And how would Gibson explain ambiguous stimuli where the identical input gives rise to different interpretations?

Hebb's distinction between sensation and perception as a way of distinguishing bottom-up and top-down processing. Hebb defines sensation as activity in the sense organ and corresponding sensory receiving areas of the brain. You can easily illustrate this with a diagram, say for the visual system. Perception is then what occurs when this information is sent on to other parts of the brain and interpreted in the light of context and past experience (top-down processing).

Student question: How can it be truly bottom up if it requires a comparison to a stored image? Isn't that like top-down? You use the stored image to recognize what it is that is coming in. How are these actually different? I did have a response but I want to withhold it from here so not to bias responses from the list. Student question: Is there any real life example of people using template models of pattern recognition? If not, why did they even get developed as models of human pattern recognition? My answer here was really lame, IMHO so I am looking for a better one but as above, don't want to bias responses. Maybe I'm particular brain dead that these two stumped me.
