Suggestibility of the child witness: a historical review and synthesis

Child witnesses' metamemory realism

This study investigated the degree of realism in the confidence judgments of 11 to 12-year-olds (41 girls and 40 boys) of their answers to questions relating to a short film clip showing a kidnapping event. Four different confidence scales were used: a numeric scale, a picture scale, a line scale and a written scale. The results demonstrated that the children showed a high level of overconfidence in their memories. However, no significant differences between the four confidence scales were found. Weak gender differences were found in that the girls were slightly, but significantly, better calibrated than the boys. In addition, although both boys and girls overestimated the total number of memory questions they had answered correctly, the boys gave higher estimates compared with the girls. In brief, the results indicate that, at least in the context investigated, 11-12 year-old children's confidence in and estimations of their own event memory show poor realism (overconfidence and overestimation). A comparison with previous research on adults indicates that 11 to 12-year-old children show noticeably poorer realism.

Children's memory for complex autobiographical events: Does spacing of repeated instances matter?

Often, when children testify in court they do so as victims of a repeated offence and must report details of an instance of the offence. One factor that may influence children's ability to succeed in this task concerns the temporal distance between presentations of the repeated event. Indeed, there is a substantial amount of literature on the "spacing effect" that suggests this may be the case. In the current research, we examined the effect of temporal spacing on memory reports for complex autobiographical events. Children participated in one or four play sessions presented at different intervals. Later, children were suggestively questioned, and then participated in a memory test. Superior recall of distributed events (a spacing effect) was found when the delay to test was 1 day (Experiment 1) but there was little evidence for a spacing effect when the delay was 1 week (Experiment 2). Implications for understanding children's recall of repeated autobiographical events are discussed.

Global gist extraction in children and adults

The DRM paradigm was used to examine the role of global gist extraction in producing false memories in children and adults. First-graders, third-graders, and adults watched a videotape of a woman reading seven DRM lists, and then took a recognition memory test. Blocked (vs random) presentation and instructions to attend to the theme of lists were manipulated to enhance gist processing. In the first experiment, blocked presentation increased false recognition relative to random presentation in adults but not in first-graders or third-graders. In the second experiment, instructions to attend to list themes increased false recognition in third-graders and not in adults or first-graders. The results suggest a developmental pattern in which children become more adept at global gist extraction as they get older. These results are consistent with fuzzy trace theory's prediction of better gist processing as children grow older.

[The influence of cognitive abilities, age and characteristics of their sexual abuse experience on the statement of the presumed victims]

OBJECTIVE

The goal of the present study was to examine the effects of children's age, cognitive abilities and the characteristics of their sexual abuse experience on the quantity of details revealed about the sexual abuse in an investigative interview as a function of the type of questions asked. METHOD VERSION: Transcripts of 37 investigative interviews conducted with children between 6 and 12 years of age were analyzed according to the type of interviewer questions used and the quantity of details given by the child. The children's cognitive abilities were measured using the vocabulary, information and block design subtests of the WISC-III.

RESULTS

Results of multiple regression analyses indicate that children's age and verbal abilities as well as their relationship with the perpetrator explain 50% of the variance of the mean number of details obtained from the child following open-ended interviewer questions.

CONCLUSION

The results of this study suggest that the quantity of details obtained during an investigative interview is influenced not only by children's age but also by their verbal skills and the child-perpetrator relationship.

Believing is seeing: how rumors can engender false memories in preschoolers

This study examined how an erroneous rumor circulated among preschoolers can influence their memory. One fourth of the children overheard a rumor from an adult conversation in which it was alleged that an event the children had not experienced themselves had occurred. A second fourth were the classmates of those who overheard the rumor. A third group had no exposure to the rumor. The remaining children actually experienced the event suggested by the rumor. One week later, the children were interviewed in either a neutral or a suggestive manner. Results from a second interview after a 2-week delay revealed that under both interview conditions, children who overheard the rumor, either from the adult conversation or during naturally occurring interactions with classmates, were as likely to report experiencing the rumored but nonexperienced event as were those who actually experienced it. Most reports of the rumored but nonexperienced event were in children's free recall and were accompanied by high levels of fictitious elaboration.

Testimony and interrogation of minors: Assumptions about maturity and morality

This article examines the legal histories and social contexts of testimony and interrogation involving minors, developmental research on suggestibility and judgment, interactions between development and legal/sociological contexts, and the reasoning behind how minors are treated in different legal contexts. The authors argue (a) that young witnesses, victims, and suspects alike possess youthful characteristics that influence their ability to validly inform legal processes, some of which were recently recognized by the Supreme Court as they apply to the juvenile death penalty, and (b) that consideration should be given to reforming current practices in the context of juvenile interrogation.

The influence of another's perspective on children's recall of previously misconstrued events

Children's abilities to reframe their memories of events after hearing another child's perspective of the same events were examined, and links between memory reframing, cognitive ability, and social competence were explored. Nine- to 11-year-olds (N = 79) were told to imagine that the events in a narrated story happened to them. Next, they heard another story that described either the same events (experimental condition) or unrelated events (control condition) from another child's perspective. The children in the experimental group reframed their memories in light of the alternative perspective, whereas the children in the control condition did not. Children with higher cognitive scores had higher memory reframing scores and received higher social competence ratings than children with lower cognitive scores.

False allegations of abuse and neglect when parents separate

OBJECTIVE

The 1998 Canadian Incidence Study of Reported Child Abuse and Neglect (CIS-98) is the first national study to document the rate of intentionally false allegations of abuse and neglect investigated by child welfare services in Canada. This paper provides a detailed summary of the characteristics associated with intentionally false reports of child abuse and neglect within the context of parental separation.

METHOD

A multistage sampling design was used, first to select a representative sample of 51 child welfare service areas across Canada. Child maltreatment investigations conducted in the selected sites during the months of October-December 1998 were tracked, yielding a final sample of 7,672 child maltreatment investigations reported to child welfare authorities because of suspected child abuse or neglect.

RESULTS

Consistent with other national studies of reported child maltreatment, CIS-98 data indicate that more than one-third of maltreatment investigations are unsubstantiated, but only 4% of all cases are considered to be intentionally fabricated. Within the subsample of cases wherein a custody or access dispute has occurred, the rate of intentionally false allegations is higher: 12%. Results of this analysis show that neglect is the most common form of intentionally fabricated maltreatment, while anonymous reporters and noncustodial parents (usually fathers) most frequently make intentionally false reports. Of the intentionally false allegations of maltreatment tracked by the CIS-98, custodial parents (usually mothers) and children were least likely to fabricate reports of abuse or neglect.

CONCLUSIONS

While the CIS-98 documents that the rate of intentionally false allegations is relatively low, these results raise important clinical and legal issues, which require further consideration.

The effects of prior knowledge on children’s memory and suggestibility

In this study, 5- and 6-year-olds were read a story and asked to recall its details. Two independent factors-prestory knowledge and poststory suggestions-were crossed to examine the effects on children's story recall. The results indicated that prestory social knowledge about the story protagonist as well as academic knowledge relating to the content of the story influenced the accuracy of children's recall immediately after the story presentation. Following the suggestive interview, children reported interviewer-provided social and academic misinformation to a greater extent when the misinformation was consistent with their prior knowledge. In contrast, children were more likely to refute misinformation that contradicted their academic knowledge. These findings are discussed in terms of the mechanisms underlying the knowledge-memory and knowledge-suggestibility linkages.

Theory of mind, inhibitory control, and preschool-age children's suggestibility in different interviewing contexts

The current study examined the relations among 3- to 5-year-olds' theory of mind, inhibitory control, and three measures of suggestibility: yielding to suggestive questions (yield), shifting answers in response to negative feedback (shift), and accuracy in response to misleading questions during a pressured interview about a live event. Theory of mind aided in the prediction of suggestibility about the live event, and inhibitory control was a moderator variable affecting the consistency of children's sensitivity to social pressure across situations. The findings indicate that theory of mind and inhibitory control predict children's suggestibility about a live event above and beyond yield, shift, and age and that the construct validity of shift may improve as children's inhibitory control develops.

Do jurors "know" what isn't so about child witnesses?

Are expert witnesses needed in child sexual abuse cases to educate jurors about children's memory, suggestibility, and reactions to abuse, or do jurors already know what such experts could tell them? To cast light on this question, we surveyed jurors and jury-eligible college students and compared their beliefs with what is known via scientific research regarding children's memory and ability to testify, reactions to interrogation, and reactions to sexual abuse. We also asked participants to infer results of four widely cited studies of children's suggestibility. Participants' beliefs were consistent with findings from research on some issues (e.g., that children can be led to claim that false events occurred) but diverged from the scientific consensus on other issues (e.g., whether children can remember painful events in infancy). Similarly, participants sometimes overestimated and sometimes underestimated the level of suggestibility observed in empirical studies. Individual differences in accuracy were related to participants' gender, education and ethnicity, and there was considerable disagreement among participants on many questions. Implications of findings for the admissibility of expert testimony in child abuse cases are discussed.

Planting misinformation in the human mind: A 30-year investigation of the malleability of memory

The misinformation effect refers to the impairment in memory for the past that arises after exposure to misleading information. The phenomenon has been investigated for at least 30 years, as investigators have addressed a number of issues. These include the conditions under which people are especially susceptible to the negative impact of misinformation, and conversely when are they resistant. Warnings about the potential for misinformation sometimes work to inhibit its damaging effects, but only under limited circumstances. The misinformation effect has been observed in a variety of human and nonhuman species. And some groups of individuals are more susceptible than others. At a more theoretical level, investigators have explored the fate of the original memory traces after exposure to misinformation appears to have made them inaccessible. This review of the field ends with a brief discussion of the newer work involving misinformation that has explored the processes by which people come to believe falsely that they experienced rich complex events that never, in fact, occurred.

Criminal investigations of child abuse: the research behind "best practices"

This article reviews the research relevant to seven practices considered by many to be among the most progressive approaches to criminal child abuse investigations: multidisciplinary team investigations, trained child forensic interviewers, videotaped interviews, specialized forensic medical examiners, victim advocacy programs, improved access to mental health treatment for victims, and Children's Advocacy Centers (CACs). The review finds that despite the popularity of these practices, little outcome research is currently available documenting their success. However, preliminary research supports many of these practices or has influenced their development. Knowledge of this research can assist investigators and policy makers who want to improve the response to victims, understand the effectiveness of particular programs, or identify where assumptions about effectiveness are not empirically supported.

Forensic examination of suspected child victims of sexual abuse in the UK: a personal view

Expert opinion in child abuse has received considerable bad press and currently public confidence in this area of medical practice is low. Media interest has focused most on the diagnosis of factitious illness. However doctors who examine children in respect of proceedings arising from suspected sexual abuse should be mindful this area is potentially just as problematic. Widely different rates of abnormal findings have been reported. At least in part this has reflected inconsistency in interpretation. Findings once assumed diagnostic of penetration are now recognised to occur in non-abused children. The practical difficulties of examining a reluctant child and achieving adequate visualisation of the hymen in relaxed state, are frequently underestimated. Where normal or non-specific findings are presented as "consistent with the alleged event" there is a high risk the court will perceive them to be significant. Guidelines have tended to lag behind existing knowledge and made inadequate differentiation between prepubertal and adolescent cases. They have also placed a high degree of reliance on statements from children without regard to the context in which any "disclosure" had arisen. Photodocumentation has important benefits, and limitations. Images may not display the true depth of field and are not the same as examining the child directly. Examination must remain the gold standard. There is a moral duty of care on the examining doctor to understand and clarify the status of findings dispassionately and with due regard to the level of the evidence base.

Detecting deception in children: an experimental study of the effect of event familiarity on CBCA ratings

The CBCA is the most commonly used deception detection. technique worldwide. Pezdek et al. (2004) used a quasi-experimental design to assess children's accounts of a traumatic medical procedure; CBCA ratings were higher for descriptions of familiar than unfamiliar events. This study tested this effect using an experimental design and assessed the joint effect of familiarity and veracity on CBCA ratings. Children described a true or a fabricated event. Half described a familiar event; half described an unfamiliar event. Two CBCA-trained judges rated transcripts of the descriptions. CBCA scores were more strongly influenced by the familiarity than the actual veracity of the event, and CBCA scores were significantly correlated with age. CBCA results were compared with results from other measures. Together with the results of K. Pezdek et al. (2004) these findings suggest that in its current form, CBCA is of limited utility as a credibility assessment tool.

Updating reactivated memories in infancy: I. Passive- and active-exposure effects

This study examined the vulnerability of infants' reactivated memories to modification. In three experiments, one hundred eight 3-month-olds learned to move a distinctive mobile by kicking. After the operant task was forgotten, its memory was recovered by a reactivation treatment. Immediately afterward, attempts were made to modify the reactivated memory by exposing infants to a novel mobile. Exposing the novel mobile immediately after the reactivation treatment did not affect the reactivated memory (Experiment 1). When exposure to the novel mobile was delayed for 24 hr, the novel mobile temporarily interfered with recognition of the original mobile, but did not modify the reactivated memory (Experiment 2). Only when the contingency was briefly associated with the novel mobile (an active-exposure procedure) was the reactivated memory modified (Experiment 3). These data reveal that infants' recently reactivated memories are surprisingly resistant to updating unless the operant contingency that established the original memory accompanies the new information.

The outbreak of mass allegations of Satanist child abuse in the parish of Rättvik, Sweden, 1670-71: two texts by Gustav J. Elvius

During recent decades, interpretation of mass allegations fo Satanist child abductions have challenged psychiatrists and mental health professionals in the Western world. It has been argued that a useful perspective on this phenomenon ay be gained from a study of historical parallels from countries such as Spain, Germany and Sweden. The texts translated below are an eyewitness account of the witch panic in Rättvik 1670-71 and a letter of 1671, both written by the Reverend Gustav Elvius.

"Intuitive" lie detection of children's deception by law enforcement officials and university students

Adults' ability to detect children's deception was examined. Police officers, customs officers, and university students attempted to differentiate between children who lied or told the truth about a transgression. When children were simply questioned about the event (Experiment 1), the adult groups could not distinguish between lie-tellers and truth-tellers. However, participants were more accurate when the children had participated in moral reasoning tasks (Experiment 2) or promised to tell the truth (Experiment 3) before being interviewed. Additional exposure to the children did not affect accuracy (Experiment 4). Customs officers were more certain about their judgments than other groups, but no more accurate. Overall, adults have a limited ability to identify children's deception, regardless of their experience with lie detection.

Entwicklungsveränderungen in Konformität und in kognitiven Folgen sozialer Beeinflussung

Zusammenfassung. Die vorliegende Studie beschäftigt sich mit Entwicklungsveränderungen bei sozialer Beeinflussung sowie deren Auswirkungen auf die Erinnerungsleistung. 89 Kinder im Alter von 7 bis 8 und 9 bis 10 Jahren wurden nach einer Woche zum Inhalt eines Kinderfilms befragt. Im ersten Interview wurde die Erinnerungsleistung über offene Fragen ermittelt. Anschließend wurde die Stärke des sozialen Einflusses von irreführenden und richtig lenkenden Suggestionen zusätzlich durch die Anwesenheit und das Antwortverhalten einer Verbündeten der Interviewerin variiert. Am nächsten Tag wurde die suggestive Befragung ohne Verbündete wiederholt. Eine Kontrollgruppe durchlief beide suggestiven Befragungen ohne Verbündete. Es zeigten sich deutliche Alterseffekte in der Fähigkeit sozialer Beeinflussung zu widerstehen: Während 7- bis 8-Jährige noch durch Suggestionen sowie zusätzlich durch die Verbündete beeinflussbar waren, bestand bei 9- bis 10-Jährigen nur noch ein Einfluss der Verbündeten. Dies zeigte sich auch in altersspezifischen Unterschieden in den Nachwirkungen der Befragungssituation mit der Verbündeten auf die spätere Befragung ohne Verbündete.

Inviting witnesses to speculate: effects of age and interaction on children's recall

Inviting speculation has been found to increase children's false recall. In this study, kindergartners and third graders saw a clown perform actions alone or in interaction with a child. Two weeks later, the speculation group recalled all actions and was asked to speculate on half the actions. The control group recalled all actions without speculating. Four weeks after the show, all children recalled all actions again. The speculation group gave more false answers to the speculated items than the control group. Surprisingly, older children tended to report as many if not more false responses than younger children, regardless of speculation. In the speculation group, there were fewer false answers for interactions than actions, but false answers did not differ across observation types in the control group. Finally, speculation did not affect free and cued recall differentially.

ERP indices of emotionality and semantic cohesiveness during recognition judgments

Event-related potentials (ERPs) were used to examine the impact of emotionality on false recognition. In Experiment 1, participants discriminated previously studied words from neutral and negatively valenced emotional foils. Emotional words elicited a more positive ERP than did neutral words and emotional foils were falsely recognized more often than neutral foils. In Experiment 2, the hypothesis that emotionality-based false recognition is due to the semantic cohesiveness of emotional words was tested by including a highly associated but emotionally neutral category (animals). It was emotional and not animal foils that elicited greater positivity in the ERP and increased false positive response. These data provide little support for semantic cohesiveness as the basis for false recognition effects, but are consistent with the view that the salience of emotional words can be falsely attributed to familiarity in the context of a recognition task.

Culture and children's cosmology

In this investigation, we examined children's knowledge of cosmology in relation to the shape of the earth and the day-night cycle. Using explicit questioning involving a choice of alternative answers and 3D models, we carried out a comparison of children aged 4-9 years living in Australia and England Though Australia and England have a close cultural affinity, there are differences in children's early exposure to cosmological concepts. Australian children who have early instruction in this domain were nearly always significantly in advance of their English counterparts. In general, they most often produced responses compatible with a conception of a round earth on which people can live all over without falling off. We consider coherence and fragmentation in children's knowledge in terms of the timing of culturally transmitted information, and in relation to questioning methods used in previous research that may have underestimated children's competence.

Interviewing youthful suspects in alleged sex crimes: a descriptive analysis

OBJECTIVE

To introduce and evaluate a structured interview protocol designed for investigative interviews of youthful alleged perpetrators of child sexual abuse.

METHOD

Seventy-two alleged perpetrators ranging from 9 to 14 years of age (M = 12 years) were interviewed by 1 of 13 experienced youth investigators, employed by the Israeli Ministry of Labour and Social Affairs, about incidents that had been reported by alleged victims. All interviews were conducted as part of the investigators' regular work and followed the structured interview guide appended to this article.

RESULTS

Interviewers questioned older and younger children similarly, but addressed fewer invitations, directive questions, and option-posing prompts to suspects who denied the allegations than to those who partially or fully admitted them. The total number of details provided by the suspects did not vary depending on their age or whether or not they fully or partially admitted the allegations. In both cases, more information was elicited using invitations rather than suggestive or option-posing prompts.

CONCLUSION

Contrary to expectations, suspects who at least partially admitted their involvement provided considerable amounts of information and were very responsive to free recall prompts, although interviewers used more risky (potentially error-inducing) prompts when interviewing suspects rather than alleged victims.

Changes in reality monitoring and episodic memory in early childhood

The purposes of this research were to examine the developmental relation between reality monitoring and episodic memory, to link reality monitoring to autobiographical memory by using extended naturalistic events, and to examine prefrontal functioning as a potential contributor to development in reality monitoring and episodic memory. In Experiment 1, 4-year-olds were worse than 6- or 8-year-olds at reality monitoring after a week delay, despite the fact that they remembered more about real than imagined events and remembered different aspects of each. In Experiments 2 and 3, reality monitoring and episodic memory were evaluated for 4- and 6-year-olds immediately after the events occurred and, in Experiment 3, again after a week delay. Reality monitoring was at higher levels for both age groups, but age differences remained. These data suggest that preschoolers' difficulties with reality monitoring result from a combination of episodic memory deficits and strategic differences. In addition, correlation analyses more directly linked preschoolers' reality monitoring to episodic memory and supported the hypothesis that episodic memory development is related to prefrontal functioning.

“It’s magic!” The effects of presentation modality on children’s event memory, suggestibility, and confidence judgments

The current study investigated the influence of presentation modality (live, video, and slide show) on children's memory, suggestibility, recognition, and metamemorial monitoring processes. A total of 270 children in three age groups (5- and 6-year-olds, 7- and 8-year-olds, and 9- and 10-year-olds) watched a magic show and were questioned about it 1 week later. The live show yielded more correct answers to nonleading questions, higher resistance to misleading questions, and better recognition memory than did the video condition, which in turn resulted in better performance than did the slide show. Although presentation modality raised the general level of memory performance, the effects were equally strong in all age groups and did not affect memory phenomena such as the size of the misinformation effect and confidence judgments.

Detecting deception in children: event familiarity affects criterion-based content analysis ratings

Statement Validity Assessment (SVA) is a comprehensive credibility assessment system, with the Criterion-Based Content Analysis (CBCA) as a core component. Worldwide, the CBCA is reported to be the most widely used veracity assessment instrument. We tested and confirmed the hypothesis that CBCA scores are affected by event familiarity; descriptions of familiar events are more likely to be judged true than are descriptions of unfamiliar events. CBCA scores were applied to transcripts of 114 children who recalled a routine medical procedure (control) or a traumatic medical procedure that they had experienced one time (relatively unfamiliar) or multiple times (relatively familiar). CBCA scores were higher for children in the relatively familiar than the relatively unfamiliar condition, and CBCA scores were significantly correlated with age. Results raise serious questions regarding the forensic suitability of the CBCA for assessing the veracity of children's accounts.
