Question

As discussed in the textbook, a psychology study conducted in the 1970s compared men raised in the northern part of the United States to men raised in the South. When a confederate in the study was verbally aggressive, southern men responded by
exhibiting increases in cortisol and testosterone

Answer 1

In the above study it was found that  verbally aggressive, southern men responded by exhibiting increases in cortisol and testosterone.

According to the findings, cortisol in 113 late-adolescent male offenders attenuated the relationship between testosterone and violent crime. Particularly, only those with somewhat low basal cortisol concentrations showed a strong correlation between basal testosterone and violent conduct.

An increase in cortisol is associated with an increase in aggressive behavior, whereas an increase in estradiol is associated with a decrease in aggressive behavior. While cortisol and serotonin work against testosterone to counteract its effects, testosterone triggers the subcortical regions of the brain to cause aggression.
