In an early demonstration of the mere exposure effect, participants in an experiment were exposed to a set of alphabets from the Japanese language. As most people know, Japanese alphabets look like drawings and are called ideograms. In the experiment, the duration of exposure to each ideogram was deliberately kept as short as 30 milliseconds. At such short durations of exposure-known as subliminal exposure-people cannot register the stimuli and hence, participants in the experiment were not expected to recall seeing the ideograms. Nevertheless, when participants were shown two sets of alphabets, one to which they had been previously exposed and another to which they hadn't, participants reported greater liking for the former even though they couldn't recall seeing them! These results have been replicated numerous times and across a variety of types of stimuli, so they are robust. What the mere exposure results show is that _______________________________________________.
- ①we can learn the Japanese language with extensive exposure.
- ②duration is responsible for the robust results across studies.
- ③it is impossible to register the stimuli at short durations.
- ④people develop a liking towards stimuli that are familiar.
