This information was not explicitly stated in either article, but the sample and community description makes it clear that the participants of these studies are the same people, though the sample sizes differ slightly (ns = 85 and 86). However, this redundancy did not produce any analysis problems because the correlation matrix in the Grigorenko et al. (2001) article was not positive definite.
The duplication of data across articles and the non-positive definite dataset have never been fully explained. In light of Sternberg's history of self-plagiarism (see link below), this is troubling.
