This work aimed to study the relationship between individual differences in Behavioral Activation System (BAS) sensitivity and the neural underpinnings involved in processing a switching cue in a task-switching paradigm. BAS sensitivity was hypothesized to modulate brain activity in frontal regions, ACC and the striatum. Twenty-eight healthy participants un- derwent fMRI while performing a switching task, which elicited activity in fronto-striatal re- gions during the processing of the switch cue. BAS sensitivity was negatively associated with activity in the lateral prefrontal cortex, anterior cingulate cortex and the ventral striatum. Combined with previous results, our data indicate that BAS sensitivity modulates the neuro- cognitive processes involved in task switching in a complex manner depending on task de- mands. Therefore, individual differences in motivational dispositions may influence cognitive processing in the absence of reward contingencies info:eu-repo/grantAgreement/ES/MINECO/PSI2012-33054 info:eu-repo/grantAgreement/ES/MINECO/CSD2007-00012 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.057 2015 MULTIDISCIPLINARY SCIENCES 11 / 62 = 0.177 2015 Q1 T1 1.427 2015 Agricultural and Biological Sciences (miscellaneous) 2015 Q1 Medicine (miscellaneous) 2015 Q1 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ávila Rivera, César Rodríguez Pujadas, Aina Ventura Campos Noelia (orcid)0000-0002-8201-0469 Bustamante, Juan Carlos Universidad de Zaragoza Costumero Ramos, Víctor Rosell Negre, Patricia Barrós Loscertales Alfonso 4009 735 Universidad de Zaragoza Dpto.
