{"pk":29279,"title":"Using eye-tracking to examine the role of fluency in the number line placementtask","subtitle":null,"abstract":"The number line placement task, in which individuals are presented with a target number and mark where it would belocated along a number line, has played an important role in the investigation of numerical cognition. However, recentwork suggests that different factors may influence performance on the task, making it a poor proxy for mental represen-tation of number. In this study, adults completed a computer-based number line placement task with either standard ornon-standard endpoints. Consistent with previous research, responses in the standard condition were best fit by a linearmodel, while responses in the non-standard condition were best fit by a logarithmic model. In addition, eye-trackingdata revealed different looking patterns between conditions, including greater fixations on and more frequent alternationbetween endpoints in the non-standard condition and a leftward bias in the standard condition. This behavior may reflectdifferences in number familiarity and strategy use.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7gz9b8fg","frozenauthors":[{"first_name":"Samantha","middle_name":"","last_name":"Schwarz","name_suffix":"","institution":"Susquehanna University","department":""},{"first_name":"Jennifer","middle_name":"","last_name":"Asmuth","name_suffix":"","institution":"Susquehanna University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29279/galley/19150/download/"}]}
