Two experiments investigated the relationship between perceptual experience (during practice) and posttest improvements in perceptual accuracy and consistency. Experiment 1 investigated the potential relationship between how often knowledge of results (KR) is provided during a practice session and posttest improvements in perceptual accuracy. Experiment 2 investigated the potential relationship between how often practice (PR) is provided during a practice session and posttest improvements in perceptual consistency. The results of both experiments are consistent with previous findings that perceptual accuracy improves only when practice includes KR and that perceptual consistency improves regardless of whether practice includes KR. In addition, the results showed that although there is a relationship between how often KR is provided during a practice session and posttest improvements in perceptual accuracy, there is no relationship between how often PR is provided during a practice session and posttest improvements in consistency.
两项实验研究了(练习期间的)感知体验与后测中感知准确性和一致性提高之间的关系。实验1研究了在练习阶段提供结果反馈(KR)的频率与后测中感知准确性提高之间的潜在关系。实验2研究了在练习阶段提供练习(PR)的频率与后测中感知一致性提高之间的潜在关系。两项实验的结果均与之前的研究结果一致,即只有当练习包含结果反馈时,感知准确性才会提高,而无论练习是否包含结果反馈,感知一致性都会提高。此外,结果表明,虽然在练习阶段提供结果反馈的频率与后测中感知准确性的提高之间存在关系,但在练习阶段提供练习的频率与后测中一致性的提高之间不存在关系。
