Eyewitness Testimony in Autism Spectrum Disorder: A Review

'Just knowing it's there gives me comfort': Exploring the benefits and challenges of autism alert cards

This study explores the experiences and outcomes associated with the use of an autism alert card, developed to assist with the complexities of autism disclosure. A mixed-methods approach was employed, surveying 272 Australian participants, including 136 Autistic adults, 128 parents or caregivers of Autistic children and eight Autistic children. Our research aimed to understand who is using the alert card, in what contexts and the differences in perceptions of the card between Autistic individuals and their parents. Findings indicate that about half of the participants used the card, primarily in public settings such as transport (17%), healthcare (16%) and retail (16%). The card was seen as a valuable tool for facilitating communication, reducing the need for verbal explanations and providing a sense of security. However, challenges were reported, including societal disbelief, patronising attitudes and internalised stigma, highlighting the need for greater public education on autism. Despite these challenges, majority of participants (76.2%) would recommend the card. This research underscores the dual nature of autism alert cards as both beneficial and limited by societal attitudes, emphasising the need for comprehensive training and awareness programmes to maximise their effectiveness.Lay abstractThis study looks at how people use and feel about autism alert cards, which help Autistic people communicate their diagnosis/identity. We surveyed 272 Australian people, including 136 Autistic adults, 128 parents of Autistic children and eight Autistic children. About half of the participants used the card after ordering it, mostly in public places such as public transport, healthcare settings and in retail settings. People found the card helpful because it made it easier to explain their needs without having to speak and provided them a sense of security. However, some people treated Autistic people poorly after being shown the card due to a lack of understanding about autism. Many participants felt that more education about autism is needed to improve how people react to the alert card. Despite these challenges, most participants (76.2%) would recommend the alert card to others. This research shows that while autism alert cards can be very helpful, their effectiveness depends on how well other people understand and accept autism. To make these cards work better, we need more training and awareness programmes for the general public and professionals such as doctors or police officers who may interact with Autistic people.

Effects of the narrative elaboration technique and open-ended rapport on accuracy of children's recall according to age

Introduction

This study explored the impacts of the narrative elaboration technique (NET) and open-ended rapport building on younger (n = 30, ages 5-6) and older (n = 30, ages 7-8) children's free recall and suggestibility.

Methods

Children were randomly assigned to either a NET condition or an open-ended rapport condition after engaging in a photo-taking play session with an experimenter. Then, a novel interviewer asked them about the play session. The effects of the experimental conditions on children's free recall and suggestibility were examined according to children's age groups.

Results

Results revealed that open-ended rapport played a more significant positive role in young children's free recall and suggestibility when compared to NET. No significant differences were observed in the effects of NET and open-ended rapport on older children's memory performance.

Discussion

Practical guidance is provided in terms of prioritizing open-ended rapport over NET to maximize young children's spontaneous and accurate recall.

Forensic interviews conducted with autistic adults in Japan: a review of the literature and directions for future research

The interviewing of victims, witnesses and suspects is important in helping resolve criminal investigations. In Japan, developments have recently occurred in the training of the police and their public prosecutors in these key tasks. Whilst literature exists on autism in Japan, studies examining police/public prosecutor interviews with autistic adults conducted in that country (and indeed, any other) remain scant. As elsewhere in the world, identification of those who manifest characteristics prevalent on the autism spectrum disorder (ASD) scale, has been found to be problematical to criminal justice professionals. To help address this deficit in understanding, we provide an overview of the literature concerning contemporary understanding of the challenges facing autistic adults as they attempt to reveal their verbal accounts, as well as suggested techniques when interviewing adults on the ASD scale during criminal investigations, offering lessons learned from research conducted around the world that provide potentially promising solutions for Japan.

Interviewing alleged victims with mild and moderate intellectual disabilities and autism: A field study of police-investigated cases of physical and sexual abuse in a Norwegian national sample

BACKGROUND

People with intellectual disabilities (IDs) or autism are at great risk of being victims of physical and sexual abuse. This study uses transcriptions of real-life investigative interviews to examine the interview techniques (e.g. question type) used in investigative interviews of these groups of alleged victims.

METHODS

A national sample of transcribed investigative interviews (N = 96) of alleged victims with mild ID (n = 48, age 5-70 years old), moderate ID (n = 18, age 14-43 years old) and autism (n = 16, age 5-50 years old) was analysed.

RESULTS

The study shows a preponderance of alleged sexual offences (70.7%) and reveals that open-ended questions account for only 2.6% of the total number of questions asked. The interviewers relied heavily on yes/no (53.4%) and directive questions (32.2%). Suggestive questions (8.6%) were frequently used.

CONCLUSIONS

The use of question type varied considerably within and across the diagnostic group. The study reveals the need for a more in-depth analysis of variables that influence investigative interviews of people with cognitive impairments.

Interviewing autistic adults: Adaptations to support recall in police, employment, and healthcare interviews

Recalling specific past experiences is critical for most formal social interactions, including when being interviewed for employment, as a witness or defendant in the criminal justice system, or as a patient during a clinical consultation. Such interviews can be difficult for autistic adults under standard open questioning, yet applied research into effective methods to facilitate autistic adults’ recall is only recently beginning to emerge. The current study tested the efficacy of different prompting techniques to support autistic adults’ recall of specific personal memories; 30 autistic and 30 typically developing adults (intelligence quotients > 85) were asked to recall specific instances from their past, relevant to criminal justice system, healthcare, and employment interviews. Questions comprised ‘open questions’, ‘semantic prompting’ (where semantic knowledge was used to prompt specific episodic retrieval) and ‘visual–verbal prompting’ (a pie-diagram with prompts to recall specific details, for example, who, what, and where). Half the participants received the questions in advance. Consistent with previous research, autistic participants reported memories with reduced specificity. For both groups, visual–verbal prompting support improved specificity and episodic relevance, while semantic prompting also aided recall for employment questions (but not health or criminal justice system). Findings offer new practical insight for interviewers to facilitate communication with typically developing and autistic adults.

Brief Report: Autistic Adults Assign Less Weight to Affective Cues When Judging Others' Ambiguous Emotional States

Understanding other people's emotional states involves integrating multiple sources of information, such as someone's smile (affective cue) with our knowledge that they have passed an exam (situational cue). We explored whether autistic adults display differences in how they integrate these cues by showing participants videos of students receiving their exams results. Our results suggest autistic adults generally perform as neurotypical participants when identifying and integrating affective and situational cues. It was only in certain unfamiliar and ambiguous social situations that autistic adults assigned less weight to affective cues compared to situational cues when judging other people's emotional states.

Metacognitive Monitoring and Control of Eyewitness Memory Reports in Autism

Providing eyewitness testimony involves monitoring one's memory to provide a detailed and accurate account: reporting details likely to be accurate and withholding potentially inaccurate details. Autistic individuals reportedly experience difficulties in both retrieving episodic memories and monitoring their accuracy, which has important implications for eyewitness testimony. Thirty autistic and 33 IQ‐matched typically developing (TD) participants viewed a video of a mock bank robbery followed by three phases of questions (with judgments of confidence). In Phase 1, participants freely generated the granularity of their responses (i.e., fine‐ or coarse‐grained). In Phase 2, participants answered the same questions but provided both a fine‐ and a coarse‐grained answer. In Phase 3, participants were instructed to maximize accuracy over informativeness by selecting one of their Phase 2 answers as their final answer. They either received the questions socially (from the experimenter) or answered them online. There were no group differences in accuracy or metacognitive monitoring, with both autistic and TD witnesses demonstrating: (a) a strong preference for reporting fine‐grained details at the expense of accuracy; (b) improved though still suboptimal grain size reporting when instructed to maximize accuracy over informativeness; (c) effective accuracy monitoring; and (d) higher overall accuracy when questions were delivered socially. There was, however, a subtle difference in metacognitive control, with autistic witnesses performing more poorly than TD witnesses when questions were delivered socially, but not when they were delivered online. These findings contrast with evidence suggesting that autism is marked by impairments in episodic memory and metacognitive monitoring and control. Autism Res 2020, 13: 2017‐2029. © 2020 The Authors.

Lay Summary

Autistic people have been reported to experience subtle difficulties in monitoring and regulating their information reporting, which has important implications for providing eyewitness testimony. We found that autistic witnesses' testimony comprised a similar level of detail and accuracy as non‐autistic witnesses' accounts. However, autistic people found it difficult to optimize their testimony when the questions were delivered socially—but not when they answered the questions online. © 2020 The Authors.

The narrative coherence of witness transcripts in children on the autism spectrum

BACKGROUND AND AIMS

Autistic children often recall fewer details about witnessed events than typically developing children (of comparable age and ability), although the information they recall is generally no less accurate. Previous research has not examined the narrative coherence of such accounts, despite higher quality narratives potentially being perceived more favourably by criminal justice professionals and juries. This study compared the narrative coherence of witness transcripts produced by autistic and typically developing (TD) children (ages 6-11 years, IQs 70+).

METHODS AND PROCEDURES

Secondary analysis was carried out on interview transcripts from a subset of 104 participants (autism = 52, TD = 52) who had taken part in a larger study of eyewitness skills in autistic and TD children. Groups were matched on chronological age, IQ and receptive language ability. Coding frameworks were adopted from existing narrative research, featuring elements of 'story grammar'.

OUTCOMES AND RESULTS

Whilst fewer event details were reported by autistic children, there were no group differences in narrative coherence (number and diversity of 'story grammar' elements used), narrative length or semantic diversity.

CONCLUSIONS AND IMPLICATIONS

These findings suggest that the narrative coherence of autistic children's witness accounts is equivalent to TD peers of comparable age and ability.

Effects of Delay, Question Type, and Socioemotional Support on Episodic Memory Retrieval by Children with Autism Spectrum Disorder

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.

The Influence of task Demands, Verbal Ability and Executive Functions on Item and Source Memory in Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is generally associated with difficulties in contextual source memory but not single item memory. There are surprising inconsistencies in the literature, however, that the current study seeks to address by examining item and source memory in age and ability matched groups of 22 ASD and 21 comparison adults. Results show that group differences in source memory are moderated by task demands but not by individual differences in verbal ability, executive function or item memory. By contrast, unexpected group differences in item memory could largely be explained by individual differences in source memory. These observations shed light on the factors underlying inconsistent findings in the memory literature in ASD, which has important implications for theory and practice.

Social Conformity in Autism

Humans are extremely susceptible to social influence. Here, we examine whether this susceptibility is altered in autism, a condition characterized by social difficulties. Autistic participants (N = 22) and neurotypical controls (N = 22) completed a memory test of previously seen words and were then exposed to answers supposedly given by four other individuals. Autistic individuals and controls were as likely to alter their judgements to align with inaccurate responses of group members. These changes reflected both temporary judgement changes (public conformity) and long-lasting memory changes (private conformity). Both groups were more susceptible to answers believed to be from other humans than from computer algorithms. Our results suggest that autistic individuals and controls are equally susceptible to social influence when reporting their memories.

Sex Differences in Body Ownership in Adults With Autism Spectrum Disorder

A strong male prevalence has been observed in autism spectrum disorder (ASD) since its definition, but the behavioral manifestations of sex disparity have yet to be clarified. Here, we investigate sex differences in the perception of the Numbness Illusion (NI), a procedure based on a tactile conflict, in adults with ASD and with typical development. We aim to assess if women and men with ASD perceive NI-dependent body ownership differently and whether sex differences emerge in individuals with typical development. To elicit the NI, participants pressed their right-hand palm against the confederate's hand and stroked with the thumb and the index finger of their left hand the joined index fingers in a synchronous or asynchronous way. Results reveal that women with ASD present a reversed and atypical pattern for the NI compared to men with ASD and a group of matched controls. In particular, women with ASD report a stronger illusion than men with ASD, that is more evident in the asynchronous conditions. In the asynchronous condition, women in the ASD group report stronger NI as compared to women and men in the Control group, whereas men with ASD only to men in the Control group. In the typical sample, the NI emerges only in the synchronous condition and no sex difference is observed. We discuss our results in terms of potential advantage of women in sociality and sensory information processing that might lead women with ASD to use different modalities to solve the illusion compared to men with ASD. In sum, these outcomes describe sex differences in individuals with ASD in the domain of illusory perception. This may be used in the future to support the characterization of the female phenotype of autism.

Autistic spectrum disorder and offending behaviour – a brief review of the literature

Purpose

The purpose of this paper to synthesise much of the existing research on autistic spectrum disorder (ASD) and offending behaviour.

Design/methodology/approach

It considers three key areas, namely, first, a discussion about the nature of ASD and how it might be related to offending behaviour; second, a brief commentary about the prevalence of this population; and, finally, an exploration of the effective management and possible treatment outcomes.

Findings

Methodological limitations have resulted in variable findings which has hindered our understanding of this population. Some of the research is based on small, highly specialist samples making prevalence difficult to measure. The link between ASD and offending is still not well understood, and despite advances in staff training, awareness amongst practitioners remains an underdeveloped area, thus yielding variable treatment outcomes.

Originality/value

This review continues to demonstrate the urgent need for robust research in order to better understand the link between ASD and offending behaviour, to provide tailored, needs-led interventions, and reduce the risk of offending amongst this group as a whole.

The clinical utility of social information processing theory in assessing and treating offenders with autism spectrum disorder

Purpose

Social deficits are central within conceptualisations of autism spectrum disorder (ASD), and separately linked to offending behaviour. Social problem-solving interventions are often used with offenders, but little research has examined the social information processing (SIP) skills of individuals with ASD and a history of criminal offending behaviours. The paper aims to discuss this issue.

Design/methodology/approach

This conceptual paper will introduce the SIP model, review SIP research as applied to those with ASD and in forensic populations, and further consider the relevance to the assessment and treatment of offenders with ASD.

Findings

Difficulties in all areas of the SIP model are noted in ASD and research suggests these difficulties may be directly linked to behaviour.

Practical implications

It is possible that identifying SIP abilities and deficits could improve the effectiveness of rehabilitation programmes for this group.

Originality/value

This paper reviews the utility of social information models in the offending behaviour of people with ASD.

Recall of a live and personally experienced eyewitness event by adults with autism spectrum disorder

The aim of the present study was to (a) extend previous eyewitness research in autism spectrum disorder (ASD) using a live and personally experienced event; (b) examine whether witnesses with ASD demonstrate a facilitative effect in memory for self- over other-performed actions; (c) explore source monitoring abilities by witnesses with ASD in discriminating who performed which actions within the event. Eighteen high-functioning adults with ASD and 18 age- and IQ-matched typical counterparts participated in a live first aid scenario in which they and the experimenter each performed a number of actions. Participants were subsequently interviewed for their memory of the event using a standard interview procedure with free recall followed by questioning. The ASD group recalled just as many correct details as the comparison group from the event overall, however they made more errors. This was the case across both free recall and questioning phases. Both groups showed a self-enactment effect across both interview phases, recalling more actions that they had performed themselves than actions that the experimenter had performed. However, the ASD group were more likely than their typical comparisons to confuse the source of self-performed actions in free recall, but not in questioning, which may indicate executive functioning difficulties with unsupported test procedures. Findings are discussed in terms of their theoretical and practical implications.
