**Target of replication.** The key effect in experiment four, demonstrating an interaction between stimulus quality and word frequency during a task where participants categorized words and nonwords, F(1, 31) = 5.17, p = .03.
**A priori replication criteria.** A successful replication would find a significant interaction between stimulus quality and word frequency where there is "a larger frequency effect for degraded words."
