This study compared the ICD-10 criteria for Asperger syndrome with those suggested by Gillberg with 200 children and adults who met ICD-10 criteria for autism. Comparison indicated only three subjects met ICD-10 criteria for Asperger syndrome whereas 91 met Gillberg's criteria. The discrepancy appeared due to the specific "normal development"…

Explains the new Carnegie classification system for institutions of higher education, a sweeping revision that emphasizes teaching, focusing on the number and types of degrees an institution awards rather than research or selectivity in admissions. The biggest change is for universities that award doctorates--these are now grouped into only two…

Three experiments assessed the claim that preschoolers override form class cues in the interest of honoring word- meaning assumptions when acquiring new labels. Results demonstrated that children respected the form class cues when these cues and word-meaning assumptions suggested conflicting interpretations. It was suggested that past findings…

Examined the classification agreement of risk status across alternative behavior rating methods for 80 preschool children and their teachers and studied target behavior selection. Compared the Social Skills Rating System (F. Gresham and S. Elliott, 1990) to a structured teacher interview. Overall, classification agreement in each comparison was…

Identifies typology of substance users from a sample of 1,580 St. Louis arrestees surveyed through the Arrestee Drug Abuse Monitoring Program. Analyses illustrated that drug-using classifications differ between criminal and non-criminal populations, but that arrestee populations vary interjurisdictionally. Assesses implications for local and…

Calls into question the validity and usefulness of classifying poor readers into learning disability and nonlearning disability categories on the basis of the discrepancy between their IQs and reading achievement scores. A review of the research indicates that the premises on which this classification rests are not valid. (SLD)

Rough set theory is a new mathematical tool to deal with vagueness and uncertainty. Computational methods are presented for using rough sets to identify classes in datasets, finding dependencies in relations, and discovering rules which are hidden in databases. The methods are illustrated with a running example from a database of car test results.…

Develops and analyzes four algorithms for feature selection in the context of rough set methodology. Experimental results confirm the expected relationship between the time complexity of these algorithms and the classification accuracy of the resulting upper classifiers. When compared, results of upper classifiers perform better than lower…

Reacts to Waldo and Bauman's Goals and Process (GAP) matrix for groups article in terms of its usefulness to student-development educators leading psychoeducational groups. Briefly describes the context within which student-development educators do psychoeducational group work. Provides a perspective on applying the proposed matrix and discusses…

Examines philosophical and epistemological perspectives on definitions of competence and its measurement in workplace contexts. Concludes that consensus on parameters and definitions of competence are needed to ensure the clarity, consistency, and reliability of measurement. (Contains 115 references.) (SK)

Describes empirical investigations of people's use of relevance criteria. Highlights include a laboratory experiment and a naturalistic study that explored the patterns of movement in use of relevance criteria during real-time document evaluation processes; criteria patterns; and a classification scheme and criteria taxonomy that may enable…

This study investigated the relationship between categorical perception and dyslexia by comparing the discrimination responses of 19 children with dyslexia and 17 average readers to sinewave analogues of speech sounds presented as either nonspeech whistles or as speech sounds. The study found an increased perceptibility of within-category…

Three studies explored 2- to 4-year-olds' ability to categorize objects based on novel underlying causal power. Children saw that a "blicket" would set off a machine and participated in categorization, induction, and association tasks. Results demonstrated that even 2-year-olds easily learn about an object's new causal power and…

Discusses levels of the Functional Independence Measure (FIM) as ordinal categories. Presents guidelines developed through the Rasch model that prompt an analyst to investigate whether rating categories produce observations on which meaningful measurement and inference about patient status can be based. (SLD)

Preliminary findings from a longitudinal study of 32 preschool children who stutter and 32 nonstuttering controls reveal 4 subgroups: (1) persistent stuttering; (2) late recovery; (3) early recovery; and (4) control. Comparative data for the groups regarding frequency of disfluency, acoustic features, phonologic skills, language development,…
