A nuture theory of human behavior

A nuture theory of human behavior The nature versus nurture debate is one of the most convoluted in the field of psychology. In the 17th century, a French philosopher, Renà © Descartes posited that â€Å"we all, as individual human beings, have certain innate ideas that enduringly underpin our approach to the world† (Crawford, 1989 p 64). The use of the terms â€Å"nature† and â€Å"nurture† henceforth has referred to the roles of heredity and environment respectively in human development. Some scientists believe that human beings behave as they do in response to genetic predisposition. This is known as the nature theory of human behavior and is the view espoused by naturalists (Scott, 1995). Other scientists think otherwise; that people think and behave in certain ways because they are taught to do so. This is known as nurture theory of human behavior and is the view of empiricists. Presented in the paper are the theories of nature vs. nurture, elucidation of perception, intelligence and perso nality within the debate. In addition, the paper discusses eevidences in favor of nurture and the influence of environment on behavior and morality. In exploring the nature versus the nurture debate, the writer presumes that nature endows human beings with inborn abilities and traits while nurture takes these genetic tendencies and molds them as humans learn and mature. Theories of Nature vs. Nurture According to naturalists, personality is natural. This group believes that personality is a result of evolutionary process. Human beings, it believes, inherit behaviors due to a complex interaction of genes. As such, genes control their behaviors. They believe that form and characteristics measured with personality tests remain stable throughout human life. They further believe that human beings may sharpen their types or personality but can never change them altogether. Darwin’s Theory of Evolution led naturalists such as George Williams, William Hamilton, and many others to the idea of personality evolution. They proposed that physical organs and personality is a result of natural selection (Herschkowitz, 2002). Human beings do as their genes dictate. In support, Steven Pinker (2004) includes conservativeness, religiousness and liberalism as gene related traits. William Paley, in agreement, believes cognitive capabilities, temperaments, and cheating behaviors are inheritable. There are however various assumptions about nature. Evolutionary psychologists believe that behaviour is a result of natural selection in the environment of evolutionary adaptation (EEA). Interpersonal attraction therefore can be explained as a consequence of sexual selection – men and women select partners who enhance their reproductive success (Crawford, 1989). Arguments for the supremacy of nurture posit that personality is nurtured. This group argues that one does not get personality from inheritance. They argue that the mind is a blank slate at birth. The definition of nu rture has extended to influence of development that emanates from prenatal, parental, peer influence and extending to the role of media, marketing and socio-economic status (Scott, 1995). They dispute that types and characteristics measured with personality tests change incessantly throughout one’s life. Harvard psychologist B. F. Skinner’s, experiments, produced birds that could dance and play tennis. Today, known as the father of behavioral science, Skinner ultimately went on to prove that human behavior could be conditioned in much the same way as animals. If environment did not play a part in determining an individual’s traits and behaviors, then identical twins should be the same in all respects, even if reared apart. However, a number of studies show that they are never exactly alike, even though they are remarkably similar in most respects (Michaels, 2001).
