Abstract

50 college students practicing the Transcendental Meditation and TM-Sidhi program were administered the Culture Fair Intelligence Test and Group Embedded Figures Test. Significant longitudinal increases over a 3- to 5-yr. period were found in performance on both measures. In the context of normative data, these findings indicate that the practices contribute to an increase in the effectiveness of cognitive ability and cognitive style. The results are consistent with previous findings on the positive effect of the Transcendental Meditation and TM-Sidhi program on these variables in an educational setting.
