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 Are you interested in economic inequality? Depends on where you live(Wiley, 2022) Sánchez‐Rodríguez, Ángel; Moreno Bella, EvaAlthough several scholars and international institutions have considered high levels of economic inequality an issue for society, the populations who live in more unequal countries tend to be less concerned about it. Given the ideological connotations in the construct of people’s concerns about economic inequality, whether those who live in more unequal countries are more interested in economic inequality remains unclear. In this research, we aimed to examine whether objective economic inequality is related to individuals’ interest in the topic of economic inequality. First, we used data from the United States Census Bureau and Google Trends to examine whether the objective level of economic inequality predicted the interest of the population in searching Google for terms such as “economic inequality” and “income inequality.” Our results showed that individuals who live in more economically unequal U.S. states more often search these terms. Second, we analysed the tweets that contained the terms “economic inequality” and “income inequality” (10,118 tweets) published over 9 days and localised by U.S. state. We found that individuals who live in more economically unequal U.S. states more often post tweets about economic and income inequality. To take a closer look at the narrative around economic/income inequality, we conducted a network analysis using tweets as nodes and retweets as edges. Our results suggest that the public narrative about economic inequality via Twitter was built on three large communities. Finally, we discuss the implications of our results in relation to economic inequality consequences.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 What about diversity? The effect of organizational economic inequality on the perceived presence of women and ethnic minority groups(Public Library of Science, 2022) Kulich, Clara; Willis, Guillermo B.; Moya, Miguel; Moreno Bella, EvaEconomic inequality shapes the degree to which people and different social groups are perceived in stereotypical ways. Our research sought to investigate the impact of the perception of economic inequality in an organizational setting on expectations of social diversity in the organization’s workforce, across the dimensions of gender and ethnicity. Combining data from previous experiments, we first explored in one set of studies (Studies 1a and 1b; N = 378) whether the degree of economic inequality in a fictitious organization affected participants’ expectations of the representation of minority vs. majority group employees. We found that when we presented an organization with unequal (vs. equal) distribution of economic wealth amongst its employees to study participants, they expected the presence of men and White majority individuals to be larger than the presence of women and ethnic minorities. Second, we tested our hypotheses and replicated these initial effects in a pre-registered study (Study 2: N = 449). Moreover, we explored the potential mediating role of perceived diversity climate, that is, the perception that the organization promotes and deals well with demographic diversity. Findings revealed that an organizational setting that distributed resources unequally (vs. equally) was associated with a more adverse diversity climate, which, in turn, correlated with expectations of a lower presence of minority group employees in the organization. We concluded that economic inequality creates a context that modulates perceptions of a climate of social exclusion which likely affects the possibilities for members of disadvantaged groups to participate and develop in organizations.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 ‘Congratulations for your day’: benevolent attitudes during March 8 in Mexico(Taylor & Francis, 2023-01-02) Quiroga Garza, Angélica; Matamoros Lima, Juan A.; Willis, Guillermo B.; Moreno Bella, EvaSexist attitudes reinforce gender inequality, but, are they absent on Women’s Day? This research examines the extent to which, in some contexts, Women’s Day can activate sexist attitudes that reinforce structural inequalities between men and women. Based on ambivalent sexism theory, we propose that people are more likely to agree with benevolent sexist attitudes on Women’s Day than on any other day. In Study 1 (N=190) we measured sexist attitudes on Women’s Day and then one month later. We found that participants asked on Women’s Day reported more benevolent sexism than participants asked a month later. Benevolent sexism was stronger on Women’s Day for men (who scored higher for both hostile and benevolent sexism than women). In order to establish causality, in Study 2 (N=175) we used an experimental paradigm in which we made Women’s Day more salient (against the control condition). Results showed that participants assigned to the Women’s Day experimental condition indicated more support for benevolent sexist attitudes than those assigned to the control condition and again (men scored higher on both dimensions of sexism across both conditions). This research provides evidence of the potential unintended effects of International Women’s Day and the challenges that women still face.Publicación Economic inequality and masculinity–femininity: The prevailing perceived traits in higher unequal contexts are masculine.(2019) Willis, Guillermo B.; Moya, Miguel; Moreno Bella, EvaPrevious studies have shown that economic inequality influences psychological processes. In this article, we argue that economic inequality also makes masculine attributes more prototypical. In Study 1 (N = 106), using an experimental design, we showed that individuals belonging to a society characterized by a higher level of economic inequality are perceived as more masculine than feminine. Study 2 (N = 75) shows, also experimentally, that the upper social class is perceived mostly in terms of masculine traits, and that this effect is greater when economic inequality is relatively high. Conversely, the lower social class is more clearly perceived in terms of feminine traits. These results inform our understanding of the impact of economic inequality on social perception.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 Expecting Gender: An Event Related Brain Potential Study on the Role of Grammatical Gender in Comprehending a Line Drawing Within a Written Sentence in Spanish(Elsevier, 2003) Wicha, Nicole; Kutas, Marta; Moreno Bella, EvaEvent-related brain potentials (ERPs) were used to examine the role of grammatical gender in written sentence comprehension. Native Spanish speakers read sentences in which a drawing depicting a target noun was either congruent or incongruent with sentence meaning, and either agreed or disagreed in gender with that of the preceding article. The gender-agreement violation at the drawing was associated with an enhanced negativity between 500 and 700 msec post-stimulus onset. Semantically incongruent drawings elicited a larger N400 than congruent drawings regardless of gender (dis)agreement, indicating little effect of grammatical gender agreement on contextual integration of a picture into a written sentence context. We also observed an enhanced negativity for articles with unexpected relative to expected gender based on prior sentence context indicating that readers generate expectations for specific nouns and their articles.Publicación A More Competent, Warm, Feminine, and Human Leader: Perceptions and Effectiveness of Democratic Versus Authoritarian Political Leaders(ADRIPS, 2021-07-12) Torres Vega, Laura C.; Sainz Martínez, Mario; Moreno Bella, EvaNowadays, to the detriment of democratic leaders, the emergence of authoritarian leaders has drastically modified the political sphere. This project aims to shed light on this issue by analysing how the perceived effectiveness of democratic and authoritarian political leaders are shaped by the common dimensions of social perception, such as competence/warmth, masculinity/femininity, and human uniqueness/human nature. Accordingly, three experimental studies were conducted. In Study 1 (n = 1001), we revealed that democratic leaders are perceived as more competent, warm, feminine and human. In Study 2 (n = 548) and Study 3 (n = 622), we investigated whether these dimensions of perception mediated the relationship between leaders and their perceived effectiveness. The results revealed that democratic leaders are perceived as effective in cooperative scenarios due to their competence, femininity, and human nature. Alternatively, democratic leaders are preferred in ambiguous contexts due to their competence and cognitive flexibility, that is, human nature. In contrast, authoritarian leaders are perceived as effective in competitive scenarios because of their masculinity. In Study 3, we manipulated the (in)stability of socio-economic contexts. The results revealed that democratic and authoritarian leaders are perceived as more competent, warm, human and more effective in socio-economic contexts that are stable compared with those that are unstable. The implications of the results regarding the emergence of authoritarian leaders are discussed.
