Cognitive decision processes are generally seen as classical Bayesian
probabilities, but better suited to quantum mathematics. For example: 1)
Psychological conflict, ambiguity and uncertainty can be viewed as
(quantum) superposition of multiple possible judgments and beliefs. 2)
Measurement (e.g. answering a question, reaching a decision) reduces
possibilities to definite states (‘constructing reality’, ‘collapsing the
wave function’). 3) Previous questions influence subsequent answers, so
sequence affects outcomes (‘contextual non-commutativity’). 4) Judgments
and choices may deviate from classical logic, suggesting random, or
‘non-computable’ quantum influences. Can quantum cognition operate in the
brain? Do classical brain activities simulate quantum processes? Or have
biomolecular quantum devices evolved? In this talk I will discuss how a
finer scale, intra-neuronal level of quantum information processing in
cytoskeletal microtubules can accumulate, operate upon and integrate
quantum information and memory for self-collapse to classical states which
regulate axonal firings, controlling behavior.(video)
