Average correlations for three age groups from the BAS standardization data were factor
analysed using principal‐factor analysis. Children aged 5: 0–7: 11 years were given 19
scales, those of 8: 0–13: 11 were given 18, and those aged 14: 0–16: 11 were given 14. Two
factors were extracted with eigenvalues> 1 at each age level. The first factor, clearly
identifiable as g, accounted for about 30 per cent of the variance. The second factor, again
clearly identifiable for each age group as verbal recall of pictures, accounted for between 5 …
