The Nature-Nurture Issue The nature versus nurture perspectives have been have been argued for centuries. The pro-nature perspective follows the theory that genetics and biological inheritance determine behavior, internal forces or stimuli; the pro-nurture perspective follows the belief or theory that experience and environment determine behavior, external forces or external stimuli.
The psychology field known as biopsychology researches the aspects of both perspectives using critical thinking and research practices to determine the effects of both of these perspectives on human behavior; the control groups used in experimentation can be human or non-human subjects of a similar species. (Pinel. (2009)).
The flaw in attempting to determine what degree of behavior is attributed to nature and what degree is attributed to nurture is that both of these perspectives play a role in how and why a behavior is exhibited. Some of the behaviors which individuals exhibit can be linked to animal or primal instinct, these are behaviors based on nature; however, we must consider that the primal fears we have as children such as fear of the dark, often no longer exhibited in the individual as an adult.
This change in the behavior can be attributed to experience over time, the nurture perspective agrees with experience’s influence in behavior. (Pinel. (2009)). The brain is the central focus of the study of biopsychology, and researchers have determined that the brain’s functions are responsible for human behavior; research has determined the neuroplasticity theory of the brain changing based on both genetics and experience.
The neuroplasticity of the human brain can be used as an example of why it is important to consider how much of behavior is based on genetics and how much is based on environment; however, it would be difficult if not impossible to determine what portion of behavior is nature or nurture because both effect behavior based on the neuroplasticity theory There are genetic factors that can affect behavior; however, experience and nurturing can assist in controlling some behaviors based on learning or the xpectations set for an individual. This idea makes sense that both genetics (nature) and environment (nurture) play important roles in behavior, the behavior of an individual may change over the course of a lifetime. (Pinel. (2009)).
