**Target of replication:** Researchers seek to replicate study number two. We particularly focus on the finding that low contingency trials produce more errors than medium contingency trials, t(94)=1.929, p=.028, indicating that there is greater response interference when a trial predicts the wrong answer than a trial that makes no prediction.
