23. Assessing Children’S Competency To Take The Oath In Court: The Influence Of Question Type On Children’S Accuracy., Angela D. Evans, Thomas D. Lyon Dec 2010

23. Assessing Children’S Competency To Take The Oath In Court: The Influence Of Question Type On Children’S Accuracy., Angela D. Evans, Thomas D. Lyon

Thomas D. Lyon

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 …


22. Young Children’S Emerging Ability To Make False Statements., Thomas D. Lyon, Elizabeth C. Ahern, Jodi A. Quas Apr 2010

22. Young Children’S Emerging Ability To Make False Statements., Thomas D. Lyon, Elizabeth C. Ahern, Jodi A. Quas

Thomas D. Lyon

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 …


14. Investigative Interviewing Of The Child., Thomas D. Lyon Feb 2010

14. Investigative Interviewing Of The Child., Thomas D. Lyon

Thomas D. Lyon

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.


21. Children’S Reasoning About Disclosing Adult Transgressions: Effects Of Maltreatment, Child Age, And Adult Identity., Thomas D. Lyon, Elizabeth C. Ahern, Lindsay A. Malloy, Jodi A. Quas Feb 2010

21. Children’S Reasoning About Disclosing Adult Transgressions: Effects Of Maltreatment, Child Age, And Adult Identity., Thomas D. Lyon, Elizabeth C. Ahern, Lindsay A. Malloy, Jodi A. Quas

Thomas D. Lyon

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 …


13. Interviewing Children., Thomas D. Lyon Nov 2009

13. Interviewing Children., Thomas D. Lyon

Thomas D. Lyon

There is sufficient empirical evidence and consensus to begin to build guidelines, including the interview structure, setting, interviewer demeanor, children's reluctance and suggestibility, rapport development, narrative practice, introducing the topic of abuse, avoiding concepts that confuse children, instructions to children, phrasing of questions, evidence-based strategies for eliciting details, and multiple interviews.


12. Disclosure Of Child Sexual Abuse., Thomas D. Lyon, Elizabeth C. Ahern Oct 2009

12. Disclosure Of Child Sexual Abuse., Thomas D. Lyon, Elizabeth C. Ahern

Thomas D. Lyon

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.


20. Maltreated And Non-Maltreated Children’S Evaluations Of Emotional Fantasy., Nathalie Carrick, Thomas D. Lyon, Jodi A. Quas Jan 2009

20. Maltreated And Non-Maltreated Children’S Evaluations Of Emotional Fantasy., Nathalie Carrick, Thomas D. Lyon, Jodi A. Quas

Thomas D. Lyon


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 …


10. Witnesses, Children As Legal., Thomas D. Lyon Dec 2008

10. Witnesses, Children As Legal., Thomas D. Lyon

Thomas D. Lyon

Child witnesses present challenges for both law and psychology. The question is how to elicit statements from children without sacrificing the truth, the rights of those against whom the child is testifying, and the welfare of the child.


11. Abuse Disclosure: What Adults Can Tell., Thomas D. Lyon Dec 2008

11. Abuse Disclosure: What Adults Can Tell., Thomas D. Lyon

Thomas D. Lyon

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 …

9. Authors’ Response To Vieth, Thomas D. Lyon

Thomas D. Lyon

In 2007, Lamb, Orbach, Hershkowitz, Esplin, and Horowitz published in Child Abuse & Neglect a review of empirical research on the National Institute of Child Health and Development (NICHD) Investigative Interview Protocol in which they provided extensive research supporting the conclusion that the NICHD Protocol “comprises a useful and usable set of guidelines that allow trained interviewers to conduct investigative interviews that hew more closely than they otherwise would to universally endorsed professional guidelines” (p. 1212).


19. Young Children’S Competency To Take The Oath: Effects Of Task, Maltreatment, And Age., Thomas D. Lyon, Nathalie Carrick, Jodi A. Quas Dec 2008

19. Young Children’S Competency To Take The Oath: Effects Of Task, Maltreatment, And Age., Thomas D. Lyon, Nathalie Carrick, Jodi A. Quas

Thomas D. Lyon

This study examined maltreated and non-maltreated children’s (N = 183) emerging understanding of ‘‘truth’’ and ‘‘lie,’’ terms about which they are quizzed to qualify as competent to testify. Four- to six-year-old children were asked to accept or reject true and false (T/F) statements, label T/F statements as the ‘‘truth’’ or ‘‘a lie,’’ label T/F statements as ‘‘good’’ or ‘‘bad,’’ and label ‘‘truth’’ and ‘‘lie’’ as ‘‘good’’ or ‘‘bad.’’ The youngest children were at ceiling in accepting/rejecting T/F statements. The labeling tasks revealed improvement with age and children performed similarly across the tasks. Most children were better able to evaluate ‘‘truth’’ …


18. Complex Questions Asked By Defense Lawyers But Not Prosecutors Predicts Convictions In Child Abuse Trials., Angela D. Evans, Kang Lee, Thomas D. Lyon Jul 2008

18. Complex Questions Asked By Defense Lawyers But Not Prosecutors Predicts Convictions In Child Abuse Trials., Angela D. Evans, Kang Lee, Thomas D. Lyon

Thomas D. Lyon

Attorneys’ language has been found to influence the accuracy of a child’s testimony, with defense attorneys asking more complex questions than the prosecution (Zajac & Hayne, J. Exp Psychol Appl 9:187–195, 2003; Zajac et al. Psychiatr Psychol Law, 10:199–209, 2003). These complex questions may be used as a strategy to influence the jury’s perceived accuracy of child witnesses. However, we currently do not know whether the complexity of attorney’s questions predict the trial outcome. The present study assesses whether the complexity of questions is related to the trial outcome in 46 child sexual abuse court transcripts using an automated linguistic …


17. Maltreated Children’S Understanding Of And Emotional Reactions To Dependency Court Involvement., Jodi A. Quas, Allison R. Wallin, Briana Horwitz, Thomas D. Lyon Mar 2008

17. Maltreated Children’S Understanding Of And Emotional Reactions To Dependency Court Involvement., Jodi A. Quas, Allison R. Wallin, Briana Horwitz, Thomas D. Lyon

Thomas D. Lyon

Little is known about the extent to which maltreated children understand what is happening during their participation in court proceedings, despite large numbers of children coming into contact with the legal system as victims of maltreatment. In the present study, maltreated 4- to 15-year-olds were interviewed about their understanding of dependency court on the day of their scheduled court visit. Their feelings about attending their hearings were also assessed, and after their hearing, their understanding of the decisions was examined. Age-related improvements in children’s understanding emerged. Also, children who were more knowledgeable about the legal system were less distressed about …


16. Coaching, Truth Induction, And Young Maltreated Children’S False Allegations And False Denials., Thomas D. Lyon, Lindsay C. Malloy, Jodi A. Quas, Victoria A. Talwar Feb 2008

16. Coaching, Truth Induction, And Young Maltreated Children’S False Allegations And False Denials., Thomas D. Lyon, Lindsay C. Malloy, Jodi A. Quas, Victoria A. Talwar

Thomas D. Lyon

This study examined the effects of coaching (encouragement and rehearsal of false reports) and truth induction (a child-friendly version of the oath or general reassurance about the consequences of disclosure) on 4- to 7-year-old maltreated children’s reports (N 5 198). Children were questioned using free recall, repeated yes – no questions, and highly suggestive suppositional questions. Coaching impaired children’s accuracy. For free-recall and repeated yes – no questions, the oath exhibited some positive effects, but this effect diminished in the face of highly suggestive questions. Reassurance had few positive effects and no ill effects. Neither age nor understanding of the …


8. The Supreme Court, Hearsay, And Crawford: Implications For Child Interviewers., Thomas D. Lyon Dec 2007

8. The Supreme Court, Hearsay, And Crawford: Implications For Child Interviewers., Thomas D. Lyon

Thomas D. Lyon

We are entering the golden age of child interviewing. After years of research emphasizing how children's statements may be corrupted by coercive questioning practices, a number of researchers have shifted their focus toward finding means of increasing the accuracy and completeness of children's reports. Interviewers can now refer to a body of research identifYing good interview practice (Lamb, Hershkowitz, Orbach, & Esplin, 2008).


15. Truth Induction In Young Maltreated Children: The Effects Of Oath-Taking And Reassurance On True And False Disclosures., Thomas D. Lyon, Joyce R. Dorado Dec 2007

15. Truth Induction In Young Maltreated Children: The Effects Of Oath-Taking And Reassurance On True And False Disclosures., Thomas D. Lyon, Joyce R. Dorado

Thomas D. Lyon


Objective: Two studies examined the effects of the oath or reassurance (“truth induction”) on 5- to 7-year-old maltreated children’s true and false reports of a minor transgression.
Methods: In both studies an interviewer elicited a promise to tell the truth, reassured children that they would not get in trouble for disclosing the transgression, or gave no instructions before questioning the child. In Study 1, children were encouraged to play with an attractive toy by a confederate, who then informed them that they might get in trouble for playing. In Study 2, a confederate engaged children in play, but did not …


14. Filial Dependency And Recantation Of Child Sexual Abuse Allegations., Lindsay C. Malloy, Thomas D. Lyon, Jodi A. Quas Apr 2007

14. Filial Dependency And Recantation Of Child Sexual Abuse Allegations., Lindsay C. Malloy, Thomas D. Lyon, Jodi A. Quas

Thomas D. Lyon

Objective: Controversy abounds regarding the process by which child sexual abuse victims disclose their experiences, particularly the extent to which and the reasons why some children, once having disclosed abuse, later recant their allegations. This study examined the prevalence and predictors of recantation among 2- to 17-year-old child sexual abuse victims. Method: Case files (n = 257) were randomly selected from all substantiated cases resulting in a dependency court filing in a large urban county between 1999 and 2000. Recantation (i.e., denial of abuse postdisclosure) was scored across formal and informal interviews. Cases were also coded for characteristics of the …


10. False Denials: Overcoming Methodological Biases In Abuse Disclosure Research., Thomas D. Lyon Jan 2007

10. False Denials: Overcoming Methodological Biases In Abuse Disclosure Research., Thomas D. Lyon

Thomas D. Lyon

When Roland Summit published his paper on child sexual abuse accommodation (Summit, 1983), the notion that sexually abused children disclose abuse only reluctantly and ambivalently was thought "so basic that it contributed nothing new to the literature" (Summit, 1992, p. 155). Summit's paper was neither original research nor a systematic review of research, and he emphasized that his conclusions were largely based on his work as a clinical consultant and "endorsements" from professionals, victims, and their families (Summit, 1983, p. 180).


7. The History Of Children’S Hearsay: From Old Bailey To Post-Davis., Thomas D. Lyon, Raymond Lamagna Dec 2006

7. The History Of Children’S Hearsay: From Old Bailey To Post-Davis., Thomas D. Lyon, Raymond Lamagna

Thomas D. Lyon

In Crawford v. Washington and Davis v. Washington, the United States Supreme Court profoundly changed how hearsay statements are analyzed under the Confrontation Clause. If a hearsay statement is “testimonial,” then the statement cannot be admitted against a criminal defendant unless the defendant had the opportunity to cross-examine the hearsay declarant. Testimonial statements include many, if not most, statements to law enforcement, particularly if elicited through structured interviews and captured on tape. The full reach of the “testimonial” concept, however, has not been determined.

13. From Post-Mortem To Preventive Medicine: Next Steps For Research On Child Witnesses., Thomas D. Lyon, Karen J. Saywitz Mar 2006

13. From Post-Mortem To Preventive Medicine: Next Steps For Research On Child Witnesses., Thomas D. Lyon, Karen J. Saywitz

Thomas D. Lyon

We propose five directions for future child witness research, inspired by recognition of the day-to-day realities of the legal system and the opportunities of psychology to react proactively to challenges child witnesses face. These directions include (1) the refinement of developmentally sensitive questioning aids that increase completeness without increasing suggestibility, (2) the development of approaches to non-disclosure and recantation, including understanding of the reasons underlying non-disclosure and the potential for building rapport and increasing trust, (3) the construction of interventions that meet mental health needs of child-victim witnesses without creating false memories or tainting testimony, (4) a focus on details …


12. Caregiver Support And Child Sexual Abuse: Why Does It Matter?, Lindsay C. Malloy, Thomas D. Lyon Feb 2006

12. Caregiver Support And Child Sexual Abuse: Why Does It Matter?, Lindsay C. Malloy, Thomas D. Lyon

Thomas D. Lyon

Coohey’s paper is a valuable investigation of the substantiation of mothers for failure to protect their children from child sexual abuse (CSA). Drawing on concerns regarding the possible inconsistency of decisions to substantiate, the author sought to determine the factors relied on by CPS investigators in the decision-making process. Multivariate analyses revealed the importance of maternal reactions to abuse, including whether the mother believed the child’s allegations and whether she acted in a protective or supportive manner. We will put Coohey’s findings in the context of other research that has documented the importance of nonoffending caregivers’ reactions to sexual abuse. …

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 …


9. Domestic Violence And Child Protection: Confronting The Dilemmas In Moving From Family Court To Dependency Court., Thomas D. Lyon, Mindy B. Mechanic Dec 2005

9. Domestic Violence And Child Protection: Confronting The Dilemmas In Moving From Family Court To Dependency Court., Thomas D. Lyon, Mindy B. Mechanic

Thomas D. Lyon

The overlap between domestic violence and child maltreatment has received an enormous amount of attention from domestic violence advocates, child advocates, policymakers, and researchers. The goals of empowering victims of domestic violence, usually women, and protecting children from abuse and neglect, usually by men, are theoretically compatible and mutually reinforcing. However, advocacy for battered mothers and protection for maltreated children have developed along different paths, leading to conflict and distrust (Edleson, 1999).

Thomas D. Lyon

THE POLICY FORUM “THE SCIENCE OF CHILD sexual abuse” by J. J. Freyd et al. (22 Apr., p. 501) provides an extremely important call to action to the scientific community.  In 1999, James Mercy, Senior Scientist at the U.S. Centers for Disease Control and Prevention, noted the importance of viewing child sexual abuse with “new eyes” (1).  The implementation of Freyd et al.’s policy recommendations would help us to do this.  For too long, the fact that the topic makes us uneasy has caused too many of us to avert our eyes. But what if child sexual abuse were a …


10. Development Of Temporal-Reconstructive Abilities., William J. Friedman, Thomas D. Lyon Nov 2005

10. Development Of Temporal-Reconstructive Abilities., William J. Friedman, Thomas D. Lyon

Thomas D. Lyon

In a study of the ability to reconstruct the times of past events, 86 children from 4 to 13 years recalled the times of 2 in-class demonstrations that had occurred 3 months earlier and judged the times of hypothetical events. Many of the abilities needed to reconstruct the times of events were present by 6 years, including the capacity to interpret many temporally relevant cues, but there were substantial changes well into middle childhood in the availability of temporally useful episodic information. Children were poor at remembering the events’ proximity or order with respect to a major holiday, but the …

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 …


8. Speaking With Children: Advice From Investigative Interviewers., Thomas D. Lyon Dec 2004

8. Speaking With Children: Advice From Investigative Interviewers., Thomas D. Lyon

Thomas D. Lyon

Imagine that you are treating a child suffering from the effects of neglect. You do not suspect sexual abuse, and do not directly question the child about abuse, but she makes what sounds like anabuse disclosure. Or, you hear from another source (a sibling, for example, or a caretaker) that thechild has made statements hinting that she was abused. What should you do? If you decide to question the child, you may inadvertently suggest information. Even if you are careful to avoid
leading questions, you may later be attacked for contaminating the child=s story, given the inherent polarization …


7. The Supreme Court And Reluctant Witnesses: Crawford V. Washington., Thomas D. Lyon Aug 2004

7. The Supreme Court And Reluctant Witnesses: Crawford V. Washington., Thomas D. Lyon

Thomas D. Lyon

A recent U.S. Supreme Court case is sure to have a major impact on the prosecution of family violence cases in which the victim fails to testify at trial.  A number of states have special hearsay exceptions for statements from victims of spouse abuse and child abuse.  Those exceptions often allow the statements into evidence even when the victim does not testify (usually with additional requirements, such as corroborative evidence or a finding that the statement has "indicia of reliability").  The U.S. Supreme Court has recently held that if the victim does not testify, "testimonial" hearsay is inadmissible unless the …
