摘要采用单维简单和两维复杂电脑追踪任务,探讨任务复杂程度对结果反馈(KR)时间点适宜值的影响。100名右利手的在校大学生随机分为:简单任务和复杂任务组(每组男女各25名)。两组受试者分别在即刻反馈、延迟2s反馈、4s反馈、7s反馈、9s反馈条件下,练习简单或复杂任务3d,每天练习30次。第3天练习结束后休息10min,2组受试者进行无KR保持测试。一天后,再进行无KR的保持测试。结果显示:1)延迟KR利于简单任务的技能学习,即刻KR利于复杂任务的技能学习;2)任务复杂程度与KR时间点适宜值存在相互作用,与简单任务相比,操作复杂任务时,提供KR的适宜时机有提前的趋势。以上结果还提示:当信息加工负荷较小(操作任务较简单)时,应延迟提供KR,以促进自身觉察错误能力的形成。而当信息加工负荷较大(操作任务较复杂)时,则应提供即刻KR。 Adopted the single-dimension and two-dimension complicated computer, this study conducted the task complexity and explored the effects of the task complexity on the temporal locus of knowledge of results. 100 college students who prefer to use right hand were divided into two groups by random： simple task group and complex task group （each group was gender- balanced designed）. During two days of acquisition, two groups performed the tracking task with feedback provided under the following conditions：（a） immediate KR, （b） 2s KR-delay, （c） 4s KR-delay, （d） 7s KR-delay, （e） 9s KR- delay. Retention tests of tracking accuracy in absence of KR were administered 10 min and 24 hours following acquisition. And the results showed that ： 1 ） the effect of delayed KR on motor learning is dependent on the task complexity ; 2） there is interaction between the task complexity and the optimum of KR-delay interval. When the subjects operate the complex task, the optimum of KR-delay interval tends to bring forward. Furthermore, the results indicated that providing immediate KR could enhance the development of subjective error-detection capabilities when the processing load is heavy （i. e. operating the more complex task）.
