Children from 5 to 12 years of age (N=779) were shown a videotape where a preschool teacher has money stolen from her wallet. Children were shown a lineup, and for children in the bystander condition, the lineup contained a familiar bystander without the thief. Children in the control condition viewed the same lineup but they had not seen the bystander in the videotape. Among the 11–12-year olds, participants in the bystander condition were significantly more likely than control participants to misidentify the familiar bystander. This effect was not found in children from 5 to 10 years of age. When children in the control condition were shown a lineup that contained the thief without the bystander, the 11–12-year olds were significantly more likely than the younger children to correctly identify the thief. These findings demonstrate that age can both increase and decrease the accuracy of children’s lineup identification accuracy depending on the task at hand and the content of a lineup. 相似文献

Fifteen autosomal STR loci were typed in a population sample of 318 unrelated individuals from northern Greece. Allele frequencies were determined, and Hardy-Weinberg equilibrium tested, for the following loci: D5S818, D7S820, TH01, TPOX, vWA, CSF1PO, D16S539, D13S317, D8S1179, D3S1358, FGA, PENTA D, PENTA E, D21S11, D18S51. 相似文献

The mitochondrial hypervariable regions I and II have proven to be a useful target for analysis of forensic materials, in which the amount of DNA is limited or highly degraded. Conventional mitochondrial DNA (mtDNA) sequencing can be time-consuming and expensive, limitations that can be minimized using a faster and less expensive typing assay. We have evaluated the exclusion capacity of the linear array mtDNA HVI/HVII region-sequence typing assay (Roche Applied Science) in 16 forensic cases comprising 90 samples. Using the HVI/HVII mtDNA linear array, 56% of the samples were excluded and thus less than half of the samples require further sequencing due to a match or inconclusive results. Of all the samples that were excluded by sequence analysis, 79% could be excluded using the HVI/HVII linear array alone. Using the HVI/HVII mtDNA linear array assay, we demonstrate the potential to decrease sequencing efforts substantially and thereby reduce the cost and the turn-around time in casework analysis. 相似文献

Forensic evaluations must systematically assess malingering and related response styles. In the criminal forensic domain, competency to stand trial evaluations are the most common referrals. Effective screens for feigned incompetency would be valuable assets for forensic evaluations. This study evaluates the effectiveness of the Miller Forensic Assessment of Symptoms Test (MFAST) as a screen for feigned incompetency. Using a simulation design, the MFAST was tested on jail and competency-restoration samples. Most notably, recommended MFAST cut score (6) was useful for the identification of feigning cases in competency evaluations. Recommendations for forensic practice, including the advantages and disadvantages of systematic screens, are discussed. 相似文献

During the past 20 years, researchers have documented the widespread problem of rape in American society. Approximately one in four women are raped in their adult lifetime, which causes severe psychological distress and long-term physical health problems. The impact of sexual assault extends far beyond rape survivors as their family, friends, and significant others are also negatively affected. Moreover, those who help rape victims, such as rape victim advocates, therapists, as well as sexual assault researchers, can experience vicarious trauma. Future research and advocacy should focus on improving the community response to rape and the prevention of sexual assault. 相似文献
