Foreign language can either enhance decision-making by triggering more deliberation or worsen it due to cognitive overload. We tested these two hypotheses in one response bias: acquiescence. In three experiments, 413 participants made dichotomous decisions about whether 100 personality traits described them or not. Participants showed more acquiescence in a foreign language (vs. native), giving more certifying responses when deciding on known traits. Reaction time results suggest that a foreign language particularly impacts rejection more than certification of their comprehension. These findings support the cognitive overload hypothesis and provide valuable insights for the influence of language on response bias.

揭示外语对默认的作用

外语可以通过引发更多的深思熟虑来增强决策能力，也可以因认知超载而使决策能力恶化。我们在一种反应偏差中测试了这两个假设：默许。在三项实验中，413 名参与者对 100 种人格特质是否描述了自己做出了二分决定。参与者对外语（相对于母语）表现出更多的默许，在决定已知特征时给出更多的证明性反应。反应时间结果表明，外语对拒绝的影响比对其理解力的认证影响更大。这些发现支持认知超载假说，并为语言对反应偏差的影响提供了有价值的见解。
