Synchronizing stimulus displays with millisecond timer software for the IBM PC

Computer Technology


A C language technique for synchronizing millisecond timer software to the appearance of the stimulus on the IBM PC’s video monitor is described. Tachistoscopic programs that use the technique can correct the mean 8.3-msec bias normally found in reported response latencies and reduce the associated error variance.
