Within the field of school psychology, the currently accepted structure of intelligence is the Cattell-Horn-Carroll Model (CHC). The CHC model contains three strata of abilities: a general ability (g), multiple broad cognitive abilities, and several narrow abilities (Schneider & McGrew, 2018), although the theoretical salience of the g factor…

The measurement of perfectionistic cognitions has recently caused disagreement among researchers. Flett, Hewitt, Blankstein, and Gray proposed that perfectionistic cognitions are unidimensional. However, after re-examining the factor structure of the instrument used to measure perfectionistic automatic thoughts (Perfectionism Cognitions Inventory…

In the current article, we describe the development and validation of the Mistake Rumination Scale as a supplement to existing trait and cognitive measures of perfectionism. The Mistake Rumination Scale is a seven-item inventory that taps the tendency to ruminate about a past personal mistake. Psychometric analyses confirmed that the Mistake…

Fluency is an important construct in clinical assessment and in cognitive taxonomies. In the Cattell-Horn-Carroll (CHC) model, Fluency is represented by several narrow factors that form a subset of the long-term memory encoding and retrieval (Glr) broad factor. The CHC broad classification of Fluency was evaluated in five data sets, and the CHC…

The purpose of the present study was to adapt and validate the Need for Cognition Scale--Short Form (NfC-SF) in the Greek language. A multistep process was followed, including (a) the translation and adaptation of the questionnaire, (b) a reliability analysis of the instrument's items in combination with an exploratory factor analysis with 177…

Using multitrait, multimethod data, and confirmatory factor analysis, the current study examined the effects of arithmetic item formatting and the possibility that across formats, abilities other than arithmetic may contribute to children's answers. Measurement hypotheses were guided by several leading theories of arithmetic cognition. With a…

The Wechsler Adult Intelligence Scale (WAIS) and 20 tests from the French Kit were administered to over 100 undergraduates. Analyses revealed ten factors: verbal comprehension, visualization, memory span, syllogistic reasoning, general reasoning, induction, mechanical knowledge, number facility, spatial orientation, and associative memory.…

For a group of 165 fourth- and fifth-grade students, four achievement test scores were correlated with success on nine tests designed to measure three cognitive functions: sustained attention, successive processing, and simultaneous processing. This experiment was designed in accordance with Luria's model of the three functional units of the…

This study examined whether a timesharing factor can be identified when a number of competing tasks are presented in the midst of a range of single tests designed to sample a broad range of psychological dimensions. A battery of single and competing tasks was presented to 126 subjects. (Author/LMO)

Piaget has hypothesized that concrete and formal operations can be described by specific logical models. The present study focused on assessing various aspects of four concrete operational groupings and two variations of two formal operational characteristics. Six hundred twenty-two 9-14 year old students participating in the Human Sciences…

The primary objectives of this project commonly refereed to as "Assessing Human Abilities" were: (1) to provide reference measures for cognitive factors; and (2) to provide a guide to reference measures for self-report temperament factors. The overall objective was to conduct research in the area of factor analysis directed toward the…

Twenty-six test variables for psychological differentiation and cognitive abilities were factor analyzed with a view towards replication of certain factors of perceptual and conceptual differentiation and related these factors to cognitive abilities. (Author)

Results from correlated multiple-group component analyses of the Revised Illinois Test of Psycholinguistic Abilities (ITPA) subtests were given. Intercorrelations for each age group in the standardization sample provided strong support for the theoretical model underlying the Revised ITPA. (Author/MH)

Relationships among Piagetian reasoning assessments and standard measures of intelligence and achievement were determined in 1972 by Stephens, McLaughlin, Miller, and Glass (EJ 055 112). The data were reanalyzed by Humphreys and Parsons in 1979 (EJ 218 642). In reply, Glass and Stephens note fallacies in Humphreys' and Parsons' reasoning.…

The historical development and recent applications are described of the picture sequencing format (PSF), a testing device which requires the subject to designate a complete and correct order for a set of related pictures. The earliest use was by Decroly in 1914 and perhaps the best known use is in the Wechsler intelligence tests. Special…
