ABSTRACT
As an interpretation of quantum mechanics, QBism has also accepted cognition as a central tenet that allows the Born rule of quantum mechanics to be viewed as a ‘normative rule’ rather than a natural law. According to the Britannica Online Encyclopedia, ‘Cognition includes all conscious and unconscious processes by which knowledge is accumulated, such as perceiving, recognizing, conceiving, and reasoning’. The main types of cognitive processes are attention, language, learning, memory and thought. Neuroscience deals mainly with the brain architecture and brain phenomena like neuron firings that accompany cognitive processes. Its main tools are functional magnetic resonance imaging and positron emission tomography. The influence of the body on the mind and cognition was recognized thousands of years ago in India, resulting in yoga practices coupled with meditation for mind control. Contextuality-complementarity seems to be a universal principle, but its exact meaning or the way in which we measure them varies in subtle ways between quantum physics and cognition.
