Doctoral Dissertation Research: The Effect of Computer Displays on Comprehension, Memory and Decision-Making in Court

这项研究提出了一个系统的，理论的，和应用的因素，应考虑确定是否计算机生成的动画是更偏见或证明比其他传统形式的演示媒体（例如，口头证词和图表）。虽然一些实验者专门研究了计算机显示器对受试者决策的影响，但只有少数人使用理论来指导他们的研究，而且迄今为止还没有科学家在一项研究中研究过所有三种沟通渠道（计算机显示器，静态视觉图形和没有视觉辅助的口头演示）之间的差异。本研究的主要目的是确定EELM模型（ELM）的理论严谨性。 该模型的两个关键假设是阐述-增强假设和阐述-破坏假设。具体而言，精心制作-增强假说将提供有关计算机显示器的可能证明效果的信息，而对精心制作-破坏假说的支持将提供有关这种呈现模式的可能偏见效果的信息。拟议的实验设计将作为这两个假设的关键测试，因为它将测试一个滑动和下降的计算机显示器是否增强或破坏信息的论点的阐述。此外，还将评估呈现方式对记忆、理解和决策的影响。因此，该项目不仅吸引社会科学，传播和教育学者，而且对法律，科学和技术的应用社区具有更广泛的影响。

This research presents a systematic, theoretical, and applied examination of factors that should be considered when determining whether a computer-generated animation is more prejudicial or probative than other traditional forms of presentation media (e.g., oral testimony and diagrams). Although some experimenters have specifically examined the effects of computer displays on subjects' decision-making, only a few have used theory to inform their research, and no scientist to date has examined differences between all three channels of communication (computer display, still visual graphics, and an oral presentation without visual aids) in a single study. The main purpose of this research is to determine the theoretical rigor of Elaboration Likelihood Model (ELM). Two key hypotheses underlying this model are the elaboration-enhancement hypothesis and the elaboration-disruption hypothesis. Specifically, the elaboration-enhancement hypothesis would provide information regarding the possible probative effects of a computer display while support for the elaboration-disruption hypothesis would provide information regarding the possible prejudicial effects of such a presentation mode. The proposed experimental design will serve as a critical test of both these hypotheses in that it will test whether or not a slip-and-fall computer display enhances or disrupts elaboration of the message's arguments. Additionally, the effects of mode of presentation on one's memory, comprehension, and decision-making will be assessed. Thus, this project appeals not only to social science, communication, and education scholars, but also has broader implications for the applied communities of law, science, and technology.
