Now you see it, now you don't: Repetition blindness for nonwords. *Journal of Experimental Psychology: Learning Memory and Cognition*, *34*(1), 146–166. **Target of replication.** The finding we are attempting to replicate is a significant repetition blindness (RB) effect for nonwords. A one-way ANOVA of nonword items, using participants as cases and condition as a within-subjects† factor will measure this effect. **A priori replication criteria.** A successful replication would find a significant RB effect for nonwords at *p* < .05. **Materials, data, and report.** Study materials and analysis script can be found in the [materials component][1] of this project. Raw and processed data can be found in the [data component][2]. The [full report][3] and other documents are available in the [files section][4] of this node. **Conclusions.** We failed to replicate the original result. A one-way ANOVA of nonword items, using participants as cases and Condition as a within-subject factor, did not find a significant RB effect, *F*(1, 23) = 1.28, η2(partial) = .051, *p* = .269. We propose that the failure to replicate stems from a floor effect present in both the original and the present study.

It is only a between-subjects factor when *items* are treated as cases. ---------- ![Meta-analysis and forest plot of RB effects for nonwords.][6] Meta-analysis and forest plot of RB effects for nonwords. The forest plot shows Cohen’s d (square icons for individual experiments; central vertices of the diamond for overall data) and 95% confidence intervals (whiskers for individual experiments; horizontal extent of the diamond for overall data). The solid vertical line corresponds to no effect (d = 0), and the dashed vertical line corresponds to the estimated overall effect (d = 1.26). For all experiments, *N* = 24.
