摘要
执行功能是一种重要的高级认知加工过程,是为了实现一项特殊目标而将不同的认知加工过程灵活整合并协同操作的功能,而刷新是其功能的一个重要的组成部分。沿用Miyake及Collette的分类,本文着重介绍和讨论了记忆刷新两种主要研究范式:活动记忆范式和n -back范式,并介绍了潜变量分析及认知神经科学研究的新进展,同时简述了心理学认知实验研究中的伦理道德问题,以期望为将来执行功能研究的发展探明可行的方向。
Executive function is an important advanced cognitive process, and it is the function that integrates different cognitive processes to achieve one's aim. Updating is an important component of executive function. According to the classifications of Miyake & Colletee on executive function, two study paradigms on memory updating are discussed: n-back paradigm & running memory paradigm. A new study method called latent variable analysis and new studies of cognitive neuroscience on memory updating are introduced. Issues on ethics and morality in research on cognitive experiment of psychology are briefly demonstrated to explore appropriate direction for research of executive function in future.
