Our senses aren't just delivering a strict view of what's going on in the world; they're affected by what's going on in our heads. A new study finds that hungry people see food-related words more clearly than people who've just eaten. The study, published in Psychological Science, a journal of the Association for Psychological Science, finds that this change in vision happens at the earliest, perceptual stages, before higher parts of the brain have a chance to change the messages coming from the eyes.
