In 3 experiments, the authors tested performance in simple tone matching and classification tasks. Each tone was defined on location and frequency dimensions. In the first 2 experiments, participants completed a same-different matching task on the basis of one of these dimensions while attempting to ignore irrelevant variation in the other…

Forty participants assigned artificial creatures to categories after explicit rule instruction or feedback alone. Stimuli were typical and atypical exemplars of 2 categories with independent prototypes, conflicting exemplars sharing features of both categories, and "Others" with only 1 or 2 features of the well-defined categories. Ten…

J. P. Minda and J. D. Smith (2001) showed that a prototype model outperforms an exemplar model, especially in larger categories or categories that contained more complex stimuli. R. M. Nosofsky and S. R. Zaki (2002) showed that an exemplar model with a response-scaling mechanism outperforms a prototype model. The authors of the current study…

Speeded perceptual classification experiments were conducted to distinguish among the predictions of exemplar-retrieval, decision-boundary, and prototype models. The key manipulation was that across conditions, individual stimuli received either probabilistic or deterministic category feedback. Regardless of the probabilistic feedback, however, an…

In naming artifacts, do young children infer and reason about the intended functions of the objects? Participants between the ages of 2 and 4 years were shown two kinds of objects derived from familiar categories. One kind was damaged so as to undermine its usual function. The other kind was also dysfunctional, but made so by adding features that…

Relational similarity connects superficially dissimilar objects and events. In 2 experiments, the ability to recognize and respond to similar relations was studied in children ages 3 to 5 with 2 comparison tasks. Children interpreted illustrated pictures that shared perceptual or relational aspects and then made 2 comparison choices and…

This study tests the firm distinction children are said to make between living and nonliving kinds. Three, 4-, and 5-year-old children and adults reasoned about whether items that varied on 3 dimensions (alive, face, behavior) had a range of properties (biological, psychological, perceptual, artifact, novel, proper names). Findings demonstrate…

A biologically detailed computational model is described of how categorization judgments become automatic in tasks that depend on procedural learning. The model assumes 2 neural pathways from sensory association cortex to the premotor area that mediates response selection. A longer and slower path projects to the premotor area via the striatum,…

Historically, accounts of object representation and perceived similarity have focused on intrinsic features. Although more recent accounts have explored how objects, scenes, and situations containing common relational structures come to be perceived as similar, less is known about how the perceived similarity of parts or objects embedded within…

This paper presents cognitive strategies as one major approach to pain management. They are discussed as part of a trimodal system of pain management that also includes behavioral manipulations and physical intervention. The need for a standardized classification to deal with terminological inconsistency in the literature on cognitive management…

In free recall learning, taxonomic organization has been studied almost to the exclusion of alternative types of organization. Consequently, little is known about how learning and memory are affected by alternative types of organizations. The present experiments explored the differential effects of two kinds of organization on free recall…

This report, a supplement to Technical Report Number 82, is designed to aid the researcher concerned with concept learning. It contains: (1) a rationale and strategy for compiling a bibliography of articles concerned with concept learning; (2) a definition of the word concept; (3) a system for classifying articles by their content; (4) a…

A need exists for a more clear-cut description of how the taxonomy of educational objectives can be implemented in the school setting. In answer to that need, a way is shown to formulate specific behavioral objectives within the hierarchy of the major levels and sublevels of the taxonomies as set forth by Bloom (1956) and Krathwohl (1964). To…
