【 摘 要 】

The importance of replication in psychology, and science more broadly, cannot be overstatedgiven the current state of the literature. The Open Science Collaboration (2015) attempted toreplicate 100 studies in three top psychology journals and found that only 36% of effects werereplicated. Given this alarmingly low number of successful replications, it is imperative to ensurethat when attempting a replication that task parameters and environmental conditions be as similaras possible to the original study in order to determine the reliability and strength of a given effect.Recently, Goldsmith and Morton (2018) claimed a “failed replication” of a study by Grundy et al.(2017) showing that monolinguals were more affected by the influence of the previous trial oncurrent trial performance than bilinguals during a flanker task. The result across three experimentsin the original study was that monolinguals had larger sequential congruency effects (SCE; Grattonet al., 1992) than bilinguals in both the behavioral and electrophysiological outcomes. However,the Goldsmith and Morton study that did not replicate this pattern differed from the originalexperiments in several ways.
