These researchers study that relative effects of chemicals and hormones in determining aggressive behaviour. In regards to this, a series of research studies have examined the link between Monoamine Oxidase A (MAOA), serotonin and norepinephrine metabolizing enzyme, and aggressive behavior. In particular, Moffitt et al. (1998) reported that aggressive male have an average serotonin level that exceeds that of nonviolent male. In this case, MAOA deficiency…

argued that violent behavior in species just like other physical characteristics passed on to the future generations. How these traits passed on from primates to humans evolved violence. Another hypothesis is the warrior gene hypothesis, where Monoamine Oxidase A (MAOA) is considered a biological gene that causes the aggression and violence in the humans. Other factors that are highly evident for violence in primates and humans are the lack of resources, defense of land or sexual needs. How…

Major depression is a mood disorder that causes to have negative feelings for an extensive time as it could take a few days or even weeks. Those negative feelings include sadness, anger, loss, hopelessness and discouragement. They can interfere individual’s daily activities due to the lack of ambition and energy. Depression can be caused through different symptoms such as family history, stressful events, personality, loneliness, illness and physical changes. This essay will be exploring on…

Although there is no individual gene that has been identified in humans, a gene responsible for producing a protein called monoamine oxidase, this has been associated with aggressive behaviour. This causes serotonin levels to be low, and this leads to impulsive and aggressive behaviour. For example, in the 1980’s a Dutch family found that many of its male members behaved in a particularly…

Life with a psychological disorder, like depression, may be so hard to deal with that some individuals choose to end it. Suicide is considered as a tragic consequence of psychological disorders, most commonly depression and anxiety. Studies show that people who suffer from depression attempts suicide more than once. Although the cases of a person to have suicidal thoughts at some point of their life are not uncommon, and thinking about ending his/her own life is not necessarily abnormal,…

People wake everyday feeling severely sad. They want to die and are just waiting in anticipation for it to happen whether it comes naturally or by way of suicide. Some of these people could be loved ones to other people and these other people might have no idea that their loved one is suffering so deeply. This is a real disease and is not just a character of a person being weak and sad. This disease is called depression, which is feelings of severe hopelessness and sadness. Depression affects…

positively correlated with aggression if they had low cortisol levels (Mehta & Joseph, 2010). There are also studies that show that genes have a role in aggression. Caspi et al (2002) demonstrated that the gene responsible for encoding the enzyme Monoamine oxidase A (MAOA) could moderate the effects of childhood maltreatment, which often turns into aggression in adulthood. Individuals with low MAOA activity will show more violence. These studies therefore suggest that testosterone level,…

shows that some psychopathic behavior might indeed be found in genes. Studies have linked a “genetic variant called MAO-A, to psychopathy. MAO-A the so-called warrior gene containing distinct abnormalities in the X chromosome gene that produces monoamine oxidase A, an enzyme that influence the neurotransmitters dopamine, norepinephrine, and serotonin.” Thus, suggesting psychopaths are wired by nature to be the way they are. However, a vast amount of researchers believes that it is one’s…

For my discussion this week I decided to delve into extremism and the factors in personality that can turn strong differences in opinion to aggression and violence. The event that precipitated my interest in this subject is the recent rise of the IS in the Middle East. IS stands for Islamic State. The Islamic State has taken advantage of the ongoing Syrian civil war to stake a claim to land in both Syria and Iraq, proclaiming that they have formed a new caliphate. Of particular interest to me is…

The origin of a sociopath’s destructive path begins with a child with conduct disorder. To comprehend the reasoning behind the actions of a sociopath, one must understand what a sociopath is. Though a person can become a sociopath through heredity, it is possible to become one through a number of different environmental factors. There are several different environmental factors that could affect a child’s psychological state of mind including t. The setting where the child is living, or perhaps…
