From novice to no know-how: a longitudinal study of implicit motor learning   总被引:1,自引:1,他引:0  
The aim of this study was to ascertain whether the performances of implicit and explicit learners would converge over an extended period of learning. Participants practised a complex motor skill--golf putting--for 3000 trials, either with a concurrent secondary, tone-counting task (implicit learning) or without such a task (explicit learning). The cognitive demands of the secondary task were predicted to prevent the accumulation of verbalizable rules about the motor task. The implicit group reported significantly fewer rules than the explicit group on subsequent verbal protocols. The performance of the implicit group remained below that of the explicit group throughout the learning phase. However, no significant differences were found between groups during a delayed retention test. Additionally, for the participants in the explicit group only, a Reinvestment Scale score correlated positively with the number of rules accrued and negatively with overall putting performance during the learning phase. We use the results to argue against the excessive use of verbal instruction during skill acquisition, which might be unnecessary and ultimately might hamper performance under stressful conditions.  相似文献

卖显示器需要技术么?需要么?不需要么?虽然以前我不知道答案,但是看到最近一系列关于特丽珑二代显像管的争议,我基本明白了卖显示器ЦЦ还是需要技术的,不过不需要电路设计的技术,需要的只是炒做的技术,也就是概念要大胆,声音要大喊.  相似文献
