I’m trying to simultaneously play an mpg file on one side of the screen and a set of letters (as a picture file) at a rate of one per second on the other side of the screen. The pupose is to measure a subject’s ability to resist the distraction of the movie while attending to a letter task.
In experimenting, I’ve also noticed that I can’t get two sets of letters to display in different portions of the screen at the same time. If both are linked to the same block and trial, they display alternately.
My attempts to solve the problem have involved creating one block, one trial, and two events, one with the movie and the other taking letters from a stimulus list.
