Abstract
A traditional account for categorization is that similarity
is the main basis of categorizing objects. A recent approach, however,
emphasized the role of deeper features and variability of examples as
additional factors in categorization. The current studies show that
feature weighting differs in categorization and similarity
judgment. Deeper features are operationalized to be the features that
cause surface features. The first experiment shows that, other things
being equal, deeper features are weighted more heavily in similarity
judgments than are surface features. Two further experiments show
that deeper features are weighted more heavily than surface features
in categorization than they are in similarity judgment. Due to this
difference in feature weighting, categorization and similarity can be
dissociated.
