Development Across the Life Span: Nature versus Nurture
Barry University
What is Nature versus Nurture?
Development across the lifespan is one of the most interesting areas of psychology. The word development refers to human development which can be defined as “the scientific study of changes that occur in people as they age from conception until death.” (Ciccarelli, & White, 2009)Psychologists study this developmental change over time through several different methods. The book highlights three: Longitudinal design, cross-sectional design and cross-sequential design. Longitudinal design is a research design “in which one participant or group of participants is studied over a long period of time.” Cross sectional design differs from longitudinal design because cross-sectional designed research studies “several different age-groups of participants are studied at one particular time.” (Ciccarelli, & White)Cross-sequential designed research is a combination of the other two types; the cross-sequential research design studies participants by means of a cross-sequential design but they are also followed and assessed for a period of time no more than six years.
A controversial topic associated with development across the lifespan is the theory of “Nature versus Nurture”. Nature versus nurture refers to the relationship between development and heredity and environmental factors. The answer lies on a spectrum between environmental factors and heredity. Psychologists on the environmental side are called empiricists. Empiricists believe that human development is fully influenced by a person’s environment. On the opposite side of the spectrum are the nativists. Nativists are psychologists that believe a person’s development is based completely on genetic factors.
The facts are divided in relation to the two theories; on one hand our DNA is “the instruction for all of an organisms traits” (Ciccarelli, & White, 2009). The DNA of a person is determined by
