title: Comparison of interstimulus intervals on change detection in nondriving and driving scenarios.
abstract: Change detection across disruptions of visual scenes is typically studied using brief durations of the interstimulus interval (ISI) (i.e., up to 300 ms). We investigated change detection across durations that approximate longer, voluntary glances away from a visual scene (i.e., 500-2,000 ms), which are often actualized in driving situations. Experiment 1 found that in nondriving scenarios, change detection performance, as measured by accuracy and response time, decreased as ISI increased. Experiment 2 found that in driving scenarios, change detection for plausible changes also decreased as the ISI increased, but there was no similar decrease in performance for implausible changes. Both Experiments 1 and 2 showed that the necessary number of exposures to the change decreased as ISIs approximated voluntary glances, suggesting that change detection strategies may be modified at longer ISI durations.
