General Information
(manuscript style is found below)

Cognitive Research: Principles and Implications (CR:PI) is an Open Access journal that publishes new empirical and theoretical work covering all areas of Cognition, with a special emphasis on use-inspired basic research: fundamental and theoretically relevant research that grows from hypotheses about real-world problems. For any submission, we expect that authors will be able to explain in a Significance section how their basic research serves to advance our understanding of the cognitive aspects of a problem with real-world applications. There are five types of submissions:

  1. Research Articles: These articles typically describe several experiments unified by an introduction and a closing discussion placing the experiments in the context of other work in the field and providing a coherent theoretical account of the new knowledge found in the results of those experiments. While the majority of published articles are reports of experimental investigations in these content areas, articles that are primarily theoretical or integrative are also welcome. There are no explicit length restrictions, but an acceptable article must make a substantial contribution to the field.
  2. Brief Reports: This format is intended to facilitate the rapid publication of breaking news of general interest to the CR:PI community.Brief reports are limited to 3,000 words of main body text plus figures. A cover letter to the Editor should explain why this is appropriate as a Brief Report. A brief report need not, and probably should not be limited to a single experiment. Even in a brief report, we seek clear evidence that results are replicable; the most obvious evidence being replication and extension of the result in more than one experiment, reported in the manuscript.
  3. Registered Reports or Replications (RRR): This format is another effort intended to strengthen the reliability and validity of the results in our science. RRR submission is a two-stage process. Authors submit a proposed study. If it passes initial review, CR:PI will commit to publishing the results, regardless of the outcome, assuming that the methods and analysis in the final study conforms to the initially approved proposal.

The Registered Report format is appropriate for two types of studies:

  1. Direct, precise replications of studies that are worth replicating (i.e. the original finding is of clear significance). Replications of one’s own work would not be appropriate for this format.
  2. Studies that seek to test clearly articulated, theoretically significant hypotheses (e.g., Theory A predicts X whereas Theory B predicts Y) where the answer is of interest, regardless of the outcome.

The initial submission of a RRR should include the following items:

  1. A cover letter to the Editor explaining why the submission is appropriate as a Registered Report or Replication.
  2. The background section should describe the theory under investigation and the specific hypotheses that lead to the procedures proposed. RRR submissions are not the place for methodological and/or theoretical innovations: Our standard Article and Short Report formats serve those roles. The RRR format is a mechanism for confirming or disconfirming prominent theories and findings in the field.
  3. The background section should briefly report any previous, related experiments, published or unpublished, conducted by the authors (in addition to the usual background of prior work).
  4. The proposed method section must specify all of the variables, both independent and dependent, in the experiment.
  5. The proposed method section must address the issue of statistical power although we recognize that classic power analysis may not be appropriate for all designs. Please convince us that you are collecting an adequate amount of data.
  6. The proposed method section must specify a clear rule for terminating data collection (number of observers, number of trials, etc.).
  7. The proposed method section must specify the data analysis procedures that will be used, including rules for data elimination.
  8. There must be a plan for making the raw data publicly available.
  9. The cover letter must attest that the preceding points have been attended to and that the project has ethics approval and all other necessary approvals & that funding is in place to start the research immediately on approval.

The final submission of an RRR manuscript should include the following items:

  1. The cover letter must certify that the data for the registered experiment were collected after receiving approval from CR:PI.
  2. The completed experiment(s) must have been executed and analyzed in the manner originally approved with any unforeseen changes in those approved methods and analyses clearly noted.
  3. The manuscript must describe and justify all post-hoc analyses.
  4. While CR:PI will commit to publishing the results, review of the final submission may lead to comments that need to be addressed in revision. CR:PI’s commitment is to the results, not to the discussion section.

Once a RRR is approved, the authors have one year to submit the actual manuscript with the results. That deadline can be extended by negotiation with the Editor but, in general, the project requires new approval one year after its initial acceptance.

Registered reports are limited to 3,000 words of main body text plus figures, although exceptions are possible if approved by the Editor; supplementary material is encouraged.

More details about RRR submissions can be found in a published editorial in our sister Psychonomic Society journal, Attention, Perception, and Psychophysics. Wolfe, J. M. (2013). Registered Reports and Replications in Attention, Perception, & Psychophysics. Attention, Perception, & Psychophysics, 75(5), 781-783.

  1. Tutorial Reviews:Tutorial Reviews are intended to serve as high-level introductory reviews of relatively broad topics in the domain of the journal. Length is “moderate” (i.e. shorter than Annual Review chapters, longer than Current Directions in Psychological Science articles). Bibliography should be extensive. Please note: Tutorial reviews are often commissioned by invitation but self-nominations are welcome. Send a brief email describing the proposed review and providing a bare outline to the Editor in Chief or any Associate Editor.
  2. Research Highlights: CR:PI seeks very brief (1-2 paragraph) accounts of current articles in the journal and elsewhere. These are news reports similar to the “Research Highlights” section of Nature. These are NOT submitted through the manuscript submission website. These will typically appear on the Psychonomic Society website. If you think that the CR:PI community should be made aware of an article (presumably, not one of your own), feel free to submit 2-3 brief paragraphs to any editor.

Manuscript Style

Manuscripts are to adhere to the conventions described in the Publication Manual of the American Psychological Association (6th ed.), except for the locations of Figures, Tables and Footnote (see below). See for information on APA style, or type “APA style” into a search engine to find numerous online sources of information about APA style. Here we highlight only the most fundamental aspects of that style.

All manuscripts are to be double spaced and have 1-inch margins with page numbers in the upper right corner of each page.

Title Page
The title page must include the authors’ names and affiliations and the corresponding author’s address, telephone number, and e-mail address.
There must be an abstract of no more than 250 words.  

IMPORTANT: There must be a Significance Statement, also of no more than 250 words. Recall that CR:PI is focused on “use-inspired basic research”, fundamental research that grows from hypotheses about real-world problems. The significance statement should make clear how your work was derived from an issue in the world. Ideally, the significance statement should be understandable by a broad audience and not only be specialists in our field. If you have questions about this aspect of your manuscript, send  an e-mail to the Editor in Chief, Jeremy Wolfe.

Manuscript should be divided into sections (and perhaps subsections) appropriate for their content (e.g., introduction/background, Method, Results, etc.), as per APA style.
The Author Note should include sources of financial support and any possible conflicts of interest. If desirable, contributions of different authors may be briefly described here. Reviewers and the Editor should not be thanked in the Author Note.

Figures and Tables

Figures and tables are to be designed as per APA style.

Location of Figures, Tables, and Footnotes
In submitted manuscripts, please embed figures and tables in the body of the text as this is easier for on-screen reading. Footnotes can be placed at the bottom of the page on which the footnoted material is referenced. Note that this is a departure from APA style. In addition, it can be useful to add a second copy of the figures, tables, and footnotes at the end. When a paper is accepted, in the final version that the author submits for production each figure and table must be on a separate page near the end of the manuscript and all footnotes must be listed on a footnote page, as per the APA Publication Manual.

Citations and References

These should conform to APA style.

Cover Letter
Authors are encouraged to provide a cover letter with newly submitted manuscripts. It should very briefly describe the main findings and conclusions of the paper. It is helpful to offer suggestions about appropriate reviewers. However, the final selection of reviewers lies with the editors.
