ľ¹Ï¸£ÀûÓ°ÊÓ

Bilingual infants have astonishing learning capabilities that allow them to learn sound properties of two different languages in the first year of life. But how do they discover and distinguish two languages in their speech environment? In this project, you study how the speech sounds that infants hear at home guide their discovery of two languages. Taking an interdisciplinary approach, the project aims to collect and analyse bilingual infant-directed speech, test infants’ reliance on sound cues, and use computational models to simulate the learning of two languages from speech.

Your job

In the PhD subproject, you work with Dutch-English bilingual families to collect and analyse a corpus of bilingual infant-directed speech. You also study bilingual infants’ language discrimination skills using headturn-preference experiments. In this research programme, you work in an interdisciplinary team with researchers from the fields of linguistics, psychology, and artificial intelligence. You receive assistance from student assistants in data collection and/or data processing and develop your academic teaching skills (during your project). The project will be carried out at the Institute for Language Sciences (ILS), at Utrecht ľ¹Ï¸£ÀûÓ°ÊÓ, the Netherlands.

Your tasks include:

• completion and defence of an article-based PhD thesis within four years (including studying relevant literature and writing the articles);
• presenting intermediate research results at workshops and conferences regularly;
• publication of peer-reviewed articles in established international journals;
• participation in training programmes and expert meetings organised for the project group;
• participation in relevant training programmes provided by the Institute for Language Sciences (ILS), the Utrecht ľ¹Ï¸£ÀûÓ°ÊÓ graduate school, the National Graduate School of Linguistics (LOT) and other organisations;
• co-organisation of project workshops and conferences.

Your qualities

• An (R)MA degree in linguistics, psycholinguistics, psychology, artificial intelligence, or a related discipline in hand by the starting date; 
• affinity with research on infant language development;
• demonstrable knowledge in at least one of the following areas: phonetics, phonology, language development, early speech perception, bilingualism;
• a high proficiency in English and Dutch;
• readiness to learn new experimental methods and statistical analyses;
• the skills to work both as an independent researcher and as a team member;
• strong organisational, social and communication skills;
• prior experience with infant research and/or quantitative linguistic research methods is a plus.

Our offer

• A position for 18 months, with an extension to a total of four years upon a positive evaluation;
• a working week 1,0 FTE (38 hours) and a gross monthly salary between €3,059 and €3,881 (salary scale P under the Collective Labour Agreement for Dutch Universities (CAO NU));
• 8% holiday pay and 8.3% year-end bonus;
• a pension scheme, partially paid parental leave and flexible terms of employment based on the CAO NU.

In addition to the terms of employment laid down in the CAO NU, Utrecht ľ¹Ï¸£ÀûÓ°ÊÓ offers a range of its own schemes for employees. This includes arrangements for professional development, various types of leave, and options for sports and cultural activities.
