**Target of replication.**
The result we have selected as our target for replication is the finding that instructing participants to group items induces a temporal gap between the groups both when trying to recall the order of the items and when trying to recall the timing of the items.
**A priori replication criteria.**
A successful replication would find the presence of an interaction in a repeated-measures, 2
(grouped vs. ungrouped) x 6 (serial position) ANOVA to determine if grouping had any significant effect on subjects’ latencies

**Conclusions.**
The present replication of Study 2 from Farrell (2008) successfully replicated the original finding: that asking participants to group stimuli alters the timing they report, even when subjects are asked to report timing faithfully. The confirmatory analysis revealed a significant interaction between grouping instruction and serial position, as well as a
significant difference in the deviations of the fourth latency from the predictions of a polynomial fit in the ungrouped and grouped conditions.
