Document Summary
Trying to separate physical energy components (pressure waves, light, molecules) which is the domain of sensation from the perceptual domain; being able to decode and understand what that is. There are lots of cues and hints in environment help us tell what we are looking at and where it is. Perceptual segmentation; how can i tell one object rom another (different between hand and piece of wood) if (cid:455)ou (cid:272)a(cid:374)"t do this, (cid:272)a(cid:374)"t ide(cid:374)tif(cid:455) this easil(cid:455) How would you pair them up: a and b then c and d, but why, through good continuation we infer that the best possible guess of this object is. Looks like it flows well, a flows well better into b then c or d. Not really, but you perceive it is one that smoothly continues: common movement; as someone moves, it is not like you start seeing them as separate objects because they are moving together in coherent smooth way, visual system.
