THE PLAN OF THE RESEARCH INVOLVED PHYSIOLOGICAL AND PSYCHOLOGICAL TESTING OF STUDENTS ENROLLED IN TEACHER EDUCATION, AND SUBSEQUENT EVALUATION BY TRAINED OBSERVERS OF THE TEACHING PERFORMANCE OF THE SUBJECTS. THE SAMPLE WAS LIMITED TO ELEMENTARY SCHOOL TEACHER CANDIDATES BECAUSE OF THE IMPORTANT ROLE THE ELEMENTARY TEACHER PLAYS IN THE MENTAL HEALTH OF THE CHILD. BECAUSE THE MAJORITY OF CANDIDATES WERE FEMALES, THE SAMPLE WAS CONFINED TO WOMEN SUBJECTS. THE SUBJECTS WERE UNIVERSITY WOMEN, MOSTLY JUNIORS, AND CANDIDATES FOR THE GENERAL ELEMENTARY TEACHING CREDENTIAL. THEY WERE DRAWN FROM THE UPPER DIVISION COURSE REQUIRED OF ALL PROSPECTIVE ELEMENTARY TEACHERS. PARTICIPATION IN THE PHYSIOLOGICAL TESTING WAS REQUIRED AS A PART OF THE TESTING PROGRAM FOR ALL SUCH TEACHER-CANDIDATES. FOR THESE 279 SUBJECTS, ADEQUATE PHYSIOLOGICAL DATA WERE OBTAINED FOR 247, AND ADEQUATE PSYCHOLOGICAL DATA AND EVALUATIONS OF STUDENT TEACHER PERFORMANCE WERE OBTAINED FOR SOMEWHAT SMALLER NUMBERS. ONLY AS STRESSES ACCUMULATE AND ATTRITION OCCURS WILL IT BE POSSIBLE TO TEST THE HYPOTHESES WHICH INDUCED THIS STUDY. ONLY LATER, THEN, CAN THE VALUE OF THIS STUDY FOR EDUCATION BE ASSESSED. (JL)
