Our successful engagement with the world is plausibly underwritten by our sensitivity to affordances in our immediate environment. The considerable literature on affordances focuses almost exclusively on affordances for bodily actions such as gripping, walking or eating. I propose that we are also sensitive to affordances for mental actions such as attending, imagining and counting. My case for this ‘Mental Affordance Hypothesis’ is motivated by a series of examples in which our sensitivity to mental affordances mirrors our sensitivity to bodily (...) affordances. Specifically, subjects perceive opportunities to perform a mental action and their doing so leads, under the right conditions, to the automatic preparation of that action. I conclude by sketching a mental affordance research program that would reinforce my case for the Mental Affordance Hypothesis and establish its ramifications for a number of debates across philosophy and psychology.

The inequitable distribution of domestic and caring labour in different-sex couples has been a longstanding feminist concern. Some have hoped that having both partners at home during the COVID-19 pandemic would usher in a new era of equitable work and caring distributions. Contrary to these hopes, old patterns seem to have persisted. Moreover, studies suggest this inequitable distribution often goes unnoticed by the male partner. This raises two questions. Why do women continue to shoulder a disproportionate amount of housework and (...) childcare despite economic and cultural gains? And why is there a widespread one-sided misrepresentation within different-sex couples about how domestic and caring work is distributed between the two partners? We answer these questions by appealing to affordance perception – the perception of possibilities for action in one's environment. We propose an important gender disparity in the perception of affordances for domestic tasks such as the dishwasher affording emptying, the floor affording sweeping and a mess affording tidying. We argue that this contributes not only to the inequitable distribution of domestic labour but to the frequent invisibility of that labour. We explore the consequences of this hypothesis for resistance and social change. (shrink)

Conservatives claim that all phenomenal properties are sensory. Liberals countenance non-sensory phenomenal properties such as what it’s like to perceive some high-level property, and what it’s like to think that p. A hallmark of phenomenal properties is that they present an explanatory gap, so to resolve the dispute we should consider whether experience has non-sensory properties that appear ‘gappy’. The classic tests for ‘gappiness’ are the invertibility test and the zombifiability test. I suggest that these tests yield conflicting results: non-sensory (...) properties lend themselves to zombie scenarios but not to inversion scenarios. Which test should we trust? Against Carruthers & Veillet (2011), I argue that invertibility is not a viable condition of phenomenality. In contrast, being zombifiable is credibly necessary and sufficient for phenomenality. I conclude that there are non-sensory properties of experience that are ‘gappy’ in the right way, and that liberalism is therefore the most plausible position. (shrink)

In this paper we focus on a kind of perceptual states that we call perceptual motivations, that is, perceptual experiences that plausibly motivate us to act, such as itching, perceptual salience and pain. Itching seems to motivate you to scratch, perceiving a stimulus as salient seems to motivate you to attend to it and feeling a pain in your hand seems to motivate actions such as withdrawing from the painful stimulus. Five main accounts of perceptual motivation are available: Descriptive, Conative, (...) Imperativist, Reflexive and Dual Content views. Some of these have been developed in detail and others are natural extensions of existing views. However, we argue that none provides a satisfactory account of the target perceptual states. Driven by the failings of each account, we identify three conditions that any satisfactory theory of perceptual motivation must meet: Direct Motivational Force, Non-Obligatory Force and Intention-Independent Influence. Then we offer an account that attempts to fulfil these conditions: the Affordance Model. This model of perceptual motivation is premised on the claim that each of the target states involves the perception of a specific affordance for action and the triggering of Automatic Motor Initiations (AMIs). We suggest that AMIs can explain the motivational force of these perceptual states. (shrink)

In this interview, James L. McClelland responds to questions regarding connectionist models of cognition, a theory inspired by information processing in the brain. McClelland explains the distinction between symbolic and non-symbolic processing for a better understanding of mental processes. He argues that connectionist models can perform the computations which we know the brain can perform. In addition, he responds to several general questions on the perspectives of computational models of cognition.

I consider the role of cognitive modeling in cognitive science. Modeling, and the computers that enable it, are central to the field, but the role of modeling is often misunderstood. Models are not intended to capture fully the processes they attempt to elucidate. Rather, they are explorations of ideas about the nature of cognitive processes. In these explorations, simplification is essential—through simplification, the implications of the central ideas become more transparent. This is not to say that simplification has no downsides; (...) it does, and these are discussed. I then consider several contemporary frameworks for cognitive modeling, stressing the idea that each framework is useful in its own particular ways. Increases in computer power (by a factor of about 4 million) since 1958 have enabled new modeling paradigms to emerge, but these also depend on new ways of thinking. Will new paradigms emerge again with the next 1,000‐fold increase? (shrink)

We have reason to believe that phenomenal properties are nothing over and above certain physical properties. However, doubt is cast on this by the apparent epistemic gap that arises for attempts to account for phenomenal properties in physical terms. I argue that the epistemic gap should be divided into two more fundamental conceptual gaps. The first of these pertains to the distinctive subjectivity of phenomenal states, and the second pertains to the intrinsicality of phenomenal qualities. Stoljars ignorance hypothesis (IH) attempts (...) to undermine the epistemic gap by arguing that the apparent inexplicability of the phenomenal is merely a symptom of our limited conception of the non-experiential world. I establish some obstacles to IH, and argue that the correct analysis of the epistemic gap means these obstacles can only partially be overcome. I propose, nonetheless, that IH can still be put to good use as half of a hybrid account of phenomenal consciousness. The proposal combines a self-representationalist account of the subjectivity of phenomenal states with a Russellian version of IH that accommodates the qualitative character of those states. This neo-Russellian ignorance hypothesis (NRIH) credibly undermines the appearance of an epistemic gap between the physical and the phenomenal. (shrink)

In a seminal 1977 article, Rumelhart argued that perception required the simultaneous use of multiple sources of information, allowing perceivers to optimally interpret sensory information at many levels of representation in real time as information arrives. Building on Rumelhart's arguments, we present the Interactive Activation hypothesis—the idea that the mechanism used in perception and comprehension to achieve these feats exploits an interactive activation process implemented through the bidirectional propagation of activation among simple processing units. We then examine the interactive activation (...) model of letter and word perception and the TRACE model of speech perception, as early attempts to explore this hypothesis, and review the experimental evidence relevant to their assumptions and predictions. We consider how well these models address the computational challenge posed by the problem of perception, and we consider how consistent they are with evidence from behavioral experiments. We examine empirical and theoretical controversies surrounding the idea of interactive processing, including a controversy that swirls around the relationship between interactive computation and optimal Bayesian inference. Some of the implementation details of early versions of interactive activation models caused deviation from optimality and from aspects of human performance data. More recent versions of these models, however, overcome these deficiencies. Among these is a model called the multinomial interactive activation model, which explicitly links interactive activation and Bayesian computations. We also review evidence from neurophysiological and neuroimaging studies supporting the view that interactive processing is a characteristic of the perceptual processing machinery in the brain. In sum, we argue that a computational analysis, as well as behavioral and neuroscience evidence, all support the Interactive Activation hypothesis. The evidence suggests that contemporary versions of models based on the idea of interactive activation continue to provide a basis for efforts to achieve a fuller understanding of the process of perception.

Some claim that we are phenomenally aware of our experiences as being our own. Different theorists offer different accounts of how pervasive this sense of mineness is, but what unites them is the claim that such a quality of experience exists. In this paper, I suggest that a compelling case for the existence of the sense of mineness has not yet been made. I then introduce four impediments that any such case must overcome: the Epistemic Impediment; the Representation Impediment; the (...) Function Impediment; and the Malfunction Impediment. Although none of these constitutes a knock-down objection to the thesis that experiences are characterised by a sense of mineness, they each highlight a challenge that advocates of the sense of mineness must address. I propose that any case for mineness should be assessed relative to its ability to overcome these impediments. (shrink)

To understand Self-Representationalism you need to understand its family. Self-Representationalism is a branch of the Meta-Representationalist family, and according to theories in this family what distinguishes conscious mental representations from unconscious mental representations is that conscious ones are themselves the target of a mental meta¬-representational state. A mental state M1 is thus phenomenally conscious in virtue of being suitably represented by some mental state M2. What distinguishes the Self-Representationalist branch of the family is the claim that M1 and M2 must (...) be the same token mental state, so a mental state is phenomenally conscious in virtue of suitably representing itself. This Self-Representationalist branch of the family divides into further branches, giving us specific implementations of the Self-Representationalist approach. But before asking whether we should adopt Self-Representationalism, and in what form, we should reflect on why Meta-Representationalism is an attractive family in the first place. After all, Self-Representationalist theories trade on their family name, claiming to deliver on the promises that drive the Meta-Representationalist approach. The two most important promises of Meta-Representationalism are: a) the promise of capturing the transitivity of consciousness and; b) the promise of rendering consciousness naturalisable. I discuss each in turn. (shrink)

The ubiquity of inner awareness thesis states that all conscious states of normal adult humans are characterised by an inner awareness of that very state. UIA-Backers support this thesis while UIA-Skeptics reject it. At the heart of their dispute is a recalcitrant phenomenological disagreement. UIA-Backers claim that phenomenological investigation reveals ‘peripheral inner awareness’ to be a constant presence in their non-introspective experiences. UIA-Skeptics deny that their non-introspective experiences are characterised by inner awareness, and maintain that inner awareness is only gained (...) when they explicitly introspect. Each camp has put forward a range of arguments designed to resolve this dispute, but I argue that none of these arguments has genuine dialectical purchase. This leads me to develop a compromise position that trades on the contribution that affordances can make to our phenomenology. According to the Affordance Model of inner awareness, all conscious states of normal adult humans are characterised by an affordance of introspectability. In line with the UIA-Skeptic, non-introspective experiences are not characterised by inner awareness. But against the traditional UIASkeptic, non-introspective experiences are characterised by an awareness of the opportunity for introspection. On this view, our capacity to gain inner awareness of our current experience is a ubiquitous feature of our phenomenology. I show how the Affordance Model respects the driving phenomenological intuitions of both the UIA-Backers and the traditional UIA-Skeptics, and suggest that it is able to explain why neither camp achieves an accurate description of how inner awareness figures in their phenomenology.

The study of human intelligence was once dominated by symbolic approaches, but over the last 30 years an alternative approach has arisen. Symbols and processes that operate on them are often seen today as approximate characterizations of the emergent consequences of sub- or nonsymbolic processes, and a wide range of constructs in cognitive science can be understood as emergents. These include representational constructs (units, structures, rules), architectural constructs (central executive, declarative memory), and developmental processes and outcomes (stages, sensitive periods, neurocognitive (...) modules, developmental disorders). The greatest achievements of human cognition may be largely emergent phenomena. It remains a challenge for the future to learn more about how these greatest achievements arise and to emulate them in artificial systems. (shrink)

Affordances are opportunities for action. An appropriately positioned teapot, for example, might afford the act of gripping. Evidence that we perceive affordances in our environment can be found through first-person reflection on our perceptual phenomenology and through third-person theorizing about how subjects select what action to perform. This paper argues for two claims about affordance perception. First, I argue that by experiencing affordances we implicitly experience ourselves as agents with the power to perform the afforded actions. This variety of implicit (...) self-awareness is an important but overlooked aspect of our sense of agency. Second, I argue that among the affordances we experience are affordances for mental action such as attending, imagining, and deliberating. Our awareness of mental affordances helps us to select which mental actions to perform and underwrites our sense of ourselves as mental agents. My case for these two conclusions combines a range of phenomenological and theoretical considerations. (shrink)

According to the virtual self theory, selves are merely virtual entities. On this view, our self-representations do not refer to any concrete object and the self is a merely intentional entity. This contemporary version of the ‘no-self’ theory is driven by a number of psychological and philosophical considerations indicating that our representations of the self are pervasively inaccurate. I present two problems for VST. First, the case for VST fails to rule out a more moderate position according to which the (...) self exists but is systematically misrepresented by us. This position regards the self as a real entity that has illusory appearances, rather than as a hallucinated entity that has a merely intentional existence. Second, I suggest that this ‘illusion model’ of self-misrepresentation is preferable to VST. Advocates of VST must acknowledge the existence of an entity—typically the brain—that is the bearer of our misrepresentations of the self. I argue that, other things being equal, we should regard the bearer of our self-representations as the self, even if that entity diverges dramatically from the way we represent the self to be. So by acknowledging the existence of a bearer of self-representations, advocates of VST are in a poor position to deny the existence of the self. I conclude that VST not only fails to rule out the illusion model, but that we have prima facie reason to prefer the illusion model to VST. (shrink)

This paper explores the idea that popular narrative film can somehow contribute to our philosophical understanding. I identify a number of problems with this 'film as philosophy' thesis and argue that the capacity of film to contribute to philosophy is not as great as many authors think. Specifically, I argue that film can only offer genuinely distinctive insights into philosophical questions *about film* and explore Hitchcock's Rear Window as an example of this.

Kriegel’s self-representationalist theory of phenomenal consciousness pursues two projects. The first is to offer a positive account of how conscious experience arises from physical brain processes. The second is to explain why consciousness misleadingly appears to be irreducible to the physical i.e. to ‘demystify’ consciousness. This paper seeks to determine whether SR succeeds on the second project. Kriegel trades on a distinction between the subjective character and qualitative character of conscious states. Subjective character is the property of being a conscious (...) state at all, while qualitative character determines what it is like to be in that state. Kriegel claims that SR explains why subjective character misleadingly appears irreducible, thereby neutralising the apparent irreducibility of consciousness. I argue that although SR credibly demystifies subjective character, it cannot explain why qualitative character also appears irreducible. I conclude that we should pursue the possibility of a hybrid position that combines SR with an account that does explain the apparent irreducibility of qualitative character. (shrink)

Chalmers (2018) considers a wide range of possible responses to the meta-problem of consciousness. Among them is the ignorance hypothesis -- the view that there only appears to be a hard problem because of our inadequate conception of the physical. Although Chalmers quickly dismisses this view, I argue that it has much greater promise than he recognizes. The plausibility of the ignorance hypothesis depends on how exactly one frames the 'problem intuitions' that a solution to the meta-problem must explain. I (...) argue that problem intuitions are hybrid intuitions that encompass one's intuitive take on the phenomenal and one's intuitive take on the physical. The ignorance hypothesis undermines the second half of these hybrid intuitions. I show how the ignorance hypothesis is preferable to the alternatives and attempt to explain why there is such widespread resistance to this promising position. (shrink)

Phenomenal consciousness presents a distinctive explanatory problem. Some regard this problem as ‘hard’, which has troubling implications for the science and metaphysics of consciousness. Some regard it as ‘easy’, which ignores the special explanatory difficulties that consciousness offers. Others are unable to decide between these two uncomfortable positions. All three camps assume that the problem of consciousness is either easy or hard. I argue against this disjunction and suggest that the problem may be ‘tricky’—that is, partly easy and partly hard. (...) This possibility emerges when we recognise that consciousness raises two explanatory questions. The Consciousness Question concerns why a subject is conscious rather than unconscious. The Character Question concerns why a conscious subject’s experience has the phenomenology it has rather than some other. I explore the possibility of one or other of these explanatory challenges being hard and the other easy, and consider the dialectical ramifications this has for all sides of the debate. (shrink)

Agents are continually faced with two related selection problems: i) the problem of selecting what to do from a space of possible behaviours; ii) the problem of selecting what to attend to from a space of possible attendabilia. We have psychological mechanisms that enable us to solve both types of problem. But do these mechanisms follow different principles or work along the same lines? I argue for the latter. I start from the theory that bodily action is supported by a (...) sensitivity to affordances. Strong evidence suggests that affordances feature in our perception of the world and that affordance perception can trigger the neural preparation of the afforded act. An agent can thus see a teapot as grippable and their doing so can automatically ready a gripping response. Something affords attending for an agent just in case it is a possible target of their focal attention. I argue that we are sensitive to these attentional affordances in much the same way. First I argue that we perceive things as attendable. Second I argue that our doing so can trigger the preparation of shifts in focal attention. My case for this is based on a variety of phenomenological, neurological and behavioural parallels between our sensitivity to bodily affordances and our sensitivity to attentional affordances. This yields a unified account with specific implications for our understanding of attention and affordance perception and general implications for our understanding of how the mind solves selection problems.

Revenge is universal in human cultures, and is essentially personal and retributive. Its moral status is contested, as is its rationality. Revenge is traditionally associated with pleasure, but this association is not accounted for in contemporary philosophical treatments of revenge. Here I supply a theory of normal narcissistic functioning that can explain this association. Normal narcissism is an adaptive form of inter-psychic processing which has to do with the regulation of a coherent set of meta-representations of the agent. It can (...) be given a general account by integrating views drawn from clinical traditions, empirical psychology, and contemporary cognitive neuroscience. I explore the neural correlates of normal narcissism, its characteristic accompanying emotions and pleasures/displeasures, and its fundamental dynamics. It is proposed that this allostatic regulatory system plays a prominent role in retributive behavior, including revenge. Revenge is understood as a form of narcissistic repair, and a variety of puzzles concerning revenge are solved from this point of view. (shrink)

Kantian Humility (KH) holds that the intrinsic properties of objects are unknowable for agents such as ourselves. Categorial properties, such as being an object, present a potential threat to KH. Cowling (2010) argues that knowing KH to be true requires knowledge of categorial properties. However, if such properties are shown to be intrinsic properties, then KH is committed to their being unknowable. I defend KH by presenting three alternative responses to this challenge. First, that categorial properties are not properties in (...) the sense relevant to KH. Second, that if they are properties, they are not intrinsic properties. Third, that if they are intrinsic properties, KH is not committed to their being unknowable. I also show how these responses can be applied to a related objection to KH offered by Moore (2001).

This paper attempts a sympathetic comparison between John Dewey and Richard Rorty. In particular I establish the ways in which both Dewey's and Rorty's aesthetical modes require qualitative starting points (or some indeterminate-event trajectory) as a condition for any poetic/novel movement into the future. I show how Dewey's notions of "indeterminate situation," highlighted in his event-metaphysics, resonates with Rorty's notion of metaphor, and that finally Rorty does in fact (wittingly or not) harbor a place for the noncognitive and nonlinguistic via, (...) interestingly enough, a linguistic device. How Rorty uses his notion of metaphor (inspired by Donald Davidson's groundbreaking work) starts very much to take on the feel of what Dewey meant by "primary experience." My emphasis, then, falls on the necessity to both of their respective pragmatic positions of a qualitative starting point (QSP). In this way, the troubling dualism that has developed between experience and language starts to dissolve. (shrink)

To what extent can film - or individual films - act as a vehicle of or forum for philosophy itself?. Many have responded that films can indeed do philosophy to a substantial degree. Furthermore, it has been claimed that this virtue does not belong solely to ‘art’ films, but that popular cinema too can do philosophy. A case in point is Spike Jonze’s 1999 film Being John Malkovich, the Oscar-winning screenplay of which was written by Charlie Kaufman. The outrageous premise (...) of this comic fantasy is summarised by the film’s protagonist, Craig Schwartz: "There's a tiny door in my office Maxine. It's a portal, and it takes you inside John Malkovich. You see the world through John Malkovich's eyes. And then, after about fifteen minutes, you're spit out into a ditch on the side of the New Jersey Turnpike." The philosophical issues that this scenario raises are manifold. My primary aim in this paper is to follow the film through its exploration of subjectivity, clarifying its insights with the aid of current philosophical work on the topic. Hopefully, this will enhance our understanding both of subjectivity, and of the philosophical relevance of the film. A secondary goal of this enquiry is to provide a clear example of film-as-philosophy, perhaps demonstrating how film contributes something to the philosophical forum that an academic text cannot.

This essay outlines a hierarchical framework of Reality that allows for degrees of Reality. I use Reality (with a capital “R”) to designate reality in a primitive, metaphysical sense. Reality, grounding, and essence are the key elements of the framework presented here. I assume that Reality must have a fundamental level and all fundamental phenomena must be Real. Moreover, I postulate that everything non-fundamental is ultimately grounded in the fundamental Real. But what about the Reality of the non-fundamental? I argue (...) that it is possible for non-fundamental phenomena to be Real, Unreal, or Semi-Real. The framework developed here accommodates these possibilities and illuminates them using the notion of essence. I argue that the essential nature of a phenomenon determines its degree of Reality. The framework does not assume that Reality must have degrees but only that it may have degrees. Its theoretical attractiveness consists in its ability to accommodate many diverse intuitions about grounding, help us better understand and classify theories about grounding, and illuminate Reality and its possible degrees.

Where does the impetus towards ethical theory come from? What drives humans to make values explicit, consistent, and discursively justifiable? This paper situates the demand for ethical theory in human life by identifying the practical needs that give rise to it. Such a practical derivation puts the demand in its place: while finding a home for it in the public decision-making of modern societies, it also imposes limitations on the demand by presenting it as scalable and context-sensitive. This differentiates strong (...) forms of the demand calling for theory from weaker forms calling for less, and contexts where it has a place from contexts where it is out of place. In light of this, subjecting personal deliberation to the demand turns out to involve a trade-off. (shrink)

In this article, I argue that an epistemic question about knowledge of our own phenomenal states encourages a certain metaphysical picture of consciousness according to which phenomenal states are reflexive mental representations. Section 1 describes and motivates the thesis that phenomenal self-knowledge is ‘receptive’: that is, the view that a subject has knowledge of their phenomenal states only insofar as they are inwardly affected by those states. In Sections 2 and 3, I argue that this model of phenomenal self-knowledge is (...) unable to accommodate knowledge of our own phenomenology or knowledge of our own awareness. In Section 4, I seek a non-receptive model of phenomenal self-knowledge. I argue that Kriegel’s Self-Representationalist theory of consciousness is uniquely equipped to show how phenomenal self-knowledge is possible. (shrink)

We share with Anderson & Lebiere (A&L) (and with Newell before them) the goal of developing a domain-general framework for modeling cognition, and we take seriously the issue of evaluation criteria. We advocate a more focused approach than the one reflected in Newell's criteria, based on analysis of failures as well as successes of models brought into close contact with experimental data. A&L attribute the shortcomings of our parallel-distributed processing framework to a failure to acknowledge a symbolic level of thought. (...) Our framework does acknowledge a symbolic level, contrary to their claim. What we deny is that the symbolic level is the level at which the principles of cognitive processing should be formulated. Models cast at a symbolic level are sometimes useful as high-level approximations of the underlying mechanisms of thought. The adequacy of this approximation will continue to increase as symbolic modelers continue to incorporate principles of parallel distributed processing. (shrink)

Debates surrounding the high-level contents of perceptual experience focus on whether weperceive the high-level properties of visual objects, such as the property of being a pine tree. Thispaper considers instead whether we perceive the high-level properties of visual scenes, such asthe property of being a forest. Liberals about the contents of perceptual experience have offered avariety of phenomenal contrast cases designed to reveal how the high-level properties of objectsfigure in our visual experience. I offer a series of equivalent phenomenal contrast (...) cases intendedto show how the high-level properties of visual scenes also figure in visual experience. Thisfirst-person evidence of high-level scene perception is combined with third-person evidence fromthe extensive empirical literature on scene categorisation. Critics of liberalism have attempted todeflate existing phenomenal contrast cases by explaining the contrasts in terms of non-perceptualcontents or in terms of attentional changes. I show that neither response is applicable to mycontrast cases and conclude that we do indeed perceptually experience the high-level propertiesof visual scenes. (shrink)

Jackson’s formulation of the knowledge argument has had an inestimable influence on the discussion of consciousness and the apparent problem it presents for physicalism. A common objection to KA is the ‘ignorance objection’. According to this objection, our intuitions about Mary merely reflect our ignorance of physical facts that are integral to the explanation of phenomenal consciousness. Armed with the insights of a future science, Mary would actually be able to deduce what it’s like to see red. We only have (...) the intuition that Mary would learn something new because we don’t know what she knows. Those sympathetic to KA have brushed away the ignorance objection on the grounds that evstructuren though we don’t know what the future science of consciousness will reveal, we do know what kind of facts it will contain and know that these are the wrong kind of facts from which to deduce facts about phenomenal consciousness. In other words, they suggest that the insight that underwrites KA is ‘future-proof’: it is not the kind of insight that could be displaced by new scientific knowledge. I argue that this strategy for defending KA is dialectically problematic and reveals a fundamental limitation of the Mary thought experiment. (shrink)
