Publicación Effects of transient, mild mood states on semantic memory organization and use: an event-related potential investigation in humans(Elsevier, 2001-06) Federmeier, Kara D.; Kirsonb, Donald A.; Kutas, Marta; Moreno Bella, EvaThe effects of transient mood states on semantic memory organization and use were investigated using event-related potentials. Participants read sentence pairs ending with (1) the most expected word, (2) an unexpected word from the expected semantic category, or (3) an unexpected word from a different (related) category; half the pairs were read under neutral mood and half under positive mood. Under neutral mood, N400 amplitudes were smallest for expected items and smaller for unexpected items when these came from the expected category. In contrast, under positive mood, N400 amplitudes to the two types of unexpected items did not differ. Positive mood seemed to speci®cally facilitate the processing of distantly-related, unexpected items. The results suggest that transient mood states are associated with dynamic changes in how semantic memory is used on-line.Publicación 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 Syntactic expectancy: an event-related potentials study(Elsevier, 2005-04-11) Hinojosa, José Antonio; Casado, Pilar; Pozo García, Miguel Ángel; Moreno Bella, Eva; Muñoz Ibáñez, Francisco JavierAlthough extensive work has been conducted in order to study expectancies about semantic information, little effort has been dedicated to the study of the influence of expectancies in the processing of forthcoming syntactic information. The present study tries to examine the issue by presenting participants with grammatically correct sentences of two types. In the first type the critical word of the sentence belonged to the most expected word category type on the basis of the previous context (an article following a verb). In the second sentence type, the critical word was an unexpected but correct word category (an article following an adjective) when a verb is highly expected. Event-related potentials (ERPs) were measured to critical words in both sentence types. Brain waves evoked by the correct but syntactically unexpected word revealed the presence of a negativity with a central distribution around 300–500 ms after stimuli onset, an N400, that was absent in the case of syntactically expected words. No differences were present in previous time windows. These results support models that differentiate between the processing of expected and unexpected syntactic structures.Publicación Potato not Pope: human brain potentials to gender expectation and agreement in Spanish spoken sentences(Elsevier, 2003-08-07) Wicha, Nicole; Bates, Elizabeth A.; Kutas, Marta; Moreno Bella, EvaEvent-related potentials were used to examine the role of grammatical gender in auditory sentence comprehension. Native Spanish speakers listened to sentence pairs in which a drawing depicting a noun was either congruent or incongruent with sentence meaning, and agreed or disagreed in gender with the immediately preceding spoken article. Semantically incongruent drawings elicited an N400 regardless of gender agreement. A similar negativity to prior articles of gender opposite to that of the contextually expected noun suggests that listeners predict specific words during comprehension. Gender disagreements at the drawing also elicited an increased negativity with a later onset and distribution distinct from the canonical N400, indicating that comprehenders attend to gender agreement, even when one of the words is only implicitly represented by a drawing.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.Publicación Affective neurolinguistics: towards a framework for reconciling language and emotion(Taylor & Francis, 2020) Hinojosa, José Antonio; Ferré Romeu, María Pilar; Moreno Bella, EvaStandard neurocognitive models of language processing have tended to obviate the need for incorporating emotion processes, while affective neuroscience theories have typically been concerned with the way in which people communicate their emotions, and have often simply not addressed linguistic issues. Here, we summarise evidence from temporal and spatial brain imaging studies that have investigated emotion effects on lexical, semantic and morphosyntactic aspects of language during the comprehension of single words and sentences. The evidence reviewed suggests that emotion is represented in the brain as a set of semantic features in a distributed sensory, motor, language and affective network. Also, emotion interacts with a number of lexical, semantic and syntactic features in different brain regions and timings. This is in line with the proposals of interactive neurocognitive models of language processing, which assume the interplay between different representational levels during on-line language comprehension.Publicación Processing semantic anomalies in two languages: an electrophysiological exploration in both languages of Spanish–English bilinguals(Elsevier, 2005) Kutas, Marta; Moreno Bella, EvaThe latency of the brain response to semantic anomalies (N400 effect) has been found to be longer in a bilingual’s second language (L2) than in their first language (L1) and/or to that seen in monolinguals. This has been explained in terms of late exposure to L2, although age of exposure and language proficiency are often highly correlated. We thus examined the relative contributions of these factors not only in L2 but also in L1 in a group of Spanish–English bilinguals for whom age of exposure and language proficiency were not highly correlated by recording event-related brain potentials (ERPs) to semantically congruous/incongruous words completing written sentences. We also divided our bilinguals into a Spanish-dominant subset who had late exposure and reduced vocabulary proficiency [as measured by Boston Naming Test (BNT) and Verbal Fluency Scores] in L2 (English) relative to L1 (Spanish) and an English-dominant group who had early exposure to both their languages although greater proficiency in English than in Spanish. In both groups, the N400 effect was significantly later in the nondominant than the dominant language. Although this slowing could be due to late exposure to English in the Spanish-dominant group, late exposure cannot explain the slowing in Spanish in the English-dominant group. Overall, we found that vocabulary proficiency and age of exposure are both important in determining the timing of semantic integration effects during written sentence processing—with vocabulary proficiency predicting the timing of semantic analysis in L1 and both age of exposure and language proficiency, although highly correlated, making additional small but uncorrelated contributions to the speed of semantic analysis/ integration in L2Publicación 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 Facing stereotypes: ERP responses to male and female faces after gender-stereotyped statements(Oxford University Press, 2020-09) Rodríguez Gómez, Pablo; Romero Ferreiro, Verónica; Pozo García, Miguel Ángel; Hinojosa, José Antonio; Moreno Bella, EvaDespite gender is a salient feature in face recognition, the question of whether stereotyping modulates face processing remains unexplored. Event-related potentials from 40 participants (20 female) was recorded as male and female faces matched or mismatched previous gender-stereotyped statements and were compared with those elicited by faces preceded by gender-unbiased statements. We conducted linear mixed-effects models to account for possible random effects from both participants and the strength of the gender bias. The amplitude of the N170 to faces was larger following stereotyped relative to gender-unbiased statements in both male and female participants, although the effect was larger for males. This result reveals that stereotyping exerts an early effect in face processing and that the impact is higher in men. In later time windows, male faces after female-stereotyped statements elicited large late positivity potential (LPP) responses in both men and women, indicating that the violation of male stereotypes induces a post-perceptual reevaluation of a salient or conflicting event. Besides, the largest LPP amplitude in women was elicited when they encountered a female face after a female-stereotyped statement. The later result is discussed from the perspective of recent claims on the evolution of women self-identification with traditionally held female roles.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.
