Document Summary
Chapter 3: perception: perception: experiences resulting from stimulation of senses, bottom-up processing: processing that begins with stimulation of receptors. Stimulation of receptors trigger a series of events in which electrical signals are transmitted to the brain. Neurons that respond to simple shapes (lines), called feature detectors. Airplane with 3/9 geons 78% recognition with 6/9 96%: principle of componential recovery: ability to recover obscured geons if we can recognize the object (flashlight) When the corners/intersections are covered we cannot recognize them. We are able to recognize certain arrangements of geons because of our prior experience/knowledge: top down processing: processing that begins with a persons prior knowledge. Also involved in our ability to recognize an object with geons missing. Also supported by the brain getting signals about background information (feedback signals) A blob is perceived as different objects depending on its orientation and context.
