Investigated the impact of categorization on confirmatory factor analysis parameter estimates, standard errors, and five ad hoc fit indexes through simulation studies. Results replicate some previous studies but also suggest that tests of parameter estimates will be underestimated and the amount of underestimation will increase as saturation…

Studied whether the characteristics of the optimal categorization identified by Rasch analysis in a previous study could be maintained when the revised scale was applied to the same population (206 members of the original adult sample). Overall, the Rasch model fit well, and similar change patterns were observed in two category statistics provided…

Details a study on 10 French native speaking Williams syndrome (WS) individuals in which gender agreement and assignment were assessed through gender categorization and gender concord. Concludes WS people were not impaired in gender agreement which in the French language relies on syntactic rules or on the extraction of regularities, but…

The role of equivalence class formation in delayed position recognition span performance was examined with three mentally retarded adults. Matching-to-sample training established equivalence classes. In subsequent span tests, subject-produced numeral names led to dramatic increases in span scores. The equivalences provided precursors of verbal…

Describes the work by Silvio Ceccato regarding machine translation systems and procedures, exploring such aspects of his work as functional philosophical approaches to machine translation, notional spheres, correlational analysis, and type classifications. Ceccato envisioned many of the methods that are now being applied in machine translation…

This paper proposes that patterns of proximity data that have been characterized in terms of asymmetric similarity may be alternatively characterized in terms of differential bias. An additive similarity and bias model is reviewed, and it is proposed that biases can be stimulus based as well as response based. (SLD)

Discusses problems of general interest in developmental psychology that can be successfully studied in the domain of food; these include (1) development of food likes and dislikes; (2) establishment of the edible/inedible distinction; (3) disgust and contagion; (4) transgenerational communication of preferences; and (5) transition to food…

To begin formal thinking skills instruction teachers need a plan which consists of a taxonomy of skills, a timetable, and effective teaching techniques. This article presents a condensed version of an existing in-place taxonomy and a scope and sequence timetable which can serve as a guideline for teachers. (IAH)

Describes characteristics of experimental predictor battery of tests developed to supplement the Armed Forces Vocational Aptitude Battery for making selection and classification decisions for entry-level enlisted personnel. Explains procedures used to develop new test battery. Basic psychometric properties of each measure, as determine by large…

Used data from 4,039 job incumbents from 9 military jobs to determine degree of validity generalization across major components of performance and degree of validity generalization across jobs within each major performance factor. Major findings were that different predictor equations were needed for each of 5 criterion factors. (Author/NB)

In 5 experiments, 10 month olds were habituated to exemplars of a form category and tested for categorization in paired-comparison trials involving in-category versus out-of-category stimuli. Results suggest infants' internal representation for category will not include stimulus dimension not varied in exemplars from which the category was…

Taxonomies are unavoidably infused with recommendations of what ought or ought not to be. Thus, use of descriptive taxonomies may have a normatively conservative effect independent of user intentions. The importance of taxonomies to adult education necessitates a critical understanding of their normative features. (SK)

Proposes a taxonomy of moral values to be used by researchers in developing unbiased instruments for assessing the nature of people's moral reasoning. Discusses six ways of defining "moral" and selects one as a means of illustrating the use of the proposed taxonomy in constructing such an instrument. (KO)

The mechanisms of both language-based and non-language-based learning disabilities are presented within the framework of central nervous system development and the compromises to that development that arise from genetic, hormonal, antibody, medication, and postnatal compromises. Also reviewed is the need for a taxonomy of learning disabilities.…

Investigation into the relative effectiveness of four input strategies for two-year-olds' (N=56) category evolution found that the most effective strategy involved labelling an object and providing both a physical demonstration and a verbal description of important attributes. (Author/CB)
