Presentation Transcript

  1. What can humans see with a single glance?

  2. Were there any animals in the picture? What was in the middle of the scene? Was this a natural or artificial environment?

  3. What object was here? How many chairs were there? Was this an indoor or outdoor environment?

  4. Interesting questions • What can people perceive from a short glance? • with masking? • without masking but also without eye movements? • How does perception improve with additional processing time? • What’s different when subjects know the questions beforehand? • performance always better? • are there tasks for which there’s no difference?

  5. Project components • Design behavioral experiment • stimuli, experimental conditions • questions posed to subjects • Perform pilot experiments on small number of subjects • Analyze results

  6. Resources • Yours truly (cheston@mit.edu) • Fei-fei, Iyer, Koch & Perona (JoV 2007) • http://jwww.journalofvision.org/content/7/1/10.full • Psychtoolbox (psychtoolbox.org)
