Earlier studies addressed the effects of feedback frequency on movement accuracy and consistency. The authors additionally addressed the effects on motor automatization. High error feedback frequencies may induce attentional control processes and impede motor automatization. In a pre-post design, 42 participants were assigned to 2 groups with different feedback frequencies and practiced an arm movement sequence with 760 trials in 5 sessions. The 100% group practiced with feedback on 3 movement reversals of the sequence after each trial. The 14% group practiced with 14% frequency according to a fading schedule. Only the 14% group showed a decrease in dual-task costs indicating an increase in automaticity. Group differences in movement accuracy and consistency were not evident.
早期研究探讨了反馈频率对动作准确性和一致性的影响。作者还探讨了对运动自动化的影响。高错误反馈频率可能会引发注意力控制过程并阻碍运动自动化。在一项前后对照设计中，42名参与者被分为两组，反馈频率不同，并在5个阶段进行了760次试验的手臂动作序列练习。100%组在每次试验后对序列的3次动作反转进行反馈练习。14%组按照递减计划以14%的频率练习。只有14%组的双重任务成本有所下降，表明自动化程度有所提高。两组在动作准确性和一致性方面的差异并不明显。
