{"pk":27348,"title":"Experimental and Computational Investigation of the Effect of Caffeine onHuman Time Perception","subtitle":null,"abstract":"Perception of time is an active process that takes place contin-ually. However, we are yet to learn its exact mechanisms con-clusively. The temporal bisection task is ideal to investigate thecircuitry underlying time perception. Caffeine, a commonlyused stimulant, has been known to play a role in modulation oftime perception. The objective of this article is to explore therole of caffeine, a neuromodulator, in the perception of time inhuman beings by conducting suitable experiments. The exper-iment shows that an expansion of time is perceived by subjectsafter caffeine ingestion and that caffeine has an acceleratingeffect on our time perception system. Additionally, we presenta preliminary 2-step decision model that fits the results of theexperiment and potentially gives insights into the mechanismsof caffeine. We conclude by pointing out future directions to-wards a more biologically realistic computational model.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Caffeine; Timing; Perception; Temporal bisection;Computational modeling; Decision making"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6qr9x01f","frozenauthors":[{"first_name":"Remya","middle_name":"","last_name":"Sankar","name_suffix":"","institution":"International Institute of Information Technology","department":""},{"first_name":"Anuj","middle_name":"K.","last_name":"Shukla","name_suffix":"","institution":"International Institute of Information Technology","department":""},{"first_name":"Raju","middle_name":"S.","last_name":"Bapi","name_suffix":"","institution":"University of Hyderabad","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27348/galley/16984/download/"}]}
