"Intuitive" lie detection of children's deception by law enforcement officials and university students

Detecting the veracity of children's experiences through drawings

Research is lacking regarding adults' ability to determine whether children's drawings are based on an experience or not. Drawings are useful in professional settings to alleviate linguistic demands, facilitate memory, and have been used as evidence. Determining the accuracy of veracity assessments of children's drawings would inform professionals regarding their use as evidence of experiences. Twenty-eight children (14 younger, Mage = 7.53 years, SDage = 1.19; 14 older, Mage = 11.67 years, SD = 1.27) produced drawings of two events: one staged experienced, and one narrative-based not experienced event. Fifty (Study 1, Mage = 23.72 years, SDage = 9.70) and 63 (Study 2, Mage = 25.92, SDage = 12.79) adults indicated whether each drawing was based on experience and their confidence in each assessment. In Study 2, additional drawing quality assessments were collected. Results indicated that adults were more accurate at distinguishing experienced than not experienced drawings for older artists. An inverse relationship was observed between confidence and accuracy-participants were more confident when they were inaccurate, especially for younger artists. Drawing quality improved with age and for drawings of experienced events. Adults tended to rate drawings of higher quality as resulting from experience leading to the highest accuracy for drawings from older artists that were based on experience. Overall, results suggest that there may be some features of drawings that allow for above chance levels of accuracy (up to 75%). However, rates are not high enough across assessments (M = 53.93%, range: 39%-75%) to reliably use them as indicators of experience.

Discernment of Children's True and False Memory Reports: Police Officers and Laypersons

Adults' ability to accurately evaluate children's statements can have far-reaching consequences within the legal system. This study examined the evaluations of police officers ("experts") and laypersons ("nonexperts") when presented with videotaped interviews of children aged 3 and 5 years who provided either true or false reports or denials. Participants were drawn from several counties in the eastern United States. Children's interview statements fell within four statement types: accurate reports, false reports, accurate denials, and false denials. Both groups of participants displayed overbelief in false denials. Several control variables predicted accuracy, including children's age and children's race. A significant interaction emerged: Experts (vs. nonexperts) had greater odds of being accurate when judging false reports (vs. false denials). These findings highlight the challenges adults face when distinguishing between various types of children's statements. The results have important implications for legal contexts, emphasizing that fact finders need to be mindful of the risks associated with both overaccepting false denials and accepting false reports.

First Approach to Abused Children by Health and Educational Professionals

Abstract. The present review aims to address child abuse, a phenomenon to which society has become more aware and directed more efforts, and the role that health and education professionals can play in its prevention and intervention. Based on the premise that professionals with a primary role of working with children, who may have the first contact with them after a situation of abuse, are mostly in the fields of health and education, it is important to reflect on their practices in these cases, which have particular relevance in order to avoid potential situations of secondary victimization, contamination of speech, or even withdrawal of revelation. This review examines the preparation of these professionals to address the allegedly abused child and to report abuse if they feel fit to take appropriate action, focuses mainly on the context of Portugal. What the literature shows is that there are still difficulties in making decisions and taking action in situations where abuse is suspected, based on physical or behavioral evidence from the child, or before his/her disclosure. Further studies are needed on the knowledge of the actions to be taken, and on the actions taken before there is a referral to the competent entities by these professionals. Moreover, there is a discussion on the need to develop training as well as brief and structured protocols for action, in this first line of intervention, when facing potential situations of child abuse.

Applying Hierarchy of Expert Performance (HEP) to investigative interview evaluation: strengths, challenges and future directions

The purpose of this paper is to systematically examine the research literature on the decision of expert interviewers within the theoretical framework of the Hierarchy of Expert Performance (HEP). After providing an overview of the HEP framework, existing research in the investigative interviewing at each of the eight levels of the HEP framework is reviewed. The results identify areas of strength in reliability between experts' observations (Level 2) and of weakness in reliability between experts' conclusions (Level 6). Biases in investigative interview experts' decision making is also revealed at biasability between expert conclusions (Level 8). Moreover, no published data are available in reliability within experts at the level of observations (Level 1) or conclusions (Level 5), biasability within or between expert observations (Level 3 and 4) and biasability within expert conclusions (Level 7). The findings highlight areas where future research and practical endeavour are much needed for the investigative interview.

Identifying Liars Through Automatic Decoding of Children's Facial Expressions

This study explored whether children's (N = 158; 4- to 9 years old) nonverbal facial expressions can be used to identify when children are being deceptive. Using a computer vision program to automatically decode children's facial expressions according to the Facial Action Coding System, this study employed machine learning to determine whether facial expressions can be used to discriminate between children who concealed breaking a toy(liars) and those who did not break a toy(nonliars). Results found that, regardless of age or history of maltreatment, children's facial expressions could accurately (73%) be distinguished between liars and nonliars. Two emotions, surprise and fear, were more strongly expressed by liars than nonliars. These findings provide evidence to support the use of automatically coded facial expressions to detect children's deception.

The effects of the putative confession and evidence presentation on maltreated and non-maltreated 9- to 12-year-olds' disclosures of a minor transgression

The current study examined the influence of the putative confession (in which children are told that the suspect told them "everything that happened" and "wants [the child] to tell the truth") and evidence presentation on 9- to 12-year-old maltreated and non-maltreated children's disclosure (N = 321). Half of the children played a forbidden game with an adult confederate that resulted in a laptop computer breaking (no transgression occurred for the other half of the children), followed by coaching to conceal the forbidden game and to falsely disclose the sanctioned game. Children were then interviewed about the interaction with the confederate. Among the 9- and 10-year-olds, the putative confession led to a higher rate of breakage disclosure (62%) than the control condition (13%) and to a higher rate of leakage of incriminating details during recall (47% vs. 9%). Older children were more likely to disclose than younger children and to be uninfluenced by the putative confession. Among all ages, evidence presentation elicited disclosures from 63% of children who had not previously disclosed without eliciting any false disclosures.

Effects of the putative confession instruction on perceptions of children's true and false statements

The putative confession (PC) instruction (i.e., "[suspect] told me everything that happened and wants you to tell the truth") during forensic interviews with children has been shown to increase the accuracy of children's statements, but it is unclear whether adults' perceptions are sensitive to this salutary effect. The present study examined how adults perceive children's true and false responses to the PC instruction. Participants (n = 299) watched videotaped interviews of children and rated the child's credibility and the truthfulness of his/her statements. When viewing children's responses to the PC instruction, true and false statements were rated as equally credible, and there was a decrease in accuracy for identifying false denials as lies. These findings suggest that participants viewed the PC instruction as truth-inducing. Implications for the forensic use of the PC instruction are discussed.

When Is a Child's Forensic Statement Deemed Credible? A Comparison of Physical and Sexual Abuse Cases

A large national sample of 4,775 reports of child physical and sexual abuse made in Israel in 2014 was analyzed in order to examine whether assessments of credibility would vary according to abuse type, physical or sexual, and whether child and event characteristics contributing to the probability that reports of abuse would be determined as credible would be similar or different in child physical abuse (CPA) and child sexual abuse (CSA) cases. Results revealed that CPA reports were less likely to be viewed as credible (41.9%) compared to CSA reports (56.7%). Multigroup path analysis, however, indicated equivalence in predicting factors. In a unified model for both types of abuse, salient predictors of a credible judgment were older age, lack of a cognitive delay, and the alleged abusive event being a onetime less severe act. Over and beyond the effects of these factors, abuse type significantly contributed to the prediction of credibility judgments.

Does parental coaching affect children's false reports? Comparing verbal markers of deception

The present study examined differences in children's true and false narratives as a function of parental coaching by comparing the verbal markers associated with deception. Children (N = 65, 4-7 years old) played the same game with an adult stranger over three consecutive days. Parents coached their children to falsely allege that they had played a second game and to generate details for the fabricated event. One week after the last play session, children were interviewed about their experiences. For children with the least amount of parental coaching, true and false reports could be distinguished by multiple verbal markers of deception (e.g., cognitive processes, temporal information, self-references). The fabricated reports of children who spent more time being coaching by a parent resembled their truthful reports. These findings have implications for real-world forensic contexts when children have been coached to make false allegations and fabricate information at the behest of a parent.

Credibility assessment in child sexual abuse investigations: A descriptive analysis

A major challenge in cases of child sexual abuse (CSA) is determining the credibility of children's reports. Consequently cases may be misclassified as false or deemed 'no judgment possible'. Based on a large national sample of reports of CSA made in Israel in 2014, the study examines child and event characteristics contributing to the probability that reports of abuse would be judged credible. National data files of all children aged 3-14, who were referred for investigation following suspected victimization of sexual abuse, and had disclosed sexual abuse, were analyzed. Cases were classified as either 'credible' or 'no judgment possible'. The probability of reaching a 'credible' judgment was examined in relation to characteristics of the child (age, gender, cognitive delay, marital status of the parents,) and of the abusive event (abuse severity, frequency, perpetrator-victim relationship, perpetrator's use of grooming, and perpetrator's use of coercion), controlling for investigator's identity at the cluster level of the analysis. Of 1563 cases analyzed, 57.9% were assessed as credible. The most powerful predictors of a credible judgment were older age and absence of a cognitive delay. Reports of children to married parents, who experienced a single abusive event that involved perpetrator's use of grooming, were also more likely to be judged as credible. Rates of credible judgments found are lower than expected suggesting under-identification of truthful reports of CSA. In particular, those cases of severe and multiple abuse involving younger and cognitively delayed children are the ones with the lowest chances of being assessed as credible.

The Child Witness in the Courtroom

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.

High Cognitive Load During Cross-Examination: Does It Improve Detection of Children's Truths and Lies?

The current study used a high cognitive load cross-examination procedure to determine whether this would improve undergraduate students' ability to detect deception in children aged 9 to 12 years. The participants (n = 88) were asked to determine whether children's accounts of an event included a true denial, false denial, true assertion or false assertion about a game played during a home visit occurring one week prior. Overall, the high cognitive load cross-examination did not improve detection rates, in that participants were at chance level for both direct examination (49.4%) and cross-examination (52.3%). Accuracy for true stories was greater than for false stories. Cross-examination improved the detection rates of the false stories, but worsened the accuracy for the true stories. The participants did however rate younger children's true reports to be more credible and believable than their false reports. Participants rated older children's false reports as more credible and believable than their true reports.

White lie-telling in children for politeness purposes

Prosocial lie-telling behavior in children between 3 and 11 years of age was examined using an undesirable gift paradigm. In the first condition, children received an undesirable gift and were questioned by the gift-giver about whether they liked the gift. In the second condition, children were also given an undesirable gift but received parental encouragement to tell a white lie prior to being questioned by the gift-giver. In the third condition, the child's parent received an undesirable gift and the child was encouraged to lie on behalf of their parent. In all conditions, the majority of children told a white lie and this tendency increased with age. Coding of children's facial expressions using Ekman and Friesen's (1978) Facial Action Coding System revealed significant but small differences between lie-tellers and control children in terms of both positive and negative facial expressions. Detailed parental instruction facilitated children's display of appropriate verbal and nonverbal expressive behaviors when they received an undesirable gift.

Deceit and facial expression in children: the enabling role of the "poker face" child and the dependent personality of the detector

This study presents the relation between the facial expression of a group of children when they told a lie and the accuracy in detecting the lie by a sample of adults. To evaluate the intensity and type of emotional content of the children's faces, we applied an automated method capable of analyzing the facial information from the video recordings (FaceReader 5.0 software). The program classified videos as showing a neutral facial expression or an emotional one. There was a significant higher mean of hits for the emotional than for the neutral videos, and a significant negative correlation between the intensity of the neutral expression and the number of hits from the detectors. The lies expressed with emotional facial expression were more easily recognized by adults than the lies expressed with a "poker face"; thus, the less expressive the child the harder it was to guess. The accuracy of the lie detectors was then correlated with their subclinical traits of personality disorders, to find that participants scoring higher in the dependent personality were significantly better lie detectors. A non-significant tendency for women to discriminate better was also found, whereas men tended to be more suspicious than women when judging the children's veracity. This study is the first to automatically decode the facial information of the lying child and relate these results with personality characteristics of the lie detectors in the context of deceptive behavior research. Implications for forensic psychology were suggested: to explore whether the induction of an emotion in a child during an interview could be useful to evaluate the testimony during legal trials.

Can classic moral stories promote honesty in children?

The classic moral stories have been used extensively to teach children about the consequences of lying and the virtue of honesty. Despite their widespread use, there is no evidence whether these stories actually promote honesty in children. This study compared the effectiveness of four classic moral stories in promoting honesty in 3- to 7-year-olds. Surprisingly, the stories of "Pinocchio" and "The Boy Who Cried Wolf" failed to reduce lying in children. In contrast, the apocryphal story of "George Washington and the Cherry Tree" significantly increased truth telling. Further results suggest that the reason for the difference in honesty-promoting effectiveness between the "George Washington" story and the other stories was that the former emphasizes the positive consequences of honesty, whereas the latter focus on the negative consequences of dishonesty. When the "George Washington" story was altered to focus on the negative consequences of dishonesty, it too failed to promote honesty in children.

Deception detection, transmission, and modality in age and sex

This study is the first to create and use spontaneous (i.e., unrehearsed) pro-social lies in an ecological setting. Creation of the stimuli involved 51 older adult and 44 college student “senders” who lied “authentically” in that their lies were spontaneous in the service of protecting a research assistant. In the main study, 77 older adult and 84 college raters attempted to detect lies in the older adult and college senders in three modalities: audio, visual, and audiovisual. Raters of both age groups were best at detecting lies in the audiovisual and worst in the visual modalities. Overall, college students were better detectors than older adults. There was an age-matching effect for college students but not for older adults. Older adult males were the hardest to detect. The older the adult was the worse the ability to detect deception.

How Children Report True and Fabricated Stressful and Non-Stressful Events

As children can be victims or witnesses to crimes and may be required to testify about their experiences in court, the ability to differentiate between children's true and fabricated accounts of victimization is an important issue. This study used automated linguistic analysis software to detect linguistic patterns in order to differentiate between children's true and false stressful bullying reports and reports of non-stressful events. Results revealed that children displayed different linguistic patterns when reporting true and false stressful and non-stressful stories, with non-stressful stories being more accurately discriminated based on linguistic patterns. Results suggest that it is difficult to discriminate accurately and consistently between children's true and false stories of victimization.

Little Liars: Development of Verbal Deception in Children

Lying is common among adults and a more complex issue in children. In this article, I review two decades of empirical evidence about lying in children from the perspective of speech act theory. Children begin to tell lies in the preschool years for anti- and prosocial purposes, and their tendency to lie changes as a function of age and the type of lies being told. In addition, children's ability to tell convincing lies improves with age. In the article, I highlight the central roles that children's understanding of mental states and social conventions play in the development of lying. I also identify areas for research to be done to develop a more comprehensive picture of the typical and atypical developmental courses of verbal deception in children.

"That never happened": adults' discernment of children's true and false memory reports

Adults' evaluations of children's reports can determine whether legal proceedings are undertaken and whether they ultimately lead to justice. The current study involved 92 undergraduates and 35 laypersons who viewed and evaluated videotaped interviews of 3- and 5-year-olds providing true or false memory reports. The children's reports fell into the following categories based on a 2 (event type: true vs. false) × 2 (child report: assent vs. denial) factorial design: accurate reports, false reports, accurate denials, and false denials. Results revealed that adults were generally better able to correctly judge accurate reports, accurate denials, and false reports compared with false denials: For false denials, adults were, on average, "confident" that the event had not occurred, even though the event had in fact been experienced. Participant age predicted performance. These findings underscore the greater difficulty adults have in evaluating young children's false denials compared with other types of reports. Implications for law-related situations in which adults are called upon to evaluate children's statements are discussed.

The Effects of Repetition on Children's True and False Reports

As children are often called upon to provide testimony in court proceedings, determining the veracity of their statements is an important issue. In the course of investigation by police and social workers, children are often repeatedly interviewed about their experiences, though the impact of this repetition on children's true and false statements remains largely unexamined. The current study analysed semantic differences in children's truthful and fabricated statements about an event they had or had not participated in. Results revealed that children's truthful and fabricated reports differed in linguistic content, and that their language also varied with repetition. Discriminant analyses revealed that with repetition, children's true and false reports became increasingly difficult to differentiate using linguistic markers, though true reports were consistently classified correctly at higher rates than false reports. The implications of these findings for legal procedures concerning child witnesses are discussed.

Detecting children's lies: comparing true accounts about highly stressful injuries with unprepared, prepared, and coached lies

In this investigation, 514 university students judged whether children were telling the truth about highly emotional events. Eight children (half female, half 8-9 and the remainder 12-14 years old) had been injured seriously enough to require emergency room treatment and were interviewed a few days later. Each was yoked to three other children matched in age and gender who fabricated accounts under one of three conditions: lies that were unprepared, prepared (24 hours to prepare), and coached by parents. Participants were at chance when judging true accounts as well as unprepared and prepared lies. However, 74% of the coached lies were judged as true. Participants' confidence in their judgments, age, experience with children, and relevant coursework/training did not improve judgments.

The reliability of lie detection performance

We examined whether individuals' ability to detect deception remained stable over time. In two sessions, held one week apart, university students viewed video clips of individuals and attempted to differentiate between the lie-tellers and truth-tellers. Overall, participants had difficulty detecting all types of deception. When viewing children answering yes-no questions about a transgression (Experiments 1 and 5), participants' performance was highly reliable. However, rating adults who provided truthful or fabricated accounts did not produce a significant alternate forms correlation (Experiment 2). This lack of reliability was not due to the types of deceivers (i.e., children versus adults) or interviews (i.e., closed-ended questions versus extended accounts) (Experiment 3). Finally, the type of deceptive scenario (naturalistic vs. experimentally-manipulated) could not account for differences in reliability (Experiment 4). Theoretical and legal implications are discussed.

Children's knowledge of deceptive gaze cues and its relation to their actual lying behavior

Eye gaze plays a pivotal role during communication. When interacting deceptively, it is commonly believed that the deceiver will break eye contact and look downward. We examined whether children's gaze behavior when lying is consistent with this belief. In our study, 7- to 15-year-olds and adults answered questions truthfully (Truth questions) or untruthfully (Lie questions) or answered questions that required thinking (Think questions). Younger participants (7- and 9-year-olds) broke eye contact significantly more when lying compared with other conditions. Also, their averted gaze when lying differed significantly from their gaze display in other conditions. In contrast, older participants did not differ in their durations of eye contact or averted gaze across conditions. Participants' knowledge about eye gaze and deception increased with age. This knowledge significantly predicted their actual gaze behavior when lying. These findings suggest that with increased age, participants became increasingly sophisticated in their use of display rule knowledge to conceal their deception.

Adults' judgments of children's coached reports

This study investigated adults' judgments of the honesty of children's coached true and fabricated mock testimony. Adults saw video clips of children testifying in a mock court about a true or fabricated event in their lives. They were asked to make an assessment of the truthfulness of the testimony, and respond to questions about their perception of children's credibility. Half of the adults saw children testifying after a competence examination, and the other half saw children testifying without a competence examination. Overall, girls were rated as more competent than boys, and their testimony was more likely to be believed. Younger children were more likely to be rated as incompetent than older children. A factor analysis of adults' responses revealed six factors which significantly predicted adults' overall assessment of children's credibility, and their evaluations of children's competence to testify. Adults' detection accuracy was at chance, with the majority of children rated as truthful. Viewing the competency examination and cross-examination did not improve the adults' detection accuracy. However, seeing the cross-examination made adults' less likely to believe children's testimony. The implications of these results for the judicial system are discussed.

Adults' judgments of children's coached reports

This study investigated adults' judgments of the honesty of children's coached true and fabricated mock testimony. Adults saw video clips of children testifying in a mock court about a true or fabricated event in their lives. They were asked to make an assessment of the truthfulness of the testimony, and respond to questions about their perception of children's credibility. Half of the adults saw children testifying after a competence examination, and the other half saw children testifying without a competence examination. Overall, girls were rated as more competent than boys, and their testimony was more likely to be believed. Younger children were more likely to be rated as incompetent than older children. A factor analysis of adults' responses revealed six factors which significantly predicted adults' overall assessment of children's credibility, and their evaluations of children's competence to testify. Adults' detection accuracy was at chance, with the majority of children rated as truthful. Viewing the competency examination and cross-examination did not improve the adults' detection accuracy. However, seeing the cross-examination made adults' less likely to believe children's testimony. The implications of these results for the judicial system are discussed.

Hearsay versus children's testimony: Effects of truthful and deceptive statements on jurors' decisions

Researchers and courts are focusing increasing attention on the reliability of children's out-of-court statements, especially in relation to trials of child sexual abuse. The main goal of this study was to investigate the effects of presentation of children's out-of-court statements (e.g., hearsay) on jurors' perceptions of witness credibility and defendant guilt, and on jurors' abilities to reach the truth. Child participants experienced either a mock crime or were coached to say they experienced the crime when in fact they had not. During elaborate mock trials involving community member jurors, children's testimony was presented either: (1) live, (2) on videotape, or (3) via a social worker. Analyses revealed that testimony format directly influenced jurors' perceptions of child and social worker credibility (e.g., children were perceived as less likely to provide false statements if they testified live) as well as jurors' sympathy toward the child, all of which then predicted jurors' confidence in defendant guilt. Jurors had difficulty discerning accurate from deceptive child statements regardless of testimony format. Implications for psychology and the legal system are discussed.

Adults' ability to detect children's lying

Adults are poor deception detectors when examining lies told by adults, on average. However, there are some adults who are better at detecting lies than others. Children learn to lie at a very young age, a behavior that is socialized by parents. Yet, less is known about the ability to detect children's lies, particularly with regard to individual differences in the ability to detect this deception. The current study explored adult raters' ability to discern honesty in children who lied or told the truth about committing a misdeed. Results showed that adults are no better at detecting children's lies than they are with adult lies. In particular, adults were very poor at identifying children's honest statements. However, individual differences did emerge, suggesting that the ability to detect lying in children might be facilitated by relevant experience working with children. Implications for legal and mental health contexts are discussed.

The Psychology of Confessions: A Review of the Literature and Issues

Recently, in a number of high-profile cases, defendants who were prosecuted, convicted, and sentenced on the basis of false confessions have been exonerated through DNA evidence. As a historical matter, confession has played a prominent role in religion, in psychotherapy, and in criminal law-where it is a prosecutor's most potent weapon. In recent years, psychologists from the clinical, personality, developmental, cognitive, and social areas have brought their theories and research methods to bear on an analysis of confession evidence, how it is obtained, and what impact it has on judges, juries, and other people. Drawing on individual case studies, archival reports, correlational studies, and laboratory and field experiments, this monograph scrutinizes a sequence of events during which confessions may be obtained from criminal suspects and used as evidence. First, we examine the preinterrogation interview, a process by which police target potential suspects for interrogation by making demeanor-based judgments of whether they are being truthful. Consistent with the literature showing that people are poor lie detectors, research suggests that trained and experienced police investigators are prone to see deception at this stage and to make false-positive errors, disbelieving people who are innocent, with a great deal of confidence. Second, we examine the Miranda warning and waiver, a process by which police apprise suspects of their constitutional rights to silence and to counsel. This important procedural safeguard is in place to protect the accused, but researchers have identified reasons why it may have little impact. One reason is that some suspects do not have the capacity to understand and apply these rights. Another is that police have developed methods of obtaining waivers. Indeed, innocent people in particular tend to waive their rights, naively believing that they have nothing to fear or hide and that their innocence will set them free. Third, we examine the modern police interrogation, a guilt-presumptive process of social influence during which trained police use strong, psychologically oriented techniques involving isolation, confrontation, and minimization of blame to elicit confessions. Fourth, we examine the confession itself, discussing theoretical perspectives and research on why people confess during interrogation. In particular, we focus on the problem of false confessions and their corrupting influence in cases of wrongful convictions. We distinguish among voluntary, compliant, and internalized false confessions. We describe personal risk factors for susceptibility to false confessions, such as dispositional tendencies toward compliance and suggestibility, youth, mental retardation, and psychopathology. We then examine situational factors related to the processes of interrogation and show that three common interrogation tactics-isolation; the presentation of false incriminating evidence; and minimization, which implies leniency will follow-can substantially increase the risk that ordinary people will confess to crimes they did not commit, sometimes internalizing the belief in their own culpability. Fifth, we examine the consequences of confession evidence as evaluated by police and prosecutors, followed by judges and juries in court. Research shows that confession evidence is inherently prejudicial, that juries are influenced by confessions despite evidence of coercion and despite a lack of corroboration, and that the assumption that "I'd know a false confession if I saw one" is an unsubstantiated myth. Finally, we address the role of psychologists as expert witnesses and suggest a number of possible safeguards. In particular, we argue that there is a need to reform interrogation practices that increase the risk of false confessions and recommend a policy of mandatory videotaping of all interviews and interrogations.
