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...
: Sleep researchers in different disciplines disagree about how fully dreaming can be explained in terms of brain physiology. Debate has focused on whether REM sleep dreaming is qualitatively different from nonREM (NREM) sleep and waking. A review of psychophysiological studies shows clear quantitative differences between REM and NREM mentation and between REM and waking mentation. Recent...
This study tested the two main neurocognitive models of dreaming by using cognitive data elicited from REM sleep in normals and narcoleptics. The two models were the "activation-only" view which holds that, in the context of sleep, overall activation of the brain is sufficient for consciousness to proceed in the manner of dreaming (e.g., Antrobus, 1991; Foulkes, 1993; Vogel, 1978); and the...
The formal features of dream characters were studied in a sample of 320 dream reports submitted by 33 adult subjects (13 male, 20 female) of varying ages in a university extension course. Subjects were queried by questionnaire about dream characters immediately after recording their dreams upon awakening in their normal home setting. It was found that 48% of characters represented a named...
The five authors vary in the degree to which the recent neuroscience of the REM state leads them towards multiple dimensions and forms of dreaming consciousness (Hobson et al.; Nielsen; Solms) or toward all-explanatory single factor models (Vertes & Eastman, Revonsuo). The view of the REM state as a prolongation of the orientation response to novelty fits best with the former pluralisms but not...
The concept of transliminality ("a hypothesized tendency for psychological material to cross thresholds into or out of consciousness") was anticipated by William James (1902/1982), but it was only recently given an empirical definition by Thalbourne in terms of a 29-item Transliminality Scale. This article presents the 17-item Revised Transliminality Scale (or RTS) that corrects age and gender...
People can remember the content of a dream in rapid eye movement (REM) sleep but cannot do so in slow-wave sleep. According to a brain model, memory is stored in encoding synapses as presynaptic axonal 'on-off' patterns and modulating synapses help encoding synapses convert short-term memory into long-term memory. These lead to the hypothesis that REM sleep involves modulating synapses of the...
Fifteen Central Australian Aboriginal adults (8 patients, 7 colleagues) were presented with a culturally modified version of Flavell's 'stream of consciousness' experiment (pictures of persons with empty or 'busy' thought-bubbles, and an invitation to assign a picture to the mental state of a second experimenter seen reading or sitting quietly). Only 4 people assigned the empty thought bubble...
Article States Of Consciousness in Sleep, Dream and Beyond: A Biothermodynamic and Neurocybernetic Evolutionary Study was published on February 1, 2000 in the journal Journal of Intelligent Systems (volume 10, issue 1).
It is widely supposed in the scientific and popular literature on dreams that flying in dreams is of mostly delightful character. Domhoff (1996) recently emphasised the highly positive feelings experienced in flying dreams although he mentions a turn to apprehension later in the dream ("crashing", "coming down"). In my research (an interview-sample of flying dreams) I met flying experiences in...
