The purpose of this study was to investigate changes in mental representation from either random or blocked practice when engaged in golf putting. Thirty participants were randomly assigned to random practice, blocked practice, and no-practice groups. First, we measured novice golfers' initial mental representation levels and required them to perform 18 putting trials as a pre-test. We then asked random and blocked groups to practice in accordance with their group assignment for six consecutive days (10 blocks each day, 18 trials each). A week after the last practice session, we re-measured all participants' final mental representation levels and required them to perform 18 putting trials to evaluate learning retention through practice. While those engaged in the random practice method putted more poorly during acquisition (i.e., practice) than those in blocked practice, the random practice group experienced more accurate retention during the final putting trials, and they showed a more structured mental representation than those in blocked practice, one that was more similar to that of skilled golfers. These results support the acquisition of a rich mental representation through random versus blocked practice.
本研究的目的是调查在进行高尔夫球推杆练习时，随机练习或集中练习对心理表象的影响。30名参与者被随机分配到随机练习组、集中练习组和无练习组。首先，我们测量了新手高尔夫球手的初始心理表象水平，并要求他们进行18次推杆试验作为预测试。然后，我们要求随机练习组和集中练习组按照各自的分组安排连续六天进行练习（每天10组，每组18次试验）。在最后一次练习后的一周，我们重新测量了所有参与者的最终心理表象水平，并要求他们进行18次推杆试验，以评估通过练习后的学习保持情况。虽然采用随机练习方法的参与者在习得阶段（即练习阶段）的推杆表现比集中练习组差，但随机练习组在最终推杆试验中的表现更准确，并且他们表现出比集中练习组更结构化的心理表象，这种表象更类似于熟练高尔夫球手的表象。这些结果支持通过随机练习与集中练习获得丰富的心理表象。
