Hypothetical model of category representation in terms of semantic attributes illustrates typical examples represented at the center of semantic space and atypical examples represented at the periphery of this space. The center of this space represents the core of the category and surrounding it are the prototypical features. Typical examples (e.g., robin, sparrow) primarily consist of prototypical features whereas atypical examples (e.g., penguin, ostrich) primarily consist of distinctive features.
