任务经验对学习时间分配策略转移的影响The Effects of Task Experience on Strategy Shifts in the Allocation of Study Time

Abstract

本研究采用Dunlosky范式，以80名大学生为被试，选择困难5分和容易1分两类项目，通过4个试次的学习–测试过程，探讨权衡情境下任务经验对学习时间分配策略转移的影响。结果发现，在有提示和无提示条件下，随着任务经验的增加，被试均更多地重学高测试项目，困难5分组实现策略转移的比例分别为58%和39%，容易1分组实现策略转移的比例分别是20%和18%。结果表明：学习时间分配的权衡决策随着任务经验的增加而变化；然而，大部分被试未能实现策略转移。In this study, we adopted the Dunlosky’s paradigm, took 81 college students as the participants and chose two kinds of item (5-point difficult and 1-point easy item) through four study-test trials to explore the effects of task experience on strategy shifts in the allocation of study time under the trade-off situation. The results found that with the increase of task experience, participants selected more high test item to restudy in 2 experiments, the proportions of the strategy shift in 5-point difficult groups were 58% and 39%, the proportions of the strategy shift in 1-point easy groups were 20% and 18%. Those results indicated that the trade-off decision of study-time allocation changed with the increase of task experience, while most of participants failed to complete the strategy shift.
