Реферат: Nurture Plus Nature Essay Research Paper Nurture

misbehaviors are related to genetic aspects and which are associated with

behavioral decisions when discipline is necessary.

Psychologists such as Turecki, Rowe, Alexander, Chess and numerous

others have all added contributing ideas and research to the point of nature

plus nurture, but one man’s revolutionary research and ideas could not be

ignored on this subject. Thomas J. Bouchard’s famous studies on twins at the

University of Minnesota allowed the comparison between exact human genetic

copies (”John Bouchard” Encarta Encyclopedia). These unique experiments modified

the scientific views of genetic similarities and the influence of environmental

surroundings. This research conducted by Bouchard and other twin researchers

also presented accurate information on the importance of heredity and

environment (Turecki). Similarities between identical and even fraternal twins

supports the superior importance of a genetical impact on behavior. In the

opposite view, however, differences intervening between behaviors of identical

or fraternal twins defends the importance of the upbringing environment (Rathus

p.112).

Research in this subject, originating from Bouchard and others, has

revealed an extensive range of similarities between identical twins raised

together and separately. It is evident that two children sharing all one hundred

percent of their genetic makeup (identical) will present several similarities,

compared to children that only share fifty percent of similar genes. The

physical appearance of identical twins will obviously be more alike in

resemblance, height, weight, and even have more closely related blood

cholesterol levels, than fraternal twins, or other siblings altogether (Rathus

p.112). By studying identical twins that had grown up separate from each other,

Bouchard was appalled by the similarities that endured just as though they had

been reared in the exact environment. Some of these strong behavioral traits

included shyness, activity levels, risk aversion, achievement, optimism,

irritability, sociability, cognitive development, physical gestures, patterns of
