The power of technology: Examining the effects of digital visual evidence on jurors' processing of trial information

Abstract

SummaryWith the emergence of “electronic courtrooms” in North America, lawyers are increasingly using PowerPoint® to assist with their presentation of case evidence. The current study examined whether evidence complexity and presentation modality influenced participants' comprehension of case evidence and verdict decisions. Participants read a trial transcript from a criminal case that contained DNA evidence, which varied by complexity (simple or complex) and presentation modality (written or PowerPoint®). Participants completed comprehension questions to assess their understanding of the case evidence and rendered a verdict. Results demonstrated that neither the complexity nor the modality of the presented evidence influenced participants' comprehension of the evidence; however, participants who viewed evidence within a PowerPoint® were significantly more likely to render guilty verdicts than those who viewed written evidence. We discuss the theoretical and practical implications of these findings and propose suggestions for future research on the use of digital technology in the courtroom.
