| Annotation | 10 younger adults (mean age 23.2) and 10 older adults (mean age 66.2) recruited from the University of Calgary and from the community in Calgary, Canada, were trained for 16 sessions on a two-dimensional search task with distractors. The target and one distractor were reversed after every fourth session. After the first four training sessions, on target-present trials, display size slopes were near zero for both age groups. However, on target-absent trails, older adults continued to show significantly larger display size effects than younger adults. There were no systematic differences to either the probability of fixating objects that possess the target's features or in the amount of disruption of any reversal. Thus, although older adults exhibited more conservative criteria in visual search, they developed prediction and flexible search skill to the same degree as their younger counterparts. These data have implications for models of visual attention, skill acquisition and cognitive ageing. (RH). |
