Focus and Scope

Theoria et Historia Scientiarum (THS) is an international academic journal, published annually by the Nicolaus Copernicus University since 1991. Its first editor in chief, Tomasz Komendziński, now shares this function with Sławomir Wacewicz and Przemysław Żywiczyński. The journal’s editorial board includes some of the world’s leading scholars in Cognitive Science and language evolution.

More recently, the thematic scope of the journal has been Cognitive Science, broadly construed. Since 2012, the journal has been co-edited by the Center for Language Evolution Studies at Nicolaus Copernicus University in Torun, and language evolution – field of interdisciplinary research into the evolutionary origins of the human language faculty – has been a domain of particular interest.

THS is an international journal, with a great majority of authors representing research centres located in the US and Western Europe. We have had many contributions from authors affiliated with Polish institutions, as well as some from other countries, such as Japan, Romania, Russia or Thailand.

Peer Review Process

All submitted manuscripts have to fall within the aims and thematic scope of the journal, i.e. Cognitive Science / language origins, very broadly construed, and meet the requirements described in the guidelines section. Note that if a manuscript does not meet the above criteria or contains glaring language or content errors, it will not be considered for peer review.

THS uses single-blind peer review: reviewers are aware of the identity of the authors, but authors are unaware of the identity of reviewers. Manuscripts are reviewed by scholars who are independent specialists within the particular scientific fields. There are at least three or more reviewers for the total number of articles in each issue.

Normal standards of academic quality apply, including originality/novelty, cogency of the argument, accuracy of the review, or methodological correctness. Based on the opinions of the reviewers, the editors take the final decision to reject the paper, accept with minor or major revisions, or accept as is. The author is notified of the decision via the OJS system.
