{"pk":27043,"title":"Using mouse-tracking data to visualise decision landscapes","subtitle":null,"abstract":"Computerised paradigms have enabled decision making re-searchers to gather rich data on human behaviour, includinginformation on motor execution of a decision, e.g., by track-ing mouse cursor trajectories. As the number and complexityof mouse-tracking studies rapidly increase, more sophisticatedmethodology is needed to analyse the decision trajectories.Here we present a new computational approach to generat-ing decision landscape visualisations based on mouse-trackingdata. Decision landscape is an analogue of energy potentialfield mathematically derived from velocity of mouse move-ment during a decision. Visualised as a 3D surface, it pro-vides a comprehensive overview of motor evolution of deci-sions. Employing the dynamical systems theory framework,we develop a new method for generating decision landscapesbased on arbitrary number of trajectories. The decision land-scape visualisation have potential to become a novel tool foranalysing mouse trajectories during decision execution, whichcan provide new insights into the dynamics of decision mak-ing.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"decision making; mouse tracking; dynamical sys-tems; visualisation"}],"section":"Talks: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/88d034wq","frozenauthors":[{"first_name":"Arkady","middle_name":"","last_name":"Zgonnikov","name_suffix":"","institution":"National University of Ireland, Galway","department":""},{"first_name":"Andrea","middle_name":"","last_name":"Aleni","name_suffix":"","institution":"University of Naples Federico II","department":""},{"first_name":"Petri","middle_name":"","last_name":"Piiroinen","name_suffix":"","institution":"National University of Ireland, Galway","department":""},{"first_name":"Denis","middle_name":"","last_name":"O’Hora","name_suffix":"","institution":"National University of Ireland, Galway","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/27043/galley/16679/download/"}]}
