This study investigated the nature of field independence by exploring the structure underlying responses to Forms A and B of a multiple-choice measure of field-independence, the Finding Embedded Figures Test (FEFT). Subjects included 302 students (52.7% male) enrolled in mathematics courses at a university in the southern United States. Students completed both forms of the FEFT (each form contained 35 items) or one form of the FEFT and the Group Embedded Figures Test, with different orders of test administration. A total of 225 students completed Form A of the FEFT, 232 students completed Form B of the FEFT, and 155 students completed Forms A and B of the FEFT. Results suggest that the perceptual disembedding manifestations of field independence involve several dimensions, although these dimensions may be subsumed by a common higher-order factor. Results also support the conclusion that the research edition of the FEFT has reasonable psychometric integrity. Eight tables provide percentile equivalent scores, factor structure matrices, and item characteristic maps of the study data; and a 48-item list of references is included. (Author/SLD)
