ABSTRACT
Two studies are reported concerning performance differences and similarities across cultures. Pascual-Leone's tests of mental attention/energy (M-power) were administered to Zulu-speaking township children aged from 7 to 12 years. In study 1, the Compound Stimulus Visual Information task (CSVI) was used to determine whether children (N=292) performed at theoretically predicted levels previously obtained with middle-class Canadian children. In study 2, the children (N=252) were required to complete the Figural Intersection Test (FIT) four times. Unlike the CSVI, in which learning is controlled by training prior to testing, the FIT assumes basic familiarity with the general test requirements. The purpose of repeated testing was to assess the extent of learning across trials. The results for study 1 indicate that subjects do perform at the predicted levels on the CSVI and have the same M-power as Canadian children. The results for study 2 indicate that the subjects underperform on trial 1 of the FIT but overperform on trial 2 relative to Canadian children.
