“Our knowledge at the basic level is mainly organized around part-whole divisions. The reason is that the way an object is divided into parts determines many things.
- First, parts are usually correlated with functions, and hence our knowledge about functions is usually associated with knowledge about parts.
- Second, parts determine shape, and hence the way that an object will be perceived and imaged.
- Third, we usually interact with things via their parts, and hence part-whole divisions play a major role in determining what motor programs we can use to interact with an object. Thus, a handle is not just long and thin, but it can be grasped by the human hand.”
