The nature vs. nurture debate is one of the longest in the field of psychology. It is concerned with the importance of individual’s inborn qualities, their nature, versus their personal experience or their “nurture”(Ceci & Williams, 2000). Many psychologists disagree as to which plays a more important role on an individual. Psychologist Donald Hebb is said to have answered the question of which contributed more to the personality of a person with the response, “which contributes more to the area of a rectangle, its length or its width? (Ceci & Williams, 2000)”

It is somewhat difficult to determine whether a trait is formed through heredity or from the environment (Ceci & Williams, 2000). One way in which researchers go about the process is by studying twins. Researchers study the behavioral similarities between identical twins and that of fraternal twins. Fraternal twins are no more genetically alike than regular brothers and sisters while identical twins are
