Description

We have developed a new method to measure visuospatial attention ability. This method measures the reaction time from the onset of a visual stimulus to a subject responding to it, in relation to representation space, kind of target and presence/absence of a cue. The purpose of this study was to confirm the reliability of the measurement method that we have developed. To confirm the reliability, we carried out the same test twice for the same subject, and calculated the coefficients of correlation between the two measurements. In the results, 0.739-0.980 significant coefficients of correlation were shown in 15 of 16 subjects. Significant coefficients of correlation were not shown in one subject. It was therefore concluded that the measurement method was almost reliable. However, because we did not obtain significant coefficients of correlation in one subject, we will consider improvements to our method to obtain more stable measurements in future.
