Professor Olson received his Ph.D. in experimental psychology
from the University of Oregon in 1970. Since then he has been
a faculty member at the University of Colorado, where he is
now Professor of Psychology, a Fellow of the Institute for
Behavioral Genetics, and Associate Director of the Center
for the Study of Learning Disabilities. He is a charter member
of the Society for the Scientific Study of Reading and currently
serves as President. He currently serves on the editorial
boards of the Journal of Experimental Child Psychology, the
Journal of Learning Disabilities, and the Journal of Educational
Psychology.
Professor Olson's research since 1980 has focused on the
etiology and remediation reading disabilities. Data from identical
and fraternal twins have been used to assess the genetic and
environmental influence on reading and related language deficits.
linkage analyses of the fraternal twins have isolated a region
on the short arm of chromosome 6 related to these deficits.
The remediation of reading and language deficits has been
explored through the use of computers in the Boulder schools.
Most recently, Professor Olson began a 5-year longitudinal
preschool twin study for developmental genetic analyses of
reading and attention.
