Your finger length, handedness & chirality!
November 12, 2008
Earlier this year researchers from the University of Melbourne have tested a new method of measuring Mannings ‘finger ratio’. They e.g. found in the hands of 600 students that the hands of right-handed students are characterized by longer fingers in the right hand (compared to the left hand).
|Interestingly, the researchers also observed an effect between hand preference and the index/ring finger ratio. Left-handed subjects appeared to have a more ‘masculine pattern’: they had a lower 2D:4D ratio compared to right-handed subjects. This implicates that relative finger length can predict a person’s gender or their hand preference!
The method of measuring the ‘finger length ratio’ included a tube-test, which was compared with measurements on photocopied hands. The tubes test yielded a longer estimate of ring finger length compared to the photocopy method. Despite this, there was a strong correlation between the tests and both showed an association with gender.
By the way, the link between handedness (laterality) and right-left finger length difference was already noticed a few years ago by a Dutch psychologist, who described that the combination leftward thumb length, finger length & handpalm asymmetry can provide a strong indication for left handedness.
