Life span development studies are based on the idea that:

A. development occurs early in life, but not in late adulthood.
B. there is almost no continuity over the lifespan, so an individual’s history has little effect on development.
C. sociohistorical events affect development, but not enough to make any real difference.
D. every part of the lifespan is influenced by earlier events, and will in turn affect later events.

I choose D is that correct

I agree.

Yes, your answer is correct. Life span development studies are based on the idea that every part of the lifespan is influenced by earlier events, and will in turn affect later events. This means that development is a continuous and ongoing process that is shaped by previous experiences and interactions.

Yes, your answer "D" is correct. Life span development studies are based on the idea that every part of the lifespan is influenced by earlier events and experiences, and in turn, these earlier events and experiences will affect later events and development. This means that development is seen as a continuous process that is influenced by both biological and environmental factors throughout an individual's entire life. Researchers in the field of life span development examine how individuals change and develop physically, cognitively, and socioemotionally from conception to old age, taking into account the impact of earlier experiences and events on later development.
