Document Summary

The process of perception and introducing subliminal messaging. Perception is the core of all human interaction. The process of perception occurs these steps: reality. E. g. light from outside objects reach the eye, where photosensitive chemicals create a cascade of information transfer to then create neural information: transduction. Physical energy of the stimulus is converted to electrical energy, which is sent in pulses to the brain: thalamus. Information from transduction is then sent to sensory processing areas via the. Thalamus a doctrine of speci c nerve energies". Note that most senses (except smell) are in uenced by the thalamus: primary processing; primary sensory/visual cortex (psc/pvc) At this stage, one"s conscious processing of information begins. Here, interpretations are formed: further processing. Other brain areas, linked to higher-level cognitive and perceptual tasks, process this information further. Think of the what" and where" pathways: deciding and acting. More brain areas (responsible for memory, morale, planning, discipline, etc. ) then make decisions on what to do.
