Sight or smell: which senses do scavenging raptors use to find food?

Animal Cognition - Raptors are usually considered to be mainly visually dependent, and the use of other sensory modalities has rarely been studied in these birds. Here, we investigated...     

Persistence in a Putting Task During Perceived Failure: Influence of State-attributions and Attributional Style

Dans cette étude, on a examiné l’influence de l’état des attributions et le style attributionnel (AS) sur la persistance à court‐terme d’un échec perçu à une tâche de putting. 101 élèves débutants en golf ont participéà cette recherche. Deux épreuves de 8 putts ont été interrompues chacune pendant trois minutes. Durant cette période, on a mesuré la persistance individuelle en comptant le nombre de fois que le sujet essayait de putter. L’analyse des résultats montre que le style attributionnel influence la persistance à court‐terme contrairement à l’état des attributions. Les sujets ayant un AS “fort contrôle personnel” font montre de plus de persistance que ceux ayant un AS “faible contrôle personnel”. Ces résultats confirment ceux obtenus lors de recherches antérieures sur les bénéfices motivationnels d’un style attributionnel “optimiste” dans des situations d’échec lors de la réalisation d’une tâche. Des attributions instables sont particulièrement bénéfiques aux sujets ayant un AS externe/incontrôlable. Ces derniers ont un niveau significativement plus élevé de persistance que les sujets ayant un AS externe/incontrôlable mais qui ont fait des attributions causales stables. This study investigated the influence of state‐attributions and attributional style (AS) on short‐term persistence in a putting task during perceived failure. Participants were 101 novice golf students. Two trials of eight putts each were interrupted by a 3‐minute free period during which individual persistence was measured by calculating the number of putts attempted in the free period. Analyses revealed that attributional style influenced short‐term putting persistence but state‐attributions did not. Participants with a “high personal control” AS showed greater persistence than those with a “low personal control” AS, which supports past research on the positive motivational benefits of a more “optimistic” attributional style in task failure situations. Moreover, unstable attributions were particularly protective for individuals with an external/uncontrollable AS, in that they promoted significantly higher levels of persistence than was shown by external/uncontrollable AS individuals who made stable causal attributions.     

Kaiho Seiryō on ‘What it is to be a Human Being’

Kaiho Seiryō (1755–1817) is probably the first Japanese thinker to proclaim the contractual nature of human relationships. I examine in this paper the view of human beings that led him to this conclusion. Giving up previous definitions of humans, Seiryō focuses on the faculty of practical reason. While this leads him to recognize a hierarchy of humans, some having more humanity than others, it also allows him to develop the most modern understanding of social relationship available in his time. His radical reinterpretation of what it is to be a human being is all the more remarkable because it was done with the concepts and ideas provided by the Chinese Classics. Establishing new connections, giving new life to ideas that were never exploited, Seiryō showed it was possible to make sense of modernity without using foreign concepts.     

Moderating effect of emotional intelligence on the role of negative affect in the motivation to drink in alcohol-dependent subjects undergoing protracted withdrawal

In order to understand how emotional aspects evolve and are related to craving for alcohol, different emotion-related variables were examined in relationship to craving during a protracted withdrawal. To this end state affectivity (PANAS), emotional intelligence (EI) (TEIQue), and craving (OCDS) were assessed at the onset (T1: day 1 or 2) and at the end (T2: day 14 to 18) of three-week protracted withdrawal among alcohol-dependent inpatients (DSM-IV, N = 41). A significant decrease in craving and negative affectivity (NA) was observed from T1 to T2 while EI scores remained low. At both baseline and follow-up, there was a significant moderation effect of EI on the link between NA and craving for alcohol. Negative mood at the onset of the cure was linked to craving at the end of the withdrawal period but only among patients with low trait EI scores. The merits of using psychotherapeutic approaches were discussed in the treatment of alcohol addiction.     

Motor planning between 4 and 7 years of age: Changes linked to executive functions

In the present study, we adopted the conceptual frameworks of Miyake et al. (2000) (organization of executive functions) and Sergeant (2000) (linking executive function to motor behaviour) to assess developmental changes in executive functions and motor behaviour, using a planning task with a sample of 4–7-years old children. More precisely, the aim of the study was to characterize the development of motor response planning between the ages of 4 and 7 as a measure of the integration of multiple executive function processes, namely inhibition, shifting and working memory, and to gain insight into the concurrent developmental contributions of these processes. Participants were divided into two groups: group 1 was composed of 24 children aged 4–5 years and group 2 was composed of 20 children aged 6–7 years. Each participant took tests for shifting, inhibition, working memory and motor planning (the egg-planning task). Our results suggest that the egg-planning task requires the inhibition of a pre-potent but inappropriate response, and to a lesser extent the manipulation of working memory strategies. These results are discussed in relation to the development of each executive function component.     

The influence of alexithymia and music on the incidental memory for emotion words

Alexithymia is a multifaceted personality construct which encompasses difficulties in identifying and expressing feelings along with an externally oriented cognitive style. We investigated whether congruent vs. incongruent emotional musical priming (happy and angry music) during encoding would moderate the effects of alexithymia on recognition rates. We found that high alexithymia scorers recognized fewer joy and anger words than low scorers. Angry music decreased recognition rates in high alexithymia scorers compared to low alexithymia scorers. The congruency and incongruency effects between music and words depended on alexithymia level. The anger deficit in high alexithymia scorers and the possible support provided by happiness cues are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Development of category formation for faces differing by age in 9‐ to 12‐month‐olds: An effect of experience with infant faces

We examined category formation for faces differing in age in 9‐ and 12‐month‐olds, and the influence of exposure to infant faces on such ability. Infants were familiarized with adult or infant faces, and then tested with a novel exemplar from the familiarized category paired with a novel exemplar from a novel category (Experiment 1). Both age groups formed discrete categories of adult and infant faces, but exposure to infant faces in everyday life did not modulate performance. The same task was conducted with child versus infant faces (Experiment 2). Whereas 9‐month‐olds preferred infant faces after familiarization with child faces, but not child faces after familiarization with infant faces, 12‐month‐olds formed discrete categories of child and infant faces. Moreover, more exposure to infant faces correlated with higher novel category preference scores when infants were familiarized with infant faces in 12‐month‐olds, but not 9‐month‐olds. The 9‐month‐old asymmetry did not reflect spontaneous preference for infant over child faces (Experiment 3). These findings indicate that 9‐ and 12‐month‐olds can form age‐based categories of faces. The ability of 12‐month‐olds to form separate child and infant categories suggests that they have a more exclusive representation of face age, one that may be influenced by prior experience with infant faces.     

Applying the SIDE model to brainwriting: The impact of intergroup comparison and anonymity on creative performance

According to the Social Identity model of Deindividuation Effects, intergroup comparison under anonymity accentuates social identity salience, potentially increasing motivation to work for one's group. The present experiment aimed to examine whether intergroup comparison and anonymity could boost creative performance in a brainwriting task. Sixty participants, randomly assigned to groups, wrote their ideas on sticky notes of the same (anonymity) or different color (individuation). To reinforce social identity salience, half the groups were told that their performance would be compared with other groups. As predicted, anonymity and intergroup comparison boosted both the number of nonredundant ideas produced by group members (fluency), and diversity of ideas pertaining to different categories (flexibility). By contrast, when social identity was not salient, anonymity led to an increase in the originality of ideas.
