The question is this How can we distinguish between the milieual causes of behavior (the influence of parents, siblings, family, friends, schooling, nutrition, and all the other experiences to which a child is exposed) and patrimonial causes (those based on the genetic makeup of an individualistic that influence growth and development throughout life)?This question embodies the naturenurture issue. In this context, nature refers to hereditary factors, and nurture to environmental influences. Although the question was first posed as a nature-versus-nurture issue, developmental psychologists today stop that both nature Gerald Levey and Mark Newman 282 Chapter 8 dev elopment and nurture interact to set out particular proposition developmental patterns and outDevelopmental psychology The comes. Consequently, the question has evolved into How and to what degree branch of psychology that studies the do environment and genetic endowment both produce their effects?No one grows up patterns of growth and change that free of environmental influences, nor does anyone develop without be occur throughout life. affected by his or her inherited genetic makeup.

Despite their differences over theory, developmental psychologists concur on some points. They agree that genetic factors not only provide the potential for specific behaviors or traits to emerge, but also place limitations on the emergence of such behavi or or traits.For instance, heredity defines peoples general level of intelligence, setting an upper limit thatregardless of the quality of the environmentpeople cannot exceed. Heredity also places limits on physical abilities humans simply cannot run at a speed of 60 miles an hour, nor will they grow as tall as 10 feet, no weigh what the quality of their environment (Dodge, 2004 Pinker, 2004). Figure 1 lists some of the characteristics most affected by heredity. As you share these items, it is important to keep in mind that these characteristics are not entirely determined by heredity, for environmental factors also play a role.Developmental psychologists also agree that in most instances environmental factors play a critical role in enabling people to reach the potential capabilities that their genetic emphasise makes possible.
