However, recent researches reveal that, emotion and cognition also play a pivotal role in the expression of fish behaviour. Fish exhibit fear, long-term memory, attentional and learning capacities that are comparable with those of other vertebrates, including nonhuman primates. Thus, fish can be expected to manage motivational conflicts using cognitive similar resources. As many other teleost fishes, zebrafish (Danio rerio) is a good candidate to investigate the behavioural effects of approach–avoidance conflicts because of its genetic and neurophysiological proximity with “higher” vertebrates. The present study aims to determine how Zebrafish reacted to threats of different magnitude (low vs. high) following the delivery of food. <br/> <br/>Commentary: Integral text in Program and Abstracts Book, pp. 261-262: see pdf file "YLIEFF-Marc-&-al-Abstract-ECI-2012-Liège-ABSTRACT-BOOK.pdf", in Open Access.

Twenty-four participants with TBI and 28 control participants adopted facial expressions and body postures according to specific instructions and maintained these positions for 10 seconds. Expressions and postures entailed anger, sadness, and happiness as well as a neutral (baseline) condition. After each expression/posture manipulation, participants evaluated their subjective emotional state (including cheerfulness, sadness, and irritation). TBI participants were globally less responsive to the effects of body and facial feedback than control participants, F (1, 50) = 5.89, p = .02, η2 = .11. More interestingly, the TBI group differed from the Control group across emotions, F (8,400) = 2.51, p = .01, η2 = .05. Specifically, participants with TBI were responsive to happy but not to negative expression/posture manipulations whereas control participants were responsive to happy, angry, and sad expression/posture manipulations. In conclusion, TBI appears to impair the ability to recognise both the physical configuration of a negative emotion and its associated subjective feeling.

This study used the distinction between item and order retention processes to achieve a better understanding of STM deficits in adults with dyslexia. STM for item information has been shown to depend on the quality of underlying phonological representations, and hence should be impaired in dyslexia, which is characterized by poorly developed phonological representations. On the other hand, STM for order information is considered to reflect core STM processes, which are independent from language processing. Thirty adults with dyslexia and thirty control participants matched for age, education, vocabulary, and IQ were presented STM tasks, which distinguished item and order STM capacities. We observed not only impaired order STM in adults with dyslexia, but this impairment was independent of item STM impairment. This study shows that adults with dyslexia present a deficit in core verbal STM processes, a deficit which cannot be accounted for by the language processing difficulties that characterize dyslexia. Moreover, these results support recent theoretical accounts considering independent order STM and item STM processes, with a potentially causal involvement of order STM processes in reading acquisition.

À l’aide de cette conceptualisation, nous avons exploré quatre aspects peu étudiés ou sujets à débats du vagabondage de l’esprit que sont les fonctions possibles de ce phénomène, ses soubassements cérébraux, le lien qu’il entretient avec les capacités de contrôle de l’attention, ainsi que la nature de la relation entre le vagabondage de l’esprit et les affects négatifs. Les résultats des études réalisées au sein de ce travail suggèrent qu’une fonction importante du vagabondage de l’esprit concerne la planification et la préparation des évènements futurs en lien avec nos buts et projets personnels. Notre travail démontre par ailleurs que le vagabondage de l’esprit est sous-tendu par un ensemble spécifique de régions cérébrales (généralement référenciées sous le terme de réseau du mode par défaut) et que ce phénomène représente plus que des échecs au niveau des processus de contrôle de l’attention en impliquant notamment un état d’attention découplée de l’environnement présent. Nous avons également montré que le vagabondage de l’esprit peut résulter d’une augmentation des affects négatifs et que sa présence est associée au maintien de ces affects dans le temps. Le fait que les individus qui vagabondent le plus en pensées font l’expérience d’un plus haut taux d’affects négatifs pourrait être expliqué par une moindre conscience et attention portées au moment présent. Sur base de ces résultats, nous avons proposé une perspective intégrative du vagabondage de l’esprit qui suppose que ce phénomène représente l’accès à la conscience, à travers un espace de travail global limité, des processus de mise à jour des scripts, schémas et plans stockés en mémoire à long terme et sous-tendus par le réseau du mode par défaut. La fonction de ces scripts, schémas et plans serait de guider les comportements des individus en formant une plate-forme cognitive impliquée dans la génération de prédictions relatives au futur. Nous avons dès lors proposé que le vagabondage de l’esprit peut représenter un phénomène adaptatif mais uniquement lorsque les bénéfices de ces pensées en termes de préparation et de planification du futur dépassent leurs conséquences délétères sur la qualité de l’attention portée à la tâche en cours et au moment présent.

Since reports of NDEs are proposed to be imagined events, and since memories of imagined event have, on average, fewer phenomenological characteristics than real events memories, we here compared phenomenological characteristics of NDEs reports with memories of imagined and real events. We included three groups of coma survivors (8 patients with NDE as defined by the Greyson NDE scale, 6 patients without NDE but with memory of their coma, 7 patients without memories of their coma) and a group of 18 age-matched healthy volunteers. Five types of memories were assessed using Memory Characteristics Questionnaire (MCQ – Johnson et al., 1988): target memory (NDE for NDE memory group, coma memory for coma memory group, and first childhood memory for no memory and control groups), old and recent real event memories and old and recent imagined event memories. Since NDEs are known to have high emotional content, participants were requested to choose the most emotionally salient memories for both real and imagined recent and old event memories. Results showed that, in NDE memories group, NDE memories have more characteristics than memories of imagined and real events (p<0.02). NDE memories contain more self-referential and emotional information and have better clarity than memories of coma (all p<0.02). The present study showed that NDE memories contain more characteristics than real event memories and coma memories. Thus, this suggests that they cannot be considered as imagined event memories. On the contrary, their physiological origins could lead them to be really perceived although not lived in the reality. Further work is needed to better understand this phenomenon. <br/> <br/>Commentary: MT & VCV contributed equally to this work Mon, 29 Apr 2013 15:12:59 GMT http://hdl.handle.net/2268/147309 Title: Troubles spécifiques de développement du langage.
