Perceptual Clarification

[Gopakumar Venugopalan]

The simplest way I can think off is by presenting the de-graded 
stimuli incrementally, frame by frame, and allowing a mouse click or 
serial response box button click for each one of the individual 
frames, which will cause it to move to the next trial, or it will 
automatically move at the end of the last frame to the next trial. I 
am working on something similar and this is something I have tried and 
worked. Paul De Groot did clarify and help with some ideas when I 
posed similar questions
