Twin study

of; the nature, nurture debate. It will do so by examining twin and adoption studies. Through compiling results from various studies conducted by researchers and academics, it will demonstrate inconsistencies, which in turn conclude that human mental processes, and behavior cannot be determined by one specific factor. The nature, nurture debate is a widely regarded topic of inquiry, which aims to define the prevalent force behind an individual’s personality, identity and behavior. For humans as a species, it is important to discover to what extent external or learned behavior, and internal or hereditary behavior, affects our mental process, and in turn, our identity (A. Tomlinson, 2010). Over…

Have you ever thought about what it would be like to be a twin? Would your personality or behavior be any different or would genetics determine your development? In recent years, twin studies have been more relevant because of the fascination of nature (environment) versus nurture (genes). Scientists and psychologists are well aware of the nature versus nurture effect but with technological advances, it is taken to a whole new level. Researchers are able to look more deeply into what the…

not do well in school. As said by Kovas and Haworth, (2007), scholastic achievement to some degree is passed down genetically. The twin study done by Hanscombe, Haworth, Davis, Jaffee, and Plomin (2011) was to examine the genetic and environmental factors that link disorderly and chaotic homes and how well a child does in school. Identical twins share one hundred percent of their DNA, while non-identical twins only share fifty percent of their DNA. Hanscombe, Haworth, Davis, Jaffee, and Plomin…

The study used a high selected sample called Twins Early Development Study (TEDS) sample which presents the U.K. population. All children having serious medical or psychiatric problems were excluded from the analysis of the research. Both of same-sex and opposite0sex twin pairs were included in the research (Rimfeld, Dale, Kovas and Plomin, 2016).…

The perusal and review of twin, adoption, and family studies allows us to understand how the combination of biology and environment shapes us all. Some aspects of personality are linked to genes and have a biological basis, but it has allows been hard to separate biological basis of behavior from an environmental basis of behavior. Twin studies are a vastly important tool in dissecting the nature versus nurture argument. Pros of twin studies are that identical twins otherwise known as…

According to studies done on biological siblings adopted by two different middle class families, it shows as the siblings grow older and live apart from their adoptive families their IQs became more similar (Ceci). The reason for this is because siblings pick similar environments since they share 50 percent of their genes, which shows the impact nurture has on their IQs as well (Ceci). This shows how genetics and nature are more powerful in making siblings alike than similarities in their home…

Intelligence If you had been raised in a different environment, there are people who will say you would be just as intelligent as you are now, but there are also people who will say you would not have the same intelligence. For many years, psychologists have researched where intelligence comes from. Some say your intelligence is from nature. Some say it is from nurture. Others will say it is a combination of the two. The intelligence of a human has always been a controversy between nature,…

And that includes your childhood, how you are raised, just basically our surroundings from when we were a baby up until where we are today. But which side of the argument has a greater impact on humans? Nature or nurture? Everyone has their own opinion whether is nature or nurture. Both sides of the argument has valid evidence and arguments. However, I strongly believe nurture, or your surroundings, has a greater influence on us humans for many reasons. There are many great studies that prove…

The environment that the individual lives in also has an significant impact on the personality and behavior of that individual. It is important to test nature and nurture on identical twins because this way you can eliminate a factor, nature, and control and change the environment factor. Wright concludes that, since identical sisters share the same genetic makeup, you can predict and analyze the effects of their environment on their personalities (Wright). It is easier to study the effects of…

Behavioral Genetics, 2016). Although the theory of primitive behavioral genetics cannot be tested to prove the accuracy and influence, there are many other studies that are performed to help determine what has the strongest impact on creating a persons personality; this is the nature versus nurture debate. The thought that nature reigns supreme to nurture means that the natural and instinctual “reflexes”…
