Mere exposure effect
Robert Zajonc (1968) showed that repeated exposure alone increases liking for words, symbols and faces. A common explanation is perceptual fluency: familiar stimuli are easier to process, and that ease is felt as liking. Examples include brand logos, jingles, neighbours and songs. Meta-analyses (Bornstein, 1989; Montoya et al., 2017) confirm the effect but show an inverted-U: too much exposure brings boredom, and initially disliked stimuli may become more disliked.
