요약Amid declining public confidence in law enforcement, particularly among Black Americans, and increased visibility of violent police interactions via social media, scholarly attention has turned to racial disparities in police-community relations. Despite growing research, linguistic bias remains underexamined. Existing studies show that non-native speakers of African American English (AAE) overestimate their comprehension, and court transcriptionists demonstrate low accuracy when transcribing AAE. Misunderstandings and negative perceptions of AAE have been documented in courtroom settings, with speakers viewed as less credible and more criminally culpable. Given that Black Americans are disproportionately subjected to police stops, questioning, and force, linguistic bias may critically contribute to disparate outcomes. This study uses a matched-guise design to evaluate police officers' comprehension and perceptions of AAE speakers. Thirty-one Midwest police officers listened to identical speakers using either AAE or Mainstream American English (MAE) and completed comprehension questions and social perception ratings. Results revealed significant comprehension disparities: officers demonstrated 12.9 percentage points lower accuracy for AAE speakers (62.4%) versus MAE speakers (75.3%), confirmed through paired t-tests (p = .003), non-parametric tests (p = .007), and mixed-effects modeling (OR = 1.97, p = .005). Exploratory analyses of the predominantly White (81%) and male (74%) sample revealed demographic associations with comprehension performance, including a gender effect favoring female officers and age/experience effects associated with lower AAE comprehension; however, the small, homogeneous sample limits conclusions about demographic moderation, warranting replication with larger, more diverse samples. Regarding perceptions, composite analyses showed officers rated AAE speakers significantly more negatively on negative stereotype dimensions (p = .046, d = 0.37) and marginally less positively on positive traits (p = .076), with bias concentrated on criminality and aggression. Qualitative interviews revealed officers identified fear of retaliation and community stigma as primary barriers to cooperation. These findings demonstrate that both comprehension deficits and selective perceptual biases could impair police-community interactions, highlighting the need for communication training, implicit bias training addressing AAE-criminal associations, and systemic reforms addressing linguistic barriers.
