英文摘要
The underlying hypothesis of the LDRC is that the neurodevelopmental
building blocks that support low level information processing (LLIP) are
specifically disordered in learning disabled (LD) children. This condition
results in a deficit in the normally rapid processing of temporal
information. The primary goal of Project IV is to provide, using the tools
that are unique to neurophysiology, an independent validation of the
hypothesized differences in LLIP between children with learning
disabilities and children without such disabilities.
As part of a coordinated effort with the other projects in the LDRC,
Project IV will evaluate 200 LD children and 200 children in the
standardization sample who, as part of Project I, will be defined and sub-
grouped based on profiles of strengths and deficits on "physiological-
plausible" variables of temporal information processing in the auditory,
visual, and motor sequencing domains. Project IV supports the basic
premise of the LDRC as stated in the Overview, namely that learning
disabilities represent a functional deficit. Project IV will rely on the
quantification of EEG data which is sensitive to the temporal aspects of
neural function to:
1) Derive neurophysiological measures of LLIP which are sensitive to
temporal information processing in visual, auditory, and motor systems
domains and which characterize learning disabilities.
2) Apply a standard neurophysiological test battery which has been used to
differentiate LD from normal children and to develop based upon this
battery basis neurophysiologic measures of processing including cortical-
cortical connectivity, spectral coherence; processing speed and
efficiency, evoked potential latency; and source and number of EP
generators, Brain Electrical Source Localization (BESA).
