Document Summary

Chapter 3: perception: the nature of perception. Perception extends beyond identifying objects of helping us take action within our environment. Perception is the gateway to all of the other cognitions.

Processing that begins with the stimulation of receptors: first step of perception is stimuli of receptors by environmental stimuli. Since feature detectors fire to a specific aspect of tree, then our overall perception of the tree is created by combining this information. Rbc proposes objects are perceived via elementary features called geons.

Bottom-up processing may determine individual geons that make up an object, but additional processing is needed to combine them to create an object.
