{"pk":26517,"title":"Stop paying attention: the need for explicit stopping in inhibitory control","subtitle":null,"abstract":"Inhibitory control, the ability to stop inappropriate actions, isan important cognitive function often investigated via the stop-signal task, in which an infrequent stop signal instructs the sub-ject to stop a default go response. Previously, we proposed arational decision-making model for stopping, suggesting theobserver makes a repeated Go versus Wait choice at each in-stant, so that a Stop response is realized by repeatedly choosingto Wait. We propose an alternative model here that incorpo-rates a third choice, Stop. Critically, unlike the Wait action,choosing the Stop action not only blocks a Go response at thecurrent moment but also for the remainder of the trial – thedisadvantage of losing this flexibility is balanced by the bene-fit of not having to pay attention anymore. We show that thisnew model both reproduces known behavioral effects and hasinternal dynamics resembling presumed Go neural activationsin the brain.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Bayesian model"},{"word":"decision-making"},{"word":"stochastic con-trol theory"},{"word":"Inhibitory control"},{"word":"stop-signal task"},{"word":"neural data"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5p0205c3","frozenauthors":[{"first_name":"Ning","middle_name":"","last_name":"Ma","name_suffix":"","institution":"University of California San Diego","department":""},{"first_name":"Angela","middle_name":"J.","last_name":"Yu","name_suffix":"","institution":"University of California San Diego","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26517/galley/16153/download/"}]}
