A new study out this week found that infants as young as four months old understand and process faces like adults do. The authors say that this suggests that the visual cortex in our brain is already highly structured and formed by the time we are born.
Psychologists Link Emotion to Vividness of Perception and Creation of Vivid Memories - Psychologists overlaid images with visual noise to measure perception. After accounting for other features of images that contribute to perceptual vividness, such as contrast, color, and scene complexity, they found emotionally arousing images to be perceived more vividly, and thus contributing partly to more vivid memories of certain images later.
