40. Question Types, Responsiveness And Self-Contradictions When Prosecutors And Defense Attorneys Question Alleged Victims Of Child Sexual Abuse, Samantha J. Andrews, Michael E. Lamb, Thomas D. Lyon
Thomas D. Lyon
We examined 120 trial transcripts of 6- to 12-year-old children testifying to sexual abuse. Age and attorney role were analyzed in relation to question types, children’s responsiveness, and self-contradiction frequency. A total of 48,716 question-response pairs were identified. Attorneys used more closed-ended than open-ended prompts. Prosecutors used more invitations (3% vs. 0%), directives and option-posing prompts than defence attorneys, who used more suggestive prompts than prosecutors. Children were more unresponsive to defence attorneys than to prosecutors. Self-contradictions were identified in 95% of the cases. Defence attorneys elicited more self-contradictions than prosecutors, but nearly all prosecutors (86%) elicited at least one …

39. Young Children’S Difficulty With Indirect Speech Acts: Implications For Questioning Child Witnesses, Angela D. Evans, Stacia N. Stolzenberg, Kang Lee, Thomas D. Lyon
Thomas D. Lyon
Prior research suggests that infelicitous choice of questions can significantly underestimate children’s actual abilities, independently of suggestiveness. One possibly difficult question type is indirect speech acts such as “Do you know…” questions (DYK, e.g., “Do you know where it happened?”). These questions directly ask if respondents know, while indirectly asking what respondents know. If respondents answer “yes,” but fail to elaborate, they are either ignoring or failing to recognize the indirect question (known as pragmatic failure). Two studies examined the effect of indirect speech acts on maltreated and non-maltreated 2- to 7-year-olds’ post-event interview responses. Children were read a story …

38. Social And Cognitive Factors Associated With Children's Secret-Keeping For A Parent., Heidi M. Gordon, Thomas D. Lyon, Kang Lee
Thomas D. Lyon
This study examined children’s secret-keeping for a parent and its relation to trust, theory of mind, secrecy endorsement, and executive functioning (EF). Children (N = 107) between 4 and 12 years of age participated in a procedure wherein parents broke a toy and asked children to promise secrecy. Responses to open-ended and direct questions were examined. Overall, secret-keeping increased with age and promising to keep the secret was related to fewer disclosures in open-ended questioning. Children who kept the secret in direct questioning exhibited greater trust and better parental ratings of EF than children who disclosed the secret. Findings highlight …

37. Attorneys' Questions And Children's Productivity In Child Sexual Abuse Criminal Trials., J. Zoe Klemfuss, Jodi A. Quas, Thomas D. Lyon
Thomas D. Lyon
We investigated the links between questions child witnesses are asked in court, children’s answers, and case outcome. Samples of acquittals and convictions were matched on child age, victim–defendant relationship, and allegation count and severity. Transcripts were coded for question types, including a previously under-examined type of potentially suggestive question, declarative questions. Children’s productivity was conceptualized in a novel way by separating new from repeated content and by adjusting the definition based on the linguistic demands of the questions. Attorneys frequently used declarative questions, and disconcertingly, attorneys who used these and other suggestive questions more frequently were more likely to win …

36. Evidence Summarized In Attorneys' Closing Arguments Predicts Acquittals In Criminal Trials Of Child Sexual Abuse., Stacia N. Stolzenberg, Thomas D. Lyon
Thomas D. Lyon
Evidence summarized in attorney’s closing arguments of criminal child sexual abuse cases (N = 189) was coded to predict acquittal rates. Ten variables were significant bivariate predictors; five variables significant at p < .01 were entered into a multivariate model. Cases were likely to result in an acquittal when the defendant was not charged with force, the child maintained contact with the defendant after the abuse occurred, or the defense presented a hearsay witness regarding the victim’s statements, a witness regarding the victim’s character, or a witness regarding another witnesses’ character (usually the mother). The findings suggest that jurors might …

35. Interviewing Children., Thomas D. Lyon
Thomas D. Lyon
This article reviews best practice for interviewing child witnesses. In most officially recognized abuse cases, the child previously disclosed abuse, making it possible to elicit disclosures without asking closed-ended questions. Interviewers nevertheless overuse closed-ended questions, which lead to short unelaborated responses, privilege the limited perspective of the interviewer, maximize the potential for linguistic difficulties, increase children’s tendency to guess, and risk response biases. Interviewers can avoid closed-ended questions through narrative practice, in which interviewers ask children to narrate a recent innocuous event before introducing the abuse topic; cued invitations, in which interviewers repeat details reported by children and ask for …

34. Disclosure Suspicion Bias And Abuse Disclosure: Comparisons Between Sexual And Physical Abuse., Elizabeth B. Rush, Thomas D. Lyon, Elizabeth C. Ahern, Jodi A. Quas
Thomas D. Lyon
Prior research has found that children disclosing physical abuse appear more reticent and less consistent than children disclosing sexual abuse. Although this has been attributed to differences in reluctance, it may also be due to differences in the process by which abuse is suspected and investigated. Disclosure may play a larger role in arousing suspicions of sexual abuse, while other evidence may play a larger role in arousing suspicions of physical abuse. As a result, children who disclose physical abuse in formal investigations may be doing so for the first time, and they may be more reluctant to provide details …

9. Children's Memory For Conversations About Sexual Abuse: Legal And Psychological Implications., Thomas D. Lyon, Stacia N. Stolzenberg
Thomas D. Lyon
The legal and psychological literature on children’s testimony in child sexual abuse cases has largely focused on whether children are allowed to testify, how children testify, and what happens after they do. Those concerned about false convictions have emphasized the benefits of mechanisms to exclude children’s testimony that is unreliable because of pre-trial influence or developmental immaturity1 and the utility of expert testimony on children’s suggestibility. Those concerned about false acquittals have argued for eliminating barriers to receiving children’s testimony, the benefits of setting up special devices (such as screens or closed-circuit television) for receiving testimony, and the utility of …

Little is known about the process by which children disclose adult wrongdoing, a topic of considerable debate and controversy. In the current study, we investigated children’s evaluations of disclosing adult wrongdoing by focusing on children’s preferences for particular disclosure recipients and perceptions of the consequences of disclosure in hypothetical vignettes. We tested whether children thought that disclosure recipients would believe a story child as a truth teller and what actions the recipients would take against the ‘‘instigator’’ who committed the transgression. Maltreated and non-maltreated 4- to 9-year-olds (N = 235) responded to questions about vignettes that described a parent’s or …

12. Interviewing Victims And Suspected Victims Who Are Reluctant To Talk., Irit Irit Hershkowitz, Michael E. Lamb, Thomas D. Lyon
Thomas D. Lyon
Most professionals know that many alleged victims do not disclose abuse when formally interviewed and that disclosure is affected by a variety of factors, among which the relationship between suspects and children appears to be especially important (see Pipe, Lamb, Orbach, & Cederborg, 2007, for reviews). Children––especially boys and preschoolers––are hesitant to report abuse by parents and guardians, particularly when sexual rather than physical abuse is suspected. For example, Pipe, Lamb, Orbach, Stewart, Sternberg, and Esplin (2007) reported that only 38% of the preschoolers interviewed disclosed sexual abuse by a parent even when the allegations were independently substantiated by corroborative …

Thomas D. Lyon
This study tested the effects of narrative practice rapport building (asking open-ended questions about a neutral event) and a putative confession (telling the child an adult “told me everything that happened and he wants you to tell the truth”) on 4- to 9-year-old maltreated and nonmaltreated children’s reports of an interaction with a stranger who asked them to keep toy breakage a secret (n = 264). Only one third of children who received no interview manipulations disclosed breakage; in response to a putative confession, one half disclosed. Narrative practice rapport building did not affect the likelihood of disclosure. Maltreated children …

31. How Attorneys Question Children About The Dynamics Of Sexual Abuse And Disclosure In Criminal Trials., Stacia N. Stolzenberg, Thomas D. Lyon
Thomas D. Lyon
Little is known about how the dynamics of sexual abuse and disclosure are discussed in criminal court. We examined how attorneys ask child witnesses in sexual abuse cases (N #1; 72, 6–16 years of age) about their prior conversations, both with suspects and with disclosure recipients. Prosecutors’ questions were more open-ended than defense attorneys, but most questions asked by either attorney were yes/no questions, and children tended to provide unelaborated responses. Prosecutors were more inclined to ask about children’s prior conversations with suspects than defense attorneys, but focused on the immediate abuse rather than on grooming behavior or attempts to …

Two studies, with 102 nonmaltreated 3- to 6-year-old children and 96 maltreated 4- to 7-year-old children, examined children’s understanding of the relative strengths of “I promise,” “I will,” “I might,” and “I won’t,” to determine the most age-appropriate means of eliciting a promise to tell the truth from child witnesses. Children played a game in which they chose which of 2 boxes would contain a toy after hearing story characters make conflicting statements about their intent to place a toy in each box (e.g., one character said “I will put a toy in my box” and the other character said …

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
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. …

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 …

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
Thomas D. Lyon
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 …

Research examining children’s temporal knowledge has tended to utilize brief temporal intervals and singular, neutral events, and is not readily generalizable to legal settings in which maltreated children are asked temporal questions about salient, repeated abuse that often occurred in the distant past. To understand how well maltreated children can describe temporal location and numerosity of documented, personal experiences, we assessed 167 6- to 10-year-old maltreated children’s temporal memory for changes in their living arrangements and prior visits to court. Small percentages of children were capable of providing exact temporal location information (age, month, or season) regarding their first or …

We describe a Bayesian approach to evaluating children’s abuse disclosures and review research demonstrating that children’s disclosure of genital touch can be highly probative of sexual abuse, with the probative value depending on disclosure spontaneity and children’s age. We discuss how some commentators understate the probative value of children’s disclosures by: confusing the probability of abuse given disclosure with the probability of disclosure given abuse, assuming that children formally questioned about sexual abuse have a low prior probability of sexual abuse, misstating the probative value of abuse disclosure, and confusing the distinction between disclosure and nondisclosure with the dstinction between …

Truth-lie competency, which concerns the child's understanding of the difference between truth and lies and the importance of telling the truth, can be demonstrated by asking the child whether simple statements are the truth, and by asking the child to promise to tell the truth. Tests of children's truth-lie competency do not predict honesty, but eliciting a child's promise to tell the truth does increase honesty.

This study examined children’s accuracy in response to truth–lie competency questions asked in court.The participants included 164 child witnesses in criminal child sexual abuse cases tried in Los AngelesCounty over a 5-year period (1997–2001) and 154 child witnesses quoted in the U.S. state and federalappellate cases over a 35-year period (1974 –2008). The results revealed that judges virtually never foundchildren incompetent to testify, but children exhibited substantial variability in their performance based on question-type. Definition questions, about the meaning of the truth and lies, were the most difficultlargely due to errors in response to “Do you know” questions. Questions about …

This study examined the origins of children’s ability to make consciously false statements, a necessary component of lying. Children 2 to 5 years of age were rewarded for claiming that they saw a picture of a bird when viewing pictures of fish. They were asked outcome questions (“Do you win/lose?”), recognition questions (“Do you have a bird/fish?”), and recall questions (“What do you have?”), which were hypothesized to vary in difficulty depending on the need for consciousness of falsity (less for outcome questions) and self-generation of an appropriate response (more for recall questions). The youngest children (21⁄2 to 31⁄2 years …

Children, if questioned in a supportive manner, are capable of providing enormous amounts of productive information in response to open-ended questions. The irony is that many direct and suggestive methods once thought necessary to overcome abused children's reluctance to disclose abuse have been found counterproductive in two ways: they minimize the number of details in true allegations at the same time that they increase the risk of false allegations.

A total of two hundred ninety-nine 4- to 9-year-old maltreated and nonmaltreated children of comparable socioeconomic status and ethnicity judged whether children should or would disclose unspecified transgressions of adults (instigators) to other adults (recipients) in scenarios varying the identity of the instigator (stranger or parent), the identity of the recipient (parent, police, or teacher), and the severity of the transgression (‘‘something really bad’’ or ‘‘something just a little bad’’). Children endorsed more disclosure against stranger than parent instigators and less disclosure to teacher than parent and police recipients. The youngest maltreated children endorsed less disclosure than nonmaltreated children, but …

The research supports the proposition that CSA victims often delay disclosure or fail altogether to disclose abuse and that delays and nondisclosure are most common among children abused by a familiar person, especially a family member living in the child's household. The implications of the research are that inconsistencies and recantations in children's reports may be due to reluctance rather than a false allegation.

Objectives: The purpose of the study was to examine differences between maltreated and nonmaltreated children’s ability to differentiate emotionally evocative fantastic and real events.
Methods: Four- and 5-year-old (n = 145) maltreated and nonmaltreated children viewed images depicting positive and negative fantastic and real events and reported whether the events could occur in real life and how the images made them feel. Children also completed a measure of verbal ability.
Results: Maltreated children were more accurate than nonmaltreated children in stating that negative real events could occur, but less accurate in stating that frightening fantastic events …

This book chapter reviews 14 retrospective surveys inquiring into respondent’s child abuse experiences and whether they ever disclosed abuse as children. I discuss the advantages of retrospective surveys (representativeness, reduced likelihood of false allegations, reduced suspicion bias). However, I also emphasize the likelihood of survey reluctance, and explain how this biases upwards estimates of abuse victims’ prior disclosure. If respondents who previously disclosed abuse are more likely to acknowledge abuse to a surveyor than respondents who never previously disclosed abuse, respondents who acknowledge abuse are disproportionately likely to be those who have previously disclosed. Difficulties notwithstanding, the research supports the …
