DO80 revisited (*) corresponding author 2021 Access copy available to the general public Unrestricted How do we choose words, and what affects the selection of a specific term? Naming tests such as the DO80 are frequently used to assess language function during brain mapping in awake surgery. The present study aimed to explore whether specific semantic errors become more probable under the stimulation of specific brain areas. Moreover, it meant to determine whether specific semantic characteristics of the items may evoke specific types of error. A corpus-based qualitative semantic analysis of the DO80 items, and the emitted naming errors to those items during direct cortical electrostimulation (DCE) revealed that the number of hyperonyms (i.e. 'vehicle' for car') of an item predicted the emission of a synonym ('automobile' for 'car'). This association occurred mainly in frontal tumor patients, which was corroborated by behavior to lesion analyses. In contrast, the emission of co-hyponyms was associated with tumors located in temporal areas. These two behaviorlesion associations thus dissociated, and were also dependent on item semantic characteristics. Cohyponym errors might generate from the disruption in a temporal semantic-to-lexical process, and the production of synonyms could be the result of an impairment in a frontal lexical-selection mechanism. A hypothesis on the lexical selection mechanisms exerted by the inferior frontal gyrus is proposed. Crucially, the present data suggest the need for more restrictive naming tasks, with items conditioned by tumor location. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.054 2021 PSYCHOLOGY, EXPERIMENTAL 33 / 91 = 0.363 2021 Q2 T2 BEHAVIORAL SCIENCES 30 / 53 = 0.566 2021 Q3 T2 NEUROSCIENCES 193 / 275 = 0.702 2021 Q3 T3 1.14 2021 Experimental and Cognitive Psychology 2021 Q1 Behavioral Neuroscience 2021 Q1 5.8 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Pellegrin, Serena De Bonaudo, Camila Semenza, Carlo Puppa, Alessandro della Salillas, Elena Universidad de Zaragoza (orcid)0000-0002-0873-5357 4009 730 Universidad de Zaragoza Dpto.
