Biological differences between the sexes have been identified at all stages of the study of German scientists.
Scientists from the University Hospital of Tubingen (Germany) analyzed the sex differences in response to a stressful situation. Firstly, the subjects performed the calculation of certain tasks. They also play a virtual football, during which studied the impact factor of social exclusion. When filling out the questionnaire in the subjects was determined by self-assessment.
Men and women performed equally exhausting task, however, the level of the stress hormone cortisol increased only in men but not in women. In response to the increase in cortisol in men activated areas of the brain responsible for attention, whereas they remained unactivated women.
When social stress in women increased levels of the hormone progesterone, and men - testosterone. Since progesterone is essential for belonging to a particular group, the researchers found increase in its expression of uncertainty in women.
As it turned out, an important role in combating stress self-esteem plays differently manifested in subjects of different sexes. Less self-confident women showed activity in the cognitive areas of the brain, that is, they have been focused primarily on the task. Men, by contrast, activated areas associated with emotions and self-esteem.
Individual experiencing stress also found gender differences. When performing tasks on social performance assessment in women noted a subjective response in comparison with men. Women can control their emotions worse.
