Roger Ratcliff

Psychologist whose 1990 Psychological Review paper, "Connectionist Models of Recognition Memory: Constraints Imposed by Learning and Forgetting Functions," independently replicated McCloskey & Cohen's catastrophic-interference finding — per French's 1999 review, "for vectors of different sizes and for networks of various types." That makes him the third of the three founding authors the vault treats as the ML side of the catastrophic-forgetting/organizational-forgetting bridge-check.

Known to the vault so far only through French's summary of his replication, not through a direct read of his own paper — and not yet queried against Semantic Scholar's citation graph at all, unlike the other two founding authors. His half of the bridge-check remains an open lead, not a checked gap; see question-verify-catastrophic-organizational-forgetting-citation-lineage.
