Personality is influenced by both heredity and environment. When it comes to behavioral outcomes, twin studies have indicated that heredity plays a larger impact than parental effects, but non-shared environmental variables play an even bigger part. These findings are consistent across cultures and time periods, indicating that they reflect fundamental properties of the mind.
Heredity affects personality development through two main channels: genetics and learning. Genetics influences who will develop what traits and how much influence each of these factors will have. Learning refers to any experience that changes or modifies existing characteristics or traits. For example, if one experiences pain when touching hot objects then this will modify future decisions about whether to touch hot objects. Learning also includes any other experience that alters your behavior, such as reading books or watching movies. This article focuses on genetic influences on personality development.
Genetics plays a role in determining who will develop certain traits and how much influence this factor will have. For example, if one identical twin develops schizophrenia while another does not, this shows that genetics plays a role in determining which individuals will develop this disease. The same can be said for other diseases or conditions where there are multiple cases within a family. In most cases, genetics is responsible for causing these illnesses to manifest themselves.
Environments also play a role in determining who will develop certain traits and how much influence this factor will have.
Variation within a group, not within a single individual. Genetics contributes approximately half of the variation in personality characteristics. The remaining 50% is mostly the result of non-shared environmental variables. Personality self-ratings are unaffected by shared settings. What effect does genetics have on personality? It influences how each of us expresses our traits. If you had no other choice than to choose between an identical twin and a different person with a similar background and upbringing, it would be sensible to assume that they would show more similarities than differences in their personalities. However, this isn't always the case. Sometimes twins develop differences in personality due to different experiences. For example, one twin may have better luck with friends or may get into more fights. This would lead to them developing differently.
Genetics play a role in who shows what traits and how people vary in their responses to situations. Some traits are passed down through genes while others are learned through environment. For example, your behavior when faced with a threat might be influenced by whether you have the instinctual fear response or not. Someone without this response might come across as unfazed by a dangerous situation. On the other hand, someone who does have the fear response might appear nervous before acting bravely in order to protect themselves.
Personality is defined as a set of consistent behaviors and attitudes toward life. It can be described as a collection of traits that shape how someone interacts with others and handles stressors in their daily lives.
Personality characteristics are influenced by both inheritance and environmental influences. Although a person's environment influences his personality development, hereditary factors have a bigger role in determining the disposition of this environment. For example, if one of my children was given a negative impression of psychologists at a very early age, this would influence their view of therapists generally. The same could be said of a positive impression made at a young age with psychics or fortune tellers.
Here are some other ways that the environment can affect a person's personality:
If you grow up in a house with many books, you're more likely to enjoy reading as an adult. Even if your parents don't read themselves, they can encourage the habit in their children by buying them books.
The environment you grow up in affects how your body functions. If you're raised in an area where it's cold or hot, your body will adjust to fit its environment. This means that if you live in a cold climate as a child, your body will develop certain mechanisms to keep itself warm. This is why kids who are raised in cold climates tend to have poor circulation. They need to spend more time under artificial heat lamps or in front of fireplaces to keep themselves warm.
