Fernald et al. (2013) also found that by 18 months old language processing and vocabulary disparities were already evident, and by 24 months old there was a 6-month gap between the SES groups in processing skills critical to language development. [4] Fernald et al. found fast reaction time as a child can translate into reaction time as an adult.
Vocabulary development is a process by which people acquire words. Babbling shifts towards meaningful speech as infants grow and produce their first words around the age of one year. In early word learning, infants build their vocabulary slowly. By the age of 18 months, infants can typically produce about 50 words and begin to make word ...
[47] [48] [49] Infants between 21 and 23 months old are also able to use statistical learning to develop "lexical categories", such as an animal category, which infants might later map to newly learned words in the same category. These findings suggest that early experience listening to language is critical to vocabulary acquisition.

The cognates in the table below share meanings in English and Spanish, but have different pronunciation. Some words entered Middle English and Early Modern Spanish indirectly and at different times. For example, a Latinate word might enter English by way of Old French, but enter Spanish directly from Latin. Such differences can introduce ...
Around this time, toddlers generally know about 50 words. At 21 months is when toddlers begin to incorporate two word phrases into their vocabulary, such as "I go", "mama give", and "baby play". [citation needed] Before going to sleep they often engage in a monologue called crib talk in which they practice conversational skills. At this age ...
This task shows that children aged 15 to 20 months can assign meaning to a new word after only a single exposure. Fast mapping is a necessary ability for children to acquire the number of words they have to learn during the first few years of life: Children acquire an average of nine words per day between 18 months and 6 years of age.
