Quantum Approaches to Consciousness plato.stanford.edu Nov 30, 2004 24 facts
claimThe author of the entry 'Quantum Approaches to Consciousness' received comments from Guido Bacciagaluppi, Friedrich Beck, Thomas Filk, Stuart Hameroff, Hans Primas, Henry Stapp, and an anonymous referee that improved an earlier version of the manuscript.
claimHenry Stapp (1999) asserts that every conscious experience has a physical counterpart consisting of a quantum state reduction that actualizes the pattern of activity known as the neural correlate of that conscious experience.
perspectiveHenry Stapp has developed a perspective since the 1980s that attempts to relate specific features of consciousness to quantum theory by locating the interface between the observed and observing system within the observer's brain.
referenceHenry P. Stapp authored the 2007 book 'Mindful Universe', published in Berlin by Springer.
quoteHenry Stapp (1993) proposes attaching an 'experiential aspect' or 'feel' to each Heisenberg actual event, which grants the event its status as an intrinsic actuality.
claimIn the neurophysiological implementation of Henry Stapp's theory, intentional mental states are assumed to correspond to the reduction of superposition states within neuronal assemblies.
claimIn a 2006 interview, Henry Stapp specified that in his approach, which draws on Alfred North Whitehead's process thinking, 'actual occasions' are the fundamental elements of reality rather than matter or mind.
claimHenry Stapp (2006, 2007) proposes that mind-matter correlations act as a constraint on how outcomes are formed within an actual occasion, replacing the traditional notion of interaction.
perspectiveHenry Stapp's conception of consciousness is conservative regarding physical formalism but radical in its assertion that quantum measurement involves a conscious act in addition to a physical process.
referenceThe approach initiated by John von Neumann in the 1930s, later developed by Eugene Wigner, and currently championed by Henry Stapp, proposes that intentional conscious acts are intrinsically correlated with physical state reductions.
claimThe author of the entry 'Quantum Approaches to Consciousness' acknowledges discussions with Guido Bacciagaluppi, Thomas Filk, Hans Flohr, Hans Primas, Stefan Rotter, Henry Stapp, Giuseppe Vitiello, and Max Velmans.
claimIn Henry Stapp's model of consciousness, the neural correlate of a conscious experience can encode an intention, functioning as a 'template for action' that serves as the basis for free will.
claimIn Henry Stapp's theory, each actualized event contains the tendency for the subsequent actualization of another event, making events inherently ambiguous.
claimHenry Stapp's quantum consciousness theory does not suggest modifications to present-day quantum theory, specifically remaining within the orthodox Hilbert space representation, but adds interpretational extensions regarding a detailed ontological framework.
referenceHenry P. Stapp authored the 2006 paper 'Clarifications and Specifications In Conversation with Harald Atmanspacher', published in the Journal of Consciousness Studies, volume 13, issue 9, pages 67–85.
claimHenry Stapp's 1993 work builds on Werner Heisenberg's 1958 distinction between the potential and the actual to move beyond the operational Copenhagen interpretation of quantum mechanics.
referenceHenry P. Stapp authored the 1999 paper 'Attention, intention, and will in quantum physics', published in the Journal of Consciousness Studies, volume 6, issue 8/9, pages 143–164.
referenceThe article 'Quantum Approaches to Consciousness' surveys several quantum-based theories of consciousness, including those proposed by Henry Stapp, Umezawa and Vitiello, Beck and Eccles, Penrose and Hameroff, dual-aspect approaches (Pauli, Jung, Bohm, Hiley), and models characterizing mental features using quantum formal structures (Aerts and colleagues).
claimHenry Stapp's approach suggests an expanded ontological basis for both the mental domain and status-quo quantum theory as a theory of matter without essentially changing the formalism of quantum theory, though it lacks empirical confirmation.
claimHenry Stapp (1999) describes a 'hybrid ontology' that includes both idea-like and matter-like qualities and two complementary modes of evolution.
claimHenry Stapp argues that mental effort, specifically attention directed toward intentional acts, can extend the lifetime of the neuronal assemblies representing templates for action through quantum Zeno-type effects.
claimHenry Stapp relates the processual nature of actual occasions to both the physical act of quantum state reduction and the correlated psychological intentional act.
claimThe quantum approaches to consciousness proposed by Henry Stapp and Giuseppe Vitiello contain elements of dual-aspect thinking, although the authors do not emphasize this aspect.
quoteHenry Stapp (1999) proposes that conscious intentions of a human being can influence the activities of the human brain.
Quantum Approaches to Consciousness plato.stanford.edu Nov 30, 2004 17 facts
claimHenry Stapp proposes a 'hybrid ontology' that includes both idea-like and matter-like qualities, which relates to Whitehead’s ontology where mental and physical poles of 'actual occasions' are considered psychological and physical aspects of reality.
claimHenry Stapp locates the interface between the observed and observing system within the observer’s brain, inspired by von Neumann’s work.
perspectiveHenry Stapp does not suggest formal modifications to present-day quantum theory, maintaining the orthodox Hilbert space representation, but adds interpretational extensions regarding an ontological framework.
quoteHenry Stapp (2015) describes quantum events as 'not actually random but positively or negatively biased by the positive or negative values in the minds of the observers that are actualized by its (nature’s) choices.'
claimHenry Stapp describes the relationship between mental and material outcomes as a constraint set by mind-matter correlations, rather than a direct interaction.
claimHenry Stapp (2015) proposes a 'semi-orthodox' approach to quantum mechanics where the randomness of individual quantum events is reconceived as being biased by the positive or negative values in the minds of observers.
claimHenry Stapp maintains that his approach to consciousness does not change the orthodox quantum mechanics encoded in the statistical formulation by John von Neumann.
claimHenry Stapp posits that a pattern of neural activity may encode an intention and represent a template for action, which serves as the basis for free will.
claimIn a 2006 interview, Henry Stapp specified that his ontological approach is based on Whitehead’s process thinking, where 'actual occasions' rather than matter or mind are the fundamental elements of reality.
claimIn his 1993 work, Henry Stapp utilized Heisenberg’s distinction between the potential and the actual to move beyond the operational Copenhagen interpretation of quantum mechanics.

Moving Forward on the Problem of Consciousness - David Chalmers consc.net 14 facts
claimHenry Stapp proposes a theory of consciousness that treats consciousness as a given entity that plays a role in collapsing physical wave functions, thereby impacting the physical world.
perspectiveDavid Chalmers considers Henry Stapp's theory to be perhaps the most sophisticated version of a 'collapse' interpretation of quantum mechanics to date, as it provides a natural picture of consciousness influencing a non-causally-closed physical world.
claimDavid Chalmers observes that Henry Stapp's proposal regarding the causal role of consciousness is compatible with many different psychophysical theories.
claimDavid Hodgson and Henry Stapp appeal to quantum mechanics as a potential reason to deny the causal closure of the physical world.
claimTheories involving Cartesian ectoplasm, Benjamin Libet's 'conscious mental field', and the views advocated by Henry Stapp and David Hodgson are all subject to the same epiphenomenalist worry as John Eccles' psychon theory, where the experiential quality of the mental states is inessential to the causal explanation of behavior.
claimDavid Chalmers notes that if Henry Stapp's proposal were accepted, experimental physics could theoretically help determine psychophysical laws and identify which systems are conscious by testing for the presence or absence of physical collapse.
perspectiveDavid Chalmers notes that Henry Stapp's theory is neutral on physical-to-mental laws, which are necessary to determine which physical processes are associated with consciousness and what specific conscious experience corresponds to a given physical process.
referenceHenry Stapp proposes in his 1993 book that conscious experience is associated with 'top-level processes' in the brain.
claimDavid Chalmers argues that Henry Stapp's own theory is susceptible to a 'quantum zombie' objection, where a world exists where physical states cause collapse directly without consciousness, yet all functions are performed the same.
claimDavid Chalmers argues that Henry Stapp's theory of consciousness does not clearly give experience an essential role because a theory could be formulated that invokes states causing collapses without mentioning experience at all.
claimHenry Stapp uses the 'zombie' possibility in classical physics to argue that if physics is causally closed, physically identical zombies with the same behavior are logically possible, which suggests experience plays no essential role in behavior.
claimWhile many proposals for a fundamental theory of consciousness invoke panpsychism, David Chalmers notes that Benjamin Libet and Henry Stapp have proposed fundamental theories of consciousness that do not rely on panpsychism.

claimHenry Stapp replaces the notion of direct interaction between mind and matter with the notion of a constraint set by mind-matter correlations.
claimHenry Stapp and the team of Friedrich Beck and John Eccles propose that the ontic randomness of quantum events provides a mechanism for mental causation, allowing conscious mental acts to influence brain activity.
claimHenry Stapp posits that the mental and material outcomes of an actual occasion must be correlated, which acts as a constraint on how these outcomes are formed within that occasion.
