    What is the Replication Crisis a Crisis of?
    Philosophy of Science 1-11. forthcoming.
    In recent debates about the replication crisis, two positions have been dominant: one that focuses on methodological reforms and one that focuses on theory building. This paper takes up the suggestion that there might be a deeper difference in play, concerning the ways the very subject matter of psychology is construed by opposing camps, i.e., in terms of stable effects versus in terms of complexity. I argue that each gets something right, but neither is sufficient. My analysis suggests that the…Read more

    Scientific Concepts and Investigative Practice: Introduction
    In Uljana Feest & Friedrich Steinle (eds.), Scientific Concepts and Investigative Practice, De Gruyter. pp. 1-22. 2012.
  • Progress in psychology
    In Yafeng Shan (ed.), New Philosophical Perspectives on Scientific Progress, Routledge. pp. 184-203. 2022.
    The chapter argues that whereas traditional accounts of progress have typically focused on scientific theories (evaluating them with regards to their truthlikeness or their explanatory and predictive success), we should pay closer attention to efforts of forming and developing scientific concepts (evaluating them with regards to how well such concepts serve the respective aims of research, which can include, but are not limited to, explanation and prediction). If we focus on concepts rather than…Read more

    Carnaps Werk zwischen den späten 1920er- und frühen 1930er-Jahren nimmt verschiedentlich auf Begrifflichkeiten und Debatten der philosophischen und experimentellen Psychologie seiner Zeit Bezug. Diese Bezugnahmen sind jedoch nicht immer konsistent oder explizit. Beispielsweise bedient Carnap sich sowohl im Aufbau als auch in seinen Ausführungen zur Psychologie in einer physikalischen Sprache einiger Grundannahmen der experimentellen Psychologie, führt dies jedoch nicht konsequent zu Ende. Umgeke…Read more

    Data quality, experimental artifacts, and the reactivity of the psychological subject matter
    European Journal for Philosophy of Science 12 (1): 1-25. 2022.
    While the term “reactivity” has come to be associated with specific phenomena in the social sciences, having to do with subjects’ awareness of being studied, this paper takes a broader stance on this concept. I argue that reactivity is a ubiquitous feature of the psychological subject matter and that this fact is a precondition of experimental research, while also posing potential problems for the experimenter. The latter are connected to the worry about distorted data and experimental artifacts…Read more

    In 1932, Rudolf Carnap published his article “Psychology in a Physical Language.” The article prompted a critical response by the Gestalt psychologist Karl Duncker. The exchange is marked by mutual lack of comprehension. In this paper I will provide a contextualized explication of the exchange. I will show that Carnap’s physicalism was deeply rooted in the psychophysical tradition that also informed Gestalt psychological research. By failing to acknowledge this, Carnap missed out on the possibil…Read more

    Construct validity in psychological tests – the case of implicit social cognition
    European Journal for Philosophy of Science 10 (1): 1-24. 2020.
    This paper looks at the question of what it means for a psychological test to have construct validity. I approach this topic by way of an analysis of recent debates about the measurement of implicit social cognition. After showing that there is little theoretical agreement about implicit social cognition, and that the predictive validity of implicit tests appears to be low, I turn to a debate about their construct validity. I show that there are two questions at stake: First, what level of detai…Read more

    We provide an overview of three ways in which the expression “Historical epistemology” (HE) is often understood: (1) HE as a study of the history of higher-order epistemic concepts such as objectivity, observation, experimentation, or probability; (2) HE as a study of the historical trajectories of the objects of research, such as the electron, DNA, or phlogiston; (3) HE as the long-term study of scientific developments. After laying out various ways in which these agendas touch on current debat…Read more

    Combining philosophical and historical scholarship, the articles in this volume focus on scientific concepts, rather than theories, as units of analysis. They thereby contribute to a growing literature about the role of concepts in scientific research. The authors are particularly interested in exploring the dynamics of research; they investigate the ways in which scientists form and use concepts, rather than in what the concepts themselves represent. The fields treated range from mathematics to…Read more

    Gestalt psychology, frontloading phenomenology, and psychophysics
    Synthese 198 (Suppl 9): 2153-2173. 2019.
    In his 1935 book Principles of Gestalt Psychology, Kurt Koffka stated that empirical research in perceptual psychology should begin with “a phenomenological analysis,” which in turn would put constraints on the “true theory.” In this paper, I take this statement as a point of departure to investigate in what sense Gestalt psychologists practiced a phenomenological analysis and how they saw it related to theory construction. I will contextualize the perceptual research in Gestalt psychology vis-a…Read more

    Why Replication is Overrated
    Philosophy of Science 86 (5): 895-905. 2019.
    Current debates about the replication crisis in psychology take it for granted that direct replication is valuable and focus their attention on questionable research practices in regard to statistical analyses. This paper takes a broader look at the notion of replication as such. It is argued that all experimentation/replication involves individuation judgments and that research in experimental psychology frequently turns on probing the adequacy of such judgments. In this vein, I highlight the u…Read more

    Phenomena and Objects of Research in the Cognitive and Behavioral Sciences
    Philosophy of Science 84 (5): 1165-1176. 2017.
    It is commonly held that research efforts in the cognitive and behavioral sciences are mainly directed toward providing explanations and that phenomena figure into scientific practice qua explananda. I contend that these assumptions convey a skewed picture of the research practices in question and of the role played by phenomena. I argue that experimental research often aims at exploring and describing “objects of research” and that phenomena can figure as components of, and as evidence for, suc…Read more

    This is a collection of original papers that look at the ways in which the dichotomy between explanation and understanding was conceptualized by various late 19th- and early 20th-century writers both in Germany and in other (mostly) European countries.

    This paper asks (a) how new scientific objects of research are onceptualized at a point in time when little is known about them, and (b) how those conceptualizations, in turn, figure in the process of investigating the phenomena in question. Contrasting my approach with existing notions of concepts and situating it in relation to existing discussions about the epistemology of experimentation, I propose to think of concepts as research tools. I elaborate on the conception of a tool that informs m…Read more

    The last two decades have seen a rising interest in (a) the notion of a scientific phenomenon as distinct from theories and data, and (b) the intricacies of experimentally producing and stabilizing phenomena. This paper develops an analysis of the stabilization of phenomena that integrates two aspects that have largely been treated separately in the literature: one concerns the skills required for empirical work; the other concerns the strategies by which claims about phenomena are validated. I …Read more
  • The conceptual pair of "Erklären" and "Verstehen" (explanation and understanding) has been an object of philosophical and methodological debates for well over a century. Discussions – to this day – are centered around the question of whether certain objects or issues, such as those dealing with humans or society, require a special approach, different from that of the physical sciences. In the course of such philosophical discussions, we frequently find references to historical predecessors, such…Read more

    Experiment
    In Paul Humphreys (ed.), The Oxford Handbook of Philosophy of Science, Oxford University Press Usa. pp. 274-295. 2016.
    The authors provide an overview of philosophical discussions about the roles of experiment in science. First, they cover two approaches that took shape under the heading of “new experimentalism” in the 1980s and 1990s. One approach was primarily concerned with questions about entity realism, robustness, and epistemological strategies. The other has focused on exploratory experiments and the dynamic processes of experimental research as such, highlighting its iterative nature and drawing out the …Read more

    This paper provides an interpretation of Hans-Jörg Rheinberger’s notions of epistemic things and historical epistemology . I argue that Rheinberger’s approach articulates a unique contribution to current debates about integrated HPS, and I propose some modifications and extensions of this contribution. Drawing on examples from memory research, I show that Rheinberger is right to highlight a particular feature of many objects of empirical research (“epistemic things”)—especially in the contexts o…Read more

    'Hypotheses, everywhere only hypotheses!': on some contexts of Dilthey's critique of explanatory psychology
    Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 38 (1): 43-62. 2005.
    In 1894, Wilhelm Dilthey published an article in which he formulated a critique of what he called ‘explanatory psychology’, contrasting it with his own conception of ‘descriptive psychology’. Dilthey’s descriptive psychology, in turn, was to provide the basis for Dilthey’s specific philosophy of the human sciences (Geisteswissenschaften). In this paper, I contextualize Dilthey’s critique of explanatory psychology. I show that while this critique comes across as very broad and sweeping, he in fac…Read more

    Introspection as a Method and Introspection as a Feature of Consciousness
    Inquiry: An Interdisciplinary Journal of Philosophy 55 (1). 2012.
    Abstract If we take for granted that introspection is indispensable for the study of conscious mental states, the question arises what criteria have to be met in order for introspective reports to qualify as scientific evidence. There have been some attempts to argue (implicitly or explicitly) that it is possible to provide a satisfactory answer to this question while remaining agnostic with respect to questions about the nature of consciousness. Focusing on the aim of using introspection in ord…Read more

    Operationism in Psychology - What the Debate is About, What the Debate Should Be About
    Journal for the Histoty of the Behavioral Sciences 41 (2): 131-150. 2005.
    I offer an analysis of operationism in psychology, which is rooted in an historical study of the investigative practices of two of its early proponents (S. S. Stevens and E. C. Tolman). According to this analysis, early psychological operationists emphasized the importance of experimental operations and called for scientists to specify what kinds of operations were to count as empirical indicators for the referents of their concepts. While such specifications were referred to as “definitions,” I…Read more

    : This paper investigates the way in which Rudolf Carnap drew on Gestalt psychological notions when defining the basic elements of his constitutional system. I argue that while Carnap's conceptualization of basic experience was compatible with ideas articulated by members of the Berlin/Frankfurt school of Gestalt psychology, his formal analysis of the relationship between two basic experiences ("recollection of similarity") was not. This is consistent, given that Carnap's aim was to provide a un…Read more
