【摘要】：以往动作记忆领域的研究深入探讨了动作记忆操作效应产生的原因,提出了情景整合理论,认为整合是产生这一效应的主要原因。但对于整合的具体过程尚未阐述清楚,对于动作操作过程中不同信息以及不同信息之间的整合机制-也未得以明晰。为了深入解析动作记忆操作效应中的整合机制,本研究实施了两个实验,通过控制情景缓冲器对语词、空间和动作信息的整合,探讨了情景缓冲器在工作记忆操作效应整合加工过程中的作用。实验一采用2编码条件(操作、语词)×2语词和空间一致性(一致、不一致)混合实验设计,其中编码条件为被试间变量,语词和空间一致性为被试内变量,探讨语词、空间和动作信息的整合对操作效应产生的影响。结果表明:操作编码下的再认成绩显著优于语词编码下的再认成绩,即存在显著的操作效应;语词和空间一致的项目的再认成绩显著优于不一致的成绩,操作效应的产生不受语词和空间一致性的影响。在实验一的基础上,实验二增加了干扰任务,采用2有无干扰任务(无干扰、有干扰)×2编码条件(操作、语词)×2语词和空间一致性(一致、不一致)三因素混合实验设计,其中有无干扰任务和编码条件是被试间变量,语词和空间一致性是被试内变量,探讨了情景缓冲器在工作记忆操作效应产生中的作用。结果表明:操作效应的产生受干扰任务的影响,无干扰任务时,操作效应显著;而有干扰任务存在时,操作效应消失。此外,一致性效应也受到干扰任务的影响,与无干扰任务比,有干扰任务时,一致性效应显著减小。本研究证实了情景缓冲器对语词、空间和动作信息的整合促进了工作记忆操作效应的产生;当通过干扰任务抑制情景缓冲器的整合功能时,操作效应消失,语词和空间一致性效应也显著减小。同时,本研究在以往研究的基础上进一步扩充了动作记忆情景整合理论的观点,认为情景整合中应包含不同信息间的整合,信息的整合在操作效应的产生中发挥了重要作用。
[Abstract]:The previous researches in the field of action memory deeply discussed the causes of the effect of action memory, and put forward the theory of situational integration, which was considered as the main reason for the effect. However, the concrete process of integration has not been explained clearly, and the integration mechanism between different information and different information in the process of action operation has not been clarified. In order to analyze the integration mechanism of action memory, two experiments were carried out to control the integration of words, spaces and action information with situational buffers. The role of situational buffers in the process of working memory operation effect integration was discussed. In experiment 1, a mixed design of 2 coding conditions (operations, words) 脳 2 words and spatial consistency (consistent, inconsistent) was used, in which the coding conditions were variables between subjects, and the words and spatial consistency were variables within subjects. The effect of the integration of space and action information on the operation effect. The results show that the recognition score under the operation code is significantly better than the recognition score under the word coding, that is, there is a significant operational effect, and the recognition result of the item with consistent words and space is significantly better than the inconsistent result. The operation effect is not affected by words and spatial consistency. On the basis of experiment 1, the interference task was added in experiment 2. The design of mixed experiment of 2 with or without interference (no interference, interference with interference) 脳 2 coding condition (operation, word) 脳 2 and spatial consistency (consistent, inconsistent) was adopted. Whether there are interference tasks and coding conditions are inter-subjects variables, words and spatial consistency are inter-subjects variables, the role of situation buffers in the operation effect of working memory is discussed. The results show that the operation effect is affected by the interference task, the operation effect is significant when there is no interference task, but the operation effect disappears when the interference task exists. In addition, the consistency effect is also affected by the interference task, compared with the non-interference task, the consistency effect decreases significantly when the task has interference. This study confirmed that the integration of words, spaces and action information by situational buffers promotes the generation of operational effects of working memory, and disappears when the integration function of situational buffers is suppressed by interfering tasks. The effect of word and spatial consistency is also significantly reduced. At the same time, based on the previous studies, this study further expands the theory of situational integration of action memory, and holds that situational integration should include the integration of different information, and the integration of information plays an important role in the production of operational effects.
