Magnetic correlates in electromagnetic consciousness

ABSTRACT

We examine the hypothesis that consciousness is a manifestation of the electromagnetic field, finding supportive factors not previously considered. It is not likely that traditional electrophysiological signaling modes can be readily transmitted throughout the brain to properly enable this field because of electric field screening arising from the ubiquitous distribution of high dielectric lipid membranes, a problem that vanishes for low-frequency magnetic fields. Many reports over the last few decades have provided evidence that living tissue is robustly sensitive to ultrasmall (1–100 nT) ELF magnetic fields overlapping the γ-frequency range often associated with awareness. An example taken from animal behavior (coherent bird flocking) lends support to the possibility of a disembodied electromagnetic consciousness. In contrast to quantum consciousness hypotheses, the present approach is open to experimental trial.     

Bringing class back in: class consciousness and solidarity among Chinese migrant workers in Italy and the UK

The growing literature on international migration has a tendency to emphasize homogenous elements such as shared ethnic background, social network and cultural similarities in shaping immigrants' identity. We argue that this underestimates the differences (and sometimes conflicts) of interests between ethnic employers and migrant workers and that class needs to be brought back into the studies of ethnic relationship. Based upon findings from a series of fieldwork in Veneto, Italy and East Midlands, UK, this article contends that class consciousness has co-existed, sometimes uneasily, alongside co-ethnic and cultural relationships among Chinese migrant workers and has played an important part in the making of new Chinese communities. By analysing the perspectives of Chinese migrant workers and their relationship with co-ethnic entrepreneurs, this article illustrates complex factors behind the formation, diffusion and development of class consciousness among Chinese migrant workers.     

A model of subjective report and objective discrimination as categorical decisions in a vast representational space

Subliminal perception studies have shown that one can objectively discriminate a stimulus without subjectively perceiving it. We show how a minimalist framework based on Signal Detection Theory and Bayesian inference can account for this dissociation, by describing subjective and objective tasks with similar decision-theoretic mechanisms. Each of these tasks relies on distinct response classes, and therefore distinct priors and decision boundaries. As a result, they may reach different conclusions. By formalizing, within the same framework, forced-choice discrimination responses, subjective visibility reports and confidence ratings, we show that this decision model suffices to account for several classical characteristics of conscious and unconscious perception. Furthermore, the model provides a set of original predictions on the nonlinear profiles of discrimination performance obtained at various levels of visibility. We successfully test one such prediction in a novel experiment: when varying continuously the degree of perceptual ambiguity between two visual symbols presented at perceptual threshold, identification performance varies quasi-linearly when the stimulus is unseen and in an ‘all-or-none’ manner when it is seen. The present model highlights how conscious and non-conscious decisions may correspond to distinct categorizations of the same stimulus encoded by a high-dimensional neuronal population vector.     

Psychophysiological correlates of lucid dreaming.

The main goal of the present study was to explore electrophysiological differences between lucid and nonlucid dreams in REM sleep. Seven men and four women experienced in lucid dreaming underwent polysomnographic recordings in the sleep laboratory on two consecutive nights. EEG signals were subjected to spectral analysis to obtain five different frequency bands between 1 and 20 Hz. Lucidity was determined by both subjective dream reports and eye-movement signals made by the subjects in response to light stimuli indicating a REM period. The main discrimination factor between lucid and nonlucid dreaming was found in the beta-1 frequency band (13-19 Hz), which in lucid dreaming was increased in both parietal regions. The ratio of frontal to parietal beta-1 activity was 1 to 1.16 in nonlucid and 1 to 1.77 in lucid dreaming. A tendency towards the greatest increase was observed in the left parietal lobe (P3), an area of the brain considered to be related to semantic understanding and self-awareness.

Cognitive differences in dream content and boundary structure between Asian and Pacific Islander Americans and European Americans using quantitative content analysis.

Cognitive differences in boundary thickness and dream content were investigated in Asian and Pacific Islander American and European American undergraduates (N=30). Participants completed Hartmann's Boundary Questionnaire and kept dream journals for 4 weeks. Eleven dream reports per participant (330 total dream reports) were scored using Hall-Van de Castle's System of Content Analysis and the Bizarreness Scoring System. The Asian and Pacific Islander Americans scored thicker than the European Americans on the Boundary Questionnaire. They also showed trends toward shorter dream reports that were more dense (i.e., increased dream elements per dream length), with less fragility. Differences in dream bizarreness and verbs were nonsignificant, but did yield medium effect sizes. These results are discussed in terms of underlying cultural and cognitive differences.

Results of human evolution research in Czechoslovakia

The results of anthropological research into human evolution have been discussed. Only two research places in CSSR have been engaged with the human evolution: the Department Anthropos in the Moravian Museum in Brno and the Laboratory of Evolutionary Biology of the Czechoslovak Academy of Sciences in Praha. The first of them has been mainly concerned with the paleontological and archeological research reported elsewhere. In the second, the following main questions of human evolution have been discussed: the evolution of bipedal locomotion, the morphological aspects, both qualitative and quantitative ones, the locomotion in other primates and various aspects of their behaviour have been studied. In this connection also various questions of the evolution the of human mind and social consciousness were studied. Special attention has been paid to role of neoteny in the evolution of man and to the import of synergism of the main evolutionary factors. As one of the main results is the principle of sociogenesis viewed and its various aspects. Its top product is human consciousness integrating the most important results of human thinking. Much attention has been paid to its evolution on the basis of the principle of reflection. Also the philosophical and ideological consequences of the sociogenesis as the main trend in the evolution of organisms have been elaborated in detail.     

Video game play and dream bizarreness.

In a series of studies, J. Gackenbach has been mapping the effects of heavy video game play on consciousness, including dreaming. The reason that gamers are being investigated is that they represent a group of people who are engaging in the most immersive media experience widely available today. With its audio and visual interactive nature as well as the long hours often required to master a game, they are an opportune group to study media effects upon consciousness. In this study, the focus was on dream bizarreness. Dream bizarreness has been variously thought to be the differentiator between waking and dreaming thought, an indication of creativity, and most recently, as a model for solving the binding problem in consciousness. Using A. Revonsuo’s and C. Salmivalli’s scale for dream content analysis, it was found that high-end gamers evidenced more bizarre dreams than did low-end gamers in two of three types of bizarreness categories.

The actual conditions of practising traditional methods of environmental control and utilization of air conditioners by the residents of detached houses in kyoto during summer

1. 1. Reducing the carbon dioxide generated by human activity is necessary for the protection of the global environment.

2. 2. Traditional methods of environmental control, e.g. watering, called uchimizu in Japan, is interesting from this point of view. Traditional methods, other than watering, still continue to be practised in Japan.

3. 3. More than 300 residents of detached houses in Kyoto city were investigated for the methods of environmental control used in summer. Investigated areas were Kitashirakawa, Nishijin and Rakusai N.T.

4. 4. Residents' who conduct traditional methods of environmental control use air conditioner (ACs) less than those who don't. Residents' attitude toward ACs have a greater effect on total time of use rather than on frequency.

5. 5. In the centre of the city, there is a tendency for residents to use ACs against their will or only as a necessity, which leads to anxiety regarding their health.

6. 6. The use of traditional methods of protection from heat have been decreasing with social change.
