The role of repeated interviewing in children's responses to cross-examination-style questioning

The negative effect of cross-examination-style questioning on children's accuracy is likely to be due to the complex and credibility-challenging questions that characterize the interview. Given that cross-examination occurs after at least one prior interview, however, it is equally possible that repeated interviewing per se impairs children's accuracy, and that the questions asked have little bearing on children's responses. To examine this issue, 5- and 6-year-old children (n= 82) and 9- and 10-year-old children (n= 103) took part in a surprise event and were then interviewed using an analogue of direct examination. Either 1 week or 6 months later, half of the children were re-interviewed with an analogue of cross-examination designed to challenge their direct examination responses. Remaining children were re-interviewed with the same questions that were asked during direct examination. Children's accuracy decreased following their second interview, irrespective of age or delay; however, delay particularly impacted younger children's second interview performance. Children's accuracy was most impaired following a cross-examination-style interview. Overall, cross-examination-style questioning appears to be particularly detrimental to obtaining accurate event reports from children.

Interviewing children versus tossing coins: accurately assessing the diagnosticity of children's disclosures of abuse

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 distinction between true and false disclosures. We review interviewing methods that increase the probative value of disclosures, including interview instructions, narrative practice, noncontingent reinforcement, and questions about perpetrator/caregiver statements and children's reactions to the alleged abuse.

Social processes affecting the mnemonic consequences of rumors on children's memory

This research examined whether the impact of overheard rumors on children's memory for their experiences varies as a function of social processes. The results of two experiments revealed that the very same errant rumor had different consequences for children's recollections depending on the degree and type of social interactions they had with peers after exposure to the rumor. In both experiments, 3- to 5-year-olds overheard a false rumor about a recently experienced event and then were interviewed about the event 1 week later. In Experiment 1, children were more likely to report experiencing rumored-but-nonoccurring information if they were allowed to interact naturally with peers following exposure to the rumor than if they were prevented from peer exchange. In Experiment 2, exposure to the rumor induced greater memory contamination if it was planted among familiar peers than if it was encountered among strangers.

False rumors and true belief: memory processes underlying children's errant reports of rumored events

Previous research has shown that overhearing an errant rumor--either from an adult or from peers--about an earlier experience can lead children to make detailed false reports. This study investigates the extent to which such accounts are driven by changes in children's memory representations or merely social demands that encourage the reporting of rumored information. This was accomplished by (a) using a warning manipulation that eliminated social pressures to report an earlier heard rumor and (b) examining the qualitative characteristics of children's false narratives of a rumored-but-nonexperienced event. Findings indicated that overheard rumors can induce sensory and contextual characteristics in memory that can lead children to develop genuine false beliefs in seeing rumored-but-nonexperienced occurrences. Such constructive tendencies were especially likely among 3- and 4-year-olds (relative to 5- and 6-year-olds) and when rumors were picked up from peers during natural social interactions (relative to when they were planted by an adult).

Allegations of sexual abuse of a child: what to do when a single forensic interview isn't enough

This article describes the state of knowledge about extended assessments/forensic evaluations in situations of possible sexual abuse. It provides a critical review of the modest body of relevant research, describes two models for extended assessments, and presents descriptive survey findings of 62 professionals conducting extended assessments, most of whom conduct extended assessments intermittently as part of their other work on sexual abuse cases. Agencies should consider conducting extended assessments with young or traumatized children whose sexual abuse allegations are not resolved with a single interview as well as in complex child sexual abuse cases.

The development of stereotyping and exclusion

This article reviews the developmental science literature on stereotyping and exclusion, with a focus on gender, race, and ethnicity. Stereotyping of others, which is defined as the attribution of traits to individuals based on group membership, is often used to justify exclusion of others in social group contexts. This review includes a focus on the links between these two constructs. Research on stereotyping and exclusion has drawn on several theoretical traditions, including social domain theory, social identity developmental theory, and subjective group dynamics theory, which are also discussed in the context of the research findings. Key findings on stereotyping include categorization and classification in relationship with decreased in-group bias, and the role of stereotypes in encoding information. Findings on exclusion include the use of available information to make judgments, preferences for in-group members who are normative and out-group members who are deviant, the increased importance, with age, of group functioning in exclusion decisions, and decreased negative evaluation of in-group members who partake in exclusionary behaviors. Though little research has explicitly studied the links between stereotyping and exclusion from groups, this review describes the current literature in both areas and suggests future directions for research.

Dealing with conflicting information: young children's reliance on what they see versus what they are told

Children often learn about the world through direct observation. However, much of children's knowledge is acquired through the testimony of others. This research investigates how preschoolers weigh these two sources of information when they are in conflict. Children watched as an adult hid a toy in one location. Then the adult told children that the toy was in a different location (i.e. false testimony). When retrieving the toy, 4- and 5-year-olds relied on what they had seen and disregarded the adult's false testimony. However, most 3-year-olds deferred to the false testimony, despite what they had directly observed. Importantly, with a positive searching experience based on what they saw, or with a single prior experience with an adult as unreliable, 3-year-olds subsequently relied on their first-hand observation and disregarded the adult's false testimony. Thus, young children may initially be credulous toward others' false testimony that contradicts their direct observation, but skepticism can develop quickly through experience.

Do human figure diagrams help alleged victims of sexual abuse provide elaborate and clear accounts of physical contact with alleged perpetrators?

The present study examined whether the use of human figure diagrams within a well-structured interview was associated with more elaborate and clearer accounts about physical contact that had occurred in the course of an alleged abuse. The sample included investigative interviews of 88 children ranging from 4 to 13 years of age. Children were interviewed using the NICHD Investigative Interview Protocol, and were then asked a series of questions in association with unclothed gender-neutral outline diagrams of a human body. A new coding scheme was developed to examine the types and clarity of touch-related information. Use of the HFDs was associated with reports of new touches not mentioned before and elaborations regarding the body parts reportedly touched. The HFDs especially helped clarify reports by the oldest rather than the youngest children. The clarity of children's accounts of touch was also greater when details were sought using recall prompts.

Effects of stereotypes and suggestion on memory

In this study, the interactive effect of stereotype and suggestion on accuracy of memory was examined by presenting 645 participants (native Israelis and immigrants from the former Soviet Union and Ethiopia) with three versions of a story about a worker who is waiting in a manager's office for a meeting. All versions were identical except for the worker's name, which implied a Russian or an Ethiopian immigrant or a person of no ethnic origin. Each participant was presented with one version of the story. After an hour delay, the participants' memories were tested via two questionnaires that differed in terms of level of suggestion. Data analyses show that (a) when a suggestion matched the participant's stereotypical perception, the suggestion was incorporated into memory but (b) when the suggestion contradicted the stereotype, it did not influence memory. The conclusion was that recall is influenced by stereotypes but can be enhanced by compatible suggestions.

Children's eyewitness memory: a comparison of two interviewing strategies as realized by forensic professionals

A critical issue for developmental psychology is how to obtain accurate and complete eyewitness memory reports from preschoolers without offering suggestions that might result in false allegations. We examined effects of two interviewing strategies (police/verbal interviews and clinician/prop-assisted interviews) on young children's reports about a medical examination. A total of 58 4-year-olds participated in the study, which conformed to a 2 (Interview Type)x2 (Number of Interviews) factorial design. Analyses revealed that interviewers spent less time off topic and asked more free recall questions in the police/verbal interviews than in the clinician/prop-assisted interviews. Compared with police/verbal interviews, clinician/prop-assisted interviews resulted in significantly more correct rejections and commission errors in children's memory reports. However, on a final free recall test, error rates were comparable across conditions. Higher child verbal intelligence predicted memory accuracy in police/verbal interviews, and greater parental attachment anxiety predicted children being asked a higher number of misleading questions. The study provides new insights into interview techniques that promote preschoolers' accurate eyewitness reports.

Choosing your informant: weighing familiarity and recent accuracy

In two experiments, children aged 3, 4 and 5 years (N = 61) were given conflicting information about the names and functions of novel objects by two informants, one a familiar teacher, the other an unfamiliar teacher. On pre-test trials, all three age groups invested more trust in the familiar teacher. They preferred to ask for information and to endorse the information that she supplied. In a subsequent phase, children watched as the two teachers differed in the accuracy with which they named a set of familiar objects. Half the children saw the familiar teacher name the objects accurately and the unfamiliar teacher name them inaccurately. The remaining half saw the reverse arrangement. In post-test trials, the selective trust initially displayed by 3-year-olds was minimally affected by this intervening experience of differential accuracy. By contrast, the selective trust of 4- and 5-year-olds was affected. If the familiar teacher had been the more accurate, selective trust in her was intensified. If, on the other hand, the familiar teacher had been the less accurate, it was undermined, particularly among 5-year-olds. Thus, by 4 years of age, children trust familiar informants but moderate that trust depending on the informants' recent history of accuracy or inaccuracy.

Adults usually believe young children: the influence of eliciting questions and suggestibility presentations on perceptions of children's disclosures

Do people realize the danger of asking misinformed children yes-no questions? Study 1 confirmed that disclosures children made during free recall in an earlier suggestibility study were more accurate than disclosures following "yes" responses to yes-no questions, which in turn were more accurate than disclosures following "no" responses. In Studies 2 and 3, college students watched interviews of children and judged the veracity of these three disclosure patterns. Participants generally believed false reports representing the first two patterns, although watching expert testimony that included a videotaped example of a false report reduced trust in prompted disclosures. Results document the need to inform forensic decision-makers about the circumstances associated with erroneous responses to yes-no questions.

Expert judgment in cases of alleged child sexual abuse: clinicians' sensitivity to suggestive influences, pre-existing beliefs and base rate estimates

Clinicians' expertise in child sexual abuse (CSA) cases was explored by giving a questionnaire covering clinical experience, self-evaluated expertise, beliefs and attitudes about CSA and a trial material concerning CSA to 320 child mental health professionals. In the material the suggestiveness of the interview with the child was varied and one condition did not contain any interview transcript. Participants were sensitive to the presence of leading questions but not to the presence of other suggestive techniques and not to the possibility that suggestive techniques could have been used when no interview transcripts were included. Experience only affected sensitivity to leading questions. Strong attitudes and beliefs lessened the sensitivity to leading questions and made participants more prone to wanting the case to be prosecuted when other suggestive influences than leading questions were present. Practical implications of the results will be discussed.

The effectiveness of opposing expert witnesses for educating jurors about unreliable expert evidence

We tested whether an opposing expert is an effective method of educating jurors about scientific validity by manipulating the methodological quality of defense expert testimony and the type of opposing prosecution expert testimony (none, standard, addresses the other expert's methodology) within the context of a written trial transcript. The presence of opposing expert testimony caused jurors to be skeptical of all expert testimony rather than sensitizing them to flaws in the other expert's testimony. Jurors rendered more guilty verdicts when they heard opposing expert testimony than when opposing expert testimony was absent, regardless of whether the opposing testimony addressed the methodology of the original expert or the validity of the original expert's testimony. Thus, contrary to the assumptions in the Supreme Court's decision in Daubert, opposing expert testimony may not be an effective safeguard against junk science in the courtroom.

Perceptions and predictors of children's credibility of a unique event and an instance of a repeated event

Perceptions of children's credibility were studied in two experiments wherein participants watched a videotape of a 4- to 5- or a 6- to 7-year old child report details of a play session that had been experienced once (single-event) or was the last in a series of four similar play sessions (repeat-event). The child's report was classified as high or low accurate. In Experiments 1 and 2, reports of repeat-event children were judged to be less believable on several measures. In Experiment 1, younger children were viewed as less credible than older children. In both experiments, neither undergraduates nor community members correctly discriminated between high- and low-accurate reports. Content analysis in Study 3 revealed the relationship between age and event frequency and children's credibility ratings was mediated by the internal consistency of children's reports. Recent research on children's reports of instances of repeated events has identified several challenges facing children who report repeated abuse. These data bring to light another potential difficulty for these children.

Event plausibility does not determine children's false memories

In this paper we ask how the plausibility of an event affects the likelihood that children will develop a false memory for it. Over three interviews 6-year-olds and 10-year-olds were shown two true photos and two false photos-a plausible and less plausible event-and reported what they could remember about those events. Children also rated their confidence that the events happened, and how much they could remember about the events. By the final interview, within each age group, there were no differences in children's confidence ratings for the two false events. In addition, within each age group, the rate of false memories was the same for each event; across age groups, younger children developed more false memories than older children.

Mixing memories: the effects of rumors that conflict with children's experiences

This study examined age differences in children's vulnerability to be misled by two types of false overheard rumors, namely a rumor that suggested a reasonable explanation for an earlier unresolved experience and a rumor that suggested an explanation that conflicted with information already in memory. Results indicated that all of the children were highly susceptible to wrongly report the rumor as an actual experience when it merely filled a gap in memory. However, the 5- and 6-year-olds were better able than the 3- and 4-year-olds to resist the rumor when it suggested a conflicting explanation for a past event. Developmental changes in children's understanding of conflicting mental representations were linked to their ability to resist being misled by the conflicting rumor.

Unwarranted Assumptions about Children's Testimonial Accuracy

We examine eight unwarranted assumptions made by expert witnesses, forensic interviewers, and legal scholars about the reliability of children's eyewitness reports. The first four assumptions modify some central beliefs about the nature of suggestive interviews, age-related differences in resistance to suggestion, and thresholds necessary to produce tainted reports. The fifth unwarranted assumption involves the influence of both individual and interviewer factors in determining children's suggestibility. The sixth unwarranted assumption concerns the claim that suggested reports are detectable. The seventh unwarranted assumption concerns new findings about how children deny, disclose, and/or recant their abuse. Finally, we examine unwarranted statements about the value of science to the forensic arena. It is important not only for researchers but also expert witnesses and court-appointed psychologists to be aware of these unwarranted assumptions.

Improving credibility assessment in child sexual abuse allegations: the role of the NICHD investigative interview protocol

OBJECTIVES

The study was designed to explore whether the credibility of children's statements regarding their alleged experiences of child sexual abuse could be assessed in a more valid and reliable way when investigative interviews were conducted using the NICHD protocol rather than in an unstructured manner.

METHODS

Forty-two experienced Israeli youth investigators each assessed the credibility of allegations of sexual abuse made by alleged victims of sexual abuse when interviewed either with or without the protocol. Half of the alleged incidents were judged likely to have happened ("plausible") on the basis of independent evidence, while half were deemed unlikely to have happened ("implausible").

RESULTS

More non-protocol than protocol interviews were rated as "No judgment possible" rather than either credible or incredible. Allegations made in protocol interviews were more accurately rated as credible or incredible when they were either plausible or implausible, respectively, than those made in non-protocol statements. Levels of inter-rater reliability were also higher when protocol interviews were rated. The differences were significant only for plausible cases, however.

CONCLUSIONS

The use of the NICHD protocol facilitated the assessment of credibility by child investigators although incredible allegations (those describing incidents that were unlikely to have happened) remained difficult to detect, even when the protocol was used.

False Memories

Abstract. In recent years, there has been an explosion of research on false memories: The subjective experience of remembering something if that something did apparently not happen in reality. We review a range of findings concerning this phenomenon: False memories of details and of whole events by adults and children, as well as false memories of words in laboratory experiments (in the DRM paradigm). We also briefly discuss the converse phenomenon: Evidence of forgetting or repression of significant events, and evidence of recovered memories. Knowledge of both phenomena is needed for judging whether “new” memories are false, recovered, or whether both options are possible. More general as well as specific theories explaining false memories are discussed, and we close with implications for practice.
