SMALL-GROUP DISCUSSION, TO TRAIN MEMBERS TO WORK AS A LEARNING TEAM, WAS USED TO INVESTIGATE CHANGES IN CLOSED MINDEDNESS, ANXIETY, AND SELF CONCEPT. SEVENTEEN MALE LABOR UNION MEMBERS ENROLLED IN A TWELVE WEEK RESIDENT LABOR EDUCATION PROGRAM AT INDIANA UNIVERSITY, WERE RANDOMLY ASSIGNED TO A EXPERIMENTAL GROUP WHICH ATTENDED A TWELVE WEEK, TWO HOUR SESSION TRAINING COURSE, AND TO A CONTROL GROUP WHICH ATTENDED REGULAR CLASSES IN THE LABOR PROGRAM. A THIRD CONTROL GROUP RECEIVED NO TREATMENT. THE ROKEACH DOGMATISM SCALE, TAYLOR MANIFEST ANXIETY SCALE, AND BUTLER-HAIGH Q SORT WERE ADMINISTERED TO ALL GROUPS BEFORE AND AFTER THE PROGRAM. RESULTS INDICATED THAT (1) NO SIGNIFICANT DIFFERENCES EXISTED IN THE CHARACTERISTICS AFTER THE TREATMENT PERIOD, (2) CHANGE IN THE PREDICTED DIRECTION OCCURRED IN THE EXPERIMENTAL GROUP IN ALL CHARACTERISTICS AND IN ANXIETY IN THE FIRST CONTROL GROUP, (3) NO SIGNIFICANT POSITIVE CORRELATION EXISTED BETWEEN CLOSED MINDEDNESS AND ANXIETY, AND (4) A NEGATIVE CORRELATION DID EXIST BETWEEN CLOSED MINDEDNESS AND ANXIETY AND A POSITIVE SELF CONCEPT. THIS PAPER WAS PRESENTED AT THE NATIONAL SEMINAR ON ADULT EDUCATION RESEARCH, CHICAGO, FEBRUARY 11-13, 1968. (PT)
