Growth And Development Of Personality Psychology

As humans, we are social beings. However, some of us are more social than others. Research shows that temperament does seem to be related to genetics, but to what degree? Kagan (2008) argues that children are born with a physiology that makes them biased toward a particular type of temperament (Shriner B., & Shriner M., (2014). An example of some being more social than others, me and my oldest son are very sociable people, while my youngest and my husband are not as sociable.

Many of our personality traits are developed by the interactions that we have had with others during our informative years. Our behavior is a reflection of our own personality and there is considerable evidence to show that personality can be inherited. Genetics are particular molecular structures of genes, as it is explained through science the effect that these genes have on our behavior and our body’s actions throughout our lives. Both the Endocrine System and Heredity have a large influence on human behavior. They determine our moods, irritability, and even our level of energy, even though the environment still plays a huge role. These personality genes, work by changing the structure of neurotransmitters, or receptors or emitters in the brain, which affects how our brain cells communicate with each other.

Who a person’s parents or relatives are is already predetermined at conception. The traits that a child’s family have are going to be his/her traits simply because of genetics. According to the above study done on Croatian twins, genetic factors account for “stability in personality” from seventy-five to one hundred percent (Bratko and Butkovic 155). The researchers used genetic models to look into the differences between twins. They broke genetics into two sources in this study: additive genetic influences and nonadditive genetic influences. Bratko and Butkovic insinuated that, based on the findings of this project, heredity was mostly attributed to the steadiness of personality in the pairs of twins. In the novel Nature Via Nurture: Genes, Experience, & What Makes Us Human by Matt Ridley, a quote was attributed to Ralph Greenspan from his research on romance between fruit flies. He likened personality to this

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.

A person’s nature, or genetics, determines aspects of the psychology of a person before they’ve been born. There are many example of how genetics determine characteristics of a person, regardless of the environment, also known as

Personality may be based on many factors. It may be based on innate or learned experience, or latent or manifest. But, the focus of this essay will be whether a person's personality is based on the magnitude of genetic or an environmental influence. Personality can be divided into two categories, innate or acquired characteristics. Heritability is a statistical measure that expresses the proportion of the observed variability in a trait that is a direct result of genetic variability. Environmental influences can be divided into two classes, shared and non-shared environment. Both heredity and environment contribute to personality traits and that the degree of their individual contributions cannot be specified for any traits. Although a person's environment plays an important part in their personality development, heredity factors play a larger role in deciding disposition of this

Plomin’s interest in evolution, natural selection, and genes began at a young age. He studied psychology and completed his dissertation on the topic of temperament and personality development, under the direction of Arnold Buss at the University of Texas, Austin (Pearce, 2003). For his study, parents of 137 sets of twins between the ages of two and six were asked to rate the temperaments of their children, as well as report the temperaments of themselves and their spouse. The results demonstrated great genetic influence on the characteristics of impulsivity, sociability, emotionality, and activity level, which are all important aspects of temperament (Pearce, 2003).

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 nature vs. nurture debate is one that has persisted throughout generations of scientists and neuroscientists. Some believe that all aspects of human behavior and human functioning are strictly hereditary, passed down from the parents through genetics. Others believe that the environment has a much greater impact, and can determine one’s personality and intelligence. However, this issue is not as black and white as it might appear. While genetics might have more power than the environment, it is my belief that both are equally important in the shaping of one’s personality and behavior.

Of note in the debate between nature and nurture in personality development is a study conducted by Dr. Fatima Kamran (2016) regarding perceived personality differences between siblings by parents. This was a very important study in regards to nature versus nurture, since both lines of thought would suggest that siblings that share genetics and home environments would be similar to each other. In this study, parents of siblings with an age difference of no more than five years, were studied to determine if they perceived differences in their children’s temperaments (Kamran, 2016). Despite behavioral genetic

The roles of heredity, environment and epigenetics all aid in creating people, yet they are the reason why everyone is different. In this section, heredity, the environment and epigenetics will be discussed about their importance. Heredity is the genetic makeup the represents every individual. Heredity has been shown to “account for 50% of the variance in personality” (Lecci, 2015, sec. 4.6). Heredity might affect personality disorders, considering that “genetic…contributions to…borderline personality traits and substance use…accounted for all the associations…” (Few, Grant, Trull, Statham, Martin, Lynskey, & Agrawal, 2014, p. 2119). Heredity plays a part in the development of personality, because a person’s level of stress will contrast to

Both nature and nurture interplay to determine personality characteristics. Nature is heredity and passed on at conception. Nurture is that which is environmentally developed. It is innate that a baby will crawl, but he needs the support of his environment (diet, etc.) if he is to ultimately survive. Our behaviour is the result of a combination of inborn traits and the situations in which we find ourselves. There are five categorise which help influence personality differences. Genetically, offspring tend to take on some of the characteristics of their parents. However, this could be due to long term exposure to the personalities of their parents rather than their genetic coding. Whether a person is male or female determines what gender role they take on. ‘Women are expected to be nurturing, attractive, emotional, weak, and subordinate to men; whereas, men are the strong, rational, objective, and financial providers’ (Loue and Sajatovic, 2007). Ones family experiences can also influence a person’s behaviour. Family experiences like: ‘family size, birth order, differential parental orientations towards children’ etc. will impact on the emergence of personality as well as a person’s suitability to leadership roles (Morley and Moore et al., 2004, pp. 28-52). Culture plays a very strong role in determining what is believed to be acceptable and unacceptable

The world of Genetics is one that is both fascinating and interesting. When tackling how genetics plays a role in behavior, one must look within the scope of what genetics is before dealing with how it plays a significant role in one’s behavior. Simply put, genetics is the study of genes. It is a biological component within the entire study of biology itself. Scientists who study genetics and perform research do so with the intent to learn more about how genetics affects the overall attitudes, behaviors and dispositions of individuals. It could be said that genetics is somewhat of a psychological-biological science as researchers look at the underlying patterns within the genes that cause

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.

Human character and behaviour are not only shaped by the genes that encompass the individual’s genotype. Human character comprising mainly of personality, sexuality, morality and intelligence are the products of genetic determinism as well as external environmental factors. “Single genes can have surprisingly strong influences on particular aspects of behaviour.” (Frank., 2009)
