However, it remains unclear whether such switch\u2010related positivities show similar scalp topography and index context\u2010updating mechanisms akin to those posed for domain\u2010general (i.e., classic P300) positivities in many task domains. To examine this question, ERPs were recorded from 31 young adults (18\u201330 years) while they were intermittently cued to switch or repeat their perceptual categorization of Gabor gratings varying in color and thickness (switch task), or else they performed two visually identical control tasks (go\/no\u2010go and oddball). Our task cueing paradigm examined two temporarily distinct stages of proactive rule updating and reactive rule execution. A simple information theory model helped us gauge cognitive demands under distinct temporal and task contexts in terms of low\u2010level S\u2010R pathways and higher\u2010order rule updating operations. Task demands modulated domain\u2010general (indexed by classic oddball P3) and switch positivities\u2014indexed by both a cue\u2010locked late positive complex and a sustained positivity ensuing task transitions. Topographic scalp analyses confirmed subtle yet significant split\u2010second changes in the configuration of neural sources for both domain\u2010general P3s and switch positivities as a function of both the temporal and task context. These findings partly meet predictions from information estimates, and are compatible with a family of P3\u2010like potentials indexing functionally distinct neural operations within a common frontoparietal \u201cmultiple demand\u201d system during the preparation and execution of simple task rules.<\/jats:p>","DOI":"10.1111\/psyp.12814","type":"journal-article","created":{"date-parts":[[2017,3,15]],"date-time":"2017-03-15T14:16:43Z","timestamp":1489587403000},"source":"Crossref","is-referenced-by-count":63,"title":["An information theory account of late frontoparietal ERP positivities in cognitive control"],"prefix":"10.1111","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6012-7116","authenticated-orcid":false,"given":"Francisco","family":"Barcel\u00f3","sequence":"first","affiliation":[{"name":"Laboratory of Neuropsychology University of the Balearic Islands Mallorca Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick S.","family":"Cooper","sequence":"additional","affiliation":[{"name":"Functional Neuroimaging Laboratory, School of Psychology University of Newcastle Callaghan Australia"},{"name":"Priority Research Centre for Brain and Mental Health University of Newcastle Callaghan Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,3,15]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"421","volume-title":"Attention and performance XV: Conscious and nonconscious information processing","author":"Allport A.","year":"1994"},{"key":"e_1_2_8_3_1","volume-title":"Applications of information theory to psychology: A summary of basic concepts, methods and results","author":"Attneave F.","year":"1959"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1162\/jocn.2006.18.10.1734"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhm111"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00001756-200210280-00011"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/neuro.09.013.2007"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1995.7.6.1129"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1897-04.2004"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2011.12.010"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/nn.3470"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2016.03.010"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0131556"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.3389\/neuro.10.001.2007"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2003.10.009"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.1981.tb01815.x"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2013.09.015"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10548-016-0512-4"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/ejn.12577"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0896-6273(01)00285-9"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brainres.2010.05.047"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.3758\/s13423-013-0499-8"},{"key":"e_1_2_8_23_1","first-page":"3","volume-title":"The Oxford handbook of event\u2010related potential components","author":"Kappenman E.
