Explain the 3 theoretical perspectives explaining human behavior and which is most valid There are three theoretical perspectives that account for human behavior, with varying degrees of efficacy. These include evolutionary psychology, behavioral genetics, and behavioral neuroscience. Each theoretical framework makes intellectual sense and can claim to explain human behavioral in a general sense. At the same time, they take vastly different attitudes toward the way in which the human brain operates, and the theoretical perspectives should not be viewed as inherently equal in value. First, this paper offers a broad overview of the governing principles associated with each of the frameworks. Then, the analysis shifts to a consideration of which approach is most valid. Evolutionary psychology accounts for the continuous process of adaptation undertaken in order to better adapt to one's surroundings. As argued by Tooby and Cosmides (2005), evolutionary psychology treats the brain as a "computer designed by natural selection to extract information from the environment" (p. 18). Human behavior is thus determined by the interaction between a person's cognitive faculties (the computer) and their environment. Evolutionary psychology sees the history of mankind as a continuous process of adaptation; it therefore places great emphasis on the role that one's surroundings play in determining their behavior. For example, if a person lives in an environment that is particularly warm
