Computer Generated Exhibits (CGE) are frequently deployed in legal contexts under the rubric of demonstrative evidence, i.e. to facilitate juror comprehension. However, a number of legal and academic commentators have suggested that the nature of the computerised moving image could exert undue prejudice on decision makers, e.g. judge and/or jury. The current study aimed to assess the manipulation of vehicle characteristics (make and colour) when a road traffic accident was presented in the format of a computer generated animation (CGA). In experiment 1, two groups of subjects watched two different makes of car, a Range Rover Sport and a Volkswagen Touran in a black-and-white format; no significant differences emerged over vehicle model with regards to vehicle speed or overall responsibility for the accident. Experiment 2 presented the same vehicles to four groups of participants in full colour, with the cars in contrasting red or beige; significant differences emerged with regards to culpability for vehicle make only. The findings could have implications for the format and style of CGE used in legal settings.
