54. The Effects Of The Hypothetical Putative Confession And Negatively-Valenced Yes/No Questions On Maltreated And Non-Maltreated Children’S Disclosure Of A Minor Transgression., Stacia N. Stolzenberg, Kelly Mcwilliams, Thomas D. Lyon Sep 2016

54. The Effects Of The Hypothetical Putative Confession And Negatively-Valenced Yes/No Questions On Maltreated And Non-Maltreated Children’S Disclosure Of A Minor Transgression., Stacia N. Stolzenberg, Kelly Mcwilliams, Thomas D. Lyon

Thomas D. Lyon

This study examined the effects of the hypothetical putative confession (telling children “What if I said that [the suspect] told me everything that happened and he wants you to tell the truth?”) and negatively-valenced yes/no questions varying in their explicitness (“Did [toy] break?” vs. “Did something bad happen to the [toy]?”) on 206 4- to 9-year-old maltreated and non-maltreated children’s reports, half of whom had experienced toy breakage and had been admonished to keep the breakage a secret. The hypothetical putative confession increased the likelihood that children disclosed breakage without increasing false reports. The yes/no questions elicited additional disclosures of …


38. Social And Cognitive Factors Associated With Children's Secret-Keeping For A Parent., Heidi M. Gordon, Thomas D. Lyon, Kang Lee Jul 2014

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 May 2014

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 May 2014

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 May 2014

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 Apr 2014

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 …


33. Disclosing Adult Wrongdoing: Maltreated And Non-Maltreated Children’S Expectations And Preferences., Lindsay C. Malloy, Jodi A. Quas, Thomas D. Lyon, Elizabeth C. Ahern Jan 2014

33. Disclosing Adult Wrongdoing: Maltreated And Non-Maltreated Children’S Expectations And Preferences., Lindsay C. Malloy, Jodi A. Quas, Thomas D. Lyon, Elizabeth C. Ahern

Thomas D. Lyon

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 Nov 2013

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 …


32. Eliciting Maltreated And Non-Maltreated Children’S Transgression Disclosures: Narrative Practice Rapport Building And A Putative Confession., Thomas D. Lyon, Lindsay Wandrey, Elizabeth C. Ahern, Robyn Licht, Megan P.Y. Sim, Jodi A. Quas Oct 2013

32. Eliciting Maltreated And Non-Maltreated Children’S Transgression Disclosures: Narrative Practice Rapport Building And A Putative Confession., Thomas D. Lyon, Lindsay Wandrey, Elizabeth C. Ahern, Robyn Licht, Megan P.Y. Sim, Jodi A. Quas

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 Sep 2013

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 …


29. Young Children’S Understanding That Promising Guarantees Performance: The Effects Of Age And Maltreatment., Thomas D. Lyon, Angela D. Evans Jul 2013

29. Young Children’S Understanding That Promising Guarantees Performance: The Effects Of Age And Maltreatment., Thomas D. Lyon, Angela D. Evans

Thomas D. Lyon

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 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 …


11. Report Of The Apsac Task Force On Attachment Therapy, Reactive Attachment Disorder, And Attachment Problems., Mark Chaffin, Rochelle Hanson, Benjamin E. Saunders, Todd Nichols, Douglas Barnett, Charles Zeanah, Lucy Berliner, Byron Egeland, Elana Newman, Thomas D. Lyon, Elizabeth Letourneau, Cindy Miller-Perrin Jan 2006

11. Report Of The Apsac Task Force On Attachment Therapy, Reactive Attachment Disorder, And Attachment Problems., Mark Chaffin, Rochelle Hanson, Benjamin E. Saunders, Todd Nichols, Douglas Barnett, Charles Zeanah, Lucy Berliner, Byron Egeland, Elana Newman, Thomas D. Lyon, Elizabeth Letourneau, Cindy Miller-Perrin

Thomas D. Lyon

Although the term attachment disorder is ambiguous, attachment therapies are increasingly used with children who are maltreated, particularly those in foster care or adoptive homes. Some children described as having attachment disorders  show extreme disturbances. The needs of these children and their caretakers are real. How to meet their needs is less clear. A number of attachment-based treatment and parenting approaches purport to help children described as attachment disordered. Attachment therapy is a young and diverse field, and the benefits and risks of many treatments remain scientifically undetermined. Controversies have arisen about potentially harmful attachment therapy techniques used by a …

8. The Science Of Child Sexual Abuse., Jennifer J. Freyd, Frank W. Putnam, Thomas D. Lyon, Kathryn A. Becker-Blease, Ross E. Cheit, Nancy B. Siegel, Kathy Pezdek

Thomas D. Lyon

Child sexual abuse (CSA) involving sexual contact between an adult (usually male) and a child has been reported by 20% of women and 5 to 10% of men worldwide (1–3). Surveys likely underestimate prevalence because of underreporting and memory failure (4–6). Although official reports have declined somewhat in the United States over the past decade (7), close to 90% of sexual abuse cases are never reported to the authorities (8).


7. Why Child Maltreatment Researchers Should Include Children’S Disability Status In Their Maltreatment Studies., Kathleen Kendall-Tackett, Thomas D. Lyon, Greg Taliaferro Aug 2005

7. Why Child Maltreatment Researchers Should Include Children’S Disability Status In Their Maltreatment Studies., Kathleen Kendall-Tackett, Thomas D. Lyon, Greg Taliaferro

Thomas D. Lyon

Approximately8%of children in the US have disabilities (US Census Bureau, 2002), and these children are more likely to be abused or neglected than their non-disabled peers. The studies that have identified this vulnerability have varied in methodology and sample, and yet the findings have been remarkably consistent. But much work still needs to be done to know the magnitude of the problem, and what professionals can do to help. We are writing to encourage researchers in the child maltreatment field to include children’s disability status in their studies of abuse and neglect. Below is a summary of what …


5. Scientific Support For Expert Testimony On Child Sexual Abuse Accommodation., Thomas D. Lyon May 2002

5. Scientific Support For Expert Testimony On Child Sexual Abuse Accommodation., Thomas D. Lyon

Thomas D. Lyon

Roland Summit's article on child sexual abuse accommodation (CSAA)(Summit, 1983) describes sexually abused children's secrecy, helplessness, entrapment, delayed disclosure, and retraction. The paper is both admired and maligned. On the one hand, it has been hailed as one of the most influential papers ever written on child abuse (Oates & Donnelly, 1997). On the other hand, testimony on accommodation is often dismissed as dangerous pseudoscience" by both commentators and the courts (Summit, 1992).


5. Young Maltreated Children’S Competence To Take The Oath., Thomas D. Lyon, Karen J. Saywitz Dec 1998

5. Young Maltreated Children’S Competence To Take The Oath., Thomas D. Lyon, Karen J. Saywitz

Thomas D. Lyon

Two studies examined I92 maltreated young children's competence to take the oath.  Study I found that despite serious delays in receptive vocabulary, a majority of 5-year-olds correctly identified truthful statements and lies as such and recognized that lying is bad and would make authority figures mad. However, most participants up to 7 years of age could not define "truth" and "lie" or explain the difference between the terms. Four-year-olds were above chance in recognizing the immorality of lying but exhibited a tendency to identify all statements as the "truth. " Study 2 found that 4- and 5-year-olds performed above chance …
