Description
A minimal approach to the measurement problem and the quantum-to-classical transition assumes a universally valid quantum formalism, i.e. unitary time evolution governed by a Schrödinger-type equation. As had been pointed out long ago, in this view the measurement process can be described by decoherence which results in a "Many-Worlds" or "Many-Minds" scenario. A silent assumption for decoherence to proceed is however, that there exists incomplete information about the environment
our object system gets entangled with in the measurement process. This talk addresses the question where this information is traced out and - by adopting recent approaches to model consciousness in neuroscience - argues that a rigorous interpretation results in the notion that the information that is or is not available in the consciousness of the observer is crucial for the definition of the environment. As such the Many-Worlds-Interpretation while being difficult or impossible to probe in physics may become testable in psychology.
