Samenvatting
It was found that an object can be categorized faster at the basic level than at either a subordinate or a superordinate level. This result was attributed to basic categories having more distinctive attributes. But numerous factors other than the number of distinctive attributes might have caused this result. In this paper three experiments are reported all of which used artificial subordinate, basic and superordinate categories and all of which either held constant or systematically varied several of these factors.
