数学成绩的个体差异可能源于工作记忆和智力等领域的一般因素。顶叶和额叶脑区与数字处理有关，但这些认知因素对数学处理过程中大脑活动的影响尚不清楚。符号和非符号数字比较的脑机制与工作记忆个体差异的关系。非语言智商和数学成绩进行了调查，以确定与行为和大脑功能的可能联系。许多大脑区域显示出与工作记忆和数字处理相关。对于符号数字，工作记忆与双侧顶叶、颞叶和右额叶区域网络中的大脑活动呈正相关关系。对于非符号的点阵，工作记忆与顶叶和额叶的几个脑区呈负相关。这种关系表明行为和大脑功能测量之间的差异，并指出工作记忆和基本数字处理的重要性。(C)2010年爱思唯尔公司All rights reserved.
Individual differences in mathematics performance may stem from domain-general factors like working memory and intelligence. Parietal and frontal brain areas have been implicated in number processing, but the influence of such cognitive factors on brain activity during mathematics processing is not known. The relationship between brain mechanisms during symbolic and nonsymbolic number comparison and individual differences in working memory. nonverbal IQ and mathematics achievement were investigated to determine possible associations with behavior and brain function. A number of brain areas showed correlations with working memory and number processing. For symbolic digits, working memory showed a positive relationship with brain activity in a network of bilateral parietal, temporal, and right frontal regions. For nonsymbolic dot arrays, working memory showed a negative relationship with several parietal and frontal brain areas. This relationship indicates differences between behavioral and brain function measures and points to the importance of working memory and basic number processing. (C) 2010 Elsevier Inc.
