Recently we published on International Journal of Theoretical Physics an answer to G. Ghirardi relating a paper published by this author in 1999. Since the argument is so complex and articulated, in the present paper we add further comments relating in particular the matter of the quantum collapse as we have elaborated it in our previous work using only Clifford algebra and thus reaching the basic result that it is a mechanism involving only information with a cybernetic collapse and retrocollapse dynamics as first it was introduced by Costa de Beauregard. We evidence as quantum collapse involves directly our psyche and our consciousness that of course is by itself an entity selecting alternatives on the basis of quantum rules. According to our previous experiments we also add comments on the possibility to estimate quantum interference at the level of perception and cognitive dynamics and reconstruct the wave function giving the possibility such result to discriminate between pure quantum superposition of states and mixtures just to re-confirm the role of quantum mechanics at the basic structure of mental entities.

Recently we published a paper on Int. Journal of Theoretical Physics (IJTP), entitled Answer to Giancarlo Ghirardi: Quantum Super Positions and Definite Perceptions: Envisaging New Feasible Experimental Tests. A Novel Proposal for Quantum Mechanics, Perception and Cognitive Science? [

The purpose of this paper is to introduce further comments with respect to the published text of JITP in order to expose, to develop and to specify in more detail the issue.

The object of Ghirardi’s paper is well clear and carefully understood. The paper was devoted to analyzing the possibility of checking experimentally whether the perceptual process can lead to the collapse of the wave function.

Apparently it could seem that in our response we left a lot of us from the object of Ghirardi issue but instead the connection is very clear if we look at some of our previous results. We intend to take into account the results that in 2010 we published on IJTP [

According also to Gottsemann and Chuang [

This result, obtained on the basis of strictly mathematical theorems and as devoid of any notion of physics and adoption of any physical model of interaction microscopic quantum system and measuring instrument, together with a number of other results obtained in recent years and strictly indicated in the bibliography of [

There is another argument that it is necessary to deepen. As previously said, quantum collapse may be discussed only involving a semantic act and the role of our consciousness that selects on the basis of quantum rules. In addition, neurophysiology should be considered in this case: the visual system in humans and animals allows individuals to assimilate information from their surroundings. The act of seeing starts when the lens of the eye focuses an image of its surroundings into a light-sensitive membrane in the back of the eye, called the retina. Here is a crucial point: according to the standard view retina may be intended as a simple photodetector but really the retina is actually part of the brain, also if it is isolated to serve as a transducer for the conversion of patterns of light into neuronal signals. Again the relation to the role of quantum mechanics in the perceptual and cognitive processes is directly involved.

Finally, let us explain again what is the reason to consider quantum collapse and the importance to accept that it is induced by human mental entities. We evidenced previously that during quantum collapse transition the dynamics of information must be taken in serious consideration. As for the CT invariance of the Feynman propagator, the causality asymmetry it entails is factlike, not lawlike. The geometrical counterpart of the symmetry between prediction and retrodiction and between retarded and advanced waves, as expressed in the alternative expressions

This is the reason because quantum collapse is so important and it is a so complex action that cannot be ignored in every proposed experiment.

Finally we would add a final comment on other features introduced in the first answer. In fact, we have to remember here that in recent years we produced also a large number of experimental confirmations and in particular at the level of perception, using ambiguous figures but also at cognitive level using other basic processes of the neurobiology as the Stroop effect and some cognitive anomalies as the Conjunction fallacy. We gave evidence of violation of Bell’s inequality at the cognitive level using the Clifford algebra. All the experiments confirmed that, in violation of the basic standard Bayes theorem, used probabilities confirmed the presence of the term of the quantum interference which is characteristic of only and only processes that fall under the domain of quantum mechanics. The estimate of the quantum interference factor is important not only to confirm the role of quantum mechanics in perceptive and cognitive level but because it allows us to reconstruct a posteriori the wave function of the system examined. It is well known that the wave function is not an observable entity in the formulation of quantum mechanics but can be rebuilt in retrospect, starting from the experimental estimate of the quantum interference factor. The confirmation of the presence of this abstract entity (the reconstructed wave function) at perceptual and cognitive levels is a marker evidencing the role of quantum mechanics at this level of our mental entities. In particular our formulation also allows discrimination between the quantum case instead of mixtures. This argument was processed in detail by us in many papers, and, in particular, in pages 530-531 of the paper Entitled “On the possibility that we think in a quantum probabilistic manner”, Neuroquantology [
