Hands help hearing: Facilitatory audiotactile interaction at low sound-intensity levels

Hands help hearing: facilitatory audiotactile interaction at low sound-intensity levels.

Auditory and vibrotactile stimuli share similar temporal patterns. A psychophysical experiment was performed to test whether this similarity would lead into an intermodal bias in perception of sound intensity. Nine normal-hearing subjects performed a loudness-matching task of faint tones, adjusting the probe tone to sound equally loud as a reference tone. The task was performed both when the su...

Magnetoencephalographic correlates of audiotactile interaction.

To seek for correlates of an interaction between auditory and somatosensory processing, the brain's magnetic field in response to simultaneously presented auditory (A) and tactile (T) stimuli was compared with the sum of the respective unimodal responses (A+T). The stimuli were binaural 1047-Hz tone bursts of 60 dB sensation level and tactile pressure pulses to the right thumb. The mean interva...

The facilitatory role of sound symbolism in infant word learning

Sound symbolism or the nonarbitrary link between language sound and meaning are commonly found across many languages of the world. A well-known example is the association between rounded vs. angular shapes and labels (i.e., the Bouba-kiki effect by Köhler, 1929/1947). Previous research has shown that sound symbolic words play facilitative role for preschool children’s novel verb learning (Imai,...

Audiotactile interaction can change over time in cochlear implant users

Recent results suggest that audiotactile interactions are disturbed in cochlear implant (CI) users. However, further exploration regarding the factors responsible for such abnormal sensory processing is still required. Considering the temporal nature of a previously used multisensory task, it remains unclear whether any aberrant results were caused by the specificity of the interaction studied ...
