Document Summary
More work is needed to specify how the brain detects and interprets the relationships that define each face. People are more accurate in recognizing faces of people from their own racial background. Some people are entirely prosopagnosic when viewing faces of people from other groups. People rely on different mechanisms same-race and cross-race face perception. Top-down effect effects driven by your knowledge and expectations. Ex. letter recognition is improved by context. Priming guarantees that detectors that have often been used in the past will be easier to activate in the future. Network learns which patterns are common/not. More receptive to inputs that follow the usual patterns. Other top-down effects require a different type of explanation. Ex. words are easier to recognize if you see them as part of a sentence than in isolation. Person needs to understand each of the words in the instructions. Person must understand the relations among the words in the instruction.
