The Role of executive function in children\u27s source monitoring with varying retrieval strategies

Previous research on the relationship between executive function and source monitoring in young children has been inconclusive, with studies finding conflicting results about whether working memory and inhibitory control are related to source-monitoring ability. In this study, the role of working memory and inhibitory control in recognition memory and source monitoring with two different retrieval strategies were examined. Children (N = 263) aged 4–8 participated in science activities with two sources. They were later given a recognition and source-monitoring test, and completed measures of working memory and inhibitory control. During the source-monitoring test, half of the participants were asked about sources serially (one after the other) whereas the other half of the children were asked about sources in parallel (considering both sources simultaneously). Results demonstrated that working memory was a predictor of source-monitoring accuracy in both conditions, but inhibitory control was only related to source accuracy in the parallel condition. When age was controlled these relationships were no longer significant, suggesting that a more general cognitive development factor is a stronger predictor of source monitoring than executive function alone. Interestingly, the children aged 4–6 years made more accurate source decisions in the parallel condition than in the serial condition. The older children (aged 7–8) were overall more accurate than the younger children, and their accuracy did not differ as a function of interview condition. Suggestions are provided to guide further research in this area that will clarify the diverse results of previous studies examining whether executive function is a cognitive prerequisite for effective source monitoring

Challenges Facing East Asian Immigrant Children in Sexual Abuse Cases

Immigrants from East Asia make up 14.21% of the total number of immigrants in Canada. These families face many challenges as they acculturate to North America but, sadly, some of these children may be at risk for sexual abuse. In this position paper, we outline the ways in which East Asian children are at a particular disadvantage when considering prosecution of those who perpetrate abuse compared to Western non-immigrant children. We focus specifically on two areas of concern: 1) Cultural differences that can impact the disclosure of sexual abuse; and, 2) Language differences which reduce the chances that perpetrators will be prosecuted for sexual abuse. The consequences for East Asian immigrant youth who allege (or are suspected) that they are victims of abuse are serious. East Asian children face an uphill battle to see justice in sexual abuse cases. Thus, a significant portion of immigrant children will not see their abusers punished and, worse, the knowledge that prosecution is unlikely makes East Asian immigrant children a targeted population for those who abuse

Can paraphrasing increase the amount and accuracy of reports from child eyewitnesses?

Young children’s descriptions of sexual abuse are often sparse thus creating the need for techniques that elicit lengthier accounts. ‘Paraphrasing’, or repeating information children have just disclosed, is a technique sometimes used by forensic interviewers to clarify or elicit information. (e.g., if a child stated “He touched me”, an interviewer could respond “He touched you?”). However, the effects of paraphrasing have yet to be scientifically assessed. The impact of different paraphrasing styles on young children’s reports was investigated. Overall, paraphrasing per se did not improve the length, richness, or accuracy of reports when compared to open-ended prompts such as “tell me more,” but some styles of paraphrasing were more beneficial than others. The results provide clear recommendations for investigative interviewers about how to use paraphrasing appropriately, and which practices can compromise the quality of children’s reports

Children’s Use of a ‘Time Line’ to Indicate When Events Occurred

Children who allege abuse are often asked to provide temporal information such as when the events occurred. Yet, young children often have difficulty recalling temporal information due to their limited knowledge of temporal patterns and linguistic capabilities. As time is an abstract concept (we cannot see it), some investigators have begun to use ‘time-lines’ or pictorial representations of time to aid children. Yet, there is no published research testing whether children are able to use time-lines and whether they can provide adequate temporal information using them. We tested whether children could indicate the time-of-day of events using a pictorial time-line and then compared their responses to their parents’. Seven- to 8-year-olds were most consistent with parental estimates while 4-year-olds were least consistent. Responses from the 5- to 6-year-olds depended on the temporal task. Guessing and using general knowledge to estimate the time-of-day were ruled out, and so children were genuinely drawing on episodic memory when making time-line judgments. Thus, there was a developmental progression in children’s use of physical representations to communicate abstract information. These results are promising for the use of the time-line in forensic settings but much more research is needed

Subjective and Non-subjective Information in Children’s Allegations of Abuse

In this study, we were interested in how interviewers elicit subjective information in investigations of child abuse (e.g., descriptions of thoughts, emotions, opinions). Sixty-one interviews of children aged 4-12 years old were analyzed to determine the amount of subjective information versus non-subjective event details reported, and the type of question that elicited the information. Interviewers elicited more non-subjective than subjective information, although there was more focus on subjective information in the rapport-building phase than in the substantive phase when the allegations were elicited. Interviewer prompts and child responsiveness was congruent such that non-subjective questions elicited more non-subjective information, and subjective interviewer questions elicited more subjective information. The presence of subjective information in children’s testimony can influence children’s credibility, and the results of this study demonstrate that forensic interviewers play a significant part in the level of subjective information children provide

Binding an event to its source at encoding improves children\u27s source monitoring

Children learn information from a variety of sources and often remember the content but forget the source. While the majority of research has focused on retrieval mechanisms for such difficulties, the present investigation examines whether the way in which sources are encoded influences future source monitoring. In Study 1, 86 children aged 3 to 8 years participated in two photography sessions on different days. Children were randomly assigned to either the Difference condition (they were asked to pay attention to differences between the two events), the Memory control condition (asked to pay attention with no reference to differences), or the No-Instruction control (no special instructions were given). One week later, during a structured interview about the photography session, the 3-4 year-olds in the No-Instruction condition were less accurate and responded more often with \u27don\u27t know\u27 than the 7-8 year-olds. However, the older children in the Difference condition made more source confusions than the younger children suggesting improved memory for content but not source. In Study 2, the Difference condition was replaced by a Difference-Tag condition where details were pointed out along with their source (i.e., tagging source to content). Ninety-four children aged 3 to 8 years participated. Children in the Difference-Tag condition made fewer source-monitoring errors than children in the Control condition. The results of these two studies together suggest that binding processes at encoding can lead to better source discrimination of experienced events at retrieval and may underlie the rapid development of source monitoring in this age range

Children\u27s cognitive processing of abuse as described in investigative interviews.

A great deal of research has examined ways in which investigative interviewers can elicit accurate information from children. More recently, research has studied children’s own thoughts or comprehension of abuse, and how these types of statements relate to disclosure, others’ perceptions of child witnesses, and psychological trauma. However, little research has investigated multiple types of children’s thoughts about abuse as they occur in an actual investigative interview. The current study examined seven types of statements children made about their abuse in a sample of 86 transcripts of investigative interviews conducted by Child Protective Services and a police department in a mid-sized Ontario city. Children interviewed ranged from 4- to 17-years-of-age, with approximately equal numbers of males and females. Type of abuse disclosed in the interviews ranged from verbal abuse to sexual abuse. Two coders independently coded each transcript for seven statement types: expected consequences of disclosure, actual consequences of disclosure, minimization, justification for either self, perpetrator, or other, and blame. Whether the statements were elicited by an interviewer prompt or mentioned spontaneously by the child was also coded. Results demonstrated that children blamed the perpetrator more than any other statement type, consistent with previous research. Analyses also revealed a significant relationship between abuse type and children’s statements, and alleged perpetrator and children’s statements. Results from the current study have implications for disclosure, treatment of psychological trauma, and how parents, social workers, police officers, attorneys, and judges view children’s statements

Observations from Canadian practitioners about the investigation and prosecution of crimes involving child and adult witnesses

Hundreds of scientific studies on the competencies and limitations of eyewitnesses have been published, but few have sought input from front-line forensic interviewers. In the current study, a research agenda was established with in-depth input from 13 forensic interviewers. Interviewers indicated which techniques they use most often, rated the usefulness of various interview techniques, and disclosed common challenges when interviewing. Although many recommended techniques were used (e.g., the Cognitive Interview and Rapport Building), some techniques shown to be effective in eliciting quality testimony in scientific studies were not always used or considered useful by front-line interviewers (e.g., permission to correct the interviewer, permission to say ‘I don’t know’). Key areas were identified to guide future research (e.g., techniques when interviewing very young children, witnesses with developmental delays)

The effects of an intensive training and feedback program on investigative interviews of children

In the present study, we assessed the effectiveness of an extensive training and feedback program with investigative interviewers of child victims of alleged abuse and neglect in a large Canadian city. Twelve investigative interviewers participated in a joint training initiative that lasted eight months and involved classroom components and extensive weekly verbal and written feedback. Interviewers were significantly more likely to use open-ended prompts and elicited more information from children with open-ended prompts following training. These differences were especially prominent following a subsequent ‘refresher’ training session. No negative effects of training were observed. Clear evidence was found of the benefits of an intensive training and feedback program across a wide variety of investigative interviews with children. Although previous research has found benefits of training with interviewers of child sexual assault victims, the current study extends these findings to a wide range of allegations and maltreatment contexts

Reality-monitoring characteristics in confirmed and doubtful allegations of abuse

According to reality-monitoring theory, memories of experienced and imagined events are qualitatively different, and can be distinguished by children from the age of 3. Across three studies, a total of 119 allegations of sexual abuse by younger (aged 3-8) and older (aged 9-16) children were analyzed for developmental differences in the presence of reality-monitoring criteria, which should characterise descriptions of experienced events. Statements were deemed likely or unlikely to be descriptions of actual incidents using independent case information (e.g., medical evidence). Accounts by older children consistently contained more reality-monitoring criteria than those provided by younger children, and age differences were particularly strong when the cases were deemed doubtful (Studies 1 and 2)
