| 摘 要： | 采用单维电脑追踪任务,探讨反馈频率对追踪任务技能学习的影响作用.48名右利手的在校大学生随机分为4组(每组男、女各6人),分别按反馈次数占总练习次数比例的25%、50%、75%、100%的频率方式向各组受试者提供当前反馈.结果显示:①获得阶段,频繁反馈有利于提高操作绩效;②保持阶段,减少反馈频率有利于简单追踪任务技能学习.结论:①当前反馈对于练习者学习动作技能具有很强的指导作用,并且容易使学习者对反馈产生依赖性;②通过减少反馈频率的方式可以减少学习者对反馈的依赖作用;③追踪任务技能学习过程中存在反馈频率适宜值. |

| Abstract: | Relative f requency of feedback is the proportion of feedback presentations to the total number of practice t rials. Cont rary to predictions f rom most t raditional motor learning perspectives (e. g ,Adams ,1971 ; Thorndike ,1927) ,recent evidence suggested that ,compared with practice in 100 % relative f requency condi2 tions ,practice with lower relative f requencies might be beneficial to longer2term retention and learning ,but det rimental to practice performance. In experiment ,authors manipulated the f requency of concurrent feed2 back to discern the effect s on learning. According to the relative f requency of concurrent feedback (25 % , 50 % ,75 % ,100 %) ,participant s ( n = 48 ,24 female) were randomly divided into four groups ,Firstly ,Partic2 ipant s performed a 482t rial acquisition phase in 4 blocks (using the mouse pursuit the moving circle presented on the computer monitor) with concurrent feedback provided under the corresponding conditions. Follow2 ing acquisition ,122t rial retion in absence of feedback were administered at 10min ,24hr. Consistent with the guidance hypothesis ,the result s of experiment indicated st rong guiding effect s of concurrent feedback and st rong dependence on the feedback ,as indicated by participant s ext remely poor performance upon feedback withdrawal in retention. As predicted by the guidance hypothesis ,dependence on the feedback was reduced as result of reducing the f requency of concurrent feedback. |
