Group identification: Control G (non-guidance students); Classification (students taking test for classification); Practicum (students in practicum or other 550 series course - well along in their program); Control F1 & F2 (undergraduate students, six weeks apart); Pre TM El (students interested in Transcendental Meditation before taking it up) Post TM E2 (Same students six weeks later, after practicing TM); Long time M (students who had been practicing TM an average of 43 months).

m is the (old) self-actualization scale mean on the NDS.
*significant at the 5% level,
**at the 01% level;
***at the 0.1% level.
 

The TM students were generally younger than the classification and practicum students and more often undergraduates. Sex and age were controlled within the TM study, but not in the classification and practicum study.
