The spatial tuning of "motion streak" mechanisms revealed by masking and adaptation

Apthorp, Deborah; Cass, John; Alais, David


We previously reported that fast-moving dot arrays cause orientation-tuned masking of static gratings (D. Apthorp, J. Cass, & D. Alais, 2010), which we attribute to "motion streaks." Using similar "streaky" dot motion, we describe spatial frequency tuning of grating threshold elevations caused by masking (Experiment 1) and adaptation (Experiment 2) to motion. To compare the streaks with psychophysical tunings, we Fourier analyzed time-averaged translating dots, which were bandpass (peaking at...[Show more]
