For Better And Worse: Taking phenomenalist accounts of intuition seriously

The historically-influential perceptual analogy states that intuitions and perceptual experiences are alike in many important respects. Phenomenalists defend a particular reading of this analogy according to which intuitions and perceptual experiences share a common phenomenal character. The phenomenalist thesis has proven highly influential in recent years. However, insufficient attention has been given to the challenges that the phenomenalist thesis raises for theories of intuitions. In this paper, I first develop one such challenge. I argue that if we take seriously the idea that intuitions and perceptual experiences have a common phenomenal character, then an analogous version of the familiar problem of perceptual presence arises for intuitions. I call this the 'problem of intuitive presence'. In the second part of the paper I sketch a novel enactivist solution to this problem.

Epistemological Disjunctivism and the Value of Presence

Epistemological disjunctivists make two strong claims about perceptual experience's epistemic value: (1) experience guarantees the knowledgeable character of perceptual beliefs; (2) experience's epistemic value is “reflectively accessible”. In this paper I develop a form of disjunctivism grounded in a presentational view of experience, on which the epistemic benefits of experience consist in the way perception presents the subject with aspects of her environment. I show that presentational disjunctivism has both dialectical and philosophically fundamental advantages over more traditional expositions. Dialectically, presentational disjunctivism resolves a puzzle disjunctivists face in their posture vis-à-vis skeptical scenarios. More systematically, presentational disjunctivism provides an especially compelling view of disjunctivism as an internalist view of perceptual consciousness by explaining the way perceptual presence manifests the subject's rationality in a distinct way.

Imaginary agents exist perceptually for children but not for adults

Mental imagery refers to representations and the accompanying experience of sensory information in the absence of appropriate sensory input. Little is known about children’s social imagery, imagery about an agent. It is possible that children’s social imagery may qualitatively differ from that of adults by involving more perceptual characteristics. We conducted three experiments to investigate the perceptual existence of social imagery when induced by verbal cues. Experiment 1 was a precondition for Experiments 2 and 3, and we examined whether children’s and adults’ predictive eye movements were disrupted by the presence of a real person’s face. Preschool children (n = 20) and adults (n = 20) watched a video where a woman, with/without her face shown, placed balls into a bucket. Participants’ gazes were less predictive of the woman’s actions in ‘Face’ versus ‘No-Face’ videos, indirectly indicating the perceptual presence of agents. Next, we examined whether adults’ and children’s predictive eye movements were affected by imagining a person. In Experiment 2, adult participants were presented with a video where the balls moved automatically and were asked to either watch the video (Ball condition, n = 20) or imagine that an invisible person moved the balls (Imagination condition, n = 20). Adult gazes did not differ between conditions. However, in Experiment 3, preschool children’s gazes were less predictive when imagining an invisible person’s actions (Invisible condition, n = 20) than when not imagining anything (Ball condition, n = 20) or when imagining an object (Fan condition, n = 20). The results suggest that children experience realistic social imagery induced by verbal cues.

Neurophenomenology of induced and natural synaesthesia

People with synaesthesia have additional perceptual experiences, which are automatically and consistently triggered by specific inducing stimuli. Synaesthesia therefore offers a unique window into the neurocognitive mechanisms underlying conscious perception. A long-standing question in synaesthesia research is whether it is possible to artificially induce non-synaesthetic individuals to have synaesthesia-like experiences. Although synaesthesia is widely considered a congenital condition, increasing evidence points to the potential of a variety of approaches to induce synaesthesia-like experiences, even in adulthood. Here, we summarize a range of methods for artificially inducing synaesthesia-like experiences, comparing the resulting experiences to the key hallmarks of natural synaesthesia which include consistency, automaticity and a lack of ‘perceptual presence’. We conclude that a number of aspects of synaesthesia can be artificially induced in non-synaesthetes. These data suggest the involvement of developmental and/or learning components in the acquisition of synaesthesia, and they extend previous reports of perceptual plasticity leading to dramatic changes in perceptual phenomenology in adults. This article is part of a discussion meeting issue ‘Bridging senses: novel insights from synaesthesia’.

Imaginative Presence

When looking at an object, we perceive only its facing surface, yet we nonetheless perceptually experience the object as a three-dimensional whole. This gives us what Alva Noë has called the problem of perceptual presence, i.e. the problem of accounting for the features of our perceptual experience that are present as absent. Although he proposes that we can best solve this problem by adopting an enactive view of perception, one according to which perceptual presence is to be explained in terms of the exercise of our sensorimotor capacities, this chapter argues that this is a mistake. Rather, we can best account for presence in absence in terms of the exercise of our imaginative capacities.

Phenomenal Presence

Many different features figure consciously in our perceptual experiences, in the sense that they make a subjective difference to those experiences. These features range from colours and shapes to volumes and backsides, from natural or artefactual kinds to reasons for perceptual belief, and from the existence and externality of objects to the relationality and wakefulness of our perceptual awareness of them. The topic of this collection of essays is the different ways in which features like these can be phenomenally present in perceptual experience. In particular, the focus is on features that are less often discussed, and the perceptual presence of which is less obvious because they are out of view or otherwise easily overlooked, features given in a non-sensory manner, and features that are categorical in the sense that they pertain to all perceptual experiences alike (such as their justificatory power, their wakefulness, or the externality of their objects). The book is divided into four parts, each dealing with a different kind of phenomenal presence. The first addresses the nature of the presence of perceptual constancies and variations, while the second investigates the determinacy and ubiquity of the presence of spatial properties in perception. The third part deals with the presence of hidden or occluded aspects of objects, while the last part of the volume discusses the presence of categorical aspects of perceptual experience. Together, the contributions provide a thorough examination of which features are phenomenally present in perception, and what it is for them to figure in experience in this way.
