| Research Abstract |
The authors conducted experiments to see how the background color of Web-based tests (WBTs) can affect the brain activities of Web-based test takers. Subjects in their twenties took Web-based English grammar and listening tests and also performed circle-counting tasks on a computer screen with white, blue and light blue backgrounds. For all background colors, text and symbols were presented in black. Hemoglobin (Hb) concentration changes in the brain of each subject were recorded by using near-infrared spectroscopy (NIRS). On both the English tests and the counting tasks, the scores of the subjects were higher on average with the blue backgrounds than with the white background. The NIRS signals showed that linguistic areas in the brain tended to have higher oxy-Hb concentrations for the blue backgrounds than for the white background. These results suggest that a blue color may be a better choice for the background color of a WBT.
