Summary Since the Cognitive Interview (CI) was developed, many experiments have been published, but only two investigated its efficacy in real criminal cases. Here, a Modified CI (MCI) is tested with interviews an inquisitor justice system. Several moderators and interviewers' attitudes towards CI/MCI are also examined. Eighty‐one witnesses were interviewed by 27 French military police officers, Standard Police Interview, Structured (SI), or MCI. The MCI produced most forensically relevant...

In this article, we wish to foster a dialogue between theory-based and classification-oriented stylometric approaches regarding deception detection. To do so, review how cue-based model-based systems are used detect deceit. Baseline methods, common cues, recent field studies presented. After reviewing computational tools have been for detection purposes, show that the he methods cannot be applied problems on in their current state. We then identify important advantages issues of tools....

Two studies explore the impact of body size on daily life activities women with obesity. In first study, ethnographic techniques (first-person perspective video recordings) and subsequent interviews based recordings were used. Results showed atypical behavior obesity ex-obese related to memories embarrassing experiences regarding personal (sitting, passing doors sideways, over-careful navigation in public space, choosing clothes sizes too large.) Women seem behave as if they thought had a...

Les partisans de la synergologie considèrent comme une discipline scientifique. Mais l’unique publication révisée par les pairs (Turchet, 2013) comporte des lacunes (utilisation inadaptée littérature scientifique pour justifier arguments, biais méthodologiques). Par ailleurs, astuces rhétoriques sont utilisées afin présenter certains résultats validant hypothèses. Ainsi, n’a que l’apparence d’une et l’absence théories validations fiables classe inévitablement pseudo-science. Cette analyse...

There are two primary investigative interview objectives: gathering information to determine what happened and who did it assessing the witness's reliability. The present study examined extent interviewers gather investigation-relevant (IRI) compared interviewee details (ID) assess witness As part of a training course, 42 police officers participated as mock witnesses by viewing crime video. interviews were recorded rated for question type content through thematic analyses. IRI questions...

Abstract Recent research shows that the quality of a baseline (i.e., analysis one's behavior in normal conditions) decreases when second narrative is expected and deceitful. However, first step would be to investigate whether writing might influence second, independently its expectancy. In this study, we hypothesized narratives less detailed, especially if these are deceptive. Participants (N = 71) were asked narrate two consecutive truthful deceptive narratives. The was unexpected, order...

Summary Information manipulation and cognitive load imposition make the production of deceptive narratives difficult. But little is known about deception, how its mechanisms may help distinguish truthful from deceitful narratives. This study focuses on measurement keystroke dynamics while typing eyewitness testimonies after a baseline assessment. While their narrative, some participants would undergo an auditory load. Results show that liars typed story slower, in less time than when...

Neuropsychology of artificial intelligence focuses on synthetic neural cog nition as a new type study object within cognitive psychology. With the goal making networks language models more explainable, this approach involves transposing concepts from psychology to interpretive construction cognition. The human concept involved here is categorization, serving heuristic for thinking about process segmentation and reality carried out by vectors

We propose a neuropsychological approach to the explainability of artificial neural networks, which involves using concepts from human cognitive psychology as relevant heuristic references for developing synthetic explanatory frameworks that align with modes thought. The analogical mobilized here, are intended create such an epistemological bridge, those categorization and similarity, these notions particularly suited categorical "nature" reconstructive information processing performed by...
