Witnesses' susceptibility to misleading post-event information delivered in a social media-style video

In many criminal cases, outcomes rely on eyewitness evidence. Exposure to misleading information after an event reduces the accuracy of witnesses' memories. In some circumstances, warnings about misinformation can protect witnesses. As social media is a growing source of misleading information, this study examined the effect of misleading post-event information delivered via a social media-style video, as well as the utility of a minimal versus detailed warning. Participants (N = 145) watched a video showing an electrician stealing items from a client's home. Next, they received one of three pre-warnings regarding forthcoming misleading information: a minimal warning indicating that caution should be taken, a detailed warning specifying the presence of misleading information, or no warning. Participants received the misleading information via a social media video or a standard text-based narrative. Finally, they completed a recognition test. Although delivery method did not affect errors for misleading items, detailed warnings were only effective against text-based misleading information. Participants were more confident about their correct than incorrect responses for misleading items; confidence was not affected by delivery method or warning. This experiment is the first to demonstrate people's susceptibility to misleading post-event information delivered in a social media-style video using an eyewitness paradigm.

Open-ended initial invitations are particularly helpful in eliciting forensically relevant information from child witnesses

BACKGROUND

Open-ended prompting is an essential tool for interviewers to elicit evidentiary information from children reporting abuse. To date, no research has examined whether different types of open-ended prompts elicit details with differing levels of forensic relevance.

OBJECTIVE

To examine interviewers' use of three open-ended prompt subtypes (initial invitations, breadth prompts, and depth prompts) and compare the forensic relevance of the information elicited by each.

PARTICIPANTS AND SETTING

Transcripts of field interviews conducted by 53 police interviewers with children aged 6- to 16-years alleging abuse were examined.

METHODS

In each transcript, initial invitations, breadth prompts, and depth prompts were identified, and the child's response was parsed into clauses. Clauses were classified according to their forensic relevance: essential to the charge (i.e., a key point of proof or element of the offence), relevant to the offending (i.e., what occurred before, during, or after an incident but not an essential detail), context (i.e., background information), irrelevant to the charge, no information provided, or repeated information already provided earlier.

RESULTS

Interviewers posed fewer initial invitations than breadth and depth prompts, p < .001, ηp2 = 0.58. Initial invitations elicited higher proportions of essential and relevant clauses than breadth and depth prompts; depth prompts further elicited higher proportions of essential clauses than breadth prompts, ps ≤ 0.001. We found few effects of children's age.

CONCLUSIONS

Initial invitations are a particularly useful subtype of open-ended prompt for interviewers to elicit details that are legislatively essential for prosecution of crimes from children of all ages.

The effects of episode spacing on adult's reports of a repeated event

Witnesses' reports of repeated events have been the focus of much research; however, the spacing interval between each episode of the event has differed greatly. The aim of the current study was to determine whether spacing interval affects participants' memory reports. Adults (N = 217) watched one (n = 52) or four videos depicting workplace bullying. The repeated event participants watched the four videos all in one day (n = 55), one per day over four consecutive days (n = 60), or one every three days over 12 days (n = 50). One week after the last (or only) video, participants reported on that video and answered some reflective questions about the procedure. Repeated-event participants also reported on what usually happens across the videos. Single-event participants reported proportionally more accurate information about the target video than repeated-event participants, and spacing interval did not affect repeated event participants' accuracy. However, accuracy scores were close to ceiling while errors rates were at floor levels, preventing us from drawing strong conclusions. We found some evidence that episode spacing affected participants' perceptions of their memory performance. Overall, spacing may have a minimal effect on adults' memory for repeated events, but further research is required.

Laypeople's perceptions of the effects of event repetition, reporting delay, and emotion on children's and adults' memory

For crimes such as child abuse and family violence, jurors' assessments of memory reports from key witnesses are vital to case outcomes in court. Since jurors are not experts on memory, the present research measured laypeople's (i.e., non-experts') beliefs about how three key factors affect witnesses' memory reports for an experienced event: how frequently an event was experienced (repeated, single), the delay between experiencing and reporting the event, and the emotional valence of the event. Across two studies, lay participants completed an online survey that measured their beliefs about each factor. In Study 1, 51 participants completed a survey about how the three factors affect children's memory. In Study 2, another 51 participants completed a survey about how the three factors affect adult's memory. Across both studies, delays were believed to worsen memory, and emotion was believed to improve memory. Beliefs about single and repeated events showed different patterns across the studies. In Study 1, participants' beliefs about children's memory for repeated experience were variable. In Study 2, participants believed that adults' memory was worse for repeated events than single events. Overall, laypeople demonstrated many accurate beliefs about memory, but showed some confusion about children's memory for repeated events.

Situational Characteristics Uniquely Associated With Children's Exposure to Intimate Partner Violence

Exposure to parental violence can have devastating consequences for children, including significant personal, social, and academic problems. The present study determined the situational factors that are associated with children's exposure to intimate partner violence (IPV) incidents. To examine whether these factors were unique to child witnesses' presence at IPV incidents, we also determined the factors that are associated with children's exposure to family violence (FV) and other family member witnesses' exposure to IPV incidents. Participants responded to an online panel survey investigating the role of alcohol and other drugs in family and domestic violence incidents in Australia. Nine hundred fifty-two respondents reported an IPV incident and 299 reported an FV incident; they provided details about their most recent incident. Results showed that child witnesses were more likely to be present during IPV incidents if the incident took place at home (odds ratio [OR] = 3.10), if a similar incident had occurred previously (OR = 1.66), if drugs were involved (OR = 1.60), and if a police report was made (OR = 2.61). There was some overlap with the other witness and violence combinations: The presence of a police report also predicted child witnesses' presence at FV incidents, and a home location also predicted other family member witnesses' presence at IPV incidents. These results enhance our understanding of the situations in which children might witness IPV incidents; future research is needed to determine whether these situational factors can be used to judge risk.

Factors influencing the perceived credibility of children alleging physical abuse

Adults' assessments of the credibility of children's reports are affected by factors including the frequency of abuse, reporting delays and the child's age. The present study examined whether similar factors affect the perceived credibility of children reporting physical abuse, which is more common than sexual abuse. Two hundred and eight mock jurors read a simulated transcript of a child reporting physical abuse to police and made credibility ratings. Within each transcript, abuse frequency (once, repeated), reporting timing (recent, delayed), police question type (open, closed) and child age (6 or 10 years) were manipulated. The child was considered more credible when the abuse was only experienced once and reported shortly after it occurred, and when prompted with open questions. The child's age did not affect credibility judgments. Current findings support recommendations to prioritise open questions with children and provide evidence for extension of the benefits of open questions to children's credibility.

Challenges in translating interview protocols for alleged child victims of sexual abuse to different languages: A case study

Adequate interviewing of alleged victims of child sexual abuse is critical for the investigation and for preserving the welfare of the child. Investigative interview protocols for children (IIPCs) have been developed to meet this twofold purpose. This article focuses on one previously unexplored issue related to applicability of IIPCs: how well they translate into other languages. This case study provides an in-depth analysis of an example of the translation of an IIPC to a new language and its adaptation to a particular cultural setting. Using an interpretive description approach and a mixed-method, stages and outputs of the adaptation process are described, as well as the amount, type and nature of difficulties in translation that were identified and corrected across the process. The main threats to translation equivalence arose from differences among languages, but also from cultural and contextual differences. Prompts to children and interviewers within the protocol presented different translation challenges. Consultation with experts and the protocol's advisors, along with team discussions, were beneficial in identifying and solving translation issues. Typical translation issues and practical recommendations on how to translate and culturally adapt IIPCs effectively are discussed.

The effects of episode similarity on children's reports of a repeated event

Much research has tested techniques to improve children's reporting of episodes from a repeated event by interviewing children after they have experienced multiple episodes of a scripted event. However, these studies have not considered any effects of the similarity shared between event episodes on children's reports. In the current study, 5- to 9-year-olds experienced four episodes of a scripted repeated event that shared a high (n = 76) or low (n = 76) degree of similarity, and were subsequently interviewed about individual episodes. The proportional amount and accuracy of children's reported details were tallied. Children reported proportionally more details and more script deviations after experiencing the high, compared to low, similarity event. Conversely, children were more accurate in their episodic reports when they experienced the low, compared to high, similarity event. The current findings have implications for the generalisability and comparability of past results across laboratory studies.

Other misconduct evidence in appeals against conviction in child sexual abuse trials

Child sexual abuse (CSA) trials may feature evidence relating to behaviours beyond the charges laid. This 'other misconduct' evidence can add context to the offending and may relate to more than one complaint or victim, indicating a pattern of thinking and behaviour, or that multiple incidents are unlikely to be coincidental. Directions to the jury regarding such evidence are complex and error prone, giving grounds for appeal. This study investigates successful appeals against conviction based on other misconduct evidence by analysing child and adult sexual assault cases listed in the Supreme Court of Appeal (Victoria) between 2004 and 2014. The appeals were equally successful in child and adult cases and equally likely to result in retrial. Specific errors in directions were identified and explanations are presented. Jury directions continue to be a source of error in sexual assault trials and can result in further attrition from the criminal justice system.

Characteristics of Successful and Unsuccessful Appeals Against Conviction for Child Sexual Abuse

The current study investigated (a) the effect of legislative reforms and amendments to judges' directions to juries in the success of appeals against conviction for child sexual abuse and (b) the role of delay between the offence(s) and the trial in these appeals. Appeals listed in the Victorian Court of Appeal in Australia between 2004 and 2014 were identified. Data were extracted for a number of variables including the appeal's success and the delay between the first offence and the trial. Of the 238 appeals identified, 118 (49.6%) were successful. Legislative reform showed the only significant difference between successful and unsuccessful appeals: There were more successful appeals than expected following legislative changes in 2006. Delay was raised as a ground for appeal in 11 of the 118 successful cases. Delay was associated with the ages of the victims and offenders, sex of the victims, and the victim-offender relationship. Overall, the results do not appear consistent with the goal of the reforms, which was to avoid appeals and retrials that may have occurred as a result of judicial error. Future research should determine whether the trend towards higher success of appeals is continuing, particularly in light of further legislative changes.

The Relationship Between Children's Age and Disclosures of Sexual Abuse During Forensic Interviews

Children's disclosures of sexual abuse during forensic interviews are fundamental to the investigation of cases. Research examining the relationship between age and disclosure has shown mixed results; the aim of the current study was to clarify and extend our knowledge by modeling linear, quadratic, and interaction effects of age on disclosure. Child sexual abuse reports made by children, their caregivers, or mandated reporters over a 12-month period to police in one state of Australia were examined. Of the 527 children (age range 3-16 years) offered a forensic interview, 81% disclosed abuse during it. The other 19% did not disclose or refused the interview. Age had both linear and quadratic effects, whereby disclosure increased with age until 11 years, after which disclosure decreased with age to 16 years. The effect of age on disclosure was moderated by five variables: abuse severity, the child-suspect relationship, suspects' violence histories, delay of report to police, and children's previous disclosures. Particular groups of children had lower likelihoods of disclosing abuse in forensic interviews than others, such as adolescents who alleged abuse against suspects with histories of violent offending. By identifying these groups, targeted strategies may be developed to help increase their disclosure rates.

Professionals' Perspectives about the Challenges of Using Interpreters in Child Sexual Abuse Interviews

Interpreters play a crucial role in many investigative interviews with child complainants of sexual abuse; however, little has been written about the interpreting process from the perspective of the interviewers. This study elicited interviewers' perspectives about the challenges of using interpreters, with the aim of understanding how investigative interviews could be improved. The participants consisted of 21 investigative interviewers and prosecutors of child abuse cases (from a range of jurisdictions) who use interpreters on a regular basis. Thematic analysis of semi-structured interviews with the professionals about the interpreting process revealed two main challenges particular to child abuse interviews, namely the interpreters' lack of preparedness to deal with the traumatic and sensitive nature of children's abuse histories, and an insufficient understanding of 'best-practice' child interview process. The recommendations focus on the need for more specialised training for, and screening of, interpreters, and more extensive use of pre-conferencing to familiarise children with the interpreter-mediated interview process.

Legal Representatives' Opinions regarding Psychologists Engaging in Expert Witness Services in Australian Courts and Tribunals

Legal representatives engage psychologists to provide expert witness opinions about a number of factors, including the psychological factors that may have contributed to the perpetrator's behaviour and the likelihood of reoffending. Although this evidence can affect the outcome of proceedings, little is known about how the experts who provide it are chosen or about the quality of their services. This paper explored legal representatives' reasons for engaging psychologists as expert witnesses, how they choose these experts, and their opinions about the expertise provided. Questions were also asked about the features of good and poor written and oral expert testimony. The results show that the majority of legal representatives engage psychologists who are usually chosen through referrals from colleagues and others. The legal representatives in the present sample had little awareness about the different backgrounds of experts (e.g. clinical vs forensic psychology). These results have implications for psychologists who provide expert evidence and the legal representatives who engage them.

Identifying the characteristics of child sexual abuse cases associated with the child or child's parents withdrawing the complaint

Most child sexual abuse cases do not result in a full trial or guilty plea; rather, case attrition occurs at earlier stages of the criminal justice system. One reason for the attrition of these cases is the withdrawal of complaints, by children or their caregivers. The aim of the current study was to determine the case characteristics associated with complaint withdrawal in child sexual abuse cases by the child or his or her parents once a report has been made to authorities. All child sexual abuse incidents reported to authorities in one jurisdiction of Australia in 2011 were analyzed (N=659). A multinomial logistic regression was used to predict the following case outcomes: (1) withdrawn by the child or his or her parents, (2) exited for other reasons (e.g., the alleged offender was not identified, the child refused to be interviewed), and (3) resulted in a charge. Five predictors significantly added to the prediction of case outcome: child age, suspect gender, suspect age, child-suspect relationship, and abuse frequency. These results should contribute to the design of interventions in order to reduce complaint withdrawals if these withdrawals are not in the child's best interests.

A qualitative evaluation of the challenges faced by dieticians when interviewing children

BACKGROUND

Investigative interviewing is a critical and challenging skill involved in the assessment and design of appropriate interventions for children's dietary problems. The current study provided an evaluation of the challenges faced by professional dieticians when conducting child investigative interviews, in the hope that this would provide a framework for the development of further guidance and resources in this important area.

METHODS

Fourteen professional dieticians were interviewed; they were asked about the information that they needed to elicit from children in particular situations and the questions that they would ask to do so. They were also asked to describe the strengths and limitations of the techniques that they used.

RESULTS

The results revealed that professionals faced three main challenges. The first challenge was eliciting information from children who did not want to answer questions. The second challenge was determining the level of accuracy in children's (and caregivers') responses. The third challenge was eliciting very specific information in particular situations, such as determining the cause of an allergic reaction.

CONCLUSIONS

Overall, professionals had difficulty articulating the questions that they would use to elicit the information that they required; indeed, their responses focused more on the content that they wanted to elicit (such as specific details) rather than the overall process that they would use to do so. Professionals may benefit from the development of guidelines to assist them in their interviews with children, based on what is currently known about interviewing children generally.

The Effects of Practice on Children's Ability to Apply Ground Rules in a Narrative Interview

Despite the widespread use of ground rules in forensic interview guidelines, it is unknown whether children retain and apply these rules throughout narrative interviews. We evaluated the capacity of 260 five- to nine-year-olds to utilize three ground rules. At the beginning of the interview all children heard the rules; half also practiced them. Children then responded to open-ended prompts about a repeated laboratory event and were assessed for their application of the rules. Logistic regressions revealed that practice only benefitted the use of the "don't know" rule. Although the children accurately answered "don't understand" and "correct me" practice questions, practice appeared to give no greater benefit than just hearing the rules. Results suggest that the current format of ground rule practice in interview guidelines is appropriate for the "don't know" rule, but the other rules may require more extensive practice with this age group.

Retrieval-Induced Forgetting of Performed and Observed Bizarre and Familiar Actions

To investigate whether people show retrieval-induced forgetting (RIF) for bizarre and familiar actions that they performed or observed, three experiments were conducted. In Experiment 1, participants performed bizarre and familiar actions with different objects during learning (e.g., pencil: balance the pencil across the cup, sharpen the pencil). They repeatedly performed a set of the bizarre or familiar actions during retrieval practice. After a distracter task, participants’ cued recall was tested. Participants showed RIF for both bizarre and familiar actions. In Experiment 2, half of the participants performed the bizarre and familiar actions themselves; the other half observed the experimenter performing the actions. Replicating the results of Experiment 1, participants who performed the actions showed RIF for bizarre and familiar actions. In contrast, participants who observed the actions did not show RIF for either action type. Experiment 3 examined whether this lack of RIF for observed actions occurred due to a lack of active recall during retrieval practice; it did. Overall, the three experiments demonstrated RIF for both bizarre and familiar performed and observed actions. A distinctiveness account of the results is provided.

Do people's motives influence their susceptibility to imagination inflation?

People are motivated to remember past autobiographical experiences related to their current goals; we investigated whether people are also motivated to remember false past experiences related to those goals. In Session 1, we measured subjects' implicit and explicit achievement and affiliation motives. Subjects then rated their confidence about, and memory for, childhood events containing achievement and affiliation themes. Two weeks later in Session 2, subjects received a "computer-generated profile" based on their Session 1 ratings. This profile suggested that one false achievement event and one false affiliation event had happened in childhood. After imagining and describing the suggested false events, subjects made confidence and memory ratings a second time. For achievement events, subjects' explicit motives predicted their false beliefs and memories. The results are explained using source monitoring and a motivational model of autobiographical memory.

Imagining nice and nasty events in childhood or adulthood: recent positive events show the most imagination inflation

We explored whether event recency and valence affect people's susceptibility to imagination inflation. Using a three-stage procedure, subjects imagined positive and negative events happening in their distant or recent past. First, subjects rated how confident they were that they had experienced particular positive and negative events in childhood or adulthood using a Life Events Inventory (LEI). Two weeks later, they imagined two positive and two negative events from the LEI. Finally, they rated their confidence on the LEI a second time. For positive events, subjects showed more imagination inflation for adulthood than childhood events. For negative events, they showed no difference in imagination inflation for adulthood and childhood events. We discuss factors that may influence source confusions for memories of the past and highlight directions for future research.

Memory on the beach: an Australian memory (and hypnosis) laboratory

The memory (and hypnosis) lab at the University of New South Wales investigates a broad range of memory topics. We try to find innovative methods from cognitive and clinical psychology to address theoretical and empirical questions about memory. We aso use hypnosis as one major methodological tool in our investigations of memory (as well as other cognitive processes). In this paper, we review the projects currently underway in our memory (and hypnosis) lab.

Psychotropic placebos create resistance to the misinformation effect

Can a placebo for a psychotropic drug help participants resist the misinformation effect? To answer this question, we gave participants a mixture of baking soda and water and told half of them that the mixture was a cognition-enhancing drug called R273 and told the other half that it was an inactive version of the drug. Shortly thereafter, all participants took part in a three-stage misinformation experiment. Compared with participants who were told that they had taken the placebo, the participants who were told that they had taken the drug reported improved cognitive abilities and were less susceptible to the misinformation effect. We provide source-monitoring and mindfulness accounts of our findings.

False claims about false memory research

Pezdek and Lam [Pezdek, K. & Lam, S. (2007). What research paradigms have cognitive psychologists used to study "False memory," and what are the implications of these choices? Consciousness and Cognition] claim that the majority of research into false memories has been misguided. Specifically, they charge that false memory scientists have been (1) misusing the term "false memory," (2) relying on the wrong methodologies to study false memories, and (3) misapplying false memory research to real world situations. We review each of these claims and highlight the problems with them. We conclude that several types of false memory research have advanced our knowledge of autobiographical and recovered memories, and that future research will continue to make significant contributions to how we understand memory and memory errors.

Using source cues and familiarity cues to resist imagination inflation

To investigate whether people can resist imagination inflation--the imagination-induced increased confidence that fictitious childhood events really happened--we gave them different types of cues. In a three-stage procedure, participants: (1) rated their confidence that a list of childhood events had happened to them, (2) imagined some of these events, and (3) made confidence ratings a second time. Subjects received either no cues about the source of the imagined event, an additional source cue (perspective), an additional familiarity cue (a plausibility questionnaire), or both cues. Only subjects who had both types of cues resisted imagination inflation. These results suggest that additional cues can sometimes safeguard people from becoming more confident that fictitious events were genuine experiences.

Imagination or exposure causes imagination inflation

To examine the effects of exposure to complex autobiographical events on imagination inflation, subjects performed a 3-stage procedure. First, they rated their confidence that a list of events had happened in their childhood. Second, subjects imagined and paraphrased complex fictitious events 0, 1, 3, or 5 times. Finally, they rated their confidence for the childhood events a second time. We found that subjects became more confident that the fictitious events really did happen in childhood, regardless of whether they were imagined or paraphrased. There was no repetition effect beyond that of a single exposure. Taken together with the results of other research, our data suggest that the greater processing fluency associated with the target events drives imagination inflation.

Examining memory for heterosexual college students' sexual experiences using an electronic mail diary

To examine memory for sexual expenences, the authors asked 37 sexually active, nonmonogamous, heterosexual college students to complete an e-mail diary every day for 1 month. The diary contained questions about their sexual behaviors. Six to 12 months later, they returned for a surprise memory test, which contained questions about their sexual experiences from the diary phase. They were asked about their sexual partners, the types of sexual experiences they had, and condom use. Participants underreported the number of partners they had, but they overreported both sexual experiences and condom use. The results have implications for both sexual health educators and for people who engage in high-risk sexual behaviors.

The power of the spoken word: sociolinguistic cues influence the misinformation effect

We investigated whether the sociolinguistic information delivered by spoken, accented postevent narratives would influence the misinformation effect. New Zealand subjects listened to misleading postevent information spoken in either a New Zealand (NZ) or North American (NA) accent. Consistent with earlier research, we found that NA accents were seen as more powerful and more socially attractive. We found that accents per se had no influence on the misinformation effect but sociolinguistic factors did: both power and social attractiveness affected subjects' susceptibility to misleading postevent suggestions. When subjects rated the speaker highly on power, social attractiveness did not matter; they were equally misled. However, when subjects rated the speaker low on power, social attractiveness did matter: subjects who rated the speaker high on social attractiveness were more misled than subjects who rated it lower. There were similar effects for confidence. These results have implications for our understanding of social influences on the misinformation effect.
