*Question for psychtoolbox users*
I using one screen. The function "flip" flips all screen. Can i divided the screen to two areas of "flip"? I have two stimuli with different time display flipping one of them flips both of them. Any suggestions how to solve this?
I suggest you follow: http://courses.washington.edu/matlab1/Lesson_1.html

Yael:
If I understand your question correctly, the solution is to make sure to draw the stimulus that is to remain longer on the display you are replacing the first display with.
So, if you have an 'A' on the left that is to remain for 100 ms and a 'B' on the right that is to remain for 200 ms you would first draw a screen with A and B, flip that, then draw a screen with only B, and flip that 100 ms after the first flip, and then draw a screen with nothing and flip that 100 ms after the second flip. That would show A for 100 ms and B for 200 ms (100 ms with A on the screen and then 100 ms by itself).
Respectfully,
Greg
