About this Research Topic

Background

This Research Topic focuses on heritage languages at the crossroads by approaching heritage language bilingualism in an interdisciplinary way. A language qualifies as a heritage language if it is a minority language spoken at home in a majority language context. Any language can be the societal majority language in one context and the heritage language in another. While the number of empirical studies on language acquisition and processing in heritage language bilingualism has increased in recent years, heritage language bilinguals are an understudied subgroup of bilinguals. When examined as adults, heritage-speaker bilinguals tend to show significant differences in their heritage language performance (use) and competence (grammatical knowledge) from one another. This variation is particularly unusual because heritage speakers, like monolinguals, are native speakers of the heritage language.

Heritage language speakers exhibit a level of variation in both their language use and grammatical knowledge that is not typically observed in monolinguals. Although this variation is evident, research is focused on when and why heritage speakers diverge from monolinguals and from one another, as well as determining which methodologies can best account for this variation. Despite recent progress in heritage language research, studies that consider the role of varying cultural contexts on individual differences and draw on different disciplines to interpret these findings are strongly needed. This Research Topic aims to advance heritage language research by bringing together diverse perspectives and promoting the use of advanced methodologies. Ultimately, the Topic will offer a comprehensive and current overview of the field, outlining its accomplishments, challenges, and future directions.

This Research Topic welcomes submissions on heritage language bilingualism in any and all contexts globally, including returnees. The Topic aims to bring together contributions investigating heritage language bilingualism from various disciplines, including (applied, psycho-, neuro-) linguistics, cognitive science, neuroscience, deaf/hearing impaired studies, language policy, ethnolinguistic studies, language pedagogy, and other related fields. Empirical work on language acquisition, linguistic processing, attrition, linguistic and (related) cognitive development, motivation, identity, equality, education, and policy as well as theoretical and methodological epistemology are welcome. This includes all domains of language (e.g., syntax, morphology, semantics, phonology, the lexicon and discourse/pragmatics, and their interfaces) and any and all appropriate methodologies, online and offline experimental or other methods (e.g., corpora).

We particularly welcome the following topics (but are not limited to):

• linguistic properties of heritage languages in children and adults
• heritage language acquisition and development
• the role of extra-linguistic variables in heritage language acquisition/maintenance
• crosslinguistic influence in heritage language speech production and comprehension
• code-switching/translanguaging in heritage speakers
• neurocognitive adaptations within heritage bi-/multilingualism
• first language / cross-generational attrition
• heritage language instruction
• multimodal language and communication
• research investigating so-called “returnee” contexts
• methods in heritage language bilingualism
• empirical and/or epistemological work on motivation, identity, and equality in Heritage Language Research.

Keywords: heritage language, bilingualism, language acquisition, language processing, cognitive development, language policy, language pedagogy

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).
