Finger Length, Digit Ratio and Gender Differences in Sensation Seeking and Internet Self-Efficacy

Several studies have suggested a significant relationship between finger length and aspects of personality. In this study the ratio between second and fourth digit lengths, known as digit ratio, was correlated with sensation seeking and Internet self-efficacy. In addition the relationship between the fourth and fifth digits, i.e. the little finger and ring finger, and these two constructs was also examined. No significant relationship between sensation seeking and digit ratio was observed but, in males, significant correlations between digit ratio and Internet self-efficacy were found. The implications for IT education are discussed.
