Hi Annette, I would argue that both bottom-up and top-down work together and are both ways of describing things from different perspectives. We assemble the sensations into a whole--for example, in vision we assemble the size, shape, movement (or lack thereof), color, and other components into a cohesive whole (where the "binding" occurs is up for grabs). Then we take that assemblage and make our best guess about what it is using prior experience. Usually it works, occasionally it doesn't. My most graphic (to me) example is when I looked at two somewhat dim, red lights on a dark county highway that I perceived as reflectors guiding my path. It wasn't until I crashed into the back of a stopped pickup truck that I realized my top-down processing led me to the wrong assumption. Luckily, nobody was hurt (though the car was totaled). Since I no longer trust my night driving, I've become verrrrry cautious and attempt to assure myself that it is in fact a highway before me. Carol
