Although much research on reinforcement learning has focused on the striatum, the prefrontal cortex likely modulates this process. Given prior research demonstrating a consistent pattern of lateralized frontal cortical activity in affective responses and approach\/avoidance tendencies in the EEG literature, we aimed to elucidate the role of frontal EEG asymmetry in reinforcement learning. Thirty\u2010two participants completed a probabilistic selection task in which they learned to select some targets and avoid others though correct\/incorrect feedback. EEG indices of frontal cortical asymmetry were computed from alpha power recorded at baseline and during task completion. We also examined the feedback\u2010related negativity ERP component to assess feedback processing associated with activity in the dorsal anterior cingulate cortex. Results revealed that greater right\u2010lateralized frontal cortical activity during learning was associated with better avoidance learning, but neither left\u2010 nor right\u2010sided asymmetry reliably related to approach learning. Results also suggested that left frontal activity may relate to reinforcement feedback processing, as indicated by the feedback\u2010related negativity (FRN). These findings offer preliminary evidence regarding the role of frontal cortical activity in reinforcement learning while integrating classic and contemporary research on lateralized frontal cortical functions.<\/jats:p>","DOI":"10.1111\/psyp.12911","type":"journal-article","created":{"date-parts":[[2017,7,4]],"date-time":"2017-07-04T13:50:00Z","timestamp":1499176200000},"source":"Crossref","is-referenced-by-count":22,"title":["Frontal cortical effects on feedback processing and reinforcement learning: Relation of EEG asymmetry with the feedback\u2010related negativity and behavior"],"prefix":"10.1111","volume":"55","author":[{"given":"Petra C.","family":"Schmid","sequence":"first","affiliation":[{"name":"Swiss Federal Institute of Technology (ETH) Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leor M.","family":"Hackel","sequence":"additional","affiliation":[{"name":"Stanford University Palo Alto California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lee","family":"Jasperse","sequence":"additional","affiliation":[{"name":"New York University New York New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David M.","family":"Amodio","sequence":"additional","affiliation":[{"name":"New York University New York New York"},{"name":"University of Amsterdam Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,7,4]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ne.09.030186.002041"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsycho.2004.03.007"},{"key":"e_1_2_7_4_1","first-page":"164","volume-title":"Errors, conflicts, and the brain: Current opinions on performance monitoring","author":"Allen J.
