Final answer:
The correct answer is a) Assimilation; Accommodation. These terms were described by Jean Piaget and are central to the cognitive development process, involving the integration and adjustment of schemas in response to new information.
Step-by-step explanation:
The process of incorporating new information into existing knowledge is known as assimilation, whereas the process of adjusting our schemas to fit new information and events is known as accommodation. Therefore, the correct answer to the student's question is: a) Assimilation; Accommodation. Jean Piaget, a well-known developmental psychologist, described these two key processes of cognitive development, where assimilation involves integrating new experiences into existing schemas without changing them, and accommodation refers to altering the existing schemas or creating new ones in response to new experiences or information.
