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,…

Have the winter doldrums left your students wistful for summer? Why not initiate a seashell classification activity to rekindle their interest in science and learning! Children love to handle and examine shells at any time of the year--with these favorite nature objects, you often can't get kids to stop talking and sharing their observations about…

This paper synthesizes two perspectives on essentialism: cognitive and social. The cognitive essentialist perspective argues that our bias to appeal to the psychological belief that categories have innate essences enables us to make inferences about social categories such as race, caste, and gender. The social essentialist perspective argues that…

A taxometric analysis of the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) was performed on a group of 2,250 male and female forensic/psychiatric patients and jail/prison inmates. The 4 PCL:SV facet scores (Interpersonal, Affective, Impulsive Lifestyle, Antisocial Behavior) served as indicators in…

This paper explores the concept of the categorisation of social groups by looking at the issue of ascribed categories of identity for children and young people of mixed parentage. Our exploration of the knowledge-base in this area reveals that children and young people have clearly expressed views about their racial identity and that these views…

There have been five major types of correctional education organizations over the centuries: Sabbath school, traditional or decentralized, bureau, correctional school district (CSD), and integral education. The middle three are modern organizational patterns that can be implemented throughout a system: Decentralized, bureau, and CSD. The…

Will multiracial identification resonate with future generations? Using the 2000 U.S. Census, I analyze the impact of a multiracial parent on the classification of children in four types of multiracial families (e.g., white/non-white, black/non-black). Compared to families where parents are of two different single-race backgrounds, parental…

To gain meaningful access to the curriculum, students with reading difficulties must overcome substantial barriers imposed by the printed materials they are asked to read. Technology can assist students to overcome these challenges by enabling a shift from printed text to electronic text. By electronic text it means textual material read using a…

Fuzzy trace theory explains why children do not have to use rules of logic or premise information to infer transitive relationships. Instead, memory of the premises and performance on transitivity tasks is explained by a verbatim ability and a gist ability. Until recently, the processes involved in transitive reasoning and memory of the premises…

Introducing cataloging students, beginning catalogers, copy catalogers, and department administrators to the principles of cataloging, classification, and indexing, this revised text provides a simple, solid foundation for standard practices of cataloging and bibliographic control in the United States and Canada. The book reviews major…

This paper discusses the career of Henry Evelyn Bliss, founder of the Bibliographic Classification, which is currently being revised. Dissatisfied with the current classification systems, Bliss devised his own, which was based on a main class order that provided for collocation of related classes. Although not currently used in the United States,…

This paper describes a four-dimensional model for the science of knowledge acquisition and a classification system in terms of these dimensions. A summary of the state of the art in terms of the cells generated in a four-dimensional representation of this classification system is presented. The need for better tools for conducting knowledge…

Previous research has shown that 3- to 4-month-old infants form a global categorical representation for cats that includes female lions, whereas 6- to 7-month-old infants differentiate between cats and lions. Three experiments using familiarization-novelty preference procedures attempted to determine whether the differentiation of a global…

The importance of man's relationship to time has been widely recognized in psychology. However, ideas about how the subject should be defined and studied have varied greatly. To explore the phenomenological "experience of time", 20 white, middle class, mature, articulate adults (10 male, 10 female) participated in 1-hour semi-structured,…

Infants' responses to male and female faces and their preferences for happy versus fearful faces were studied to extend findings indicating that infants at 7 months can generalize discrimination between expressions of happiness and surprise across four different female models' faces. In the first experiment, a paired-comparison procedure was used…
