2. Gold points out that we included six to seven subjects with IQs lower than 75 and raises the issue of comparing WISC and WAIS scores among subjects termed "intellectually limited." The cutoff for "intellectually limited" is usually a full-scale IQ lower than 70. We have, therefore, reexamined our data in subjects whose full-scale IQs were lower than 70. During the follow-up period, 50% of these subjects showed improved IQ, and 50% showed a decline. There were no significant differences between IQs at time 1 and time 2 in the subjects whose full-scale IQs were lower than 70, a finding similar to the findings for the group overall. Thus, there is no substance to Dr. Gold's argument.
