or even all three of these perspectives. Further, the number of chapters in
each part of the book reflects the number of authors contacted who actu-
ally provided chapters rather than the number of individuals from each
perspective who were invited to contribute.

We are grateful to Dean Birkenkamp, who originally contracted the
book for Westview, and to Cathy Murphy, our current editor at Westview,
for their support of the project, and to Marcus Boggs for his continuing
support throughout this and other projects. We also thank our students
and colleagues who have enabled us to develop and explore our interest
in learning disabilities. Robert Sternberg's contribution to editing the vol-
ume was supported in part by grants (R206R50001 and R206A70001)
from the Javits Program of the U.S. Office of Educational Research and
Improvement.
