    Hypatia's Silence. Truth, Justification, and Entitlement.Martin Fischer, Leon Horsten & Carlo Nicolai - manuscript
    Hartry Field distinguished two concepts of type-free truth: scientific truth and disquotational truth. We argue that scientific type-free truth cannot do justificatory work in the foundations of mathematics. We also present an argument, based on Crispin Wright's theory of cognitive projects and entitlement, that disquotational truth can do justificatory work in the foundations of mathematics. The price to pay for this is that the concept of disquotational truth requires non-classical logical treatment.

    Axiomatizing Semantic Theories of Truth?Martin Fischer, Volker Halbach, Jönne Kriener & Johannes Stern - 2015 - Review of Symbolic Logic 8 (2):257-278.
    We discuss the interplay between the axiomatic and the semantic approach to truth. Often, semantic constructions have guided the development of axiomatic theories and certain axiomatic theories have been claimed to capture a semantic construction. We ask under which conditions an axiomatic theory captures a semantic construction. After discussing some potential criteria, we focus on the criterion of ℕ-categoricity and discuss its usefulness and limits.

    Heuristics and Biases in Mental Arithmetic: Revisiting and Reversing Operational Momentum.Samuel Shaki, Michal Pinhas & Martin H. Fischer - 2018 - Thinking and Reasoning 24 (2):138-156.
    Mental arithmetic is characterised by a tendency to overestimate addition and to underestimate subtraction results: the operational momentum effect. Here, motivated by contentious explanations of this effect, we developed and tested an arithmetic heuristics and biases model that predicts reverse OM due to cognitive anchoring effects. Participants produced bi-directional lines with lengths corresponding to the results of arithmetic problems. In two experiments, we found regular OM with zero problems but reverse OM with non-zero problems. In a third experiment, we tested (...)

    TEST: A Tropic, Embodied, and Situated Theory of Cognition.Andriy Myachykov, Christoph Scheepers, Martin H. Fischer & Klaus Kessler - 2014 - Topics in Cognitive Science 6 (3):442-460.
    TEST is a novel taxonomy of knowledge representations based on three distinct hierarchically organized representational features: Tropism, Embodiment, and Situatedness. Tropic representational features reflect constraints of the physical world on the agent's ability to form, reactivate, and enrich embodied (i.e., resulting from the agent's bodily constraints) conceptual representations embedded in situated contexts. The proposed hierarchy entails that representations can, in principle, have tropic features without necessarily having situated and/or embodied features. On the other hand, representations that are situated and/or embodied (...)

    Reading Space Into Numbers: A Cross-Linguistic Comparison of the SNARC Effect.Samuel Shaki & Martin H. Fischer - 2008 - Cognition 108 (2):590-599.
    Small numbers are spontaneously associated with left space and larger numbers with right space (the SNARC effect), for example when classifying numbers by parity. This effect is often attributed to reading habits but a causal link has so far never been documented. We report that bilingual Russian-Hebrew readers show a SNARC effect after reading Cyrillic script (from left-to-right) that is significantly reduced after reading Hebrew script (from right-to-left). In contrast, they have similar SNARC effects after listening to texts in either (...)

    Minimal Truth and Interpretability.Martin Fischer - 2009 - Review of Symbolic Logic 2 (4):799-815.
    In this paper we will investigate different axiomatic theories of truth that are minimal in some sense. One criterion for minimality will be conservativity over Peano Arithmetic. We will then give a more fine-grained characterization by investigating some interpretability relations. We will show that disquotational theories of truth, as well as compositional theories of truth with restricted induction are relatively interpretable in Peano Arithmetic. Furthermore, we will give an example of a theory of truth that is a conservative extension of (...)

    Truth and Speed-Up.Martin Fischer - 2014 - Review of Symbolic Logic 7 (2):319-340.
    In this paper, we investigate the phenomenon of speed-up in the context of theories of truth. We focus on axiomatic theories of truth extending Peano arithmetic. We are particularly interested on whether conservative extensions of PA have speed-up and on how this relates to a deflationist account. We show that disquotational theories have no significant speed-up, in contrast to some compositional theories, and we briefly assess the philosophical implications of these results.

    Some Remarks on Restricting the Knowability Principle.Martin Fischer - 2013 - Synthese 190 (1):63-88.
    The Fitch paradox poses a serious challenge for anti-realism. This paper investigates the option for an anti-realist to answer the challenge by restricting the knowability principle. Based on a critical discussion of Dummett's and Tennant's suggestions for a restriction desiderata for a principled solution are developed. In the second part of the paper a different restriction is proposed. The proposal uses the notion of uniform formulas and diagnoses the problem arising in the case of Moore sentences in the different status (...)

    Singing Numbers… in Cognitive Space — A Dual‐Task Study of the Link Between Pitch, Space, and Numbers.Martin H. Fischer, Marianna Riello, Bruno L. Giordano & Elena Rusconi - 2013 - Topics in Cognitive Science 5 (2):354-366.
    We assessed the automaticity of spatial-numerical and spatial-musical associations by testing their intentionality and load sensitivity in a dual-task paradigm. In separate sessions, 16 healthy adults performed magnitude and pitch comparisons on sung numbers with variable pitch. Stimuli and response alternatives were identical, but the relevant stimulus attribute (pitch or number) differed between tasks. Concomitant tasks required retention of either color or location information. Results show that spatial associations of both magnitude and pitch are load sensitive and that the spatial (...)

    Paradoxes of Interaction?Johannes Stern & Martin Fischer - 2015 - Journal of Philosophical Logic 44 (3):287-308.
    Since Montague’s work it is well known that treating a single modality as a predicate may lead to paradox. In their paper “No Future”, Horsten and Leitgeb show that if the two temporal modalities are treated as predicates paradox might arise as well. In our paper we investigate whether paradoxes of multiple modalities, such as the No Future paradox, are genuinely new paradoxes or whether they “reduce” to the paradoxes of single modalities. In order to address this question we develop (...)

    Moving Arms: The Effects of Sensorimotor Information on the Problem-Solving Process.Karsten Werner, Markus Raab & Martin H. Fischer - forthcoming - Thinking and Reasoning:1-21.
    Embodied cognition postulates a bi-directional link between the human body and its cognitive functions. Whether this holds for higher cognitive functions such as problem solving is unknown. We predicted that arm movement manipulations performed by the participants could affect the problem-solving solutions. We tested this prediction in quantitative reasoning tasks that allowed two solutions to each problem. In two studies with healthy adults, we found an effect of problem-congruent movements on problem solutions. Consistent with embodied cognition, sensorimotor information gained via (...)

    Truth, Partial Logic and Infinitary Proof Systems.Martin Fischer & Norbert Gratzl - 2018 - Studia Logica 106 (3):515-540.
    In this paper we apply proof theoretic methods used for classical systems in order to obtain upper bounds for systems in partial logic. We focus on a truth predicate interpreted in a Kripke style way via strong Kleene; whereas the aim is to connect harmoniously the partial version of Kripke–Feferman with its intended semantics. The method we apply is based on infinitary proof systems containing an ω-rule.

    Service-Robotic—mainly defined as “non-industrial robotics”—is identified as the next economical success story to be expected after robots have been ubiquitously implemented into industrial production lines. Under the heading of service-robotic, we found a widespread area of applications reaching from robotics in agriculture and in the public transportation system to service robots applied in private homes. We propose for our interdisciplinary perspective of technology assessment to take the human user/worker as common focus. In some cases, the user/worker is the effective subject (...)

    Non-Abstractness as Mental Simulation in the Representation of Number.Andriy Myachykov, Wouter Platenburg & Martin H. Fischer - 2009 - Behavioral and Brain Sciences 32 (3-4):343 - 344.
    ion is instrumental for our understanding of how numbers are cognitively represented. We propose that the notion of abstraction becomes testable from within the framework of simulated cognition. We describe mental simulation as embodied, grounded, and situated cognition, and report evidence for number representation at each of these levels of abstraction.

    Constructional Morphology: The Analysis of Constraints in Evolution Dedicated to A. Seilacher in Honour of His 60. Birthday.Wolf-Ernst Reify, Roger D. K. Thomas & Martin S. Fischer - 1985 - Acta Biotheoretica 34 (2-4):233-248.
    Evolutionary change is opportunistic, but its course is strongly constrained in several fundamental ways. These constraints (historical/phylogenetic, functional/adaptive, constructional/morphogenetic) and their dynamic relationships are discussed here and shown to constitute the conceptual framework of Constructional Morphology. Notwithstanding recent published opinions which claim that the discovery of constraints renders Neodarwinian selection theory obsolete, we regard the insights of Constructional Morphology as being entirely consistent with this theory. As is shown here in the case of the Hyracoidea, formal analysis of the constraints (...)

    The Design of Technical Artifacts with Regard to Work Experience: The Development of an Experience-Based Documentation System for Maintenance Workers. [REVIEW]Martin Fischer, Eberhard Römmermann & Heinrich Benckert - 1996 - AI and Society 10 (1):39-50.
    The German discussion about experience-guided work has led to the question of how work experience can be regarded within the process of designing technical artifacts. This paper offers a solution for the area of skilled maintenance work. Some considerations about the nature of experience and about the problems skilled workers have in aquiring work competences within computer aided production environments are introduced in order to illustrate the design philosophy: A decision-support-system is described which stimulates workplace learning by enabling previous and (...)

    Recent findings suggest that medical students’ moral competence decreases throughout medical school. This pilot study gives preliminary insights into the effects of two educational interventions in ethics classes on moral competence among medical students in Munich, Germany. Between 2012 and 2013, medical students were tested using Lind’s Moral Competence Test prior to and after completing different ethics classes. The experimental group participated in principle-based structured case discussions and was compared with a control group with theory-based case discussions. The pre/post C-scores (...)

    Formative Evaluation of the CASUS Authoring System for Problem-Based Learning.Martin Fischer, Cornelia Gräsel, Sepp Bruckmoser, Jana Konschak, Thomas Baehring, Heinz Mandl & Peter Christian Scriba - unknown
    CASUS is an authoring system, which should enable physicians to produce problem-based computer learning programs with minimal technical effort and give them sound instructional support. The theoretical background of CASUS are constructivist approaches to learning and instruction, which deal mainly with the question, how to design problem-based learning environments. The paper presents the constructivist concept of CASUS and results of a forma-tive evaluation. Four authors were observed and interviewed while developing a learning case with CASUS.

    What are the underlying processes that enable human beings to recognize a happy face? Clearly, featural and configural cues will help to identify the distinctive smile. In addition, the motivational state of the observer will influence the interpretation of emotional expressions. Therefore, a model accounting for emotion recognition is only complete if bottom-up and top-down aspects are integrated.

    The reliable covariation between numerosity and spatial extent is considered as a strong constraint for inferring the successor principle in numerical cognition. We suggest that children can derive a general number concept from the (experientially) infinite succession of spatial positions during object manipulation.
