摘要
以128名小学2～5年级儿童为被试,采用BST实验任务,对策略成功基础率变化进行控制,探讨了小学儿童策略适应性差异和发展特点。结果表明:(1)在策略成功基础率变化的情况下,小学儿童策略适应性存在年级差异,表现为2年级儿童策略适应性水平低于3年级儿童,2.3年级儿童策略适应性水平低于4、5年级儿童。(2)小学儿童策略适应性发展存在阶段性,儿童在小学2～5年级内策略适应性发生了质的变化,但是这种变化是一种渐进的发展变化过程,表现为从小学2年级到4年级儿童的策略适应性呈现显著的、渐进的变化,4、5年级之间儿童策略适应性处于稳定状态。
With the base-rate of success controlled, BST tasks were used to examine the developmental differences in primary chihlren＇s strategy adaptivity. The participants were 128 grade 2-5 chihlren. The resuhs indicated： （1） there was grade difference in chihlren＇s strategy adaptivity, namely, chihlren of grade 2 were lower than those of grade 3 in strategy adaptivity, and chihlren of grade 2 and 3 were. lower than tho.se of grade 4 and 5 in strategy adaptivity. （2） chihlren＇s strategy adaptivity developed from phase to phase, which changed qualitatively. Children of grade 2 to 4 showed a significant and gradual trend, and ehihlren of grade 4 to 5 were in stable state.
