Masker laterality and cueing in forward-masked intensity discrimination.
Forward-masked intensity discrimination was measured as a function of level in experiments designed to reveal insights into the mechanism(s) underlying the midlevel elevation of the Weber fraction. The standard and maskers were 1.0-kHz tones that were separated by 100 ms. Performance was measured for listeners with normal hearing using an adaptive procedure. In experiment 1, intensity discrimin...
متن کاملFrequency discrimination in forward and backward masking.
Frequency difference limens for pure tones preceded by a forward masker or followed by a backward masker were obtained across a wide range of signal levels. Relkin and Doucet [Hear. Res. 55, 215-222 (1991)] have shown that at a masker-signal delay of 100 ms, the thresholds of high-SR (spontaneous rate) auditory-nerve fibers are recovered, while the low-SR fiber thresholds are not. Therefore, fo...
متن کاملThe effects of spatial and temporal cueing on metacontrast masking
We studied the effects of selective attention on metacontrast masking with 3 different cueing experiments. Experiments 1 and 2 compared central symbolic and peripheral spatial cues. For symbolic cues, we observed small attentional costs, that is, reduced visibility when the target appeared at an unexpected location, and attentional costs as well as benefits for peripheral cues. All these effect...
متن کاملForward and Backward Masking with Brief Chromatic Stimuli
Visual masking typically occurs when mask and target are separated in time by less than 100 ms, and the form of this interaction might be expected to depend on the latency of the target and mask signals. We track psychophysically the time course of signals from the two colouropponent channels by using forward and backward masking, in which mask and target each stimulate only one colour channel....
متن کاملA comparison of forward versus backward recognition masking.
lias been effectively decreased by these 2 conditions, whether interference conditions were presented separately or in conjunction with each other. Therefore, it can be concluded from those experiments that preventing verbal rehearsal by counting backward and displacing items from the rehearsal buffer by an auditory probe constitute independent processes in the STM system, each contributing a g...
