The relational correspondence between category exemplars and names
- Philosophical Psychology
, 2003
"... ABSTRACT While recognizing the theoretical importance of context, current research has treated naming as though semantic meaning were invariant and the same mapping of category exemplars and names should exist across experimental contexts. An assumed symmetry or bidirectionality in naming behavior h ..."

Typicality in logically defined categories: Exemplar-similarity versus rule instantiation
- Memory & Cognition
, 1991
"... A rule-instantiation model and a similarity-to-exemplars model were contrasted in terms of their predictions of typicality judgments and speeded classificalions-for-members-oflogically defined categories. In Experiment 1, subjects learned a unidimensional rule based on the size of objects. It was as ..."

Attention, similarity, and the identification-Categorization Relationship
, 1986
"... A unified quantitative approach to modeling subjects ' identification and categorization of multidimensional perceptual stimuli is proposed and tested. Two subjects identified and categorized the same set of perceptually confusable stimuli varying on separable dimensions. The identification dat ..."

), assumes that subjects store category exemplars in memory. Classification decisions are based on the similarity of stimuli to the stored exemplars. It is assumed that the same multidimensional perceptual representation underlies performance in both the identification and Categorization paradigms. However
When memory shifts towards more typical category exemplars: Accentuation effects in the recollection of ethnically ambiguous faces
- Journal of Personality and Social Psychology
, 2004
"... In 4 studies, the authors examined the impact of categorization on the recollection of ethnically ambiguous faces. Participants were presented with faces lying at various locations on mixed-race continua (i.e., Caucasian-North African and Caucasian-Asian faces were used as source images in a morphin ..."

Rules and Exemplars in Category Learning

haracterized by descriptions of each module and how each serves in those tasks for which it is best suited. However, these theories often do not emphasize how modules interact in producing responses and in learning. In this article we will develop a modular theory of categorization that follows from two distinct accounts of this behavior. The first account is that of rule-based theories of categorization. These theories emerge from a philosophical tradition in which concepts and categorization are described in terms of definitional rules. For example, if a living thing has a wide, flat tail and constructs dams by cutting down trees with its This work was supported by Indiana University Cognitive Science Program Fellowships and by NIMH ResearchTraining Grant PHS-T32-MH19879-03 to Erickson, and in part by NIMH FIRST Award 1-R29-MH51572-01 to Kruschke.

Is a rose always a rose? The role of social category exemplar change in attitude stability and attitude-behavior consistency

In Experiment l, participants displayed greater attitude stability across 1 month, in several social categories, when they named the same rather than different exemplars.

A standardized set of 260 pictures: Norms for name agreement, image agreement, familiarity, and visual complexity
- JOURNAL OF EXPERIMENTAL PSYCHOLOGY: HUMAN LEARNING AND MEMORY
, 1980

The pictures are black-and-white line drawings executed according to a set of rules that provide consistency of pictorial represent ..."

Sources of naming variance, and mean familiarity and complexity of the exemplars, differed significantly across the set of categories investigated. The potential significance of each
Schema abstraction‖ in a multiple-trace memory model
- Psychological Review
, 1986
"... A simulation model of episodic memory, MINERVA 2, is applied to the learning of concepts, as represented bythe schema-abstraction task. The model assumes that each experience produces a separate memory trace and that knowledge of abstract oncepts i derived from the pool of episodic traces at the tim ..."

The model successfully predicts basic findings from the schema-abstraction literature (.g., differential forgetting of proto-types and old instances, typicality

An exemplar-based random walk model of speeded classification
