So first the perception process. theThe first stage is sensation observation so- you touch, hear, smell, or taste things and the sense organs transferredtransfer this external stimulation into an internal currency, which isnamely electricity.
theThe second step is processing the information the electric impulses that go to your brain the: it is the brain's job is to process this information.

in there is the form of electrical impulses.

The main programming that influences our perception is social culture: sohow we are raised and so our parent’s, interactions arewith parents, our experiences in the world that later in the, school and then, TV, friends, religious organizations, marketing, governments, react programmed by the whole society weetc. We are the product of the society.
weWe are created to interpret the external stimulations that becamebecome electricity, and it'sthis is socially interpreted. soSo when something happens then, you get the information there the stimulation(the stimulation), but you are already selective already because, depending on your mental, physical and emotional state, you pay attention to what you're more sensitive to.
