Masculine (Low) Digit Ratios Predict Masculine Food Choices in Hungry Consumers
2021
Abstract This study investigated the link between individuals’ 2D:4D digit ratio (a biomarker associated with prenatal testosterone exposure) and their inclination to make masculine food choices. Furthermore, the study investigated whether this potential association would be moderated by consumers’ levels of hunger (vs. satiation). Participants (N = 216; 50% female) made a set of binary food choices between items pretested to be perceived as masculine (vs. feminine) and indicated the lengths of their second (2D) and fourth (4D) digits (i.e., index and ring fingers), which were used to calculate their 2D:4D digit ratios. Additionally, they self-reported their self-perceived gender identity a…
Can Digit Ratio and Gender Identity Predict Preferences for Consumption Options With a Distinct Gender Image?
2022
This study investigated whether individuals’ preferences for masculine (vs. feminine) consumption options could be predicted by a biological sex cue (the 2D:4D digit ratio; a biomarker linked to prenatal testosterone exposure), and a psychological gender cue (self-perceived gender identity). Chinese participants (N= 216) indicated their preferences for a series of binary options that differed in their perceived gender image (e.g., romantic comedy vs. action thriller; pop music vs. hard rock), with one of the options evaluated as relatively more feminine and the other viewed as comparably more masculine. Participants also self-reported their gender identity and the length of their index and …
Decreased prevalence of left-handedness among females with male co-twins: Evidence suggesting prenatal testosterone transfer in humans?
2010
Studies of singletons suggest that right-handed individuals may have higher levels of testosterone than do left-handed individuals. Prenatal testosterone levels are hypothesised to be especially related to handedness formation. In humans, female members from opposite-sex twin pairs may experience elevated level of prenatal exposure to testosterone in their intrauterine environment shared with a male. We tested for differences in rates of left-handedness/right-handedness in female twins from same-sex and opposite-sex twin pairs. Our sample consisted of 4736 subjects, about 70% of all Finnish twins born in 1983–1987, with information on measured pregnancy and birth related factors. Circulatin…
