Policy on prior publication

When authors submit manuscripts to this journal, these manuscripts should not be under consideration, accepted for publication or in press within a different journal, book or similar entity, unless explicit permission or agreement has been sought from all entities involved. However, deposition of a preprint on the author’s personal website, in an institutional repository, or in a preprint archive shall not be viewed as prior or duplicate publication. Authors should follow the Cambridge University Press Preprint Policy regarding preprint archives and maintaining the version of record. 

Article types

The following article types are available for submission at PDA:

Article typeLengthNotes
Research ArticleMax. 18,000 words*Including notes and appendices, but excluding tables and references.
Squib6,000-9,000 wordsIncluding notes and appendices, but excluding tables and references.
Puzzles and Problems6,000-9,000 wordsIncluding notes and appendices, but excluding tables and references.

*PDA explicitly welcomes data-rich submissions. Therefore, exceptions may be made in some cases when overlength is due primarily to the inclusion of data, at the Editors’ discretion.

Please note that submissions that are within the 18,000 word limit but are otherwise lengthy (i.e., over 12,000 words) will be assessed for appropriateness and may be returned for revision before being sent out for review.

PDA’s length policy is in place for multiple reasons, including that it is difficult to provide a timely review for very long submissions as it takes longer to assess them at every stage of the process. After publication, readers may be less inclined to read longer papers than shorter ones, which can reduce the impact of long papers.

Research and reporting requirements


Author statements

All articles submitted to PDA should include the following statements:

  • Acknowledgements (optional) – including a statement disclosing the use of AI during manuscript preparation, if relevant (see the 'Use of artificial intelligence (AI) tools' section below).
  • Authorship contribution statement (CRediT) (optional) – see the 'Authorship and contributorship' section below.
  • Conflict of interest statement (mandatory) – see the ‘Competing interests’ section below.
  • Funding disclosure statement (mandatory)
  • Ethics statement (mandatory) – all papers should be accompanied by a short ethics statement (50-80 words) referring to any external validation of the experiment design, volunteer status of participants, anonymity, competing interests, etc., in accordance with practices in their country and expectations in international academic publishing.
    For more guidance on what information to include within the Ethics statement, see the ‘Ethical approval’ section below. 
  • Data availability statement (mandatory) – see the journal's Research transparency page.

Please read the PDA's research transparency requirements before submitting your manuscript. 

Ethical approval

Research involving human participants, tissue or data should be approved by relevant institutional ethics committee(s) and should conform to international ethical and legal standards for research. The name of the ethics committee that approved the research, the ethics committee approval number and the types of consent obtained should be included at submission, within the paper’s Ethics statement. 

In cases where the need for formal ethics committee approval was waived, the name of the ethics committee that granted the waiver should be included at submission. 

If the article does not require ethical approval, please include the following statement: “Ethical approval was not required.”

Data requirements and referencing

Authors and referees are asked to pay special attention to referencing and to how data is handled in the submission:

  • References should not only include the work consulted, but also the original source if at all possible.
  • Data sources should be clearly referenced and, if publicly available, cited as such (e.g., with a URL), or appended to the article as Supplementary Materials. Where the data is not publicly available, authors should explain why it is not made available in a Data Availability Statement.
  • Generally speaking, the contents and Supplementary Materials for articles reporting results of empirical studies should be sufficient to allow replication by other researchers. For further information, see the 'Supplementary materials' section below.
  • For original data collected in the field, the availability of field notes will clearly depend upon circumstances, but if such notes are available we recommend that they be referenced and made available. Authors reporting original field work should be careful to report the appropriate metadata: where and when data were collected, how it was collected (in detail), and characteristics of those it was collected from including age, education, gender, whether bi- or multilingual, etc., along with a report on the general conditions of the language and community.

Preparing your article for submission


Main document file types

For the initial submission, authors should upload their (anonymized) manuscripts in PDF or MS Word, selecting the file designation 'Main Document' and embedding all figures and tables within the Main Document file. Authors are strongly encouraged to compose their manuscripts in LaTeX, using the style files provided below. A PDF of the LaTeX file should then be generated and submitted via the submission site. If not using LaTeX, authors should use double-spacing throughout. 

Upon acceptance of the manuscript, authors can opt to submit their (de-anonymized) final files in either MS Word or LaTeX. 

  • If using LaTeX, the LaTeX source files, along with individual figure files and a PDF of the final version, will need to be submitted for typesetting purposes.
    You can use the style files available on Overleaf or linked below to prepare your manuscript:
    PDA LaTeX Files

  • If using MS Word, the MS Word manuscript file, along with individual figure files, will need to be submitted for typesetting purposes.
    You can use the MS Word template below to prepare your manuscript:
    PDA MS Word Template


Please note that the final version of the manuscript that has been accepted for publication must adhere to the formatting and style guidelines outlined below.

For more information about how to submit your manuscript directly via Overleaf, please see the further guidance in the 'Overleaf' section below.

Manuscript requirements

All articles submitted to the journal should include:

  • Abstract: Maximum 300 words.
  • Keywords: 3-6 relevant keywords.
  • Word/page count: See full article list above.
  • Cover letter: Making, in brief, the case for your research and why it would be relevant for PDA.

Peer review and anonymization

PDA operates on a double-anonymous peer review policy: authorship of submitted articles must be anonymized. Citations to work conducted by the author(s) need not be anonymized but should be talked about in third person to preserve anonymity. 

Authors must ensure that they cannot be identified from any material submitted for peer review (such as web addresses/pages for raw data, or supplementary files). Please ensure that any material in online repositories is also anonymized (e.g., use anonymized view-only links on OSF and make sure that scripts contain no author-identifying information). 

Inclusive language

PDA supports the LSA’s inclusive language policy, both in general writing style and in choice of examples. Authors may be asked to revise nonconforming manuscripts prior to review.

Referencing system

PDA follows the LSA Unified Referencing Style.

Examples:

Book:

  • In text citations: Akmajian et al. 1985
  • Reference list entry: Akmajian, Adrian, Richard A. Demers & Robert M. Harnish. 1985. Linguistics, 2nd edn. Cambridge, MA: MIT Press.

Book chapter:

  • In-text citation:
  • Reference list entry: Roberts & Holmberg 2005 Roberts, Ian & Anders Holmberg. 2005. On the role of parameters in Universal Grammar: A reply to Newmeyer. In Hans Broekhuis, Norbert Corver, Riny Huybregts, Ursula Kleinhenz & Jan Koster (eds.), Organizing grammar: Linguistic studies in honor of Henk van Riemsdijk, 538-553. Berlin: Mouton de Gruyter.

Journal article:

  • In text citation:
  • Reference list entry: Murray & Vennemann 1983 Murray, Robert W. & Theo Vennemann. 1983. Sound change and syllable structure in Germanic phonology. Language 59(3). 514-528.


Formatting requirements

Author affiliations, where applicable, should adhere to the following conventions:

  • Department/school, university/institution, city, state/province, country (abbreviate USA and UK)
  • Use two-letter postal codes for state/province names
  • If an author has multiple affiliations or if there are multiple authors, use superscript Arabic numerals to differentiate affiliations.

Spelling: either American- or British-English spelling can be used, but either should be used consistently throughout the paper.

Quotes: “double” quotation marks should be used, with periods and commas inside marks and ‘single’ quotation marks for quotes within quotes. Quotes of more than fifty words should be set as extracts with no quotation marks.

Title: the title should be written in sentence case, with subtitle run in and separated from the title by a colon.

Order of parentheses in text: ([])

Commas: the serial comma should be used. 

Abbreviations and acronyms: authors should spell out in full any abbreviations used in their manuscripts the first time that they use it.

Measurements and units: percentages should always be expressed as numerals, even when they are less than 10. However, you should spell out percentages if they begin a sentence. For example: Sales increased 5 percent. Fifty percent of this was due to Aitha. Only use the percent symbol (%) in figures and tables and parentheses.

Numbers: numbers less than 10 should be spelt out. Numerals should be used for numbers of 10 or larger. Exceptions to this rule:

  • Numbers of years are always spelled, as in “two to three years.”
  • Numbers beginning a sentence are always spelled out, as in “Fifteen different models were used…”
  • When a number is spelled out according to one of the rules above and is associated with another number, that second number is also spelled out in order to maintain a consistent appearance. For example, “Fifteen of the twenty-two plans…” instead of “Fifteen of the 22 plans…”.

Punctuation: place punctuation inside the quote if the quote is mid-sentence. For example: “You may confirm this,” said Smith (2008).

Figures and tables: All figures must be called out in the body of the text, in sequential order. All titles and notes to figures and tables must be self-explanatory and sourced (with full references provided as outlined above). 

  • Figures may have sources, and tables must have sources.
  • Table column and row headings should be written in sentence case.

For more information on how to submit figures and artwork, visit the Cambridge's Journals Artwork Guide.

Note: If your article contains any material in which you do not own copyright, including figures, charts, tables, photographs or excerpts of text, you must obtain permission from the copyright holder to reuse that material. For more details, see the Cambridge's Guidance on seeking permission to use copyrighted material.

Overleaf

Overleaf is a free online tool for writing and submitting scholarly manuscripts. An Overleaf template is available for this journal, which allows authors to easily comply with the journal’s guidelines.

Benefits of using Overleaf include:

  • An intuitive interface, in which authors can write in LaTeX or rich text and see a preview of their article typeset in the journal’s style
  • Features enabling collaboration with co-authors (the ability to share, highlight and comment on versions of articles)
  • Sophisticated version control
  • Clean PDF conversion and submission into the journal’s online manuscripts system (supporting materials can also be added during this process)

Overleaf is based on LaTeX but includes a rich text mode. An author writing in Overleaf would need to have some knowledge of LaTeX, but could collaborate through the tool with an author who is not a LaTeX expert. Overleaf’s tutorial pages include a two minute video and an introduction to LaTeX course, and Overleaf also provides support for authors using the tool.

Note: authors should flatten their image files before uploading them to Overleaf and the journal’s submission system. This can be done by using Photoshop or GIMP, an open source Photoshop equivalent, both of which have a ‘Flatten Image’ option in the Layer menu. If you are using a locally installed LaTeX editor, it’s also possible to use in-line commands to do a round-trip conversion – see this Overleaf help page for more information.

You can access the PDA Overleaf template directly on Overleaf. There is a direct link to submit your manuscript from within the Overleaf authoring environment. Once you have completed writing your article, please use the "Submit to Journal" button and select the link for PDA to be directed to the journal's submission system.

Competing Interests

All authors must include a competing interest declaration in their title page. This declaration will be subject to editorial review and may be published in the article.

Competing interests are situations that could be perceived to exert an undue influence on the content or publication of an author’s work. They may include, but are not limited to, financial, professional, contractual or personal relationships or situations.

If the manuscript has multiple authors, the author submitting must include competing interest declarations relevant to all contributing authors. 

Example wording for a declaration is as follows: “Competing interests: Author 1 is employed at organisation A, Author 2 is on the Board of company B and is a member of organisation C. Author 3 has received grants from company D.” If no competing interests exist, the declaration should state “Competing interests: The author(s) declare none”. 

Author affiliations

Author affiliations should represent the institution(s) at which the research presented was conducted and/or supported and/or approved. For non-research content, any affiliations should represent the institution(s) with which each author is currently affiliated. 

For more information, please see our author affiliation policy and author affiliation FAQs.

Authorship and contributorship

All authors listed on any papers submitted to this journal must be in agreement that the authors listed would all be considered authors according to disciplinary norms, and that no authors who would reasonably be considered an author have been excluded. For further details on this journal’s authorship policy, please see this journal's publishing ethics policies.

CRediT taxonomy for contributors

When submitting a manuscript, the corresponding author will be prompted to provide further details concerning contributions to the manuscript using the CRediT taxonomy. CRediT (Contributor Roles Taxonomy) is a high-level taxonomy, including 14 designated options, that can be used to represent the roles typically played by contributors to scholarly output. All parties who have contributed to the scholarly work, but do not meet the full criteria for authorship, should be recognised with their contributions described in terms of the CRediT taxonomy.

Our default position is that the corresponding author has the authority to act on behalf of all co-authors, and we expect the corresponding author to confirm this at the beginning of the submission process. When preparing your manuscript you should also ensure that you obtain permission from all contributors to describe their contributions using the CRediT taxonomy.

Use of artificial intelligence (AI) tools

We acknowledge the increasing use of artificial intelligence (AI) tools in the research and writing processes. To ensure transparency, we expect any such use to be declared and described fully to readers, and to comply with our plagiarism policy and best practices regarding citation and acknowledgements. We do not consider artificial intelligence (AI) tools to meet the accountability requirements of authorship, and therefore generative AI tools such as ChatGPT and similar should not be listed as an author on any submitted content. 

In particular, any use of an AI tool: 

  • to generate images within the manuscript should be accompanied by a full description of the process used, and declared clearly in the image caption(s) 
  • to generate text within the manuscript should be accompanied by a full description of the process used, include appropriate and valid references and citations, and be declared in the manuscript’s Acknowledgements. 
  • to analyse or extract insights from data or other materials, for example through the use of text and data mining, should be accompanied by a full description of the process used, including details and appropriate citation of any dataset(s) or other material analysed in all relevant and appropriate areas of the manuscript 
  • must not present ideas, words, data, or other material produced by third parties without appropriate acknowledgement or permission 

Descriptions of AI processes used should include at minimum the version of the tool/algorithm used, where it can be accessed, any proprietary information relevant to the use of the tool/algorithm, any modifications of the tool made by the researchers (such as the addition of data to a tool’s public corpus), and the date(s) it was used for the purpose(s) described. Any relevant competing interests or potential bias arising as a consequence of the tool/algorithm’s use should be transparently declared and may be discussed in the article. 

ORCID

We require all corresponding authors to identify themselves using ORCID when submitting a manuscript to this journal. ORCID provides a unique identifier for researchers and, through integration with key research workflows such as manuscript submission and grant applications, provides the following benefits:

  • Discoverability: ORCID increases the discoverability of your publications, by enabling smarter publisher systems and by helping readers to reliably find work that you have authored.
  • Convenience: As more organisations use ORCID, providing your iD or using it to register for services will automatically link activities to your ORCID record, and will enable you to share this information with other systems and platforms you use, saving you re-keying information multiple times.
  • Keeping track: Your ORCID record is a neat place to store and (if you choose) share validated information about your research activities and affiliations.

See our ORCID FAQs for more information.

If you don’t already have an iD, you will need to create one if you decide to submit a manuscript to this journal. You can register for one directly from your user account on ScholarOne, or alternatively via https://ORCID.org/register.

If you already have an iD, please use this when submitting your manuscript, either by linking it to your ScholarOne account, or by supplying it during submission using the "Associate your existing ORCID iD" button.

ORCIDs can also be used if authors wish to communicate to readers up-to-date information about how they wish to be addressed or referred to (for example, they wish to include pronouns, additional titles, honorifics, name variations, etc.) alongside their published articles. We encourage authors to make use of the ORCID profile’s “Published Name” field for this purpose. This is entirely optional for authors who wish to communicate such information in connection with their article. Please note that this method is not currently recommended for author name changes: see Cambridge’s author name change policy if you want to change your name on an already published article. See our ORCID FAQs for more information. 

Supplementary materials

Material that is not essential to understanding or supporting a manuscript, but which may nonetheless be relevant or interesting to readers, may be submitted as supplementary materials. Supplementary materials will be published online alongside your article, but will not be published in the pages of the journal. Types of supplementary materials may include, but are not limited to, appendices, additional tables or figures, datasets, videos, and sound files.

Supplementary materials will be published with the same metadata as your parent article, and are considered a formal part of the academic record, so cannot be retracted or modified other than via our article correction processes. Supplementary materials will not be typeset or copyedited, so should be supplied exactly as they are to appear online. Please make sure you are familiar with our detailed guidance on supplementary materials prior to submission.

Where relevant we encourage authors to publish additional qualitative or quantitative research outputs in an appropriate repository, and cite these in manuscripts.
