Bilingualism has been shown to contribute to increased resilience against cognitive aging. One of the key brain structures linked to memory and dementia symptom onset, the hippocampus, has been observed to adapt in response to bilingual experience – at least in healthy individuals. However, in the context of neurodegenerative pathology, it is yet u...

Background: Using a foreign language can influence emotion modulation, but whether different psychotherapy processes would be affected by a foreign language is still unclear. The current study explored the foreign language effect on the extinction of fear. Method: During the conditioning phase, part of the neutral stimuli presented to the partic...

Bilinguals who switch from a monolingual context to a bilingual context enhance their domain-general attentional system. But what drives the adaptation process and translates into the observed increased efficiency of the attentional system? To uncover the origin of the plasticity in a bilingual’s language experience, we investigated whether switchi...

Two experimental studies were conducted to replicate the effect found by Baus et al. where language as a marker of social categories affected recognition of faces in an old/new paradigm. In Study 1, we presented faces along with utterances in Swedish and in English to native Swedish speakers. Faces presented along with Swedish utterances were not r...

Does language categorization influence face identification? The present study addressed this question by means of two experiments. First, to establish language categorization of faces, the memory confusion paradigm was used to create two language categories of faces, Spanish and English. Subsequently, participants underwent an oddball paradigm, in...

Our preferences and evaluations are often affected by contextual factors. One unavoidable context is language. We used an evaluative conditioning (EC) paradigm (pairing neutral stimuli with emotional or neutral stimuli) to investigate whether our evaluations are equally conditioned in a first (L1) and a second language (L2). An EC effect was observ...

The present study aimed to explore the bilingual disadvantage in the course of speech production by comparing the naming performance and the temporal dynamics of object naming in three groups of participants: monolinguals, L1 bilinguals and L2 bilinguals. To determine the origin of the bilingual disadvantage, whether lexical or post-lexical, we man...

Lifelong bilingualism may contribute to cognitive reserve (CR) in neurodegenerative diseases as shown by a delay of the age at symptom onset in bilinguals with Alzheimer’s disease (AD) and Mild Cognitive Impairment (MCI). However, some studies have failed to show this bilingual advantage, suggesting that it might depend on the type and degree of bi...

The extent to which negative bias toward foreign‐accented speakers originates from social categorization (in‐group/out‐group categorization) and/or from processing fluency (ease in processing information) is not clear. Some have argued that accent first induces a social identity effect and that processing fluency later modifies the impact of this e...

Background: Evidence from previous studies suggests that bilingualism contributes to cognitive reserve because bilinguals manifest the first symptoms of Alzheimer's disease (AD) up to 5 years later than monolinguals. Other cross-sectional studies demonstrate that bilinguals show greater amounts of brain atrophy and hypometabolism than monolinguals...

This paper reports an experiment designed to assess the occurrence of lexical interference in verb production in Spanish. Using the semantic competitors paradigm (HOWARD et al., 2006), we show that the higher the number of verbs of the same category produced, the longer it takes to retrieve another verb of the same category in a picture naming task...

Este artículo presenta un experimento diseñado para evaluar la ocurrencia de interferencia léxica en la producción de verbos en español. Usando el paradigma de los competidores semánticos (HOWARD et al., 2006), mostramos que cuanto mayor es el número de verbos de la misma categoría producidos, más tiempo lleva recuperar otro verbo de la misma categ...

Background: Patients with the semantic variant of Primary Progressive Aphasia (svPPA) offer a unique opportunity to study the relationship between lexical retrieval and semantics, as they are characterised by progressive degradation of central semantic representations. However, there are few studies of how lexical retrieval across languages is affe...

Word reduction refers to how predictable words are shortened in features such as duration, intensity, or pitch. However, its origin is still unclear: Are words reduced because it is the second time that conceptual representations are activated, or because words are articulated twice? If word reduction is conceptually driven, it would be irrelevant...

In the past years, there has been a significant increase in the number of people learning sign languages. For hearing second language (L2) signers, acquiring a sign language involves acquiring a new language in a different modality. Exploring how L2 sign perception is accomplished and how newly learned categories are created is the aim of the prese...

More cognitive resources are required to comprehend foreign-accented than native speech. Focusing these cognitive resources on resolving the acoustic mismatch between the foreign-accented input and listeners’ stored representations of spoken words can affect other cognitive processes. Across two studies, we explored whether processing foreign-accen...

Our preferences and evaluations are often affected by contextual factors. One unavoidable context is language. We used an evaluative conditioning (EC) paradigm (pairing neutral stimuli with emotional or neutral stimuli) to investigate whether our evaluations are equally conditioned in a native (NL) and in a foreign language (FL). An EC effect was o...

Individuals with aphasia frequently show lexical retrieval deficits due to increased interference of semantically related competitors, a phenomenon that can be observed in tasks such as naming pictures grouped by semantic category. These deficits are explained in terms of impaired semantic control, a set of abilities that are to some extent depende...

The use of socially opprobrious words (taboo words) is a cross-cultural phenomenon occurring between in- dividuals from almost all social extractions. The neurocognitive correlates of using taboo words in the native language (L1) as compared to their use in a second (L2) language are largely unknown. We used fMRI to in- vestigate the processing of...

This study investigates the relationship between mechanisms involved in language control within dual- and single-language contexts by examining whether they are similarly impaired in bilingual PD patients. To do so, we explored the performance of bilingual individuals affected by PD and healthy controls on two linguistic tasks: between-language and...

We investigated the neural correlates of accented speech processing (ASP) with an fMRI study that overcame prior limitations in this line of research: we preserved intelligibility by using two regional accents that differ in prosody but only mildly in phonetics (Latin American and Castilian Spanish), and we used independent component analysis to id...

We tested whether learning associated to lexical selection is error-based, and whether lexical selection is competitive by assessing the after-effects of producing words on subsequent production of semantic competitors differing in degree of error (translation equivalents). Speakers named pictures or words in one language (part A), and then named t...

This chapter reviews current knowledge about the relationship between language control and executive control (EC) mechanisms in bilingual speakers. The most common strategy to assess the relationship between the two domains of control is to compare people's performance on control tasks that involve linguistic and non‐linguistic processes. The chapt...

Odor naming is enhanced in communities where communication about odors is a central part of daily life (e.g., wine experts, flavorists, and some hunter‐gatherer groups). In this study, we investigated how expert knowledge and daily experience affect the ability to name odors in a group of experts that has not previously been investigated in this co...

Syntactic priming in language production is the increased likelihood of using a recently encountered syntactic structure. In this paper, we examine two theories of why speakers can be primed: error‐driven learning accounts (Bock, Dell, Chang, & Onishi, 2007; Chang, Dell, & Bock, 2006) and activation‐based accounts (Pickering & Branigan, 1999; Reitt...

If you are kind to me, I am likely to reciprocate and doing so feels fair. Many theories of social exchange assume that such reciprocity and fairness are well aligned with one another. We argue that this correspondence between reciprocity and fairness is restricted to interpersonal dyads and does not govern more complex multilateral interactions. W...

The present study investigated language inhibition and cross-language interference as two possible mechanisms of bilingual language control (BLC) that can be affected by Huntington’s disease (HD), a neurodegenerative disease (ND) affecting the striatum. To this aim, the study explored the performance of pre-symptomatic and early-stage HD patients i...

What is the relationship between bilingual language control (BLC) mechanisms and domain-general executive control (EC) processes? Do these two domains share some of their mechanisms? Here, we take a novel approach to this question, investigating whether short-term language switching training improves non-linguistic task switching performance. Two g...

Language context (native vs. foreign) affects people’s choices and preferences in a wide variety of situations. However, emotional reactions are a key component driving people’s choices in those situations. In six studies, we test whether foreign language context modifies biases and the use of heuristics not directly caused by emotional reactions....

How are the two lexicons of a bilingual represented and how do they interact during language processing? These questions are central to bilingualism and have been the topics of a large number of studies. Dijkstra, Wahl, Buytenhuijs, van Halem, Al-jibouri, De Korte & Rekke (in press) put forward a model that tries to capture people's behavior in sev...

Theories of dishonest behavior implicitly assume language independence. Here, we investigated this assumption by comparing lying by people using a foreign language versus their native tongue. Participants rolled a die and were paid according to the outcome they reported. Because the outcome was private, they could lie to inflate their profit withou...

Bilingual speakers are suggested to use control processes to avoid linguistic interference from the unintended language. It is debated whether these bilingual language control (BLC) processes are an instantiation of the more domain-general executive control (EC) processes. Previous studies inconsistently report correlations between measures of ling...

Ikizer and Ramirez-Esparza (2017) reported a study suggesting that bilingualism may have a positive impact on people's social skills. They found that a) bilinguals scored higher on a scale that is supposed to reveal social flexibility, and that b) they also report having social interactions more frequently than monolinguals. The authors relate this...

Acquiring and speaking a second language increases demand on the processes of language control for bilingual as compared to monolingual speakers. Language control for bilingual speakers involves the ability to keep the two languages separated to avoid interference and to select one language or the other in a given conversational context. This abili...

For everyday communication, bilingual speakers need to face the complex task of rapidly choosing the most appropriate language given the context, maintaining this choice over the current communicative act, and shielding lexical selection from competing alternatives from non-target languages. Yet, speech production of bilinguals is typically flawles...

The information we obtain from how speakers sound-for example their accent-affects how we interpret the messages they convey. A clear example is foreign accented speech, where reduced intelligibility and speaker's social categorization (out-group member) affect memory and the credibility of the message (e.g., less trustworthiness). In the present s...

Emotions are at the core of human nature. There is evidence that emotional reactivity in foreign languages compared to native languages is reduced. We explore whether this emotional distance could modulate fear conditioning, an essential mechanism for the understanding and treatment of anxiety disorders. A group of participants was verbally informe...

How flexible is bilingual language control and how does it adapt to the linguistic context of a conversation? We address this by looking at the pattern of switch costs in contexts involving mostly the use of a dominant or non-dominant language. This linguistic context affected switching patterns: switching was equally costly for both languages in a...

We explore the origin of the foreign language effect on moral judgements by assessing whether language context alters the weight given to intentions and outcomes during moral judgement. Specifically, we investigated whether foreign language contexts, compared with native ones, may lead people to focus more on the outcomes of an action and less on t...

People consider choices that involve risk on a daily basis. In principle, willingness to take risks should be independent of the language used while considering the available options. However, research has shown that using a foreign language can increase willingness to take risks, presumably because a foreign language is less emotional. Here, we in...

The role of the anterior cingulate cortex (ACC) in modulating the effect of bilingual experience on cognitive control has been reported at both functional and structural neural levels. Individual differences in the ACC sulcal patterns have been recently correlated with cognitive control efficiency in monolinguals. We aimed to investigate whether di...

Cognitive processing requires the ability to flexibly integrate and process information across large brain networks. More information is needed on how brain networks dynamically reorganize to allow such broad communication across many different brain regions in order to integrate the necessary information. Here, we use intracranial EEG to record ne...

We explore the properties of foreigner talk through word reduction. Word reduction signals that the speaker is referring to the same entity as previously and should be preserved for foreigner talk. However, it leads to intelligibility loss, which works against foreigner talk. Pairs of speakers engaged in a task where native speakers talked either t...

Foreign languages are often learned in emotionally neutral academic environments which differ greatly from the familiar context where native languages are acquired. This difference in learning contexts has been argued to lead to reduced emotional resonance when confronted with a foreign language. In the current study, we investigated whether the re...

Language production models typically assume that retrieving a word for articulation is a sequential process with substantial functional delays between conceptual, lexical, phonological and motor processing, respectively. Nevertheless, explicit evidence contrasting the spatiotemporal dynamics between different word production components is scarce. H...

Would you kill one person to save five? People are more willing to accept such utilitarian action when using a foreign language than when using their native language. In six experiments, we investigated why foreign-language use affects moral choice in this way. On the one hand, the difficulty of using a foreign language might slow people down and i...

We investigated whether it is possible to study the network dynamics and the anatomical regions involved in the earliest moments of picture naming by using invasive electroencephalogram (EEG) traces to predict naming errors. Four right-handed participants with focal epilepsy explored with extensive stereotactic implant montages that recorded tempor...

Una fascinante aproximación al funcionamiento del bilingüismo en el cerebro humano y cómo este adquiere y procesa el lenguaje. Todos estamos interesados en el lenguaje y nos hemos preguntado alguna vez cómo el cerebro humano lo adquiere y procesa. Pero, ¿cómo conviven dos lenguas en un mismo cerebro y qué implicaciones tiene esa convivencia? Para...

Here we investigated how the language in which a person addresses us, native or foreign, influences subsequent face recognition. In an old/new paradigm, we explored the behavioral and electrophysiological activity associated with face recognition memory. Participants were first presented with faces accompanied by voices speaking either in their nat...

Recent research has revealed that people’s preferences, choices, and judgments are affected by whether information is presented in a foreign or a native language. Here, we review this evidence, focusing on various decision-making domains and advancing a variety of potential explanations for this foreign-language effect on decision making. We interp...

This article proposes that syntactic features of newscasts can act as learned motivational stimuli determining both viewers’ attention and memory for information. An experiment was conducted in which we manipulated the presence of stings (a type of widely used audiovisual connector) and the arousal levels of stories, while participants’ attention a...

Though moral intuitions and choices seem fundamental to our core being, there is surprising new evidence that people resolve moral dilemmas differently when they consider them in a foreign language (Cipolletti et al., 2016; Costa et al., 2014a; Geipel et al., 2015): People are more willing to sacrifice 1 person to save 5 when they use a foreign lan...

In one task-switching experiment, we compared bilinguals and monolinguals to explore the reliability of the bilingualism effect on the n-2 repetition cost. In a second task-switching experiment, we tested another group of bilinguals and monolinguals and measured both the n-1 shift cost and the n-2 repetition cost to test the hypothesis that bilingu...

We frequently experience and successfully process anomalous utterances. Here we examine whether people do this by ‘correcting’ syntactic anomalies to yield well-formed representations. In two structural priming experiments, participants’ syntactic choices in picture description were influenced as strongly by previously comprehended anomalous (missi...

Most models of lexical access assume that bilingual speakers activate their two languages even when they are in a context in which only one language is used. A critical piece of evidence used to support this notion is the observation that a given word automatically activates its translation equivalent in the other language. Here, we argue that thes...

A growing literature demonstrates that using a foreign language affects choice. This is surprising because if people understand their options, choice should be language independent. Here, we review the impact of using a foreign language on risk, inference, and morality, and discuss potential explanations, including reduced emotion, psychological di...

One of the most remarkable abilities of bilingual speakers is that of keeping their two languages apart during speech production. Several researchers have argued that the attentional mechanisms responsible for this ability may vary depending on the L2-proficiency achieved by the bilinguals (Green, 1986; Costa & Santesteban, 2004). Here we use a lan...

Early linguistic experience has an impact on the way we decode audiovisual speech in face-to-face communication. The present study examined whether differences in visual speech decoding could be linked to a broader difference in face processing. To identify a phoneme we have to do an analysis of the speaker’s face to focus on the relevant cues for...

During picture naming, the ease with which humans generate words is dependent upon the context in which they are named. For instances, naming previously presented items results in facilitation. Instead, naming a picture semantically related to previous items displays persistent interference effects (i.e., cumulative semantic interference, CSI). The...

We explored the overlap between bilingual language control (bLC) and domain-general executive control (EC) by focusing on inhibitory control processes. We tested 62 bilinguals in linguistic and non-linguistic switching tasks for two types of costs, such as the n-1 shift cost and the n-2 repetition cost. In order to explore the involvement of inhibi...

Native speakers are sensitive to the frequencies of multiword phrases: they are faster to process higher frequency phrases, after controlling for all part frequencies (e.g. high: Don't have to worry vs. low: Don't have to wait). Here, we ask whether intermediate-advanced late (English) learners are also sensitive to the distributional properties of...

Listeners are able to anticipate upcoming words during sentence comprehension, and, as a result, theyalso pre-activate semantically related words. In the present study, we aim at exploring whether theseanticipatory processes are modulated by indexical properties of the speakers, such as a speaker's accent.Event-related brain potentials were obtaine...

Obtaining a neurophysiology of language production is a complex endeavour which, at present, is in its “infancy”. It will require the integration of long-standing psycholinguistic models and phenomena with the anatomical and dynamical constraints of neural coding. In our target article [Strijkers, K., & Costa, A. (2016). The cortical dynamics of sp...

In this study we explore whether world knowledge (WK) processing differs between individuals listening to their native (L1) or their non-native (L2) language. We recorded event-related brain potentials in L1 and L2 speakers of Spanish while they listened to sentences uttered by native speakers of Spanish. Sentences were either congruent or incongru...

A central question in the cognitive neuroscience of language production concerns the cortical activation time-course by which different word production components become available to the speaker. According to the dominant neurocognitive model of word production, this is achieved in a sequential fashion where each of the linguistic components involv...

The understanding of the nature of the control abilities in the context of bilingual language production is now a hot research topic. Indeed, the improvement of our knowledge about this issue would offer the possibility to explain the patterns of language impairments in terms of control deficits. One way to look at this is to investigate the intera...

Bilinguals have been shown to perform worse than monolinguals in a variety of verbal tasks. This study investigated this bilingual verbal cost in a large-scale picture-naming study conducted in Spanish. We explored how individual characteristics of the participants and the linguistic properties of the words being spoken influence this performance c...

Native speakers with different linguistic backgrounds differ in their usage of language, and particularly in their vocabulary. For instance, British natives would use the word "holiday" when American natives would prefer the word "vacation". This study investigates how cross-dialectal lexical variation impacts lexical processing. Electrophysiologic...

In order to study the difficulties experienced during sentence comprehension in a foreign language (L2), we investigated semantic and world knowledge information retrieval in L2 comprehenders. Event-related potentials (ERP) were collected in late learners of English whose native language is Spanish, performing a sentence reading task in English. We...
