Publicación Real-Time Measures of the Multilingual Brain(Wiley, 2019-02-19) Wicha, Nicole; Carrasco Ortíz, Haydée; Moreno Bella, EvaThis chapter discusses how the electroencephalography (EEG) and magnetoencephalography (MEG) methods have been used to study the multilingual brain. It introduces the methods, the physiological basis of the data obtained from them, and the advantages and disadvantages of the methods compared to each other and to other neuroimaging techniques. The chapter briefly presents how these techniques have been used to address questions about the multilingual brain. The most common way of analysing continuously recorded language-related EEG and MEG data is to extract event-related potentials (ERPs) or event-related fields (ERFs), respectively. In a neurocognitive framework, the mastery of a second language is thought to involve the ability not only to represent linguistic knowledge, but also to process linguistic input in a native-like manner. The chapter briefly presents a sample of studies that have measured the brain signatures for language switching, first in production then during written sentence comprehension, in bilinguals and professional simultaneous interpreters.Publicación Code-switching and the brain(Cambridge University Press, 2009) Kutas, Marta; Wicha, Nicole; Moreno Bella, EvaPublicación Setbacks, pleasant surprises and the simply unexpected: brainwave responses in a language comprehension task(Oxford Academic) Rivera, Irene C.; Moreno Bella, EvaThis event-related potential (ERP) study explored the behaviour of N400 and post-N400 frontal positivities (pN400FP) during the processing of emotionally biased and unbiased sentences that randomly led to highly expected or unexpected word outcomes. Unexpected outcomes (as determined by sentence completion written tests) elicited significantly larger N400 and pN400FP responses than did highly expected outcomes. Emotionally neutral outcomes triggered a significant N400 expectancy effect across all scalp locations, including frontal sites, whereas emotionally biased outcomes elicited a significant N400 effect localized to posterior scalp regions. The subsequent pN400FP effect was significant only when emotional expectations were violated and not when emotionally neutral sentences led to unexpected outcomes. This frontal effect, linked to the processing of lexically unexpected but plausible words, showed larger amplitudes for unexpected pleasant surprises than for unexpected setbacks. Our results support the view that the pN400FP response to unexpected verbal outcomes entails more than a generic reaction to a lexical misprediction. Rather, they favour the hypothesis that the affective content of the sentence being processed influences the effort needed to override a lexical prediction, such that more effort is needed to override a pessimistic prediction than an optimistic one.Publicación Please be logical, I am in a bad mood: An electrophysiological study of mood effects on reasoning(Elsevier, 2019-04) Rodríguez Gómez, Pablo; Pozo García, Miguel Ángel; Hinojosa, José Antonio; Moreno Bella, EvaSeveral behavioral studies have reported a detrimental effect of emotion on reasoning tasks, either when the content of the reasoning and/or the mood state of the individual are emotionally loaded. However, the neural mechanisms involved in this phenomena remain largely unexplored. In an event-related potentials (ERPs) study, we examined the consequences of an induced mood over the electrophysiological signals obtained while processing logical and illogical categorical conclusions. Prior to performing a syllogism reading task, we aimed to induce, by using short film clips, high arousal negative and positive moods and neutral affective states to participants in three separate recording sessions. Our mood induction procedure was only successful at inducing a highly arousing negative state. Behaviorally, participants committed more errors overall while judging the invalidity versus the validity of illogical and logical conclusions, respectively, but no influences from mood state emerged at this logical validity task. Electrophysiologically and overall a negative going N400 deflection was larger for illogical relative to logical conclusions in a parietal region between 300 and 420 ms. However, further analysis revealed that the logical conclusions were only more expected (smaller N400 amplitudes) in the negative relative to the neutral and the positive sessions, providing support to theoretical views that posit that a more analytic reasoning style might be implemented under a negative mood state. These results provide further electrophysiological evidence of the influence of mood on other cognitive processes, particularly on the anticipation and processing of logical conclusions during online reasoning tasks.Publicación Event-related potentials (ERPs) in the study of bilingual language processing(Elsevier, 2018-11) Rodríguez Fornells, Antoni; Laine, Matti; Moreno Bella, EvaThe present review focuses on event-related potential (ERP) studies that have addressed two fundamental issues in bilingualism research, namely the processing of a first versus a second language in the bilingual brain and the issue of control of two languages. A major advantage of the ERP technique is its high temporal resolution that enables the study of task-related neural activity at the millisecond level. For example, ERP studies of bilingualism have shown that developmental changes in the ability to discriminate native and foreign speech sounds can experimentally be traced by the presence or absence of a specific ERP component (the mismatch negativity). They have also revealed latency delays in a semantic-related ERP component (the N400) in bilinguals compared to monolinguals, as well as in bilinguals reading in their L1 or L2 language. These studies have also highlighted the importance of L2 proficiency level and age of acquisition on bilingual language processing. Moreover, ERP studies have pointed out potential mechanisms of avoidance of interference between languages (the NoGo N200 effect). The present review aims to describe and integrate the main results of the selected ERP studies on bilingualism and to provide an overview of how different ERP components can be used to address important theoretical questions in this field. Finally, we suggest potential research directions to clarify unresolved issues and to advance this emerging field of research.Publicación Can Bilinguals See It Coming? Word Anticipation in L2 Sentence Reading(American Psychological Association, 2014) Foucart, Alice; Martin, Clara D.; Costa, Albert; Moreno Bella, EvaWhy is it more difficult to comprehend a 2nd (L2) than a 1st language (L1)? In the present article we investigate whether difficulties during L2 sentence comprehension come from differences in the way L1 and L2 speakers anticipate upcoming words. We recorded the brain activity (event-related potentials) of Spanish monolinguals, French-Spanish late bilinguals, and Spanish-Catalan early bilinguals while reading sentences in Spanish. We manipulated the ending of highly constrained sentences so that the critical noun was either expected or not. The expected and unexpected nouns were of different gender so that we could observe potential anticipation effects already on the article. In line with previous studies, a modulation of the N400 effect was observed on the article and the noun, followed by an anterior positivity on the noun. Importantly, this pattern was found in all 3 groups, suggesting that, at least when their 2 languages are closely related, bilinguals are able to anticipate upcoming words in a similar manner as monolinguals.Publicación Will the glass be half full or half empty? Brain potentials and emotional expectations(Elsevier, 2011) Vázquez, Carmelo; Moreno Bella, EvaBrainwave responses to words in context depend on semantic and world-knowledge expectations. Using the N400 component of event-related potentials as an index of word expectation, we explored brain responses tonegatively and positively biased sentence frames randomly presented withtheir emotionally matched highly expected outcome or with violations that included switches to unexpected emotionally opposite outcomes or nonsense. Nonsense elicited large N400 responses regardless of the bias of the preceding sentence frame. Unexpected emotionally opposite outcomes elicited smaller than nonsense N400 responses and subsequent post-N400 frontal positivities, both unaffected by sentence frame bias. Over a midline-posterior scalp region, expected positive outcomes elicited larger N400 responses than negative ones, despite a high and matched word probability. Our study reveals that brains respond to unexpected emotional outcomes regardless of the direction of the emotional switch and hints at the possibility that the strength of positive and negative expectations may be adjusted before experiencing unexpected events.Publicación Switching Languages, Switching Palabras (Words): An Electrophysiological Study of Code Switching(Elsevier, 2002-02) Federmeier, Kara D.; Kutas, Marta; Moreno Bella, EvaSwitching languages has often been associated with a processing cost. In this study, the authors used event-related potentials to compare switches between two languages with within-language lexical switches as bilinguals read for comprehension. Stimuli included English sentences and idioms ending either with the expected English words, their Spanish translations (code switches), or English synonyms (lexical switches). As expected, lexical switches specifically enhanced the N400 response in both context types. Code switches, by contrast, elicited an increased negativity over left fronto-central sites in the regular nonidiomatic sentences (250–450 ms) and a large posterior positivity (450–850 ms) in both context types. In addition, both lexical and code switches elicited a late frontal positivity (650–850 ms) relative to expected completions, especially in idioms. Analysis of the individual response patterns showed correlations with vocabulary skills in English and in Spanish. Overall, the electrophysiological data suggest that for some speakers in some contexts, the processing of a code switch may actually be less costly than the processing of an unexpected within-language item.Publicación When logical conclusions go against beliefs: an ERP study(Elsevier, 2018) Rodríguez Gómez, Pablo; Rincón Pérez, Irene; Santaniello, Gerardo; Poch, Claudia; Pozo García, Miguel Ángel; Hinojosa, José Antonio; Moreno Bella, EvaReasoning is a fundamental human ability, vulnerable to error. According to behavioural measures, we are biased to consider valid the conclusion of an argument based on the veracity of the conclusion itself rather than on the formal logic of the argument. Nowadays, brain imaging techniques can be used to explore peoplés responses as they reason with linguistic materials. Using the Event-Related Potential technique in a categorical syllogism reading task, an N400 enhancement was found for the processing of invalid conclusions preceded by true premises (e.g. All men are mortal). By contrast, when initial premises consisted of socially prejudiced statements previously rated as false (e.g. All blond girls are dumb), valid rather than invalid conclusions enhanced the N400 response. Considering what the modulation of N400 indexes (i.e. word anticipation processes), our data suggests that people cannot follow the logic of an argument to anticipate upcoming words if they clash with veracity.Publicación Anticipating Words and Their Gender: An Event-related Brain Potential Study of Semantic Integration, Gender Expectancy, and Gender Agreement in Spanish Sentence Reading(MIT Press Direct, 2004-09) Wicha, Nicole; Kutas, Marta; Moreno Bella, EvaRecent studies indicate that the human brain attends to and uses grammatical gender cues during sentence comprehension. Here, we examine the nature and time course of the effect of gender on word-by-word sentence reading. Eventrelated brain potentials were recorded to an article and noun, while native Spanish speakers read medium- to high-constraint Spanish sentences for comprehension. The noun either fit the sentence meaning or not, and matched the preceding article in gender or not; in addition, the preceding article was either expected or unexpected based on prior sentence context. Semantically anomalous nouns elicited an N400. Genderdisagreeing nouns elicited a posterior late positivity (P600), replicating previous findings for words. Gender agreement and semantic congruity interacted in both the N400 window—with a larger negativity frontally for double violations—and the P600 window—with a larger positivity for semantic anomalies, relative to the prestimulus baseline. Finally, unexpected articles elicited an enhanced positivity (500–700 msec post onset) relative to expected articles. Overall, our data indicate that readers anticipate and attend to the gender of both articles and nouns, and use gender in real time to maintain agreement and to build sentence meaning.
