Termination locus of palmar main line A of the left hand in relation to mental pathology.
A ridge originating at digital triradius point a (palmar main line A) was measured from photographs in three groups of Ss, each composed of 36 males: 1) chronic, hospitalized schizophrenics; 2) chronic, hospitalized patients classified as nonpsychotic; 3) business and professional men who were members of a service club. Seven naive judges measured the point of exit of main line A at the ulnar edge of the left palm in each of the 108 SS. Results were as follows: (a) Range of scores in units used was 5.00 to 7.75; total variance, .26 (N = 756). (b) Means of the two control groups were identical, but schizophrenic and control group difference failed to meet the .05 level of significance. (c) Very significant differences were found among judges' means. (d) Median interjudge r = about + .69.
