(A) Non-demented elderly individuals with and without HA learned at the same speed during the learning phases of our acquired equivalence task. (B) In the testing phase, both groups continued to perform well on previously-learned (old) discriminations. However, the HA group was significantly worse at transferring to novel (new) pairs, indicating they had failed to learn the acquired equivalence during the earlier phases.
