If the role of biochemistry can be understood, it can then be treated and managed But it is unethical to give drugs to humans to alleviate aggression as it could lead to social control This could be treated more ethically through diet and exercise which acts on neural mechanisms. Genetics are involved in causing neural vulnerabilities to violence and aggression. Free and expert-verified textbook solutions. Biosocial Bases of Criminal Behavior.

Research shows a relationship between low levels of serotonin and violent behaviors, suggesting that a lack of serotonin is linked to aggression (Linnoila & Virkunen, 1992). This is important as many adoptees remain in contact with their biological families or are selectively placed in adoptive families that are similar to their biological ones.

But people were less angry if the bus had a sign saying out of service [Pastore 1952]. Christiansen (1977) found MZ concordance rates of 35 per cent, compared with 13 per cent for DZ twins. Children learn aggressive behaviors through observing aggressive models. Creatures have evolved an instinctive response to certain signs. Cognitive priming is based on the idea that memory works through association. This could be more effective in certain types of people [not very intelligent, have no positive role model, feel hard done by in life].
