Final answer:
In adult development, when experience conflicts with existing schemas, the psychological concept that is relevant is accommodation.
Step-by-step explanation:
In adult development, when experience conflicts with existing schemas, the psychological concept that is relevant is accommodation. Accommodation is the process of adjusting or changing existing schemas to incorporate new information that is different from what is already known. It occurs when individuals encounter new experiences or information that does not fit into their existing ways of thinking.
For example, suppose an adult has a schema that all birds can fly. If they encounter an ostrich, which is a bird that cannot fly, there is conflict between their existing schema and the new information. In order to resolve this conflict, they would need to accommodate their schema by revising their belief about birds.
Therefore, the correct answer is B) Accommodation.
