| Chapter 3: Perception What happens when visual information has entered our system? Template models: input is matched to mental model of a specific object; cannot account for variability in environment. Feature detection models: Features are very basic elements. Cells in the visual cortex are specialized to detect them. Features are assembled through bottom-up processing to form higher-level information. Yet our brain is full of information already, and it helps processing in a top-down manner by actively matching input and already held knowledge. |
