The Relationship of Finger Length Ratios (2D:4D) with Quantitative, Verbal Talent and Anthropometric Parameters

Abstract

The aim of this study were to investigate the relationship between 2D:4D finger length ratios (the ratio of the second finger length to the fourth finger length) of students from verbal and quantitative weighted fields, and to determine the correlation of these ratios with some anthropometric measurements. For this purpose; hand length, hand width, lengths of second and fourth finger and waist, hip and neck circumferences were taken from totally 398 (199 female, 199 male) students aged 17-25 years by using millimetric callipers and non-elastic standard measuring tape. Demographic data were also taken. Moreover, Body Mass Index (BMI) and 2D:4D finger length ratios of the study group were also calculated. When we investigated the 2D:4D ratios for right, left and dominant hands among verbal and quantitative talented individuals in female students, there were statistically significant differences for right and dominant hand (p=0.032; p=0.042, respectively). On the other hand, there was no difference for left hand in female participants (p>0.05). Furthermore, there were positive correlations with 2D:4D and weight (r=0.38, p<0.001), BMI (r=0.34, p=0.01) of the male students in verbally-weighted field and with hip and waist circumferences in male students in quantitatively-weighted field (r=0.30; p=0.002; r=0.41, p<0.001). In male students in quantitatively-weighted fields, there was a weak and positive correlation with 2D:4D finger length ratios and neck circumferences on the left hand, and this relationship was statistically significant (r=0.21; p=0.032). And also, there were no statistically significant correlations between anthropometric measurements and 2D:4D ratios among the female students in quantitatively weighted field. Whereas there were positive correlations with 2D:4D finger length ratios and waist circumference in female students in verbally-weighted field (r=0.24, p=0.018). We believe that the data obtained in this study will be a guide for career planning goals of persons according to their quantitative and verbal talents.
