Outcome measures
Primary outcome
This research project involves the use of three well-established ERP components
to tap into different levels of phonological processing in the brain: 1)
Mismatch negativity to explore the development of phonological representations,
2) ERP auditory rhyming effect to investigate early stages of phonological
awareness, and 3) the go/no-go N200 effect to track the development of
phonological segment recognition. Also the behavioral responses of the subjects
like response latencies and accuracy will be measured.
Secondary outcome
n.v.t.
Background summary
In the first few months of first grade children learn how to read. This process
is preceded by the development of an awareness that the stream of spoken
language can be divided in sentences, words and phonemes: phonological
awareness. Phonological awareness develops during childhood, but continues to
grow in first grade and has a reciprocal relationship with the reading process
(Blachman, 2000). About five percent of the population develops reading
problems as a result of a phonological deficit. It is still unclear why some
children with an auditory deficit develop a phonological deficit and reading
problems, and some not. Therefore research is needed into the specific nature
of an auditory deficit and the causal relationship between phonological
awareness and reading.
Study objective
Uncover the role of auditory and phonological factors in early literacy.
Study design
This study is designed as a behavioral longitudinal study in which children
with a genetic risk for dyslexia and phonological problems will be followed
from the last year of kindergarten to the end of second grade and compared to a
control group of normally developing children.
Study burden and risks
There are no risks associated with the study. The burden for the children is
extremely low. The EEG will be recorded using ActiCap electrode sets. These
caps are easy to apply, and especially suited for testing children. EEG
measurement will take place in a minivan that is especially designed to test
children at the location of their school or home, which minimizes the burden
even further. Momentarily the minivan and all products are successfully used at
the Behavioural Science Institute and the F.C. Donders Centre for Cognitive
Neuroimaging for EEG recording in kindergartners, primary school children, and
young children suffering from cerebral palsy. Experimental tasks are designed
in such a way that they can be easily carried by the study population to keep
the cognitive burden at a minimum.
