Field dependence-independence was originally conceived as a neutral style dimension, in that field-dependent subjects were considered to be as well-adapted to their environment as field--independent subjects. Subsequent authors, however, questioned this assumption ofneutrality, on the grounds thatfield-independent subjects generally perform better in certain intellectual tasks. Such findings provoked interest in the possible repercussions offield dependenceindependencefor education. Here, we review research into the possible effects of FDI on achievement at school. In general, field-independent subjects perform better than field-dependent subjects, whether assessment is of specific disciplines or across the board. We discuss possible explanationsfor this difference in performance.The earliest research into cognitive styles was carried out by members of the "New Look" movement, a group of psychologists who were concerned that traditional models of perception placed insufficient emphasis on the individual. In the course of research into the contribution o:fvisual and postural cues to perception of the vertical, Asch (1948a, 1948b) found that some subjects consistently tended to use only one or another type of cue. Subjects who used visual cues were designated "field-dependent", while those who used postural (i.e., vestibular, tactile and kinesthetic) cues were designated "field-independent". In its earliest formulation, field dependence-independence (FDI) was conceived as a visual--postural dimension specifically relating to perception of the vertical.More general interpretations were soon to follow. The task developed by Witkin began to be viewed as a measure of the subject's ability to perceive individual elements within an organized perceptual field: according to this point of view, field-independent subjects are those with a greater capacity to break perceptual information down into its component parts and to focus attention on those parts which are relevant, without being distracted by the context. In contrast, field-dependent subjects are those with a greater difficulty to disembed parts from This review was supported by a grant from the Xunta de Galicia, XUGA 21106A91.
