Extensive posttrial protocol analyses are used to obtain data on juror information processing. The representation of the story or stories induced from the case materials (filmed murder trial) are identified and summarized using a Schank and Abelson style causal event chain and goal/plan hierarchy analysis. The structure and content of inferences underlying the causal representation are identified and characterized using Allan Collin's (1979) theory of human plausible reasoning. The adequacy of these schemes in characterizing talk-aloud protocol text is examined for two juror protocols. Figures and six references are supplied. (Author abstract modified)
