A major concern of occupational therapy is the identification of context characteristics that optimize performance. The purpose of this study was to examine the effect of context on skill acquisition and transfer.
Forty college students without disabilities (12 men, 28 women) were randomly assigned to the task of learning to use chopsticks in either a natural or a simulated context. Each participant practiced 60 trials in an acquisition phase on 1 day and was tested on a transfer task 24 hr after the acquisition phase. Their performances in the acquisition and transfer phases were measured with the variables of success rate and reaching kinematics.
The natural context elicited significantly larger improvement of success rate in the acquisition phase and a significantly higher success rate in the transfer phase than the simulated context. No major difference was found in kinematic variables between the two contexts.
These results suggested the use of natural contexts to facilitate the outcome of motor skill learning.
职业治疗的一个主要关注点是确定能优化表现的情境特征。本研究的目的是检验情境对技能习得和迁移的影响。
40名无残疾的大学生(12名男性,28名女性)被随机分配到在自然情境或模拟情境中学习使用筷子的任务。每位参与者在一天的习得阶段练习60次,并在习得阶段后24小时接受迁移任务测试。通过成功率和伸手运动学变量来衡量他们在习得和迁移阶段的表现。
与模拟情境相比,自然情境在习得阶段引发的成功率显著提高,在迁移阶段的成功率也显著更高。两种情境在运动学变量上未发现主要差异。
这些结果表明使用自然情境有助于提高运动技能学习的效果。
