The Present State of Pupillometrics

  • Eckhard H. Hess
  • Elizabeth Goodwin


As is well known, Hess and Polt (1960) published the first modern report on pupillometrics, which demonstrated, even though the methodology, in terms of controlling completely for brightness contrast, had not yet been perfected, that sequential pupil size changes in response to an experimental situation provide a quantified method of measuring or scoring how appealing or interesting something is. In the subsequent five years Hess gave many lectures and colloquia on his research over the country so that many scientific people learned about pupil phenomena even though the published literature was not yet extensive.
