Age-related differences in the processing of redundant visual dimensions.

Journal Article (Journal Article)

Age differences in the redundant-signals effect and coactivation of visual dimensions were investigated in 2 experiments. In Experiment 1 the task required the conjoining of dimensions, whereas in Experiment 2 the spatial separation of dimensions was manipulated. Although coactivation was evident for both age groups when the redundant dimensions occurred at the same location, older adults showed more evidence for coactivation, perhaps because of compensation for declines in perceptual processing. When the redundant dimensions were separated, neither age group showed evidence for coactivation. These findings indicate that the coactive processing of redundant visual dimensions is spared in healthy older adults and that for both groups, attention must be focused on both dimensions for coactivation to occur.
