• Journal of Numerical Cognition

    Welcome to the Journal of Numerical Cognition (JNC). The main objective of this Journal is to provide a scholarly forum for the focused discussion of research into numerical cognition. The Journal aims to be inclusive, and takes numerical cognition to encompass for example all branches of mathematics (including spatial reasoning), and welcomes research for its quality, regardless of whether its origins are in (Cognitive) Psychology, Education, Anthropology, or other disciplines.

    JNC is a free-to-publish, open access and peer-reviewed journal publishing original studies, critical commentaries, theoretical position statements and book reviews relevant to the area. The journal emphasizes scholarship, whilst also seeking to bridge theory and practice. The journal aims to represent the vibrancy and innovation of empirical work and ideas in the field, and showcase the best contemporary research. It seeks to have a worldwide audience, which the open access model facilitates.

    JNC aims to facilitate communication not only amongst psychologists but also between psychologists and cognate disciplines. It also encourages dialogue between theory development and practice with respect to understanding numerical cognition. The objective of the journal is to provide readers with access to high-quality professional information, thus stimulating progress throughout the scientific community. Indeed JNC welcomes contributions from researchers and practitioners irrespective of their geographical location.

  • Personality Science


    Personality Science

    A new online-only, open-access journal
    for scientific inquiries into personality and individual differences

    Free of charge for authors and readers

    Personality psychology is already the psychological discipline with the most bandwidth, examining differences between (interindividual perspective) and within (intraindividual perspective) individuals or groups of individuals in biological, psychological, and social origins, expressions, structures, dynamics, processes, mechanisms, functioning, development, and consequences. The journal Personality Science seeks to capitalize on this rich smorgasbord and subscribes broadly to the idea of even further expanding the field beyond disciplinary or geographic borders. This includes examining non-pathological and pathological individual differences between and within humans, animals, virtual avatars, intelligent systems, and robots. The journal publishes highest-quality theoretical, methodological, empirical, applied, and commentary papers continuously once they are ready – exclusively in an online open-access format (i.e., with no article processing charges or paywalls).

    We plan to foster diversity by three interrelated expansions that set our journal apart from more traditional and narrower top-tier personality journals:

    Expansion of the field. The journal is multidisciplinary in scope and also actively seeks out contributions from fields of science other than psychology (e.g., genetics, anthropology, sociology, computer science, economics, educational science, medicine, political science, etc.) that also study personality and individual differences, broadly construed. It thus seeks to honor personality science as a hub science and enable cross-fertilization of topics, ideas, theories, methods, and applications between different disciplines or areas of inquiry.

    Expansion to the public. The journal welcomes papers that concern how personality science can inform, and be informed by, societal and geo-political issues, public interest, policy, and applied practice. It seeks to open up the field to a more diverse readership, including policy-makers, industry, NGOs, and international institutions. The journal thus aims to publish papers of significant relevance and implications, which includes both basic and applied research.

    Expansions in geographical reach. The journal seeks high-quality publications from authors around the globe and publications using non-WEIRD samples. As geographical diversity is a core concern for us, the journal aims to foster regional diversity and inclusion by a diverse editorial team, special invited topics, and public outreach initiatives.

    Personality Science is an official journal of the European Association of Personality Psychology (EAPP) and published under the PsychOpen GOLD program of the Leibniz Institute for Psychology (ZPID).

    The journal promotes open, transparent, rigorous, and impactful research on personality and individual differences.
    Before submitting your paper, please consult the aims, scope, and values of the journal; its policies; as well as guidelines on Open Science implementations, different paper formats with their requirements, and preparing your submission for Personality Science. Frequently Asked Questions and further information can be found here.

    We are looking forward to your submissions!

  • Sexual Offending: Theory, Research, and Prevention

    The journal “Sexual Offending: Theory, Research, and Prevention (SOTRAP)” is an international peer-reviewed journal open to all scientists, clinicians, and policymakers researching and preventing all forms of sexual violence. We welcome all contributions that enhance or illuminate relevant clinical practice, science, and policy about the etiology, prevention, (risk) assessment, treatment, and management of individuals who have committed sexual offenses or are at risk of doing so. Furthermore, aspects of legal, psychological, and somatic consequences of sexual offending are of interest for the readership of SOTRAP.

    We would like to invite clinicians, practitioners, and academics to submit research articles, reviews, meta-analyses, brief research notes/articles (e.g., brief methodological discussions), and (clinical) case reports/studies. We accept both qualitative and quantitative research. We fully acknowledge the value and importance of open science practices and SOTRAP would like to contribute to a better understanding and implementation of open science practices in the field of sex research and forensic sciences.

    Cover SOTRAP is the official journal of the International Association for the Treatment of Sexual Offenders (IATSO). IATSO was also responsible for the publication of the predecessor of SOTRAP, “Sexual Offender Treatment” (SOT, ISSN 1862-2941).

  • Quantitative and Computational Methods in Behavioral Sciences

    The journal Quantitative and Computational Methods in Behavioral Sciences (QCMB) strives to foster the development of methods in psychology and related fields. To achieve this aim, QCMB publishes scientific articles that are suited to extend the understanding of foundational mathematics used in psychological methods, development of new methods and software or hardware for those, comparison of existing or new methods, and dissemination of this knowledge to a broader audience of scientists in psychology or related fields. QCMB is dedicated to Open Science: All published articles are openly available for free. There is no publication fee for the review process or the publication. QCMB makes all articles available as pre-prints as soon as they go into the review process and keeps them available regardless of the formal decision.

    QCMB publishes articles in two sections:

    The fundamental research section targets an audience of quantitative psychologists, mathematicians, and statisticians with an interest in psychological applications of computational, statistical, and mathematical models. This section publishes articles that advance fundamental research in the field of quantitative psychology. Topics include but are not limited to mathematical foundations of statistical methods, introduction and investigation of heuristics that guide data-analytic decisions, introduction of algorithms, performance analyses of existing software, simulation studies that provide insights into mathematical properties of models, the adoption of statistical learning and machine learning paradigms to psychological inquiries, and mathematical theories related to statistical analyses in quantitative psychology.

    The method dissemination section concentrates on methodological articles that target an audience of social scientists that want to apply top-notch analysis methods. Topics include but are not limited to introducing new statistical methods or software, tutorials explaining the application of statistical methods or software, simulation studies to compare the benefit of methods across different domains, introduction of new data tools used for methodology, and experimental design methods or tools, as for example for optimal study design planning.
