The study investigated how different presentation modes (live vs. video) affected observers’ perception, veracity assessments and memory of children’s appearance and their statements. Six children experienced an event and eight children learned about the event by hearsay. Two weeks later the children testified about the event as if they had all experienced it. Mock jurors (N =136) viewed the children’s testimonies either live (N =68) or on video (N =68), and rated their perception and credibility of the children’s statement and appearance. In addition, their memory of the children’s statement was examined. Live observers rated the children’s statements as being more convincing than did video observers. The observers rated the lying children as having to think harder than the truth telling children. Moreover, the overall deception detection performance was 59.6%. Live observers (but not video observers) were better than chance in assessing veracity. Live observers believed they had a better memory of the children’s statements and they also showed a significantly better memory performance than video observers
