TESTOSTERONE INCREASES IMPULSIVE BEHAVIOUR IN MEN, SUGGESTS A STUDY
The male hormone testosterone is important for sexual and reproductive development but it can also make men less likely to question their impulses, suggests new research.
Men given doses of testosterone performed more poorly on a test designed to measure cognitive reflection than a group given a placebo, showed the findings of a study. The findings suggest that the sex hormone is connected with greater reliance on gut instincts and less self-reflection. “What we found was the testosterone group was quicker to make snap judgments on brain teasers where your initial guess is usually wrong,” said Colin Camerer, Professor at California Institute of Technology in the US.
The study included 243 males who were randomly selected to receive a dose of testosterone gel or placebo gel before taking a cognitive reflection test.
