This study explored the differences in visual search tasks for people with different cognitive styles of field independence and field dependence when browsing the different sequence of application layout on computer desktops. This experiment is a 2(Cognitive styles: field independence vs. field dependence) *2(Familiarity: familiar vs. unfamiliar) *2(Sequence of application layout: name vs type) design of mixed factors. The response time and fixation times of searching computer application were the dependent variables. The experiment method is : All participants took the test with the Group Embedded Figures Test(GEFT) , the top 25% and bottom 25% of the test scores are divided into styles of field-independent and field-dependent. They performed visual search tasks in different sequence of application layout on computer desktops with eye tracking devices. Each participant performed a total of 4 search tasks. It was found that there was a significant difference in the response time of the participants searching for familiar and unfamiliar applications. When the participants searched for familiar applications, their reaction time and number of fixations were significant differences. The difference between this research and previous research on people with different cognitive styles is that the previous research for field independent people can quickly find the target in an unfamiliar environment, but in this research, field independents did not find this feature in the search task for computer applications.
