| Abstract: | Samples of impoverished Zulu schoolchildren drawn from three age groups were tested repeatedly on the Figural Intersection Test (FIT), a measure of M-power in Pascual-Leone's theory of constructive operators. Results showed an initial underperformance when compared with Canadian and urban Zulu children. This was attributed to the effects of impoverishment. However, impoverished children did acquire the age-related levels of performance after repeated trials, a result consistent with the concept of M-power in the theory of constructive operators. |
