Most animals have mental states of one sort or another, but few species share our capacity for self-awareness. We are aware of our own mental states via introspection, and we are aware of the mental states of our fellow human beings on the basis of what they do and say. This chapter is not concerned with these traditional forms of mind-reading—forms whose origins predate the beginnings of recorded history—but with the prospects of a rather different and significantly more recent form (...) of ‘mind-reading’: the capacity to ascribe mental states to a creature on the basis of information derived from neuroimaging.

The aim of this article is to enquire into neuroscientific research on memory and relate it to topics of skill, knowledge and consciousness. The article outlines some contemporary theories on procedural and working memory, and discusses what contributions they give to sport science and philosophy of sport. It is argued that memory research gives important insights to the neuronal structures and events involved in knowledge and consciousness contributing to sport skills, but that these explanations are not exhaustive. The article argues (...) that phenomenal consciousness in skills is not explained by the neuroscience of memory, and hence neither are skills. (shrink)

Clinical delusions are difficult to investigate in the laboratory because they co-occur with other symptoms and with intellectual impairment. Partly for these reasons, researchers have recently begun to use hypnosis with neurologically intact people in order to model clinical delusions. In this paper we describe striking analogies between the behavior of patients with a clinical delusion of mirrored self misidentification, and the behavior of highly hypnotizable subjects who receive a hypnotic suggestion to see a stranger when they look in the (...) mirror. Based on these analogies, we argue that the use of hypnosis is a reliable method to investigate the surface features of clinical delusions. But to what extent can hypnosis successfully recreate delusions? Can it also contribute to a better understanding of delusion formation? Although clinical delusions and hypnotically induced beliefs are different in etiology, some analogies can be identified in the underlying processes that characterise them, based on the two-factor theory of delusion formation.

Sensorimotor representations are essential for building up and maintaining corporeal awareness, i.e. the ability to perceive, know and evaluate one's own body as well as the bodies of others. The notion of embodied cognition implies that abstract forms of conceptual knowledge may be ultimately instantiated in such sensorimotor representations. In this sense, conceptual thinking should evoke, via mental simulation, some underlying sensorimotor events. In this review we discuss studies on the relation between embodiment and corporeal awareness. We approach the question (...) by issuing challenges from both ends. First, we ask whether bodily representations themselves can be disembodied or disconnected from underlying sensorimotor events. Second, we ask whether any concept, no matter how abstract, can actually be embodied in this way. The strong view of embodied cognition requires a negative answer to the first question, and an affirmative answer to the second. We also focus on the surprising range of cognitive processes that can be explained by linking them to corporeal awareness, such as aesthetic appreciation, and object constancy following brain damage. We conclude that (a) somatomotor simulation may help to understand the external world and the society of other individuals, but (b) some non-somatic forms of simulation may be required to explain how abstract knowledge contributes to understanding others' states. In this sense, the classic divide between sensorimotor and conceptual domains must remain in some form. (shrink)

This article combines the disciplines of textual/linguistic analysis, anthropology, and perceptual psychology to examine selected ancient Jewish mystical texts that claim to describe the praxis for ascents into heaven and encounters with angelic spirits in order to reconstruct the psychosocial context of these literary works. Specifically, the article examines Hekhalot or "Divine Palaces" texts that deal with hydromancy, giving attention to their mythic–symbolic assumptions, their described preparatory and triggering rituals, and their accounts of the ASC (altered states of consciousness) visions (...) resulting from these rituals that are experienced by the practitioners. The article suggests that these accounts correlate with ASC practices identified in the literature and additionally suggests that although the mystical texts are written to resemble biblical accounts of revelatory experiences, the texts under consideration are more than works of fabulous imagination; they are literary artifacts of an actual ecstatic ASC praxis among the Jews of Late Antiquity.

Botanical preparations used by shamans in rituals for divination, prophecy, and ecstasy contain widely different psychoactive compounds, which are incorrectly classified under a single denomination such as “hallucinogens,” “psychedelics,” or “entheogens.” Based on extensive ethnopharmacological search, I proposed a psychopharmacological classification of magic plants in 1979. This paper re-evaluates this taxonomy in the context of consciousness research. Several groups of psychodysleptic magic plants are proposed: (1) hallucinogens—psilocybin mushrooms, mescaline cacti, dimethyltryptamine snuffs, and the synthetic ergoline lysergic acid diethylamide induce strong (...) perceptual changes, affective intensification, and cognitive enhancement. Their ethnobotanical uses include long lasting divination rituals, prophecy, and sacramental practice. (2) Trance-inducers—ergoline Convolvulaceae and South American Banisteriopsis produce quietness, abstraction, lethargy, mild sensorial and cognitive changes, and salient visual imagery changes used in trance rituals and specific divination practices. (3) Cognodysleptics—marijuana (tetrahydrocannabinol) and other terpene-containing plants induce changes in thought, imagination, and affective functions and are used in short-term divination or oneiromancy. (4) Deliriants—tropane-containing Solanaceae, wild tobacco, and Amanita muscaria (muscimol) induce a delirium characterized by dim and clouded consciousness, stupor, confusion, disorientation, perception distortion, difficulties in recollection, anxiety, irritability, excitation, and behavioral disorganization employed in sorcery, purification, or exorcism rituals. The core mental effects required for a drug to be used in shamanistic rituals include light-headedness, enhanced imagery, and experience intensification. This constellation was the reason why, in his classification of psychoactive compounds, the pioneer German psychopharmacologist Louis Lewin established in 1924 a group of drugs under the appropriate name of Phantastica.

Virtually all experimental psychologists now accept that our behaviour can be affected by stimuli of which we have no conscious awareness. Such effects are typically not very dramatic even though they are reasonably reliable. However, such results do not on the surface appear to offer much support to claims of profound and lasting behavioural changes brought about by subliminal advertising or subliminal self-help tapes.

Research into the so-called “philosophical” Hermetica has long been dominated by the foundational scholarship of André-Jean Festugière, who strongly emphasized their Greek and philosophical elements. Since the late 1970s, this perspective has given way to a new and more complex one, due to the work of another French scholar, Jean-Pierre Mahé, who could profit from the discovery of new textual sources, and called much more attention to the Egyptian and religious dimensions of the hermetic writings. This article addresses the question (...) of how, on these foundations, we should evaluate and understand the frequent hermetic references to profound but wholly ineffable revelatory and salvational insights received during “ecstatic” states. Festugière dismissed them as “literary fictions”, whereas Mahé took them much more seriously as possibly reflecting ritual practices that took place in hermetic communities. Based upon close reading of three central texts (CH I, CH XIII, NH VI6), and challenging existing translations and interpretations, this article argues that the authors of the hermetic corpus assumed a sequential hierarchy of “levels of knowledge”, in which the highest and most profound knowledge (gnōsis) is attained only during ecstatic or “altered” states of consciousness that transcend rationality. While the hermetic teachings have often been described as unsystematic, inconsistent, incoherent or confused, in fact they are grounded in a precise and carefully formulated doctrine of how the hermetic initiate may move from the domain of mere rational discourse to the attainment of several “trans-rational” stages of direct experiential knowledge, and thereby from the limited and temporal domain of material reality to the unlimited and eternal one of Mind.

The processing, representation, and perception of bodily signals (interoception) plays an important role for human behavior. Theories of embodied cognition hold that higher cognitive processes operate on perceptual symbols and that concept use involves reactivations of the sensory-motor states that occur during experience with the world. Similarly, activation of interoceptive representations and meta-representations of bodily signals supporting interoceptive awareness are profoundly associated with emotional experience and cognitive functions. This article gives an overview over present findings and models on interoception and (...) mechanisms of embodiment and highlights its relevance for disorders that are suggested to represent a translation deficit of bodily states into subjective feelings and self-awareness.

It appears that consciousness science is progressing soundly, in particular in its search for the neural correlates of consciousness. There are two main approaches to this search, one is content-based (focusing on the contrast between conscious perception of, e.g., faces vs. houses), the other is state-based (focusing on overall conscious states, e.g., the contrast between dreamless sleep vs. the awake state). Methodological and conceptual considerations of a number of concrete studies show that both approaches are problematic: the content-based approach seems (...) to set aside crucial aspects of consciousness; and the state-based approach seems over-inclusive in a way that is hard to rectify without losing sight of the crucial conscious-unconscious contrast. Consequently, the search for the neural correlates of consciousness is in need of new experimental paradigms. (shrink)

In the formation of epistemically justified beliefs, what is the role of attention, and what is the role (if any) of non-attentional aspects of cognition? We will here argue that there is an essential role for certain nonattentional aspects. These involve epistemically relevant background information that is implicit in the standing structure of an epistemic agent’s cognitive architecture and that does not get explicitly represented during belief-forming cognitive processing. Since such “morphological content” (as we call it) does not become explicit (...) during belief formation, it cannot be information that is within the scope of attention. Nevertheless,it does exert a subtle influence on the character of conscious experience, rather than operating in a purely unconscious way. (shrink)

Not at all self-evident, the so-called isomorphisms between the phenomenology and physiology of dreams have been interpreted by Hobson et al. in an arbitrary manner to state that dreams are stimulated by chaotic brainstem stimulation (an assumption also adopted by Vertes & Eastman). I argue that this stimulation is not chaotic at all; nor does it occur in the absence of control from the cerebral cortex, which contributes complexity to brainstem activity as well as meaningful information worth consolidating in the (...) brain during sleep. [Hobson et al.; Vertes & Eastman]. (shrink)

Reinterpretation of our data concerning sleep onset, motivated by the desire to pay close attention to “intra-individual regularities,” suggests that the experience of control might be a key factor in determining the subjective sense that sleep has begun. This loss of control seems akin to what Frith and others have described as “passivity experiences,” which also occur in schizophrenia. Although clearly sleep onset is not a schizophrenic episode, this similarity might help to explain other features of sleep onset. We further (...) speculate that we could build upon the discovery of various “intra-individual regularities” to construct a model of sleep onset and other forms of sleep mentation. (shrink)

We review recent anticipatory looking and violation-of-expectancy studies suggesting that infants and young preschoolers have spontaneous (implicit) understanding of mind despite their known problems until later in life on elicited (explicit) tests of false-belief reasoning. Straightforwardly differentiating spontaneous and elicited expressions of complex mental state understanding in relation to an implicit-explicit knowledge framework may be challenging; early action predictions may be based on behavior rules that are complementary to the mentalistic attributions under consideration. We discuss that the way forward for (...) diagnosing early mentalism is to analyze whether young candidate mind-readers’ visual orienting cohere across different belief-formation by belief-use combinations. Adopting this formal cognitive analysis, we conclude that whilst some studies come tantalizingly close to sign-posting mentalism in infants and young children’s spontaneous responses, the bulk of evidence for early mentalism grades into behaviorism.

A new working hypothesis of sleep-wake cycle mechanisms is proposed, based on ontogeny and functional/anatomic compression of two stochastic neuronal models of information coding that complement each other in a key/lock fashion: the axonal arbor patterns (AAP – “hardware”) and the neuronal spike interval inequality patterns (SIIP – “software”).

Symbolic healing, that is, responding to meaningful experiences in positive ways, can facilitate human healing. This process partly engages consciousness and partly evades consciousness completely (sometimes it partakes of both simultaneously). This paper, presented as the Society for the Anthropology of Consciousness Distinguished Lecture at the 2011 AAA meeting in Montreal, reviews recent research on what is ordinarily (and unfortunately) called the “placebo effect.” The author makes the argument that language use should change, and the relevant portions of what is (...) often called the placebo effect should be referred to as the “meaning response.”.

The present review of literature surveys two main issues related to self-referential processes: (1) Where in the brain are these processes located, and do they correlate with brain areas uniquely specialized in self-processing? (2) What are the empirical and theoretical links between inner speech and self-awareness? Although initial neuroimaging attempts tended to favor a right hemispheric view of selfawareness, more recent work shows that the brain areas which support self-related processes are located in both hemispheres and are not uniquely activated (...) during self-reflective tasks. Furthermore, self-awareness at least partially relies on internal speech. An activation of Broca's area (which is known to sustain inner speech) is observed in a significant number of brain-imaging studies of self-reflection. Loss of inner speech following brain damage produces self-awareness deficits. Inner speech most likely can internally reproduce social mechanisms leading to self-awareness. Also, the process of self-reflection can be seen as being a problem-solving task, and self-talk as being a cognitive tool the individual uses to effectively work on the task. It is noted that although a large body of knowledge already exists on self-awareness, little is known about individual differences in dispositional self-focus and types of self-attention (e.g., rumination vs. self-reflection).

Altered states of consciousness (ASC), especially hallucinatory ones, are philosophically and scientifically interesting modes of operation of the mind–brain complex. However, classical definitions of ASC seem to capture only a few common characteristics of traditionally regarded phenomena, thus lacking exact classification criteria for assessing altered and baseline states. The current situation leads to a priority problem between phenomena-based definitions and definition-based phenomena selection. In order to solve the problem, this paper introduces a self-mapping procedure that is based on a three-part (...) analysis on certain aspects of hallucinatory altered consciousness. Starting with commonalities found in current definitions of ASC, issues with self-evaluation, sources of data, and baseline comparison are analyzed first. Next, the concept of alterations is examined with respect to temporal dynamics, change mechanisms, and mental subsystems. Finally, hallucinatory phenomena are discussed regarding various definitions, the relationship between “external” and “internal,” and the “trueness” issue of hallucinations. Conclusive to the analysis above, a technically based working definition of ASC and a stepwise operationalization procedure are also proposed. (shrink)

In the article, I propose that the body phantom is a phenomenal and functional model of one’s own body. This model has two aspects. On the one hand, it functions as a tacit sensory representation of the body that is at the same time related to the motor aspects of body functioning. On the other hand, it also has a phenomenal aspect as it constitutes the content of conscious bodily experience. This sort of tacit, functional and sensory model is related (...) to the spatial parameters of the physical body. In the article, I postulate that this functional model or map is of crucial importance to the felt ownership parameters of the body (de Vignemont 2007), which are themselves considered as constituting the phenomenal aspect of the aforementioned model.

States of being conscious (S) can be defined on the basis of temporal information processing. A high-frequency mechanism provides atemporal system states with periods of approximately 30 msec to implement the functional connection of distributed activities allowing the construction of primordial events; a low frequency mechanism characterized by automatic temporal integration sets up temporal windows with approximately 3 seconds duration. This integration mechanism can be used to define S. P-consciousness and A-consciousness as conceived of by Block can be mapped onto (...) these neuronal mechanisms. (shrink)

A number of philosophers have argued that psychiatric delusions threaten Donald Davidson's rationalist account of intentional agency. I argue that a careful look at both Davidson's account and psychiatric delusions shows that, in fact, the two are perfectly compatible. Indeed, a Davidsonian perspective on psychiatric delusions proves remarkably illuminating.

“Altered State of Consciousness” (ASC) has been defined as a changed overall pattern of conscious experience, or as the subjective feeling and explicit recognition that one's own subjective experience has changed. We argue that these traditional definitions fail to draw a clear line between altered and normal states of consciousness (NSC). We outline a new definition of ASC and argue that the proper way to understand the concept of ASC is to regard it as a representational notion: the alteration that (...) has happened is not an alteration of consciousness (or subjective experience) per se, but an alteration in the informational or representational relationships between consciousness and the world. An altered state of consciousness is defined as a state in which the neurocognitive background mechanisms of consciousness have an increased tendency to produce misrepresentations such as hallucinations, delusions, and memory distortions. Paradigm examples of such generally misrepresentational, temporary, and reversible states are dreaming, psychotic episodes, psychedelic drug experiences, some epileptic seizures, and hypnosis in highly hypnotizable subjects. The representational definition of ASC should be applied in the theoretical and empirical studies of ASCs to unify and clarify the conceptual basis of ASC research. (shrink)

This paper elaborates on the link between different types and degrees of experience that can be gone through within a form of life or collectivity—the so-called levels of immersion—and the development of distinct types of tacit knowledge and expertise. The framework is then probed empirically and theoretically. In the first case, its ‘predictions’ are compared with the accounts of novices who have gone through different ‘learning opportunities’ during a pre-operational training programme for running a huge nickel industrial plant in Brazil. (...) These are also analysed vis-à-vis the experience of an expert who has designed and experienced the outcomes of two pre-operational training sessions in the nickel industry before developing and managing the one discussed here. Theoretically, the framework is used to pinpoint exactly what interactional experts who have developed their expertise through linguistic socialisation alone are able to do as well as to analyse the case of technical connoisseurs. The results indicate that the proposed framework is useful. It supports the design and improvement of training programmes for the development of tacit knowledge while at the same time bringing about a refined analysis of claims concerning the abilities of types of experts and expertise.

Attention has been studied in cognitive psychology for more than half a century, but until recently it was largely neglected in philosophy. Now, philosophers of mind increasingly recognize that attention has an important role to play in our theories of consciousness and of cognition. At the same time, several recent developments in psychology have led psychologists to foundational questions about the nature of attention and its implementation in the brain. As a result there has been a convergence of interest in (...) fundamental questions about attention. This volume presents the latest thinking from the philosophers and psychologists who are working at the interface between these two disciplines. Its fourteen chapters contain detailed philosophical and scientific arguments about the nature and mechanisms of attention; the relationship between attention and consciousness; the role of attention in explaining reference, rational thought, and the control of action; the fundamental metaphysical status of attention, and the details of its implementation in the brain. These contributions combine ideas from phenomenology, neuroscience, cognitive psychology and philosophy of mind to further our understanding of this centrally important mental phenomenon, and to bring to light the foundational questions that any satisfactory theory of attention will need to address.

Humans are a part of the complex system including both natural and cultural-technological environment. Evolution of this system included self-amplifying feedbacks that lead to the appearance of human conscious mind. We describe the current state of the understanding of human brain evolution that stresses neurohormonal and biochemical changes rather than simple increase of anatomical substrate for the mind. It follows that human brain is strongly influenced by the state of the body and may operate at various levels of consciousness depending (...) on its biochemical environment created by ingestion of various substances and by specific physical activities. Through the study of the widespread phenomenon of shamanism that uses mind-altering practices we argue that altered states of consciousness and non-local minds are not only real phenomena, but that they are products of natural evolution, valuable for human survival and development. Consideration of altered states of consciousness and broadening of the framework for understanding brain function beyond mechanistic interpretations is necessary to further develop human adaptations and provide a better way of fitting humans as parts of the interconnected system into the global and universal patterns.

Conceptual congruency effects are biases induced by an irrelevant conceptual dimension of a task (e.g., location in vertical space) on the processing of another, relevant dimension (e.g., judging words’ emotional evaluation). Such effects are a central empirical pillar for recent views about how the mind/brain represents concepts. In the present paper, we show how attentional cueing (both exogenous and endogenous) to each conceptual dimension succeeds in modifying both the manifestation and the symmetry of the effect. The theoretical implications of this (...) finding are discussed. (shrink)

This article re-examines Ned Block‘s ( 1997 , 2007 ) conceptual distinction between phenomenal consciousness and access consciousness. His argument that we can have phenomenally conscious representations without being able to cognitively access them is criticized as not being supported by evidence. Instead, an alternative interpretation of the relevant empirical data is offered which leaves the link between phenomenology and accessibility intact. Moreover, it is shown that Block’s claim that phenomenology and accessibility have different neural substrates is highly problematic in (...) light of empirical evidence. Finally, his claim that there can be phenomenology without cognitive accessibility is at odds with his endorsement of the 'same-order-theory' of consciousness. (shrink)

Brain imaging has been immensely valuable in showing us how the mind works. However, many of our ideas about how the mind works come from disciplines like experimental psychology, artificial intelligence and linguistics, which in their modern form date back to the computer revolution of the 1940s, and are not strongly linked to the subdisciplines of biomedicine. Cognitive science and neuroscience thus have very separate intellectual roots, and very different styles. Unfortunately, these two areas of knowledge have not been well (...) integrated as far as higher mental processes are concerned. So how can these two be reconciled in order to develop a full understanding of the mind and brain? -/- This is the focus of this landmark book from leaders in the field. Coming more than two decades after Shallice's classic 'From neuropsychology to mental structure', 'The Organisation of Mind' establishes a strong historical, empirical, and theoretical basis for cognitive neuroscience. -/- The book starts by reviewing the history and intellectual roots of the field, looking at some of the researchers who guided and influenced it. The basic principles - theoretical and empirical and the inferential relation between them - are then considered with particular emphasis being placed on inferences to the organisation of the cognitive system from two empirical methodologies - neuropsychology and functional imaging. The core skeleton of the cognitive system is then analysed for the areas most critical for understanding rational thought. In the third section the components of simple cognitive acts are described, namely semantic processing, working memory, and cognitive operations. In the final section, more complex higher-level modulating processes are considered, including, supervisory processing, episodic memory, consciousness and problem-solving. -/- This will be a seminal publication on the interface between the brain sciences and the cognitive sciences and essential reading for all students and researchers in related fields.

In this paper, I discuss substance-induced visions and consider their epistemic status, meaning, and modes of proper interpretation. I focus on the visions induced by ayahuasca, a powerful psychoactive plant-made brew that has had a central status and role in the indigenous tribal cultures of the upper Amazonian region. The brew is especially famous for the visions seen with it. These are often coupled with personal psychological insights, mentations concerning topics of special significance to one, intellectual (notably, philosophical and metaphysical) (...) ideations, as well as powerful religious and spiritual sentiments. Thus, under the intoxication, people often feel that they gain significant knowledge and understanding. The present discussion takes a cognitive-phenomenological perspective coupled with a philosophical analysis of the various epistemological questions at hand. (shrink)

This study, which is based upon ethnographic data collected between 1999 and 2008 in Nepal, examines the connection between the shaman's altered states of consciousness (ASC; i.e., what goes on inside the healer's mind/brain) and therapeutic changes that take place in the patient's mind/body. Unlike other studies that primarily emphasize the shaman's internal psychological state, this article attempts to explain the role of the healer's ASC and elucidate how desired therapeutic changes depend upon patient–healer interactions.

Many organisms possess multiple sensory systems, such as vision, hearing, touch, smell, and taste. The possession of such multiple ways of sensing the world offers many benefits. These benefits arise not only because each modality can sense different aspects of the environment, but also because different senses can respond jointly to the same external object or event, thus enriching the overall experience - for example, looking at an individual while listening to them speak. However, combining information from different senses also (...) poses many challenges for the nervous system. -/- In recent years there has been dramatic progress in understanding how information from different sensory modalities gets integrated in order to construct useful representations of external space; and in how such multimodal representations constrain spatial attention.

Smith et al. present a model that they suggest may clarify aspects of the phylogenetic distribution of metacognition, based on observation of what they call uncertainty monitoring. Although they suggest that their model is supported by data collected using monkeys and dolphins, their interpretation that nonhuman animal behaviors parallel thought processes in humans may be unwarranted. The model presented by Smith et al. is inconsistent with current theories and empirical findings on the comparative aspects of metacognition. We present three oversights (...) of the model and extend our critique to include a brief discussion of animal self-awareness, as well as current neuropsychological perspectives on metacognitive processing in humans.

Recent work on functional brain architecture during dreaming provides invaluable clues for an understanding of dreaming, but identifying active brain regions during dreaming, together with their waking cognitive and cognitive functions, informs a model that accounts for only the grossest characteristics of dreaming. Improved dreaming models require cross discipline apprehension of what it is we want dreaming models to “explain.” [Hobson et al.; Neilsen; Revonsuo; Solms].

What could it mean to be conscious in your dreams? For most of us, dreaming is something quite separate from normal life. When we wake up from being chased by a ferocious tiger, or seduced by a devastatingly good-looking Nobel Prize winner we realize with relief or disappointment that "it was only a dream.".

There are obvious flaws in REM sleep suppression paradigms that do not allow any conclusion to be drawn either pro or contra the REM sleep-memory hypothesis. However, less intrusive investigations of REM sleep suggest that this sleep stage or its adjunct neuroendocrine characteristics exert a facilitating influence on certain aspects of ongoing memory formation during sleep.

What is the role of conscious perceptual experience in the acquisition of empirical knowledge? My central claim is that a proper account of the way in which perceptual experiences contribute to our understanding of the most basic beliefs about particular things in the mind-independent world around us reveals how such experiences provide peculiarly fundamental reasons for such beliefs. There are, I claim, epistemic requirements upon the very possibility of empirical belief. The crucial epistemological role of experiences lies in their essential (...) contribution to the subject’s understanding of certain perceptual demonstrative contents, simply grasping which provides him with a reason to endorse them in belief.

"Dreams" is a long overdue collection of writing on dreams from many of the top scholars in religious studies, anthropology, and psychology departments.

Two aspects of consciousness are first considered: consciousness as awareness (phenomenological meaning) and consciousness as strategic control (functional meaning). As to awareness, three types can be distinguished: first, awareness as the phenomenal experiences of objects and events; second, awareness as meta-awareness, i.e., the awareness of mental life itself; third, awareness as self-awareness, i.e., the awareness of being oneself. While phenomenal experience and self-awareness are usually present during dreaming (even if many modifications are possible), meta-awareness is usually absent (apart from some (...) particular experiences of self-reflectiveness) with the major exception of lucid dreaming. Consciousness as strategic control may also be present in dreams. The functioning of consciousness is then analyzed, following a cognitive model of dream production. In such a model, the dream is supposed to be the product of the interaction of three components: (a) the bottom-up activation of mnemonic elements coming from LTM systems, (b) interpretative and elaborative top-down processes, and (c) monitoring of phenomenal experience. A feedback circulation is activated among the components, where the top-down interpretative organization and the conscious monitoring of the oneiric scene elicitates other mnemonic contents, according to the requirements of the dream plot. This dream productive activity is submitted to unconscious and conscious processes. (shrink)
