从长期记忆中提取基本算术事实的能力有助于数学成绩的个体差异，也许还有性别差异。目前的研究追踪了使用检索而不是其他策略来解决个位数加法问题的偏好的共同发展，独立于准确性，以及熟练使用检索（即，准确度和反应时间[RT]）（N = 311）。一年级的准确提取与工作记忆容量和智力有关，并预测二年级的提取偏好。在以后的等级，技能和偏好之间的关系发生了变化，在一个等级的偏好预测的准确性和RT在下一个等级的RT和准确性继续预测未来的收益偏好。与女生相比，男生对检索策略的偏好是一致的，且检索速度更快，但检索准确率的性别差异在年级间存在差异。结果表明，能力的影响早期熟练检索，但实践和技能的影响，在一个反馈回路，在以后的发展，并提供洞察解决问题的方法的性别差异的来源。(C)2012 Elsevier Inc.

The ability to retrieve basic arithmetic facts from long-term memory contributes to individual and perhaps sex differences in mathematics achievement. The current study tracked the codevelopment of preference for using retrieval over other strategies to solve single-digit addition problems, independent of accuracy, and skilled use of retrieval (i.e., accuracy and reaction time [RT]) from first to sixth grades inclusive (N = 311). Accurate retrieval in first grade was related to working memory capacity and intelligence, and it predicted a preference for retrieval in second grade. In later grades, the relation between skill and preference changed such that preference in one grade predicted accuracy and RT in the next grade as RT and accuracy continued to predict future gains in preference. In comparison with girls, boys had a consistent preference for retrieval over other strategies and had faster retrieval speeds, but the sex difference in retrieval accuracy varied across grades. Results indicate that ability influences early skilled retrieval, but both practice and skill influence each other in a feedback loop later in development and provide insights into the source of the sex difference in problem-solving approaches.
