Recommended: Biological influences on personality
“Why are you so quiet?”, “You should get out more”, “You can talk?” As these questions repeatedly bleed into the ears of those who choose solitude over socializing, silence over noise, the world keeps talking. In a society full of social standards, we strive for the idea of perfection. Being so encaptured with this idea, we sometimes forget that perfection, being merely subjective, is a fictitious idea implemented in our minds in order for society to thrive off of our arduous efforts to achieve it. One of such ideals society often tells us to strive for is the perfect personality: one who is sociable, friendly, and charismatic, or to put in one word, extroverted. The American society cradles extraversion but dismisses those who are introverted. …show more content…
What exactly is the definition of introversion? Although there have been various interpretations of Carl Jung’s first research into introversion, most people have come to a general consensus that it is a personality type characterized by the preoccupation in one’s inner self. Arnold Henjum, professor at the University of Minnesota, commented on how an introvert focuses more on the thoughts and feelings of the moment rather than the “object” of the encounter (Henjum 40). When one first hears the word introvert, the first associations made are usually shy, quiet, and antisocial. While those can be traits of an introvert, it should not be assumed that it is that simple. Introverts, as opposed to extroverts, gain their energy from themselves through …show more content…
Studies on the heritability of personality characteristics have shown that genetics may play a part in the temperament of a child which builds the base of the personality of an individual as they develop. A study by Sandra Scarr, psychology professor with a PhD from Harvard, conducted an experiment testing the biological basis of introversion and extroversion by assessing the personalities of 61 pairs of twin girls through interviews, tests, and games. Twins were used in this study since identical twins contain the same exact genes and fraternal twins share an average of 50% of their genes. By observing how closely the twins resembled one another compared to the variances, she determined the interclass correlation. Through the experiment, high correlation was found which led to the conclusion that there is a moderate to high genetic contribution to social introversion-extroversion. (Scarr 825-826). Though this may have been proven, it does not necessarily mean that whether you are introverted or extraverted is wholly based on the genes that you
Personality types stems from Carl Jung spend time observing personality preferences, which he later on published in his in 1921. Carl’s discovery of the two major typical differences in human psychology such as extrovert and introvert influenced Katherine Cook Briggs and her daughter Isabel Myers theories and lead them to experiment during World War II. Myers and Briggs worked on methods that would help women, who heretofore had no prior workplace experience, find those types of jobs that were most comfortable and effective (Myers & Myers, 1996). The three learning styles I have chosen to write about would meet the needs of the learners and provide an effective learner/teacher experience. Therefore, the need for learning level in people varies at all levels, to make sure the delivery method meets the learners’ expectation, it is important to re-evaluate the styles of learning chosen and make sure all background
Psychologists have shown that there exist two major social behaviors that are widely associated with a person as they mature into young adulthood: extraversion or introversion. Carl Yung, a swiss psychiatrist and psychoanalyst, coined the term “introversion” versus “extroversion”. His idea was further elaborated upon by Hens Eysenck, a British psychologist, who defined extroverts and introverts by their baseline arousal. As Jerome Kagan, Professor of psychology at Harvard says, ““Introverts” and “extroverts” are not definitive diagnoses like blood types”, a person displays more or less of one of these two traits; extroverts generally has a more advantage over introverts but each of these personality traits has its own strengths and building on these strengths is what one ought
A layman would define personality as an individual’s characteristics in terms of how they think and behave. Many theorists, however, interprets personality differently resulting in various personality theories. Personality is determined by traits which are behaviours displayed by a person in most given situations. How a person reacts to common circumstances may also be used to foresee future behaviours. Traits are then categorized into types that allow easier comparisons to be made between each individual’s attributes. The focus of this paper would be on the biological aspects of personality whereby traits are thought to be inheritable through genetics and associated with the central nervous system. Behavioural genetics are research that makes use of results from studies done on family, twins and adoptions. The findings of how both genes and environment influences personality from the studies will be discussed. Some researchers found possible issues with the representativeness of such studies. The outline of Eysenck’s biological model of personality and arousal, Gray’s BAS/BIS theory and Cloninger’s biological model of personality will further explain the biological effect on personality.
I think that there is no fixed statistic. For instance, it isn 't sixteen percent genes and eighty four percent experience. I think it fluctuates between people. I might have thirty percent genes and seventy percent experience making who I am, while my sister may have forty percent genes and sixty percent experience making her personality. I think the reason identical twins are so similar in personality are because when they split in the womb, they already have their characteristics like hair color and any eye color in their genetic makeup, so why not their genetic trait and experience percentage? So while identical twins might be, for lack of a better word, identical, siblings will be similar but not carbon copies in terms of personality. I also think the personality genes you get will be either reinforced or pushed back as you get experience. If a empathic young boy is told by stern parents that “girly” sad feelings aren 't “manly” he will push back that empathic part of him that came through genetics and repress it. Hopefully he will realize one day that his parents social constructs put on him are illogical and go back to the empathic part of him, but the damage by experience could be done and
Many conducted research by looking into identical twins and their personality types. Even when the twins were separated, they expressed some of the same behaviors and traits as their twin which concluded that some traits are inheritable. This thought can go deeper into the brain through a domain called personality neuroscience where people have discovered the dopamine receptor gene (Pastorino & Doyle-Portillo, pg. 479, 2015). This gene influences the amount of serotonin in the brain and can cause greater anxiety levels in these people. The founding of this gene solidifies the fact that biology and personality are indeed
For example, when asked a question at work I often answer with “give me just one second”, or “ill get back to you”. Most introverts need time for internal reflection. A chance to process the question and think about my response. Introverts make great listeners, are studious, and are okay with solitary activities (The Personality Page, n.d.). However, most introverts have a hard time with external communication and are sometimes perceived as being non-social (The Personality Page,
“ …my first concern must be with the two general types I have termed introverted and extraverted. But, in addition, I shall also try to give a certain characterization of those special types whose particularity is due to the fact that his most differentiated function plays the principal role in an individual's adaptation or orientation to life.” (Jung)
A study in 1986 in Minnesota found that genetics play a larger role on personality then it was to be previously thought to be.
When discussing extraversion-introversion, there does not seem to be a plethora of similarities simply because the two are on opposite ends of the continuum (Peake, 2014, p. 8). Differences on the other hand are identified much easier between the two. One main difference is the way individuals perceive each trait. Extraversion is seen as a good quality and is often used as a positive trait. Although it is not entirely true, introversion is looked at as a negative trait for someone to possess in today’s’ society (Peake, 2014, p. 8). The best way to explain how these two traits differ would be the type of stimuli that motivates
According to Lukaszewski and Roney (2010), although much is known about the psychophysiological and behavioral correlates of this trait, much less is understood about the origins of individual differences along this dimension. In their research, Lukaszewski and Roney suggest that physical attractiveness or both men and women, as well as physical strength especially in men, exhibited independent positive links with extraversion. Cherry (2015), assert that extroversion has been linked to genetics and studies in genetics show that genetics contribute a significant percentage of the variance between introversion and extraversion. Extraversion has also been associated with the environment in that an environment can have an influence in causing this trait. According to Cherry, studies on siblings show that individual experiences have a significant influence than shared experiences in families. Thirdly, some research shows that the variability in extraversion might be connected to the variations in cortical arousal. This suggests that people high in extraversion are more likely to require external stimulation while those low in the trait are more likely to become stimulated with
On the other hand, introverts are people who are concerned with and interested in their own mental life and often perceived as more reserved and less outspoken in groups. Unlike extroverts who are feeling energized when they are around a large group of people, introverts have energy drained from them through human interaction. Hence, it is essential for them to spend some alone time to “recharge”. Al...
Being an introvert should be seen as someone who simply finds pleasure, relaxation, calmness, satisfaction, and tranquility with being by him/herself, a person who feels that loneliness, on the most literal and non harmful level,
There are two distinct personality types: introverts and extroverts. Introverts like to keep their thoughts to themselves and prefer to be alone; however, introverts are not always shy. On the other hand, extroverts are comfortable with sharing their ideas and opening up to others quickly. According to Anthony Hilling in “Extrovert and Introvert—what is the difference?, “It is wrong to think of introverts as being antisocial.” Furthermore, introverts and extroverts choose to socialize differently. Carl Jung defines “introversion as an attitude-type characterised by orientation in life through subjective psychic contents (focus on one's inner psychic activity).” Introverts are known for articulating their thoughts clearly in writing because they “tend to stop, reflect and absorb information before speaking, they reflect this kind of deliberate thought in their writing.” There is an apparent difference between the two personality types, explaining why many people believe that introverts and ex...
Trait approach covers the big five personality traits: extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. These five traits have been identified as the most identifiable personality traits, even across cultures and societies. According to McCrae, Costa, and Busch’s (1986) study on personality system comprehensiveness, the big five personality model included the five traits most identified with by individuals asked to describe themselves and others. I found this segment of the class especially intriguing as it helped me not only learn so much about myself, but also take a deeper look into the personality of my family, peers, and even strangers. I am also more conscious of how I self-monitor my personality traits. For example, I am very much so an introverted person but at times I try to be extroverted based off the environment. In highly social environments, I consciously smile and try to talk to people because I want to be perceived in a favorable light, not actually because I feel the need to be sociable. In other words, I don’t want to be perceived as odd. I believe I developed this form of self-monitoring because when I am introverted at social events people will constantly ask me if I’m ok since I’m quiet, which makes me uncomfortable as they make me the focus. Being the center of attention makes me anxious, and therefore to prevent that I have developed being a fake-extrovert to avoid it. This exemplified how I apply self-monitoring to my everyday life. Trait approach gave me insight into how to identify vastly accepted personality traits, as well as, how each of these traits can be influenced and
479). Throughout my life, I have always been described by teachers, friends, and family as an introvert. I’m shy around other people and often have a difficult time talking to them. In school, I’m the student that the teacher doesn’t know if I’m in class or not, unless I participate in discussions. It was interesting to learn more about introversion by reading about it in the book and the discussions in class. I was intrigued by the research information in the book, “shyness has a strong biological influence” (Grison, Heatherton,Gazzaniga, 2017, p. 484). My grandfather displayed the same quiet nature. Whenever, I went to my grandparent’s home, I noticed how he sat and listened intently to others, but didn’t speak much. He has always had a quiet nature. In addition, I learned more about the trait from the Eysenck’s Biological Trait Theory of Personality, which described how “personality traits had two major dimensions:
