Isolated sleep paralysis is a common parasomnia characterized by an inability to move or speak and often accompanied by hallucinations of a sensed presence nearby. Recent research has linked ISP, and sensed presence more particularly, with social anxiety and other psychopathologies. The present study used a large sample of respondents to an internet questionnaire to test whether these associations are due to a general personality factor, affect distress, which is implicated in nightmare suffering and hypothesized to involve dysfunctional social imagery (...) processes. A new measure, ISP distress, was examined in relation to features of ISP experiences, to self-reported psychopathological diagnosis, to scores on the Leibowitz Social Anxiety Scale and to scores on a new questionnaire subscale assessing social imagery in a variety of waking states. Three main results were found: ISP experiences are only weakly associated with a prior diagnosis of mental disorder, sensed presence during ISP is associated preferentially with ISP distress, and ISP distress is associated with dysfunctional social imagery. A general predisposition to affective distress may influence the distress associated with ISP experiences; overly passive social imagery may, in turn, be implicated in this affect distress influence.

The richness and subtlety of the felt presence phenomenon introduced by “Felt Presence: the uncanny encounters with the numinous Other” (Solomonova et al., this issue) offers a challenge to the emerging field of new media. How to create a computer-mediated environment which can engender a spontaneous, creative, and individualized experience such as felt presence? The Other experiment described in this paper explores the possibility of unfolding phenomenological and poetic aura of felt presence experience in a media-rich environment with liminal stimulation, (...) dosed carefully, and open to interpretation.

AimRapid eye movement (REM) sleep, non-rapid eye movement (NREM) sleep, and sleep spindles are all implicated in the consolidation of procedural memories. Relative contributions of sleep stages and sleep spindles were previously shown to depend on individual differences in task processing. However, no studies to our knowledge have focused on individual differences in experience with Vipassana meditation as related to sleep. Vipassana meditation is a form of mental training that enhances proprioceptive and somatic awareness and alters attentional style. The goal (...) of this study was to examine a potential role for Vipassana meditation experience in sleep-dependent procedural memory consolidation.MethodsGroups of Vipassana meditation practitioners (N = 22) and matched meditation-naïve controls (N = 20) slept for a daytime nap in the laboratory. Before and after the nap they completed a procedural task on the Wii Fit balance platform.ResultsMeditators performed slightly better on the task before the nap, but the two groups improved similarly after sleep. The groups showed different patterns of sleep-dependent procedural memory consolidation: in meditators, task learning was positively correlated with density of slow occipital spindles, while in controls task improvement was positively associated with time in REM sleep. Sleep efficiency and sleep architecture did not differ between groups. Meditation practitioners, however, had a lower density of occipital slow sleep spindles tha... (shrink)

This volume proposes an interdisciplinary framework that views attention from a particular angle: as a means of accessing, that is, disclosing the world in a practical and meaningful way. Moreover, it investigates how this access is concretely mediated. The book is structured in the following two parts: 1) Attention and Access The first section is concerned with attention as such. What is attention and what does it do? A common thread between the expected contributions addresses attention as a directional disclosing (...) process, opening up a possibility of access to the world. This section brings contributions from a cognitive psychology/neuroscience into dialogue with phenomenology and philosophy of mind; and links attention research to new paradigms, such as predictive coding, and 4e cognition. 2) Attention and Mediation The second section tackles the question of how this disclosing process may work. Concrete disclosing is always framed by different factors and frames the world. The contributions in this section spell out the different ways in which attention is mediated and shaped by technology, situations, sociality etc., and the ways in which attention mediates our access to the world.

Felt presence, a sensation that “someone is there”, is an integral part of our everyday experience. It can manifest itself in a variety of forms ranging from most subtle fleeting impressions to intense hallucinations of demonic assault or visions of the divine. Felt presence phenomenon outside of the context of neurological disorders is largely neglected and not well understood by contemporary science. This paper focuses on the experiential and expressive qualities of the phenomenon and attempts to bring forth the complexity (...) and the richness of possibilities for inter- and intrasubjective awareness represented by these experiences. Are these simply misperceptions and hallucinations heightened and enforced by the mystical or superstitious mind? Or are these entities projections of our own “selves”, elements of self-estrangement? How are such experiences shaping our understanding of ourselves and of others? And finally, what is the interplay between intersubjective, private experiences and private or public spaces of dwelling? (shrink)
