Abstract: | Older Ss, in the age range 30–55 years, were compared on certain temporal characteristics of visual perception. Experiment I confirmed a previous finding that older adults required an appreciably longer exposure duration to identify forms, even when equated with younger adults on standard measures of visual acuity. Experiment 2 found that older adults have a longer critical duration over which time-intensity reciprocity holds for form identification. The results were discussed in terms of such concepts of psychological time as the psychological moment. |
