{"pk":27409,"title":"Right hemisphere lateralization and holistic processing do not always go together:An ERP investigation of a training study","subtitle":null,"abstract":"Holistic processing (HP) and right-hemispheric lateralizationboth mark expertise in visual object recognition such as faceand sub-ordinate object perception. However, counter-examples have been found recently: Experiences of selectiveattention to parts such as writing experiences in Chinesecharacters reduced HP while increased right hemispherelateralization. We investigated the association between HPand brain activities measured by event-related potentials(ERP) in participants trained to recognize artificially-createdscripts using either whole-word or grapheme-to-phonemeapproaches. Stronger N170 activities were found in bothhemispheres in both training approaches. Though the type oftraining approaches induced opposite directions incorrelations between HP and the ERP signals in the righthemisphere: In the whole-word condition, the HP effectincreased with stronger right-hemispheric N170 activities;while the direction of this correlation was reversed in thegrapheme-to-phoneme condition. This demonstrates that HPand right hemispheric lateralization are separate processesthat are associated with different perceptual mechanisms.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"holistic processing"},{"word":"hemisphere lateralization"},{"word":"ERP"},{"word":"EEG"},{"word":"Perceptual expertise"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/91c8w669","frozenauthors":[{"first_name":"Ricky","middle_name":"Van-yip","last_name":"Tso","name_suffix":"","institution":"The Education University of Hong Kong","department":""},{"first_name":"Hangyu","middle_name":"","last_name":"Chen","name_suffix":"","institution":"The University of Hong Kong","department":""},{"first_name":"Yui","middle_name":"Andrew","last_name":"Yeung","name_suffix":"","institution":"The University of Hong Kong","department":""},{"first_name":"Terry","middle_name":"Kit-fong","last_name":"Au","name_suffix":"","institution":"The University of Hong Kong","department":""},{"first_name":"Janet","middle_name":"Hui-wen","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/27409/galley/17045/download/"}]}
