{"pk":29995,"title":"Differences in Implicit vs. Explicit Grammar Processing as Revealed byHierarchical Weibull Modeling of Reaction Times","subtitle":null,"abstract":"Artificial language studies using reaction time-based measures have suggested grammar learning even in participants with-out awareness of underlying grammatical rules (Leung & Williams, 2011; Batterink, Reber, & Paller, 2014). However,traditional linear analyses of reaction times might not capture qualitative differences between participants with/withoutconscious rule awareness (Rouder, Lu, Speckman, Sun & Jiang, 2005; Rousselet & Wilcox, in press). In a partial repli-cation of one study (Batterink et al., 2014), participants were exposed to pseudoword articles that were predictive of anaccompanying English noun’s living/non-living status. Linear analyses showed that both rule-aware and rule-unaware par-ticipants exhibited slowdowns to rule-violating trials, indicating grammar learning. Hierarchical Weibull distribution anal-yses suggested that rule-unaware and rule-aware participants differed in the underlying cognitive mechanisms involved:rule-violating trials affected the processing architecture for both groups but only affected processing speed for rule-awareparticipants. These results illustrate the potential of yet-underused distribution-modeling approaches for second languagepsycholinguistics.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Poster Session 3","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5ft5c4wf","frozenauthors":[{"first_name":"David","middle_name":"","last_name":"Abugaber","name_suffix":"","institution":"University of Illinois at Chicago","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29995/galley/19849/download/"}]}
