The emergence of consciousness: BUC versus SOC

Behavioral and Brain Sciences June 1, 2002 Ron Sun

This commentary suggests that there are two distinct types of interacting cognitive processes. Conscious processes emerge from unconscious processes. The key problem of SOC is that it uses an overly narrow notion of the “cognitive unconscious” to show that the “cognitive unconscious” is not necessary. Yet, it has little to say about the roles of conscious and unconscious processes in general.

The neurophysics of consciousness.

Brain research. Brain research reviews June 2002 E Roy John

Consciousness combines information about attributes of the present multimodal sensory environment with relevant elements of the past. Information from each modality is continuously fractionated into distinct features, processed locally by different brain regions relatively specialized for extracting these disparate components and globally by interactions among these regions. Information is...

Science as if situation mattered

June 1, 2002 M. Bitbol

When he formulated the program of neurophenomenology, Francisco Varela suggested a balanced methodological dissolution of the “hard problem” of consciousness. I show that his dissolution is a paradigm which imposes itself onto seemingly opposite views, including materialist approaches. I also point out that Varela's revolutionary epistemological ideas are gaining wider acceptance as a side...

Three days for weeping: dreams, emotions, and death in the Peruvian Amazon.

Medical Anthropology Quarterly June 1, 2002 Glenn H. Shepard

Funeral customs and beliefs about the dead among the Matsigenka of Peru reflect great anxiety over the contagion of death and the power of the dead over the living. In this article, these beliefs and practices are interpreted in light of a native theory about emotion. For the Matsigenka, excessive displays of emotion, especially grief, anger, and aggressive sexuality, cause a vicious cycle of...

Prospects for the Scientific Study of Phenomenal Consciousness

Thinking about Consciousness April 25, 2002 David Papineau

Abstract Many scientists hope that brain research will identify the material nature of conscious states. Papineau argues that when it comes to the “hard problem” of identifying the material referents of phenomenal concepts, scientific research can only take us so far. This is because phenomenal concepts are vague and do not point determinately to specific material states. This chapter also...

Consciousness Evolving

Advances in Consciousness Research April 8, 2002

A collection of stimulating studies on the past, the present, and the future of consciousness, Consciousness Evolving contributes to understanding some of the most important conceptual problems of our time. The advent of the modern synthesis together with the human genome project affords a platform for considering what it is that makes humans distinctive. Beginning with an essay that accents...

Consciousness and the varieties of emotion experience: a theoretical framework.

Psychology Review April 1, 2002 J. Lambie, A. Marcel

Data reviewed suggest that previous theories of emotion experience are too narrow in scope and that lack of consensus is due to the fact that emotion experience takes various forms and is heterogenous. The authors treat separately the content of emotion experience, the underlying nonconscious correspondences, and processes producing emotion experience. They classify the nature and content of...

Increased dopamine tone during meditation-induced change of consciousness.

Brain research. Cognitive brain research April 2002 Troels W Kjaer, Camilla Bertelsen, Paola Piccini et al.

This is the first in vivo demonstration of an association between endogenous neurotransmitter release and conscious experience. Using 11C-raclopride PET we demonstrated increased endogenous dopamine release in the ventral striatum during Yoga Nidra meditation. Yoga Nidra is characterized by a depressed level of desire for action, associated with decreased blood flow in prefrontal, cerebellar...

Altered states of consciousness: review of experimental data obtained with a multiple techniques approach.

The Journal of Alternative and Complementary Medicine April 2002 Pavel V Bundzen, Konstantin Korotkov, Lars-Erick Unestahl

To investigate the psychophysiologic mechanisms of an altered state of consciousness (ASC) produced via systematic mental training by correlating the results of multiple computerized bioelectrographic measurements. All subjects were tested, using a set of modern computerized techniques comprising digital electroencephalography, measurement of the low-frequency bilateral activity of the brain,...
