Bilingualism: Language and Cognition最新文献

We examined how language affects moral judgments in a non-WEIRD population. Tanzanian participants (N = 103) evaluated utilitarian agents in moral dilemmas, either in native Chagga or foreign Swahili. Agents were rated significantly more moral and braver when evaluated in a foreign language. Bravery predicted morality more strongly in the foreign language than in the native language. Indirect sacrifices were judged more moral than direct ones, but equally brave. These findings extend the moral foreign language effect to informally acquired languages and highlight methodological implications for cross-cultural research.

Previous studies revealed structural differences in cerebellar regions between monolinguals and bilinguals. However, the effect of bilingual experiences on cerebellar functional neuroplasticity remains unclear. Using resting-state functional magnetic resonance imaging (fMRI) data, we compared cerebellar functional connectivity (FC) between monolinguals and bilinguals, and then examined how age of second language acquisition (AoA-L2), immersion of L2 (Immersion-L2), proficiency level of L2 (PL-L2) and usage of L2 (Usage-L2) influence cerebellar FC in bilinguals. We found monolinguals exhibited increased FC between lobules VI, VIIIa and superior temporal gyrus. Increased AoA-L2 was related to decreased cerebello-cortical FC involving lobules VI, CrusI and precentral gyrus. Increased Immersion-L2 was associated with decreased cerebello-orbitofrontal FC. Higher PL-L2 corresponded to stronger cerebellar FC with posterior cingulate gyrus. Bilinguals who used L2 more frequently at home exhibited decreased cerebellar FC, while increased social Usage-L2 was associated with increased FC. These findings highlight bilingualism’s impact on cerebellar functional neuroplasticity, shaped by different bilingual experiences.

The present study investigates whether L1 Spanish-L2 English instructed and immersed adult sequential bilinguals show L1 attrition effects in the oral production of subject referring expressions in topic continuity. We tested the predictions from the Pragmatic Principles Violation Hypothesis and controlled for two factors that modulate rates of overproduction, namely antecedent distance and the number of potential antecedents. The results from two oral retelling tasks showed that instructed and immersed bilinguals significantly employ more overt material where functional monolinguals resort to the use of null pronouns. Moreover, factors such as antecedent distance and the number of potential antecedents arguably influence the production of the bilingual groups more strongly. Overall, L1 attrition effects are observed in both L2-immersed and L2-instructed bilinguals. However, attrition effects appear to be milder in instructed bilinguals, who sometimes pattern with functional monolinguals. These results call for new avenues within L1 attrition.

Sound symbolism refers to a non-arbitrary relationship between speech and non-speech sounds and their meaning. We investigated whether bilingual individuals, due to their exposure to diverse linguistic systems, exhibit an advantage in this domain compared to monolinguals, or whether this ability relies on universal mechanisms independent of linguistic background. Ninety-four bilingual (spoken languages: Italian and at least another language; age ranging from 22 to 66 years, M = 35.31, SE = 1.26) and 101 monolingual participants (all Italian speakers; age ranging from 22 to 64 years, M = 36.05, SE = 1.16) were presented with 120 words from four unknown languages and asked to infer their meaning from three alternatives. Results confirmed the presence of sound symbolism, as overall performance was significantly higher than chance, but no significant differences emerged between monolinguals and bilinguals, suggesting that sound symbolism is an automatic cognitive mechanism, independent of prior linguistic experience.
