Document Summary
With both prototypes and exemplars, judgments of category membership and judgments. This is because both judgments should be based in resemblance between the test case and of typicality should go hand in hand. the prototype or exemplar. However, one problem with the viewpoint we have been describing is that typicality and category membership sometimes dissociate. Moby dick was not a typical whale but was still nevertheless a whale. For instance, participants will rate some odd numbers as being better examples than others, even though they also consider all odd numbers to fit this well-defined category (armstrong et al. , 1983). Some cases that do not have typical features are accepted as category members: E. g. , a lemon that is painted with red and white stripes, injected with sugar to make it sweet, and then run over with a truck, is still a lemon.
