  CSL and conscious perceptions. One interesting feature of CSL is that when conscious perceptions are involved, the collapse time of two brain states in a superposition and the time which is necessary for the emergence of a definite perception, are quite similar, and this has some (small but significant) implications concerning the probabilities of the outcomes. This point has been analyzed in detail and explicitly evaluated by resorting to a simple model of a quantum system subjected to reduction processes (Ghirardi &amp; Romano 2014). The idea is to consider a spin 1/2 particle whose spin rotates around the x-axis with a frequency of about one hundreth of the one of the random measurements ascertaining whether its spin is UP or DOWN with respect to the z-axis. It turns out that for a superposition with amplitudes \(a\) and \(b\) of the two eigenstates of S\(_z\), the probability of the two supervening perceptions associated to the two outcomes will differ of about 1% from those predicted by quantum mechanics, i.e. \(\lvert a\rvert^2\) and \(\lvert b\rvert^2\), respectively.
