Does the oath enhance truth-telling in eyewitness testimony? experimental evidence
Pour une science de la transition énergétique au service de la société. Rapport d’un groupe de travail interdisciplinaire de la cellule énergie du CNRS
La recherche sur la transition énergétique pose plusieurs défis de taille : c’est une recherche orientée problème (celui de la décarbonation du mix énergétique), qui doit être résolument éthique et intégrer dès sa formulation des principes de justice sociale et environnementale..., et ce alors même que la notion de transition est problématique en cela qu’elle donne l’impression que le processus qui mènera aux changements attendus – si changements…
Deception in Negotiations
Effect of a verbatim instruction on earwitness recall
When tasked with recalling a heard conversation, most individuals are unable to remember specific details. In this study, we tested the effect of Verbatim Recall Instruction (VRI) at recall. Drawing on fuzzy-trace theory, we hypothesised that the use of VRI would lead earwitnesses to use their verbatim mnesic trace to produce a more detailed recall. We compared the quantity and the quality of 42 recalls from participants who had received the VRI …

Spontaneous Comparison of Nanotechnology and Controversial Objects among Laypersons, Scientists and Environmentalists
Nanotechnologies are a controversial topic, as they seem promising but also cause concern. Previous research has highlighted the potential link between nanotechnologies and other hazardous technologies. The aim of this research was to analyse the discourse on this topic by three groups of participants: laypersons, scientists and environmentalists. Thirty-four people (13 laypersons, ten scientists and eleven environmentalists) were interviewed usi…
Social contact, own-group recognition bias and visual attention to faces
The own-group recognition bias (OGRB) has been consistently linked to social contact in theoretical accounts. Indeed, social contact is assumed by most authors to underlie the perceptual expertise of out-groups' faces. However, little is known empirically about how it might impact face-processing strategies. We tested the proposition that social interaction would improve the face recognition performance of another group by modulating visual strat…
Automatic recognition, elimination strategy and familiarity feeling
Beyond investigation-relevant information
There are two primary investigative interview objectives: gathering information to determine what happened and who did it and assessing the witness’s reliability. The present study examined to what extent investigative interviewers gather investigation-relevant information (IRI) compared to interviewee details (ID) to assess witness reliability. As part of a training course, 42 police officers participated as interviewers and mock witnesses by vi…
Is the social representation of nanotechnology anchored in that of GMOs
The use of nanotechnology (devices/materials composed of parts less than 10 nanometres) in the development of new products is rapidly expanding. Industrialists and decision-makers consider nanotechnology to be the next industrial revolution, but fear they risk the same resistance to nanotechnology that their counterparts experienced with genetically modified organisms (GMOs). Although risk perception studies have shown that perceived risk of GMOs…
Personalized SC-IAT
The Implicit Association Test (IAT) is used to assess attitude beyond the limitations of explicit measurements. Nevertheless, the test requires opposition between two attitude objects and also measures an extra-personal dimension of attitude that may reflect associations shared collectively. The first limitation can be overcome by using a Single Category IAT and the second by a personalized version of IAT. This study compares attitudes to smoking…
Normalization in the courtroom
Legal archives concerning a new type of offence first introduced onto the French statute books in 2005 reveal a normalization effect over the following 2 years in judges' sentence decisions but not in prosecutors' sentence demands. We examine the hypothesis that the formation of a normally accepted range of sentences will influence how judges respond to the extremity of the prosecutor's initial sentence demand. In line with a normalization perspe…
Cognitive processing of causal explanations
This article is aimed at providing further supporting evidence for the assumption that the cognitive processing of certain kinds of information is socially driven, even at very low levels of processing. More specifically, we hypothesize that knowledge associated with a social norm like the norm of internality (Jellison & Green, 1981; Beauvois & Dubois, 1988) may be more accessible in memory than knowledge associated with a non-normative register,…
