Verified step by step guidance

Step 1: Begin by understanding the context of the question. It asks for a biochemical influence on aggression, which means we need to focus on factors that are directly related to biological and chemical processes in the body.

Step 2: Review the options provided. Parental discipline style, exposure to violent media, and societal norms regarding conflict are all environmental or social factors, not biochemical influences.

Step 3: Recall that testosterone is a hormone produced in the body, primarily in the testes in males and in smaller amounts in the ovaries in females. It is a biochemical substance that has been linked to aggression in various studies.

Step 4: Understand the mechanism: Elevated levels of testosterone can influence aggression by acting on the brain, particularly areas like the amygdala and prefrontal cortex, which are involved in emotional regulation and decision-making.

Step 5: Conclude that the correct answer is 'Elevated levels of testosterone,' as it directly represents a biochemical influence on aggression, unlike the other options which are social or environmental factors.
