本研究的目的是确定与高尔夫推杆性能相关的注意力集中模式。高技能的高尔夫球手（N = 34）进行了评估，使用脑电图（EEG）的运动和颞叶皮层的措施，在3秒之前的高尔夫推杆。球员完成了40，12英尺推杆和性能是衡量厘米误差从洞。分析了EEG的三种测量方法：慢移、40 Hz和相对功率谱;分别代表反应准备、集中唤醒和一般皮层活动。所有三个脑电图测量都表明，当球员准备推杆时，左半球运动皮层活动减少。相对功率测量还显示，运动和颞叶皮层的右半球活动显著增加。在推杆前的最后一秒，右半球阿尔法活动的增加与更少的错误相关并预测更少的错误。当受试者准备推杆时，大脑半球的分化也减少了，运动皮层和颞叶皮层之间存在着很少但重要的差异。一个重要的区别发生在阿尔法波段。在运动皮层中，左半球α随时间显著增加，而在颞叶皮层中，右半球α随着受试者接近中风开始而增加。从本研究和过去的运动研究的注意模式之间存在的差异可能涉及到使用一个与两个手发起的反应。
The purpose of this investigation was to determine the attentional focus patterns associated with golf putting performance. Highly skilled golfers (N = 34) were assessed using electroencephalographic (EEG) measures of the motor and temporal cortices during the 3 s prior to the golf putt. Players completed 40, 12-ft putts and performance was measured in cm error from the hole. Three measures of EEG were analyzed: slow shift, 40 Hz, and relative power spectrum; representing readiness to respond, focused arousal, and general cortical activity, respectively. All three EEG measures suggested a decrease in left hemisphere, motor cortex activity as the player prepared to putt. Relative power measures also showed significant increases in right hemisphere activity in both the motor and temporal cortices. During the last second preceding the putt, increased right hemisphere alpha activity correlated with and predicted less error. Hemispheric differentiation was also reduced as subjects prepared to putt and few, but important, differences existed between the motor and temporal cortices. An important distinction occurred in the alpha band. In the motor cortex left hemisphere alpha increased significantly over time while in the temporal cortex, right hemisphere alpha increased as subjects approached stroke initiation. Differences that existed between the attentional patterns from the present study and past sport studies may relate to the use of one versus two hands to initiate the response.
