Inclues cultural values, polictical philosophies, economic patterns, and social conditions
an idea built more on the shared perceptions of society than on objective reality
Not primarily genetic, it is a product of the social environment and the individuals consciousness.
REPLICATION of research findings verifies the findings and leads researchers to more definitive and extensive conclusions.
In replicating researchm scientists use a different but related set of SUBJECTS. Repeating in order to achieve the same results.
A research design in which the same people are studied over a long time (which mught range from months to decades) to measure both change and stability as they age.
A systematic set of principles and generalizations that explains development, generates hypotheses, and provides a framework for future research.
Is is the purpose of developmental theories to provide solutions to most major developmental problem?

Paiget's step one:
reflexes; The newborns reflexes, such as sucking, grasping, staring, and listening, represent its only ways of gaining knowledge about the world. The newbornls first sensory motor activites are reflexes!!
Adaptation occurs in two ways
Assimilation and accommodation, of exsisting shemas to fit new information
Paiget's term for the stage 5 toddler who actively experiments to learn about the properties of objects,
