目前的研究调查了所有四个组成部分的巴德利的[巴德利，A。D.（2000年）的第10/2000号决议。情景缓冲区：工作记忆的一个新组成部分？Trends in Cognitive Sciences，4，417-423]在伴随帕金森病（PD）的计划缺陷中修订的工作记忆模型。根据伦敦塔任务的测量，PD导致计划的制定和执行较差。PD还降低了工作记忆的情节缓冲区和中央执行成分的效率，但不影响言语或视觉空间信息的存储。PD中的计划缺陷与多模态短期信息与长期记忆（情景缓冲）的整合问题特别相关。这些结果强调了整合和执行处理在PD认知问题中的重要性，而不是简单的记忆缺陷。(c)2007爱思唯尔有限公司保留所有权利。
The current study investigated the involvement of all four components of Baddeley's [Baddeley, A. D. (2000). The episodic buffer: A new component of working memory? Trends in Cognitive Sciences, 4, 417-423] revised working memory model in deficits of planning accompanying Parkinson's disease (PD). PD resulted in poorer formulation and execution of plans, as measured by the Tower of London task. PD also reduced the efficiency of the episodic buffer and central executive components of working memory, but did not influence storage of verbal or visuospatial information. Planning deficits in PD were particularly linked to problems in integrating multimodal short-term information with long-term memory (episodic buffer). These results emphasize the importance of integrative and executive processing in cognitive problems in PD, rather than simple memory deficits. (c) 2007 Elsevier Ltd. All rights reserved.
