Epistemology Of Perception

AbstractIn this paper, I use the predictive processing (PP) theory of perception to tackle the question of how perceptual states can be rationally involved in cognition by justifying other mental states. I put forward two claims regarding the epistemological implications of PP. First, perceptual states can confer justification on other mental states because the perceptual states are themselves rationally acquired. Second, despite being inferentially justified rather than epistemically basic, perceptual states can still be epistemically responsive to the mind-independent world. My main goal is to elucidate the epistemology of perception already implicit in PP. But I also hope to show how it is possible to peacefully combine central tenets of foundationalist and coherentist accounts of the rational powers of perception while avoiding the well-recognized pitfalls of either.

Mentalizing System

AbstractWord of mouth recommendations influence a wide range of choices and behaviors. What takes place in the mind of recommendation receivers that determines whether they will be successfully influenced? Prior work suggests that brain systems implicated in assessing the value of stimuli (i.e., subjective valuation) and understanding others’ mental states (i.e., mentalizing) play key roles. The current study used neuroimaging and natural language classifiers to extend these findings in a naturalistic context and tested the extent to which the two systems work together or independently in responding to social influence. First, we show that in response to text-based social media recommendations, activity in both the brain’s valuation system and mentalizing system was associated with greater likelihood of opinion change. Second, participants were more likely to update their opinions in response to negative, compared to positive, recommendations, with activity in the mentalizing system scaling with the negativity of the recommendations. Third, decreased functional connectivity between valuation and mentalizing systems was associated with opinion change. Results highlight the role of brain regions involved in mentalizing and positive valuation in recommendation propagation, and further show that mentalizing may be particularly key in processing negative recommendations, whereas the valuation system is relevant in evaluating both positive and negative recommendations.

AbstractThe Bayesian brain hypothesis provides an attractive unifying framework for perception, cognition, and action. We argue that the framework can also usefully integrate interoception, the sense of the internal physiological condition of the body. Our model of “interoceptive predictive coding” entails a new view of emotion as interoceptive inference and may account for a range of psychiatric disorders of selfhood.

This paper argues that the still-emerging paradigm of situated cognition requires a more systematic perspective on media to capture the enculturation of the human mind. By virtue of being media, cultural artifacts present central experiential models of the world for our embodied minds to latch onto. The paper identifies references to external media within embodied, extended, enactive, and predictive approaches to cognition, which remain underdeveloped in terms of the profound impact that media have on our mind. To grasp this impact, I propose an enactive account of media that is based on expansive habits as media-structured, embodied ways of bringing forth meaning and new domains of values. We apply such habits, for instance, when seeing a picture or perceiving a movie. They become established through a process of reciprocal adaptation between media artifacts and organisms and define the range of viable actions within such a media ecology. Within an artifactual habit, we then become attuned to a specific media work (e.g., a TV series, a picture, a text, or even a city) that engages us. Both the plurality of habits and the dynamical adjustments within a habit require a more flexible neural architecture than is addressed by classical cognitive neuroscience. To detail how neural and media processes interlock, I will introduce the concept of neuromediality and discuss radical predictive processing accounts that could contribute to the externalization of the mind by treating media themselves as generative models of the world. After a short primer on general media theory, I discuss media examples in three domains: pictures and moving images; digital media; architecture and the built environment. This discussion demonstrates the need for a new cognitive media theory based on enactive artifactual habits—one that will help us gain perspective on the continuous re-mediation of our mind.

A mental state is luminous if and only if being in a state of that kind always puts one in a position to know that one is in the state. This chapter is a critique of Timothy Williamson’s margin-of-error argument that no nontrivial states are luminous in this sense. While I agree with Williamson’s rejection of a Cartesian internalist conception of the mind, I argue that an externalist conception (one based on information theory) can be reconciled with the luminosity of intentional mental states such as knowledge. My argument, which uses an artificial and simplified model of knowledge, is not a direct rebuttal to his argument, as applied to a more realistic notion of the knowledge of human beings, but I argue that it shows that a luminosity assumption is compatible with externalism about knowledge, and it suggest an intuitively plausible strategy for resisting his argument.

The Mind

Materialism – which, for almost all purposes, is the same as physicalism – is the theory that everything that exists is material. Natural science shows that most things are intelligible in material terms, but mind presents problems in at least two ways. The first is consciousness, as found in the ‘raw feel’ of subjective experience. The second is the intentionality of thought, which is the property of being about something beyond itself; ‘aboutness’ seems not to be a physical relation in the ordinary sense. There have been three ways of approaching these problems. The hardest is eliminativism, according to which there are no ‘raw feels’, no intentionality and, in general, no mental states: the mind and all its furniture are part of an outdated science that we now see to be false. Next is reductionism, which seeks to give an account of our experience and of intentionality in terms which are acceptable to a physical science: this means, in practice, analysing the mind in terms of its role in producing behaviour. Finally, the materialist may accept the reality and irreducibility of mind, but claim that it depends on matter in such an intimate way – more intimate than mere causal dependence – that materialism is not threatened by the irreducibility of mind. The first two approaches can be called ‘hard materialism’, the third ‘soft materialism’. The problem for eliminativism is that we find it difficult to credit that any belief that we think and feel is a theoretical speculation. Reductionism’s main difficulty is that there seems to be more to consciousness than its contribution to behaviour: a robotic machine could behave as we do without thinking or feeling. The soft materialist has to explain supervenience in a way that makes the mind not epiphenomenal without falling into the problems of interactionism.

The Brain

We know that the brain is intimately connected with mental activity. Indeed, doctors now define death in terms of the cessation of the relevant brain activity. The identity theory of mind holds that the intimate connection is identity: the mind is the brain, or, more precisely, mental states are states of the brain. The theory goes directly against a long tradition according to which mental and material belong to quite distinct ontological categories – the mental being essentially conscious, the material essentially unconscious. This tradition has been bedevilled by the problem of how essentially immaterial states could be caused by the material world, as would happen when we see a tree, and how they could cause material states, as would happen when we decide to make an omelette. A great merit of the identity theory is that it avoids this problem: interaction between mental and material becomes simply interaction between one subset of material states, namely certain states of a sophisticated central nervous system, and other material states. The theory also brings the mind within the scope of modern science. More and more phenomena are turning out to be explicable in the physical terms of modern science: phenomena once explained in terms of spells, possession by devils, Thor’s thunderbolts, and so on, are now explained in more mundane, physical terms. If the identity theory is right, the same goes for the mind. Neuroscience will in time reveal the secrets of the mind in the same general way that the theory of electricity reveals the secrets of lightning. This possibility has received enormous support from advances in computing. We now have at least the glimmerings of an idea of how a purely material or physical system could do some of the things minds can do. Nevertheless, there are many questions to be asked of the identity theory. How could states that seem so different turn out to be one and the same? Would neurophysiologists actually see my thoughts and feelings if they looked at my brain? When we report on our mental states what are we reporting on – our brains?

The relevance of chaotic itinerancy and other types of exotic dynamical behavior described by Tsuda (2001) certainly goes beyond the scope of his target article. These concepts of dynamics may offer a general framework for the understanding of complexity, which could help to restructure the analysis and conceptualization of mental states in novel ways, providing insights for the philosophy of mind.

Feedback Cues

For decades, a common assumption in cognitive neuroscience has been that prefrontal executive control is mainly engaged during target detection [Posner, M. I., & Petersen, S. E. The attention system of the human brain. Annual Review of Neuroscience, 13, 25–42, 1990]. More recently, predictive processing theories of frontal function under the Bayesian brain hypothesis emphasize a key role of proactive control for anticipatory action selection (i.e., planning as active inference). Here, we review evidence of fast and widespread EEG and magnetoencephalographic fronto-temporo-parietal cortical activations elicited by feedback cues and target cards in the Wisconsin Card Sorting Test. This evidence is best interpreted when considering negative and positive feedback as predictive cues (i.e., sensory outcomes) for proactively updating beliefs about unknown perceptual categories. Such predictive cues inform posterior beliefs about high-level hidden categories governing subsequent response selection at target onset. Quite remarkably, these new views concur with Don Stuss' early findings concerning two broad classes of P300 cortical responses evoked by feedback cues and target cards in a computerized Wisconsin Card Sorting Test analogue. Stuss' discussion of those P300 responses—in terms of the resolution of uncertainty about response (policy) selection as well as the participants' expectancies for future perceptual or motor activities and their timing—was prescient of current predictive processing and active (Bayesian) inference theories. From these new premises, a domain-general frontoparietal cortical network is rapidly engaged during two temporarily distinct stages of inference and learning of perceptual categories that underwrite goal-directed card sorting behavior, and they each engage prefrontal executive functions in fundamentally distinct ways.

Metaphysics Of Mind

Philosophy of mind addresses fundamental questions about mental or psychological phenomena. The question held by many to be most fundamental of all is a metaphysical one, often labeled the “mind-body problem,” which concerns the relation between minds and material or physical phenomena. Physicalists (and/or materialists) contend that mental phenomena are physical, or at least that they may be accounted for in terms of physical phenomena (brains, for example). Dualists deny this, maintaining that mental phenomena have fundamentally nonphysical natures, so that to account for minds we must assume the existence of nonphysical substances or properties. Nowadays physicalism is more widely espoused than dualism, but physicalists differ over which physical states/properties should be considered relevant, and over the precise nature of the relation between physical and mental phenomena. This is one of four bibliography entries on the philosophy of mind, and this particular entry concentrates on this metaphysical issue of the relation between mental and physical/material phenomena. Inevitably, there is a good deal of overlap between this and topics covered in the other three entries. For example, this entry includes authors who attack physicalism by arguing that it cannot account for the distinctive phenomenal qualities of conscious experiences; but that line of antiphysicalist argument features even more prominently in the entry on consciousness. Moreover, the other entries feature various issues that might perfectly properly be categorized as concerning the metaphysics of mind: for example, the debate between internalists—philosophers who hold that propositional attitudes (mental states such as beliefs and desires, which have representational contents) are intrinsic properties of minds/brains—and externalists, who think of certain attitudes as extrinsic or relational, is surely a question about the metaphysics of mind: but this is discussed in the entry on intentionality instead of here.

The Relationship

<p>Dualists view the mind and the body as two fundamental different “things”, equally real and independent of each other. Cartesian thought, or substance dualism, maintains that the mind and body are two different substances, the non-physical and the physical, and a causal relationship is assumed to exist between them. Physicalism, on the other hand, is the idea that everything that exists is either physical or totally dependent of and determined by physical items. Hence, all mental states are fundamentally physical states. In the current study we investigated to what degree Swedish university students’ beliefs in mind-body dualism is explained by the importance they attach to personal values. A self-report inventory was used to measure their beliefs and values. Students who held stronger dualistic beliefs attach less importance to the power value (i.e., the effort to achieve social status, prestige, and control or dominance over people and resources). This finding shows that the strength in laypeople’s beliefs in dualism is partially explained by the importance they attach to personal values.</p>
