Perceptual Learning in Visual Backward Pattern Masking
Perceptual and Motor Skills, 2003The present study examined the practice effect of backward pattern masking in the context of recent researches on perceptual learning. On the discrimination task, thresholds decreased substantially with practice. In addition, the practice effect was specific to the mask pattern. In contrast, it cannot reasonably be assumed that the practice effect was

Perceptual masking of drug stimuli
Drug Development Research, 1989AbstractThree separate drug‐discrimination experiments, using pigeon subjects, were designed to assess the modification of a morphine (MS) stimulus by d‐amphetamine (AMPH). Experiment 1 examined the drug mixture in a two‐choice discriminative procedure in three groups of subjects trained to one of three doses of MS (1.0, 3.2, or 10 mg/kg) vs.

Perceptual and conceptual masking of pictures.
Journal of Experimental Psychology: Learning, Memory, and Cognition, 1984We report an experiment in which target pictures, presented for 50 ms, were followed by masks. Two mask variables were implemented: mask luminance and amount of attention demanded by the mask. Luminance but not attention demand affected subsequent picture-memory performance when the mask followed the picture immediately; however, attention demand but ...

Perceptual training affects linguistic release from masking
The Journal of the Acoustical Society of America, 2022Understanding speech in noisy conditions is a problem faced by all listeners. Previous studies have shown that listeners understand target speech better when background speech (masker) is in a different language. This is called Linguistic Release from Masking (LRM).

Gratings That Induce Perceptual Distortions Mask Superimposed Targets
Perception, 1996Masking is known to depend upon the relationship between the spatial-frequency content of target and mask. This relationship has been held constant in three experiments in order to investigate the separate contribution of the spatial parameters of the mask, in this case a grating with square-wave luminance profile.

No Masking between Test and Mask Components in Perceptually Different Depth Planes
Perception, 20112-D cues to perceived depth organization have been used to segregate test and mask stimulus components in a discrimination task. Observers made either spatial-frequency or orientation judgments on a rectangular test component by itself or in the presence of constant rectangular masks.

A perceptual metric for masking
IEEE International Conference on Acoustics Speech and Signal Processing, 1993Analytical tools were developed to predict masking of formant frequencies of steady-state vowels in the presence of a noise masker. Two kinds of masking were studied: within-band masking (where the signal frequency was within the bandwidth of a noise masker) and above-band masking (where the signal frequency was above the upper cutoff frequency of the ...

“The mask who wasn’t there”: Visual masking effect with the perceptual absence of the mask.
Journal of Experimental Psychology: Learning, Memory, and Cognition, 2015Does a visual mask need to be perceptually present to disrupt processing? In the present research, we proposed to explore the link between perceptual and memory mechanisms by demonstrating that a typical sensory phenomenon (visual masking) can be replicated at a memory level.

Masking Effects Induced by Perceptual Colour Components
Perception, 1997Signals from the three types of cone photoreceptors are generally thought to be combined into two opponent-colour components and an achromatic component. Here we have chosen the cardinal directions Ach (achromatic axis), Cr1 (reddish - greenish axis) and Cr2 (bluish - yellowish axis) defined by Krauskopf to build a colour image coding scheme based on ...

Perceptual discrimination in monkeys: Retroactive visual masking
Physiology & Behavior, 1969Abstract Five monkeys were trained to discriminate between a square and a triangle presented in a 5 msec tachistoscopic flash with 95–100 per cent accuracy. An essential feature of this trained performance was a programmed sequence of events in which the monkey learned to attend following self-triggering of the stimulus flash.
