{"pk":28105,"title":"Behavioral Oscillations in Verification of Relational Role Bindings","subtitle":null,"abstract":"Human understanding of relations between objects depends onthe ability to code meaningful role bindings. Computationalmodels of relational reasoning have proposed that neuraloscillations provide a basic mechanism enabling workingmemory to code the bindings of objects into relational roles.We adapted a behavioral oscillation paradigm to investigatemoment-to-moment changes in representations of semanticroles. On each trial, a picture was presented showing an action(chasing) relating two animals, one animal playing an agentrole (chaser) and the other playing a patient role (chased). Afterthe picture disappeared, the inter-stimulus interval (ISI) wasvaried in densely-sampled increments followed by a verbalprobe indicating an animal in a role. Reaction time (RT) todecide the validity of the verbal probe was recorded. We foundthat RTs varied systematically with ISI in an oscillatoryfashion. A task that required memory for a relational roleevoked stronger theta- and alpha-band oscillations than did amemory task not involving relational roles. The behavioraloscillation patterns in the role-identification task revealed aphase shift between the two semantic roles in the alpha band.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"behavioral oscillation; neural oscillation;propositional representation; relations; binding."}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/85n418nt","frozenauthors":[{"first_name":"Yujia","middle_name":"","last_name":"Peng","name_suffix":"","institution":"UCLA","department":""},{"first_name":"Pratyusha","middle_name":"R","last_name":"Javangula","name_suffix":"","institution":"UCLA","department":""},{"first_name":"Hongjing","middle_name":"","last_name":"Lu","name_suffix":"","institution":"UCLA","department":""},{"first_name":"Keith","middle_name":"J","last_name":"Holyoak","name_suffix":"","institution":"UCLA","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28105/galley/17757/download/"}]}
