【摘要】：采用选择/无选范式,借助工作记忆成套测验,在两位数乘法估算问题中探讨了工作记忆系统各成分对不同年龄段个体算术策略运用的预测效应。结果显示:(1)工作记忆的不同成分与年龄之间存在明显的相关。表现为,除视空模板成分外,其他各成分得分随着年龄增长而呈现上升趋势;(2)估算策略运用中,年龄与策略选择显著相关,表现为随着年龄增长,策略选择表现明显提高;(3)估算策略运用中,不同年龄个体的工作记忆不同成分和策略选择表现出不同的联系,中央执行均显示出显著的预测效应,语音环路和视空模板的预测效应均不显著。不同年龄个体的工作记忆不同成分对策略执行的预测效应均不显著。上述发现对于深刻理解工作记忆系统在算术认知策略运用中的作用机制具有重要理论含义。
[Abstract]:Using the selective / non-selective paradigm, and with the help of working memory test sets, In the double digit multiplication estimation problem, the predictive effects of working memory system components on the arithmetic strategies of individuals of different ages are discussed. The results show that there is a significant correlation between the different components of working memory and age. With the exception of the spatial template component, the scores of other components showed an upward trend with the increase of age. In the use of estimation strategies, age was significantly related to strategy selection, which showed that the scores increased with age. In the use of estimation strategies, different components of working memory and strategy choices of individuals of different ages showed different relationships, while central execution showed significant predictive effects. The predictive effects of phonetic loops and visual spatial templates were not significant. The predictive effects of different components of working memory on the implementation of strategies were not significant in individuals of different ages. The above findings were of great significance for the profound understanding of the working memory system in arithmetic cognition. The mechanism of action in the use of strategies has important theoretical implications.
