Example of Assimilation and Accommodation in Schema Development

A toddler has a mental framework for 'ball' that includes anything round. He sees an orange for the first time and calls it a 'ball'. His mother corrects him, explaining that it's a fruit you can eat. After this experience, the toddler's mental framework for 'ball' is refined to mean something round that you play with, and he creates a new framework for 'fruit'. Which cognitive process does this adjustment of his mental framework best illustrate?

A toddler has developed a mental category for 'ball', believing it refers to any round object. When the toddler sees an orange for the first time, they point and say 'ball'. After their parent explains that it's a fruit you can eat, the toddler's understanding changes. They now have a more refined category for 'ball' (something you play with) and a new category for 'orange' (something you eat). Which cognitive process does this change in the toddler's mental categories best illustrate?
