Mere-exposure effect

Urban Farm DB summary

The mere-exposure effect is the phenomenon whereby liking increases simply from familiarity with a stimulus, also called the familiarity principle in social psychology. Robert Zajonc led research on it from the 1960s to 1990s, showing that an initial fear/avoidance response to novel stimuli decreases with repeated exposure and turns into liking. A meta-analysis of 208 experiments by Bornstein (1989) found an effect size of r=0.26, with the effect typically reaching its maximum within 10-20 presentations.
