Freezing in Touch: Sound Enhances Tactile Perception

Freezing effect in tactile perception: sound facilitates tactile identification by enhancing intensity but not duration.

Identification of a visual target can be enhanced by a simultaneously presented high tone embedded in a sequence of low tones. This is called "freezing effect" because it is as if the target display was frozen in time by the tone. Until now, however, it has not been known whether this sound facilitation effect exists for a target with modalities other than vision, such as tactility, and if so, ...

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 ...

The Application of Tactile Experience in Urban Perception

Urban perception is the result of mutual transaction between human and environment and the process of perception is developed through the three continuous steps of “sensation”, “perception” and “cognition”. In the first step (sensorial perception), the environmental signals are received via sensorial sensors and each different sense based on its own essence, performance and ability has its own ...

Brain dynamics for perception of tactile allodynia (touch-induced pain) in postherpetic neuralgia.

Postherpetic neuralgia (PHN) is a debilitating chronic pain condition often accompanied by a sensation of pain when the affected region is touched (tactile allodynia). Here we identify brain regions involved in stimulus-induced touch-evoked pain (dynamical mechanical allodynia, DMA), compare brain activity between DMA and spontaneous pain (described earlier for the same patients in [Geha PY, Ba...
