    Qualifying Choice: Ethical Reflection on the Scope of Prenatal Screening.Greg Stapleton - 2017 - Medicine, Health Care and Philosophy 20 (2):195-205.
    In the near future developments in non-invasive prenatal testing may soon provide couples with the opportunity to test for and diagnose a much broader range of heritable and congenital conditions than has previously been possible. Inevitably, this has prompted much ethical debate on the possible implications of NIPT for providing couples with opportunities for reproductive choice by way of routine prenatal screening. In view of the possibility to test for a significantly broader range of genetic conditions with NIPT, the European (...)

    Just Choice: A Danielsian Analysis of the Aims and Scope of Prenatal Screening for Fetal Abnormalities.Greg Stapleton, Wybo Dondorp, Peter Schröder-Bäck & Guido de Wert - 2019 - Medicine, Health Care and Philosophy 22 (4):545-555.
    Developments in Non-Invasive Prenatal Testing and cell-free fetal DNA analysis raise the possibility that antenatal services may soon be able to support couples in non-invasively testing for, and diagnosing, an unprecedented range of genetic disorders and traits coded within their unborn child’s genome. Inevitably, this has prompted debate within the bioethics literature about what screening options should be offered to couples for the purpose of reproductive choice. In relation to this problem, the European Society of Human Genetics and American Society (...)

    What Makes an Effective Representation of Information: A Formal Account of Observational Advantages.Gem Stapleton, Mateja Jamnik & Atsushi Shimojima - 2017 - Journal of Logic, Language and Information 26 (2):143-177.
    In order to effectively communicate information, the choice of representation is important. Ideally, a chosen representation will aid readers in making desired inferences. In this paper, we develop the theory of observation: what it means for one statement to be observable from another. Using observability, we give a formal characterization of the observational advantages of one representation of information over another. By considering observational advantages, people will be able to make better informed choices of representations of information. To demonstrate the (...)

    Evaluating Free Rides and Observational Advantages in Set Visualizations.Andrew Blake, Gem Stapleton, Peter Rodgers & Anestis Touloumis - 2021 - Journal of Logic, Language and Information 30 (3):557-600.
    Free rides and observational advantages occur in visualizations when they reveal facts that must be inferred from an alternative representation. Understanding whether these concepts correspond to cognitive advantages is important: do they facilitate information extraction, saving the ‘deductive cost’ of making inferences? This paper presents the first evaluations of free rides and observational advantages in visualizations of sets compared to text. We found that, for Euler and linear diagrams, free rides and observational advantages yielded significant improvements in task performance. For (...)

    A Capabilities Approach to Prenatal Screening for Fetal Abnormalities.Greg Stapleton, Wybo Dondorp, Peter Schröder-Bäck & Guido de Wert - 2019 - Health Care Analysis 27 (4):309-321.
    International guidelines recommend that prenatal screening for fetal abnormalities should only be offered within a non-directive framework aimed at enabling women in making meaningful reproductive choices. Whilst this position is widely endorsed, developments in cell-free fetal DNA based Non-Invasive Prenatal Testing are now raising questions about its continued suitability for guiding screening policy and practice. This issue is most apparent within debates on the scope of the screening offer. Implied by the aim of enabling meaningful reproductive choices is the idea (...)

    Presence and Absence of Individuals in Diagrammatic Logics: An Empirical Comparison.Gem Stapleton, Andrew Blake, Jim Burton & Anestis Touloumis - 2017 - Studia Logica 105 (4):787-815.
    The development of diagrammatic logics is strongly motivated by the desire to make formal reasoning accessible to broad audiences. One major research problem, for which surprisingly little progress has been made, is to understand how to choose between semantically equivalent diagrams from the perspective of human cognition. The particular focus of this paper is on choosing between diagrams that represent either the presence or absence of individuals. To understand how to best make this choice, we conducted an empirical study. We (...)

    Speedith: A Reasoner for Spider Diagrams.Matej Urbas, Mateja Jamnik & Gem Stapleton - 2015 - Journal of Logic, Language and Information 24 (4):487-540.
    In this paper, we introduce Speedith which is an interactive diagrammatic theorem prover for the well-known language of spider diagrams. Speedith provides a way to input spider diagrams, transform them via the diagrammatic inference rules, and prove diagrammatic theorems. Speedith’s inference rules are sound and complete, extending previous research by including all the classical logic connectives. In addition to being a stand-alone proof system, Speedith is also designed as a program that plugs into existing general purpose theorem provers. This allows (...)
