Abstract
Despite increases in bandwidth, most video conferencing equipment delivers a sub-optimal quality signal. Artifacts caused by video compression and other technological constraints lead to the distortion of subtle communicative cues. This study explores the effects of such video degradation on individuals' ability to detect whether others are lying or telling the truth. Forty-two participants observed mock job interviews presented in High-Quality Audio, High-Quality Audio + High-Quality Video, and High-Quality Audio + Reduced Frame Rate (3 fps) Video. The interviews contained a mix of truthful and deceptive responses, and participants attempted to distinguish the two. Performance in the Reduced Frame Rate condition was significantly worse than in the High Quality Video condition. These findings have implications for both the development and implementation of video-conferencing technology.
