Park S, et al. - Researchers ascertained if spatial suppression of motion was similarly decreased for older adults in parafoveal regions and if divided attention impacts on suppression strength because attention is known to impact on spatial interactions. Twenty younger adults (19–34 years), and 18 older adults (61–77 years) partook in the investigation. Older adults need significantly longer in peripheral vision to precisely identify stimulus motion than younger adults and show increased spatial suppression of motion. Once considered alongside previous evidence of reduced central fixation suppression, the study provides evidence of substantial differences between the mechanisms of foveal and parafoveal spatial suppression.
