Phelps and colleagues (1997) help define monozygotic (MZ) as one sperm fertilizing one egg and dizygotic (DZ) as two individual sperms fertilizing two separate eggs. This is important to understand because this paper will primarily focus on the studies surrounding the onset of schizophrenia in MZ twins. Twins are such a unique source to study and observe because they convey how much of a person’s personality is because of family environments and how much is from a person’s genetic make-up (Kato & Pederson, 2005). Most commonly referred to as the battle between nature and nurture. Most differences that appear between MZ twins are due to experiences that one twin will experience that the other twin will not (Kato & Pederson, 2005). Crawford and colleagues (2007) note that this is how types of attachment can easily be recorded. Attachment styles (Crawford et al., 2007) help understand how exactly social relationships in varying life domains are created, preserved and dismissed as adults. By identifying these forms of attachments in early childhood, mental health professionals can begin recognizing symptoms for schizophrenia (Heiden & Hafner, 2000). By using identical twins, we can further investigate whether a parent’s use of a secure or avoidant attachment will develop a specific personality trait within their child that can possibly lead to schizophrenia.
Understanding Schizophrenia Schizophrenia is a severe cognitive impairment that interferes with a person’s mental or
1. Some people have argued that the Johns Hopkins psychologist used this opportunity as an experiment to test his nurture theory of gender identity. What are the expected results of this experiment, assuming that the nurture theory is valid?
Nature or Nurture. Nature may be all of the genes and hereditary factors with which influence them to become who they are such as physical appearances and personality characteristics. Nurturing impacts people’s lives as well as how they are raised and all the environmental factors. In combination, these qualities can be the true identity of oneself. Many people may argue that nurture appears to a play huge factor in the two, but others may think otherwise. Not having both as a characteristic can have a negative effect on a person physically and mentally. The debate of nature versus nurture appears to be the oldest argument known to man, and it still remains to be unanswered. In the old-age argument nature versus nurture, nature may play a huge role in determining a person’s true identity.
The concepts of Nature vs Nurture, are major concepts in social science. Nature is the hereditary pattern of physical features in a human being 's development. These features include, but are not limited to, our personality, usual and unusual appearances and the general measurements of how humans hold the attributes of being sociable, hostile behavior, their emotions, and the usage of alcohol and drugs. On the other hand Nurture is slightly different. Nurture is the influence of the environment that plays upon the behavior and characteristics in a human. The idea of nurture is that humans will grow up to form their personality on the way they are raised and life experiences. Culture is defined by the people in the environment, however, the environment helps shape and form human personalities in order to forge a culture. Culture is created by religions/beliefs, clothing/foods, language/social habits as well as the humanistic discipline; such as music, paintings, literature, and many more. Culture is generated by humankind, because humans hold their belief systems and patterns that was passed down by generations; by humans passing down what they have learned from their families this begins to create a culture. Personality plays a central role in both nature vs nurture and culture. Furthermore, personality is stated “the total organization of inherited and acquired characteristics of an individual as evidenced by the individual 's behavior (Hunt 119). Personality is either
Erickson’s psychosocial theory adds perspective to why identical twins, Linda and Lydia, turned out differently (Feldman 2010). Linda was raised by a family in the rural west, while Lydia went to a family in the urban south. These are two very different situations filled with different socioeconomical environments (Feldman 2010). The differences in the girls’ social environment could have had huge influence on their cognitive development (Feldman 2010). We need to analyze what Erickson’s psychosocial theory says about the way our social interactions with other people can test and outline our development (Feldman 2010). We can also take a look at the
Susan Evers and Sharon McKendrick, the famous identical twins from the movie The Parent Trap, were separated at a young age by their divorcing parents. Sharon grew up in Boston to a socialite mother while Susan grew up in California on her father’s ranch. Sharon had structure while Susan’s life was very laid back. They looked the same and liked many of the same things, yet their personalities were very different. What is responsible for these differences? Is it simply that they are two different people with different interests and preferences? Or did the environments that they grew up in play a part in making who they are? In the nature vs. nurture controversy, nature proclaims that our genetic make-up plays the primary role in human
The nature side of the argument is basically what we are born with, our heredity. The main idea of this is that we are born with predetermined traits that may or may not create psychopathic tendencies in us. Dr. Richard Davidson of the University of Wisconsin at Madison published a report in 2000 that compared brain scans of five
Nature versus nurture is a complicated subject to speak about. If one’s abilities or lack of are due to their environment or their genes. For example, a child is behaving negatively in class. Many individuals are quick to jump to the conclusion that “Oh, that kid’s parents don’t care, or just don’t know how to raise their child.” That could very well be a possibility, but most people never think that maybe they have a hereditary problem, such as ADHD, that was passed on to the child. This cannot be helped by the child, it is out of their control, but can be just as easily overcame than to just using their disorder or disability as a crutch. It is a very controversial topic in terms of which one is more important. Does the disorder or disability completely ruin the person’s life or can they overcome it? Which has the most effect on one’s life? The answer is, yes.
“Money Changes the Way We Think” and “The Science of Success,” both explore the topic of nature and nurture. Nature is usualy seen as the beter gene to have since it gives you a ‘fight or flight’ instinct. While it's counterpart Nurture is seen as the weaker and less prefered gene to have since it's typically seen as a handicap. While these two might have some similarities, it's their differences that truly defines them.
Does the environment that one grows up in contribute to alcoholism or is alcoholism determined by genetics? It wasn’t until 1991 that alcoholism was considered both a medical and psychiatric disease by the American Medical Association. Alcoholism is defined in the dictionary as a chronic disorder characterized by dependence on alcohol, repeated excessive use of alcoholic beverages, the development of withdrawal symptoms on reducing or ceasing intake, morbidity that may include cirrhosis of the liver, and decreased ability to function socially and vocationally. (dictionary.com). It is also defined as an addiction to the consumption of alcoholic liquor or the mental illness
In society, not one person is alike. By saying this, many people believe that they strongly take after their parents. Meaning they think Nature is a big part in their life and why they are who they are. The genes in each cell in us humans determine the different traits that we have, more dominantly on the physical connections like eye color, hair color, ear size, height, and other traits. However, it is still not known whether the more abstract attributes like personality, intelligence, sexual orientation, likes and dislikes are gene-coded in our DNA. The nurture theory has experiments showing a child’s behavior with the environment as to adult behavior. In the Nature Vs Nurture debate, everyone has their own thoughts and ideas on each
Growing up was an interesting time for me. I believe that both nature and nurture played a role in my development growing up. Nature is the influence genetic has on development. Nurture is the influence the environment around us has on our development (Levine & Munsch). The reason I think nature played a big role for me growing up is because in a lot of ways, I acted as my mother did.
The Nature vs. Nurture has been a long never ending debate for some time now. Nature vs Nurture has been so profoundly debated, that now it’s unclear whether what makes us who we are and what we do, nature or nurture. For purposes of this essay Nature is going to be defined as characteristics we acquire through our genetic and biological factors, while that Nurture is going to be defined characteristics we acquire through our interactions and influences with the environment. There are endless ways of taking an approach to the Nature vs Nurture conflict, thus the reason that it’s truly unclear if its Nature or Nurture or even both what makes us who and what we are.
Aim: The aim of this experiment was to explore the synergistic effects of heritability and environment in the cases of two brothers with schizophrenia.
The way you look and you physical feature all thing that we get from your parents , things like your eyes and hair colors are things that we in……. from our parents . However talents and personality do not come from your mother or father it come from that environment . a place where you grews up has a big affect on how you talk and how you react or respond things around them.The nature and nurture debate is hard to choose if a person development is influenced by the DNA or is it influenced by life experiences and the environment. Both nature and nurture have a big role on how children develop.
Within twins, monozygotic twins have a 48% probability if their twin is diagnosed with schizophrenia, and with dizygotic twins it is a 17% probability (Kalat, 2015). This shows that there is a genetic bases for schizophrenia, it also highlights that other non-genetic factors must play a role in the development of the disorder. These results have been backed by many research carried out on adoption studies. An adoption study in Finland carried out aimed to test the hypostasis that family rearing plays a factor in the development of schizophrenia (Tienari et al, 2004).Their research found that adoptees at high genetic risk (biological mother had schizophrenia) were more sensitive to problems in the adoptive family environment. Adoptees with high risk and a severally dysfunctional family rearing were significantly coordinated with a diagnosis of a schizophrenia spectrum disorder (Tienari et al, 2004). In support of the diathesis model neither high risk nor dysfunctional rearing were significantly linked with a diagnosis (Tienari et al, 2004). The research found that a ‘healthy’ adoptive family, acted as a ‘protective effect’ for the adoptees with
