Child participating in the study (IMAGE) CNRS Caption Babies listened to a four-minute recording--in a simple artificial language--in which frequent words, imitating functors, alternated with rarer ones, imitating content words. Then they heard short sentences in the language, half of which adopted French word order (frequent-word-initial). During this part of the experiment, a longer gaze was interpreted as a sign of the infant's preference.
