In this program all possible "displays" are drawn beforehand. This way, you end up with a number of screens you can blit when needed. In other words: like a real tachistoscope.

Program info - programs start with schematic overview of 4 possible trials. - programs end with presentation of mean RT and PE. - 'z' and 'm' keys are used to respond. - to interrupt program, try 'ESC' instead of z or m.
