Following an extensive review of the literature, this study explores the relationship between L2 achievement and two learner characteristics -field dependence-independence and hemisphericity. Sixty-nine Turkish students of 11 to 12 years of age in an intensive EFL programme were administered the GEFT, the CLEM, and tests of L2 achievement. Significant positive correlations were observed between the GEFT scores and scores on L2 achievement tests. As expected, field independent learners performed better on the discretepoint and cloze tests. Hemisphericity, however, was not found to be related to L2 achievement. These results are evaluated critically and their implications for further research are discussed.One of the factors which accounts for differences in the manner students learn concerns the area of cognitive styles. Cognitive styles can be defined as the specific and relatively stable ways in which learners perceive and approach mental tasks. As such, they refer to an individual's preferred perceptual and intellectual mode. Hartnett (1980) classifies learners into two major categories with respect to the various dimensions of cognitive style that have been identified. The first group is said to be field independent, verbal, analytic, serialist, and sequential-successive. In contrast, the second group is described as field dependent, imaginal, relational, holist, and simultaneous-synthetic. Hartnett refers to the cognitive modes of the former group as 'analytical' and to those of the latter as 'holistic'.L2 learners are no exception to the above generalizations. Some prefer to use a more analytic approach to second language learning problems, while others prefer to tackle them in a predominantly holistic manner. However, learners' relatively stable preferences in this regard do not imply that there exist two distinct types of human beings. What is instead at issue here is a person's tendency to rely on a particular cognitive style more than the other. Otherwise, individuals are known to make use of varying degrees of analytic and
