L’intérêt pour la psychopathie infra-clinique n’est pas neuf. Toutefois, les études sur le sujet sont encore peu nombreuses. Notre recherche a consisté à mettre à l’épreuve deux hypothèses. La première, concerne la présence de « traits psychopathiques » dans la population tout-venant et la seconde tend à évaluer dans quelle mesure la présence de ces traits influence le traitement émotionnel. Pour tester ces hypothèses, nous avons créé une version « online » du SRP-III (Self Report Psychopathy). Aux soixante-quatre items initialement présents dans cette échelle nous avons ajouté dix-sept items afin d’être en mesure d’également coter la PCL-R (Psychopathy Check List- Revised). Deux groupes de chacun treize participants ont été créés sur base de leur score au SRP-III (un groupe « faibles caractéristiques psychopathique » et un groupe « fortes caractéristiques psychopathiques »). La seconde partie de l’étude consistait en une entrevue durant laquelle nous avons procédé à des mises en situation d’induction émotionnelle. Pour mesurer l’influence de cette induction, trois tâches cognitives étaient administrées aux sujets des deux groupes. La première hypothèse s’est vue confirmée à travers la récolte des données du questionnaire en ligne. Quant à la seconde hypothèse, les résultats statistiques n’indiquent aucune différence significative entre les groupes en ce qui concerne leur score aux tâches cognitives. Il est donc suggéré que la présence de traits psychopathiques n’influence pas le traitement émotionnel. Cette recherche confirme la présence de la psychopathie dans la population tout-venant et semble infirmer, parmi cette population, l’hypothèse d’un déficit du traitement émotionnel. [less ▲]

Verbal descriptions of unfamiliar faces have been found to impair later identification of these faces in children and adults, a phenomenon known as the “verbal overshadowing effect” (VOE, Schooler and Engstler-Schooler, 1990). The present study thoroughly examined the person descriptive abilities of 7–8, 10–11, and 13–14-year-old children and adults and their influence on later identification performance. Our aim was to specifically assess the prediction of the “content” account suggesting that a verbal overshadowing arises because participants generate an inadequate verbal description and later rely upon it during retrieval. Results showed a verbal overshadowing effect in all age groups but neither accuracy, length nor content of descriptions were found to be associated with identification accuracy. [less ▲]

False memories induced by the DRM procedure (“Deese, Roediger and McDermott”; Deese, 1959; Roediger & McDermott, 1995) or the misinformation procedure (in which a person’s recollection of a witnessed event is altered after exposure to misinformation about this event; Loftus et al., 1978) are due to errors in source monitoring processes (e.g., Johnson et al., 1993) and one might expect the correlation between these false memories quite positive. However, the few laboratory studies comparing the DRM paradigm and the misinformation paradigm show small (Zhu et al., 2013) or no correlation (Ost et al., 2013) between the false memories elicited by these procedures. However, these studies vary in terms of methodological details. For instance, false memories from the misinformation procedure involved emotional content while those from the DRM procedure only included neutral materials. This study investigated the relationship between false memories induced by two different paradigms (a DRM task and a misinformation procedure) both involving an emotional material. Participants (N = 154) completed an emotional variant of the DRM (neutral, positive and negative lists) and the misinformation (neutral, positive and negative images) procedures and their performances on both tasks were compared. Although both paradigms reliably induced false memories in participants, our analyses revealed only a marginally weak positive correlation (r = .147, p = .051) between misinformation and DRM false memories using emotional variants. These results support the idea that DRM and misinformation false memories are underpinned by (at least in part) different mechanisms and that the previous mixed results were not due to the specific content of the DRM or the misinformation task used.
