Effects of interviewer behavior on accuracy of children's responses

Previous research has shown that certain interviewer behaviors can evoke inaccurate answers by children. In the current study, we examined the effects of approving and disapproving statements on the accuracy of 3 children's answers to questions in an interview (Experiment 1). We then evaluated 3 questioning techniques that may be used by interviewers during a forensic interview in which a child provides eyewitness testimony (Experiment 2). All participants responded with more inaccurate answers when approving statements followed inaccurate information and disapproving statements followed accurate information in Experiment 1. During Experiment 2, 1 participant responded most inaccurately when she was requestioned after providing an initial answer, whereas the remaining 2 participants responded most inaccurately when the interviewer provided cowitness information and suggestive questions.     

The corroboration requirement in child sex abuse cases

The sharp rise in reports of child abuse has led to efforts to protect children in family courts in child protective proceedings. Hearsay evidence of a child's prior statements may be admitted in child protective proceedings, but such evidence is legally insufficient to support an adjudication of abuse without corroborative evidence. Courts have admitted expert psychological, psychiatric or social work testimony about the child sex abuse syndrome as sufficient corroborative evidence. The testimony is called “validation” testimony. The scientific basis for such validation testimony in the absence of a disclosure by the child is very weak. Courts have also tended to accept the most minimal evidence as corroboration of the child's out-of-court statements, including other hearsay evidence. The socially valuable policy of protecting children by admitting weak evidence, such as validation testimony, or other hearsay, should be reviewed to ensure the evidence meets criteria of reliability in order to minimize erroneous determinations.     

Predicting changes in children's self-perceptions of academic competence: a naturalistic examination of evaluative discourse among classmates

Classroom discourse was examined as a predictor of changes in children's beliefs about their academic capabilities. Kindergarten, first-grade, and second-grade students (N = 106) participated in 2 waves of data collection, approximately 1 year apart. During the 1st year of the study, children's verbal interactions with their classmates were observed and recorded. Children rated their self-perceptions of academic competence during the 1st and 2nd years. Analyses revealed that changes over time in children's competence perceptions could be predicted from the types of statements that children made and had directed toward them by classmates. Examining sequences of child and classmate statements proved helpful in explaining the observed changes in children's perceptions of competence.     

Tell Me Everything You Discussed: Children's Memory for Dyadic Conversations after a 1-Week or a 3-Week Delay

In child abuse investigations, children are often asked to recount previous conversations related to the allegations (i.e., “conversational testimony”). To explore children's ability to provide conversational testimony, we staged a semi-structured novel dyadic conversation between an adult researcher and 8-year-old children (n = 90). Children's gist recall and recognition memory for their own statements, their conversational partner's statements, and question–answer pairs were tested after either a 1-week or a 3-week delay. The results revealed that children recounted a minority of the conversation, although children recalled more after a short delay (7%) than after a long delay (4%). A majority of children's free recall statements were accurate (68%); however, approximately one-third of their free recall statements were incorrect. Children almost exclusively recounted their own statements, and rarely recalled any of the adult's statements or the question–answer pairs during free recall. Reports of the adult's statements and question–answer pairs increased with cued recall questioning, but remained minimal. During recognition testing, children were able to distinguish between true and false recognition items for their own statements and the adult's statements, but performed at chance level on recognition items concerning question–answer pairs. Forensic implications of the results are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Development of a Structured Psychiatric Interview for Children: Agreement Between Child and Parent on Individual Symptoms

To test the reliability of children's reporting as compared with that of their mothers, a highly structured psychiatric diagnostic interview was used with 307 subjects, ages 6 through 16. Another interviewer gave each mother a similar interview about the child. Responses of each mother-child pair to 168 questions were compared using the kappa statistic. Highest agreement was found on questions concerning symptoms that are concrete, observable, severe, and unambiguous. Mothers tended to report significantly more behavioral symptoms, and children more subjective symptoms. Reasons for low kappas and asymmetrical reporting of symptoms are discussed.     

Child,mother, and father evaluations of depression in psychiatric inpatient children

The agreement among children and their parents in evaluating the children's depression was examined in 48 families. Newly admitted inpatient children (ages 6–13) and their mothers and fathers independently completed selfreport and interview measures to assess severity and duration of the children's depression. The results indicated that different measures of depression completed by the same rater (child, mother, or father) were highly intercorrelated. Yet there was little or no relationship between childmother and child-father ratings of the children's depression for the same or related measures of depression. Children independently diagnosed (DSM III) as depressed rated themselves and were rated by their parents as more depressed than nondepressed children. Even so, children consistently rated themselves as less depressed across the measures than did their parents. Parent ratings of the children's depression and the correspondence of child-parent ratings varied as a function of several child and family variables, including child IQ, gender, race, and family welfare status.This investigation was supported in part by a Research Scientist Development Award (1 K02 MH00353) to the first author from the National Institute of Mental Health and by a Clinical Research Center Grant for the Study of Affective Disorders (5 P50 MH30915-05) from the National Institute of Mental Health.

Confidence judgments in event recall: developmental progression in the impact of question format

Two studies were conducted to examine developmental progression in children's and adults' ability to adequately monitor their own attempts to recall event details as well as the dependence of such metamemorial competencies on question formats. Eight and 10-year-old children as well as adults (Study 1, N=116; Study 2, N=60) rated their confidence when responding to specific questions about an observed event. Confirming most recent results, children and adults gave higher confidence ratings after correct than after incorrect answers. This ability, however, was limited to an unbiased question format. When being asked misleading questions, children's ability to differentiate was undermined, as reflected in equally high confidence judgments after correct and incorrect answers, even when the interview contained a mix of misleading and unbiased questions. When the interviewer "bombarded" the children with an uninterrupted series of misleading questions, children's difficulties appeared to be even more pronounced. These findings highlight the importance of the way in which questions are asked, and point to age-related progression in the relative impact of questioning style.     

Witnesses appearing live versus on video: effects on observers' perception,veracity assessments and memory

The study is an experiment examining how different presentation modes (live vs. video) affect observers' perception, veracity assessments and memory of witnesses and their statements. Three weeks after seeing a staged accident, six truth telling and six lying witnesses testified about the event. Mock jurors (N = 122) viewed the witnesses' testimony either live or on video and rated their perception of the witnesses' statement and appearance as well as the credibility of the witnesses. Live observers rated the witnesses' appearance in a more positive way and perceived them as being more honest than did video observers. Truth tellers were rated as having to think less hard than liars. Moreover, observers were not better than chance in assessing veracity, regardless of presentation mode. Live observers incorrectly believed they had a better memory of the witnesses' statements than video observers. Observers who had watched truthful statements showed a significantly better memory performance than observers who had watched deceptive statements. Copyright © 2005 John Wiley & Sons, Ltd.     

The Influence of Videoconference Technology and Interview Structure on the Recruiting Function of the Employment Interview: A Field Experiment

This field experiment examined whether interview medium and interview structure affects the attractiveness of organizations, interviewer friendliness and performance. Attractiveness ratings of 25 organizations were provided by 92 real job applicants, assigned to either a face–to–face (FTF) or a videoconference (VC) interview. An interview medium X structure interaction showed FTF applicants were attracted most to organizations who conducted their interviews with less structure, while VC applicants were more attracted to organizations using structured interviews. Interview structure had no effect on applicants’ perception of the interviewer’s performance; however, interviewers’ performance was rated higher for FTF than VC interviews. Applicants were more satisfied with their FTF performance in less structured interviews and more satisfied with their VC performance in highly structured interviews.     

Effect of Questioning Techniques and Interview Setting on Young Children's Eyewitness Memory

The goal of this research was to learn if supposed ineffective questioning techniques (e.g., question repetition within the interview) would reduce the accuracy of five-year-olds' eyewitness memory. In the first study, children viewed a slide show depicting a minor crime and were then interviewed either with a standard interview or one which incorporated ineffective questioning techniques. The results indicated that the type of interview did not affect children's eyewitness memory. In a second study, children were presented with the ineffective interview by an authoritative interviewer in a formal office setting. The results again indicated little influence of interview setting or question technique on children's eyewitness memory, identification accuracy, and suggestibility.     

Dynamics of verbal interaction between interviewer and child in interviews with alleged victims of child sexual abuse

A number (n = 27) of investigative interviews with children were analyzed with a view to explore the verbal dynamics between interviewer and child. Different types of interviewer utterances and child responses were defined, and the interrelationships between these were explored. The effectiveness of different interviewer utterances in eliciting information from children as well as the type of utterance the interviewer used to follow up an informative answer by the child were investigated. Option-posing and suggestive utterances made up for more than 50% of interviewer utterances, the proportion of invitations being only 2%. Invitations and directive utterances were associated with an increase in informative responses by the child, the adverse being true for option-posing and suggestive utterances. Interestingly, even after the child had provided an informative answer, interviewers continued to rely on focused and leading interviewing methods--in spite of a slight improvement in interviewing behavior.     

The Effects of the Application on Processing of Information From the Employment Interview.1

Subjects observed and evaluated employment interviews after forming initial impressions of the applicants' paper credentials. Contrary to expectations, differential recognition of interview content was not found to mediate the effects of the application on perceptions of the interview. Instead, interviewers showed a biased interpretation of the interview performance. Applicants were perceived as doing a better job in answering the questions of the interviewer, displaying more sales-consistent traits, and making more favorable statements the more favorable their paper credentials. Note taking led to more accurate recognition of information from the interview but did not attenuate the biasing effects of the application.     

Perceptions of Children's Credibility in Sexual Assault Cases1

Children's testimony often plays a central role in prosecutions of child sexual abuse. Nevertheless, research on jurors' perceptions of the credibility of child sexual assault victims remains limited. In three experiments, we examined mock jurors' reactions to children's testimony about sexual abuse. Participant jurors were exposed to videotaped or written scenarios of child sexual abuse trials and then rated victim credibility and defendant guilt. Analyses indicated that: (a) victim age was either inversely related or unrelated to perceptions of victim credibility, (b) women were more likely than men to find child victims credible, (c) corroborating testimony from a child victim increased the credibility of another child victim, and (d) exposure of participants to past criminal acts and other negative defendant character evidence heightened perceived victim credibility and defendant guilt. Implications for understanding jurors' reactions to child witnesses are discussed.     

How interviewers' nonverbal behaviors can affect children's perceptions and suggestibility

We conducted two studies to examine how interviewers' nonverbal behaviors affect children's perceptions and suggestibility. In the first study, 42 8- to 10-year-olds watched video clips showing an interviewer displaying combinations of supportive and nonsupportive nonverbal behaviors and were asked to rate the interviewer on six attributes (e.g., friendliness, strictness). Smiling received high ratings on the positive attributes (i.e., friendly, helpful, and sincere), and fidgeting received high ratings on the negative attributes (i.e., strict, bored, and stressed). For the second study, 86 8- to 10-year-olds participated in a learning activity about the vocal chords. One week later, they were interviewed individually about the activity by an interviewer adopting either the supportive (i.e., smiling) or nonsupportive (i.e., fidgeting) behavior. Children questioned by the nonsupportive interviewer were less accurate and more likely to falsely report having been touched than were those questioned by the supportive interviewer. Children questioned by the supportive interviewer were also more likely to say that they did not know an answer than were children questioned by the nonsupportive interviewer. Participants in both conditions gave more correct answers to questions about central, as opposed to peripheral, details of the activity. Implications of these findings for the appropriate interviewing of child witnesses are discussed.     

Beliefs and data on the relationship between consistency and accuracy of eyewitness testimony

Two studies concerned with consistency and accuracy of eyewitness testimony were conducted. In Study 1 potential jurors indicated the degree to which they considered that various witness on‐stand behaviours indicated testimonial accuracy. Witness statements that were inconsistent with previous statements were considered to be the strongest indicators of inaccuracy. Study 2 examined the relationship between consistency and accuracy of testimony. Witnesses viewed a film of a robbery and were interviewed twice (2 weeks apart) about the crime in a 4 (interview format)×2 (interview occasion) design. Regardless of whether consistency was operationalised in terms of direct contradictions between interviews, or degree of agreement on detail across interviews, no more than 10% of the variance in overall accuracy rate was explained by any individual measure. Number of contradictions and overall agreement between interviews did, however, make additive contributions to prediction of overall accuracy. Also, higher correlations between contradiction‐based consistency measures and interview two accuracy rate were detected. Neither consistency nor accuracy for specific testimonial dimensions were predictive of accuracy on the other dimensions, or overall accuracy. Copyright © 1999 John Wiley & Sons, Ltd.     

Developmental differences in the effects of repeated interviews and interviewer bias on young children's event memory and false reports

The present study investigated developmental differences in the effects of repeated interviews and interviewer bias on children's memory and suggestibility. Three- and 5-year-olds were singly or repeatedly interviewed about a play event by a highly biased or control interviewer. Children interviewed once by the biased interviewer after a long delay made the most errors. Children interviewed repeatedly, regardless of interviewer bias, were more accurate and less likely to falsely claim that they played with a man. In free recall, among children questioned once after a long delay by the biased interviewer, 5-year-olds were more likely than were 3-year-olds to claim falsely that they played with a man. However, in response to direct questions, 3-year-olds were more easily manipulated into implying that they played with him. Findings suggest that interviewer bias is particularly problematic when children's memory has weakened. In contrast, repeated interviews that occur a short time after a to-be-remembered event do not necessarily increase children's errors, even when interviews include misleading questions and interviewer bias. Implications for developmental differences in memory and suggestibility are discussed.     

Assessing the Truthfulness of Witness Statements Made by Children (Aged 7--8, 10--11, and 13--14) Employing Scales Derived from Johnson and Raye's Model of Reality Monitoring

The goal of this study was to determine whether children's true and false witness statements could be differentiated using the model of reality monitoring. The effects of age and verbal ability on scales based on the model were also investigated. Children (N = 68) from three different age-groups (7--8, 10--11, and 13--14 years) made both a true and a false statement concerning a mildly traumatic event. The statements were analysed using the Revised Memory Characteristics Questionnaire. The vocabulary sub-scale of the WISC-R was also administered. True statements were found to contain more sensory information and expressions of time, and less affective information. Overall, 64% of the statements were correctly classified on the basis of the scales. Older children received higher scores on most of the reality monitoring scales compared to the youngest children regardless of the truthfulness of their statements. Furthermore, the verbal ability of the children was positively associated with scores on several of the scales. The classification accuracy suggests that the model should not be applied to individual cases of child testimony. Although the final decision concerning the usefulness of the scales should be based on ecologically valid field studies.
