The nature-nurture debate of intelligence and IQ dated back to the age of phrenology when scientists thought that the size of one's brain mean much about their intelligence ~ the bigger your brain, the higher your level of intelligence.

This means that sleep length has a low heritability. NATURE VS NURTURE NATURE Biological- usually called "genetic", but actually more complicated, ill-defined. There are two types of twins: monozygotic (MZ) and dizygotic (DZ). Psychologists try to compare the influence of heritability and the environment by taking advantage of the idea that monozygotic twins share 100 percent of their genes .

However, there have been a lot of debates about this even in recent times when complex and sophisticated .

How much of our identity is conferred by our genes, and how much is a product of the environment in which we are raised? But it is even worse if that trait depends on the combination of two or more genes. Over 60 per cent of a child's intelligence is passed down from the parents - much more than previously believed, say scientists.

James Lewis and James Springer together with over 100 subjects were studied. Nature is your genes.

If a person's genes solely cause schizophrenia, than if . NURTURE Social - usually considered family background, education, socio-economic influences, ill-defined .

Results of two real-world twin studies. Behaviorism is a school of psychology that is on the side of nurture. empiricism or behaviorism). Photo courtesy of Shutterstock A culmination of more than half a century of research collected on 14.5 million pairs of twins has finally concluded that the nature versus nurture debate is a draw.

The studies conducted on twins show that genes greatly affect intelligence. A study was done that showed evidence of 20 to 40 percent of a person 's intelligence is based on genetics. Many of these studies have focused on similarities and differences in IQ within families, particularly looking at adopted children and twins. According to twin studies, genetics accounts for approximately 50 percent of individual differences in intelligence. Twin studies have been used to investigate this debate further and from these studies we can see that genetics can play a huge role in influencing a person's IQ. Intelligence is challenging to study, in part because it can be defined and measured in . This debate strings together all aspects to conclude if personality is shaped by nature or nurture.

According to Spearman, intelligence is natural in that you either have the g-factor or not (Anderson, 1999). The present study proposes to address the lack of research in this area by examining the heritability of leadership style, as measured by self-report psychometric inventories. Dr. 1. The twin studies reveal the absolute and relative significance of genetic and environmental influence on one's intelligence. Intelligence: Nature vs. Nurture.

Studies have shown that when one set of identical twins developed a predisposed disease (e.g., schizophrenia), there's a fifty-percent chance of the other twin inheriting that same condition (Anonymous, 2005). The study shows that the average population has a 10% chance of being schizophrenic.
