We invite submissions of papers and posters that shed light on various aspects of the overarching theme, which emphasizes multilingualism as a dynamic and multi-layered phenomenon that must be studied across various levels of analysis. In addition to submissions that look at the effects of multilingualism within the individual domains of Language, Brain and Learning, we especially welcome submissions that go beyond single-domain perspectives to address how linguistic representations, neurocognitive mechanisms, and learning environments interact. We encourage research that aligns with cross-cutting themes such as the interaction of multiple linguistic systems, the role of linguistic and typological distance, the neurocognitive dynamics of language learning, individual variation in multilingual development, and the relationship between multilingualism and literacy. Submissions may highlight, but need not be limited to, the effects of multilingualism relative to any of the topics on the following non-exhaustive list:

  • Code-switching
  • Cognitive aging
  • Cognitive control
  • Cross-cultural perspectives
  • Cross-linguistic comparisons
  • Cross-linguistic influence 
  • Executive functions
  • Heritage languages
  • Immersion and exposure
  • Indigenous languages
  • Language acquisition (L1 — including bilingual and trilingual L1 — , L2 and L3/Ln)
  • Language attrition
  • Language disorders
  • Language learning
  • Language learning environments
  • Language learning pedagogies
