Visual Perception 1 / Top-Down Visual Processing


This is an image from the well known puzzle book, "I-Spy," that most of us owned and played with as children with friends and family.  This puzzle from "I-Spy" denotes top-down visual processing because it allows us to create a goal in trying to find all the pictures listed in this picture to move on to the next picture, and then so to completing the book.  You first start with the larger concept of the idea here, then work your way down to the finer details in completing your task.  This means we first take the image in as a whole, then focus in on one particular item we must find.  Once we are set on that item, we scan the image consistently and quickly, looking for the image with rapid eye movement.  When we register the item we are looking for, we set a goal to find the next listed item on our list and so on.  Top-down processing is just starting out with the high-concept ideas and then focusing in on the minor and finer details.  I also like this particular image from the book because of its graphic layout, and the glow in the dark overlay they used in the pictures.
