This serial was established under the editorship of Dr. Norman R. Willis in 1966. As a result of his editorial
effort and the contributions of many authors, the serial is now recognized as the area's best source of reviews
of behavioral research on mental retardation. From its inception, active research scientists and graduate students
in mental retardation have looked to this serial as a major source of critical reviews of research and theory in
the area. These volumes are required reading for any professional seeking a deeper insight into the behavioral
consequences of intellectual and developmental handicaps.
