The Gestural Misinformation Effect in Child Interviews in Switzerland

Gestures embody concepts in the form of universal representations. Researchers have highlighted that social communication often embodies nonverbal behavior. A forensic interviewer’s nonverbal behavior, such as gesturing during an interview, could communicate misleading information and may cause inaccuracies in the interviewees’ testimonies. The current study was conducted in Switzerland and included 108 child participants, in three age groups (a younger sample aged 6–9 years, n = 32) (a middle sample aged 10–11 years, n = 40) and an older sample aged 12–13 years, n = 36). Participants viewed a video and completed an interview about the video, individually, immediately after. During the questioning, the interviewer deliberately misled the interviewees with nonverbal gestures. The results showed that 95 children were misled by at least one gesture and that gestures led to a significant decrease in accuracy. Children also incorporated misleading gestures and reported false information; adding to existing evidence that misinformation can also be communicated through nonverbal gestures. Our findings demonstrate the negative influence of misleading gestures in child eyewitness interviews and provide more evidence for the robustness of the gestural misinformation effect, reported in previous research.

Parents' attachment orientation, interviewers' support, and children's memory for a mildly distressing event

Parents' attachment orientations predict children's memory about distressing life events, such that parents who are less secure in close relationships tend to have children who are less accurate in their memory reports. This study examined whether socially supportive interviewing would reduce differences in children's memory performance associated with parents' attachment. Children (3 to 5 years, N = 63) and their primary caretakers took part in the Preschool Attachment Classification System (PACS), a moderately distressing event for children of preschool age that is based on the Strange Situation Procedure. Children's memory for the event was then tested shortly thereafter by either a supportive or a non-supportive interviewer. In the non-supportive condition, children whose parents scored higher on attachment avoidance provided lower proportions of correct free recall. However, the association was not significant for children in the supportive condition. In addition, higher parental attachment anxiety predicted lower proportions of correct free recall for children of highly avoidant parents, but not for children of parents lower in attachment avoidance. For direct questions, age differences in proportion correct and proportion incorrect favoured older children. Findings provide insight into interviewing techniques at time of memory retrieval that benefit children of insecure parents.

The dynamics of two-session interviews with suspected victims of abuse who are reluctant to make allegations

Supportive forensic interviews conducted in accordance with the National Institute of Child Health and Human Development Revised Protocol (RP) help many alleged victims describe abusive experiences. When children remain reluctant to make allegations, the RP guides interviewers to (a) focus on rapport building and nonsuggestive support in a first interview, and (b) plan a second interview to allow continued rapport building before exploring for possible abuse. We explored the dynamics of such two-session RP interviews. Of 204 children who remained reluctant in an initial interview, we focused on 104 who made allegations when re-interviewed a few days later. A structural equation model revealed that interviewer support during the first session predicted children's cooperation during the rapport-building phase of the second session, which, in turn, predicted more spontaneous allegations, which were associated with the interviewers' enhanced use of open-ended questions. Together, these factors mediated the effects of support on children's free recall of forensically important information. This highlighted the importance of emphasizing rapport with reluctant children, confirming that some children may need more time to build rapport even with supportive interviewers.

Implicit Encouragement: Enhancing Youth Productivity when Recounting a Stressful Experience

In recent years, increasing efforts have been focused on testing strategies of improving victimized children's narrative productivity, given that, for many youth, finding out what has happened to them is crucial to intervening and promoting their well-being. Implicit encouragement strategies, such as back channeling by conversational partners, have shown some preliminary promise, but their precise effects on productivity and accuracy have not been adequately examined. In this study, 98 youth, ages 8-14, completed a laboratory-based stressful activity, and a week later, a surprise memory test regarding what happened in the lab activity. Interviewers varied their use of implicit encouragement. Open-ended recall questions asked youth about both factual details and detail about their feelings and thoughts during the laboratory activity. Implicit encouragement increased the amount of both types of details and had no effect on errors. In fact, few youth provided any incorrect information in their recall reports. Neither age nor stress was related to youth's productivity or accuracy, directly or in conjunction with implicit encouragement. Results highlight the value of interviewers using encouraging behaviors when questioning children and adolescents to elicit a range of information about prior stressful experiences.

Canine-Assisted Interviews Bolster Informativeness for Negative Autobiographical Memories

Humans and animals share a unique bond. Professionals are capitalizing on the human–animal bond by incorporating animals into therapy, forensic interviews, and the courtroom. However, the mnemonic consequence for including dogs in forensic interviews has not been empirically evaluated. In the current study, we examined whether the use of dogs increases the quantity of verbal reports for emotional events. Undergraduate participants were randomly assigned to dog or no dog conditions. Participants were interviewed about positive experienced events and negative experienced events. All interviews were audio recorded, transcribed verbatim, and analyzed for quantity of new information. Participants shared more new information in negative event reports with a dog present than with no dog present. There were no significant differences in the quantity of information disclosed for positive event memories between dog conditions. Canine-assisted interviews may provide comfort to people, resulting in more elaborative autobiographical reports about negative stressful events.

Effects of Delay, Question Type, and Socioemotional Support on Episodic Memory Retrieval by Children with Autism Spectrum Disorder

Twenty-seven autistic children and 32 typically developing (TD) peers were questioned about an experienced event after a two-week delay and again after a two-month delay, using the Revised National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol. Recall prompts elicited more detailed and more accurate responses from children than recognition prompts. Autistic children recalled fewer correct narrative details than TD peers when questioned using open invitations, cued invitations, and directive questions. Nonetheless, they were as accurate as TD peers when responding to all types of prompts. The informativeness and accuracy of children's reports remained unchanged over time. Social support was beneficial when children were interviewed for the first time but not after a longer delay.

Using implicit encouragement to increase narrative productivity in children: Preliminary evidence and legal implications

Statements made by children in a range of legal settings can irrevocably impact their family structure, relationships, and living environment. Because these statements can fundamentally alter children's futures, efforts have been made to identify methods to enhance children's reports by increasing comprehensiveness, completeness, and accuracy. Interviewer support has broadly been considered a method of interest, but variations in what constitutes "support" have highlighted the need for greater specificity in documenting how different facets of supportive behaviors relate to children's reporting tendencies. In this review, we describe work focused on the effects of interviewer support, on children's memory completeness and accuracy. We then describe to a subset of interviewer behaviors that encourage elaboration in dyadic interactions: back-channeling and vocatives. We present preliminary evidence suggesting that these utterances, referred to as implicit encouragement, can increase the amount of detail provided without compromising accuracy. Implications for custody evaluations are discussed.

Effects of Interviewer Support on Children's Memory and Suggestibility: Systematic Review and Meta-Analyses of Experimental Research

The accuracy of children's reports of abuse has been hotly debated in the press, academia, and the courtroom. Yet, children's accuracy depends, in part, on the context in which children are interviewed. Guidelines often recommend creating a supportive psychosocial context to promote open, honest responding; however, there is also concern that support promotes social desirability and acquiescence to suggestion, leading children to report more of what they perceive adults want to hear than the truth. The question remains as to whether there is a sufficient body of scientific research to determine whether interviewer supportiveness improves interview outcomes while minimizing children's stress or whether it increases suggestibility and impairs accuracy. Using a systematic search strategy and meta-analyses, this study identifies and reviews findings from experimental studies of the effects of interviewer supportiveness on the accuracy of children's reports. Although the number of studies in the evidence base is small ( n = 15), the studies are of relatively good quality. Results suggest noncontingent interviewer support bolsters children's accuracy. Children are more resistant and less acquiescent to suggestive questions when interviewers are supportive as compared to nonsupportive or neutral. Effects are in the moderate range. Interviewer support is also associated with fewer errors on nonsuggestive questions. Discussion focuses on implications for practice; directions for future research; identifying vulnerable subgroups; and underlying cognitive, social, and emotional mechanisms.

Are multiple-trial experiments appropriate for eyewitness identification studies? Accuracy, choosing, and confidence across trials

Eyewitness identification experiments typically involve a single trial: A participant views an event and subsequently makes a lineup decision. As compared to this single-trial paradigm, multiple-trial designs are more efficient, but significantly reduce ecological validity and may affect the strategies that participants use to make lineup decisions. We examined the effects of a number of forensically relevant variables (i.e., memory strength, type of disguise, degree of disguise, and lineup type) on eyewitness accuracy, choosing, and confidence across 12 target-present and 12 target-absent lineup trials (N = 349; 8,376 lineup decisions). The rates of correct rejections and choosing (across both target-present and target-absent lineups) did not vary across the 24 trials, as reflected by main effects or interactions with trial number. Trial number had a significant but trivial quadratic effect on correct identifications (OR = 0.99) and interacted significantly, but again trivially, with disguise type (OR = 1.00). Trial number did not significantly influence participants' confidence in correct identifications, confidence in correct rejections, or confidence in target-absent selections. Thus, multiple-trial designs appear to have minimal effects on eyewitness accuracy, choosing, and confidence. Researchers should thus consider using multiple-trial designs for conducting eyewitness identification experiments.

Parental Attachment and Children's Memory for Attachment-Relevant Stories

Despite evidence that parents' attachment is associated with children's memory, less is known about the mechanisms underlying this association or the contexts in which the association is most meaningful. The present study examined whether parents' attachment predicted children's memory for stories about attachment-related topics, whether the cohesiveness of children's stories mediated the association between attachment and memory, and whether the association varied by interview support at retrieval. Five- to 6-year-olds completed attachment-relevant stories while parents provided information about their romantic attachment. Children's stories were coded for cohesiveness. A week later, children's memory for their stories was tested by either a supportive or non-supportive interviewer. When the interview was non-supportive, greater parental avoidance was associated with poorer memory, whereas when the interview was supportive, greater parental avoidance was associated with fewer errors. Findings provide insight into the context under which parents' attachment is most influential in shaping children's memory.

Is There Consensus About Children's Memory and Suggestibility?

The modern scientific study of children's eyewitness memory was initially motivated, in important part, by the sensational preschool investigations and prosecutions of the 1980s and 1990s (e.g., the McMartin case, the Kelly Michaels case, the Country Walk case). These cases form the centerpiece of Professor Cheit's scholarly book, The Witch-Hunt Narrative. In recent years, researchers have made great strides in helping the legal system tackle some of the complex issues involved in child sexual abuse investigations. While commenting on Professor Cheit's book, we review areas of consensus regarding child forensic interviewing, areas of disconnect between scientific laboratory studies and needs of the legal system, and the potential effects of bias on the scientific enterprise relevant to Professor Cheit's treatise. Although we find that there is consensus in the field regarding a set of general principles, there is often room for disagreement in evaluating a particular case, and there is still much to be learned about how best to interview children when allegations of sexual abuse arise.

Interviewing Child Witnesses: Past and Future

Much of the improvement in child witness interviewing in England and Wales has been based on the findings of psychological research concerning memory and language. However, relatively little research has been conducted on the possible influence of interviewer style or manner. This article reviews the limited previous research on this topic and presents a new study. It seems that an authoritative interviewing style may increase children's errors to suggestive questions.

Getting to Know You: Familiarity, Stereotypes, and Children's Eyewitness Memory

The present study concerned how the acquisition of social information, specifically knowledge about personal characteristics, influences young children's memory and suggestibility. Effects of two sources of knowledge about a target person were systematically examined: familiarity and stereotypes. Children, aged 4-5 and 7-9 years (N = 145), were randomly assigned, per age group, to experimental conditions based on a familiarity (6 hours vs. no prior exposure) × stereotype (negative depiction as messy and clumsy vs. no stereotype) factorial design. Children then watched the target person engage in a target event (a series of contests) at a preschool ("Camp Ingrid"). The children's memory and suggestibility about the target person and target event were tested after a delay of 2 weeks. Results indicated that the negative stereotype resulted in an increase in children's correct responses both to free-recall stereotype-related questions (when children were unfamiliar with the target person) and to closed-ended questions overall (for younger children). However, the stereotype was associated with greater error to stereotype-related closed-ended questions. Moreover, familiarity increased children's accuracy to closed-ended questions. Implications for theory and application are discussed. Copyright © 2016 John Wiley & Sons, Ltd.

Impact of interviewers' supportive comments and children's reluctance to cooperate during sexual abuse disclosure

In the field of child sexual abuse (CSA) disclosure, many studies have been conducted on the impact of interviewers' questioning style, but few have examined the impact of interviewers' supportive comments on children's cooperative and reluctant disclosure of substantive details. This field study used a sample of children ranging from 4 to 13 years of age who have all disclosed CSA. The first objective was to examine if the interviewer's and the child's comments during CSA interviews would vary as a function of the use of the National Institute of Child Health and Human Development (NICHD) Protocol. The second objective was to identify the strongest correlates of the proportion of details disclosed by the children during forensic interviews. A total of 90 matched NICHD Protocol and non-Protocol interviews done by the same interviewers were audio-taped, transcribed, and coded using verbal subscales. The goal was to explore if differences exist between the interviewers' supportive and non-supportive comments as well as children's cooperative and reluctant statements during investigative interviews conducted prior to or after the NICHD Protocol training. Results of a MANCOVA showed that the use of the NICHD Protocol had no influence on interviewers' and children's demeanors. A hierarchical multiple regression analysis controlling for relevant variables (e.g., child's age and NICHD Protocol) showed that children's reluctance and interviewers' non-support were associated with a lesser proportion of details. Overall, these results indicate that in order to promote detailed disclosure of CSA, interviewers should decrease their non-supportive comments and learn to deal more effectively with children's reluctance during forensic interviews. As such, protocols and training should encourage investigative interviewers to devote more time identifying early signs of children's verbal reluctance and to understand the negative impact of non-supportive comments on the disclosure of substantive details.

Eliciting maltreated and nonmaltreated children's transgression disclosures: narrative practice rapport building and a putative confession

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 and nonmaltreated children responded similarly to the manipulations. Neither narrative practice rapport building nor a putative confession increased false reports.

Stress, interviewer support, and children's eyewitness identification accuracy

Few studies have investigated how stress affects eyewitness identification capabilities across development, and no studies have investigated whether retrieval context in conjunction with stress affects accuracy. In this study, one hundred fifty-nine 7- to 8- and 12- to 14-year-olds completed a high- or low-stress laboratory protocol during which they interacted with a confederate. Two weeks later, they attempted to identify the confederate in a photographic lineup. The lineup administrator behaved in either a supportive or a nonsupportive manner. Participants who experienced the high-stress event and were questioned by a supportive interviewer were most accurate in rejecting target-absent lineups. Results have implications for debates about effects of stress on eyewitness recall, how best to elicit accurate identifications in children, and developmental changes in episodic mnemonic processes.

Stress at encoding, context at retrieval, and children's narrative content

Research concerning the relations between stress and children's memory has been primarily correlational and focused on memory volume and accuracy. In the current study, we experimentally manipulated 7- and 8-year-olds' and 12- to 14-year-olds' experienced stress during a to-be-remembered event to examine the effects of stress on the content of their memory. We further manipulated the degree of interviewer support at retrieval to determine whether it moderated the effects of stress at encoding on memory. Children's age, gender, stress at encoding, and interviewer support all influenced the type of information included in their narrative reports. Most notably, across ages, children who experienced a more stressful event but were questioned in a supportive manner provided the largest ratio of terms representing internal states such as those about cognitions and emotions. Results suggest that how children process past events may be influenced by both the nature of the event itself and the context within which it is recalled.

Memorial consequences of testing school-aged children

A large literature shows that retrieval practice is a powerful tool for enhancing learning and memory in undergraduates (Roediger & Karpicke, 2006a). Much less work has examined the memorial consequences of testing school-aged children. Our focus is on multiple-choice tests, which are potentially problematic since they minimise retrieval practice and also expose students to errors (the multiple-choice lures). To examine this issue, second graders took a multiple-choice general knowledge test (e.g., What country did the Pilgrims come from: England, Germany, Ireland, or Spain?) and later answered a series of short answer questions, some of which corresponded to questions on the earlier multiple-choice test. Without feedback, the benefits of prior testing outweighed the costs for easy questions. However, for hard questions, the large increase in multiple-choice lure answers on the final test meant that the cost of prior testing outweighed the benefits when no feedback was provided. This negative testing effect was eliminated when children received immediate feedback (consisting of the correct answer) after each multiple-choice selection. Implications for educational practice are discussed.

The Effects of Repetition on Children's True and False Reports

As children are often called upon to provide testimony in court proceedings, determining the veracity of their statements is an important issue. In the course of investigation by police and social workers, children are often repeatedly interviewed about their experiences, though the impact of this repetition on children's true and false statements remains largely unexamined. The current study analysed semantic differences in children's truthful and fabricated statements about an event they had or had not participated in. Results revealed that children's truthful and fabricated reports differed in linguistic content, and that their language also varied with repetition. Discriminant analyses revealed that with repetition, children's true and false reports became increasingly difficult to differentiate using linguistic markers, though true reports were consistently classified correctly at higher rates than false reports. The implications of these findings for legal procedures concerning child witnesses are discussed.

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.

Police interviews with child sexual abuse victims: patterns of reporting, avoidance and denial

OBJECTIVE

The present study investigated 27 sexually abused children's reports about abuse given in the context of police interviews. All abuse cases had been verified (with, e.g., photographs or video films), proving that abuse had occurred.

METHOD

The interviews with the children were analyzed regarding amount and type of information reported, and the frequency of denial and avoidance. Furthermore, children's reporting on different interview occasions was investigated.

RESULTS

Children reported significantly more neutral information from the abusive acts per se than sexual information. The children were also highly avoidant and, on several occasions, denied that (documented) sexual acts had occurred. Furthermore, the second and third interviews generated twice as many (new) sexual details as the first interview. The children also produced more denials and avoidances at the first interview compared to subsequent interviews.

CONCLUSIONS

The present study indicates that sexually abused children may be highly resistant to reporting about the abuse in police interviews, and that two or three interviews may be needed to enable children to give complete and informative reports. It is of vital importance that professionals within the legal system be aware of this problem when conducting child interviews and when evaluating the reliability of child sexual abuse reports.

Assessing the effectiveness of the NICHD investigative interview protocol when interviewing French-speaking alleged victims of child sexual abuse in Quebec

OBJECTIVES

The study was designed to assess the effectiveness of the flexibly structured NICHD Investigative Interview Protocol for child sexual abuse (CSA) investigative interviews by police officers and mental health workers in Quebec. The NICHD Protocol was designed to operationalize "best practice" guidelines and to help forensic interviewers use open-ended prompts to facilitate free recall by alleged victims.

METHOD

A total of 83 interviews with 3- to 13-year-old alleged victims were matched with 83 interviews conducted by the same interviewers before they were trained to use the Protocol. Interviews were matched with respect to the children's ages, children-perpetrator relationships, and the types and frequency of abuse. Coders categorized each of the prompts used to elicit information about the abuse and tabulated the numbers of new forensically relevant details provided in each response.

RESULTS

Interviewers used three times as many open-ended prompts in Protocol interviews than in non-Protocol interviews, whereas use of all other types of questions was halved, and the total number of questions asked decreased by 25%. Protocol-guided interviews yielded more details than comparison interviews. The mean number of details per prompt increased from 3 to 5 details when the Protocol was used. Even with young children, interviewers using the Protocol employed more invitations to elicit forensically relevant details.

CONCLUSIONS

French-speaking investigators using the NICHD Protocol used open-ended prompts rather than focused questions when interviewing alleged victims. In addition, these interviewers needed fewer questions to get relevant information when using the Protocol.

PRACTICAL IMPLICATIONS

A French version of the NICHD Protocol is now available to police officers and social workers who investigate the alleged sexual abuse of young children in French-speaking countries. This French version allowed trained interviewers to increase the use of invitations and reduce the use of more focused and risky questions. When the number of questions was controlled, more central details and more details in total were obtained in Protocol interviews, because the average prompt elicited more detailed answers in Protocol interviews. However, learning to use the NICHD Protocol required extended training and continued feedback sessions to maintain the high quality of interviewing.

Socioemotional factors in child sexual abuse investigations

Two socioemotional factors were explored in association with children's production of forensic information during sexual abuse investigations: rapport building and interviewer's support. The study tested to what extent (a) the length and questioning style in the rapport-building session and (b) the level of support interviewers provided to the children, were associated with the amount of forensic details children provided in their investigation. These associations were explored for more talkative and less talkative children as well as for children of two age groups (4-6 and 7-9 years). A total of 71 forensic interviews of alleged victims of child sexual abuse were subject to a detailed psycholinguistic analysis. Results suggest that richer information in the child's responses is associated with a short and open style rapport-building session as well as with a higher level of interviewer's support. This association is especially marked for less talkative children who might be in special need of support and for whom the rapport with the interviewer might be more meaningful.

Repeated Interviews and Children's Memory

A crucial issue in the study of eyewitness memory concerns effects of repeated interviews on children's memory accuracy. There is growing belief that exposure to repeated interviews causes increased errors. In some situations, it may. Yet, several studies reveal increased accuracy with repeated interviewing, even when the interviews include misleading questions. We review repeated-interview research in relation to event veracity, interviewer bias, and delay. We conclude that when and how children are interviewed is at least as important for their accuracy as is how many times they are interviewed.

Trauma and memory: effects of post-event misinformation, retrieval order, and retention interval

The present study concerned effects of misinformation, retrieval order, and retention interval on eyewitness memory for a traumatic event (a vivid murder). Relations between misinformation acceptance and compliance were also examined. The classic three-stage misinformation paradigm (Loftus, 1979) was employed, with a multi-component recognition test added. Either immediately or 2 weeks after viewing a distressing film, 232 adults read a narrative (misleading or control) about the murder and then took a recognition test that tapped memory for central and peripheral details. Test-item order either matched the chronology of the film or was randomly determined. Significant misinformation effects were obtained. Moreover, control participants were more accurate in response to questions about central than peripheral information; however, this was not so for misinformed participants. Sequential but not random retrieval order resulted in a higher proportion of correct responses for central as opposed to peripheral misinformation questions. Compliance was significantly related to misinformation effects. Delay increased participants' suggestibility, impaired memory accuracy, and produced higher confidence ratings for misinformed participants compared to controls. Findings indicate that even for a highly negative event, adults' memory is not immune to inaccuracies and suggestive influences.
