For well over two decades, Andy Clark has been gleaning theoretical lessons from the leading edge of cognitive science, applying a combination of empirical savvy and philosophical instinct that few can match. Clark’s most recent book, Supersizing the Mind: Embodiment, Action, and Cognitive Extension, brilliantly expands his oeuvre. It offers a well-informed and focused survey of research in the burgeoning field of situated cognition, a field that emphasizes the contribution of environmental and non-neural bodily structures to the production of intelligent (...) behavior. The situated research program, fledgling though it may be in some respects, has reached an age at which its philosophical stock can reasonably be taken; and Clark is just the person to take it. Supersizing the Mind consists of three main divisions. The first develops the case for the distinctively extended view of cognition, according to which the human mind or cognitive system literally comprises elements beyond the boundary of the human organism. The second responds to critics of the extended outlook: Frederick Adams, Kenneth Aizawa, Keith Butler, Brie Gertler, Rick Grush, and me, among others. The third major division evaluates nonextended strands in the situated program, in particular, those that emphasize the role of the non-neural body in cognition. (shrink)

This essay presents the conditional probability of co-contribution account of the individuation of cognitive systems (CPC) and argues that CPC provides an attractive basis for a theory of the cognitive self. The argument proceeds in a largely indirect way, by emphasizing empirical challenges faced by an approach that relies entirely on predictive processing (PP) mechanisms to ground a theory of the cognitive self. Given the challenges faced by PP-based approaches, we should prefer a theory of the cognitive self of the (...) sort CPC offers, one that accommodates variety in the kinds of mechanism that, when integrated, constitute a cognitive system (and thus the cognitive self), to a theory according to which the cognitive self is composed of essentially one kind of thing, for instance, prediction-error minimization mechanisms. The final section focuses on one of the central functions of the cognitive self: to engage in conscious reasoning. It is argued that the phenomenon of conscious, deliberate reasoning poses an apparently insoluble problem for a PP-based view, one that seems to rest on a structural limitation of predictive-processing models. In a nutshell, conscious reasoning is a single-stream phenomenon, but, in order for PP to apply, two streams of activity must be involved, a prediction stream and an input stream. Thus, with regard to the question of the nature of the self, PP-based views must yield to an alternative approach, regardless of whether proponents of the predictive processing, as a comprehensive theory of cognition, can handle the various empirical challenges canvassed in the preceding section.

Neil Levy offers the most prominent moral principles that are specifically and exclusively designed to apply to neuroethics. His two closely related principles, labeled as versions of the ethical parity principle , are intended to resolve moral concerns about neurological modification and enhancement [1]. Though EPP is appealing and potentially illuminating, we reject the first version and substantially modify the second. Since his first principle, called EPP , is dependent on the contention that the mind literally extends into external props (...) such as paper notebooks and electronic devices, we begin with an examination of the extended mind hypothesis and its use in Levy’s EPP . We argue against reliance on EMH as support for EPP . We turn to his second principle, EPP , which is not dependent on EMH but is tied to the acceptable claim that the mind is embedded in, because dependent on, external props. As a result of our critique of EPP , we develop a modified version of EPP , which we argue is more acceptable than Levy’s principle. Finally, we evaluate the applicability of our version of EPP.

The notion of cognitive system is widely used in explanations in cognitive psychology and neuroscience. Traditional approaches define cognitive systems in an agent-relative way, that is, via top-down functional decomposition that assumes a cognitive agent as starting point. The extended cognition movement challenged that approach by questioning the primacy of the notion of cognitive agent. In response, [Adams, F., and K. Aizawa. 2001. The Bounds of Cognition. Oxford, UK: Wiley-Blackwell.] suggested that to have a clear understanding of what a cognitive (...) system is we may need to solve “the demarcation challenge”: the problem of identifying a reliable way to determine which mechanisms that are causally responsible for the production of a certain cognitive process constitute a cognitive system responsible for such process and which ones do not. Recently, [Rupert, R. 2009. Cognitive Systems and the Extended Mind. Oxford: Oxford University Press.] offered a solution based on the idea that the mechanisms that constitute a cognitive system are integrated in a particular sense. In this paper I critically review Rupert’s solution and argue against it. Additionally, I argue that a successful account of cognitive system must accommodate the fact that the neural mechanisms causally responsible for the production of a cognitive process are diachronically dynamic and yet functionally stable. At the end, I offer a suggestion as to how to accommodate this diachronic dynamicity without losing functional stability. I conclude by drawing some implications for the discussion on cognitive ontologies. (shrink)

Clinically significant delusion is a symptom of a number of mental illnesses. We rely on what a person says and how she behaves in order to identify if she has this symptom and it is clear from the literature that delusions are heterogeneous and extremely difficult to define. People with active delusions were interviewed to explore what it is like to develop and experience delusion. The transcribed interview data was analysed to identify themes and narrative trajectories that help to explain (...) the phenomenon. Results showed that delusions can sometimes provide pragmatic benefits and that the genesis of some delusions can be characterised in terms of the enactivist notion of affective framing. Affective framing is a term that captures the background emotions that enable know-how in terms of goal directed action and cognition. If a person’s affective frame alters the world is no longer understood and know-how is lost. The way in which a person relates to her environment can be highly anomalous thus requiring her to find an extraordinary explanation. I argue that delusions arise as a result of a breakdown in affective framing and offer a conceptualisation of delusion supported by empirical findings. (shrink)
