Dyslexic Children Learn a New Visual Strategy for Reading:
a Controlled Experiment
Gad Geiger, Jerome Y. Lettvin and Manfred Fahle
Recent studies by Geiger, Lettvin and ZegarraMoran have proposed a new nonreading
test for the diagnosis of dyslexia, and a new method for remediation. The
latter involves the learning of a "visual strategy". On adult
dyslexics the test was reliable and the remediation apparently effective.
The purpose of this study is to confirm the usefulness of the remediation
and test with children. Dyslexic children (3rd - 6th grade) were divided
into two groups. The experimental group (9) was given a new remedial regimen
of practise. The control group (6) continued the remedial process given
in their school. After 3 months of practising their separate regimens all
the dyslexic children who were in the two groups were retested and compared.
The "experimental" dyslexics improved in reading by 1.22 grade
level on average while the "control" dyslexics improved by 0.17
grade on average. The formresolving field (FRF) plots narrowed significantly
for the experimental dyslexics while they changed little for the control
dyslexics. At the end of the second testing the control dyslexics were also
given the new regimen of practise. Five months later all the dyslexic children
were tested for the third time. The initial control dyslexics who later
practised the regimen (2) improved in reading by 2 2.5 grades and their
FRF plot narrowed. The experimental dyslexics continued to improve yet further.
All the dyslexic who practised the new regimen started at an average of
2.5 grades behind their expected grade/age level and after 8 months were
at an average 0.75 grades behind their expected grade/age level. This is
on average 1.75 grade level improvement in reading within 8 months, a rate
of improvement larger than that of ordinary reading subjects. The dyslexic
children were compared with matched grade/age ordinary reading children
for reference. The study confirms the usefulness of the test and the applicability
of the remediation method for children. It also shows that improvement under
that method is quite rapid.
