Abstract: Many astrologers attribute a successful birth-chart reading to what they call intuition or psychic ability,where the birth chart acts like a crystal ball. As in shamanism,they relate consciousness to a transcendent reality that,if true, might require are-assessment of present biological theories of consciousness.In Western countries roughly 1 person in 10,000 is practising or seriously studying astrology, so their total number is substantial. Many tests of astrologers have been made since the 1950s but only recently has a coherent review been (...) possible. A large-scale test of persons born less than five minutes apart found no hint of the similarities predicted by astrology. Meta-analysis of more than forty controlled studies suggests that astrologers are unable to perform significantly better than chance even on the more basic tasks such as predicting extraversion. More specifically,astrologers who claim to use psychic ability perform no better than those who do not. The possibility that astrology might be relevant to consciousness and psi is not denied, but such influences, if they exist in astrology,would seem to be very weak or very rare. -/- . (shrink)

Alfred North Whitehead famously compares the philosophical method of knowledge acquisition with the process of flying an airplane. Likewise, “shamanic flight” marks stages of cognitive processing in navigation through perceptible and imperceptible worlds. This article focuses on the cosmovision of the Amazon people Huni Kuin, the Whiteheadian method of imaginative rationalization, and the concept of Amerindian perspectivism. This study also investigates shamanism as an experience of knowledge generation. Furthermore, “shamanic flight,” as an ecstatic technique experienced in many diverse Amerindian rituals, (...) will be explored as a method in the discovery and organization of nonhuman alterities. Finally, Amazonian-based shamanic epistemology will be discussed within a “multinaturalist” ontology. (shrink)

Psychedelics have been recognized as model interventions for studying altered states of consciousness. However, few empirical studies of the shamanic state of consciousness, which is anecdotally similar to the psychedelic state, exist. We investigated the neural correlates of shamanic trance using high-density electroencephalography (EEG) in 24 shamanic practitioners and 24 healthy controls during rest, shamanic drumming, and classical music listening, followed by an assessment of altered states of consciousness. EEG data were used to assess changes in absolute power, connectivity, signal (...) diversity, and criticality, which were correlated with assessment measures. We also compared assessment scores to those of individuals in a previous study under the influence of psychedelics. Shamanic practitioners were significantly different from controls in several domains of altered states of consciousness, with scores comparable to or exceeding that of healthy volunteers under the influence of psychedelics. Practitioners also displayed increased gamma power during drumming that positively correlated with elementary visual alterations. Furthermore, shamanic practitioners had decreased low alpha and increased low beta connectivity during drumming and classical music and decreased neural signal diversity in the gamma band during drumming that inversely correlated with insightfulness. Finally, criticality in practitioners was increased during drumming in the low and high beta and gamma bands, with increases in the low beta band correlating with complex imagery and elementary visual alterations. These findings suggest that psychedelic drug-induced and non-pharmacologic alterations in consciousness have overlapping phenomenal traits but are distinct states of consciousness, as reflected by the unique brain-related changes during shamanic trance compared to previous literature investigating the psychedelic state.

This paper presents the story of an isiXhosa traditional healer, Nomzi Hlathi, as told to the first author. Nomzi was asked about how she came to be an igqirha and the narrative focuses on those aspects of her life story that she understood as relevant to that developmental process. The material was obtained from a series of semi-structured interviews with Nomzi, with some collateral from her cousin, and synthesised into a chronological narrative presented in Nomzi’s own words. The aim of (...) the study was to examine her account of her unfolding experience within three hermeneutic frames. The first is the isiXhosa traditional account of what it is to become an igqirha, a process initiated by intwaso, an illness understood to be a call from the ancestors, and guided by messages from the ancestors in dreams and other symbolic communications. The second is the perspective of Western Clinical Psychology on the cognitive, emotional and behavioural disturbances that characterise intwaso. The third is the perspective of transpersonal psychology on the nature and development of shamanic healing gifts, as understood from observations of such practices in traditional societies across the world. As the narrative of Nomzi’s story is quite long, this paper presents her narrative as well as the methodology which gave rise to it. The interpretative review of the material from each of the three perspectives is presented in a second paper. (shrink)

Properties of mental representation are related to findings in cognitive science and ideas in shamanism. A selective review of research in cognitive science suggests visual images and spatial memory preserve important functional information regarding physical principles and the behavior of objects in the natural world, and notions of second‐order isomorphism and the perceptual cycle developed to account for such findings are related to shamanic experience. Possible roles of implicit processes in shamanic cognition, and the idea that shamanic experience may involve (...) normally unconscious information becoming temporarily available to consciousness, are considered. The existence of a cognitive module dedicated to processing information relevant to social knowledge and social interaction is consistent with cognitive science and with shamanism, and may help account for the extension of intentionality and meaning that characterize shamanic practice. Overall, findings from cognitive science and ideas from shamanism exhibit a number of correspondences and similarities regarding basic properties of cognition, and this suggests that shamanic and nonshamanic cognition may not be fundamentally different.

Attempts to elucidate the kinds of “thing” or “things” to which the term shamanic journeying image is referentially linked must grapple with two related questions: what is the fundamental nature of shamanic journeying images, and how might the origin of a shamanic journeying image be found? The first question is ontological, concerned with the nature and essence of shamanic journeying images. In contrast, the second is epistemological and methodolgical, concerned with how to acquire knowledge of shamanic journeying images. We demonstrate (...) how inductive and deductive reasoning, the private language argument, and reification render problematic the resolution of both. Finally, we present a method to preliminarily formulate an ontology and epistemology of shamanic journeying imagery. (shrink)

In this paper, it is argued that “higher states of consciousness”–or mystical experiences–have two main sources: they can be caused by a disruption of the normal homeostasis of the human organism and also by an intensification of the “consciousness-energy” that constitutes our being. . The author investigates examples of both types of experience, and compares and contrasts them. It is concluded that the second type of experience is the only one which is truly positive and which can become a fully (...) integrated and permanent higher state of consciousness. (shrink)

Correspondences and similarities between ideas in shamanism and ideas in contemporary cognitive science are considered. The importance of interconnectedness in the web of life worldview characteristic of shamanism and in connectionist models of semantic memory in cognitive science, and the extension of meaning to elements of the natural world in shamanism and indistributed cognition, are considered. Cognitive consequences of such an extension (e.g., use of representativeness and intentional stance heuristics, magical thinking, social attribution errors, and social in‐group/out‐group differences) are discussed. (...) It is suggested that attributions of mental states, beliefs, and desires to a computer on the basis of behavioral measures (e.g., the Turing test) is consistent with the extension of meaning and intentionality to nonhuman elements of the natural world in shamanism. In general, the existence of such correspondencesand similarities suggests that elements of shamanism may reflect cognitive structures and processes that are also used by nonshamans and in nonshamanic settings.

Shamans of the Piaroa ethnic group (southern Venezuela) conceive of power in terms of knowledge derived from visionary experiences. Märipa is an epistemology concerning the translation of knowledge derived from the integrative mode of consciousness, induced primarily through the consumption of plant hallucinogens, to practical effect during waking life. I integrate mythological, neurobiological, experiential, and ethnographic data to demonstrate what märipa is, and how it functions. The theory and method of märipa underlie not only Piaroa shamanic activity, but all aspects (...) of Piaroa life; mythology, causality, eschatology, and history. Piaroa shamanic practices involve conditioning the mind to achieve optimal perceptual capacities that facilitate accurate prediction and successful psycho‐social prescription. Piaroa shamans describe their technologies of consciousness in terms of gods and spirits, but also in terms of studying and the acquisition of information. Because neurobiological processes underlie the development and experience of märipa, the language of neurobiology enables a partial translation of this indigenous epistemology. The concepts of feed forward neural processing and somatic markers are central to the processes of mental imagery cultivation that Piaroa shamans employ to divine solutions to adaptive problems. Piaroa 'techniques of ecstasy' involve the ability to apply mythological templates of human adaptation to schemas of human behaviour based on years of social analysis in association with heightened information processing capacities derivative of refined experimentation with the integrative mode of consciousness.

Discussions about consciousness are complicated by the fact that participants do not share a common underlying “ordinary” consciousness. Everyday experience is founded on what Teasdale calls implicational cognition, much of which is not verbally formulated. An unacknowledged aspect of debate is individuals’ attempts to negotiate the expression of their unformulated experience. This is further complicated by the way in which a discourse, based on particular ontological assumptions, exercises an ideological control which limits what underlying aspects of experience can be formulated (...) at all. Tart’s concept of state specific sciences provides a framework within which the role of unformulated experience can be acknowledged and taken into account. Unless this is done, debates will be vitiated by participants engaging in ideological struggles and talking at cross-purposes. (shrink)

Causal representation in shamanic consciousness is compared with causal representation in ordinary waking consciousness. Causal representation in shamanic experience and in ordinary waking experience can engage strategies involving attribution of intentionality , heuristics , and magical thinking . Such strategies have consequences involving social biases , locus of control, authorship of actions, and supernaturalizing of social life. Similarities of causal representation in shamanic experience and in ordinary waking experience have implications for theories of mind and theories of causal representation, and (...) these implications involve use of metaphor and analogy, modular processing of social information, use of behavioural criteria for mental states, differences between physical causality and social causality, property transmission in causal representation, and whether causal representation involves general or state-specific processes. Principles of causal representation in shamanic consciousness appear consistent with principles of causal representation in ordinary waking consciousness. (shrink)
