Based on the Fitts Lectures, this volume presents a core set of concepts and principles that proposes a unified interpretation of a wide variety of phenomena of memory, categorization and decision-making. These theories are then applied to issues in category-learning and recognition.

Handbook of Categorization in Cognitive Science, Second Edition presents the study of categories and the process of categorization as viewed through the lens of the founding disciplines of the cognitive sciences, and how the study of categorization has long been at the core of each of these disciplines. The literature on categorization reveals there is a plethora of definitions, theories, models and methods to apprehend this central object of study. The contributions in this handbook reflect this diversity. For example, the notion of category is not uniform across these contributions, and there are multiple definitions of the notion of concept. Furthermore, the study of category and categorization is approached differently within each discipline. For some authors, the categories themselves constitute the object of study, whereas for others, it is the process of categorization, and for others still, it is the technical manipulation of large chunks of information. Finally, yet another contrast has to do with the biological versus artificial nature of agents or categorizers. - Defines notions of category and categorization - Discusses the nature of categories: discrete, vague, or other - Explores the modality effects on categories - Bridges the category divide - calling attention to the bridges that have already been built, and avenues for further cross-fertilization between disciplines

Originally published in 1978, the papers in this book derive from a 1976 meeting sponsored by the Social Science Research Council to discuss the nature and principles of category formation. It is organized in three sections: real-world categories, the cognitive processes underlying categorization, and the nature of representation. Part I examines different structural aspects of real-world categories: folk biological taxonomies, within and between category structures for material objects, and some categories in a language that codes the world in a visual–gestural mode. All three chapters in Part I assume category processors who are able to perform at least three cognitive functions: They can judge similarity between stimuli; they can perceive and process the attributes of a stimulus; and they can learn. Part II presents analyses of these three cognitive functions. All discussion of psychological structures and processes lead eventually to the issue of representation, and Part III examines representational assumptions underlying the earlier discussions. Today it can be read and enjoyed in its historical context.

John Lucy uses original, empirical data to examine the Sapir-Whorf linguistic relativity hypothesis: the proposal that the grammar of the particular language that we speak affects the way we think about reality. The author compares the grammar of American English with that of the Yucatec Maya, an indigenous language spoken in Southeastern Mexico, focusing on differences in the number marking patterns of the two languages. He then identifies distinctive patterns of thought relating to these differences by means of a systematic assessment of memory and classification preferences among speakers of both languages.

A proposal for a categorization of cognition based on core properties of the constituent processes that integrates theory and empirical findings across domains. All sciences need ways to classify the phenomena they investigate; chemistry has the periodic table and biology a taxonomic system for classifying life forms. These classification schemes depend on conceptual coherence, demonstrated correspondences across paradigms. This conceptual coherence has proved elusive in psychology, although recent advances have brought the field to the point at which it is possible to define the type of classificatory system needed. This book proposes a categorization of cognition based on core properties of constituent processes, recognizing correspondences between cognitive processes with similar underlying structure but different surface properties. These correspondences are verified mathematically and shown not to be merely coincidental. The proposed formulation leads to general principles that transcend domains and paradigms and facilitate the interpretation of empirical findings. It covers human and nonhuman cognition and human cognition in all age ranges. Just as the periodic table classifies elements and not compounds, this system classifies relatively basic versions of cognitive tasks but allows for complexity. The book shows that a more integrated, coherent account of cognition would have many benefits. It would reduce the conceptual fragmentation of psychology; offer defined criteria by which to categorize new empirical results; and lead to fruitful hypotheses for the acquisition of higher cognition.

The Folk Classification of Ceramics: A Study of Cognitive Prototypes provides a general understanding of folk classification that compares cognitive structures across cultures through anthropological field studies. The topic of this book, the structure and use of folk categories, is relevant to all cognitive sciences and is distinctly anthropological in examining variation among subcultural groups and change through time. The study of variation and change illuminates aspects of category structure that would not be envisioned from experiment or introspection. This text concentrates on the study of folk classification of artifacts on ceramic vessels, focusing on gross social groupings such as "potters or "traditional villages. Some topics discussed include the exploring interview techniques; structure of vessel categories; subcultural variation; and semantic change. This publication is a good reference to students studying folk classification and other disciplines such as cognitive psychology, linguistic semantics, and artificial intelligence. - Focuses on the process of risk assessment, management and communication, the key to the study of air pollution - Provides the latest information on the technological breakthroughs in environmental engineering since last edition - Updated information on computational and diagnostic and operational tools that have emerged in recent years

A major linguistic study of nominal classification systems across a variety of languages, first published in 2000.
