Tachistoscopic applications of Micro Experimental Laboratory (MEL) used with IBM PC compatibles: Stimulus and response timing issues

IBM PCs and compatibles are increasingly used in psychological research for tachistoscopic tasks, which require precise control of timing of stimulus durations and accurate measurement of response latencies. The application of MEL in such research is discussed; several precautions which influence stimulus timing are noted, and some data on measurement error with keypress responses are presented.
