Neurophysiological evidence is described showing that some neurons in the macaque inferior temporal visual cortex have responses that are invariant with respect to the position, size and view of faces and objects, and that these neurons show rapid processing and rapid learning. Which face or object is present is encoded using a distributed…

Stuttering characteristics, assessment, and treatment principles present challenges to assessment and treatment that can be addressed with virtual reality (VR) technology. This article describes how VR can be used to assist clinicians in meeting some of these challenges with adults who stutter. A review of current VR research at the Stuttering…

Cross-sectional and longitudinal data from students as they advance through the middle school years (grades 6-8) reveal insights into the development of students' pattern generalization abilities. As expected, students show a preference for lower-level tasks such as "reading the data," over more distant predictions and generation of abstractions.…

This study examined the extent to which ethnic-based differences exist in teacher ratings of African American students and White students on the language and literacy domain of a curriculum-embedded performance assessment for students in grade 1. It extended previous research on performance assessments to focus on issues related to equity in…

In the last decade, several attempts have been made to relate item response theory (IRT) models to latent class analysis (LCA) models. One of these attempts is the solution-error response-error (SERS) model, an LCA model in which the structure of the latent class probabilities is explained by a one-dimensional loglinear Rasch model. In this paper,…

This study investigated the possibility that certain contextual factors and subject variables influence children's deployment of self-protective skills in unsafe social situations. Contextual factors included characteristics of the antagonist in the situation and the nature of the social dilemma. Subject variables included characteristics of the…

A discussion focusing on the abstractness of analysis in phonology, debated since the 1960s, describes the issue, reviews the literature on the subject, cites specific natural language examples, and examines the extent to which the issue has been resolved. An underlying representation is said to be abstract if it is different from the derived one,…

Cultural context is not the sole source of human knowledge. Postmodern theory, in both its deconstructionist and affirmative approaches, offers an incomplete basis by which to study race, class, and gender, and undermines ethical interaction. Deconstructionism calls for the abandonment of generalizable research findings, asserting that the concept…

Two studies investigated the effects of verbalization of discovered generalizations on the retention of those principles. (SD)

An evaluation of selective generalization of habituation on the basis of meaningful categories of stimuli. Also explored are the sex differences in conceptual generalization of habituation. Subjects were 36 toddlers with a mean age of 40 months. (SDH)

During the 1960s and early 1970s two educational movements were the evolution of the middle school and the structures of disciplines approach to social studies. These movements involved school organization, curriculum development, and methodologies incorporating the inquiry or conceptual approach. Learners had trouble with the conceptual approach,…

Preliminary evidence indicates that children begin to generalize knowledge in a new way at approximately 3 years of age. Forty children between 1.5 and 3.5 years of age were given two tasks of graded complexity. The first and simpler task used four nonoverlapping classes, each composed of four identical objects. Two of the classes were tagged with…

Examined were the relationships of children's (1) negotiation of play context and (2) enactment of pretend episodes to (3) children's social adjustment, social acceptance and social cognition. It was predicted that negotiation and enactment of pretend play would be relatively independent, and that enactment would be strongly related to indices of…

A three-factor model for the management of early childhood stuttering is proposed that takes into account stuttering's psychosocial, psycholinguistic, and physiological aspects. The primary focus of the present article is the psycholinguistic factor. To this end, a rationale for the use of language-based therapy is presented, together with…

A school psychologist implemented a practicum designed to increase the prosocial behaviors of children attending a preschool center that integrated handicapped (N=26) and nonhandicapped (N=22) children. Observations had indicated that many of the children at the center were unable to work and play with others without hitting and getting hurt in…
