Agreeing with these authors argument, I too believe that violence in human beings is biological. According to Dale and Richard, there are a few well-known painters, authors and anthropologists believed that “human evil was a naturally acquired thing.” This means
Low activity of the orbital cortex means less normal suppression of behaviors such as rage, violence, eating, sex and drinking. In addition to brain scans, Fallon also tested DNA of his family for genes associated with violence. He focused on the MAO-A gene, short for Monoamine Oxidase A, also known as, the “warrior gene.” This gene regulates serotonin into the brain. Serotonin
Our society is responsible for aggression. Many people argue that aggressive people were born with a predisposition to perform violent acts, but that does not settle with many psychologists’ studies. Other people believe that violent people were made from exposure to aggression during childhood. Both of these perspectives represent points of a larger argument started by Francis Galton 150 years ago most commonly known as “Nature versus Nurture”. After 150 years, and the founding of a new branch of science, epigenetics, scientists now have viable proof that that nurture is more influential in the case of aggression because epigenetics show that environments are responsible for gene expression.
This gene is most commonly harmless, although if one has a mutation in this gene and is abused or mistreated as a child, they are at risk of becoming dangerous. Many factors go into gene expression. Environmental factors can range from the food one consumes to how one manages their thoughts. Past backgrounds, like childhood and recent experiences, have a part in aggression caused by the mutated gene. The MAOA gene mutation is most common among men.
nurture argument comes up. I do not think the primary cause of violence is biological or genetic, and I believe the vast majority of males do not commit violent acts because they are capable of controlling their base instincts. Men are not violent beasts, or at the very least, most of them are not. As far as I know, nearly everyone gets violent and intrusive thoughts once in awhile, but most people can control them, they do not act upon those thoughts. This is what separates us from the psychopaths and murderers.
Violence is often a result of growing up with negative influences or no fatherly
According to Freudian psychoanalysis “repression of the instinctual id leads to the psychopathology of everyday life, which in turn makes violent behavior commonplace.” ( Jennifer McClinton-Temple1, 18). Likewise, Herbert Marcuse in his book Eros and Civilization (1955) attempted to fuse Freudian and Marxist theories to undercut the cultural codes that over determine and repress human psychology and sexuality, resulting in deviant tendencies. The complexity of human violence has been studied in modern Psychiatry. James Gilligan in his 1996 book, Violence: Reflections on a National Epidemic, offers a theory on the origin of violent behavior.
B.F Skinner the behavioral psychologist said that “no theory changes, what it is a theory about. Man remains what he has always been”. What Skinner means that we as humans we develop these feelings of aggression or acting violent through things we experience throughout our lifetime. To a full extent humans are naturally violent, due to the idea of that we have aggression and violence embedded in us an
1. Some of the biggest supporting research for the idea of the “criminal gene” comes from the work of neurobiologist Dr. James Fallon. Dr. Fallon is the head of the anatomy and neurobiology school of medicine at UC Irvine. His research suggests that there is a group of genes common in some people that make them much more prone to violence. He calls these the “warrior genes.”
Genetic differences also can impact on aggressiveness. Differences in temperament can be observed shortly after birth, even among siblings in the same family. These traits may endure into adulthood (DiLalla & Gottesman, 1991). The theory that aggression stems from frustration, suggests that, aggression stems from frustration resulting from a person experiencing a blockage or interference in attaining a goal.
One of the scientists in that area, Albert Bandura claims that individuals are not born to act violently, but rather they learn that behavior later in life, through family interaction, environmental experiences, and mass
In 1993 scientists reported a Dutch family, there were 14 members of the family and all of them were sociopaths. They entire Dutch family had a mutation in a gene that makes an enzyme called MAOA. The enzyme’s function is to break down neurotransmitters like serotonin, norepinephrine, and dopamine. Over production of testosterone might be a factor that creates mass shooters. Normal testosterone levels are between 20%-200% of the average, and people whose testosterone levels exceed 400%, are more prone to violent behavior and over aggression.
Adrian Raine, criminologist and author of "The Anatomy of Violence: The Biological Roots of Crime," has said before, is a very important factor in criminal behaviour that affects about 75% of a person’s criminal activity. In his book, Raine explores the many evidences that lead up to biological and genetic influences on crime

The topic of this assignment is to discuss and analyse what factors affect human behavior and in doing so how human behavior is shaped. But before discussing that, it is important to understand what human behavior is. To define it in a few sentences or words would not be sufficient as human behavior consists of many factors and therefore contributes majorly to who we are as a person. But to put it simply, it is defined as all actions and emotions that an individual portrays in response to the different kinds of stimuli they receive no matter whether these responses are conscious or subconscious and voluntary or involuntary (Merriam-webster.com, 2015).
