摘要
采用两维轨迹追踪任务探讨KR延迟对复杂追踪任务技能学习的影响,以及KR延迟间隔长度的合理值。50名右利手的在校大学生(男30名,女20名)随机分为5组,分别在即刻反馈、2 s反馈、4 s反馈、7 s反馈、9 s反馈条件下,练习7天。第7天练习后,休息10min进行无KR保持测试。第8天进行无KR的保持测试和迁移测试。研究显示:延迟KR不利于两维复杂追踪任务技能的学习。
The study examines the effect of knowledge of results (KR) delay on the learning of complex tracking tasks, and the optimum KR-delay interval. 50 college students were randomly divided into five groups and were trained under the conditions of instant KR, 2sKR, 4sKR, 7sKR and 9sKR for seven days. After seven days the students were asked to do the non-KR maintaining test after a ten-minute rest. On the 8^(th) day, they were asked to do the non-KR maintaining tes tand the transfer test. The results show that KR delay is not good for the learning of complex two-dimensional tracking tasks.
