{"pk":27044,"title":"Insomniacs Misidentify Angry Faces as Fearful Faces Because of Missing the Eyes:\nAn Eye-Tracking Study","subtitle":null,"abstract":"Insomniacs were found to have compromised perception of\nfacial expressions. Through eye movement examinations,\nhere we test the hypothesis that this effect is due to impaired\nvisual attention functions for retrieving diagnostic features in\nfacial expression judgments. 23 individuals with insomnia\nsymptoms and 23 non-insomniac controls completed a task to\ncategorize happy, sad, fearful, and angry faces. The\ninsomniacs were less accurate to recognize angry faces and\nmade more “fearful” mistakes than controls. A hidden\nMarkov modeling approach for eye movement data analysis\nrevealed that when recognizing angry faces, more insomniacs\nadopted an eye movement pattern focusing on the mouth\nwhile more controls adopted a pattern attending to both the\neyes and the mouth. This result is consistent with previous\nfindings that the primary diagnostic feature for recognizing\nangry faces is the eyes suggesting that impaired information\nselection through visual attention control may account for the\ncompromised emotion perception in insomniac individuals.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"insomnia; eye-tracking; hidden Markov model;\nfacial expression"}],"section":"Talks: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/45p994fk","frozenauthors":[{"first_name":"Jinxiao","middle_name":"","last_name":"Zhang","name_suffix":"","institution":"The University of Hong Kong","department":""},{"first_name":"Antoni","middle_name":"B.","last_name":"Chan","name_suffix":"","institution":"The City University of Hong Kong","department":""},{"first_name":"Esther","middle_name":"Y.Y.","last_name":"Lau","name_suffix":"","institution":"The Education University of Hong Kong","department":""},{"first_name":"Janet","middle_name":"H.","last_name":"Hsiao","name_suffix":"","institution":"The University of Hong Kong","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/27044/galley/16680/download/"}]}
