SUMMARY:79. Investigating Stochastic Resonance in Tactile Discrimination
DESCRIPTION:Poster\n\nJayashri Prakash and Patricia R. DeLucia (Rice Unive
 rsity)\n\nStochastic resonance is a phenomenon where addition of noise to 
 a system enhances the system's signal-to-noise ratio. It can improve the a
 bility to detect weak signals. Lugo et al. (2008) showed that tactile dete
 ction threshold decreased when participants received auditory white noise.
  We aimed to replicate the results of Lugo et al. (2008), except that we m
 easured tactile discrimination. We examined whether discrimination between
  durations of vibrotactile stimuli would be better when auditory noise was
  presented. Participants performed a 2AFC task for three noise conditions:
  No noise, 45 dB, 55 dB. Seventeen out of twenty-four participants demonst
 rated increased tactile sensitivity when white noise was present compared 
 to when it was absent, which is not statistically significant. The optimal
  noise level varied among individuals. Eight participants performed best a
 t 45 dB and 4 at 55 dB. Hence, determining the ideal noise level for each 
 person is crucial for enhancing tactile sensitivity.\n\nTrack: Aerospace S
