What is the masking effect?

What is the masking effect?

A large-amplitude stimulus often makes us less sensitive to smaller stimuli of a similar nature. This is called a masking effect. In a sound, a small-amplitude quantization error may not be heard if it is added to a strong signal component in the same frequency neighborhood.

What is a masking stimulus?

Masking refers to the difficulty in seeing one stimulus, the target stimulus, when it is quickly replaced by a second stimulus that occupies the same or adjacent spatial locations.

What is masking in memory?

Abstract. The presentation of a similar but irrelevant stimulus immediately following presentation of a memory item is called masking. Masking is known to reduce performance on working memory tests. This is the type of memory used to hold information in mind for brief periods of time for use in ongoing cognition.

What is masking in reading?

Masking card: Available in Online Resources in various sizes, masking cards bring sharp attention to words within continuous text. The mask places a frame around a word so that children can isolate and concentrate on it.

What is the role of visual masking in cognitive science?

Masking is an important part of the study of perception and cognition. It is used both to investigate the properties of the visual system and as a tool to isolate many other aspects of cognition.

What happens in the procedure known as binocular rivalry?

Binocular rivalry is a visual phenomenon that occurs when dissimilar monocular stimuli are presented to corresponding retinal locations of the two eyes. Binocular rivalry is a compelling example of multistable perception wherein physically invariant stimulation leads to fluctuations in perception.

What is backward visual masking used for in consciousness science?

Backward masking renders a visual stimulus invisible by presenting a second stimulus shortly (e.g., 40 ms) after the first. Applying TMS to early visual areas at a latency far beyond the FFS still renders stimuli invisible.
