Leonardo DaVinci said: “all our knowledge has its  origins in our perceptions. ALL AUDIENCES have certain truths; ways in  which they perceive information Sensation and Perception represent polar  opposites of a continuum by which we gather,  store, retrieve and apply data

Is the PHYSICAL part of collecting data Requires four items: Stimulus in the world A sensory organ that takes the data, and encodes it into  a neuronal impulse Nerve pathway to carry the impulse to the brain An area of the brain to receive and process the impulse

An example of Sensation: You see a stop sign – the stimulus is the stop sign, the  sensory organ you use to receive that stop sign is visual Your eyes push that visual to your brain Your brain processes the shape of the sign, the color, the  fact that it’s sitting at an intersection The brain recognizes it as a traffic sign

Pre-attentive processes occur lightning fast In our stop sign example, the time it takes from first  seeing the sign to actually stopping is very, very short.  Pre-attentive processes operate quickly, randomly and  without conscious thought. Attentive Processes involve calling on knowledge,  learning, memory and understanding. For instance – reading requires attentive processes to  organize, understand and process the text
