But it was not a very happy childhood either. Alcoholism: Nature Versus Nurture For years people have argued that alcoholism is a choice and not a learned or inherited disease. Is it nature or nurture? There is , and it is more widely believed that this disorder is triggered by a complicated combination of factors including hormonal changes, genetics, environment, and brain chemistry. Temperament is a relatively stable feature of personality that emerges early in infancy, is surprisingly stable across the lifespan and is heavily influenced by genetic factors. While neither factor alone predicted depression, the boys with especially rejecting mothers, and a specific form of the dopamine transporter gene were at higher risk for major depression and suicidal ideation.
The way we are nurtured the environment in which we exist and learn must be the overriding factor. Nurture Throughout the history of human existence, there have always been questions that have plagued man for centuries. For the purpose of this paper, the development of depression will be researched in terms of the nature versus nurture debate. To solidify these mental illness predictions, the researchers observed the girls until age 18. On the first neuron, there is a serotonin reuptake transporter that sucks serotonin back into the first neuron to be recycled and used again. Twin Research and Human Genetics, 16 1 , 117-125.
Nature states people are born homosexual because of genetics. However, nativists also argue that maturation governs the emergence of , and even as a whole. And then, as I got older, my older brother was diagnosed with depression, and then my mum was diagnosed with depression, and then when I was about 18, I was diagnosed with depression. Thus, psychological traits follow a polygenic mode of inheritance as opposed to being determined by a single gene. This cohort of 1037 children was studied at ages 3, 5, 7, 9, 11, 13, 15, 18, and 21, and 96% of the subjects could still be found to answer questions at the age of 26. And that is the most liberating belief of all time.
Your genes make you more likely to suffer from clinical depression by determining your psychological and cognitive makeup This is maybe a little simplistic as ultimately the relationship between life events and depressive symptoms was shown to be complex and bi-directional. Characteristics and differences that are not observable at birth, but which emerge later in life, are regarded as the product of maturation. Just how much each factor contributes to that end product, however, is the detail that continues to be debated. He is a Fellow of the Faculty of Public Health. However, at times, it descends into a chronic state, or leaves behind some long-lasting effects.
The researchers found that the girls with depressed mothers had significantly shorter telomeres, while the girls with no maternal history of depression did not. Transmission of aggression through the imitation of aggressive models. While genetics cannot predict alcoholics very well, research can show that one can be born to be an alcoholic; the action and reaction taken in spite of or because of this gene however determines the outcome. Does that signify that we are genetically predisposed to mental illness, as implied by the nature argument? Nature and Nurture In practice, hardly anyone today accepts either of the extreme positions. Role of Mothers The role of the seems to be a large contributor to depression. For example, young children who are more fussy or have particular difficulty sleeping may elicit higher levels of frustration in responses by caregivers.
This is what lead me to the desire of what causes these behaviors; is it the product of nature or nurture? Ninety-seven healthy girls between the ages of 10 and 14 participated in the study; half of them had mothers with depression and the other half did not. Haeffel studied 177 male adolescents from a Russian juvenile detention facility. Depression is a good example of this process. Early negative interpersonal environments i. The black dog is a far more complex beast than that. At times alcohol abuse appears to be uncontrollable and most often. The 30% who do not respond may be due to their genetic makeup.
Studies suggest that the neurotransmitter dopamine may play a role in the risk for depression. Caspi and his crew collected information about previous depressive episodes, attempts, previous events employment, financial, housing, , and relationship stressors , and current psychological state. These events and behaviors can exacerbate mental illness that may have already been present, or they can mask the illness, making it harder to diagnose properly. This realization is especially important given the recent advances in genetics, such as polygenic testing. Three essays on the theory of sexuality.
This also happens to be the main spot where the most famous antidepressants, , such as Prozac, work. Gerald Haeffel of the University of Notre Dame and his colleagues, researchers wanted to see if a gene that controls dopamine interaction and maternal parenting style could predict depression. Another way of studying heredity is by comparing the behavior of twins, who can either be identical sharing the same genes or non-identical sharing 50% of genes. People select, modify and create environments correlated with their genetic disposition. I know that doesn't sound that exciting, but this paper manages to link nature, nurture, and in one elegant demonstration, and.
