DMIT is the abbreviation of Dermatoglyphics Multiple Intelligence Test. Dermatoglyphics is the study of ridged skin patterns that can be found on fingers, palms, toes and soles. These patterns are formed from the external ectoderm and usually occur during the fetal development stage, 13 to 19 weeks after fertilization. Through research, geneticists have proven that fingerprint formations are contr
olled by chromosomes, and the patterns are influenced by polygenetic inheritance. These genes do not exhibit dominance, and they are very resistant to acquired changes from the environment. Using their morphologies, the patterns can be classified into two categories, namely “ridges” and “furrows”. During the seventh week of pregnancy, vertical thumb creases (thenar contours) begins to appear on the palm of the embryo. Two weeks later, remote and proximal horizontal creases (hypothenar contours) begin to form. Hirsch and Schweicher discovered that prior to the formation of fingerprints, the dermal nerves and blood vessels are arranged in an orderly fashion. This led them to believe that the nervous and vascular systems determine the formation of dermatoglyphics. Consequently, with further research they also established the correlation between the Dermatoglyphics patterns and one’s personalities.
