Accentism on Trial: Categorization/Stereotyping and Implicit Biases Predict Harsher Sentences for Foreign-Accented Defendants

In this study, participants were presented with two tasks: the Implicit Association Test (IAT), and a mock trial task. In both tasks, the auditory stimuli were produced by native or foreign-accented speakers, and presented either free of noise or mixed with background white noise, to estimate the role of processing fluency on jurors' appraisals. In the IAT, participants showed positive implicit biases toward native speech, and negative implicit biases toward foreign-accented speech. In the mock trial task, participants gave much harsher sentences to the foreign-accented than native defendant, but only when defendants' statements were free of noise. Moreover, we found that participants' implicit biases were a relevant predictor of the sentences they gave to the defendants. Our results suggest that categorization/stereotyping is the main mechanism responsible for the effect of defendants' accents on jurors' appraisals, and that members of an estimated group who violate social norms are punished more severely.
