✦ Synopsis

The factor structures of the WISC and WISC-R were secured for a group of Polish fourth-grade students (N = 30). Consistent with American findings, the WISC Verbal, Performance, and Full Scale IQs were higher than those on the WISC-R. On both measures, factor results favor the two-factor solution, which approximates Wechsler's Verbal and Performance scales. A third factor, which failed to simulate Freedom from Distractibility, accounted for approximately 10% of the explained variance. On this factor, Coding was heavily weighted, but Arithmetic and Digit Span loadings ranged from modest to negative. Results provide support for the application of the Wechsler instruments in cross-cultural settings and for interpreting the third factor according to the dynamics of specific cultures.
