Burmuineko aktibitate elektrikoa hizkuntz gaitasuna neurtzeko

Hizkuntza aztertzeko hainbat bide daude. Gaur egun, hizkuntzalariak gero eta elkarlan gehiago egiten ari dira biologo, genetista, neurologo eta psikologoekin batera, gizakiak eta beste animaliak bereizten dituen hizkuntz gaitasunaren oinarrien bila. Artikulu honetan, neurozientziaren teknikak hizkuntza aztertzeko nola erabil daitezkeen aztertzen da. Zehazki, hizkuntzaren prozesamendua burmuineko aktibitate elektrikoaren bidez nola azter daitekeen erakusten da, euskarazko hitz-hurrenkerak adibide gisa erabiliz

Negative Transfer Effects on L2 Word Order Processing

Does first language (L1) word order affect the processing of non-canonical but grammatical syntactic structures in second language (L2) comprehension? In the present study, we test whether L1-Spanish speakers of L2-Basque process subject-verb-object (SVO) and object-verb-subject (OVS) non-canonical word order sentences of Basque in the same way as Basque native speakers. Crucially, while OVS orders are non-canonical in both Spanish and Basque, SVO is non-canonical in Basque but is the canonical word order in Spanish. Our electrophysiological results showed that the characteristics of L1 affect the processing of the L2 even at highly proficient and early-acquired bilingual populations. Specifically, in the non-native group, we observed a left anterior negativity-like component when comparing S and O at sentence initial position and a P600 when comparing those elements at sentence final position. Those results are similar of those reported by Casado et al. (2005) for native speakers of Spanish indicating that L2-Basque speakers rely in their L1-Spanish when processing SVO-OVS word order sentences. Our results favored the competition model (MacWhinney, 1997).This research has been supported by grants from the Spanish Ministerio de Economia y Competitivad and Ministerio de Ciencia e Innovacion (FFI2015-64183-P and RYC-2010-06520) and the Basque Government (IT665-13)

Beñat Oihartzabali Gorazarre: Festschrift for Bernard Oyharçabal / Ricardo Etxepare, Ricardo Gómez, Joseba Andoni Lakarra (arg./eds)[EN] After a brief introduction to ERP methods in the study of language, we report some recent results from a set of experiments investigating morphosyntactic processing in Basque. First we report results from experiments that focus on word-order processing, with special attention to verb medial sentences, where subjects show no preference for either SVO or OVS orders, in contrast with the sharp asymmetry found in SOV versus OSV orders in previous work. Second, we report results from a set of conductual and ERP experiments targeted to explore object agreement, which suggest that it is neurocognitively distinct from subject agreement.Ikertzaileek BRAINGLOT, CSD2007-00012/CONSOLIDER-INGENIO 2010 (MICINN), SEJ2007-60751/PSIC (MEC), eta GIU06/52 (Eusko Jaurlaritza-EHU) proiektuen babesa jaso dute

On The Nature Of Clitics And Their Sensitivity To Number Attraction Effects

Pronominal dependencies have been shown to be more resilient to attraction effects than subject-verb agreement. We use this phenomenon to investigate whether antecedent-clitic dependencies in Spanish are computed like agreement or like pronominal dependencies. In Experiment 1, an acceptability judgment self-paced reading task was used. Accuracy data yielded reliable attraction effects in both grammatical and ungrammatical sentences, only in singular (but not plural) clitics. Reading times did not show reliable attraction effects. In Experiment 2, we measured electrophysiological responses to violations, which elicited a biphasic frontal negativity-P600 pattern. Number attraction modulated the frontal negativity but not the amplitude of the P600 component. This differs from ERP findings on subject-verb agreement, since when the baseline matching condition obtained a biphasic pattern, attraction effects only modulated the P600, not the preceding negativity. We argue that these findings support cue-retrieval accounts of dependency resolution and further suggest that the sensitivity to attraction effects shown by clitics resembles more the computation of pronominal dependencies than that of agreement.This research has been supported by grants from the Spanish Ministerio de Economia y Competitividad and Ministerio de Ciencia e Innovacion (FFI2014-55733-P; FFI2015-64183-P; RYC-2010-06520, RYC-2013-14722), and the Basque Government (IT665-13)
