Boduch-Grabka and Lev-Ari (2021) showed that so-called “native” British-English speakers judged statements produced by Polish-accented English speakers as less likely to be true than statements produced by “native” speakers and that prior exposure to Polish-accented English speech modulates this effect. Given the real-world consequences of this study, as well as our commitment to assessing and mitigating linguistic biases, we conducted a close replication, extending the work by collecting additional information about participants’ explicit biases towards Polish migrants in the UK. We did not reproduce the original pattern of results, observing no effect of speaker accent or exposure on comprehension or veracity. In addition, the measure of explicit bias did not predict differential veracity ratings for Polish- and British-accented speech. Although the current pattern of results differs from that of the original study, our finding that neither comprehension nor veracity were impacted by accent or exposure condition is not inconsistent with the Boduch-Grabka and Lev-Ari (2021) processing difficulty account of the accent-based veracity judgment effect. We explore possible explanations for the lack of replication and future directions for this work.

暴露和明确的刻板印象对波兰口音英语语音准确性判断的影响：Boduch-Grabka & Lev-Ari (2021) 的预注册紧密复制和扩展

Boduch-Grabka 和 Lev-Ari (2021) 表明，所谓的“母语”英式英语使用者认为波兰口音英语使用者所发表的陈述不如“母语”使用者所发表的陈述更真实，并且之前接触过波兰口音的英语语音调节了这种效果。考虑到这项研究对现实世界的影响，以及我们对评估和减轻语言偏见的承诺，我们进行了密切的复制，通过收集有关参与者对英国波兰移民的明确偏见的更多信息来扩展工作。我们没有重现结果的原始模式，观察到说话者的口音或暴露对理解或准确性没有影响。此外，显性偏见的测量并不能预测波兰口音和英国口音语音的不同准确性评级。尽管当前的结果模式与最初的研究不同，但我们发现理解性和准确性都不受口音或暴露条件的影响，这与 Boduch-Grabka 和 Lev-Ari (2021) 对口音处理难度的解释并不矛盾。基于真实性的判断效果。我们探讨了缺乏重复性的可能解释以及这项工作的未来方向。
