The pelvis is, in general, different between the human female and male skeleton. [12] [13] Although variations exist and there may be a degree of overlap between typically male or female traits, [12] [13] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex ...
One line of inquiry has focused on the role that stereotype threat might play in mathematics performance differences between male and female test-takers. [27] Systematic reviews and meta-analyses suggest that stereotype threat is implicated in performance differences on some mathematics tests, though the effect appears to vary considerably in ...
Structurally, adult male brains are on average 11–12% heavier and 10% bigger than female brains. [21] Though statistically there are sex differences in white matter and gray matter percentage, this ratio is directly related to brain size, and some [ 22 ] argue these sex differences in gray and white matter percentage are caused by the average ...
In 2014, a meta-analysis of 215 study sample by researcher A.E. Johnson and D Voyeur in the journal Cognition and Emotion found overall female advantage in emotional recognition. [ 4 ] Two 2015 reviews published in the journal Emotion review also found that adult women are more emotionally expressive, [ 17 ] [ 18 ] but that the size of this ...
This research found virtually no difference in the variability of male and female infants birth weight, and it was concluded that if variability favoured any sex it was the female sex. [ 5 ] [ 6 ] [ 9 ] [ 10 ] The general consensus today is that boys have a higher birth weight than girls, and are more responsive to their mother's diet while in ...
In the absence of a Y chromosome, the fetus will undergo female development. This is because of the presence of the sex-determining region of the Y chromosome, also known as the SRY gene. [5] Thus, male mammals typically have an X and a Y chromosome (XY), while female mammals typically have two X chromosomes (XX).
