title: Anisotropic resolution in children's vision.
abstract: Grating acuity was measured for 4 orientations in 111 children aged 3-8 yr. Results showed that 73% of the children had better acuity for horizontal and vertical compared to oblique gratings, 14% showed no anisotropy, and 13% had better acuity for oblique gratings. The magnitude of the oblique effect was 0.2 octaves, similar to that found in both younger children and adults.
