Sentence examples for motion discrimination thresholds from inspiring English sources

We also predicted changes in motion discrimination thresholds as a function of the direction of motion in the surround.

This is in the range of themaximum repulsion effect (Pearson correlation coefficient computed between the absolute value of perceived upward motion and discrimination thresholds: r = 0.29, p < 0.001).

Our psychophysical results revealed a systematic change of the perceived motion direction and discrimination thresholds of a target stimulus due to the presence of a task irrelevant motion signal in the spatial surround.

Thus, it is also possible to predict the exact variation of the discrimination thresholds for the central target motion with different surround motion directions.

Evidently DF could still use information about transparent planes defined by motion and/or disparity to improve her depth discrimination thresholds – as well as or better than any of the control subjects we examined – despite being unable to perceive this information consciously.

Watson found that thresholds of motion detection and motion discrimination in healthy subjects are equal at sufficiently low spatial frequencies (e.g. 2 cpd) for both slow (1.5 Hz) and fast (12.4 Hz) movement of the test pattern [ 63].

Initially, discrimination thresholds were measured for two opposite directions of motion, followed by approximately 40 minutes of training on one of the directions.

Moreover, in the awake monkey the sensitivity to global motion of individual MT neurons, while increasing over time (for about 2 seconds), is comparable to the sensitivity of motion discrimination of both monkeys and humans, as assessed through coherence threshold [53].

Elevations of discrimination thresholds were strongest when the angle between center and surround motion was ±40 50° (similar to results of a previous study which used an adaptation paradigm, Hol and Treue 2001).

Speed discrimination thresholds were assessed by running three adaptive staircase procedures (QUEST) in parallel, one for each motion type.

Ball, K. & Sekuler, R. Direction-specific improvement in motion discrimination.
