Kersey, A.J., Csumitta, K.D. & Cantlon, J.F. Gender similarities in the brain during mathematics development. npj Sci. Learn. 4, 19 (2019)>We measured 3–10-year-old children’s neural development with functional magnetic resonance imaging (fMRI) during naturalistic viewing of mathematics education videos. We implemented both frequentist and Bayesian analyses that quantify gender similarities and differences in neural processes. >Across all analyses girls and boys showed significant gender similarities in neural functioning, indicating that boys and girls engage the same neural system during mathematics development.
So apparently, looking at fMRI, you can't distinguish males from females while they are learning math.
Can someone with a good understanding of the subject explain if there's anything misleading about this study?
