Sensation: Vision


IN the above TED Talk, the presenter discusses the fact that our brain is heavily involved in our visual perception and that context has a massive impact on perception.


This is the KEY difference between sensation and perception.  Perception is what’s referred to as “top down processing” in short, it involves the brain and cognition whereas sensation is bottom up processing and is based off biological senses and is more “automatic” thus lacks processing by higher brain regions.

Context has a major effect on perception of all types of stimuli, but the above TED talk brilliantly illustrates the context effects on vision!
