Visual capture
Encyclopedia
In psychology
, visual capture is the dominance of vision
over other sense
modalities in creating a percept. The phrase (in French, captation visuelle) was coined by Frenchman J. Tastevin after he studied the tactile Aristotle illusion in 1937.
One example of visual capture is known as the "ventriloquism
effect," which refers to the perception of speech sounds as coming from a direction other than their true direction, due to the influence of visual stimuli from an apparent speaker. Thus, when the ventriloquism illusion occurs, the speaker's voice is visually captured at the location of the dummy's moving mouth (rather than the speaker's carefully unmoving mouth).
Another example of visual capture occurs when a sound
that would normally perceived as moving from left to right is heard while a person is viewing a visual stimulus that is moving from right to left; in this case, both sound and stimulus appear to be moving from right to left.
