Sound alters visual motion perception

Sound alters tactile motion perception

Recently Sekuler et al. (Nature, 1997) investigated the motion-bounce illusion and found that sound can influence ambiguous visual motion perception. Here we investigated the motion-bounce illusion in the tactile-auditory domain. Using a vibro-tactile belt consisting of 7 vibrators we generated tactile apparent motion stimuli by sequentially activating neighboring motors with an onset of 200ms ...

Static sound timing alters sensitivity to low-level visual motion.

Visual motion processing is essential to survival in a dynamic world and is probably the best-studied facet of visual perception. It has been recently discovered that the timing of brief static sounds can bias visual motion perception, an effect attributed to "temporal ventriloquism" whereby the timing of the sounds "captures" the timing of the visual events. To determine whether this cross-mod...

Music Alters Visual Perception

BACKGROUND Visual perception is not a passive process: in order to efficiently process visual input, the brain actively uses previous knowledge (e.g., memory) and expectations about what the world should look like. However, perception is not only influenced by previous knowledge. Especially the perception of emotional stimuli is influenced by the emotional state of the observer. In other words,...

Sound can suppress visual perception

In a single modality, the percept of an input (e.g., voices of neighbors) is often suppressed by another (e.g., the sound of a car horn nearby) due to close interactions of neural responses to these inputs. Recent studies have also suggested that close interactions of neural responses could occur even across sensory modalities, especially for audio-visual interactions. However, direct behaviora...
