A series of experiments to discover extent of age differences in visual perception when temporal integration was required suggested that:
- 1Whore displays were simple, performance of different age groups was nearly equal, but with increasing complexity of displays older subjects were relatively increasingly slow in making correct identifications.
- 2With complex displays there was a relationship between degree of correct identification and (a) cumulative viewing time; (b) amount of display seen at one moment, such that an increase in both led to a greater improvement in performance of older subjects than an increase in either time or amount alone. Given a sufficient increase, performance of older subjects equalled that of younger.
- 3greater difficulty of older subjects with complex material appeared to be due mainly to greater amount of temporal integration required with such material.
