Does a Warning Help Children to More Accurately Remember an Event, to Resist Misleading Questions, and to Identify Unanswerable Questions?

Investigative Interviewing of Aboriginal Children in Cases of Suspected Sexual Abuse

This study examined the investigative interviewing of Australian Aboriginal children in cases of alleged sexual abuse, with a focus on three commonly included components of interview protocols: ground rules, practice narrative, and substantive phase. Analysis of 70 field transcripts revealed that the overall delivery and practice of ground rules at the beginning of the interview was positively associated with the spontaneous usage of rules in children's narratives of abuse. When specifically examining the "don't know" rule, however, only practice had an effect of children's usage of the rule (as opposed to simple delivery or no delivery at all). Children spoke more words overall, and interviewers used more open-ended prompts during the substantive phase when the interviews contained a practice narrative. Children most often disclosed sexual abuse in response to an open-ended prompt; however, they produced the most words in response to suggestive prompts. This article concludes with a discussion of the effectiveness of ground rules, practice narratives, and questioning with Aboriginal children.

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.

Developmental Progression in Children’s Strategic Memory Regulation

A developmental study was conducted that investigated 7- to 11- years-olds’ ability to strategically regulate their memory performance. The study, based on Koriat and Goldsmith’s (1996) theoretical framework, sought to stimulate strategic regulation processes. In order to do so, the threshold to provide or withhold answers was manipulated and included bonuses for correct responding and penalties for incorrect answers. Participants were shown a video concerning the production of sugar from beets and were individually interviewed a week later. Responses had to be made to both answerable and unanswerable questions in both an open-ended and a yes/no question format. The results revealed that depending on the question format, there were different effects of the threshold manipulations on the frequencies of correct, incorrect, and “I don’t know” responses. Although there were no differences in response behaviour between the 1:0 and 1:1 incentives conditions when the questions were open-ended, children were able to differentially respond to the two bonus-to-penalty ratios when the questions were in yes/no format. Consistently, there were no interactions between age and response threshold indicating that strategic regulation competencies develop slowly but continuously during the primary school years showing the first signs of emerging competencies from an age of 7 onwards.

Age differences in the effects of social influence on children's eyewitness performance and their metacognitive monitoring

The current work investigated the effects of social influence on children's recall accuracy and metacognitive monitoring. Two studies were conducted in which 8- and 10-year-olds were confronted with postevent information in an interview situation. An interviewer (Study 1) or a confederate (Study 2) provided postevent information with two levels of assertiveness, inducing (a) a variation of conformity pressure and (b) a variation of information credibility. Afterwards, children's confidence judgments were assessed. The results revealed significant age differences in children's ability to adequately cope with variations of social influence. Although conformity pressure was especially important for the 8-year-olds, effects of informative social influence were independent of age. However, 10-year-olds were also able to act appropriately on low credibility, thereby demonstrating a more sophisticated consideration of social influence sources. Moreover, varying assertiveness also affected the quality of children's confidence judgments by improving their metacognitive differentiation skills.

The strategic regulation of children’s memory performance and suggestibility

We report two empirical studies that investigated previously reported benefits of a high accuracy motivation, and thus a high threshold, for children's and adults' event recall and for their ability to resist false suggestions. In the studies, 6-, 7-, and 8-year-olds, as well as adults, were shown a brief video about an event and were later asked unbiased and misleading questions about it. In Study 1, participants were either (a) given the typical accuracy instructions (including the option to answer with "I don't know"), (b) reminded of the accuracy instructions during the interview, or (c) immediately given feedback and a token for every correct answer. The results showed that the reminders were ineffective in stimulating strategic control behavior in children, independent of age. In Study 2, the confounding effects of feedback and incentives were disentangled by contrasting (a) free report, (b) feedback only, (c) incentives only, and (d) feedback plus incentives. Analyses on recall performance and suggestibility revealed that both feedback and incentives are necessary to increase children's accurate memory reports.
