Individual Differences in Pupil Size and Performance

  • W. Scott Peavler


Individual differences in pupil size are not surprising since they have been well documented by ocular scientists for years, although emphasis has typically been on abnormalities. What may be surprising, however, is the possibility that some of these presumably inherent differences may be related to performance characteristics of the individuals. I would like to discuss some research which suggests that certain pupillary measurements may be useful as performance predictors of individual capabilities, and/or group behavior. Before describing the first study (Peavler, in press), a brief review of some of the previous pupillary research seems appropriate.
