This study examined the role of sex and intelligence in the relationship between field dependence-independence and second language acquisition for a sample of 383 students (187 girls and 196 boys) aged between 13 and 16. The Portable Rod and Frame Test (PRFT) and the Embedded Figures Test (EFT) were used to evaluate cognitive style. A two-way covariance analysis, with intelligence as the covariate, was employed to investigate differences in second language achievement between students classified as either field-dependent or field-independent. A cluster analysis using z scores was examined to study the performance of subjects classified as either field-dependent or field-independent according to scores obtained on the EFT and the PRFT (“coincident” subjects) and those classified as field-dependent in one test and field-independent in the other (“non-coincident” subjects). No statistically significant differences between the two groups were obtained when cognitive style was defined by scores on the PRFT. When field dependence-independence was measured by scores on the EFT, field-independent girls performed better than field-dependent girls (p < .005), but this outcome was not observed for boys. These results suggest a differential contribution of the “perceptive” and “cognitive” components of field dependence-independence and a modulating role by sex.
