测验项目反应机制与心理测量模型假设的对应性分析

从测验项目解决的认知过程的视角分析了在不同测验理论框架下的测量模型中的基本假设, 指出测量模型是测验开发者有关测验项目反应机制的理论假设的具体表征, 是系统检验测量假设和过程的统计框架。然而, 不管是经典测验理论、概化理论, 还是早期的项目反应理论模型, 相关假设都过于简化, 缺少相应实质理论的支持。与之相比, 认知测量模型强调与个体在测验项目反应过程中的认知过程、认知策略和知识结构的对应性, 提供了在实质理论基础上界定测量建构、设计测验项目、进行建模分析和解释的可能性, 为日益边缘化的心理测量学和主流心理学研究的融合奠定了基础。

On the Compatibility Between Item Response Mechanism and Assumptions in Psychometric Models

Cast from the perspective of cognitive processing in test item solution,the assumptions underlying psychometric models within various testing theories were analyzed.Although item response mechanism is neglected as definition in CTT and GT,it is included as an integrated component in IRT.Unlike early IRT models where the relevant assumptions are made statistically and lack substantive psychological justifications,assumptions in cognitive psychometric models are explicitly tuned to specific situations of test...
