Mock Jurors' Perceptions of Child Sexual Abuse Cases: Investigating the Role of Delayed Disclosure and Relationship to the Perpetrator.

Child sexual abuse (CSA) claims brought forward weeks, months, or years after the alleged events are commonplace, yet the trial-level ramifications of delayed disclosure remain unclear. In the present study, we investigated the influence of length of delayed disclosure (1 day, 1 month, 10 months) as a function of the victim-perpetrator relationship (next-door neighbor, stepfather) on mock jurors' perceptions of a CSA case. Jury-eligible participants (N = 328) read a mock trial summary describing an alleged incident of CSA between an adult male defendant and a seven-year-old female victim. Participants then rendered various case judgments. When length of delay was 10 months versus 1 day, mock jurors rendered fewer guilty verdicts and lower ratings of victim trustworthiness, believability, memory strength, and memory accuracy. Effects of length of delay varied as a function of the victim-perpetrator relationship, but only when the perpetrator was the victim's next-door neighbor versus stepfather. When the perpetrator was the victim's next-door neighbor, participants rated the likelihood of abuse as higher and the victim's memory as stronger with shorter versus longer lengths of delay. Delay did not vary as a function of the victim-perpetrator relationship when the perpetrator was the victim's stepfather. Findings have implications for trial-level safeguards (e.g., expert testimony) in CSA cases involving delayed disclosure.

Analyzing the scientific foundation of Child Sexual Abuse Accommodation Syndrome: A reply to Lyon et al.

The issue before the New Jersey Supreme Court in the Frye hearing New Jersey v. J.L.G. (2018) was whether the scientific community agreed that Summit's (1983) Child Sexual Abuse Accommodation Syndrome rested on a firm scientific foundation. Lyon et al. (this issue) critique our approach to describing child sexual abuse disclosure, which involved extrapolating rates from children who came to the attention of authorities. Lyon et al. claim that our conclusions are marred by sampling biases resulting from what they term the ground truth problem, suspicion bias and substantiation bias. The points Lyon et al. claim we "fell victim to" were the very points we acknowledge are inherent difficulties in estimating the extent to which children will come forward to tell others about sexual maltreatment. Lyon et al. offer an alternative solution to the inherent difficulties in studying a difficult-to-identify population, relying in large part on 21 papers published mostly in the 1960s and 1970s. We argue that the method they propose has more flaws than the one it is intended to replace. Points of agreement and disagreement, along with suggestions for future research, are discussed. Moving forward, we argue that studies are needed that embrace both validity and generalizability in order to foster data-driven theories rather than invoking the intuitive suppositions of Summit's (1983) syndromal evidence.

A retrospective approach to examining child abuse disclosure.

BACKGROUND: Often times, a child's disclosure is the only forensic evidence available in child abuse cases. Therefore, understanding disclosure patterns of suspected child abuse victims plays a critical role in the forensic investigations of both child physical abuse (CPA) and child sexual abuse (CSA) cases. OBJECTIVE: To explore adults' retrospective reports about childhood disclosure of CPA and CSA. PARTICIPANTS AND SETTING: College students (N = 907) were screened for reported histories of CSA (n = 94) or CPA (n = 109). METHODS: Through an online survey, participants provided anonymous information regarding CSA and CPA experiences along with information about any disclosure events or opportunities that they have encountered since the abuse. RESULTS: Among the adults reporting CSA histories, 50 % indicated disclosing the abuse during childhood; 80 % indicated any lifetime disclosure. Among the adults indicating CPA histories, 32 % reportedly disclosed the abuse to someone during childhood with 52 % reporting any lifetime disclosure. For both groups, length of delay until disclosure was bimodal with many individuals reporting immediately and many waiting considerable time. Among adults reporting CSA, a minority (16 %) indicated the abuse came to the attention of authorities, with even fewer CPA cases (8%) reporting authorities were aware of their abuse. Denial and recantation in a formal setting was infrequent regardless of abuse type reported. CONCLUSIONS: Given that participants experiencing CSA and CPA both reported low levels of denial and recantation, forensic investigators and practitioners may benefit from considering consistent interviewing approaches and protocols, regardless of the type of abuse suspected.

Common Beliefs About Child Sexual Abuse and Disclosure: A College Sample.

Adults' common beliefs about child sexual abuse and disclosure were explored. Participants (N = 670) were questioned about key areas of child sexual abuse that could affect decision-making processes of jurors evaluating child sexual abuse cases. These areas included victim and perpetrator characteristics, medical and behavioral indicators of child sexual abuse, memories for the event, and disclosure of the event. The scientific literature pertaining to these same areas are reviewed. While individual beliefs were consistent with some areas of the scientific literature (e.g., victim and perpetrator characteristics), they strongly contrasted the literature in other important areas (e.g., memories for the event, indicators of child sexual abuse, and the likelihood of denial and recantation). Implications, including the option of providing expert testimony to reduce discrepancies, are discussed.

Tell Me Everything You Discussed: Children's Memory for Dyadic Conversations after a 1-Week or a 3-Week Delay.

In child abuse investigations, children are often asked to recount previous conversations related to the allegations (i.e., "conversational testimony"). To explore children's ability to provide conversational testimony, we staged a semi-structured novel dyadic conversation between an adult researcher and 8-year-old children (n = 90). Children's gist recall and recognition memory for their own statements, their conversational partner's statements, and question-answer pairs were tested after either a 1-week or a 3-week delay. The results revealed that children recounted a minority of the conversation, although children recalled more after a short delay (7%) than after a long delay (4%). A majority of children's free recall statements were accurate (68%); however, approximately one-third of their free recall statements were incorrect. Children almost exclusively recounted their own statements, and rarely recalled any of the adult's statements or the question-answer pairs during free recall. Reports of the adult's statements and question-answer pairs increased with cued recall questioning, but remained minimal. During recognition testing, children were able to distinguish between true and false recognition items for their own statements and the adult's statements, but performed at chance level on recognition items concerning question-answer pairs. Forensic implications of the results are discussed.

Young children's ability to use two-dimensional and three-dimensional symbols to show placements of body touches and hidden objects.

In two experiments, we investigated 3- to 5-year-old children's ability to use dolls and human figure drawings as symbols to map body touches. In Experiment 1, stickers were placed on different locations of children's bodies, and the children were asked to indicate the locations of the stickers using three different symbols: a doll, a human figure drawing, and the adult researcher. Performance on the tasks increased with age, but many 5-year-olds did not attain perfect performance. Surprisingly, younger children made more errors on the two-dimensional (2D) human figure drawing task compared with the three-dimensional (3D) doll and adult tasks. In Experiment 2, we compared children's ability to use 3D and 2D symbols to indicate body touch as well as to guide their search for a hidden object. We replicated the findings of Experiment 1 for the body touch task; for younger children, 3D symbols were easier to use than 2D symbols. However, the reverse pattern was found for the object locations task, with children showing superior performance using 2D drawings over 3D models. Although children showed developmental improvements in using dolls and drawings to show where they were touched, less than two thirds of the 5-year-olds performed perfectly on the touch tasks. Both developmental and forensic implications of these results are discussed.

Misconceptions about childhood sexual abuse and child witnesses: Implications for psychological experts in the courtroom.

Recent changes to the law in New Zealand have led to a marked increase in experts being called to give evidence in cases of alleged child sexual abuse. Here we outline some of the common misconceptions that are held by expert witnesses in these cases and we review research on patterns of abuse disclosure and retraction, symptoms of abuse, external influences on children's reports, and experts' ability to distinguish true from false reports. We also consider what experts can say about memory that has relevance for these cases. We conclude that many long-held notions of child sexual abuse and children's testimony that make their way into our courtrooms are not supported by empirical research, raising questions about who is-and who is not-qualified to act as an expert witness.

Peer influence on event reports among adolescents and young adults.

When two or more people witness an event together, the event report from one person can influence others' reports. In the current study we examined the role of age and motivational factors on peer influence regarding event reports in adolescents and young adults. Participants (N=249) watched a short video of a robbery then answered questions with no co-witness information or with information believed to be from a co-witness. Public and private response conditions were included to explore motivations for peer influence. Co-witness information influenced participants' responses, although the effect was equally strong in the private and the public co-witness conditions. Peer influence on event reports was steady across a large age range (11- to 25-year-olds).

Expert testimony regarding child witnesses: does it sensitize jurors to forensic interview quality?

Does expert testimony on forensic interviews with children help adults distinguish between poorly conducted and well-conducted interviews? This study evaluates the effects of social framework expert testimony regarding child witnesses in a case involving allegations of child sexual abuse. A 2 (Expert Testimony: present or absent) × 3 (Child Forensic Interview Quality: poor, typical, or good) × 2 (Child's Age: 4- or 10-year-old) factorial design was used to examine whether expert testimony is prejudicial or beneficial to jurors (N = 463). The results revealed that, without expert testimony, mock jurors did not consider the forensic interview quality when reaching a verdict. However, with expert testimony, mock jurors were more likely to render guilty verdicts if the interview quality was good versus poor. Further expert testimony increased mock jurors' knowledge about child witnesses. These findings suggest that expert testimony related to the impact of interview techniques on the reliability of children's reports may assist fact-finders in evaluating child abuse cases.

Post-event information affects children's autobiographical memory after one year.

In two experiments, we examined whether post-event information (PEI) about true and false events persisted in children's reports after approximately 1 year. In Experiment 1, 4- to 6-year-olds were given PEI and then were given memory tests 2 weeks and 15 months later. Although PEI appeared in free recall at the initial testing, it decreased substantially by the long-term test. In contrast, on recognition tasks the children showed facilitation and misinformation effects at initial and follow-up tests. Experiment 2 replicated lasting misinformation and facilitation effects in recognition memory among 4- to 9-year-olds who were tested after 1-week and 10-month delays. We conclude that true and false reminders about an experienced event continue to affect children's memory approximately 1 year later.

Multilevel modelling: Beyond the basic applications.

Over the last 30 years statistical algorithms have been developed to analyse datasets that have a hierarchical/multilevel structure. Particularly within developmental and educational psychology these techniques have become common where the sample has an obvious hierarchical structure, like pupils nested within a classroom. We describe two areas beyond the basic applications of multilevel modelling that are important to psychology: modelling the covariance structure in longitudinal designs and using generalized linear multilevel modelling as an alternative to methods from signal detection theory (SDT). Detailed code for all analyses is described using packages for the freeware R.

Changing the criterion for memory conformity in free recall and recognition.

People's responses during memory studies are affected by what other people say. This memory conformity effect has been shown in both free recall and recognition. Here we examine whether accurate, inaccurate, and suggested answers are affected similarly when the response criterion is varied. In the first study, participants saw four pictures of detailed scenes and then discussed the content of these scenes with another participant who saw the same scenes, but with a couple of details changed. Participants were either told to recall everything they could and not to worry about making mistakes (lenient), or only to recall items if they were sure that they were accurate (strict). The strict instructions reduced the amount of inaccurate information reported that the other person suggested, but also reduced the number of accurate details recalled. In the second study, participants were shown a large set of faces and then their memory recognition was tested with a confederate on these and fillers. Here also, the criterion manipulation shifted both accurate and inaccurate responses, and those suggested by the confederate. The results are largely consistent with a shift in response criterion affecting accurate, inaccurate, and suggested information. In addition we varied the level of secrecy in the participants' responses. The effects of secrecy were complex and depended on the level of response criterion. Implications for interviewing eyewitnesses and line-ups are discussed.

Review of the contemporary literature on how children report sexual abuse to others: findings, methodological issues, and implications for forensic interviewers.

Methods used during forensic interviews with children are driven by beliefs about how children recall and report child sexual abuse (CSA) to others. Summit (1983) proposed a theory (Child Sexual Abuse Accommodation Syndrome) contending that, due to the specific traumatic characteristics of CSA, children will often delay disclosing abuse or altogether fail to disclose during childhood, deny abuse when asked, and often recant abuse allegations. His theory has had a tremendous impact on the field of CSA forensic evaluations, despite its dearth of empirical support. In this paper, we review and critique the contemporary literature from two main sources: retrospective accounts from adults reporting CSA experiences and studies of children undergoing forensic evaluation for CSA. We conclude that data support the notion that children often delay abuse disclosure, but that among valid abuse cases undergoing forensic evaluation, denial and recantation are not common. Methodological issues and implications for forensic interviewers are discussed.

Children's attention to beliefs in interactive persuasion tasks.

Whether and when children can apply their developing understanding of belief to persuasion was examined using interactive puppet tasks. Children selected 1 of 2 arguments to persuade a puppet to do something (e.g., pet a dog) after hearing the puppet's belief (e.g., "I think puppies bite"). Across 2 studies, 132 children (ages 3-7 years) engaged in these persuasion tasks and in false-belief reasoning tasks, presented in puppet and story formats. Belief-relevant argument selection increased with age, as did appropriate reasoning about false beliefs, and occurred more in puppet than story tasks. Results suggest that improvements in belief reasoning in early childhood may be reflected in social interactions such as persuasion.

Autobiographical memory and suggestibility in children with autism spectrum disorder.

Two paradigms were developed to examine autobiographical memory (ABM) and suggestibility in children with autism spectrum disorder (ASD). Children with ASD (N = 30) and typically developing chronological age-matched children (N = 38) ranging in age from 5 to 10 years were administered an ABM questionnaire. Children were asked about details of current and past personally experienced events. Children also participated in a staged event, and later were provided with true and false reminders about that event. Later, children again were interviewed about the staged event. The results from both paradigms revealed that children with ASD showed poorer ABM compared to controls. Generally, their ABM was marked by errors of omission rather than by errors of commission, and memory was particularly poor for early-life events. In addition, they were as suggestible as the typically developing children. The results are discussed in terms of applied and theoretical implications.

Examining the efficacy of truth/lie discussions in predicting and increasing the veracity of children's reports.

This study investigated whether children's ability to reason about truths and lies influenced their truth-telling behavior. Four-six-year-old children (n=118) played a game that was intended to motivate children to use deception to hide a minor transgression. Next, an interviewer gave children one of four preliminary discussions. Children received a typical forensic truth/lie discussion (TLD), a developmentally appropriate and more elaborate TLD, or one of two discussions that controlled for the time spent conversing with children. Children were interviewed about the event. The results revealed that children's performance on the truth/lie questions did not predict their truth-telling behavior. Regardless of their performance on truth/lie questions, children who received TLD's gave more honest reports than children who did not receive TLD's. These results suggest that discussing truths and lies with children may promote truth-telling behavior. However, the results cast doubt on the validity of using children's performance on truth/lie questions as a measure of competency.
