  • The detection of mirror symmetry has been investigated by measuring discriminability (d') between two populations of dot displays that contain mirror pairs and random dots in different proportions. The difficulty of the task was varied by changing the proportions of paired dots in the two populations, and also by changing the accuracy of positioning the paired dots. Symmetry can be detected in brief exposures, monocularly or binocularly. when the axis is not vertical, and when the axis is not… CONTINUE READING
