In Spanish, several analogic instruments are currently available, like the adaptations of the Boston Diagnostic Examination (BDAE), the Western Aphasia Battery (WAB), PALPA, and BETA, which is the most recent tool available. However, these instruments face several validity issues. Here, we introduce Aphasia Cognitive Screening in Spanish (ACS.esp),...
Article
We exploit the phenomenon of cross-modal, cross-language activation to examine the dynamics of language processing. Previous within-language work showed that seeing a sign coactivates phonologically related signs, just as hearing a spoken word coactivates phonologically related words. In this study, we conducted a series of eye-tracking experiments...
Chapter
Knowing at least two languages is ubiquitous in today’s globalized world. Most educational, social, and work settings require fluency in a foreign language. Still, students face immense challenges in learning a foreign language. Interdisciplinary research has revealed some of the linguistic and cognitive aspects underlying language learning success...

Spontaneous, task-free, hemodynamic activity of the brain provides useful information about its functional organization, as it can describe how different brain regions communicate to each other. Neuroimaging studies measuring the spontaneous activity of the brain are conducted while the participants are not engaged in a particular task or receiving...
Article
Reading acquisition is based on a set of preliteracy skills that lay the foundation for future reading abilities. Phonological awareness-the ability to identify and manipulate the sound units of oral language-has been reported to play a central role in reading acquisition. However, current evidence is mixed with respect to its universal contributio...

Full-text available
Bilingual language production requires both language knowledge and language control in order to communicate in a target language. Learning or improving a language in adulthood is an increasingly common undertaking, and this has complex effects on the cognitive and neural processes underlying language production. The current functional magnetic reso...
Preprint
Reading is an evolutionary new development that recruits and tunes brain circuitry connecting visual- and language-processing regions. We investigated the structural correlates of reading and whether genetics influence brain-reading associations. First, we identified left hemisphere cortical surface area (CSA) and cortical thickness (CT) correlates...
Article
Massive and timely screening of the student population for early signs of reading difficulties is needed to implement timely effective remediation of these difficulties. However, traditional approaches are costly and hard to apply. Here we present Lexiland, a tablet-based reading assessment tool for kindergarten and primary school children develope...
Article
Full-text available
Words representing objects (nouns) and words representing actions (verbs) are essential components of speech across languages. While there is evidence regarding the organizational principles governing neural representation of nouns and verbs in monolingual speakers, little is known about how this knowledge is represented in the bilingual brain. To...
Article
Language comprehension depends on the ability to temporally process the periodic structure of the language signal. In this study we investigate temporal processing of Spanish Sign Language (LSE), isolating the specific contribution of signal modality through a comparison with spoken Spanish and the contribution of linguistic status by comparing lan...
Article
Individual differences in infants’ native phonological development have been linked to the quantity and quality of infant‐directed speech (IDS). The effects of parental and infant bilingualism on this relation in 131 five‐ and nine‐month‐old monolingual and bilingual Spanish and Basque infants (72 male; 59 female; from white middle‐class background...
Preprint
Learning a foreign language as an adult is a rewarding but challenging endeavor that entails accruing a massive vocabulary. The literature independently highlights that orthographic similarity and bilingual experience could facilitate foreign vocabulary acquisition. Here, we explored the combined effects of orthographic similarity and bilingual exp...
Chapter
Bi/multilingualism refers to the ability to use two or more languages in everyday life. Increasing interest has been paid to unveil the neural basis of bilingual language processing; however, the brain representation of language in bilinguals is still a matter of debate. Currently, there is a weak level of evidence supporting that the best probable...
Preprint
Bilingual experience may confer advantages in statistical language learning tasks. Given that SL tasks can measure different aspects of foreign language learning, which aspects benefit from bilingual experience is still largely unexplored. Here, we compared a Spanish monolingual and two (Spanish-Basque and Spanish-English) bilingual groups across t...
Article
Full-text available
Significance: Early monolingual versus bilingual experience induces adaptations in the development of linguistic and cognitive processes, and it modulates functional activation patterns during the first months of life. Resting-state functional connectivity (RSFC) is a convenient approach to study the functional organization of the infant brain. RSF...

Full-text available
Behavioral studies have shown that the legibility of handwritten script hinders visual word recognition. Furthermore, when compared with printed words, lexical effects (e.g., word-frequency effect) are magnified for less intelligible (difficult) handwriting (Barnhart & Goldinger, 2010; Perea et al., 2016). This boost has been interpreted in terms o...
Article
Full-text available
Recent evidence suggests that the presence of brain tumors (e.g., low-grade gliomas) triggers language reorganization. Neuroplasticity mechanisms called into play can transfer linguistic functions from damaged to healthy areas unaffected by the tumor. This phenomenon has been reported in monolingual patients, but much less is known about the neurop...

Full-text available
The heated debate regarding bilingual cognitive advantages remains ongoing. While there are many studies supporting positive cognitive effects of bilingualism, recent meta-analyses have concluded that there is no consistent evidence for a ’bilingual advantage’. In this paper we focus on several theoretical concerns. First, we discuss changes in the...

Cortical tracking of linguistic structures in speech, such as phrases (<3 Hz, delta band) and syllables (3–8 Hz, theta band), is known to be crucial for speech comprehension. However, it has not been established whether this effect is related to language proficiency. Here, we investigate how auditory cortical activity in second language (L2) learne...
Article
The grain size of orthographic representations prompted by a consistent orthography (like Spanish or Basque) increases if reading is simultaneously learned in another language with an inconsistent orthography (like French). Here, we aimed to identify item properties that trigger this grain-size accommodation in bilingual reading. Twenty-five French...

Full-text available
Reading typically involves phonological mediation, especially for transparent orthographies with a regular letter to sound correspondence. In this study we ask whether phonological coding is a necessary part of the reading process by examining prelingually deaf individuals who are skilled readers of Spanish. We conducted two EEG experiments exploit...
Article
During reading, we can process and integrate information from words allocated in the parafoveal region. However, whether we extract and process the meaning of parafoveal words is still under debate. Here, we obtained Fixation-Related Potentials in a Basque-Spanish bilingual sample during a Spanish reading task. By using the boundary paradigm, we pr...
Article
Full-text available
Recent evidence suggests that damage to the language network triggers its functional reorganization. Yet, the spectro-temporal fingerprints of this plastic rearrangement and its relation to anatomical changes is less well understood. Here, we combined magnetoencephalographic recordings with a proxy measure of white matter to investigate oscillatory...
Article
Full-text available
Speech comprehension has been proposed to critically rely on oscillatory cortical tracking, that is, phase alignment of neural oscillations to the slow temporal modulations (envelope) of speech. Speech-brain entrainment is readjusted over time as transient events (edges) in speech lead to speech-brain phase realignment. Auditory behavioral research...
Article
Full-text available
The neurocognitive mechanisms that support the generalization of semantic representations across different languages remain to be determined. Current psycholinguistic models propose that semantic representations are likely to overlap across languages, although there is evidence also to the contrary. Neuroimaging studies observed that brain activity...
Article
Full-text available
Functional specialisation and plasticity are fundamental organising principles of the brain. Since the mid-1800s, certain cognitive functions have been known to be lateralised, but the provenance and flexibility of hemispheric specialisation remain open questions. Language is a uniquely human phenomenon that requires a delicate balance between neur...

Cognitive explorations have demonstrated the activation of plastic mechanisms in slow-growing brain lesions, generating structural and functional changes. Due to its incidence, it is essential to investigate the reorganization of functional areas in brain tumor patients as well as formulating new approaches for predicting patient’s quality of life...
Article
Full-text available
Bilingualism is a powerful experiential factor, and its effects have been proposed to extend beyond the linguistic domain by boosting the development of executive functioning skills. Crucially, recent findings suggest that this effect can be detected in bilingual infants before their first birthday indicating that it emerges as a result of early bi...
Article
Numbers and letters are culturally created symbols which are learned through repeated training. This experience leads to a functional specialization of the perceptual system of our brain. Recent evidence suggests a neural dissociation between these two symbols. While previous literature has shown that letters elicit a left lateralized neural respon...
Article
Full-text available
The goal of the paper was to investigate whether morphological units – stems and suffixes – influence orthographic processing by modulating visual attention demands to the task. Orthographic processing was measured with a visual one-back task requiring letters to be detected within pseudowords not including stems/suffixes, or containing real stems...
Preprint
Full-text available
This study examines whether bilingual exposure has a profound effect on the functional organization of the developing human brain during infancy. Recent behavioural research attests that monolingual vs. bilingual experience affects cognitive and linguistic processes already during the first months of life. However, to what extent the intrinsic orga...
Article
Full-text available
How the human brain uses self-generated auditory information during speech production is rather unsettled. Current theories of language production consider a feedback monitoring system that monitors the auditory consequences of speech output and an internal monitoring system, which makes predictions about the auditory consequences of speech before...
Article
Full-text available
Speaking involves coordination of multiple neuromotor systems, including respiration, phonation and articulation. Developing non-invasive imaging methods to study how the brain controls these systems is critical for understanding the neurobiology of speech production. Recent models and animal research suggest that regions beyond the primary motor c...

Article
Indicators of letter frequency and similarity have long been available for Indo-European languages. They have not only been pivotal in controlling the design of experimental psycholinguistic studies seeking to determine the factors that underlie reading ability and literacy acquisition, but have also been useful for studies examining the more gener...

Full-text available
Vocabulary size seems to be affected by multiple factors, including those that belong to the properties of the words themselves and those that relate to the characteristics of the individuals assessing the words. In this study, we present results from a crowdsourced lexical decision megastudy in which more than 150,000 native speakers from around 2...

Assessing the synchrony and interplay between distributed neural regions is critical to understanding how language is processed. Here, we investigated possible neuro-functional links between form and meaning during sentence comprehension combining a classical whole-brain approach, which characterizes patterns of brain activation resulting from our...
Article
Several studies have shown that unbalanced bilinguals activate both of their languages simultaneously during L2 processing; however, evidence for L2 activation while participants are tested exclusively in their L1 has been more tenuous. Here, we investigate whether bilingual participants implicitly activate the label for a picture in their two lang...
Article
Background: Dynamic functional network analysis may add relevant information about the temporal nature of the neurocognitive alterations in PD patients with impulse control disorders (PD-ICD). Our aim was to investigate changes in dynamic functional network connectivity (dFNC) in PD-ICD patients, and topological properties of such networks. Metho...

Spoken words and signs both consist of structured sub-lexical units. While phonemes unfold in time in the case of the spoken signal, visual sub-lexical units such as location and handshape are produced simultaneously in signs. In the current study we investigate the role of sub-lexical units in lexical access in spoken Spanish and in Spanish Sign L...
Poster
The brain mechanisms that support the generalization of semantic representations across different languages remain unclear. Previous studies using multivariate pattern analysis (MVPA) of fMRI signals (Buchweitz et al. 2011; Correia et al. 2014) showed that a classifier trained to decode the meaning of words presented in one language generalized to...

How bilingualism modulates brain areas beyond the language regions is still controversial. Through a comprehensive set of analyses on brain structure, we investigated brain differences between Basque-Spanish bilinguals and monolinguals in children and the elderly, the most sensitive target groups to detect potential brain differences. In particular...
Article
Full-text available
The idea of a bilingual advantage in aspects of cognitive control—including cognitive flexibility, inhibition, working memory, and attention—is disputed. Using a sample of kindergarten children, the present study investigated associations between bilingualism and cognitive flexibility—a relationship that has shown mixed findings in prior literature...
Article
Full-text available
A bilingual advantage in a form of a better performance of bilinguals in tasks tapping into executive function abilities has been reported repeatedly in the literature. However, recent research defends that this advantage does not stem from bilingualism, but from uncontrolled factors or imperfectly matched samples. In this study we explored the pot...
Article
Does the human brain elicit patterns of activity associated with the meaning of words in the absence of conscious awareness? Do such non-conscious semantic representations generalize across languages? This study aimed to address these questions using fMRI-based multivariate pattern analysis (MVPA) in a masked word paradigm. Animal and non-animal wo...
