Memory conformity and suggestibility

Abstract

The present study examined whether the degree to which participants engage in memory conformity, which occurs when a person alters their memory report of an event to be consistent with another person, can be predicted by their levels of interrogative suggestibility (IS), which is the degree to which people are susceptible to altering their memory reports during questioning. Memory conformity was introduced by having participant and confederate pairs study words and then complete a social recognition test where they took turns to make judgements to the same items. When the participants responded after the confederate, they tended to conform to confederate's judgements regardless of whether the confederate had made a correct or incorrect response. IS was measured using the Gudjonsson Suggestibility Scale 2. This scale allows separate measures of Yield, which is a measure of how susceptible people are to altering their memory reports of events as a result of leading questions, and Shift, which is a measure of how susceptible people are to changing responses to questions when placed under pressure to do so. Only Yield was a significant predictor of memory conformity.     

Understanding Children's Use of Secrecy in the Context of Eyewitness Reports

To investigate socioemotional influences on children's eyewitness accuracy, we examined children's reports for activities they were motivated to conceal. Forty-eight 3–6-year-old children participated in a standardized play session with their mothers. Half of the children were told by an experimenter not to play with certain toys, but did so at the urging of their mothers, who told their children to keep the play activities secret. The remaining children were not restricted from playing with the toys, nor told by their mothers to keep the play activities secret. Later, all children were interviewed about the activities with free narrative and detailed questions. Half were given an interview that consisted of highly suggestive questions; half were given an interview consisting of specific, less suggestive questions. Results indicated that older children who were instructed to keep events secret withheld more information than did older children not told to keep events secret. Younger children's reports were not significantly affected by the secret manipulation. There were no significant effects associated with interview type. We discuss implications for understanding the development of children's knowledge and use of secrecy, and applications of the research to issues that arise when child witnesses give reports in legal contexts.     

The problem of interviewing drug addicts in custody: A study of interrogative suggestibility and compliance

Abstract

The interrogation of drug addicts in custody presents a problem. The reliability of confessions made either under the influence of drugs or during drug withdrawal may be adversely affected. This study explores the effect of drug use and drug withdrawal on interrogative suggestibility and compliance. These two psychological factors are relevant to erroneous testimony. The interrogative suggestibility and compliance of heroin addicts on an inpatient drug unit were measured on opiates, whilst withdrawing from opiates and drug free. The interrogative suggestibility and compliance of the group of subjects as a whole did not differ significantly in these three conditions. However the results did suggest that a subgroup of vulnerable individuals may have been more suggestible when under the influence of opiates. Further work is needed to clarify these results and to aid professionals assessing fitness for interview and cases of retracted confessions.     

Theory and practice in interviewing young children: A study of Norwegian police interviews 1985–2002

Abstract

Has the increased public and professional awareness of the challenges of interviewing children in forensic contexts led to changes and improvements in police interviewing practices? A representative sample (n=91) of police interviews conducted during the period of 1985–2002 from a large Norwegian police district was analysed. The results indicated that interviewer strategies have improved; there was a decrease in the use of suggestive, yes/no and option-posing questions and this decrease was accompanied by a comparable increase in the use of cued recall questions. The frequency of open-ended invitations was low and did not change much over time. Factors that might have led to the observed changes are briefly discussed.     

When Does Quality Count?: Perceptions of Hearsay Testimony About Child Sexual Abuse Interviews

This study assessed how the quality of a sexual abuse investigative interview with a child and the age of the child influence jurors reactions to either the original interview with the child or to testimony by an adult hearsay witness (the interviewer). Participants (N = 360) were randomly assigned to 1 of 12 conditions in a 2 (type of testimony:hearsay testimony vs. child interview) × (interview quality: poor, typical, or good) × (age of the child: 4 years old vs. 10 years old) factorial design. Participants reached individual verdicts, answered a series of questions, and then deliberated in a group with five other participants. As predicted, jurors in the child interview conditions were more likely to find the defendant guilty if they read the good interview than if they read either the poor or the typical interview, but in the hearsay conditions verdicts did not significantly differ by interview quality. These findings suggest that there is a significant loss of information when the testimony of a hearsay witness is used in place of the actual interview with the child, and call into question the appropriateness of admitting hearsay testimony by interviewers.     

Simulations of child sexual abuse interviews using avatars paired with feedback improves interview quality

We tested whether simulated child sexual abuse (CSA) interviews with computer-generated child avatars could improve interview quality. Feedback was provided not only on question types, as in previous research, but also on whether the conclusions drawn by the interviewers were correct. Twenty-one psychology students (average age M = 24.5) interviewed four different avatars which had a simulated story of either abuse or non-abuse. The participants were randomly divided into two groups: one received feedback on question types and conclusions after each simulated interview and the other one did not receive any feedback. Avatars revealed pre-defined ‘memories’ as a function of algorithms formulated based on previous empirical research on children's suggestibility. The feedback group used more open-ended and fewer closed questions. They also made more correct conclusions and found more correct details in the last two interviews compared to the no-feedback group. Feedback on both the question types and conclusions in simulated CSA interviews with avatars can improve the quality of investigative interviews in only one hour. The implications for training practice were discussed.     

Mock-juror reactions to multiple interview presentation and rapport-building

ABSTRACT

In the UK and some US states, video-recorded investigative interviews of child victims/witnesses can be presented in court as the child’s evidence-in-chief. However, there is scarce advice or research on the effect that presenting different sections of the interviews may have on juror perceptions of the child’s testimony. Two aspects of testimony presentation are examined here: first, whether to show the rapport-building phase of the interview, and second, the presentation of multiple interviews (i.e. more than one interview with the same child). Participants (n?=?103) informed they were watching two interviews of the same child separated by a week had more positive perceptions of the child’s testimony than those informed they were watching just one extended interview with a ten-minute break. Also, those watching the rapport-building phase had less positive perceptions of the child’s testimony than those who did not watch this phase. Participants’ perceptions of the interviewer and their case progression decisions were mainly not related to the above presentational differences. Thus, (i) mock-jurors were not inherently biased against multiple interviews and (ii) decisions regarding whether or not to show the rapport-building phase in court may have significant effects on jurors’ perceptions of the child and their testimony.

The relationship between intelligence,memory and interrogative suggestibility in young offenders

Abstract

The study investigated the relationship between interrogative suggestibility and relevant cognitive factors as proposed by Gudjonsson and Clark (1986). The subjects were fifty-eight adolescent young offenders resident in a national children's centre with secure facilities. All were administered the Gudjonsson Suggestibility Scale and the Wechsler Intelligence Scale for Children. Interrogative suggestibility correlated negatively with intelligence and recall memory. Limited evidence of range effects was found for the relationship between intelligence and suggestibility, but not for the relationship between recall memory and suggestibility.     

Individual differences in interrogative suggestibility: life adversity and field dependence

Since the turn of the century much research has explored the concept of interrogative suggestibility, with recent research highlighting a sizeable link between the reported experience of negative life events (NLEs) and performance on the Gudjonsson Suggestibility Scale 1 (GSS1). The present study sought to reinvestigate the previously found novel relationship, as well as explore the role of field dependence as a possible coping mechanism implemented during interview by such vulnerable interviewees. As expected, highly significant correlations between NLEs and the suggestibility components of the GSS emerged. Field dependence, however, failed to correlate significantly with either NLE or GSS scores. Nonetheless, some additional findings relating to age, NLEs, and shift scores on the GSS were noted, which may help further our understanding of the NLE to interrogative suggestibility relationship. A new group of vulnerable interviewees, who are as yet unrecognized by the police or courts, has also been identified.     

Mental reinstatement of context with child witnesses: does it matter whether context is reinstated ‘out loud’?

Abstract

In this study we examined the impact of two types of mental reinstatement of context instructions in facilitating children's recall of a staged event across two stages of development. Specifically, a 2 × 3 factorial design was utilised incorporating two age groups (6- and 12-year-olds) and three interview conditions (standard recall, mental reinstatement where the child was instructed to reinstate the context ‘out loud’, and mental reinstatement without the explicit ‘out loud’ instruction). Overall, mental reinstatement instruction led to more correct and fewer incorrect responses than the standard recall instruction. The effect of mental reinstatement was similar across the age groups and irrespective of whether the child was asked to reinstate ‘out loud’. Beneficial effects of the technique, however, were only evident for cued-recall questions as opposed to free-narrative responses. The implications of these findings and directions for future research are discussed.     

Size doesn't matter: emotional content does not determine the size of objects in children's drawings

Abstract

In Experiment 1 we examined whether children spontaneously alter the size of objects in their drawings of emotionally-laden events. To do this, we evaluated children's drawings of their own personal, past experiences. Children were asked to draw a picture of an event that had made them happy and an event that had made them sad. We found no differences in the size of object that children drew in their positive and negative emotional events. In Experiment 2, we asked adults with and without clinical training to discriminate children's drawings of happy events from their drawings of sad events. There was no difference in the accuracy of raters as a function of clinical expertise. Moreover, performance for both groups was at chance when we removed drawings with specific emotional indicators from the set (e.g. smiles or tears). We conclude that the emotional interpretation of drawings on the basis of the size of objects in that drawing is fraught with difficulty. We question the projective use of drawings in forensic and clinical practice.     

Differences in suggestibility between 5–6 and 10–11 year olds: The relationship with self confidence

Abstract

Differences in suggestibility and recall between 5–6 and 10–11 year olds were investigated. It was hypothesized that younger children would be more suggestible than older children and that differences in self confidence between older and younger children would influence these differences. It was also predicted that older children would recall more information than younger children, and that this age difference would be less strongly influenced by self confidence. Forty-one 5 and 6 and fifty-six 10 and 11 year olds were interviewed about a video they had witnessed. Several factual and misleading questions were asked, and the percentage of correct answers to the factual questions (to measure recall) and the percentage of incorrect answer to the misleading questions (to measure suggestibility) were calculated. The level of self confidence of the children was measured with six items of the Behavioural Academic Self Esteem Scale (BASE), reflecting self confidence. The outcomes supported the hypotheses: Younger children were more suggestible than older children and this difference disappeared when controlled for self confidence. Older children gave mere information about the event than younger children, and these age differences were, to much less extent, influenced by their self confidence.     

A systematic review on the relationship between self-esteem and interrogative suggestibility

Some factors, such as age, learning disability and mental health difficulties, have been identified as making police suspects more vulnerable to suggestibility and false confessions during interview. However, there has been no systematic review on the association between self-esteem and suggestibility. Seven electronic bibliographic databases and reference lists of previous literature reviews of suggestibility in children were searched. Selected studies were quality assessed using pre-defined criteria before data were extracted. Electronic searches yielded 1914 hits. Of these, 685 duplicates, 1181 irrelevant references and 39 references that did not meet the inclusion criteria were removed. Nine publications were included in the review. Significant correlations between self-esteem and suggestibility, most notably on the Yield 1 subscale of the GSS, were found but four of the nine studies found no significant correlation. The prevalent use of self-report measures and lack of clarity in defining self-esteem limit the validity of those studies.     

Juvenile Sex Offenders: Differences between Group and Solo Offenders

We report on findings from a study into differences in personality and background characteristics between juvenile sex offenders who commit their sex offenses on their own and those who do so in a group. Solo offenders were found to score significantly higher on neuroticism, impulsivity and sensation seeking, but scored lower on sociability. In addition, the solo offenders in the sample were more often recidivists for sexual offenses, and were more often themselves a victim of a sexual offense. Solo offenders were significantly older than juveniles who had committed a sexual offense with a group. On the basis of these results we recommend differential treatment for the two types of offenders.
