Effect of Heredity and Environment on the Development of Personality

Identical twins are many times seen as genetic reproductions representing variations from twin to the other twin and are created because of environmental factors (Cervone & Pervin, 2010). Since identical twins share identical genetics, his or her personality seems to also share similarities. Moreover, the environment can impact fraternal twins, resulting in fraternal twins personalities and his or her characteristics similar to each other. For example, identical twins. Some research shows twins that are raised in the same residence have little differences from those who are raised in a different home.

The nature vs nurture issue has been a controversial argument among psychologist for decades. This argument exposes two different views. One of them emphasizes that our personality depends solely on genetics (nature). On the other hand, the second view suggests that humans “develop through experience” (Myers 2013, SG 6) (nurture).

The article was written by Sharon Begley, who is a science writer. It published on December 1, 2008, and it has been illustrated by Harry Campbell for Newsweek. We always think our personality is related to our genes, which is stable or cannot be changed. However, Begley assume we can change our personality as we grow up. It depends on environment and our parents. They both play a great role in shaping our personality.

Theoretical Propositions: The question of why people are who they are and why they behave the in the way that they do was asked. The researchers wanted to understand if people develop into who they are primarily from factors in the environment or because of there genetic makeup. In the second half of the 20th century most psychologists agreed in the theory of behaviorism, human behavior is caused only by factors in the environment. This study would answer the common “nurture vs nature” question that many people still ask today.

As many people have begun to pay attention to formation of personality, the debate over nature vs. nurture has raged for a long time and this issue is still controversial. However, as shown the

Have you ever noticed that you might act like your parents? Or maybe that your personality has changed over your lifetime? People have been debating about the nature versus nurture debate for a long time, and some think nature or genetics plays the bigger role in shaping personality, but some say nurture or society does. Nature and nurture both play a big part in determining what our personality will be. Identical twins have many differences. Your personality can change through your life because of the way you were raised. Studies show that nurture is much more dominant than nature is. Nurture is much more dominant in shaping personality than nature.

The basis upon which behavior is determined and influenced is widely disagreed upon. Among some circles, it is believed that if behavior is determined by the biological process, then there is no basis for morality because an individuals behavior is a product of genetics. Others disagree, and suggest that behavior is determined entirely by nurture rather than nature. To properly understand how behavior is determined, the role of environment, genetics and biological processes in behavior, and the basis for morality, must be understood.

An age-long research topic in Psychology has been the issue of nature versus nurture issue. Nature versus nurture refers to the extent to which an individual’s genetics (inherited traits) or immediate society affects his or her personal growth. A very vivid example of the role nature or nurture plays in determining will be my personality. For example, my father and mother have mild temperaments, so I was raised in a somewhat conservative home. In my case, pro-nature supporters argue that my genetic makeup will largely determine the personality traits I develop. In this case, if I inherited a mild temperament, then I will most likely reflect such personality traits. Nurture supporters on the other hand,

On the other hand, there are people arguing that our personalities our moulded purely by external factors such as family, friends, teachers, and society as a whole (Spaulding, 2009). What is certain is that our heredity and DNA can carry traits which make us susceptible to mental disorders and psychopathology, which can have serious affects on personality (Spaulding, 2009). For instance, Down syndrome children have difficulty in communicating and understanding thus, causing them to be slow learners and anti-socialites. A person with a hypothalamus lesion may experience obesity or underweight that is beyond his or her control. However, the aspect of environmental influence (nurture) should not be entirely excluded. For instance, a person who has two obese parents can grow to be healthy and slender as healthy food is available for him or her.

Have you ever wondered why you are what you are? An old debate has been going on about weather your personality is affected by nature, your genes, or nurture, the way you were raised. Both nature and nurture play a part in your personality. Identical twin’s personality can be different from each other. My personality has changed from when I was born. Studies have proven the nurture is more effective. Nurture plays a bigger part in personality than nature.

The general conclusion emerging from heritability studies is the inconsistencies in almost every human characteristic—including inclination and social behaviors—is shaped significantly by genetic influences (Plomin et al., 2012; Turkheimer, 2000). For example, studies have shown substantial heritability usually around 50 percent or more of everything from the fact of how much time a person spends watching tv (Plomin et al., 1990), breastfeeding (Colodro-Conde,Sanchez-Romera, and Ordonana, 2013), and breakfast eating patterns (Keski-Rahkonenet al., 2004) to political ideology and party affiliation (Alford, Funk, and Hibbing, 2005)

The topic of research was Biological Influences on Personality: Temperament. Personality is not just something we learn, there are also biological influences that help shape a person’s personality. Our book refers to temperament as biologically based emotional and behavioral tendencies that are evident in early childhood (Cervone D., & Pervin, 2015 p.488). Each article provided an insight on how biology plays an important role in our personality/temperament.

There is evidence to belief that personality and biological matters tend to coincide with each other in certain instances. However,

Nature combines with nurture to form our personalities. Our genes may predispose us for certain inheritable traits such as diseases like cystic fibrosis or even just irritability, similar to our relatives, but the environment we are raised in has quite a bit to do with how visible certain aspects of our personality become. If a child is always around an environment where there is constant arguing and yelling going on, the child may naturally feel that is the proper thing to do when things do not go as they would like. Likewise, genetics play a role in determining a person's body type, thus you could get your eye color from your mom, and your height from your dad.

Life events might have the greatest effect on how our personality shapes up, the argument of nature – nurture might also come to have an impact on how we respond to events that shape our personality. Some people might have grown in a more peaceful environment but might come to find their temperaments are not friendly, on the
