Jean Piaget argued that cognitive development is a process of adaptation to one's environment and the many new experiences a person gains from it. Piaget suggested that humans always seek cognitive balance, or harmony between thoughts and the environment, and this is done through two processes: assimilation and accommodation. Assimilation occurs when a person integrates a new experience or stimulus into their already existing patterns. Accommodation, however, occurs when an existing schema no longer works and a person must adjust the schema itself to the new experience (CrashCourse, 2014b). For example, when I was a kid and received my first DVD, I used my existing schematics for a disc and assumed it was a computer game or CD since DVD did not fit into my schema for movies, which included exclusively VHS tapes. I assimilated the DVD into my existing layout and attempted to use the disc accordingly. When that didn't work, I had to adapt my cinematic schema by recognizing the DVD as a copy of a film. Overall, exposure and adaptation to new experiences can help one learn and grow.
