Variation in vernier acuity with age
Many visual functions deteriorate with increasing age, vernier acuity apparently being an exception. We used an improved experimental protocol to investigate vernier thresholds in subjects in four age groups. Vernier threshold was found to increase with increasing age, and the difference in this, compared with previous findings is probably due to the smaller inter-pixel angle used. Vernier acui...
متن کاملComments on: variation in vernier acuity with age
Comments on: variation in vernier acuity with age Li, Edwards, and Brown (2000) recently reported variation in vernier acuity with age in Vision Research. We have addressed this issue using somewhat different test displays, test conditions, and paradigms. The paper by Li et al., kindly cites a number of papers presented by our research group; here we add only related non-There seems to be a sub...
متن کاملSpatio-temporal vernier acuity.
The study of space-time vernier (STV) provides information on the spatio-temporal structure of the visual system in the same way that the classical spatio-spatial vernier (SSV) provides information on its spatial structure. The transposition of a SSV task into a STV one yields the following experimental format: an object (in the present case a Gaussian Blob) drifts with a constant velocity, V, ...
متن کاملVernier acuity with plaid masks: the role of oriented filters in vernier acuity
Superimposition of oriented grating masks on vernier targets results in bimodal patterns of vernier threshold elevation, with peaks occurring on either side of vernier target orientation. These bimodal masking effects suggest a contribution to vernier acuity from spatial filters tuned to orientations on either side of the target. We report similar bimodal threshold elevation with plaid masks co...
متن کاملAnisotropies in peripheral vernier acuity.
Vernier acuity for short horizontal, vertical and oblique target lines was measured in many locations in the periphery of the visual field in normal human observers. In the 10 deg periphery, the average alignment threshold with oblique vernier lines in eight locations for three observers was 2.29 times higher than that with vertical and horizontal target lines. This oblique effect was found eve...
