Children's suggestibility for an instance of a repeated event versus a unique event: the effect of degree of association between variable details

Are children who experience an event repeatedly more suggestible about an instance of the event than children who experience it once? Researchers have answered this question both in the affirmative and in the negative. In this study, we hypothesized that the degree of association between details that changed across instantiations of the event would help to explain the discrepancy. Preschoolers (4- and 5-year-olds) and first graders (6- and 7-year-olds) participated in either a single play session or four repeated play sessions, each of which contained 16 critical details. Across play sessions in the repeat-event condition, half of the critical details were associated and half were not associated. During a biasing interview 2 weeks later, children were misinformed about half of the critical details. The next day, children answered free and cued recall questions about the target play session. Among older children, repeat-event participants were more suggestible than single-event participants, especially for high-association details. Among younger children, repeat-event participants were more suggestible than single-event participants for low-association details. Consistent with some current theories of children's memory, older children were more suggestible than younger children.     

Memory and suggestibility in maltreated children: age,stress arousal,dissociation, and psychopathology

The present study was designed to assess children's memory and suggestibility in the context of ongoing child maltreatment investigations. One hundred eighty-nine 3-17-year-olds involved in evaluations of alleged maltreatment were interviewed with specific and misleading questions about an anogenital examination and clinical assessment. For the anogenital examination, children's stress arousal was indexed both behaviorally and physiologically. For all children, individual-difference data were gathered on intellectual and short-term memory abilities, general psychopathology, and dissociative tendencies. Interviewers' ratings were available for a subset of children concerning the amount of detail provided in abuse disclosures. Results indicated that general psychopathology, short-term memory, and intellectual ability predicted facets of children's memory performance. Older compared to younger children evinced fewer memory errors and greater suggestibility resistance. Age was also significantly related to the amount of detail in children's abuse disclosures. Neither dissociation nor stress arousal significantly predicted children's memory. Implications for understanding maltreated children's eyewitness memory are discussed.     

Assessing the effects of misinformation on children's recall: how and when makes a difference

In two experiments children aged between 4 and 5 years and 7 and 8 years, respectively, participated in a real‐life event and were exposed to misleading questions immediately afterwards. The effects of variables relating to both the presentation of the misinformation and to the assessment of suggestibility were examined both immediately and following delays of 1 week (Experiment 1) or both 1 week and 1 month (Experiment 2). Older children were less suggestible than younger. Children were less suggestible when suggestibility was assessed in recall questions rather than misleading questions, less suggestible when information was central rather than peripheral and when the misinformation contradicted rather than supplemented the original event, and less suggestible over time in the absence of further suggestions. Providing cues had a small effect in enhancing resistance to the misinformation, but only when children were tested immediately. Embedding suggestions in a narrative context and repeating suggestions within a session led to greater suggestibility for both age groups, and repeating suggestions following a 1‐month delay had a particularly marked effect for the younger children. These findings are consistent with the view that suggestibility effects depend on the strength of the memory trace for the original information as well as that for the suggestion. How suggestibility is assessed is, however, also important and children's responses to misleading questions may not reflect their memory for the original event.

Confidence judgments in children's and adults' event recall and suggestibility

The present work investigated the role of children's and adults' metacognitive monitoring and control processes for unbiased event recall tasks and for suggestibility. Three studies were conducted in which children and adults indicated their degree of confidence that their answers were correct after (Study 1) and before (Study 2) answering either unbiased or misleading questions or (Study 3) forced-choice recognition questions. There was a strong tendency for overestimation of confidence regardless of age and question format. However, children did not lack the principal metacognitive competencies when these questions were asked in a neutral interview. Under misleading questioning, in contrast, children's monitoring skills were seriously impaired. Within each age group, better metacognitive differentiation was positively associated with recall accuracy in the suggestive interview.     

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.     

Developmental differences in the effects of repeated interviews and interviewer bias on young children's event memory and false reports

The present study investigated developmental differences in the effects of repeated interviews and interviewer bias on children's memory and suggestibility. Three- and 5-year-olds were singly or repeatedly interviewed about a play event by a highly biased or control interviewer. Children interviewed once by the biased interviewer after a long delay made the most errors. Children interviewed repeatedly, regardless of interviewer bias, were more accurate and less likely to falsely claim that they played with a man. In free recall, among children questioned once after a long delay by the biased interviewer, 5-year-olds were more likely than were 3-year-olds to claim falsely that they played with a man. However, in response to direct questions, 3-year-olds were more easily manipulated into implying that they played with him. Findings suggest that interviewer bias is particularly problematic when children's memory has weakened. In contrast, repeated interviews that occur a short time after a to-be-remembered event do not necessarily increase children's errors, even when interviews include misleading questions and interviewer bias. Implications for developmental differences in memory and suggestibility are discussed.     

Source-monitoring training facilitates preschoolers' eyewitness memory performance

Preschool children are more susceptible to misleading postevent information than are older children and adults. One reason for young children's suggestibility is their failure to monitor the source of their memories, as in, for example, discriminating whether an event was seen live versus on television. The authors investigated whether source-monitoring training would decrease preschoolers' suggestibility. Thirty-six 3-4-year-olds observed target live and video events and were then given source-monitoring or recognition (control) training on nontarget events. Following training, all children answered 24 misleading and nonmisleading target-event questions. Children given source-monitoring training were more accurate than control group children in response to misleading and nonmisleading yes-no questions and in response to nonmisleading, open-ended questions. Implications for strategy development, dual representation, and child witness interviewing are discussed.     

Does the nature of the experience influence suggestibility? A study of children's event memory

Two experiments examined the effects of event modality on children's memory and suggestibility. In Experiment 1, 3- and 5-year-old children directly participated in, observed, or listened to a narrative about an event. In an interview immediately after the event, free recall was followed by misleading or leading questions and, in turn, test recall questions. One week later children were reinterviewed. In Experiment 2, 4-year-old children either participated in or listened to a story about an event, either a single time or to a criterion level of learning. Misleading questions were presented either immediately or 1 week after learning, followed by test recall questions. Five-year-old children were more accurate than 3-year-olds and those participating were more accurate than those either observing or listening to a narrative. However, method of assessment, level of event learning, delay to testing, and variables relating to the misled items also influenced the magnitude of misinformation effects.     

Event frequency and children's suggestibility: a study of cued recall responses

Research examining the effect of repeated experience on children's suggestibility for particular kinds of information has produced differing results. In one study, responses to recognition questions revealed heightened suggestibility for variable details in children who repeatedly experienced an event compared to children who experienced an event once. In other studies, no such effect was found with cued recall. In this study, 4–5‐year old children engaged in one or four play sessions. Children were later given a biasing interview wherein half of the details were incorrectly represented. Children were then given a final memory test using free and cued recall prompts that was preceded by one of three instruction types: no special instructions, moderate instructions, or opposition instructions. Children in the repeated‐event condition were more suggestible than those in the single‐event condition, regardless of instructions. No significant differences in suggestibility were found across instructions conditions. Copyright © 2004 John Wiley & Sons, Ltd.     

Children's false memory and true disclosure in the face of repeated questions

The current study was designed to investigate children's memory and suggestibility for events differing in valence (positive or negative) and veracity (true or false). A total of 82 3- and 5-year-olds were asked repeated questions about true and false events, either in a grouped order (i.e., all questions about a certain event asked consecutively) or in a nongrouped order (i.e., questions about a certain event were interspersed with questions about other events). Interviewer gender was also varied. Individual differences, including attachment style, inhibition, and behavioral adjustment, were examined as potential predictors of memory and suggestibility. Results revealed significant age, valence, and veracity effects on children's memory reports. Path analysis demonstrated that individual differences in behavioral problems and inhibitory ability predicted children's provision of inaccurate information. Implications for psychological theory and legal application are discussed.     

Source monitoring reduces the suggestibility of preschool children

The relation between source monitoring and suggestibility was examined among preschool children. Thirty-two 3- to 5-year-olds were simultaneously presented with a brief story in two different modalities, as a silent video vignette and a spoken narrative. Each modality presented unique information about the story, but the information in the two versions was mutually compatible. The children were then asked a series of questions, including questions about the source (modality) of story details, and leading questions about story details (to assess suggestibility). Performance on the source-monitoring questions was highly correlated with the ability to resist suggestion. In addition, children who were asked source-monitoring questions prior to leading questioning were less susceptible to suggestion than were those who were asked the leading questions first. This study provides evidence that source monitoring can play a causal role in reducing the suggestibility of preschool children.     

"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.     

Effects of information type on children’s interrogative suggestibility: is Theory-of-Mind involved?

This research was aimed at learning more about the different psychological mechanisms underlying children’s suggestibility to leading questions, on the one hand, and children’s suggestibility to negative feedback, on the other, by distinguishing between interview questions concerning different types of information. Results showed that, unlike the developmental pattern of children’s suggestibility to leading questions, the developmental pattern of children’s suggestibility to negative feedback differed depending on whether the interview questions concerned external facts (physical states and events) or internal facts (mental states and events). This difference was not manifested in response to questions concerning central versus peripheral facts. Results are interpreted in terms of the hypothesis that children’s suggestibility to negative feedback is differently affected by “Theory-of-Mind” abilities than children’s suggestibility to leading questions. Further research is needed in order to test this hypothesis.     

Children's eyewitness reports after exposure to misinformation from parents

This study examined how misleading suggestions from parents influenced children's eyewitness reports. Children (3 to 8 years old) participated in science demonstrations, listened to their parents read a story that described experienced and nonexperienced events, and subsequently discussed the science experience in two follow-up interviews. Many children described fictitious events in response to open-ended prompts, and there were no age differences in suggestibility during this phase of the interview. Accuracy declined markedly in response to direct questions, especially for the younger children. Although the older children retracted many of their false reports after receiving source-monitoring instructions, the younger children did not. Path analyses indicated that acquiescence, free recall, and source monitoring all contribute to mediating patterns of suggestibility across age. Results indicate that judgments about the accuracy of children's testimony must consider the possibility of exposure to misinformation prior to formal interviews.     

Children in Asian cultures say yes to yes-no questions: Common and cultural differences between Vietnamese and Japanese children

We investigated whether children's response tendency toward yes-no questions concerning objects is a common phenomenon regardless of languages and cultures. Vietnamese and Japanese 2- to 5-year-old (N = 108) were investigated. We also examined whether familiarity with the questioning issue has any effect on Asian children's yes bias. As the result, Asian children showed a yes bias to yes-no questions. The children's response tendency changes dramatically with their age: Vietnamese and Japanese 2- and 3-year-olds showed a yes bias, but 5-year-olds did not. However, Asian 4-year-olds also showed a yes bias only in the familiar condition. Also, Asian children showed a stronger yes bias in the familiar condition than the unfamiliar condition. These two findings in Asian children were different from the previous finding investigated North American children (Fritzley & Lee, 2003). Moreover, there was a within-Asian cross-cultural difference. Japanese children showed different response tendencies, which were rarely observed in Vietnamese children. Japanese 2-year-olds and some 3-year-olds showed a "no answer" response: they tended not to respond to an interviewer's questions. Japanese 4- and 5-year-olds also showed an "I don't know" response when they were asked about unfamiliar objects. Japanese children tended to avoid a binary decision. We discussed the cross-cultural differences.     

Automatic and intentional processes in children's eyewitness suggestibility

This research investigated the contribution of automatic and intentional memory processes to suggestible responses in 5- and 9-year-old children. Children were presented with an event followed the next day by a postevent summary containing misleading suggestions that were either read to participants or were self-generated in response to semantic and perceptual cues. All children were then given both a standard test and a modified forced-choice recognition memory test under inclusion and exclusion instruction conditions. On the standard test, both age groups were suggestible with the magnitude of these effects greater in the inclusion condition. Children performed more poorly on misled-generated items compared to misled-read items in the inclusion condition, but the opposite was the case under exclusion instructions. On the modified test, only 5-year-old children were found to be suggestible. Process dissociation analyses revealed that both automatic and intentional processes influenced misinformation acceptance, but that suggestibility was predominantly due to automatic processes.     

3～5岁幼儿暗示感受性与压力的关系:抑制性控制的调节效应

本研究在已有研究的基础上进一步探讨认知因素与外源性因素对儿童暗示感受性的交互作用。文章通过在访谈过程中设置不同水平的压力反馈,选用自编的儿童视觉暗示感受性测试材料及一系列抑制性控制实验任务,考查了儿童抑制性控制对压力和暗示感受性关系的调节作用。结果表明:(1)3～5岁幼儿的暗示感受性随着年龄的增长显著降低。(2)压力影响3～5岁幼儿的暗示感受性水平,压力越大,儿童的暗示感受性越强。(3)抑制性控制对压力与暗示感受性的关系具有显著的调节作用,压力对暗示感受性的影响会随着幼儿抑制性控制水平的提高而不断减弱。对于抑制性控制水平低的儿童来说,压力能正向预测其暗示感受性;但对于抑制性控制水平高的儿童来说,压力并不能显著预测其暗示感受性。     

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.     

Reducing child witnesses' false reports of misinformation from parents.

This study explored whether a source-monitoring training (SMT) procedure, in which children distinguished between events they recently witnessed versus events they only heard described, would help 3- to 8-year-olds to report only experienced events during a target interview. Children (N = 132) who witnessed science demonstrations and subsequently heard their parents describe nonexperienced events received SMT before or after a forensic-style interview. SMT reduced the number of false reports that 7- and 8-year-old children reported in response to direct questions but had no impact on the performance of younger children. Combined with earlier results, these data suggest a transition between 3 and 8 years of age in the strategic use of source-monitoring information to support verbal reports, such that only 7- and 8-year-olds generalize training to a difficult memory task that does not include mention of specific alternative sources.
