OBJECTIVES Recent virtual court proceedings have seen a range of technological challenges, producing not only trial interruptions but also cognitive interruptions in processing evidence. Very little empirical research has focused on how the subjective experience of processing evidence affects evaluations of trial participants and trial decisions. Metacognitive research shows that the subjective ease or difficulty of processing information can affect evaluations of people, belief in information, and how a given piece of information is weighted in decision making. HYPOTHESES We hypothesized that when people experienced technological challenges (e.g., poor audio quality) while listening to eyewitness accounts, the difficulty in processing evidence would lead them to evaluate a witness more negatively, influence their memory for key facts, and lead them to weigh that evidence less in final trial judgments. METHOD Across three experiments (total N = 593), participants listened to audio clips of witnesses describing an event, one presented in high-quality audio and one presented in low-quality audio. RESULTS When people heard witnesses present evidence in low-quality audio, they rated the witnesses as less credible, reliable, and trustworthy (Experiment 1, d = 0.32; Experiment 3, d = 0.55); had poorer memory for key facts presented by the witness (Experiment 2, d = 0.44); and weighted witness evidence less in final guilt judgments (Experiment 3, ηp² = .05). CONCLUSION These results show that audio quality influences perceptions of witnesses and their evidence. Because these variables can contribute to trial outcomes, audio quality warrants consideration in trial proceedings. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

虚拟法庭的声音和可信度:音频质量低导致对证人的评价较差,证据权重较低。

目标 最近的虚拟法庭诉讼程序遇到了一系列技术挑战,不仅造成审判中断,而且在处理证据时也造成认知中断。很少有实证研究关注处理证据的主观体验如何影响对试验参与者的评价和试验决定。元认知研究表明,处理信息的主观难易程度会影响人们对信息的评价、对信息的信念,以及给定信息在决策中的权重。假设 我们假设,当人们在聆听目击者的叙述时遇到技术挑战(例如,音频质量差)时,处理证据的困难会导致他们对证人的评价更加消极,影响他们对关键事实的记忆,并引导他们在最终审判判决中减少对证据的权衡。方法 在三个实验中(总共 N = 593),参与者听取了目击者描述事件的音频片段,一个以高质量音频呈现,一个以低质量音频呈现。结果当人们听到证人以低质量的音频提供证据时,他们认为证人的可信度、可靠性和可信度较低(实验 1,d = 0.32;实验 3,d = 0.55);对证人提供的关键事实的记忆较差(实验 2,d = 0.44);在最终有罪判决中加权证人证据较少(实验 3,ηp² = .05)。结论 这些结果表明,音频质量会影响证人及其证据的感知。由于这些变量会影响审判结果,因此在审判程序中需要考虑音频质量。
