Credibility Assessment

Credibility assessment refers to any attempt to ascertain truthfulness. Other terms which have been used to refer to the assessment of credibility include the detection of deception and lie detection. The term lie detection has become virtually synonymous with the use of the polygraph and can no longer be used to refer to the range of procedures currently employed to assess credibility. Also, both lie detection and the detection of deception have a negative cast which does not fully capture the orientation of current approaches to credibility. Consequently, the term credibility assessment has emerged recently as the preferred label. The goal of credibility assessment is typically the determination of the truth of a statement or be found in set of statements. The need or desire to make such an assessment can every human context from marital relations through clinical examinations to police and court interrogations. Examples of the kinds of statements which require credibility assessment are: 1) A child's assertion that she or he has been sexually abused. 2) The claim by a previously suicidal person that he or she has recovered and will not attempt suicide again. 3) The denial of guilt by a suspect in a criminal investigation. 4 ) The confident statement of a witness that he or she is sure in his or her identification of a thief. 5) The vow of loyalty by a potential employee for a security job. It is necessary to assess the credibility of these and similar statements.

In 2001, the late Murray Kleiner and an array of experts contributed to the Handbook of Polygraph Testing, published by Elsevier, which examined the fundamental principles behind polygraph tests and reviewed the key tests and methods used at that time. In the intervening thirteen years, the field has moved beyond traditional polygraph testing to include a host of biometrics and behavioral observations. The new title reflects the breadth of methods now used. Credibility Assessment builds on the content provided in the Kleiner volume, with revised polygraph testing chapters and chapters on newer methodologies, such as CNS, Ocular-motor, and behavioral measures. Deception detection is a major field of interest in criminal investigation and prosecution, national security screening, and screening at ports of entry. Many of these methods have a long history, e.g., polygraph examinations, and some rely on relatively new technologies, e.g., fMRI and Ocular-motor measurements. Others rely on behavioral observations of persons in less restricted settings, e.g., airport screening. The authors, all of whom are internationally-recognized experts associated with major universities in the United States, United Kingdom, and Europe, review and analyze various methods for the detection of deception, their current applications, and major issues and controversies surrounding their uses. This volume will be of great interest among forensic psychologists, psychophysiologists, polygraph examiners, law enforcement, courts, attorneys, and government agencies. Provides a comprehensive review of all aspects of methods for deception detection Includes methods being used in credibility, such as autonomic, CNS, fMRI, and Ocular-motor measures and behavioral and facial observation Edited by leaders in the field with over 25+ years of experience Discusses theory and application

Contingent on funding being available, a Festschrift will be held in honor of Dr. John Yuille’s career as a Forensic Psychologist. He has become one of the most visible and respected Canadian psychologists worldwide. In light of his upcoming retirement in December 2006, the Festschrift will recognize Dr. Yuille’s achievements in the areas of eyewitness memory research (i.e., pioneering a new research paradigm that grants better validity), investigative interviewing (i.e., the development and use of the Step Wise Interview Protocol), and credibility assessment (i.e., introducing Statement Validity Analysis to North America). New directions for future work will be explored at the workshop. The focus of this Festschrift will be three-fold: 1. International. Dr. Yuille’s work has influenced law enforcement practices and stimulated research in and outside of Canada. The international and multicultural aspects of the work that Dr. Yuille has inspired will be reflected and promoted by this workshop. 2. Interdisciplinary. Dr. Yuille is internationally known as an expert, consultant and trainer to law enforcement. As such, Dr. Yuille’s work has also influenced other disciplines, e.g., the law, social work, oral history. The participants of this Festschrift will gain insight into other professionals’ perspectives and foster potential collaborations on future projects. 3. Emphasis on applied research. A hallmark of Dr. Yuille’s research has been the application of field and archival methods, which made his work directly applicable to forensically relevant contexts. The potential future directions of applied forensic research will be discussed at this Festschrift. The importance of the subject at this time: - A lack of integrative models in the literatures of eyewitness memory and the assessment of truthfulness and deception. Presenters of the Festschrift have recently developed such models and will discuss them at the Festschrift. Publishing these models and their discussions will spark further research to validate or modify them. - New, pioneering field research based on such integrative models has recently been conducted. This book would be one of the first publications of the results.

The difficulties in determining the quality of information on the Internet--in particular, the implications of wide access and questionable credibility for youth and learning. Today we have access to an almost inconceivably vast amount of information, from sources that are increasingly portable, accessible, and interactive. The Internet and the explosion of digital media content have made more information available from more sources to more people than at any other time in human history. This brings an infinite number of opportunities for learning, social connection, and entertainment. But at the same time, the origin of information, its quality, and its veracity are often difficult to assess. This volume addresses the issue of credibility--the objective and subjective components that make information believable--in the contemporary media environment. The contributors look particularly at youth audiences and experiences, considering the implications of wide access and the questionable credibility of information for youth and learning. They discuss such topics as the credibility of health information online, how to teach credibility assessment, and public policy solutions. Much research has been done on credibility and new media, but little of it focuses on users younger than college students. Digital Media, Youth, and Credibility fills this gap in the literature.

This book establishes a measurement index to quantify China’s mass media public credibility, based on extensive research and the encapsulation of measurement theories and approaches related to media public credibility, as well as numerous empirical case studies from the international academic community over the past hundred years. The investigation into the current state of Chinese mass media public credibility and discussion on practical approaches to enhancing such public credibility is highly significant in the context of research on media public credibility. The book focuses on two fundamental issues: i) investigating the basic factors the Chinese audience values as the yardstick for media credibility, and ii) formulating a media public credibility measurement scale. Relying on data from investigations, the authors analyze the importance of various assessment benchmarks for measuring media public credibility and the characteristics of public credibility assessment. Lastly, a measurement scale is created by screening and analyzing measurement indices with statistical methods such as exploratory and authenticated factor analyses and credibility and validity testing, which is of high theoretical and practical scientific value.

This is the first study to contrast how adults make credibility assessments about children who experienced a suggestive interview, children who had been coached to lie, and children who were telling the truth. Nine preschool children were interviewed about an event involving a minor infraction. Three of the children reported the truth, four were coached to lie, and two children reported misinformation as the result of a suggestive interview. Eighty-seven college students watched videotaped interviews of these nine children and assessed their credibility. Children who had experienced a suggestive interview were rated as credible as those who were telling the truth. Children who had been coached to lie were rated as less credible than the two groups of children. The results suggest that misleading information gets incorporated into children's memory, thus arguing for a cognitive rather than social explanation of suggestibility. The implication for children's court testimony and jury decisions are discussed. (Abstract).
