  • Title: Effects of motion on time perception.
    Author: Kroger-Costa A, Machado A, Santos JA.
    Journal: Behav Processes; 2013 May; 95():50-9. PubMed ID: 23454436.
    Abstract:
    To investigate the effect of motion on time perception, participants were asked to perform either a temporal discrimination task or a temporal generalization task while running or standing still on a treadmill. In the temporal discrimination (bisection) task, 10 participants were exposed to two anchor stimuli, a 300-ms Short tone and a 700-ms Long tone, and then classified intermediate durations in terms of their similarity to the anchors. In the temporal generalization task, 10 other participants were exposed to a standard duration (500ms) and then judged whether or not a series of comparison-durations, ranging from 300ms to 700ms, had the same duration as the standard. The results showed that in the temporal bisection task the participants produced more "Long" responses under the dual-task condition (temporal judgments+running) than under the single-task condition (temporal judgments only). In the temporal generalization task, accuracy in the temporal judgments was lower in the dual-task condition than the single-task condition. These results are discussed in the light of dual-task paradigm and of the Scalar Expectancy Theory (SET).
