Examined the relationship of the Minnesota Multiphasic Personality Inventory high-point codes and the diagnostic system of the Diagnostic Statistical Manual III. Identified 24 code types from a private psychiatric clinic sample (N=261). Presented the resulting clusters of diagnostic classification and a narrative summation for each code type.…

In a classification task, preschoolers matched a target stimulus with a conventional category, a visually similar item that cut across conventional categories, or an unrelated item. Items were presented in picture, verbal, and picture-verbal conditions. In all conditions, conventional classifications outnumbered visual ones, and this difference…

The neuropsychological approach to studying learning disabilities (LD) has produced two extreme positions: the view of LD as (1) homogeneous and unitary and (2) as a pattern of unique and idiosyncratic characteristics. Resulting classification approaches for determining subtypes of the population have important implications for assessment and…

The study compared the categorization skills of first-grade children presenting three levels of expressive language development (normal, mild-moderate delay, and severe delay). Results indicated a significant difference in categorization skills between the children with normal expressive language development and each of the two expressive…

Reviewed are some of the environmental periodical literature available to the public. The periodicals are divided into three categories: periodicals that deal chiefly with environmental problems and research, periodicals that are generally classified as conservation and nature magazines, and periodicals from other fields that include material on…

Discusses the problems of devising chemical names that permit the construction of a structural representation from a substance name. (MLH)

A measure for the quantification of the changes in classification under small changes in data is proposed. (Author)

This paper describes and evaluates the use of decision theory as a tool for classifying examinees based on their item response patterns. Decision theory, developed by A. Wald (1947) and now widely used in engineering, agriculture, and computing, provides a simple model for the analysis of categorical data. Measurement decision theory requires only…

In a conceptual-analytical study using a deductive classificatory content analysis method ten constructivist instructional design models were selected, and learning/teaching approaches within each model were appraised. Using the original writings of the originators of each design model, the learning and teaching approaches employed or permitted to…

This paper proposes a new typology for understanding common research errors that expands on the four types of error commonly discussed in the research literature. Examples are presented to illustrate Type I and Type II errors, errors related to the interpretation of statistically significant and nonsignificant results respectively, with attention…

The article's thesis is that evolution's intellectual foundations have been steadily eroding, and that few new findings in embryology, taxonomy, fossil remains, and molecular biology are bringing us very near to a formal, logical disproof of Darwinian claims. The paper begins by discussing the evidence of a prehistoric world, then they discuss…

This volume is an attempt to articulate a taxonomy of educational objectives that uses the best available research and theory accumulated since the publication of the taxonomy of educational objectives of B. Bloom and others in 1956. Like Bloom's taxonomy, this taxonomy defines six levels of mental processing: self-system thinking (Level 6);…

This paper discusses a well-known problem of stage categorization within Kohlberg's theory of moral stages (L. Kohlberg, 1973), that of "Stage 4 1/2." Some subjects previously scored at stage 4 in Kohlberg's framework took on some characteristics of stage 2 reasoning, which suggested the possibility of regression. To reconcile this…

A study was conducted to explore the factors that have impact on the individual freedom and autonomy of academics in the changing university climate. Through the development of an ideal typology of educational researchers, based on the work of Max Weber, the study reveals the ways in which individuals within these changing institutions make…

This paper describes a class of rater effects that depict rater-by-time interactions. This class of rater effects is referred to as differential rater functioning over time (DRIFT). This article describes several types of DRIFT (primacy/recency, differential centrality/extremism, and practice/fatigue) and Rasch measurement procedures designed to…
