Farrell and Lewandowsky (2008) argued that the temporal context model (TCM; Howard & Kahana, 2002) cannot explain nonmonotonicities in the contiguity effect seen at extreme lags. However, TCM actually predicts these nonmonotonicities to the extent that end-of-list context persists as a retrieval cue during recall and to the extent that end-of-list context generates a recency effect. We show that the observed nonmonotonicity in the contiguity effect interacts with the recency effect, as predicted by TCM. In conditions, such as immediate and continualdistractor free recall, that exhibit strong recency, one observes more prominent nonmonotonicities in the contiguity effect than in conditions, such as delayed free recall, that attenuate recency. The nonmonotonicities in the contiguity effect at extreme lags, and the interactions between recency and contiguity, result from the role of end-of-list context as a retrieval cue in TCM.
