{"pk":25407,"title":"A dynamic neural field model of self-regulated eye movements during category learning","subtitle":null,"abstract":"Computational models of category learning and attention have\nhistorically focused on capturing trial and experiment level\ninteractions between attention and decision. However,\nevidence has been accumulating that suggests that the\nmoment-to-moment attentional dynamics of an individual\naffects both their immediate decision-making processes as\nwell as their overall learning performance. To extend the\nscope of these formal theories requires a modeling approach\nthat can index fine-grained decision-making at millisecond\ntime scales. Here we implement a model of eye movements\nduring category learning using concepts from Dynamic\nNeural Field Theory research. Our model uses a combination\nof timing signals, spatial competition and Hebbian association\nto simultaneously account for a number of foundational\nattentional efficiency results from eye tracking and category\nlearning. We report the results of fitting this model to\naccuracy, fixation probabilities, fixation counts and fixation\nduration data in 42 subjects from a standard category learning\nexperiment.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"attention"},{"word":"eye-tracking"},{"word":"dynamic field theory"},{"word":"cognitive modeling"},{"word":"category learning"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1t77n0fz","frozenauthors":[{"first_name":"Jordan","middle_name":"I","last_name":"Barnes","name_suffix":"","institution":"Department of Psychology, Simon Fraser University","department":""},{"first_name":"Mark","middle_name":"R","last_name":"Blair","name_suffix":"","institution":"Department of Psychology, Simon Fraser University","department":""},{"first_name":"Paul","middle_name":"F","last_name":"Tupper","name_suffix":"","institution":"Department of Mathematics, Simon Fraser University","department":""},{"first_name":"R","middle_name":"Calen","last_name":"Walshe","name_suffix":"","institution":"Department of Psychology, The University of Edinburgh","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2015-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/25407/galley/15031/download/"}]}
