【摘要】 以不同认知负荷的连环数认知运算为实验材料,以小学三到六年级175名学生为被试,考察了认知负荷对小学生工作记忆资源分配策略的影响。结果表明:认知负荷的难度明显地影响到了小学生工作记忆资源分配策略。在策略的选择方面,认知负荷对于小学生认知操作成绩的影响力在低年龄段时没有达到显著性差异,而小学六年级则差异显著;在策略的正确率方面,认知负荷难度的影响力随年级的升高而相对减少;在策略的解题速度方面,认知负荷的难度也明显地影响到了小学生工作记忆资源分配策略的解题速度。更多还原

【Abstract】 175 graders from 3 to 6 were selected from one primary school to explored that if and how the cognitive load influenced the strategies selection of pupils’ distributing working memory resources in solving the running- arithmetic problems. The results showed: Intrinsic cognitive load did influence the strategies selection of pupils’ distributing working memory resources. In the strategies selection, cognitive load effected the cognitive performance, but for the lower graders the effect is not remarkable. For the sixth graders, the effect is remarkable. In the accuracy of the strategies, the effect of cognitive load reduced by the grades. And in the efficiency of the strategies, cognitive load did influence the strategies.更多还原
