A reparameterization of a latent class model is presented to classify and scale nomial and ordered categorical choice data simultaneously. The model extension represents a nonhomogeneous population as a mixture of homogeneous subpopulations. Simulated data and data from a magazine preference survey of 347 college students illustrate the model.…

Presents a class activity in which student describe and classify music as an introduction to writing classification essays. (SR)

Examines citations to articles in the field of social work to determine citation rates, identify the most highly cited articles, and examine the most frequently addressed topics in two prominent social work journals.

Presents results of a study that explored the effect of overt categorization on musical preference. Found no difference in choices of nonmusic majors when choices were structured as stipulated, unstipulated, or free form categories.

An evaluation was conducted to determine the potential usefulness of the Child Behavior Checklist (CBCL) with 97 children aged 7-17 years living in residential mental health facilities. Comparison with other measures of behavioral functioning suggests the utility of the CBCL for evaluating children in residential placement settings. (SLD)

Two students with moderate to severe mental retardation learned delayed matching to sample in which some of the trials involved complex sample stimuli, each consisting of a picture and a printed word. Matching to either the preceding picture or printed word sample was reinforced. Evidence for the formation of equivalence classes was observed.…

Forty parents of children with autism or pervasive developmental disorder completed the Wing Subgroups Questionnaire, developed for subclassifying children into one of L. Wing's three hypothesized subgroups. Results indicated that the questionnaire has adequate external criterion-referenced validity, with similar subgroup ratings made by…

This study, involving 90 children with mental retardation and epilepsy, classified and compared level of retardation, neurological findings, and electroencephalograms with the quality of seizure control. No correlation was found between quality of control and any of these parameters. (Author/JDD)

Data from 48 infants revealed (1) that infants aged 1;2-2;3 failed to establish a stable word-object link even in follow-in labeling and (2) that only infants aged 1;6-1;7 could identify the correct referent during discrepant labeling. During the period between 1;2-1;7 infants are becoming increasingly adept at acquiring new labels under minimal…

A sample of 74 Finnish children with mild learning disabilities and 57 controls were grouped into 5 subgroups (normal, general language, visuo-motor, general deficiency, naming) and followed from the third to the sixth grade. Results indicated that neuropsychological profiles were generally maintained, with changes related to progress in reading.…

Describes a classification system devised for exercise-associated collapse in endurance events based on casualties observed at six Twin Cities Marathons. Major diagnostic criteria are body temperature and mental status. Management protocol includes fluid and fuel replacement, temperature correction, and leg cramp treatment. (Author/SM)

Most analyses of linguistic errors set up unidimensional categories of grammatical, lexical, and semantic deviations. A two-dimensional classification system is described that formed the basis of a study of phenomena of foreign-language interaction. Thirteen classes of linguistic deviation emerged in the study. (Contains 37 references.) (Author/LB)

Free-recall memory performance of and spontaneous strategy use by 227 field-dependent and field-independent undergraduates were investigated by means of memorized word lists that were high or low in inherent organization and when cognitive strategy instruction was provided or withheld. Results are consistent with current views of field-dependence…

Examined whether expert raters (n=5) could agree about classification of Medical College Admission Test (MCAT) items and whether they agreed with MCAT student manual in labeling skill being measured by each test item. Results revealed difficulties in replicating authors' labeling of skills for reading items on practice test provided with 1991 MCAT…
