Alexithymia, a personality trait marked by difficulty in identifying and describing emotions, is associated with differences in interoception - the ability to perceive and interpret internal bodily signals. Interoception plays a key role in forming a coherent sense of self and contributes to body ownership, the feeling that one's body belongs to oneself. This study explored how interoception...

Perception is an important aspect of our personal lives, interpersonal interactions and professional activities and performance. A large body of psychological research has been dedicated to exploring how perception happens, whether and when it involves conscious awareness and what are the physiological correlates, such as skin-conductance and heart-rate responses, that occur when we perceive...
I appreciate item 2, because consciousness implies sapience, whereas perception proper is sentience. Item 4 is clearly irrelevant to the present issue. So we need to consider only items 1 and 3. In item 3 the two subitems are not really different and they rely on the notion of “sensation,” which is an unfortunate concept framed by philosophers (Gassendi, 1658; Russell, 1912). So item 1 is what...
The Sense of Ownership (SoO) and the Sense of Agency (SoA) are two key components of bodily self-consciousness. In this experiment, we investigated how they are affected by variations in the ecological validity of the moving Rubber Hand Illusion (mRHI) paradigm, which typically include three movement conditions: active congruent, passive congruent, and active incongruent. These conditions were...
Illusions are commonly defined as departures of our percepts from the veridical representation of objective, common-sense reality. However, it has been claimed recently that this definition lacks validity, for example, on the grounds that external reality cannot possibly be represented truly by our sensory systems, and indeed may even be a fiction. Here, I first demonstrate how novelist George...

Autonomous sensory meridian response (ASMR) is a pleasant, tingling sensation on the skin that can be elicited by certain auditory and visual stimuli, with the intertwining of sensory modalities and emotional reactions observable in this phenomenon resembling that of synesthesia. The current study shows that the perception of ASMR-associated tingles can be enhanced by means of a prior...
Koenderink (2014, Perception, 43, 1-6) has said most Perception readers are deluded, because they believe an 'All Seeing Eye' observes an objective reality. We trace the source of Koenderink's assertion to his metaphysical idealism, and point to two major weaknesses in his position-namely, its dualism and foundationalism. We counter with arguments from modern philosophy of science for the...
This paper presents the results of some recent experiments in neuroscience and perceptual science that reveal the role of virtual reality in normal visual perception, and the use of television technology by the visual brain. This involves particularly the cholinergic system in the forebrain. This research throws new light on the nature of perception and the relation of phenomenal consciousness...
Perceptual rivalry is an oscillation of conscious experience that takes place despite univarying. if ambiguous, sensory input. Much current interest is focused on the controversy over the neural site of binocular rivalry, a variety of perceptual rivalry for which a number of different cortical regions have been implicated. Debate continues over the relative role of higher levels of processing...
An overview is presented in which visual awareness is regarded as the epitome of the general mind-body problem. An experimental solution of the problem is considered first, followed by a philosophical outlook. It is argued that the scientific approach may eventually discover the neural correlate of visual awareness, but visual perceptions, even simple qualia like 'brightness' or 'color', occur...
Is consciousness sensational inference? The Austrian Cambridge philosopher Ludwig Wittgenstein, in Philosophical Investigations (1953), gives a long, deep, fascinating discussion of sensation and whether it is possible for us to compare our sensations. He also asks whether it is meaningful for a machine to have sensations. The concern is over generalizing from one's own sensation to other...
