My early work concentrated on comparisons between sign and
spoken language development and my PhD described this with
narrative skills. In most of the first studies I used
spontaneous language samples from 2 families of native
signers. During this period I co-edited the IASCL volume in
2002 on sign acquisition. My current work on language involves more
experimental studies with BSL in adults and also gestures and
spoken language in deaf children. This last factor is to do
with the changes in how spoken language is being used
increasingly by deaf
I have been looking at
language impairments in signing children and gestures in hearing
people with language difficulties. This research looks at common and differing patterns of breakdown.
Linked to this area I worked in my post-doc at UCL with Christopher
My other interest is the
relationship between language and cognitive development. I
have looked at this in relation to Theory of Mind and now with
the development of Executive Functions.
Gesture. In other
areas I am investigating how children
learn about iconicity and gesture. Linked to this last question I have been exploring how
signed languages have evolved from co-speech gesture and what
role language development (in adults and children) has played during this transition.
