Title: The relationship of field-dependent/field-independent cognitive style to the perception and usage of digital color images

Abstract: This study investigated the relationship of field-dependent/field-independent (FD/FI) cognitive style to the perception of color images with respect to color-depth and preference for display layouts. In addition, the study investigated display characteristics that would affect performance on an image retrieval task in terms of time spent, recall memory, and screens changed/revisited. The GEFT was used to determine cognitive style, FD and FI. Ishihara's Test for Color-Blindness was used to detect any color vision deficiency. A randomized administration was employed to the subjects for the two experimental tasks: a color discrimination task and an image retrieval task. The treatment varied only in presentation order. Cognitive style was the primary independent variable for the two tasks. Presentation time was fixed as a control variable for the first task. Presentation order--blocked into two treatments: high density layout first or low density layout first--was employed as the second independent variable for the second task. The method of minimizing the influence of individual variation of FD/FI subjects was to compare the demographic factors and the treatments that may influence response. A correlational analysis was used to determine whether and to what degree, a relationship exists between two or more variables.

Results of the study did not support the hypotheses that cognitive style would be the primary predictor of performance on color discrimination task and image retrieval task. No consistent effect due to cognitive style was found. However, results indicated that FD subjects were more affected by different treatments than were FI subjects. This finding supported previous studies that FD is an important instructional variable. Results from this study showed that different treatments did make differences between FD/FI for the preference of display layouts. Implications for curriculum and system design are proposed. Furthermore, these results suggest that an ease of use design may be more useful than cognitive style consideration in enhancing search performance on an image retrieval task.
