{"pk":29823,"title":"Motor Chunking During Sequence Learning in Grid-Navigation Tasks","subtitle":null,"abstract":"Several canonical experimental paradigms (serial reaction task, mxn task, etc.) have been proposed to study the typi-cal behavioural phenomena in a sequential motor key-press task. The repeated execution of visuomotor sequences insuch paradigms lead to overall performance improvement such that the inter-response intervals in between certain sub-sequences decreases as compared to that across other sub-sequences. This efficient and hierarchical cluster organisation iscalled motor chunking. We provide empirical evidence for motor chunking in grid-navigation sequencing tasks. The par-ticipants performed Grid-Sailing Task (GST) [Fermin et. al., 2010] that required navigating a 10x10 grid from start to goalposition while using a particular key-mapping between the 3 cursor movement directions and the 3 keyboard buttons. Thisstudy confirms the emergence of subject-specific, unique temporal patterns related to chunking after substantial practice.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Poster Session 2","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5zn5g4r7","frozenauthors":[{"first_name":"Krishn","middle_name":"","last_name":"Bera","name_suffix":"","institution":"IIIT-Hyderabad","department":""},{"first_name":"Anuj","middle_name":"","last_name":"Shukla","name_suffix":"","institution":"IIIT-Hyderabad","department":""},{"first_name":"Raju","middle_name":"","last_name":"Bapi","name_suffix":"","institution":"IIIT-Hyderabad","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/29823/galley/19677/download/"}]}
