**Original citation.** Colzato, L.S., Bajo, M.T., van den Wildenberg, W., Paolieri, D., Nieuwenhuis, S., La Heij, W., & Hommel, B. (2008). *Journal of Experimental Psychology: Learning, Memory, and Cognition, 34*(2), 302-312. **Target of replication.** We seek to replicate the finding that bilinguals show a more pronounced attentional blink than monolinguals, F(3,93) = 5.23, p = .002; specifically, bilingual participants were significantly less successful than monolinguals at reporting the T2 target when it lagged a successfully identified T1 target by 2 items (i.e., at lag 3). **A priori replication criteria.** We expected to find that for all participants, on trials when T1 was correctly identified there would be high T2 accuracy for lag 1, which would drop at lag 3 (i.e., the “attentional blink”) and then increase again with increasing lag. We also expected to see that bilinguals would show a larger drop at lag 3 than monolinguals (i.e., a greater attentional blink). We planned to conduct an additional t-test to compare conditional T2 performance between groups at lag 3. In the planned replication, all participants were resident in and tested in London. In the original study, monolingual participants were resident in and tested in Spain and bilingual participants were resident in and tested in the Netherlands. Monolingual participants in the planned replication were fluent in English; bilingual participants in the planned replication were fluent in English and any second language. This is different to the original study where all monolingual participants were fluent in Spanish and bilingual participants were fluent in Dutch and either English or German. We discussed the implication of this difference for the results with Dr. Colzato, who indicated that while it could potentially impact the results, she supported this extension based on her work as a replication and looked forward to the results (see author correspondence).
