Aggression Is a Part of Human Nature
Aggression Is a Part of Human Nature

Aggression is something that you see everyday from turning on the television to watch the daily news to playing one of your favorite video games. This is something that is a part of human nature and will always be a part of our social life. There are many influences in our society and within us that can make aggression arise more frequently. These are genetic influences, neural influences, and biochemical influences.
Some influences on aggression are believed to have been passed down from generations (Myers, 749). This is believed to make an effect on future generations, therefore, inheriting certain traits, one of which could be having a bad temper. For example, when we look at animals to refer to this concept many think of canines that have been specifically bred to be aggressive. Is it possible that over many years of training an animal to act this way that this trait will continue on for generations to come?
Neural influences suggest that brains have systems that when they are triggered, can produce aggressive behavior. There is not a specific area in the brain that controls aggression (Myers, 750). There is a neural system that when provoked, it will create aggression. It is believed if this system, located at the frontal lobe, is damaged it could make aggression more likely.
Recently, a study has been determining that aggression can weaken the brain’s impulse control circuits (Asher). The enzyme monoamine oxidase-A, or MAO-A, which is responsible for breaking down mood-regulating chemical messengers, is one of the chemicals that could be responsible. The study contained of ninety-seven subjects and the area that was responsible for impulses and motivations was affected by fourteen percent.
It is believed that some substances in the blood could possibly trigger aggression. Substances like hormones, alcohol, and testosterone are said to be some of the major causes. Men with lower levels of testosterone are less

    The two neurotransmitters that are believed to be the most associated with aggression are low levels of serotonin and high levels of dopamine. These two chemicals allow impulses to be transmitted to another area; therefore all behaviours are influenced by neurotransmitters. There is also the influence of the amygdala, which controls the emotional responses, the hypothalamus, which coordinates both the autonomic nervous system and the activity of the pituitary and the frontal cortex.…

    The instinct theory of aggression states that aggression is natural and involves innate tendencies that are stable and enduring, meaning they are difficult to modify. It proposes the idea that aggression is a result of survival instinct to protect or survive. Aggression is said to occur in high arousal situations where stressful cues act as triggers for that aggression, often caused by others as a result of retaliation. However, not all people show aggression as a result of high arousal or stressful cues, so this theory lacks some validity when explaining aggression. Also, aggression is shown by different…

    Another theory behind aggression is sexual selection, because in some cultures there are fewer females than males. In order for males to attract a female they must compete with each other, and one of the ways they do this is by taking part in war. Male warriors in traditional societies tend to have more sexual…

    A gene called MAOA is associated with aggressive behaviour, it regulated the metabolism of serotonin, and additionally low levels of serotonin are associated with aggressive and impulsive behaviour. A study from a Dutch family with a history of violence including rape and arson found low levels of MAOA in their blood. It showed that the men had a defect in their MAOA. This study shows that the gene MAOA is associated with aggression, this means that some genes can influence the susceptibility to aggressive behaviour, however it is not certain that one gene can determine aggressive behaviour, however it is likely that many genes can contribute to human behaviour rather than one single gene.…

    The function and structure of the brain has long been implicated in the explanation of violent behaviour. From cases studies as early as 1848, in which head injuries resulted in changes of personality and behaviour. The prefrontal cortex was identified as a region of interest as specific head wounds to this area resulted in increased aggression and violence. The improvement of neuropsychological testing and brain imaging has further described the role the prefrontal cortex plays. Current theory and research indicates that the amygdalo-hippocampal complex (AHC) is implicated in the control of aggression and that the prefrontal cortex regulates…

    There are several foundational theories that are under-pinning’s for treatment and services. The Biological Theory says that violent behavior is biological and organic. This means that the violent behavior can be explained by genetics, biochemistry, and changes in brain development because of trauma that may have occurred (Jaffe & Wolfe, 1999). It is believed that certain abusers may suffer from head injuries which may have affected their ability to solve problems and act on their ability to perform self-control.…

    Further research has been conducted to expand on the impulsive and aggressive behaviour displayed by criminals to determine whether there is a biological or chemical explanation. Serotonin is a chemical in the brain that plays an important role in the personality traits of depression, anxiety, and bipolar disorder. It has also been shown to be involved with brain development. A lack of Serotonin has been found to be associated with impulsive behaviour and emotional aggression in individuals. Dopamine, a transmitter in the brain that is…

    It is claimed low levels of serotonin, reduces the ability to control aggressive impulses. Proof of the role of low levels of serotonin in aggression comes from Mann, who manipulated levels of serotonin. They directed the drug dexfenfluramine known to reduce serotonin levels, to 35 healthy adults. They then used a questionnaire to assess aggression levels, and found these levels had increased among males after treatment with the drug.…

    According to many social psychologists, there are only three ideas associated with aggression. There are biological influences, frustration and learned behavior. Many may presume there are more weaknesses or strengths in these particular perspectives. Although, many meaningful debates have been researched on whether or not aggression is human nature or social…
