Backward Masking for Letters

Perceptual and Motor Skills, 1965
This study investigated extent of backward masking for letters under conditions where test stimulus and masking stimulus were the same or different. Two response measures were used, detection of location and identification of the test stimulus. The extent of masking, as assessed by detecting location, was greater when test and masking stimuli were ...

Developmental Differences in Visual Backward Masking

Child Development, 1980
2 experiments were conducted to examine developmental differences in visual recognition masking when verbal encoding and response demands are minimized. Precautions were taken in the experiments to ensure the implication of the central visual system in the backward-masking component of each experiment.

Reaction Time Measures of Backward Masking

The Journal of General Psychology, 1988
We employed both simple and choice reaction time (RT) paradigms in which the subjects were required to respond to 3.0 cycles per degree (c/d) square-wave gratings presented to one eye, while checkerboard masks were presented at various stimulus-onset asynchronies to the other eye. No masking was evident using the simple RT paradigm, but with the choice

Age differences in backward dichoptic masking

Experimental Aging Research, 1975
An investigation of age differences in backward dichoptic visual noise masking was carried out with young, middle-aged and old subjects. Older subjects were found to be significantly more susceptible to the backward masking effect over longer delays between the target and masking stimuli.

Temporal Summation During Backward Visual Masking*

Journal of the Optical Society of America, 1969
In this paper, I plan to talk about the latest in a series of experiments on visual masking which were done over the past several years at Rochester. Peter Schiller’s very lucid presentation (P. H. Schiller, this volume) provides an excellent background for this, and gives one something to think about in the electrophysiological domain, which might be ...

Visual Backward Masking of Selected Visemes

Journal of Speech, Language, and Hearing Research, 1982
Five adult subjects with normal hearing and vision viewed tachistoscopically projected photographs of a talker uttering six phonemes. Experiment 1 determined discrimination of the visemes as a function of exposure duration (12–14 msec) and demonstrated that recognition of certain lip postures was a direct function of duration whereas for other postures

Backward masking by pattern stimulus onset.

Journal of Experimental Psychology: Human Perception and Performance, 1981
The backward masking effects of the offset of a pattern stimulus on the apparent contrast of a target stimulus were determined to be a function of target onset-mask offset asynchrony. With spatially overlapping stimuli and binocular viewing, a monotonic function similar to that characterizing early dark adaptation was obtained; with a dichoptically ...

Backward and Forward Masking

International Journal of Audiology, 1971
Experiments on auditory backward and forward masking show elevated thresholds for a signal which occurs soon before (backward masking) or soon after (forward masking) another sound of sufficient intensity (masker). More backward than forward masking occurs for very short, silent, time intervals (t).

Are Masking Abnormalities in Schizophrenia Limited to Backward Masking?

International Journal of Neuroscience, 2009
Schizophrenia, it has been proposed, is associated with deficits in the magnocellular part of the visual system. In support of this suggestion, it has been claimed that schizophrenic subjects have abnormal backward masking. However, if this abnormality is to be linked specifically to magnocellular defects, then it must be specific to backward masking ...

A model of visual backward masking

Biosystems, 2005
When two successive stimuli are presented within 0-200 ms intervals, the recognition of the first stimulus (the target) can be impaired by the second (the mask). This backward masking phenomenon has a form called metacontrast masking where the target and the mask are in close spatial proximity but not overlapping.
