TLDR
Factor matrix comparisons across age groups resulted in a mean similarity coefficient of .75, which supports the hypothesis of a three-factor structure rather than a four-factor solution or a simple dual classification into items which can be solved by perceptual processes and those which require conceptual solutions.Abstract:
The Raven Coloured Progressive Matrices were administered on group or individual bases to children ranging in age from 4 yr. 9 mo. to 11 yr. 0 mo. (N = 728). Factor analysis yielded three factors: 1. Perceptual closure involving complex figures and patterns with heterogeneous inner structures, 2. Concrete and abstract reasoning, 3. Completion of homogeneous patterns and recognition of given elements. Factor matrix comparisons across age groups resulted in a mean similarity coefficient of .75. Comparisons of data with earlier analyses also resulted in high similarity. This supports the hypothesis of a three-factor structure rather than a four-factor solution or a simple dual classification into items which can be solved by perceptual processes and those which require conceptual solutions.read more

TL;DR: Children with FXS are severely mentally retarded and have a high rate of mainly externalising disorders, and families with mentally retarded children are in even greater need of help than those of children with severe chronic illness/physical handicap.

Components of item difficulty of Raven's matrices
TL;DR: In this article, the authors identify and test item characteristics that predict the difficulty of items on Raven's Colored Matrices (CPM; 1965) and items on SPM (SPM; 1965).

Symptom dimensions in old-age schizophrenics. Relationship to neuropsychological and motor abnormalities.
TL;DR: In this paper, the authors investigated symptomatological dimensions in old age and clarified whether the dimensions correlate differently with neuropsychological and motor parameters in chronic, old-age schizophrenics.

Structural Properties of Raven's Coloured Progressive Matrices for a Sample of Gifted Children
TL;DR: In this article, the results of a Rasch and a factor analysis of Raven's Coloured Progressive Matrices items for a sample of 166 gifted children were investigated and found that of 36 items, 33 had adequate fit to the Rasch model.

The Factorial Structure of the Raven Coloured Progressive Matrices Test
TL;DR: The Raven Coloured Progressive Matrices Test was administered to 180 first, second, and third grade children as mentioned in this paper, and factor analysis revealed three orthogonal factors: concrete and abstract reasoning, continuous and discrete pattern completion, and pattern completion through closure.

TL;DR: Based on data from 783 primary-grade children, results of component factor analyses of the Raven Coloured Progressive Matrices indicated that phi/phi max coefficients and tetrachoric correlation coefficients yielded identical factor patterns that were not affected by item difficulty.
