To investigate the relationship between contrast detection and vernier acuity for abutting targets, the effects of varying target exposure duration (12-2000 msec) on vernier and contrast detection thresholds for long, thin lines and sinusoidal gratings (1 and 8 c/deg), were measured. Vernier thresholds decreased with both increasing exposure duration and increasing target contrast. Predictions made for equally visible targets show that the effect of exposure duration on vernier thresholds is… CONTINUE READING
