Definitions:
Assimilation
A cognitive process in developmental psychology where individuals integrate new information into existing schemas or frameworks.
Equilibration
A mechanism that Piaget proposed to explain how children shift from one stage of thought to the next. The shift occurs as children experience cognitive conflict, or disequilibrium, in trying to understand the world. Eventually, they resolve the conflict and reach a balance, or equilibrium, of thought.
Cognitive Observations
The process of monitoring and analyzing thought processes, including memory, perception, and problem-solving.
