There are two broad classifications of twins. Only certain types of twins are qualified in the tests done regarding predetermined personalities. Fraternal twins, perhaps the most common of the two, grow separately from two eggs united with two different sperm cells ("What's"). Because they are virtually two different beings that grow independent of one another they are a lot less similar then identical twins. Dizygotic, as they are also known, share only 50% of similar genes and are, in fact, no more genetically alike then two single born siblings ("Twins"). Because of this, most of their traits are discordant, meaning shared by only one of the two twins, just like a brother and sister having completely different personalities. People tend to think that twins are twins, but the differences between identical and fraternal twins are so vast that the fraternal "twins" are no more than two non-genetically connected siblings born at the same time. (Brandt) Even if they seem similar when they are young, as the aging process begins every year they grow less alike ("What's"). In conclusion, I, as well as many others see that twins of this nature possess little possibility of their personalities being predetermined, and thus they are not used in testing due to the fact that their genetics are practically irrelevant. .
On the other hand, identical twins are not at all similar to that of fraternal twins and open up a whole new window, wide with scientific opportunity. Monozygotic, as they are technically categorized, are born when a single egg and sperm unite and an ovum splits into two separate halves ("Twins"). In essence one ovum with the potentiality of growing into a single child splits into two different beings. Because of this, identical twins share nearly 100% of genetic similarity ("Twins"). And so, babies develop together for nine months from one into two, feeding and nurturing off one another.
The second types of twins are fraternal twins. ... Fraternal twins are twice as common as identical twins. ... Three distinct outcomes within the twin categories are mirror image twins, half-identical twins, and conjoined twins. Some identical twins are mirror image twins. ... Areas such as transpersonal psychology. ...

Wilhelm Wundt (1832-1920) And His Contributions to Psychology The formal launching of the separate field of psychology is usually credited to Wilhelm Wundt for his Laboratory of Psychology, which was started in Leipzig, Germany, in 1879. ...

The contrasting views of the two groups had begun the nature vs. nurture debate, which would linger in the fields of philosophy and psychology for decades. ... The theory quickly gained notoriety in psychology and swayed popularity to the nurture side. ... From the 1920s to 1950s, behaviorism and nurturism dominated psychology. ... The most resent studies that have been done on twins and adoption use both identical and fraternal twins. ... Identical twins are 100% genetically similar and offer exact genetic replicas to study, where fraternal twins are the same as any other siblings at 50% si...
And thus there exists the "Nature versus nurture" controversy that has perplexed psychologists since the birth of modern psychology. ... Adoption studies usually focus on identical twins separated at birth. "Because the twins have identical genes, differences between them with respect to various aspects of behavior can reasonably be attributed to environmental factors," (Baron, 69). ... In a video showed in my psychology 101 class on February 3, 2003 entitled "The New Living Body," we learned that children are born with a certain amount of connection points, or synapse. ... The "nature vs. n...
Studies of twins provide evidence for this genetic influence. Among genetically identical twins where one twin has bipolar disorder, the other twin has a 50 percent chance of also having the disorder. ... The amount of genetic similarity seems to explain for the difference between identical and fraternal twins. ... (psychology today, 87) Yet other drugs used are antidepressants. ...

Whereas developmental psychology and social psychology have merged as a subject matter in psychology, personality has never truly found that unity. ... Another research method to this perspective is twin/adoptee studies. ... There are problems with the twin research methods. Researchers who use the twin-study method make two key assumptions. First that twin pairs can be accurately identified as MZ or DZ twins and secondly that MZ and DZ twins have equally similar environments. ...
. Within society psychology has suggested that there is strong link between our experiences as a child affect our adult behavior and feelings. ...
