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. |
