Effect of meditation training on aspects of coronary-prone behavior.

52 undergraduates who had volunteered to receive meditation training were placed into either high or low time-urgency groups based on their scores on Factor S of the Jenkins Activity Survey. Subjects then either received training in Clinically Standardized Meditation followed by 3 1/2-wk. of practice or waited for training during that period. Analyses of scores on a time-estimation task and of self-reported hostility during an enforced waiting task indicated that meditation significantly altered subjects' perceptions of the passage of time and reduced impatience and hostility resulting from enforced waiting.
