TY - JOUR PY - 2001// TI - Visual search for traffic signs: the effects of clutter, luminance, and aging JO - Human factors A1 - Ho, Geoffrey A1 - Scialfa, Charles T. A1 - Caird, Jeff K. A1 - Graw, Trevor SP - 194 EP - 207 VL - 43 IS - 2 N2 - Latency and eye movement measures were used to examine the effects of aging, clutter, and luminance on visual search for traffic signs embedded in digitized images of driving scenes. Initially 14 older and 14 younger observers classified daytime and nighttime traffic scenes as containing low or high amounts of clutter. Next, an independent sample of 14 younger and 14 older participants searched for traffic signs contained within these scenes. Errors were more common among the elderly. Search efficiency declined with increased clutter and with aging. However, relative to the young, older adults did not suffer disproportionately as a result of increased clutter. The methods developed might be profitably employed to assess sign conspicuity and sign acquisition during driving.
