To examine the effects of a cognitive intervention package on the free-throw shooting performance of basketball players, with 3 Canadian male university caliber basketball players ages 20, 22, and 24 years, during practice and in competition single-subject multiple-baseline design was implemented. Each subject was introduced to the imagery-rehearsal intervention at different times during the 14-week competitive basketball season. Free-throw data were collected during 50 practice sessions and 32 games. Data from both practice and competitive situations were examined using a comparison of graphed means. In the practice condition an increase in free-throw performance for all three subjects occurred during the posttreatment intervention. In the game condition, Subjects A and B showed posttreatment improvement. The cognitive intervention package consisting of visualization and relaxation can be an effective strategy for improving free-throw performance of some basketball players. Further research should involve control-group examination using a larger sample across a variety of tasks.
为了研究认知干预方案对篮球运动员罚球投篮表现的影响，对3名年龄分别为20岁、22岁和24岁的加拿大男子大学水平篮球运动员，在训练和比赛期间实施了单受试者多基线设计。在为期14周的竞技篮球赛季中，每个受试者在不同时间接受意象演练干预。在50次训练课和32场比赛中收集罚球数据。通过对图表化均值的比较来检查训练和比赛情况下的数据。在训练条件下，所有三名受试者在治疗后干预期间罚球表现均有所提高。在比赛条件下，受试者A和B在治疗后有所改善。由可视化和放松组成的认知干预方案可能是提高一些篮球运动员罚球表现的有效策略。进一步的研究应包括使用更大样本在各种任务中进行对照组检查。
