Sources of Unreliable Testimony from Children

We distilled research findings on sources of unreliable testimony from children into four principles that capture how the field of forensic developmental psychology conceptualizes this topic. The studies selected to illustrate these principles address three major questions: (a) how do young children perform in eyewitness studies, (b) why are some children less accurate than others, and (c) what phenomena generate unreliable testimony? Throughout our research, our focus is on factors other than lying that produce inaccurate or seemingly inconsistent autobiographical reports.Collectively, this research has shown that (a) children’s eyewitness accuracy is highly dependent on context, (b) neurological immaturity makes children vulnerable to errors under some circumstances, and (c) some children are more swayed by external influences than others. Finally, the diversity of factors that can influence the reliability of children’s testimony dictates that (d) analyzing children’s testimony as if they were adults (i.e., with adult abilities, sensibilities, and motivations) will lead to frequent misunderstandings. It takes considerable knowledge of development—including information about developmental psycholinguistics, memory development, and the gradual emergence of cognitive control—to work with child witnesses and to analyze cases as there are many sources of unreliable testimony

The use of ground rules in investigative interviews with children : a synthesis and call for research

Guidelines for conducting investigative interviews with children often include instructions that explain the conversational rules of the interview. Despite the widespread and international use of such instructions (also referred to as "ground rules"), the body of research characterizing children\u27s understanding of these rules and documenting the impact of instruction on memory reports is relatively small. We review the use of ground rules in investigative interviews, the developmental differences that likely underlie children\u27s ability to make sense of these rules, and research pertaining to the effects of the ground rules commonly included in interview guidelines on the reports of 3- to 13-year-old children. We then present a study space analysis concerning the five ground rules reviewed: (a) a statement about interviewer naïveté regarding the target events, (b) instructions to tell the interviewer when a mistake has been made, (c) cautions that some questions may be repeated, and instructions to say (d) "I don\u27t understand" and (e) "I don\u27t know." The results demonstrate obvious gaps in this body of literature, with only the "I don\u27t know" ground rule having received significant attention. In addition to exploring how individual rules impact interview performance, we encourage more process-oriented studies that relate developmental differences in ground rules benefits to the cognitive processes that underlie rule understanding and implementation. Optimally, this research should identify the most suitable format and placement of instruction in interviews and broaden to more often include field studies of child witnesses

Identification of six new susceptibility loci for invasive epithelial ovarian cancer.

Genome-wide association studies (GWAS) have identified 12 epithelial ovarian cancer (EOC) susceptibility alleles. The pattern of association at these loci is consistent in BRCA1 and BRCA2 mutation carriers who are at high risk of EOC. After imputation to 1000 Genomes Project data, we assessed associations of 11 million genetic variants with EOC risk from 15,437 cases unselected for family history and 30,845 controls and from 15,252 BRCA1 mutation carriers and 8,211 BRCA2 mutation carriers (3,096 with ovarian cancer), and we combined the results in a meta-analysis. This new study design yielded increased statistical power, leading to the discovery of six new EOC susceptibility loci. Variants at 1p36 (nearest gene, WNT4), 4q26 (SYNPO2), 9q34.2 (ABO) and 17q11.2 (ATAD5) were associated with EOC risk, and at 1p34.3 (RSPO1) and 6p22.1 (GPX6) variants were specifically associated with the serous EOC subtype, all with P < 5 × 10(-8). Incorporating these variants into risk assessment tools will improve clinical risk predictions for BRCA1 and BRCA2 mutation carriers.COGS project is funded through a European Commission's Seventh Framework Programme grant (agreement number 223175 ] HEALTH ]F2 ]2009 ]223175).

Functional mechanisms underlying pleiotropic risk alleles at the 19p13.1 breast-ovarian cancer susceptibility locus

A locus at 19p13 is associated with breast cancer (BC) and ovarian cancer (OC) risk. Here we analyse 438 SNPs in this region in 46,451 BC and 15,438 OC cases, 15,252 BRCA1 mutation carriers and 73,444 controls and identify 13 candidate causal SNPs associated with serous OC (P=9.2 × 10-20), ER-negative BC (P=1.1 × 10-13), BRCA1-associated BC (P=7.7 × 10-16) and triple negative BC (P-diff=2 × 10-5). Genotype-gene expression associations are identified for candidate target genes ANKLE1 (P=2 × 10-3) and ABHD8 (P<2 × 10-3). Chromosome conformation capture identifies interactions between four candidate SNPs and ABHD8, and luciferase assays indicate six risk alleles increased transactivation of the ADHD8 promoter. Targeted deletion of a region containing risk SNP rs56069439 in a putative enhancer induces ANKLE1 downregulation; and mRNA stability assays indicate functional effects for an ANKLE1 3′-UTR SNP. Altogether, these data suggest that multiple SNPs at 19p13 regulate ABHD8 and perhaps ANKLE1 expression, and indicate common mechanisms underlying breast and ovarian cancer risk

Sketching women in court: The visual construction of co-accused women in court drawings

This paper explores the visual construction and representation of co-accused women offenders in court drawings. It utilises three case studies of female co-defendants who appeared in the England and Wales court system between 2003 and 2013. In doing so this paper falls into three parts. The first part considers the emergence of the sub-discipline, visual criminology and examines what is known about the visual representation of female offenders. The second part presents the findings of an empirical investigation, which involved engaging in a critical, reflexive visual analysis of a selection of court drawings of three female co-offenders. The third part discusses the ways in which the court artists' interpretation, the conventions of court sketching, and motifs of female offenders as secondary actors, drew on existing myths and prejudices by representing the women as listening, remorseless ‘others’

Evidence Supporting Restrictions On Uses of Body Diagrams in Forensic Interviews

Objective: This study compared two methods for questioning children about suspected abuse: standard interviewing and body-diagram-focused (BDF) interviewing, a style of interviewing in which interviewers draw on a flip board and introduce the topic of touching with a body diagram. Methods: Children (N=261) 4-9 years of age individually participated in science demonstrations during which half the children were touched two times. Months later, parents read stories to their children that described accurate and inaccurate information about the demonstrations. The stories for untouched children also contained inaccurate descriptions of touching. The children completed standard or BDF interviews, followed by source-monitoring questions. Results: Interview format did not significantly influence (a) children\u27s performance during early interview phases, (b) the amount of contextual information children provided about the science experience, or (c) memory source monitoring. The BDF protocol had beneficial and detrimental effects on touch reports: More children in the BDF condition reported experienced touching, but at the expense of an increased number of suggested and spontaneous false reports. Conclusions: The two props that are characteristic of BDF interviewing have different effects on testimonial accuracy. Recording answers on a flip board during presubstantive phases does not influence the quality of information that children provide. Body diagrams, however, suggest answers to children and elicit a concerning number of false reports. Practice implications: Until research identifies procedures and/or case characteristics associated with accurate reports of touching during diagram-assisted questioning, interviewers should initiate discussions about touching with open-ended questions delivered without a body diagram

The Influence of Disclosure History and Body Diagrams On Children\u27s Reports of Inappropriate Touching: Evidence from a New Analog Paradigm

We tested a new paradigm for child eyewitness research that incorporates children\u27s disclosure histories into analog study designs. Mr. Science - Germ Detective creates meaningful touching experiences and varied patterns of preinterview disclosures by convincing children that touching in the laboratory is potentially contaminating (germy). Children (N = 287, 4 to 8 years) heard that Mr. Science could no longer touch children\u27s skin and then participated in an educational program involving 2 attempted touches. A week later, their disclosure histories were determined by a phone call that occurred a day before a forensic-style interview in the laboratory. This interview was delivered in 1 of 2 conditions: with early open-ended and more focused prompts delivered without a diagram (conventional-first condition) or with an initial diagram-assisted phase (diagram-first condition). Results confirmed that the new paradigm produces salient touches and performance patterns across open-ended and more focused questions that mirror well-known findings in eyewitness studies. A diagram made it easier for research assistants to elicit detailed reports of touching, but only among children 5 years and older who had not previously disclosed. Accuracy rates were comparable across interview conditions for early substantive phases but declined among older children when interviewers used diagrams to elicit additional reports late in interviews. These findings demonstrate that disclosure history is an important variable to include in analog study designs and confirm that Germ Detective is a promising paradigm for initial tests of new interviewing strategies.

Comfort Drawing During Investigative Interviews: Evidence of the Safety of a Popular Practice

Objective: This study evaluated the impact of comfort drawing (allowing children to draw during interviews) on the quality of children\u27s eyewitness reports. Methods: Children (N= 219, 5 to 12 years) who had participated in an earlier memory study returned 1 or 2 years later, experienced a new event, and described these events during phased, investigative-style interviews. Interviewers delivered the same prompts to children in the no drawing and drawing conditions but provided paper and markers in the drawing condition, invited these children to draw, and periodically asked if they would like to make another picture. Results: Most children in the drawing condition were interested in using the materials, and measures of eyewitness performance were sensitive to differences in cognitive ability (i.e., age) and task difficulty (i.e., delay between the remote event and interview). Comfort drawing had no overall impact as evidenced by nonsignificant main effects of condition across 20 performance measures, although more of the younger children reported experienced touching in the drawing than no drawing condition. Conclusions: The children successfully divided attention between voluntary drawing and conversations about past events. Importantly, comfort drawing did not impair the amount of information recalled, the accuracy of children\u27s answers, or even the extent to which interviewers needed to prompt for answers. Due to the large number of analyses, the benefit of drawing for younger, touched children requires replication. Practice Implications: Comfort drawing poses no documented risks for typically-developing school-aged children, but the practice remains untested for younger children and those with cognitive impairments
