- Description: The Raven’s Coloured Progressive Matrices (CPM) test is used extensively across a wide variety of settings in South Africa, however more appropriate local normative data has yet to be established. The CPM is internationally recognised as a culture-fair test of nonverbal intelligence, designed for use with children between the ages of 5½ and 11½. This pilot study thus sought to establish normative data for this instrument for a population of Xhosa-speaking Primary School children in the peri-urban township area in the Grahamstown region. The booklet version of the test was used and it was administered in group format and according to an alternate method of test administration (using Xhosa instructions) developed by Vass in 1992. The final normative sample consisted of 197 male and 182 female Xhosa-speaking children in Grades Two to Seven (N=379). The results showed (1) a significant effect of age on test scores, where scores increased with age as expected; (2) a consistent tendency for males to outperform females was also noted, however small sample sizes precluded any categorical claims to this effect; (3) no significant effect of education on test scores was observed and finally; (4) and finally, it appeared that the norms generated for this study revealed a tendency to be lower than those obtained by Raven, Court and Raven (1990) during the standardisation of this instrument in the United Kingdom and America. The study concluded that (1) there is an urgent need for more appropriate South African normative data for this test; and (2) that when assessing African children from disadvantaged backgrounds, further research into the effects of cultural and socio-economic factors and gender on non-verbal intelligence (and on performance on this test in particular) is required.

- Description: The purpose of this study was to compare the WISC-R subtest score scatter patterns and obtain preliminary normative data on the WISC-R Adjunctive tests (Digit Span Forward; Digit Span Backward; Digit Supraspan; Coding Immediate Recall and Coding Delayed Recall) on a non-clinical population of South African English (n= 15) and Xhosa (n= 12) speaking, standard six children, studying in English medium schools. Tests were administered to 27 subjects, both male (n=19) and female (n=8), with a mean age of 14.1 years (range = 13.3-15.3). The results show that White English speaking children outperform Black Xhosa speaking children on Verbal, Performance and Full Scale IQs and all subtests, but that these differences tended to disappear when Full Scale IQ and school grade average were controlled for. No subtest score scatter was present for either group although more specific test items appeared to be more difficult for Xhosa speaking subjects and may have contributed to generally lowered scores. Results suggest that caution must be employed in assigning Xhosa speaking South African children to absolute IQ categories. However, the WISC-R has validity for diagnostic use on both White English speaking and Black Xhosa speaking South African children as there was no evidence of a significant Verbal IQ/Performance IQ discrepancy, or significant low subtest scatter for either group. Normative tables are presented for the use of WISC-R Adjunctive tests. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in
