Despite the multifactorial space of language experience in which people continuously vary, bilinguals are often dichotomized into ostensibly homogeneous groups. The timing of language exposure (age of acquisition) to a second language (L2) is one well-studied construct that is known to impact language processing, cognitive processing, and brain organization, but recent work shows that current language exposure is also a crucial determinant in these domains. Critically, many indices of bilingual experience are inherently subjective and based on self-report questionnaires. Such measures have been criticized in favor of objective measures of language ability (e.g., naming ability or verbal fluency). Here, we estimate the bilingual experience jointly as a function of multiple continuous aspects of experience, including the timing of language exposure, the amount of L2 exposure across communicative contexts, and language entropy (a flexible measure of language balance) across communicative contexts. The results suggest that current language exposure exhibits distinct but interrelated patterns depending on the socio-experiential context of language usage. They also suggest that, counterintuitively, our sample more accurately self-assesses L2 proficiency than native language proficiency. A precise quantification of the multidimensional nature of bilingualism will enhance the ability of future research to assess language processing, acquisition, and control.

A proliferation of popular music genres flourished in post-independence Nigeria: highlife, jùjú, Afrobeat, and fújì. Originating within Yorùbá Muslim communities, the genres of fújì and Islamic are Islamised dance music genres characterised by their Arabic-influenced vocal style, Yorùbá praise poetry, driving percussion, and aesthetics of incorporation, flexibility, and cultural fusion. Based on analysis of interviews and performances in Ìlọrin in the 2010s, this article argues that the genres of fújì and Islamic allegorise Nigerian unity—an ideology of tolerance, peaceful coexistence, and equity—while exposing the gap between the aspiration for unity and everyday inequities shaped by gender and morality.

Although bilinguals benefit from semantic context while perceiving speech-in-noise in their native language (L1), the extent to which bilinguals benefit from semantic context in their second language (L2) is unclear. Here, 57 highly proficient English–French/French–English bilinguals, who varied in L2 age of acquisition, performed a speech-perception-in-noise task in both languages while event-related brain potentials were recorded. Participants listened to and repeated the final word of sentences high or low in semantic constraint, in quiet and with a multi-talker babble mask. Overall, our findings indicate that bilinguals do benefit from semantic context while perceiving speech-in-noise in both their languages. Simultaneous bilinguals showed evidence of processing semantic context similarly to monolinguals. Early sequential bilinguals recruited additional neural resources, suggesting more effective use of semantic context in L2, compared to late bilinguals. Semantic context use was not associated with bilingual language experience or working memory.

The most recent generational shift in the culture of Yorùbá Bàtá performance has provoked frustration in older artists who are worried that their tradition is dying. The generation of artists in its twenties fuses traditional bàtá, with popular musical genres, creating a fusion style I call “pop tradition.” “Pop” signifies the young artists' desires to identify with a pan-Yorùbá and global culture, fueling a particular worldly performance style rooted in both tradition and modernity.
