The reliability of confessions is subject to a variety of factors, some of which give rise to expert testimony. To the degree that prosecutors construe the determination of reliability as an objective standard, they may attempt to bar testimony. Moreover, when the testimony is theoretical rather than clinical, there are additional challenges. Depending on jurisdiction, the admissibility of expe...

Research Findings: To test children’s use of testimony of others, 3 – 9 years (N = 227) made judgments about a potential peer transgression in which the intentions of the protagonist were ambiguous, after hearing two different forms of testimony.

Recent work on testimony and the norms of assertion considers cases of expert testimony.
