In two experiments, the authors explored the minimum preview duration required by younger and older adults to demonstrate a preview benefit. Both experiments used the same range of five preview durations (371 to 586 ms) to discover the minimum critical preview duration required by younger (Experiment 1) and older (Experiment 2) adults. Experiment 1 revealed that a 414-ms preview was sufficient for younger adults to demonstrate a preview effect, which replicated earlier studies. In Experiment 2, we found that older adults required a 586-ms preview to demonstrate a preview effect. General slowing provided a good account of the data.
