Even before uttering their first words, babies master the grammar basics of their mother tongue. Thus, eight-month-old French infants can distinguish function words, or functors — e.g. articles (the), personal pronouns (she), or prepositions (on) — from content words — e.g. nouns (rainbow), verbs (to drive), or adjectives (green). Functors are frequently encountered because there are fewer of them, and they are placed before content words in languages such as English and French.

Function words distinguishable at 8 months

In contrast, there is a much greater diversity of content words, which are also longer. Experiments conducted by three researchers from the Integrative Neuroscience and Cognition Center (CNRS/Université de Paris) with 175 eight-month-old babies, using a simple artificial language, demonstrated that these infants understood functors were more frequent and came before content words in their mother tongue (French).

Quick adaptation to new content words but little interest for new functors

The young participants quickly adapted to new content words but showed little interest for newly introduced functors — as though already aware there were only a limited number of prepositions, determiners, and other words in this category. Babies’ preferences were evaluated by observing how long they looked at visual displays associated with the grammar words. This study appears in Current Biology, 12 March 2020.
