在两项研究中，我们调查了最近开发的心理测量仪器是否可以区分内在、外在和密切相关的认知负荷。研究 I 揭示了语言学习 (n = 108) 和统计讲座 (n = 174) 的类似三因素解决方案，统计考试成绩与假定代表讲座期间内在和外在认知负荷的因素呈负相关。在研究二中，在示例（n = 18）或示例问题（n = 18）条件下研究贝叶斯定理应用的大学新生比在问题示例（n = 18）或问题问题（n = 20）条件下研究应用的同龄人表现出更好的后测表现，并且上述心理测量工具的稍微修改版本可以帮助研究人员区分内在和外在认知负荷。这些发现为最近对相关认知负荷的重新概念化提供了支持，即指专门用于处理内在认知负荷的实际工作记忆资源。 (C) 2013 Elsevier Ltd. 保留所有权利。
In two studies, we investigated whether a recently developed psychometric instrument can differentiate intrinsic, extraneous, and germane cognitive load. Study I revealed a similar three-factor solution for language learning (n = 108) and a statistics lecture (n = 174), and statistics exam scores correlated negatively with the factors assumed to represent intrinsic and extraneous cognitive load during the lecture. In Study II, university freshmen who studied applications of Bayes' theorem in example example (n = 18) or example problem (n = 18) condition demonstrated better posttest performance than their peers who studied the applications in problem example (n = 18) or problem problem (n = 20) condition, and a slightly modified version of the aforementioned psychometric instrument could help researchers to differentiate intrinsic and extraneous cognitive load. The findings provide support for a recent reconceptualization of germane cognitive load as referring to the actual working memory resources devoted to dealing with intrinsic cognitive load.
