title: Prospective duration judgments: the role of temporality and executive demands of concurrent tasks.
abstract: It is known that concurrent non-temporal tasks shorten reproduced temporal durations in prospective duration judgments. Two experiments were carried out, one comparing a concurrent temporal task to a minimally demanding concurrent task (Experiment 1) and one comparing an executive concurrent (Simon) task with a less demanding non-executive concurrent task (Experiment 2). An effect of the concurrent task type on temporal reproductions was found. Furthermore, a duration length effect was found, where longer durations were underestimated more than shorter durations. This effect tended to be stronger for the experiments that included a concurrent task that demanded high attention.
