This study investigated adults’ judgments of the honesty of children's coached true and fabricated mock testimony. Adults saw video clips of children testifying in a mock court about a true or fabricated event in their lives. They were asked to make an assessment of the truthfulness of the testimony, and respond to questions about their perception of children's credibility. Half of the adults saw children testifying after a competence examination, and the other half saw children testifying without a competence examination. Overall, girls were rated as more competent than boys, and their testimony was more likely to be believed. Younger children were more likely to be rated as incompetent than older children. A factor analysis of adults’ responses revealed six factors which significantly predicted adults’ overall assessment of children's credibility, and their evaluations of children's competence to testify. Adults’ detection accuracy was at chance, with the majority of children rated as truthful. Viewing the competency examination and cross-examination did not improve the adults’ detection accuracy. However, seeing the cross-examination made adults’ less likely to believe children's testimony. The implications of these results for the judicial system are discussed. 相似文献

Research examining children's temporal knowledge has tended to utilize brief temporal intervals and singular, neutral events, and is not readily generalizable to legal settings in which maltreated children are asked temporal questions about salient, repeated abuse that often occurred in the distant past. To understand how well maltreated children can describe temporal location and numerosity of documented, personal experiences, we assessed 167 6- to 10-year-old maltreated children's temporal memory for changes in their living arrangements and prior visits to court. Small percentages of children were capable of providing exact temporal location information (age, month, or season) regarding their first or last placement or court experience, or numerosities for placements or court visits. Greater knowledge of current temporal locations did not predict better performance. However, older children's performance for several temporal judgments was better than chance, and their reports were not largely discrepant from the truth. Findings suggest caution when questioning maltreated children about when and how many times prior events occurred. 相似文献

According to law enforcement, many witnesses are intoxicated either at the time of the crime, the interview, or both (Evans et al., Public Policy Law 15(3):194-221, 2009). However, no study to date has examined whether intoxicated witnesses' recall is different from sober witnesses' and whether they are more vulnerable to misinformation using an ecologically valid experimental design. Intoxicated, placebo, and sober witnesses observed a live, staged theft, overheard subsequent misinformation about the theft, and took part in an investigative interview. Participants generally believed they witnessed a real crime and experienced a real interview. Intoxicated witnesses were not different from placebo or sober witnesses in the number of accurate details, inaccurate details, or "don't know" answers reported. All the participants demonstrated a misinformation effect, but there were no differences between intoxication levels: Intoxicated participants were not more susceptible to misinformation than sober or placebo participants. Results are discussed in the light of their theoretical and applied relevance. 相似文献

Interest in the relationship between autism and violence has increased in recent years; however, no link has clearly been established between them. Researchers remain curious if autistic people with certain traits (e.g., a history of trauma) are at greater risk of violence than those individuals with autism alone. In this article, we detail two individuals with homicidal ideation (HI) admitted to inpatient psychiatric units who were found to have a diagnosis of autism without language impairment. These cases illustrate the need for mental health providers to consider autism in their differential diagnosis when evaluating an individual with HI. Broadly, we consider how an autistic individual could be susceptible to developing HI and explore treatments specific to autistic individuals that may be helpful in such cases. 相似文献

The validity and feasibility of using DNA collection cards in the field for preservation and analysis of Cannabis sativa genotypes were investigated using a highly specific hexanucleotide marker. Collection cards were submitted to the National Marijuana Initiative, which selectively trained and managed the collection of specific types of samples from a variety of participating agencies. Samples collected at seizure sites included fresh marijuana leaf samples, dried "dispensary" samples, U.S. border seizures, and hashish. Using a standardized PCR kit with custom-labeled oligonucleotide primers specific to marijuana, collection cards produced eight genotypes and 13 different alleles, extremely low baselines, and no cross-reactivity with control plant species. Results were produced from all sample types with the exception of hashish. Plant DNA collection cards represent an easily implementable method for the genetic identification and relatedness of C. sativa street and grow site-seized samples with applications for databasing and market disruption. 相似文献
