Sex differences in verbal short-term memory have been found regardless of age even among adults, for example a review published in the journal Neuropsychologia which evaluated studies from 1990 to 2013 found greater female verbal memory from ages 11–89 years old. [2] [3]
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 ...
The same studied emphasized that adolescence is an important psychological development period; therefore, opinions formed about oneself during this time can have a significant impact on self-confidence and self-worth. [40] Consequently, low self-esteem can increase one's risk of developing an eating disorder, depression, and/or anxiety. [40]
[9] [8] Examples include greater male tendencies toward violence, [10] or greater female empathy. The terms "sex differences" and "gender differences" are sometimes used interchangeably; they can refer to differences in male and female behaviors as either biological ("sex differences") or environmental/cultural ("gender differences").
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 ...
However, the relationship between psychological maturity and age is a difficult one, and there has been much debate over methods of determining maturity, [40] considering its subjective nature, relativity to the current environment and/or other factors, and especially regarding social issues such as religion, politics, culture, laws, etc. [41]
The authors note that greater male variability is not ubiquitous, and ratios less than 1.0 have been reported in some national and international data sets. [10] A review by Hyde et al. (2009) also evaluated the topic of greater male variability in mathematics performance. [11]
Adult children can often be informal caregivers to their parents as they help them with personal needs, chores, and finances. [148] Marital satisfaction remains high in older couples, oftentimes increasing shortly after retirement. This can be attributed to increased maturity and reduced conflict within the relationship.
