Most of my early work compared signed and spoken language acquisition. The existence of SLI in signing children and gestures in hearing people with language difficulties. Other interest has been in the relationship between language and cognitive development in Theory of Mind and Executive Functions. My current work is moving towards why there is so much variability in how completely deaf children learn spoken language.

Research Overview

1. Vision


In my research and teaching I ask questions about how children develop language, social-cognitive and academic abilities and why in some cases this natural development goes awry. I am committed to making my research inform social and educational policy. The Economic and Social Research Council (ESRC) has funded by work continually since 1994.

Language acquisition by Eye

My main research centres on language acquisition and cognitive development. In a series of projects I have established that young children adapt to a dramatic shift in how language is accessed through visual sensory input to follow normal milestones in language development. My work has shown that deaf children of deaf parents acquire sign languages in comparable ways to children learning spoken languages at the phonological, morpho-syntactic and pragmatic levels. This switch in modality provides a window onto the amazing robustness of child language acquisition and the plasticity of the human system for communication. At the same time language acquisition in the visual modality has some impact on the ways children develop signing and how adults interact with signing children.

From 1995 onwards I carried out field work and education projects with the deaf community of Nicaragua where I witnessed an extreme example of the language making capacity of young deaf children. In other work more recently I have been exploring the phonotactic regularities of signed languages and how this aids comprehension. This work is at the level of adult signers segmenting real signs from non-sign sequences. The next step will be to look at how these abilities develop in young children. The goal of this line of research is to further the study of language acquisition in general by demonstrating the unique differences in development stemming from the input in another modality as well as comparing the universal patterns in development that appear despite this modality shift. One current example study is the role of iconicity in early sign acquisition and its overlap with early co-speech gesture and action.

Deafness, Cognition and Language

Since the establishment of the Deafness Cognition and Language research  centre (DCAL) in 2006, my language acquisition work has extended out to the development of social-cognition in deaf children and in particular Theory of Mind (ToM). I am interested in how ToM emerges through early communication and is triggered by language experience. In the context of 95% of deaf children experiencing late and impoverished access to language the question of how ToM develops with or without links to language is intriguing. This work began in the Nicaraguan deaf community. This study revealed aspects of ToM can develop even in the face of very late language acquisition. Currently I led a large study of British 2-4 year old deaf children from deaf and hearing parents. In this work we evaluated parent-child communication and its influence on implicit and explicit ToM reasoning. The findings of this research link to theories of ToM development and deaf children's educational and social development. Currently in this line of research I am currently studying the development of executive functions in deaf children.

Disruption to development or processing of language

My other main interests are atypical language and cognitive development. I led a study of a large group of deaf children who have specific language impairments (SLI). Despite normal intelligence, social and linguistic stimulation they are not picking up the rules of language. This is the first study in the world to look at this population. The results will lead to a greater understanding of what the core SLI deficit might be (if there is a single one) as well as more effective language intervention for deaf children. In other projects I am following the linguistic savant Christopher's development of sign language, hearing children and adults' use of gesture with developmental and acquired language impairments and the effects of visual impairments on sign language structure. The goal of this line of research is to understand more about the language and cognitive architecture of the typical individual by investigating disruptions and dissociations.
