One of the major controversies in developmental psychology centers if development is continuous or discontinuous. Those psychologists who support the continuous view of development suggest that development involves gradual and ongoing changes throughout the life span, with behavior in the earlier stages of development providing the basis of skills and abilities required for the next stages. Not all psychologists, however, agree that development is a continuous process. Some view development as a discontinuous process. They believe development involves distinct and separate stages with different kinds of behavior occurring in each stage. This suggests that the development of certain abilities in each stage, such as specific emotions or ways of thinking, have a definite starting and ending point. However, there is no exact time at which ability can appear or disappears. Although some types of thinking, feeling or behaving may seem to appear suddenly, it is more than likely that this has been developing gradually for some time. Stage theories of development rest on the assumption that development is a discontinuous process involving distinct stages which are characterized by qualitative differences in behavior. They also assume that the structure of the stages is not variable according to each individual, however the time of each stage may vary individually. Stage theories can be contrasted with continuous theories, which posit that development is an incremental process.
Why does an economic choice involve giving up something else? People make choices because they cannot have everything they want. All choices require giving up something (opportunity cost) Economic decision-making requires comparing both the opportunity cost and the monetary cost of choices with benefits.
