necessarily indicate that the two language versions (English and Xhosa) of the Griffiths<br />

Scales are not equivalent. Culture must be considered to be a confounding variable in any<br />

study of the effect of language on test performance. Another aspect which could explain the<br />

significant difference on the Hearing and Speech Scale is the influence of the experiential<br />

world of the young urban child on test scores. Earlier research indicated that Black African<br />

children did not feel at home with pictorial representations (Biesheuvel, 1949; Minde &<br />

Kantor, 1976). Furthermore, it is possible that the children from different cultural and social<br />

groups were not equally familiar with some of the test items, which in turn affected their test<br />

performance. Allan (1992) stated that although the White and Black children were very<br />

similar in terms of parental education and occupational levels, Duminy (1973) proposed that<br />

the environment in which the Black child lives, is completely different from that of his White<br />

counterpart. Therefore, it is possible that the significant difference between White and Black<br />

children is due to cultural and environmental factors, rather than the language of the<br />

translation as such (Allan, 1992).<br />

In comparison with the British standardization sample, a significant difference was<br />

obtained for White children who scored significantly higher with respect to the GQ, the<br />

Hearing and Speech Scale (CQ) and Practical Reasoning Scale (FQ).<br />

Regarding the analyses of individual items, the items of each individual scale of the<br />

Griffiths Scales are arranged in order of difficulty (Griffiths, 1984). A decreasing trend was<br />

found in the percentage of 5-and 6-year-old children from each cultural group, who passed<br />

successive items of the individual scales. For the 5-year-olds from the British<br />

standardization sample and each of the South African cultural groups, the percentage of<br />

children who passed successive items of the individual scales was correlated. This was<br />

done for every individual scale. Allan’s (1992) study indicated that item bias may hinder a<br />

national multicultural standardization of the Griffiths Scales for South African children. The<br />

present British norms are furthermore not applicable for South African Indian and White<br />

children, but appear to be more applicable for South African Black and Coloured children.<br />

Bhamjee (1991) completed a study which investigated the applicability of the Griffiths<br />

Scales for South African Indian children. The sample (N = 360) consisted of children<br />

between the ages 3 years and 8 years, with equal numbers of each gender group. The<br />

differences were most significant in the pre-school age group. The results of the study<br />

indicated that the South African Indian children performed significantly higher than their<br />
