Worlds Apart? Reassessing von Uexküll’s Umwelt in Embodied Cognition with Canguilhem, Merleau-Ponty, and Deleuze

Jakob von Uexküll’s (1864-1944) account of Umwelt has been proposed as a mediating concept to bridge the gap between ecological psychology’s realism about environmental information and enactivism’s emphasis on the organism’s active role in constructing the meaningful world it inhabits. If successful, this move would constitute a significant step towards establishing a single ecological-enactive framework for cognitive science. However, Uexküll’s thought itself contains different perspectives that are in tension with each other, and the concept of Umwelt is developed in representationalist terms that conflict with the commitments of both enactivism and ecological psychology. One central issue shared by all these approaches is the problem of how a living being experiences its environment. In this paper, we will look at Uexküll’s reception in French philosophy and highlight the different ways in which the concept of Umwelt functions in the work of Georges Canguilhem, Maurice Merleau-Ponty, and Gilles Deleuze. This analysis helps clarify different aspects of Uexküll’s thought and the deeper philosophical implications of importing his concepts into embodied cognitive science. This paper is part of a recent trend in which enactivism engages with continental philosophy in a way that both deepens and transcends the traditional links to phenomenology, including most recently the thought of Georg W. F. Hegel and Gilbert Simondon. However, no more than a brief outline and introduction to the potentials and challenges of this complex conceptual intersection can be given here. Our hope is that it serves to make more explicit the philosophical issues that are at stake for cognitive science in the question of experienced environments, while charting a useful course for future research

An Exploration of Representational Complexity via Coupled Oscillators

Abstract We note some inconsistencies in a view of representation which takes decoupling to be of key importance. We explore these inconsistencies using examples of representational vehicles taken from coupled oscillator theory and suggest a new wayto reconcile coupling with absence. Finally, we tie these views to a teleological definition of representation

A Demonstration of the Transition from Ready-to-Hand to Unready-to-Hand

The ideas of continental philosopher Martin Heidegger have been influential in cognitive science and artificial intelligence, despite the fact that there has been no effort to analyze these ideas empirically. The experiments reported here are designed to lend empirical support to Heidegger's phenomenology and more specifically his description of the transition between ready-to-hand and unready-to-hand modes in interactions with tools. In experiment 1, we found that a smoothly coping cognitive system exhibits type positively correlated noise and that its correlated character is reduced when the system is perturbed. This indicates that the participant and tool constitute a self-assembled, extended device during smooth coping and this device is disrupted by the perturbation. In experiment 2, we examine the re-organization of awareness that occurs when a smoothly coping, self-assembled, extended cognitive system is perturbed. We found that the disruption is accompanied by a change in attention which interferes with participants' performance on a simultaneous cognitive task. Together these experiments show that a smoothly coping participant-tool system can be temporarily disrupted and that this disruption causes a change in the participant's awareness. Since these two events follow as predictions from Heidegger's work, our study offers evidence for the hypothesized transition from readiness-to-hand to unreadiness-to-hand

Defending extended cognition

Abstract In this paper, we defend extended cognition against several criticisms. We argue that extended cognition does not derive from armchair theorizing and that it neither ignores the results of the neural sciences, nor minimizes the importance of the brain in the production of intelligent behavior. We also argue that explanatory success in the cognitive sciences does not depend on localist or reductionist methodologies; part of our argument for this is a defense of what might be called 'holistic science'

Word frequency effects found in free recall are rather due to Bayesian surprise

The inconsistent relation between word frequency and free recall performance (sometimes a positive one, sometimes a negative one, and sometimes no relation) and the non-monotonic relation found between the two cannot all be explained by current theories. We propose a theoretical framework that can explain all extant results. Based on an ecological psychology analysis of the free recall situation in terms of environmental and informational resources available to the participants, we propose that because participants’ cognitive system has been shaped by their native language, free recall performance is best understood as the end result of relational properties that preexist the experimental situation and of the way the words from the experimental list interact with those. In addition to this, we borrow from predictive coding theory the idea that the brain constantly predicts “what is coming next” so that it is mainly prediction errors that will propagate information forward. Our ecological psychology analysis indicates there will be “prediction errors” because the word frequency distribution in an experimental word list is inevitably different from the particular Zipf’s law distribution of the words in the language that shaped participants’ brains. We further propose the particular distributional discrepancies inherent to a given word list will trigger, as a function of the words that are included in the list, their order, and of the words that are absent from the list, a surprisal signal in the brain, something that is isomorphic to the concept of Bayesian surprise. The precise moment when Bayesian surprise is triggered will determine to what word of the list that Bayesian surprise will be associated with, and the word the Bayesian surprise will be associated with will benefit from it and become more memorable as a direct function of the magnitude of the surprisal. Two experiments are presented that show a proxy of Bayesian surprise explains the free recall performance and that no effect of word frequency is found above and beyond the effect of that proxy variable. We then discuss how our view can account for all data extant in the literature on the effect of word frequency on free recall

Explanatory Pluralism: A Case Study from the Life Sciences

The predominant view in the contemporary philosophies of the life sciences is that the most fundamental and viable kinds of explanations are mechanistic. In fact, some philosophers of the life science have claimed that the only genuine explanations in the life sciences are mechanistic. We believe this to be an unnecessarily restrictive position, both descriptively and normatively. Descriptively, much actual scientific research in the life sciences is not readily cast as mechanistic. There are many natural phenomena that benefit from the application of multiple explanatory strategies, even at the same scale of investigation. Thus, normatively speaking, research in the life sciences ought to begin from a pluralistic position concerning explanatory style. We defend this claim by means of the application of both mechanistic and dynamical explanatory strategies to bird flocking

Philosophy for the rest of cognitive science

Abstract Cognitive science has always included multiple methodologies and theoretical commitments. The philosophy of cognitive science should embrace, or at least acknowledge, this diversity. Bechtel's (2009a) proposed philosophy of cognitive science, however, applies only to representationalist and mechanist cognitive science, ignoring the substantial minority of dynamically oriented cognitive scientists. As an example of nonrepresentational, dynamical cognitive science, we describe strong anticipation as a model for circadian systems (Stepp & Turvey, 2009). We then propose a philosophy of science appropriate to nonrepresentational, dynamical cognitive science
