Read the underlying intention

To determine the meaning of words, language learners need to pay attention to what other people are saying. However, it is advisable for a young language learner to simultaneously encode relevant non-verbal cues, for example by following the direction of eye gaze. Sensitivity to cues such as gaze may be particularly important for intercultural children, as they find less consistency between words and objects than monolingual children and do not always have access to the same word learning strategies (i.e. an entity may have more than one label).

Similarly, we quite often communicate things in an indirect way. Instead of saying “Close the door”, we say “I think there’s a draft”. Because it is more polite, because it signals reasons for the wishes to the person addressed, because it gives them freedom as to whether and in what way they comply with the wish. The person being spoken to has to understand the underlying wishes of the statement by reconstructing the relevance for him/herself: Why did she say that, what does she want to achieve? This happens in all languages, but the demands on intention comprehension may be language-specific.


In this research project I am investigating: How do intercultural children understand the intentions of others? Is the search for intentions universal? Are the means and ends different? How does the ability to understand intentions affect linguistic abilities?

We tested a total of 93 6‐ to 9‐month‐old and 229 12‐ to 15‐month‐old monolingual and bilingual infants, in 11 laboratories located in 8 countries. Monolingual and bilingual infants showed similar gaze‐following abilities, suggesting that gaze sensitivity is a fundamental aspect of development that is robust to variation in language exposure.

Infancy

3-year-old monolingual and bilingual children understand indirect communication. The existence and amount of further language input does not affect the interpretation of indirect meanings.Thus, seeking relevance seems to be a quite general disposition.

Cognitive Development

We explore whether early preference for Infant Directed Speech is linked to later vocabulary size. We are interested in investigating if the relation between IDS preference and vocabulary size changes over development; and if there is any systematic differences in the strength of this relationship across the language communities.
