    Noun-phrase production as a window to language selection: an ERP study

    Get PDF
    Characterising the time course of non-native language production is critical in understanding the mechanisms behind successful communication. Yet, little is known about the modulating role of cross-linguistic influence (CLI) on the temporal unfolding of non-native production and the locus of target language selection. In this study, we explored CLI effects on non-native noun phrase production with behavioural and neural methods. We were particularly interested in the modulation of the P300 as an index for inhibitory control, and the N400 as an index for co-activation and CLI. German late learners of Spanish overtly named pictures while their EEG was monitored. Our results indicate traceable CLI effects at the behavioural and neural level in both early and late production stages. This suggests that speakers faced competition between the target and non-target language until advanced production stages. Our findings add important behavioural and neural evidence to the underpinnings of non-native production processes, in particular for late learners.Horizon 2020(H2020)Theoretical and Experimental Linguistic

    Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

    PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

    Switching direction modulates the engagement of cognitive control in bilingual reading comprehension: An ERP study

    No full text
    Abstract: While switching costs in production have been explained in terms of top-down cognitive control, researchers do not agree whether switching costs in comprehension should be interpreted in the same way. Within the BIA + model, it has been claimed that the comprehension of code-switches can be explained sufficiently in terms of bottom-up activation of lexical representations. In the current electrophysiological study, L1 speakers of Dutch with high proficiency in L2 English (n = 63) completed a Flanker task in which they intermittently read sentences with or without an alternational code-switch. With this ‘conflict-adaptation’ paradigm we examined whether reading a code-switch engages cognitive control that influences performance on a subsequent Flanker trial. Half of the participants were presented with Dutch sentences and Dutch to English code-switches, while the other half were presented with English sentences and English to Dutch code-switches. On the P300 component, we found a traditional Flanker effect, with larger amplitudes for congruent than for incongruent trials. The effect was modulated by a preceding code-switch and the direction of this modulation depended on the switching direction: the Flanker effect was smaller after a code-switch from L1 to L2 than after a monolingual L1 sentence, but larger after a code-switch from L2 to L1 than after a monolingual L2 sentence. This suggests that the L1 needs to be inhibited when reading a code-switch to the L2, while inhibition needs to be released upon encountering a code-switch from L2 to L1. These results thus show that reading code-switched sentences engages a domain-general cognitive control mechanism external to the lexicon.Theoretical and Experimental Linguistic
