The present study evaluated the possibility of correlation between the results of the Language Processing Test (LPT3) and the Promoting the Emergence of Advanced Knowledge Relational Training System – Equivalence Module (PEAK-E). Thirteen participants with language disabilities were administered both assessments, and results indicated a significant linear correlation (r = 0.9268, p < 0.1) between the two measures. Implications for a greater understanding of human language and cognition are discussed.
