Orch OR Model of Consciousness: Experimental Evidence Part II  Vanessa Buechner (Psychology, University of Munich, Munich, Germany)   P2

Recently, Penrose and Hameroff (2011) proposed a model of consciousness and quantum computations originating from the mid 1990's. According to this model consciousness depends on biologically 'orchestrated' quantum computations in collections of microtubules within brain neurons. The continuous Schrodinger evolution of each quantum computation terminates a quantum-gravity process related to the fundamentals of spacetime geometry. This process is called 'objective reduction' of the quantum state (OR) and results into a moment of conscious awareness. Any brain activity within the microtubuli that occurs before the 'objective reduction' follows quantum mechanical rules in line with Schrodinger's equation. Also, as mentioned above, OR indicates a conscious moment implying that quantum states need to be - by definition - preconscious. One core feature of quantum physics is that time has no direction (Penrose, 1994), i.e. future and past are interchangeable and this should consequently apply for preconscious processing, as well. In a second set of experiments, we extended the findings of Maier (in this volume) using the same subliminal presentation technique. First, we tested the effect of erotic picture material on preconscious decisions (see Bem, 2010, Exp.1). In two additional studies, we tested the influence of trial randomization on our results. We randomly activated a specific trial by using a quantum-based RNG both before and after participants' decisions to rule out alternative explanations of our effects. In addition we tested possible moderating factors such as personality traits.
