The Investigation of Negative Particles in SLI Children

The investigation of SLI children's ability to produce and comprehend syntactic negation has provided a new perspective on a range of existing research findings (Lee Davies, PhD). As well as holding a number of interesting characteristics which have not previously been examined in SLI research, negation provides a useful diagnostic for a range of syntactic movement processes, an area which is particularly pertinent to the RDDR research program cf. van der Lely, 1994, 1998. Davies' study focuses upon a range of abilities, including the production and comprehension of simple negatives, the production and comprehension of negative questions, and the comprehension of negative scope. The findings from this study are discussed in Davies and van der Lely, 2000; Davies, 2001, PhD UCL; and Davies 2001, in press.
