ABSTRACT

Objective To explore the relationship between digit ratio and personality among male college students of Han nationality. Methods 162 male college students of Han nationality were surveyed with Eysenck Personality Questionnaire. Measurements were taken from the middle of the basal crease to the tip of the finger by electronic vernier caliper. Personality factors scores were compared between male college students of Han nationality and normal. Finger length and digit ratio of the left hand and the right hand were compared among male college students of Han nationality. Correlation coefficient between digit ratio and personality was calculated.Results The male college students of Han nationality showed significantly lower psychoticism (4.53 ± 2. 55 ) and lie (9.64 ± 3. 55 ) than normal ( 5. 96 ± 2.84,12. 17 ± 3.57; t = - 7. 135, - 9. 085 ) , but higher neuroticism ( 12.67 ±3.94) than normal ( 10.63 ±4.44, t=6.573). The length of index finger(2D) & ring finger(4D) and ently higher than those of the right hand (71.74 ± 4. 01 ,74.85 ± 4.41,0. 8973 ± 0. 0306; P ＜ 0.05 ). There was an association of psychoticism with index finger(2D), middle finger(3D), ring finger(4D) and little finger(5D)among male college students of Han nationality ( r=0. 263,0.254,0.248,0.287,0.235,0.243,0.246,0. 283; P＜ 0. 01 ). There was an association of lie with index finger( 2D ), middle finger( 3D), the right ring finger( 4D ) & little finger(5D) among male college students of Han nationality ( r= -0. 208, -0. 213, -0. 185, -0. 226,-0.165, -0. 185; P＜ 0. 05 ). There was an association of neuroticism with the left second to fourth digit ratio ratio is found among male introvert college students of Han nationality. Digit ratio may be correlated with personality among male college students of Han nationality.
