Accommodation

The process of modifying or adjusting an existing scheme or psychological structure in order to act upon or know an object, event, or person.  For example, a child accommodates his grasping scheme when he adjusts his hand movements to fit the contours of a particular object.  In Piaget‘s theory, accommodation must occur in tandem with assimilation in the process of equilibration.
