Raw Data: Factors limiting sensitivity to binocular disparity in human vision

Data from 53 subjects in three experiments. Experiment 1 (53 subjects): Four-alternative forced choice task where subjects viewed a field of black and white dots. They located which location (of four) contained a wedge-shaped target in either crossed or uncrossed disparity. Stimuli were presented for an unlimited duration. Experiment 2 (18 subjects): As above but with stimulus duration reduced to 250 ms. Also, stimuli now contained disparity noise (standard deviation of 0 to 512 arc seconds) applied to each dot. This allowed us to measure noise-masking functions. Experiment 3 (11 subjects): Control experiment with duration further reduced to 50 ms.
