Abstract

We have been developing a cognitive assessment system to detect subtle symptoms of mild cognitive impairment. Here, we examined the feasibility to evaluate the spatial cognition by the sequential delayed matching-to-sample task, in which the participants were required to select the figure with the same angle as the sample. We prepared four groups of the figures (Landolt ring, back of the right hand, chicken and map of Hokkaido) with a variation of 8 rotation angles (0°, ±45°, ±90°, ±135°, 180°). Data from 20 normal adult participants were recorded as a control group for the future of clinical trials. The reaction time tended to be extended according to the complexity of the figures. It also changed depending upon the figure’s rotation angle, though the effect was not necessarily linear from their upright position. These results suggest that our task might contribute to evaluate a higher spatial cognitive ability in daily life.
