| 摘 要： | 采用两维复杂电脑追踪任务,探讨视觉反馈对结果反馈(KR)时间点适宜值的影响。抽取150名右利手的在校大学生,随机分为3组:KR反馈组、视觉+KR组和视觉组,每组男女各25名。练习持续3天,每天练习30次。练习期间视觉组不获得KR反馈,而KR反馈组和视觉+KR组研究参与者分别在即刻反馈、延迟2 s反馈、4 s反馈、7 s反馈、9 s反馈条件下练习任务。第3天练习结束后休息10min,3组研究参与者进行无KR保持测试。一天后,再进行无KR的保持测试。结果显示:1)个体可以获得视觉反馈时,延迟提供KR有助于技能的学习(在本实验任务条件下延迟7 s为宜),而无法获得视觉反馈时,即刻提供KR利于技能的学习;2)与剥夺视觉相比,获得视觉反馈时,提供KR的适宜时机应延迟。以上结果还提示:视觉等内部反馈信息是自身觉察错误能力形成的信息基础,在无法获得这些关键信息时,个体自身觉察错误能力形成的难度增大。应及时提供KR以帮助个体形成自身的觉察错误能力。

| Abstract: | This study examined the effect of vision feedback on the temporal locus of knowledge of results.150 undergraduates were divided into three groups: KR feedback group,vision +KR feedback group and vision feedback group(each group was gender-balanced designed).During three days of acquisition,KR feedback group and vision + KR feedback group 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,while visi... |
