Question: Participants examined stimuli being displayed on a Samsung Syncmaster 2243, 48cm x 30cm with a resolution of 1680 x 1050 pixels and a 60 Hz refresh rate, from approximately a 50cm distance, which presented stimuli in black against a white backdrop. The Superlad forWindows 2.01 software (Cedrus Corporation) regulated the stimulus presentation timings where accuracy and reaction time were measured to the millisecond. This was accomplished by employing a mechanical serial mouse which was formerly stripped of the trackball. Need Assignment Help?
