There exist conditions where an observer experiences fluctuations in perception despite un-  
  changing visual stimulation, with a given perceptual interpretation moving in and out of aw-  
  areness. The presented stimulus switches between two competing states of awareness, imp-  
  lying Bistable perception can also be induced by presenting dissimilar monocular patterns to  
  corresponding areas of the two eyes. Called binocular rivalry, these stimulus conditions pro-  

duce patent fluctuations in visual awareness.

  We have experimental set-up for studying bistable perception during binocular rivalry.

We have been studying bistable perception and its interaction with other perceptual and

  cognitive processes with both psychophysical and neuroscientific methods.

Exciting new studies on bistable perception are on-going. Topics include,

  • Bistable perception influenced by fear conditioning
  • Investigation into the neural “cause” for conscious visual awareness during binocular rivalry examined by subdural electrical stimulation methods
  • Binocular rivalry modulated by social associative learning

Our research on bistable perception has been supported by NRF research grants including,

  • “Does modulation of brain activities cause the change of conscious state?
