  • L’analyse de la communication non verbale: Les dangers de la pseudoscience en contextes de sécurité et de justice
  • 2020

    • For security and justice professionals, the thousands of peer-reviewed articles on nonverbal communication represent important sources of knowledge. However, despite the scope of the scientific work carried out on this subject, professionals can turn to programs, methods and approaches that fail to reflect the state of science. The objective of this article is to examine (i) concepts of nonverbal communication conveyed by these programs, methods and approaches, but also (ii) the consequences of their use. To achieve this objective, we describe the scope of scientific research on nonverbal communication. A program (SPOT; “Screening of Passengers by Observation Techniques”), a method (the BAI; “Behavior Analysis Interview”) and an approach (synergology) that each run counter to the state of science are examined. Finally, we outline five hypotheses to explain why some organizations in the fields of security and justice are turning to pseudoscience and pseudoscientific techniques. © 2020, Polymedia Meichtry SA.

  • Establishing Origin: Analysing the Questions Asked in Asylum Interviews
  • 2018
  • Ingår i: Psychiatry Psychology and Law. - : Informa UK Limited. - 1321-8719 .- 1934-1687. ; 25:2, s. 283-302

    • In the absence of evidence, asylum seekers are interviewed to assess the credibility of their stories. Few studies have examined whether or not the questions asked in such interviews stimulate the applicant to give lengthy, detailed, and accurate answers. The style, type, and content of the questions asked in order to assess a claim about origin were analysed in 40 case files from the Dutch Immigration Service. A large proportion of the questions were closed and fact-checking questions. Less than one fifth of questions were open or cued recall questions. The results show that to assess credibility of origin, knowledge questions were posed about the immediate living environment, flight to Europe, identity documents, country of origin, and personal background of applicants. Possibilities for increasing the quantity and quality of information obtained in asylum interviews are discussed. Future research should validate the assumption that truthful claimants have substantial knowledge about their country and town of origin.

  • Memory of Uncooperative Witnesses
  • 2017
  • Ingår i: Pitch presentation during the 2017 conference of the European Association of Psychology and Law in Mechelen, Belgium.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction Despite the importance of their testimony, witnesses rarely provide sufficient information (Kebbell & Milne, 1998). However, witnesses’ reports are not necessarily a representation of memory. In fact, lack of reporting does not equal to lack of memory. But, there is no empirical evidence on whether memory is protected if it is not reported. This will be the first study to examine whether level of cooperation during an investigative interview affects memory for the target event. Specifically, we aim to learn whether memory traces are conserved when witnesses are uncooperative. Method During an in-person session, all participants will watch a mock-crime video clip and serve as eyewitnesses. They will be randomly assigned to only one of four interviewing conditions: control, enhanced cooperative style and two uncooperative style groups. Participants in the uncooperative groups will be told that the police believe they also participated in the crime. It is expected that participants to avoid self-incrimination will be less cooperative than those who are independent witnesses. Further, those in the enhanced cooperative condition will receive an extra incentive to facilitate disclosure. After a week, only one of the uncooperative groups will be debriefed. All groups will be interviewed again. Memory performance will be measured in both interviews. Results A literature review regarding memory for the unsaid (i.e., what is remembered and not disclosed) shows mixed results. Lack of disclosure of information can be accompanied, or not, by remembering. Thus, not reporting may lead to forgetting, but also to memory facilitation (Stone, Coman, Brown, Koppel & Hirst, 2012). As this is an exploratory study, no directional hypotheses are formulated. Preliminary data will be presented during the conference. Discussion Learning about how interview cooperation style affects memory and how this can be best recalled at a later stage is of particular relevance.

  • Uncooperative Witnesses and their Inclination to Disclose Information
  • 2018
  • Ingår i: European Association of Psychology and Law (EAPL) Conference. Turku, Finland: 26-29 June 2018.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Objectives Police rely on witness testimony to advance criminal investigations; however, witnesses do not always cooperate. Despite the importance of witness cooperation for gathering information during investigative interviews, it has received little scrutiny. We examined the extent to which witness cooperation affects information disclosure, and how lack of cooperation affects the reliability of witness testimony. Method Participants (N=139) watched a mock-crime video and were interviewed twice over a two-week period. They were randomly assigned to one of four experimental conditions: control, cooperative and two uncooperative groups. In the cooperative group, participants were informed they were key witnesses, whereas those in the control condition did not receive especial instructions. Participants in the uncooperative groups were told the police believed they participated in the crime, but before the second interview one of the uncooperative groups was informed they were not longer incriminated. The amount of information disclosed was measured in both interviews. Results Data is currently being analysed and will be presented at the conference. We predict that witness cooperation level will affect information disclosure during investigative interviews. Specifically, uncooperative interviewees will disclose less detailed information, and will omit crime relevant facts, compared to those in the cooperative and control conditions. Additionally, we will examine whether memory for initially unreported information is impaired by an initial uncooperative interview. Conclusion Understanding how witness cooperation affects information gathering during investigative interviews is relevant to examine the reliability of testimonies from uncooperative witnesses, and to inform interviewing practice that promotes cooperative reporting and facilitates disclosure.

  • What if Witnesses are Uncooperative? – A Glimpse on Current Interviewing Practice in The Netherlands.
  • 2018
  • Ingår i: 11th Annual Conference & Masterclas of the International Investigative Interviewing Research Group (iIIRG). Porto, Portugal: July 2018.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Objectives Research has informed best practice guidelines to interview witnesses however, their efficacy and application are highly dependent on the level of cooperation from the interviewee, questioning their suitability when witnesses do not cooperate. Despite its importance, how to best interview uncooperative witnesses has received little attention. We aimed to obtain an insight into current interviewing practice when conducting investigative interviews with uncooperative witnesses. Method Semi-structured interviews were conducted with ten police officers working as interviewers, interviewing instructors, and researchers. Transcribed interviews were analysed following a thematic analysis. Results Witness cooperation had a significant impact on interviewing style. Officers identified the lack of a specific interviewing protocol and training to gain witness cooperation challenging. This leads to intuitive interviewing, and great variance in preferred interviewing strategies and question type. While some focus on building rapport and facilitate witness protection to promote disclosure, others focus on confronting witnesses with the legal consequences of lack of cooperation and making moral appeals to overcome witness resistance. Conclusion Witnesses’ unwillingness to disclose information during investigative interviews can hinder criminal investigations. Understanding how uncooperative witnesses are interviewed informs how to improve interviewing practice that promotes cooperative reporting and facilitate eliciting complete and accurate witness accounts.

  • Accountability in legal decision-making
  • 2022
  • Ingår i: Psychiatry, Psychology and Law. - : Informa UK Limited. - 1321-8719 .- 1934-1687. ; 29:3
  • Tidskriftsartikel (refereegranskat)abstract
    • Having to explain a decision has often been found to have a positive effect on the quality of a decision. We aimed to determine whether different accountability requirements for judges (i.e., having to justify their decision or having to explicate their decision) affect evidence use. Those requirements were compared to instructions based on the falsification principle and a control condition. Participants (N = 173) decided on the defendant’s guilt in a murder case vignette and explained their decision according to the instructions. The explication and falsification (but not the justification) instructions increased the use of exonerating evidence. There was no significant difference between the groups in guilt perception. The use of exonerating evidence was a significant positive predictor of acquittal rates. The implications for the different forms of instructions in practice are positive, but suggest a difference between the evidence considered and the evidence used to account for the decision. © 2021 The Author(s).

  • Law and order effects: on cognitive dissonance and belief perseverance
  • 2022
  • Ingår i: Psychiatry Psychology and Law. - : Informa UK Limited. - 1321-8719 .- 1934-1687. ; 29:1, s. 33-52
  • Tidskriftsartikel (refereegranskat)abstract
    • Order of evidence presentation affects the evaluation and the integration of evidence in mock criminal cases. In this study, we aimed to determine whether the order in which incriminating and exonerating evidence is presented influences cognitive dissonance and subsequent display of confirmation bias. Law students (N = 407) were presented with a murder case vignette, followed by incriminating and exonerating evidence in various orders. Contrary to a predicted primacy effect (i.e. early evidence being most influential), a recency effect (i.e. late evidence being most influential) was observed in ratings of likelihood of the suspect's guilt. The cognitive dissonance ratings and conviction rates were not affected by the order of evidence presentation. The effects of evidence presentation order may be limited to specific aspects of legal decisions. However, there is a need to replicate the results using procedures and samples that are more representative of real-life criminal law trials.

  • Test of the analysis of competing hypotheses in legal decision-making
  • 2021
  • Ingår i: Applied Cognitive Psychology. - : Wiley. - 0888-4080 .- 1099-0720. ; 35:1, s. 62-70
  • Tidskriftsartikel (refereegranskat)abstract
    • The analysis of competing hypotheses (ACH) has been suggested to be a method that can protect against confirmation bias in the context of intelligence analysis. In the current study, we aimed to determine whether ACH could counter confirmation bias in the reasoning with evidence in the context of criminal law proceedings. Law students (N = 191) received information about the ACH method or general information about biases. They were given a case vignette with a main suspect and a list of 24 questions, 6 of which they could ask about the case. Half of the questions related to incriminating information, whereas the other half related to exonerating information. Contrary to our expectations, participants in both conditions favoured questions relating to exonerating information and rated the exonerating evidence as being more important for their decision. Despite the lack of bias observed, it seems participants failed to properly apply the ACH method.

  • Future directions in managing aniridia-associated keratopathy
  • 2023
  • Ingår i: Survey of ophthalmology. - : ELSEVIER SCIENCE INC. - 0039-6257 .- 1879-3304. ; 68:5, s. 940-956
  • Forskningsöversikt (refereegranskat)abstract
    • Congenital aniridia is a panocular disorder that is typically characterized by iris hypoplasia and aniridia-associated keratopathy (AAK). AAK results in the progressive loss of corneal transparency and thereby loss of vision. Currently, there is no approved therapy to delay or prevent its progression, and clinical management is challenging because of phenotypic variability and high risk of complications after interventions; however, new insights into the molecular pathogenesis of AAK may help improve its management. Here, we review the current understanding about the pathogenesis and management of AAK. We highlight the biological mechanisms involved in AAK development with the aim to develop future treatment options, including surgical, pharmacological, cell therapies, and gene therapies.
