Abstract
This talk will describe some very common misconceptions that cognitive neuroscientists frequently express about the use of computers and related equipment for visual or auditory stimulus presentation, response collection and the timing precision and behaviour of computers and common operating systems in general. Some typical examples are assumptions about the suitability of LCD flat panels for timed and controlled visual stimulation, naive use of standard sound cards for timed auditory stimulation, and the use of keyboards and mice for reaction time measurements. The talk will try to point out solutions or remedies for some problems where available. The examples are based on an informal sampling of questions asked and misconceptions often encountered on the Psychtoolbox user forum.
