LUCL labs

The LUCL Babylab was first opened in 2008 in the Leiden University’s Social Sciences faculty at the Pieter de la Court building. A new Babylab was opened in the Lipsius building in 2015 with Claartje Levelt as its director.

The Leiden Babylab is a welcoming environment for babies with a spacious sound-attenuated booth and two workstations and a live video monitor and recording device. In the Babylab, research is done on how infants and young children learn different aspects of their first language or multilingual children process language.  

Baby behaviour

The LUCL Babylab still collaborates actively with the Babylab in the Social Sciences faculty in sharing a common database of participants. In addition, a Near-Infrared Spectroscopy (NIRS) machine is shared between the two babylabs, which allows researchers to shine a harmless infrared light into babies’ skulls, allowing us to see how blood flows in the infant brain in response to the presentation of various auditory or visual stimuli.  

In the LUCL Babylab, we test how babies learn different aspects of speech and language, typically by using a simple behavioral measure: the baby’s attention and interest. Babies naturally turn towards things they are interested in, and turn away from what they are bored with. This natural behavior is at the heart of the Head-turn Preference Paradigm, which we use to test whether infants can tell the difference between different types of stimuli, whether they be different languages, different vowels or consonants, different intonations. 

The Babylab is situated in the Lipsius Building room 1.10.
