Abstract

OBJECTIVE

The current study examined children's eyewitness memory nearly 4 years after an event and the ability of adults to evaluate such memory.

METHOD

In Phase 1, 7- and 10-year olds were interviewed about a past event after a nearly 4-year delay. The interview included leading questions relevant to child abuse as well as statements designed to implicate the original confederate. In Phase 2, laypersons and professionals watched a videotaped interview (from Phase 1) that they were misled to believe was from an ongoing abuse investigation. Respondents then rated the child's accuracy and credibility, and the probability that the child had been abused.

RESULTS

In Phase 1, few significant age differences in memory accuracy were found, perhaps owing in part to small sample size. Although children made a variety of commission errors, none claimed outright to have been abused. Nevertheless, some of the children's answers (e.g., saying that their picture had been taken, or that they had been in a bathtub) might cause concern in a forensic setting. In Phase 2, professional and nonprofessional respondents were unable to reliably estimate the overall accuracy of children's statements. However, respondents were able to reasonably estimate the accuracy of children's answers to abuse questions. Respondents were also more likely to think that 7-year olds compared to 10-year olds had been abused. Professionals were significantly less likely than nonprofessionals to believe that credible evidence of abuse existed. Professionals who indicated personal experience with child abuse or a close relationship with an abuse victim were more likely to rate children as abused. A gender bias to rate boys as more accurate than girls was apparent among laypersons but not professionals.

CONCLUSIONS

Children were generally resistant to suggestions that abuse occurred during a long-ago generally forgotten event, but some potentially concerning errors were made. Both professionals and non-professionals had difficulty estimating the accuracy of children's reports, but adults were more likely to rate children as accurate if the children answered abuse-related questions correctly. Training and personal experience were associated with adults' ratings of children's reports. Implications for evaluations of child abuse reports are discussed.

摘要

目的

本研究考察了事件发生近4年后儿童的目击证人记忆,以及成年人评估此类记忆的能力。

方法

在第一阶段,对7岁和10岁的儿童进行了访谈,访谈内容是关于一件近4年前发生的往事。访谈包括与虐待儿童相关的引导性问题,以及旨在牵连最初同谋的陈述。在第二阶段,外行人与专业人士观看了一段录像采访(来自第一阶段),他们被误导认为这是正在进行的虐待调查的采访。受访者随后对儿童的准确性和可信度,以及儿童曾遭受虐待的可能性进行评分。

结果

在第一阶段,未发现记忆准确性方面存在显著的年龄差异,这可能部分归因于样本量较小。尽管儿童出现了各种错误,但没有人直接声称曾遭受虐待。然而,一些儿童的回答(例如,说他们的照片被拍了,或者他们曾在浴缸里)在法医环境中可能会引起关注。在第二阶段,专业和非专业受访者都无法可靠地估计儿童陈述的总体准确性。然而,受访者能够合理估计儿童对虐待问题回答的准确性。受访者也更倾向于认为7岁儿童比10岁儿童曾遭受虐待。专业人士认为存在虐待可信证据的可能性明显低于非专业人士。表示有虐待儿童个人经历或与虐待受害者有密切关系的专业人士更有可能将儿童评为曾遭受虐待。在外行人中存在将男孩评为比女孩更准确的性别偏见,但在专业人士中则不存在。

结论

儿童通常对暗示在一个早已被遗忘的事件中发生虐待具有抵抗力,但仍出现了一些可能令人担忧的错误。专业人士和非专业人士在估计儿童报告的准确性方面都有困难,但如果儿童正确回答了与虐待相关的问题,成年人更有可能认为儿童的回答是准确的。培训和个人经历与成年人对儿童报告的评分有关。讨论了对虐待儿童报告评估的影响。
