In the landmark case Miranda v. Arizona (1966), the United States Supreme Court determined that custodial suspects must be informed of their rights against self-incrimination. The current study investigates the effects of mode of advisement and situational stress on Miranda warning comprehension by using a mock crime study design in which participants attempted to steal a watch from a Plexiglas case. The effects of four different modes of advisement (oral, written, combined/passive, and combined/active) were tested on 115 undergraduate students from the University of North Texas. A one-way ANOVA found a significant difference in Miranda comprehension based on modality. However, situational stress was not found to significantly affect comprehension.
