8. Child Witnesses And The Confrontation Clause., Thomas D. Lyon, Julia A. Dente Apr 2012

8. Child Witnesses And The Confrontation Clause., Thomas D. Lyon, Julia A. Dente

Thomas D. Lyon

After the Supreme Court’s ruling in Crawford v. Washington that a criminal defendant’s right to confront the witnesses against him is violated by the admission of testimonial hearsay that has not been cross-examined, lower courts have overturned convictions in which hearsay from children was admitted after child witnesses were either unwilling or unable to testify. A review of social scientific evidence regarding the dynamics of child sexual abuse suggests a means for facilitating the fair receipt of children’s evidence. Courts should hold that defendants have forfeited their confrontation rights if they exploited a child’s vulnerabilities such that they could reasonably …

27. Does Valence Matter? Effects Of Negativity On Children's Early Understanding Of Truths And Lies., Lindsay Wandrey, Jodi A. Quas, Thomas D. Lyon

Early deceptive behavior often involves acts of wrongdoings on the part of children. As a result, it has often been assumed, although not tested directly, that children are better at identifying lies about wrongdoing than lies about other activities. We tested this assumption in two studies. In Study 1, 67 3- to 5-year-olds viewed vignettes in which a character truthfully or falsely claimed to have committed a good or bad act. Children were biased to label claims that the character had committed a good act as the truth and claims that the character had committed a bad act as lies. …

11. Twenty-Five Years Of Interviewing Research And Practice: Dolls, Diagrams, And The Dynamics Of Abuse Disclosure., Thomas D. Lyon

Thomas D. Lyon

A great deal of research in the past 25 years has contributed to our understanding of how best to interview children about suspected maltreatment. The disastrous failures of the highly publicized daycare abuse cases led to a flood of research, initially emphasizing the failures of conventional approaches, and more recently highlighting the potential for eliciting complete and accurate reports.  If a child has disclosed abuse, and is willing to disclose again, we know what to do. Research supports the use of interview instructions, narrative practice rapport building, and the use of open ended questions to elicit and to elaborate on …

PREDATORS AND PROPENSITY: THE PROPER APPROACH FOR DETERMINING THE ADMISSIBILITY OF PRIOR BAD ACTS EVIDENCE IN CHILD SEXUAL ABUSE PROSECUTIONS

Basyle J. Tchividjian

Abstract

The admissibility of prior bad act evidence in child sexual abuse prosecutions oftentimes makes the difference between a guilty and not guilty verdict. Recently, jurisdictions have growingly embraced the admission of such evidence for the purpose of establishing the defendant’s propensity to sexually victimize children. Due to the potentially high prejudicial effect of admitting propensity evidence, it is more critical than ever that courts carefully apply the decisive evidentiary gatekeeper, the probative value balancing test …


26. “How Did You Feel?”: Increasing Child Sexual Abuse Witnesses’ Production Of Evaluative Information., Thomas D. Lyon, Nicholas Scurich, Karen Choi, Sally Handmaker, Rebecca Blank Dec 2011

26. “How Did You Feel?”: Increasing Child Sexual Abuse Witnesses’ Production Of Evaluative Information., Thomas D. Lyon, Nicholas Scurich, Karen Choi, Sally Handmaker, Rebecca Blank

In child sexual abuse cases, the victim’s testimony is essential, because the victim and the perpetrator tend to be the only eyewitnesses to the crime. A potentially important component of an abuse report is the child’s subjective reactions to the abuse. Attorneys may ask suggestive questions or avoid questioning children about their reactions, assuming that children, given their immaturity and reluctance, are incapable of articulation. We hypothesized that How questions referencing reactions to abuse (e.g., “howdid you feel”) would increase the productivity of children’s descriptions of abuse reactions. Two studiescompared the extent to which children provided evaluative content, defined as …
