Question

Quizplus · Accepted Answer

Studies have shown that after age 25, testosterone levels and rates of violent crime both decrease, indicating a relationship between hormones and aggression. However, none of the other options are supported by research. Hormonal influences are stronger in some animals than in others, but it is difficult to compare the strength of hormonal effects across species. Variations in testosterone do seem to be associated with differences in behavior, and higher levels of testosterone are generally associated with increased aggression, not decreased aggressiveness.
