Sketch this: extended mind and consciousness extension

This paper will defend the claim that, under certain circumstances, the material vehicles responsible for an agent’s conscious experience can be partly constituted by processes outside the agent’s body. In other words, the consciousness of the agent can extend. This claim will be supported by the Extended Mind Thesis (EMT) example of the artist and their sketchpad (Clark 2001, 2003). It will be argued that if this example is one of EMT, then this example also supports an argument for consciousness extension. Clark (2009) rejects claims of consciousness extension. This paper will challenge Clark and argue that he fails to show that the material vehicles responsible for consciousness must be internal to the agent.     

The extended mind argument against phenomenal intentionality

Phenomenology and the Cognitive Sciences - This paper offers a novel argument against the phenomenal intentionality thesis (or PIT for short). The argument, which I'll call the extended mind...     

Rethinking neuroethics in the light of the extended mind thesis

The extended mind thesis is the claim that mental states extend beyond the skulls of the agents whose states they are. This seemingly obscure and bizarre claim has far-reaching implications for neuroethics, I argue. In the first half of this article, I sketch the extended mind thesis and defend it against criticisms. In the second half, I turn to its neuroethical implications. I argue that the extended mind thesis entails the falsity of the claim that interventions into the brain are especially problematic just because they are internal interventions, but that many objections to such interventions rely, at least in part, on this claim. Further, I argue that the thesis alters the focus of neuroethics, away from the question of whether we ought to allow interventions into the mind, and toward the question of which interventions we ought to allow and under what conditions. The extended mind thesis dramatically expands the scope of neuroethics: because interventions into the environment of agents can count as interventions into their minds, decisions concerning such interventions become questions for neuroethics.     

Collective memory, group minds, and the extended mind thesis

While memory is conceptualized predominantly as an individual capacity in the cognitive and biological sciences, the social sciences have most commonly construed memory as a collective phenomenon. Collective memory has been put to diverse uses, ranging from accounts of nationalism in history and political science to views of ritualization and commemoration in anthropology and sociology. These appeals to collective memory share the idea that memory “goes beyond the individual” but often run together quite different claims in spelling out that idea. This paper reviews a sampling of recent work on collective memory in the light of emerging externalist views within the cognitive sciences, and through some reflection on broader traditions of thought in the biological and social sciences that have appealed to the idea that groups have minds. The paper concludes with some thoughts about the relationship between these kinds of cognitive metaphors in the social sciences and our notion of agency.     

Empty and extended craving: an application of the extended mind thesis to the four noble truths

According to Buddhism's four noble truths, (1) we find our lives filled with anguished suffering because (2) we habitually crave for life to be other than it is; and (3) this habit of craving will cease (4) only if we cultivate in our lives the Buddha's path of mental discipline, wisdom, and moral conduct. The aim of Buddhist practice is to cure craving. There is a model of the self that can be derived from the recent work of some philosophers in the field of cognitive science, Andy Clark in particular. His writings suggest a model of the self that is spread out or extended. I will argue that the model of the extended self offers contemporary insight for interpreting what craving is in the Buddhist sense and how to cure it.     

Superdupersizing the mind: extended cognition and the persistence of cognitive bloat

The hypothesis of extended cognition (EC) contends that parts of the world outside of the head partly comprise the vehicles of representation and mind. I consider and reject recent efforts to defend EC from the problem of “cognitive bloat.”     

Exposure to the social sharing of emotion: Emotional impact,listener responses and secondary social sharing

In line with evidence showing that emotion involves a social sharing process in which the subject communicates about emotional experience, this article examines the impact of being exposed to such communications. First, it was predicted that being exposed to the social sharing of an emotion is emotion-inducing. Second, it was reasoned that if this holds true, then the listener should later engage in socially sharing with other persons the emotional narrative heard. Thus, a process of ‘secondary social sharing’ was predicted. In two independent studies subjects recalled a situation in which someone had shared an emotional experience with them. They then rated emotions felt while exposed to the narrative, responses adopted toward the sharing person, and extent of secondary social sharing. The predictions were supported. Exposure to a social sharing situation was confirmed as itself emotion-inducing. Secondary social sharing was recorded in 66 per cent of the cases in Study 1 and in 78 per cent in Study 2. Both studies also showed that exposure to the sharing of highly intense emotional episodes elicited more repetitive secondary social sharing and a superior number of target persons than exposure to episodes of low or of moderate emotional intensity. © 1997 by John Wiley & Sons, Ltd.     

Externalized memory in slime mould and the extended (non-neuronal) mind

The hypothesis of extended cognition (HEC) claims that the cognitive processes that materially realise thinking are sometimes partially constituted by entities that are located external to an agent’s body in its local environment. We show how proponents of HEC need not claim that an agent must have a central nervous system, or physically instantiate processes organised in such a way as to play a causal role equivalent to that of the brain if that agent is to be capable of cognition. Focusing on the case of spatial memory, we make our argument by taking a close look at the striking example of Physarum Polycephalum plasmodium (i.e., slime mould) which uses self-produced non-living extracellular slime trails to navigate its environment. We will argue that the use of externalized spatial memory by basal organisms like Physarum is an example of extended cognition. Moreover, it is a possible evolutionary precursor to the use of internal spatial memory and recall in animals thus demonstrating how extended cognition may have emerged early in evolutionary history.     

Out of our skulls: How the extended mind thesis can extend psychiatry

The thesis that mental states extend beyond the skull, otherwise known as the extended mind thesis (ExM), has attracted considerable philosophical attention and support. It has also been accused of lacking practical import. At the same time, the field of psychiatry has remained largely unacquainted with ExM, tending to rely instead upon what ExM proponents would consider to be outdated models of the mind. ExM and psychiatry, therefore, have much to offer one another, but the connection between the two has remained largely unexplored. Here, I consider what implications ExM may have for psychiatry and, in so doing, reveal how psychiatry may lend practical import to ExM. First, I detail the possibility of the extension of one mental state relevant to psychiatry. I augment this example by surveying other possibilities for extension in the context of psychiatric diagnoses. I then consider ways in which such extensions might alter psychiatric diagnosis and treatment. Overall, I argue that recognition of the truth of ExM could alter the diagnostic status of certain individuals by correcting both false positives and false negatives, re-conceptualize certain aspects of treatment, help us re-envision psychiatric research, and potentially increase empathy towards those individuals considered to be mentally disordered or mentally different.     

The molecules of social recognition memory: implications for social cognition, extended mind, and neuroethics

Social cognition, cognitive neuroscience, and neuroethics have reached a synthesis of late, but some troubling features are present. The neuroscience that currently dominates the study of social cognition is exclusively cognitive neuroscience, as contrasted with the cellular and increasingly molecular emphasis that has gripped mainstream neuroscience over the past three decades. Furthermore, the recent field of molecular and cellular cognition has begun to unravel some molecular mechanisms involved in social cognition, especially pertaining to the consolidation of memories of particular conspecific organisms. Some new experimental techniques for positive interventions into these hypothesized mechanisms offer opportunities for establishing direct causal linkages between intra-neuronal molecular events and the behaviors used to measure social cognitive phenomena. Predicted results from an experiment described below also cast doubt on the application of the “extended mind” approach from recent cognitive science to ground the neuroscience of social cognition. Since neuroethics relies heavily on our best neuroscience of social cognition, that field may soon need to extend its attention beyond cognitive neuroscience, and into neuroscience’s cellular and molecular mainstream.     

Pragmatism and the predictive mind

Predictive processing and its apparent commitment to explaining cognition in terms of Bayesian inference over hierarchical generative models seems to flatly contradict the pragmatist conception of mind and experience. Against this, I argue that this appearance results from philosophical overlays at odd with the science itself, and that the two frameworks are in fact well-poised for mutually beneficial theoretical exchange. Specifically, I argue: first, that predictive processing illuminates pragmatism’s commitment to both the primacy of pragmatic coping in accounts of the mind and the profound organism-relativity of experience; second, that this pragmatic, “narcissistic” character of prediction error minimization undermines its ability to explain the distinctive normativity of intentionality; and third, that predictive processing therefore mandates an extra-neural account of intentional content of exactly the sort that pragmatism’s communitarian vision of human thought can provide.     

Functional integration and the mind

Different cognitive functions recruit a number of different, often overlapping, areas of the brain. Theories in cognitive and computational neuroscience are beginning to take this kind of functional integration into account. The contributions to this special issue consider what functional integration tells us about various aspects of the mind such as perception, language, volition, agency, and reward. Here, I consider how and why functional integration may matter for the mind; I discuss a general theoretical framework, based on generative models, that may unify many of the debates surrounding functional integration and the mind; and I briefly introduce each of the contributions.
