Sažetak
Analyses of quantitative dermatoglyphic traits of the digito-palmar complex are studied within a group of 70 persons with superior intelligence (35 males and 35 females) and 400 controls with presumed average values of IQ (200 males and 200 females). Eighteen variables were analysed (ridge count on all ten fingers, ridge count between the palmar triradius a, b, c, and d and atd - angle of the left and right hand) in both groups. The descriptive statistical methods, analysis of variance and discriminant analysis within manifest variables were applied. The research has shown, using analysis of variance, the statistically significant increase, if compared with controls, in FRCR1, FRCR5, c-d-RCR, FRCL1, FRCL5 values, as well as the decrease of atd-angle values on both hands in male with superior intelligence, and the increase in FRCR1, FRCR5 and FRCL1 values, along with the decrease of atd-angles of both hands in female with superior intelligence. Total ridge count (TRC) is increased in group with superior intelligence in both sexes. The atd angle and FRC1 of both hands in males and in females are the main discriminators for classification results of canonical discriminant analysis, for more than 80% of the tested persons. This results highly overcome statistical coincidence. The results point to the possibility of discriminating people with superior intelligence from the average population on the basis of dermatoglyphic status. Regarding the high hereditary determination of quantitative dermatoglyphic traits, we conclude that the difference in dermatoglyphic structure of persons with superior intelligence could be conditioned by hereditary factors.
