Sound/Video Pairings (11-25-19)

Samermit and colleagues have determined that pairing disliked sounds (such as “nails scratching a chalkboard”) with videos presenting a more positive explanation for that sound (such as “someone playing a flute”) reduces the negative implications of hearing those sounds.  They report that “We propose that cross-sensory stimuli presenting a positive attributable source of an aversive sound can modulate negative reactions to the sound.”  The researchers utilized “original video sources (OVS) of eight aversive sounds (e.g., nails scratching a chalkboard) . . . .[and] positive attributable video sources (PAVS) of those same sounds (e.g., someone playing a flute)” as well as sound only recordings of the aversive sounds. The researchers determined that  “compared to the sounds alone . . . concurrent presentation of PAVS videos significantly reduced negative reactions to the sounds, and the concurrent presentation of OVS videos significantly increased negative reactions. . . . Our results provide novel evidence that negative reactions to aversive sounds can be modulated through cross-sensory temporal syncing with a positive attributable video source.”  Study participants rated the sounds, when they were presented with the videos and without the videos, on discomfort and unpleasantness, for example.
