A 2022 meta-analysis found that even small sex-based differences in general intelligence among school-aged children were an artifact of older tests, with current test batteries showing no statistically significant difference between the sexes, but that differences in intelligence sub-types such as processing speed (favoring females) and visual ...
The results found by the researches support the notion that gender differences in spatial abilities arose during human evolution such that both sexes cognitively and neurologically developed to behave adaptively. However, the effect of socialization and environment on the difference in spatial ability is still open for debate. [13]
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).
Sexual differentiation is the process of development of the sex differences between males and females from an undifferentiated zygote. [1] [2] Sex determination is often distinct from sex differentiation; sex determination is the designation for the development stage towards either male or female, while sex differentiation is the pathway towards the development of the phenotype.
The 21st century has witnessed a resurgence of research on gender differences in variability, with most of the emphasis on humans. The results vary based on the type of problem, but some recent studies have found that the variability hypothesis is true for parts of IQ tests, with more men falling at the extremes of the distribution.
FYI: The fluid (i.e. transformative) aspect of being gender-fluid can happen at any point in life. You can be super young or a supercentenarian—it doesn’t only occur during a particular time ...
A number of factors combine to influence the development of sex differences, including genetics and epigenetics; [5] differences in brain structure and function; [6] hormones, [7] and socialization. [3] [4] [8] [page needed] The formation of gender is controversial in many scientific fields, including psychology. Specifically, researchers and ...
However, they still found greater male spatial working memory in studies published in the journals Brain Cognition and Intelligence. [ 7 ] [ 8 ] Also, even though they found no sex differences in verbal working memory, researchers have found lower brain activity or thermodynamics in the prefrontal cortex of females which suggested greater ...
