3. Dr. Nation is a biopsychologist interested in studying fluences on brain development. Briefly describe a twin study Dr. Nation might design to investigate the research question: \"How do genetics and early environmental influences interact to impaçt how brains yd develop?\" Use the following terms in context in your description: 1 Tnhevrtwee Tuobidagr in Genes .

Solution

Dr. Nation may design a research study to identify what are the genetic and environmental factors which impact the brain development. He may design a study in which the sample may be fraternal twins who are being reared by different parents. This means that Dr. Nation will have two different groups, each group comprising of one of the fraternal twins who are reared apart. Then each group must be assessed on some of the variables like personality characteristics, problem solving or decision making skills. They may also be tested on how they emote or how they appraise a situation using fMRI or biofeedback. This will result in the identification of epigenetic influences on behavior of the twins. The results will thus allow Dr. Nation to see how heritability or genes interact with environmental factors to determine the behavior of an individual.
