General feelings of gratitude,gratitude to god,and hemoglobin A1c: Exploring variations by gender*

Research indicates that feeling grateful is associated with better physical health. However, most studies rely on self-reports of health. The purpose of this study is to see if feelings of gratitude in general as well as feeling grateful to God specifically are associated with a key biomarker of health – hemoglobin A1c (HbA1c). HbA1c is an indicator of blood sugar control. In the process of assessing the relationship between gratitude and HbA1c, an effort is made to see if the relationship between these measures and HbA1c vary by gender. Findings from a recent nationwide survey indicate that women are more likely than men to feel grateful in general and to feel grateful to God. The results further reveal stronger feelings of general gratitude are associated with lower levels of HbA1c. However, this relationship did not differ for men and women. In contrast, feeling grateful to God was associated with lower HbA1c, but this relationship emerged among women only.     

Lack of correlation between digit ratio (2D:4D) and Baron-Cohen’s “Reading the Mind in the Eyes” test, empathy, systemising, and autism-spectrum quotients in a general population sample

The second-to-fourth digit ratio (2D:4D) is sexually differentiated and is a likely biomarker for the organisational (permanent) effects of prenatal testosterone on the human brain. Recent research has highlighted a possible role of prenatal testosterone levels in both the etiology of autism-spectrum disorders and in sex and individual differences in cognitive styles of the normal mind (Baron-Cohen’s Extreme Male Brain Theory of Autism and Empathising/Systemising Theory). Importantly, autistic children present lower (hypermasculinised) 2D:4D than healthy controls. Based on these accounts, we investigated the relation of 2D:4D with Baron-Cohen’s measures of empathising (“Reading the Mind in the Eyes” test, RMET; Empathy Quotient, EQ), systemising (Systemising Quotient, SQ), and autistic-like traits (Autism-Spectrum Quotient, AQ) in the general population (N = 423 Austrian adults). Whereas sex differences into the expected direction and of expected size were obtained for all variables and internal scale consistencies tallied to retrievable reference values, 2D:4D was unrelated to RMET, EQ, SQ, and AQ scores. Candidate explanations for this lack of correlation might be possible developmental timing differences in the expression of 2D:4D and empathising/systemising, qualitative (as opposed to quantitative) functional differences between the normal and the autistic mind, or the suboptimal psychometric properties of the measures.
