   The research questions we are currently pursuing is: How task-irrelevant information processing is suppressed by top-down attention? What is the time course of its working?
  To be more specific:

  1)  The research questions we are currently pursuing is: How task-irrelevant information processing is suppressed by top-down attention? What is the time course of its working?

  2)  Practical application of cognitive studies such as lie detection, human factor involved in accident proneness involving attention. For the latter purpose we use the Cognitive Failure Questionnare that measures attentional slip tendencies. We are exploring relationship between CFQ scores and various individual characteristics including the effect of mental fatigue on CFQ.

  3)  Emotion provoking stimuli, especially negative ones, are known to easily capture attention. We are now studying this automatic or preconscious nature of affective stimuli and its interaction with cognitive processes.
