Computerized dynamic visual tests for workplace applications: Effects of age and subsidiary issues

Workplace tasks require the processing of visual information and some are so dependent on vision that tests for task dependent visual capabilities are often used to screen job applicants. While visual acuity is still currently seen as the most important ability for the processing of visual information, other capabilities have also been recognized as important. A complete assessment of visual processing now entails, in addition to visual acuity, measures of contrast sensitivity, visual fields, scotopic and photopic sensitivity, depth perception, color vision, and eye muscle balance. Generally, these measures involve the use of stationary stimuli presented for a period of time and under static conditions. However, visual information processing in many workplace tasks involves the rapid presentation of visual images which change over time. (c) 2005 Elsevier B.V. All rights reserved.
