📖 Reading Passage
The Mere Exposure Effect refers to the psychological phenomenon where people develop a preference for things simply because they are familiar with them. This effect occurs even when the initial exposure is subliminal or unnoticed. Studies show that repeated exposure to a stimulus, such as a sound, image, or person, increases positive feelings toward it, regardless of conscious awareness. The effect is robust across various contexts and has been demonstrated in experiments involving faces, words, and melodies. Researchers believe this bias arises from evolutionary advantages—familiarity often signals safety, whereas novelty may indicate potential threat.

Professor: Now, let me give you a classic example from a study. Researchers showed participants a series of random, unknown symbols—like shapes from an ancient language—on a screen. Each symbol appeared only for a fraction of a second, too fast to consciously register. Some symbols were shown repeatedly, say twenty times, while others appeared only once. Later, when participants were asked to rate how much they liked each symbol, they consistently rated the ones they had seen more often as more pleasant and appealing. Interestingly, when asked if they recognized any symbols, they couldn't distinguish which ones they had seen. So, even though they had no conscious memory of the exposure, the repeated ones felt better. This demonstrates the mere exposure effect in action—familiarity, even at an unconscious level, boosts our preference.
