Welcome to the Ladder Lab website! The Literacy and Deafness Development Research Lab (LADDER Lab) is made up of a group of researchers based at the Deafness, Cognition and Language Research Centre (DCAL) at UCL and City, University of London. We are interested in understanding how literacy and language skills are acquired, and investigating the underlying cognitive processes involved in literacy development.

Some hearing children and many deaf children have language delays and find reading challenging. It is important to understand how, and when, the language and reading processes can break down in order to devise effective interventions to remediate difficulties. As part of this work to identify difficulties, we have developed a range of assessments to measure language skills. We work with practitioners and other key stakeholders.
We have several exciting projects looking at language skills and reading development in children. Follow the links below to find out more.
