Document Summary
You remember countless faces, places, and happenings; tastes, smells, and textures; voices, sounds, and songs. In one study, students listened to snippets a mere four-tenths of a second from popular songs. More than 25 percent of the time (krumhansl, 2010). We often recognize songs as quickly as we recognize someone"s voice. Imagine viewing more than 2500 slides of faces and places for 10 seconds each. Later, you see 280 of these slides, paired with others you"ve never seen. Actual participants in this experiment recognized 90 percent of the slides they had viewed in the first round (haber, 1970). In a follow-up experiment, people exposed to 2800 images for only 3 seconds each spotted the repeats with 82 percent accuracy (konkle et al. , 2010). Some super-recognizers display an extraordinary ability to recognize faces. Eighteen months after viewing a video of an armed robbery, one such police officer spotted and arrested the robber walking on a busy street (davis et al. , 2013).
