Abstract
Child eyewitnesses show a high false identification rate on target-absent (TA) lineups despite good performance on target-present (TP) lineups. One explanation is that children feel a social pressure to choose when presented with a TA lineup. We investigated whether experimenter familiarity would reduce social pressure and improve accuracy on TA lineups. Children (5-7 years, N = 120) watched a short video of a staged theft; 1-2 days later they completed a TP or TA lineup with a familiar or unfamiliar experimenter. Experimenter familiarity had an impact on lineup response in TA lineups only, with more correct 'not there' and fewer 'not sure' responses when the children were familiar with the experimenter. The results provide further evidence to support the social aspect of eyewitness identification decisions in children and provide a possible strategy to improve identification accuracy for those working with children in the criminal justice system.

Abstract
Parents' attachment orientations predict children's memory about distressing life events, such that parents who are less secure in close relationships tend to have children who are less accurate in their memory reports. This study examined whether socially supportive interviewing would reduce differences in children's memory performance associated with parents' attachment. Children (3 to 5 years, N = 63) and their primary caretakers took part in the Preschool Attachment Classification System (PACS), a moderately distressing event for children of preschool age that is based on the Strange Situation Procedure. Children's memory for the event was then tested shortly thereafter by either a supportive or a non-supportive interviewer. In the non-supportive condition, children whose parents scored higher on attachment avoidance provided lower proportions of correct free recall. However, the association was not significant for children in the supportive condition. In addition, higher parental attachment anxiety predicted lower proportions of correct free recall for children of highly avoidant parents, but not for children of parents lower in attachment avoidance. For direct questions, age differences in proportion correct and proportion incorrect favoured older children. Findings provide insight into interviewing techniques at time of memory retrieval that benefit children of insecure parents.

Abstract
In recent years, increasing efforts have been focused on testing strategies of improving victimized children's narrative productivity, given that, for many youth, finding out what has happened to them is crucial to intervening and promoting their well-being. Implicit encouragement strategies, such as back channeling by conversational partners, have shown some preliminary promise, but their precise effects on productivity and accuracy have not been adequately examined. In this study, 98 youth, ages 8-14, completed a laboratory-based stressful activity, and a week later, a surprise memory test regarding what happened in the lab activity. Interviewers varied their use of implicit encouragement. Open-ended recall questions asked youth about both factual details and detail about their feelings and thoughts during the laboratory activity. Implicit encouragement increased the amount of both types of details and had no effect on errors. In fact, few youth provided any incorrect information in their recall reports. Neither age nor stress was related to youth's productivity or accuracy, directly or in conjunction with implicit encouragement. Results highlight the value of interviewers using encouraging behaviors when questioning children and adolescents to elicit a range of information about prior stressful experiences.

Abstract
An alarming number of youth worldwide are victims of commercial sexual exploitation, particularly sex trafficking. Normative developmental processes and motivations across the adolescent period-the age when youth are at greatest risk for trafficking-combined with their history, make them highly likely to be reluctant to disclose their exploitation to police, who often encounter victims because they are suspected of delinquency and crime and who interrogate the victims as suspects. Little scientific and policy attention has been devoted to understanding how to question these victims in a way that reduces their disclosure reluctance and increases their provision of legally relevant information. In the current review, we describe research concerning trafficking victims' histories and exploitative experiences, juvenile suspects' and victims' encounters with the legal system, and best-practice forensic interviewing approaches to elicit disclosures from child victims. We highlight the implications of these areas for understanding the dynamics between how police encounter and interact with adolescent trafficking victims and whether and how the victims disclose trafficking details during these interactions. We close with an agenda for research to test interviewing methods for suspected victims of sex trafficking and with policy and practice recommendations for interviewers.

Abstract
Twenty-seven autistic children and 32 typically developing (TD) peers were questioned about an experienced event after a two-week delay and again after a two-month delay, using the Revised National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol. Recall prompts elicited more detailed and more accurate responses from children than recognition prompts. Autistic children recalled fewer correct narrative details than TD peers when questioned using open invitations, cued invitations, and directive questions. Nonetheless, they were as accurate as TD peers when responding to all types of prompts. The informativeness and accuracy of children's reports remained unchanged over time. Social support was beneficial when children were interviewed for the first time but not after a longer delay.

Abstract
In contrast to a large body of work concerning the effects of physiological stress reactivity on children's socioemotional functioning, far less attention has been devoted to understanding the effects of such reactivity on cognitive, including mnemonic, functioning. How well children learn and remember information under stress has implications for a range of educational, clinical, and legal outcomes. We evaluated 8-14 year olds' (N = 94, 50 female) memory for negative, neutral, and positive images. Youth had seen the images a week previously as a part of a laboratory stress task. At encoding and retrieval, and in between, youth provided saliva samples that were later assayed for cortisol, salivary α amylase (sAA), testosterone, and dehydroepiandrosterone (DHEA). Overall, higher cortisol reactivity to the lab task predicted enhanced memory for emotional but not neutral images. However, cortisol further interacted with pubertal hormones (testosterone and DHEA) to predict memory. Among girls with lower pubertal hormone levels, greater cortisol reactivity was associated with enhanced memory for negative information, whereas among boys with higher pubertal hormone levels, cortisol reactivity was associated with enhanced memory for positive information. sAA, was unrelated to memory. Overall, our findings reveal that individual differences in hormone levels associated with pubertal development have implications for our understanding of how stress-responsive biological systems directly and interactively influence cognitive outcomes.

Abstract
This study examines how children's age, gender and interviewer gender affected children's testimony after witnessing a theft. Children (N = 127, age = 6-11 years) witnessed an experimenter (E1) find money, which he/she may/may not have taken. E1 then asked the children to falsely deny that the theft occurred, falsely accuse E1 of taking the money, or tell the truth when interviewed by a second experimenter. Falsely denying or falsely accusing influenced children's forthcomingness and quality of their testimony. When accusing, boys were significantly more willing than girls to disclose about the theft earlier and without being asked directly. When truthfully accusing, children gave lengthier testimony to same-gendered adults. When denying, children were significantly more willing to disclose the theft earlier to male interviewers than to females. As children aged, they were significantly less likely to lie, more likely to disclose earlier when accusing, and give lengthier and more consistent testimony.

Abstract
Performance at identification lineup was assessed in eighty‐five 6‐ to 11‐year‐old typically developing children. Children viewed a live staged event involving 2 male actors, and were asked to identify the perpetrators from 2 separate lineups (one perpetrator‐present lineup and one perpetrator‐absent lineup). Half the children took part in lineups adapted by a registered intermediary (an impartial, trained professional who facilitates understanding and communication between vulnerable witnesses and members of the justice system), and half took part in “best‐practice” lineups, according to the current guidance for eyewitness identification in England and Wales. Children receiving assistance from a registered intermediary (relative to children who received best‐practice lineups) were more accurate in their identifications for perpetrator‐present lineups, and there was some evidence that they were also more accurate for perpetrator‐absent lineups. This provides the first empirical evidence for the effectiveness of registered intermediary support during identification lineups.

Abstract
Despite evidence that parents' attachment is associated with children's memory, less is known about the mechanisms underlying this association or the contexts in which the association is most meaningful. The present study examined whether parents' attachment predicted children's memory for stories about attachment-related topics, whether the cohesiveness of children's stories mediated the association between attachment and memory, and whether the association varied by interview support at retrieval. Five- to 6-year-olds completed attachment-relevant stories while parents provided information about their romantic attachment. Children's stories were coded for cohesiveness. A week later, children's memory for their stories was tested by either a supportive or non-supportive interviewer. When the interview was non-supportive, greater parental avoidance was associated with poorer memory, whereas when the interview was supportive, greater parental avoidance was associated with fewer errors. Findings provide insight into the context under which parents' attachment is most influential in shaping children's memory.

Abstract
Beginning in the 1980s, children have increasingly served as witnesses in the criminal, civil, and family courts; currently, >100 000 children appear in court each year. This statement updates the 1992 American Academy of Pediatrics (AAP) policy statement "The Child as a Witness" and the subsequent 1999 "The Child in Court: A Subject Review." It also builds on existing AAP policy on adverse life events affecting children and resources developed to understand and address childhood trauma. The purpose of this policy statement is to provide background information on some of the legal issues involving children testifying in court, including the accuracy and psychological impact of child testimony; to provide suggestions for how pediatricians can support patients who will testify in court; and to make recommendations for policy improvements to minimize the adverse psychological consequences for child witnesses. These recommendations are, for the most part, based on studies on the psychological and physiologic consequences of children witnessing and experiencing violence, as well as appearing in court, that have emerged since the previous AAP publications on the subject. The goal is to reduce the secondary traumatization of and long-term consequences for children providing testimony about violence they have experienced or witnessed. This statement primarily addresses children appearing in court as victims of physical or sexual abuse or as witnesses of violent acts; most of the scientific literature addresses these specific situations. It may apply, in certain situations, to children required to provide testimony in custody disputes, child welfare proceedings, or immigration court. It does not address children appearing in court as offenders or as part of juvenile justice proceedings.

Abstract
In the eyewitness identification literature, stress and arousal at the time of encoding are considered to adversely influence identification performance. This assumption is in contrast with findings from the neurobiology field of learning and memory, showing that stress and stress hormones are critically involved in forming enduring memories. This discrepancy may be related to methodological differences between the two fields of research, such as the tendency for immediate testing or the use of very short (1-2 hours) retention intervals in eyewitness research, while neurobiology studies insert at least 24 hours. Other differences refer to the extent to which stress-responsive systems (i.e., the hypothalamic-pituitary-adrenal axis) are stimulated effectively under laboratory conditions. The aim of the current study was to conduct an experiment that accounts for the contemporary state of knowledge in both fields. In all, 123 participants witnessed a live staged theft while being exposed to a laboratory stressor that reliably elicits autonomic and glucocorticoid stress responses or while performing a control task. Salivary cortisol levels were measured to control for the effectiveness of the stress induction. One week later, participants attempted to identify the thief from target-present and target-absent line-ups. According to regression and receiver operating characteristic analyses, stress did not have robust detrimental effects on identification performance.

Abstract
Despite considerable interest in understanding how stress influences memory accuracy and errors, particularly in children, methodological limitations have made it difficult to examine the effects of stress independent of the effects of the emotional valence of to-be-remembered information in developmental populations. In this study, we manipulated stress levels in 7-8- and 12-14-year-olds and then exposed them to negative, neutral, and positive word lists. Shortly afterward, we tested their recognition memory for the words and false memory for non-presented but related words. Adolescents in the high-stress condition were more accurate than those in the low-stress condition, while children's accuracy did not differ across stress conditions. Also, among adolescents, accuracy and errors were higher for the negative than positive words, while in children, word valence was unrelated to accuracy. Finally, increases in children's and adolescents' cortisol responses, especially in the high-stress condition, were related to greater accuracy but not false memories and only for positive emotional words. Findings suggest that stress at encoding, as well as the emotional content of to-be-remembered information, may influence memory in different ways across development, highlighting the need for greater complexity in existing models of true and false memory formation.

Abstract
Reliable laboratory protocols manipulating the intensity of biobehavioral arousal for children are uncommon, and those available have minimal converging evidence of their efficacy in manipulating arousal across multiple biological systems. This report presents two studies of the efficacy of the modified Trier Social Stress Test (TSST-M). In Study 1, sixty-three 7-15-year olds, and 19 young adults (18-25 yrs) completed the TSST-M. Comparable reactivity across age groups was observed for salivary cortisol, salivary alpha-amylase (sAA), pre-ejection period (PEP) and respiratory sinus arrhythmia (RSA), whereas self-reported stress was higher in adults compared to children. In Study 2, eighty-four 7-8-year olds and eighty-six 12-15-year olds were randomly assigned to a standard or low-stress TSST-M condition. Cortisol and self-reported stress responses were higher in the standard compared to the low-stress condition. In contrast, sAA and PEP were higher in the low-stress condition and RSA responses were comparable between the two TSST-M conditions. In addition, age group differences emerged in Study 2, though never in conjunction with the TSST-M manipulation. To test, refine, and advance theory about the implications of stress for child development, laboratory tasks that manipulate and enable assessment of biobehavioral arousal in children are needed.

Abstract
Laboratory social stress tests involving public speaking challenges are widely used for eliciting an acute stress response in older children, adolescents, and adults. Recently, a group protocol for a social stress test (the Trier Social Stress Test for Groups, TSST-G) was shown to be effective in adults and is dramatically less time-consuming and resource-intensive compared to the single-subject version of the task. The present study sought to test the feasibility and effectiveness of an adapted group public speaking task conducted with a racially diverse, urban sample of U.S. adolescents (N=191; 52.4% female) between the ages of 11 and 18 (M=14.4 years, SD=1.93). Analyses revealed that this Group Public Speaking Task for Adolescents (GPST-A) provoked a significant increase in cortisol production (on average, approximately 60% above baseline) and in self-reported negative affect, while at the same time avoiding excessive stress responses that would raise ethical concerns or provoke substantial participant attrition. Approximately 63.4% of participants exhibited an increase in cortisol levels in response to the task, with 59.2% of the total sample showing a 10% or greater increase from baseline. Results also suggested that groups of five adolescents might be ideal for achieving more uniform cortisol responses across various serial positions for speech delivery. Basal cortisol levels increased with age and participants belonging to U.S. national minorities tended to have either lower basal cortisol or diminished cortisol reactivity compared to non-Hispanic Whites. This protocol facilitates the recruitment of larger sample sizes compared to prior research and may show great utility in answering new questions about adolescent stress reactivity and development.

Abstract
Research concerning the relations between stress and children's memory has been primarily correlational and focused on memory volume and accuracy. In the current study, we experimentally manipulated 7- and 8-year-olds' and 12- to 14-year-olds' experienced stress during a to-be-remembered event to examine the effects of stress on the content of their memory. We further manipulated the degree of interviewer support at retrieval to determine whether it moderated the effects of stress at encoding on memory. Children's age, gender, stress at encoding, and interviewer support all influenced the type of information included in their narrative reports. Most notably, across ages, children who experienced a more stressful event but were questioned in a supportive manner provided the largest ratio of terms representing internal states such as those about cognitions and emotions. Results suggest that how children process past events may be influenced by both the nature of the event itself and the context within which it is recalled.
