Detecting children's true and false denials of wrongdoing: Effects of question type and base rate knowledge

One common and unfortunately overlooked obstacle to the detection of sexual abuse is non-disclosure by children. Non-disclosure in forensic interviews may be expressed via concealment in response to recall questions or via active denials in response to recognition (e.g., yes/no) questions. In two studies, we evaluated whether adults' ability to discern true and false denials of wrongdoing by children varied as a function of the types of interview question the children were asked. Results suggest that adults are not good at detecting deceptive denials of wrongdoing by children, even when the adults view children narrate their experiences in response to recall questions rather than provide one word answers to recognition questions. In Study 1, adults exhibited a consistent “truth bias,” leading them toward believing children, regardless of whether the children's denials were true or false. In Study 2, adults were given base-rate information about the occurrence of true and false denials (50% of each). The information eliminated the adults' truth bias but did not improve their overall detection accuracy, which still hovered near chance. Adults did, however, perceive children's denials as slightly more credible when they emerged in response to recall rather than recognition questions, especially when children were honestly denying wrongdoing. Results suggest the need for caution when evaluating adults' judgments of children's veracity when the children fail to disclose abuse.     

Children's episodic and generic reports of alleged abuse

With the present data, we explored the relations between the language of interviewer questions, children's reports, and case and child characteristics in forensic interviews. Results clearly indicated that the type of questions posed by interviewers—either probing generic or episodic features of an event—was related to the specificity of information reported by children. Further, interviewers appeared to adjust their questioning strategies based on the frequency of the alleged abuse. Children alleging single instances of abuse were asked more episodic questions than those alleging multiple abuses. In contrast, children alleging multiple incidents of abuse were asked a greater proportion of generic questions. Given that investigators often seek forensically relevant episodic information, it is recommended that training for investigators focus on recognition of prompt selection tendencies and developing strategies for posing non‐suggestive, episodically focused questions.

The Effects of Adult Suggestion and Child Consistency on Young Children's Reports1

The purpose of the present study was to contrast the effects of children's response consistency and adult leading questions in a structured memory interview. Children (N = 70) who viewed a 2‐min video clip were asked 3 questions (leading, misleading, and neutral) related to the video. Children's responses (assent vs. deny) were predicted by the type of question asked by the adult (neutral, leading, and misleading), but not by the previous response given by the child or the child's age in months. Specifically, children assented the least often to misleading questions. Accuracy was predicted by both question type and in the last question–answer pair, children's previous response accuracy. These findings are discussed with relation to interview dynamics.     

Self‐Reported Current Practices in Child Forensic Interviewing: Training,Tools, and Pre‐Interview Preparation

In child sexual abuse investigations, forensic interviewers within the Child Advocacy Center (CAC) model serve as neutral fact‐finders for a team of professionals tasked with investigating and intervening in cases of alleged child sexual abuse. Although empirical evidence has led to the development of best‐practice techniques and protocols, there is currently no universally adopted protocol in the field. The present research gathered detailed information from a national sample of real‐world child forensic interviewers about their training and current practices, with a specific focus on assessing the information interviewers typically review prior to conducting child forensic interviews. Most notably, the survey revealed a lack of uniformity in interviewing protocols adopted and pre‐interview preparation practices. Although rare, some interviewers reported using an allegation‐blind interviewing approach, highlighting the need for future research on this and other under‐studied techniques.

Does drawing facilitate older children's reports of emotionally laden events?

Although it is well‐established that drawing about an event increases the amount of verbal information that young children provide during an interview, it is unclear whether drawing continues to facilitate children's reports as they get older. In the present experiment, 90 children, ranging from 5‐ to 12‐years old, were asked to draw and tell or to just tell about emotional events they had experienced. Children of all ages reported more information when asked to draw and tell rather than to tell only. Drawing had no negative effect on the accuracy of children's accounts. Drawing also increased the number of open‐ended questions and minimal responses that interviewers used. We conclude that drawing may be a useful tool in clinical and forensic settings with children of all ages; it increases the amount of information that children report and the number of appropriate questions that interviewers ask.

Favourable and unfavourable conditions for children's confidence judgments

Two studies are presented in which favourable and unfavourable conditions for children's meta‐cognitive monitoring processes are examined. Previously reported findings have shown that especially children's uncertainty monitoring (in contrast to certainty monitoring) poses specific problems for children in their elementary school years. When interviewing children about an observed event, answerable and unanswerable questions in two question formats (unbiased and misleading) were used, and 8‐ and 10‐year‐old children as well as adults were asked to rate their confidence on a three‐point scale concerning each response. Results of Study 1 show that accuracy instructions and the option to answer with ‘I don't know’ inflate children's level of confidence because uncertain answers are withheld. Results of Study 2 revealed that children's difficulty with uncertainty monitoring may lie in a cognitive overload during the interview because immediate confidence judgments were less precise and less adequate compared with delayed confidence judgments. Participants' rating of their uncertainty after having erroneously provided an answer to an unanswerable question proved that children aged 8 years and older are able to experience and report levels of uncertainty but, as was shown for answerable questions, these emerging competencies are dependent on favourable task conditions.     

The Effects of Accuracy Motivation on Children's and Adults' Event Recall,Suggestibility, and Their Answers to Unanswerable Questions

This study investigated children's and adults' event recall accuracy and suggestibility effects when participants' accuracy motivation was manipulated. A total of 240 participants (6-, 7-, and 8-year-olds, and adults) were shown a video and later asked 4 types of questions: answerable questions, both open-ended and strongly misleading, and unanswerable questions, both open-ended and strongly misleading. Participants were either (a) rewarded with a token for every correct answer (high accuracy motivation, Free Report Plus Incentive condition), (b) explicitly given the option of answering with "don't know" when unsure (medium accuracy motivation, Free Report condition), or (c) asked to provide an answer to every question, even when they were not sure or had to guess or both (low accuracy motivation, Forced Report condition). The condition with the high accuracy motivation yielded the highest recall accuracy scores for answerable open-ended and misleading questions. For unanswerable questions, even the youngest age group was able to increase the number of appropriate "don't know" answers when highly motivated to be accurate, but a misleading question format undermined these abilities. The results highlight important interactions between social (accuracy motivation) and cognitive factors (metacognitive monitoring processes) in children's formal interviewing.     

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.     

Skill in Interviewing Reduces Confirmation Bias

Interviewers given prior information are biassed to seek it from interviewees. We examined whether the detrimental impact of this confirmation bias in terms of leading question use was moderated by interviewers' demonstrated ability to adhere to open questions. We classified interviewers' adherence as ‘good’ or ‘poor’ in an independent interview before they interviewed children about a staged event. Half the interviewers were given biassing true and false information about the event; half were given no information. As predicted, only poor interviewers showed the effect of bias. Poor interviewers asked fewer open questions in the biassed condition than the non‐biassed condition; good interviewers asked the same (high) proportion of open questions in both conditions. Poor interviewers asked more leading questions in the biassed condition than the non‐biassed condition; good interviewers asked the same (low) proportion of leading questions in both conditions. These results demonstrate that interviewers' skill in adhering to open questions reduces the detrimental impact of confirmation bias on question type. Copyright © 2012 John Wiley & Sons, Ltd.     

Transmitting pro‐environmental behaviours to the next generation: A comparison between Germany and Japan

The present study examined the processes by which children acquire pro‐environmental behaviours in different cultures. Our focus was on parental influence. Several studies have been conducted on adults' environmental behaviours; however, we know little about how children's environmental attitudes and behaviours are formed. We conducted a questionnaire survey with elementary school children and one of their parents in Germany and Japan. Two hundred and twenty‐one pairs participated in Germany and 365 in Japan. The results of structural equation modelling showed that parents' behaviours affected children's environmental behaviours directly and also via the subjective norm (the children's experienced expectations of their parents). A comparison of the two countries revealed that hypothesized cultural differences between the impact of personal norms and subjective norms were clearer for adults. The results also showed that the effects of subjective norms were stronger for children, indicating that children are more likely to be influenced by expectations of others. The results of the study suggest that for promoting children's environmental behaviours, showing the behaviours in daily life would be most effective.     

Correspondence between children's and adults' ratings of stimulant-induced changes in ADHD behaviours in a crossover trial with medication-naive children

Correspondence between children's and adults' ratings of changes in ADHD behaviours was investigated in a paediatric ADHD stimulant crossover trial. Thirty-one children completed an ADHD self-report scale each week, and comparisons were made with an ADHD questionnaire completed by adults (combined parent and teacher ratings). Children's and adults' ratings demonstrated good internal consistency, were significantly associated with the assessment of ADHD behaviours in the placebo condition and showed comparable responsiveness to stimulants at the group level. Furthermore, a large and significant correlation was detected between the two sets of informants' ratings of changes from placebo to both methylphenidate and dextroamphetamine high-dosage conditions, but not from placebo to low-dosage conditions. Agreement in the categorization of best stimulant condition for individual children was significant, but modest from a clinical perspective. The results indicate that children's ratings correspond adequately with adults' ratings, and thus appear to be a complementary outcome measure.     

“Blind” interviewing: Is ignorance bliss?

Current investigative interviewing guidelines [e.g., Technical Working Group: Eyewitness evidence. (1999). Eyewitness evidence: A guide for law enforcement. U.S. Department of Justice, Office of Justice Programs, National Institute of Justice. Retrieved from https://www.ncjrs.gov/pdffiles1/nij/178240.pdf] suggest that interviewers review available case information prior to conducting a witness interview. The present study investigated the effect of interviewers’ pre-interview awareness of crime details on eyewitnesses’ memory and interviewer behaviour shortly after a mock crime or a week later. Results indicate that blind interviewers with no knowledge about the crime elicited more correct information than those who were correctly informed about the crime. Differences in interviewer behaviour emerged only in the very first question of the interview: Blind interviewers were more likely to begin the interview with a non-suggestive question than the informed interviewers. Blind interviewers also recalled more details than the informed interviewers when asked to generate a report after the witness interview documenting the witness’ account.     

Suspects' consistency in statements concerning two events when different question formats are used

Lie detection research has typically focused on reports about a single event. However, in many forensic and security contexts, suspects are likely to report on several events, some of them may be untruthful. This presents interviewers with the challenge of detecting which reports are true and which are not. Varying question format in a second interview, we examined differences in liars' and truth‐tellers' statement consistency about two events. One hundred and fifty participants viewed a meeting in which a noncritical and a critical event were discussed. Truth‐tellers were instructed to be honest in their reports about both events, whereas liars had to lie about the critical event. In the first interview, all participants provided a free recall account. In a second interview, participants either gave another free recall account or responded to specific questions presented sequentially (concerning one event at a time) or nonsequentially (concerning both events simultaneously). Liars' accounts featured fewer repetitions than truth‐tellers for both events, particularly in response to questions presented in nonsequential order. The implications for the use of this question format are discussed.     

Are two heads better than one? Peer support and children's eyewitness reports

This study examined the effects of peer support on children's event reports. In Experiment 1, 48 children aged between 5 and 10 years who had been scheduled for a school dental visit involving an invasive procedure were interviewed about it 2–4 days later. Children were interviewed alone, with an informed peer (who had also recently had a dental appointment), or with an uninformed peer. Anxiety was assessed both prior to the dental appointment and at the time of the recall interview. Peer support did not influence children's anxiety or the amount or the accuracy of information reported in prompted recall. However, younger children interviewed alone were significantly more likely to be misled than those interviewed in the presence of a support child. In Experiment 2, children aged between 5 and 7 years took part in a neutral event contrived for the study. They were interviewed about it 3 days later, either alone or with an informed or uninformed support child present. The support child was encouraged to take an active part in the interview and to help the target child to describe what happened. Peer support did not influence the recall of the target child in either prompted recall or in response to questions. However, together the target and informed support children reported more information than did children interviewed alone or with uninformed support. © 1997 John Wiley & Sons, Ltd.     

The effect of question repetition within interviews on young children's eyewitness recall

This study investigated the influence of question repetition and question type (answerable, unanswerable, or opinion seeking) on children's recall. A total of 136 children (5-, 7-, and 9-year-olds) watched a live 15-min presentation. One week later, the children were asked 20 questions that were repeated an additional two times within the interview. Accuracy of children's responses to unanswerable questions declined with repetition. Children were more likely to change a response to an unanswerable question than to an answerable question. Overall, children maintained the same answers to only three-quarters of the repeated questions. The most common pattern of change was for children to change their answer the second time a question was asked and then to maintain that answer when questioned again. The high percentage of changed answers within a single interview has important implications for forensic interviewing.     

WORD EXPOSURE CONDITIONS AND PRESCHOOLERS' NOVEL WORD LEARNING DURING SHARED STORYBOOK READING

In this experiment, 23 preschool children participated in two adult-child shared storybook reading sessions over a 1-week period. The objective was to characterize the influence of various conditions of word exposure upon children's receptive and expressive learning of novel words occurring within storybook reading interactions. Specifically, the effects of two contrasting conditions were examined: (a) adults' questioning versus labeling of novel words, and (b) adults' use of perceptual versus conceptual questions about novel words. Results suggested that adults' labeling of novel words facilitated children's receptive word learning more so than questioning; however, this effect was not observed for expressive word learning. Results also suggested no difference in receptive or expressive word learning as a result of conceptual versus perceptual questions. Implications of these findings are discussed.
