Interactions of backward and forward masking

The Journal of the Acoustical Society of America, 1977
The interaction between backward and forward masking was investigated for conditions in which a signal is presented in the same ear as the masker, monotically, or in the contralateral ear, dichotically. The SPL of a signal required for equal detectability was determined in both monotic and dichotic backward and forward masking paradigms and in ...

MLDs in Forward and Backward Masking

The Journal of the Acoustical Society of America, 1972
Masking-level differences (MLDs) of substantial magnitudes were found in forward and backward masking situations. Their magnitude diminishes exponentially as the silent interval between signal and masker increases. Implications of the data for current models relating to the MLD are suggested.

EFFECT OF PRACTICE ON VISUAL BACKWARD MASKING

Perceptual and Motor Skills, 1980
Five experiments studied practice effects for 4, 7, 11 subjects on visual backward masking using a signal-detection procedure under various conditions. Exp. I determined the minimum perceptible critical stimulus duration (CSD) for criterion identification of a target stimulus, the letter T or A. In Exp.

Perceptual Learning in Visual Backward Pattern Masking

Perceptual and Motor Skills, 2003
The 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

Forward and Backward Tactile Recognition Masking

The Journal of General Psychology, 1984
Forward and backward tactile recognition masking were investigated with a 15 by 15 array of tactile point-stimulators with the use of targets consisting of line segments differing in location and orientation and a random-dot embedding mask. Ss were paid graduate student volunteers (three males and one female). Durations of targets and masks were varied,

What's in a Mask? Information Masking with Forward and Backward Visual Masks

Quarterly Journal of Experimental Psychology, 2011
Three experiments tested how the physical format and information content of forward and backward masks affected the extent of visual pattern masking. This involved using different types of forward and backward masks with target discrimination measured by percentage correct in the first experiment (with a fixed target duration) and by an adaptive ...

Backward masking in bipolar affective disorder

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 1999
1. When an informational stimulus, the target, is followed closely in time by a non-informational stimulus, the mask, the visual system's processing of the informational stimulus is disturbed. This disturbance is known as backward visual masking. 2.

Potential Artifact in Dichoptic Backward Masking

Perceptual and Motor Skills, 1976
Under some conditions a dark interval in the target eye may be concomitant with presentation of a dichoptic mask. Results show that this monoptic dark interval contributes to the over-all observed dichoptic masking effect.

Dichotic Backward Masking of Complex Sounds

Quarterly Journal of Experimental Psychology, 1971
In the first experiment subjects identified a consonant-vowel syllable presented dichotically with a known contralateral masking sound at a stimulus onset asynchrony of ± 60 msec. When the mask followed the target syllable, perception of place of articulation of the consonant was impaired more when the mask was a different consonant-vowel syllable ...
