This research examined the effects of several versions of capital penalty phase instructions on juror comprehension. Study One documented the impact of California's recently implemented "plain language" instruction. It showed that although the new instruction has clear advantages over the previous version, significant comprehension problems remain. Study Two evaluated several modified instructions designed to enhance comprehension. Participants heard either a standard patterned instruction or one of two alternatives-a psycholinguistically improved instruction, or a "pinpoint" instruction using case-related facts to illustrate key terms-in a simulated death penalty sentencing phase. Persons who heard modified instructions demonstrated higher levels of comprehension on virtually every measure as compared to those in the standard instruction condition.

Extraneous neuroscience information improves ratings of scientific explanations, and affects mock juror decisions in many studies, but others have yielded little to no effect. To establish the magnitude of this effect, we conducted a random-effects meta-analysis using 60 experiments from 28 publications. We found a mild but highly significant effect, with substantial heterogeneity.

Legal attitudes, religion, and attributions relate to insanity defense attitudes and legal decisions in insanity cases. Religious fundamentalism has consistently predicted punitiveness associated with insanity; however, the current research focuses on moral disengagement as an explanatory link in the fundamentalist and insanity chain. Additional exploratory interests examined how defendants' perceived proximity to jurors might act as a potential moderator.

When children testify in cases of child sexual abuse (CSA), they often provide minimal responses to attorneys' questions. Thus, how attorneys ask questions may be particularly influential in shaping jurors' perceptions and memory for case details. This study examined mock jurors' perceptions after reading an excerpt of a CSA trial transcript.

This research builds on James Ost's research investigating whether laypeople's beliefs align with those of experts. Recent studies that examined the relationship between high-confidence eyewitness identifications and accuracy proposed that the mechanism underlying this relationship may be based on a knowledge-conditional model. According to this model, the accuracy of a confidence judgment depends on knowledge about factors that affect memory accuracy.

Evidence presented within a courtroom should be clear so that the members of the jury can understand it. The presentation of distressing images, such as human remains, can have a negative effect on the jury since photographic images may evoke emotional responses. Therefore, it is important to understand how other visual mediums may improve comprehension, bias, or distress individuals.
