Used psychometric concepts developed by the 2nd author to study the quality of changes in creative functioning resulting from training in meditation. 24 undergraduates who experienced meditation training and 10 undergraduates who experienced training in relaxation were administered the Torrance Tests of Creative Thinking before and after training. Meditators attained statistically significant gains in heightened consciousness of problems, perceived change, invention, sensory experience, expression of emotion/feeling, synthesis, unusual visualization, internal visualization, humor, and fantasy. Relaxation training Ss manifested significant drops in verbal fluency, verbal originality, figural fluency, and figural originality and significant gains in sensory experience, synthesis, and unusual visualization. When the linear models procedure was used to compare the changes, it was found that the changes of the meditation group exceeded those of the relaxation group on perceived change resulting from new conditions, expression of emotion, internal visualization and fantasy.
