Mere-exposure effect - Wikipedia: Two-factor theory[edit]
The mere-exposure effect has been explained by a two-factor theory that posits that repeated exposure of a stimulus increases perceptual fluency which is the ease with which a stimulus can be processed. Perceptual fluency, in turn, increases positive affect.[11][12] Studies showed that repeated exposure increases perceptual fluency, confirming the first part of the two-factor theory.[13] Later studies observed that perceptual fluency is affectively positive, confirming the second part of the fluency account of the mere-exposure effect.[14][15]
