Recommended: Heredity as biological determinant of behavior
Genetic research has the potential to make a huge impact in the field of child development. Behavior that a person inhibits is somewhat influenced by the genes that they inherit. As a result, genetics is and will continue to generate advancements in the biological, cognitive and social areas of child development. This is due to the fact that behavior is the result of biological and cognitive processes and influences social growth. What is known about genetics and behavior is that genetics play a role in the behaviors exhibited by an individual and is indirectly able to influence their environment as well. Genetic research is rooted in the field of behavioral genetics which aims to understand how we inherit certain behaviors and how the environment
...s may never agree on a conclusive degree to which both nature and nurture play roles in human development, but over the years, more improved studies have shown that both are crucial aspects. With all the knowledge we are gaining from these studies, it would be quite limiting to believe that a criminal and his actions are the sole result of heredity. Even in people who do not commit crimes, genes themselves are affected by the prenatal environment. Undoubtedly, the fetus experiences changes in environment, forcing possible changes in heredity and reactionary response. We are likely to never find the answer to how much or how little either, nature or nurture, impacts our lives, but at least we can agree that they both do, in fact, have major roles. Our development is not the culmination of heredity alone, but of a tangled web of experiences and genetics entwined.
The nature vs. nurture debate: the nature side, are those such as biologists, psychologists and others in the natural sciences, argue that behavioral traits can be explained by genetics. Those taking the nurture side are sociologists and others in the social sciences, they argue that human behavior is learned and shaped through social interaction. This argument should be dismissed because you don’t have to look far to see that both genetics and our environment, plays a role in who we are and our behaviors. (Glass). The point is there is a complex relationship between nature and nurture, either one alone is insufficient to explain what makes us human. (Colt). Our heredity gives us a basic potential,...
Some factors that are explored in studies involves the genetics in a person, how parents treat their children, influences peers have and the situations that a person may experience throughout their childhood and adult life. There is a possible connection between the feelings of anxiety, aggression and fear with a genetic makeup in a person’s body (Huff, 2004). Research has even shown that if an individual was abuse, whether physical or verbally they are at risk for developing a personality disorder as well (Huff, 2004). Another interesting study conducted by Robert Krueger, PhD, exploring the influences that can contribute to the development of a personality disorder, looks at studying personality traits within identical twins who did not grow up together. In the study, it appeared that genetics contributed more to a person personality trait then the environment they were in. Krueger opinion was that “The predominant reason normal and abnormal personality are linked to each other is because they are linked to the same underlying genetic mechanisms” (Huff,
Genetics has a great impact on the person one becomes starting with their early development. The Genetic Model will access the gene mutations that affect the individuals. Gene mutations such as, the altering of proteins which in return changes the functions of the brain (McNeece & DiNitto, 2012). Likewise, the individual may be more prone to develop a addiction due to this mutation. Also, genetics can affect the behaviors of an individual participating in the use of drugs. Once a parent participates in drugs and their desires it reflects onto the child’s behaviors and their desire with the use of drugs. These desires are stored in the limbic part of
Having understood that genetics do play a part in the actions of an individual, solving the question of how much of it is in part of the biological makeup. There is clear evidence from studies that about 50% of the deviation of antisocial behavior is derived from genetics. The question has now been changed to “Which genes predispose to which kinds of antisocial behavior?” (Raine, 2008)
Epigenetics is the study of how inherited traits are expressed and influenced by the environment, and it is extremely complex. Joseph Nadeau has traced over one hundred biochemical, physiological, and behavioral traits affected by epigenetics. He has seen them be passed down through several generations (Blum, et al, 2010). ADHD, which has been linked to anti-social behavior, is thought to have epigenetic roots. In one adoption-based study done by a group of colleagues, they found that if the mother was an alcoholic or a criminal, the child was at great risk for ADHD. If the father was criminal, the child was also at an increased risk, but having an alcoholic father did not seem to have any effects of the offspring in terms of developing ADHD (Beaver, Nedelec, et al, 2011). Criminal behavior would be the genetic control, and alcoholism would be the environmental factor. Even though they both play a role, genes are still the platform the environment works on to create what ...
As a mother, I am shocked and dismayed by the general acceptance of the myth of genetic determinism. One's environment, including people one interacts with, has an undeniable influence on how one develops. Nonetheless, many scientists disregard the impact of environment on one's intelligence. I do not deny that one's biology is a crucial part of one's identity. Inheritance of physical traits is obvious. Children often look "just like" their father or mother, or another relative. One's genes determine eye and hair color, height and body build. I believe, however, that what makes us human is not something that can be found in...
Evolutionary theory is developed from Darwin’s argument that “suggests that a process of natural selection leads to the survival of the fittest and the development of traits that enable a species to adept to its environment. “ Many have taken this a step further by saying that our genetic inheritance determines not only our physical traits but also certain personality traits and social behaviors. There is such a controversy over significant behaviors that unfold because many believe that we are already pre-programmed human species. It has also been argued that evolution is reflected in functioning and structure of the nervous system and that is has evolutionary factors that have a significant influence on everyday behavior. With what is being said means that if we follow the evolutionary theory, then it would be said that we are already pre-programmed from before birth to follow certain protocols in life. Whether it is from finding a mate or by getting a job. It also believed that this theory gives use cues from our own system to follow, providing us with certain aspects of life from our ancestors. By believing in this theory we can determine that the importance of heredity when influencing human behavior. Behavioral geneticists and evolutionary psychologists have both agreed that not only do genetic factors provide specific behaviors or traits but it also shows the limitations on the emergence of such traits or behaviors. What this means is that our genetics will determine how tall we will be to how ...
Behavioral genetics is a field of research that investigates the relative effects of heredity and environment on behavior and ability (Plomin, 1997). Two of the primary methods used by behavioral geneticists are the twin study method, first used by Galton (1975) in his studies of heredity, and the adoption method.
Someone can physically look like their parents, siblings or even ancestors from the third generation. When a baby is born, it is common to learn in a natural way. No one teaches a baby how to crawl or how to react when he and she is hungry. However, talents, qualities and personalities are developed through experiences. The environment in which people grew up can have a lasting effect or influence on the way they talk, behave and respond to things around. According to Steven Pinker, Behavioral genetics has shown that temperament emerges early in life and remains fairly constant throughout the life span, that much of the variation among people within a culture comes from differences in genes, and that in some cases particular genes can be tied to aspects of cognition, language, and personality (2). Researchers believe that the origin of behaviors occur in genes in the DNA or even animal instincts which this concept is known as nature of human behavior. Other researchers believe that people are they were they are because they are taught to do so. This concept is well known as nurture in human behavior. In society, there will always be the doubt between Do we born in this way or do we behave according to life experiences? I strongly believe that nurture plays an important role in the upbringing of a child and the decisions that one makes in the future. Firstly, humans learn from their environment and other’s behaviors. Secondly, culture is a huge remark in people’s life. Finally,
Undoubtedly, humans are unique and intricate creatures and their development is a complex process. It is this process that leads people to question, is a child’s development influenced by genetics or their environment? This long debate has been at the forefront of psychology for countless decades now and is better known as “Nature versus Nurture”. The continuous controversy over whether or not children develop their psychological attributes based on genetics (nature) or the way in which they have been raised (nurture) has occupied the minds of psychologists for years. Through thorough reading of experiments, studies, and discussions however, it is easy to be convinced that nurture does play a far more important in the development of a human than nature.
From preschool into early elementary school, children have begun to develop their gross motor skills. They have developed a “mature pattern of walking” and are ready to test their physical abilities to the limits. Also fine motor skills have begun to develop, however more slowly. Along with motor skills children are developing their visual, tactile, and kinesthetic senses. A child’s sensory skills are helpful in learning language.
The distinction between nature versus nurture or even environment versus heredity leads to the question of: does the direct environment or the nature surrounding an adolescent directly influence acts of delinquency, later progressing further into more radical crimes such as murder or psychotic manifestation, or is it directly linked to the hereditary traits and genes passed down from that individual adolescent’s biological parents? To answer this question one must first understand the difference between nature, nurture, environment, and heredity. Nurture, broken down further into environment, is defined as various external or environmental factors one is exposed to which can be more specifically broken down into social and physical aspects. Nature, itself broken down into heredity, is defined as the genetics and the individual characteristics in one’s personality or even human nature.
Genetics is a scientific discipline that deals with how individuals inherit their physical and behavioral attributes. Generally, genetics is a branch of biology that deals with the science of heredity, genes, and differences in living organisms. It’s the process with which a child inherits traits from his/her parents and the molecular organization and function of genes. The question of what determines the development of a child has been an issue that has attracted considerable concerns and debates across educators, biologists, and psychologists. This issue has attracted huge concerns because it’s impossible to explain each and every factor that eventually determines who a child becomes. Notably, the development of a child involves a mix of various influences such as parenting, genetics, individual experiences, family relationships, friends, and school. One of the most important influences on a child’s development and growth is genetics, which primarily is the process of traits inheritance from parents to offspring.
Height, hair color, eye color and sex are just a few examples of ways our DNA has shaped us. But could it be possible that our DNA also effects the way we behave in society. It is possible that genetics effect us is more ways that we may have imagined. Dr. Peter B. Neubaur believes that shyness, eating disorders, obsessive behavior and psychological illness can all be traced back to our genetics. Sexual orientation is also believed to be derived from genes in our body which determine what sexual preference we prefer. Violence and other types of crimes can be linked back throughout a person’s lineage to witness that other family members have been committed similar crimes without ever meeting one and other.
