One hundred seven university community participants (71 female, 36 male) were evaluated on the five personality factors (NEO-FFI), and finger lengths were measured to determine the ratio of the second to fourth digit (2D:4D). It is well-established that 2D:4D ratios are an index of prenatal androgenic activity. Sex differences were found such that the men had lower 2D:4D ratios than the women for both the left and right hands, and the women indicated greater Neuroticism than the men, as… 
Emotional stability is related to 2D:4D and social desirability in women: Possible implications on subjective well-being and psychopathology
A positive association is found between 2D:4D and emotional stability, as well as with its subdimensions emotion control and impulse control, but no association was found with the other four dimensions.

2D:4D digit ratio is associated with cognitive decline but not frailty in community‐dwelling older adults
To understand the relation between 2D:4D ratio, frailty, and cognitive decline in community‐dwelling elderly people, a large number of studies have looked at the effects of diet, exercise, and physical activity on the quality of life in the elderly.


Effects of gender and personality on the Conners Continuous Performance Test
Gender differences for the Conners CPT variables were found such that the men were faster and less variable in their reaction times than the women, and the women were more sensitive in terms of signal detection and conservative in their responses than the men.
Masculinized Finger Length Patterns in Human Males and Females with Congenital Adrenal Hyperplasia
Results are consistent with the idea that prenatal androgen exposure reduces the 2D:4D and plays a role in the establishment of the sex difference in human finger length patterns, and finger lengths may offer a retrospective marker of perinatal androgens exposure in humans.
Aggression, gender-typical childhood play, and a prenatal hormonal index
An evaluation was conducted of 134 university students (93 female, 41 male) with the Aggression Questionnaire of Buss and Perry (1992) and a Gender-Typical Play Behavior Questionnaire constructed for
Gender Differences in Relations of Mental Rotation, Verbal Fluency, and SAT Scores to Finger Length Ratios as Hormonal Indexes
Better cognitive performance was associated with a less gender-typical finger-length ratio, for both men and women in this group of college students, and a possible curvilinear relation between hormones and cognition in normal populations is discussed.
Gender Differences in Relational and Physical Aggression
A sample of 134 (93 female, 41 male) university students were evaluated with measures of relational and physical aggression, as well as measures of the five personality factors (NEO Five-Factor
