The
cognitive function and structure of language processing in children
with SLI: A neuropsycholinguistic investigation
Questions
concerning the validity of SLI subgroups and whether domain-specific
or domain-general mechanisms underlie language processing are the
focus of work funding by the
Wellcome Trust, commencing in 2002. Recent work using event
related potentials (ERPs) to investigate the neural correlates of
sentence processing in children (Friederici & colleagues) has led
us to plan work on the neural instantiation of syntactic and semantic
processing in SLI and normally developing children. This work, to
be carried out in collaboration with Professors Angela Friederici
(director of
the Max-Planck Institute of Cognitive Neuroscience, Leipzig),
Johnson & Csibra (Birkbeck)
examines the syntactic and semantic processing of spoken sentences
and the effects of general cognitive load on sentence processing in
the G-SLI and WF-SLI subgroups. The research will test competing hypotheses
of SLI (the RDDR vs. Input-processing deficit hypotheses). By applying
cognitive-neuroscience methods to the study of SLI, we aim to examine
basic research questions through the study of language pathologies.
Several projects being carried out by postdoctoral fellow and as part
of doctoral studies are directly related to this work which is central
to the centre.
