Matthews, Karen A.; Volkin, Janice I. – Child Development, 1981
Type A and Type B children's efforts to achieve were investigated. Type A's solved more arithmetic problems than did Type B's in a no-deadline condition. Type A's held a weight, which matched individual hand strength, 50 percent longer than did Type B's. Ambiguous performance criteria seemed to increase Type A efforts to excel. (Author/DB)
