title: Psychology of computer use: XXX. Effects of presentation speed on pupil size using negative and positive CRTS.
abstract: The effects of presentation speed and both positive and negative CRT (cathode ray tube) displays on pupil size were studied. The pupillary areas of 12 female student volunteers were measured by infrared videopupillography. The three presentation speeds were no change for 12 sec., a change every 2 sec. for 12 sec., and a change every 1/2 sec. for 12 sec. Two-way analysis of variance showed that the pupil size in the negative displays was significantly larger than that in the positive displays. A difference in pupillary area results from different display speeds, irrespective of a difference in polarity.
