Accommodation: is a term developed by psychologist Jean Piaget to describe what occurs when new information or experiences cause you to modify your existing schemas. Rather than make the new information fit into an existing schema, you change the schema in order to 'accommodate' the new information.

question
Research Question
answer
when there is little or no theory
question
Naturalistic Observation
answer
-everyday environment, permit researchers to see direct behaviors, unobtrusively watching and recording data -strength: reflects everyday weaknesses -Weak-:accuracy may be reduced b/c you cannot control it -example: they observed 3-4 yr olds and observed how kids reacted when others cried and how the caregivers reacted
