Document Summary
As of july 1, 2007, there were 4. 4 million adults over the age of 65 in canada (18. 7%) by 2031, 9. 13 million. Age related changes to sensory and information processing systems are important issues for instructors and designers: prime directive is to: How do these changes affect: retention and maintenance of previously acquired skills, the acquisition and retention of new skills (1) sensory loss. Visual decrements are common from about age 20. Changes to eye structure and retina begin to affect visual functioning at about 40 years. Poorer vision in low light: increased absolute difference threshold, increased sensitivity to glare, poor light adaptation. Changes in sensitivity to changes in illumination: loss of visual acuity, longer periods of visual accommodation. Inability to see detail and discriminate between patterns. Switching focus between objects at different distances: reduced colour discrimination. These changes are often interactive (e. g solving diff threshold problems increases glare problem) Age-related decline in hearing are commonplace and progressive.
