Spatial frequency masking with the sweep-VEP
A suprathreshold sinewave grating can change the amplitude of the steady-state visual evoked potential (VEP) in response to a test grating if the two are close in spatial frequency (SF). The change in amplitude provides clues to underlying pattern analyzers. Masking was measured in 12 observers using the steady-state VEP. As a test grating reversed at 7 Hz, a masker of similar temporal frequenc...
متن کاملSpatial frequency masking and Weber's Law.
The threshold masking effect of one simultaneously presented grating upon another was studied as a function of mask contrast and frequency. The masking function typically obeys Weber's Law with method-of-adjustment psychophysics, and typically does not with forced-choice. This apparent discrepancy was studied in some detail. We suggest that thresholds can be set with at least two different crit...
متن کاملSpatial frequency effects in masking by light.
Observers detected briefly pulsed sine-wave gratings presented with various asynchronies before, during or after a 700 msec conditioning flash. Although the conditioning flash raised increment thresholds for detection of both low and high spatial frequency gratings, shapes of the masking curves differed. Curves for low spatial frequency gratings exhibited peaks at the conditioning field on and ...
متن کاملPredicting masking release of lateralized speech
Lőcsei et al. (2015) [Speech in Noise Workshop, Copenhagen, 46] measured speech reception thresholds (SRTs) in anechoic conditions where the target speech and the maskers were lateralized using interaural time delays. The maskers were speech-shaped noise (SSN) and reversed babble with 2, 4, or 8 talkers. For a given interferer type, the number of maskers presented on the target’s side was varie...
متن کاملFaster, stronger, lateralized: low spatial frequency information supports face processing.
Distinct visual pathways are selectively tuned for processing specific spatial frequencies. Recently, Awasthi, Friedman, and Williams (2011) reported fast categorisation of faces at periphery, arguing for primacy of low spatial frequency (LSF) information in face processing. However, previous studies have also documented rapid categorization of places and natural scenes. Here, we tested if the ...
