Answer to Question 1
Answer: Researchers often investigate the effects of the environment on the development of personality. It used to be that any part of the phenotype that was not accounted for by genes was assumed to be due to the environment. Now researchers are interested in the dynamics of the environment. It has been identified that even if two people are in the same household or school they may not necessarily experience the same environment. One way of describing this is to define characteristics of an environment that essentially the same for two children. These aspects would be identified as shared environmental factors. If parents create an atmosphere of tolerance, for example, and are quite consistent about its application to two children this is part of their shared environment. In contrast, one child in a family may be treated as if they are quite bright and another, for various reasons, may be treated as if they are slow. There are many ways of addressing this and many examples that students can use; the basic definitions are the key feature for this question.
