Previous investigations of static and dynamic acuity have shown only inconsistent relations between measures of these aspects of visual performance. In the present study, six static and six dynamic visual sensitivity measures were gathered on 49 persons aged 7 to 61 years (M = 31 years). Contrary to previous findings, it was determined that when treated as latent factors with multiple indices, static and dynamic sensitivity are significantly correlated (r = 0.52). Further, both measures show an age-related decline, with dynamic sensitivity the most affected. Results have a bearing on models of spatial vision, efforts to determine screening procedures for performance in natural settings, and hypothesis concerning ontogenic decline in visual function.
