的角色，从而区分受试者内变异性的不同方面。虽然将对相对较宽的年龄范围（6-18岁）进行横断面研究，但将在较窄的早期年龄范围（6-7岁）内对适当的因果关系进行为期两年的纵向研究。数据分析将对横断面数据采用MIMIC模型，对纵向数据采用双变化评分模型和连续时间模型。总的来说，我们希望这个项目产生新的认知发展的核心因素的基础知识，并启发差异心理学的重要结构的发展动态。因此，该项目的结果将有助于发展和差异理论的进一步发展，展示发展心理学创新方法的适用性，并为进一步调查儿童和青少年精神障碍中的认知异常提供重要依据。
