ABSTRACT
After having chosen a suitable set of stimuli, any researcher who is interested in running perceptual experiments will need to worry about how to display or render the stimuli and how to record the answers of the participants. For the end user, the perfect stimulus-presentation software would allow for easy specification of various experimental designs and would interface with various hardware devices both on the input and output side. In addition, it would offer precise and accurate timing under all experimental conditions, as well as play back or render a number of different sensory stimuli-ranging from text in UNICODE format to images to movies in various formats, up to 3D-Audiopreferably while keeping audio and video synchronized. Finally, it should save the acquired data in an easy-to-parse format, and gracefully handle missing data values, as well as unexpected experimental situations.
