La socialisation des émotions chez le nourrisson: le rôle des expressions faciales contingentes des mères

Although maternal contingent responses to their infant's facial expressions of emotions is thought to play an important role in the socialization of emotions, available data are still scarce and often inconsistent To further investigate how mothers' contingent facial expressions might influence infant emotional development, we undertook to study mother‐infant dyads in four episodes of face‐to‐face interaction during the first year. Mothers' facial expressions were strongly related to their infant's facial expressions of emotions, most of their contingent responses being produced within one second following infants' facial expressions Specific patterns of responses were also found. The impact of maternal contingent responding on infants' expressive development was also examined.     

Geographic vocal variation and perceptual discrimination abilities in male Australian sea lions

Vocal characteristics can vary among and within populations. In species with geographic variation in the structure of vocalizations, individuals may have the ability to discriminate between calls from local and non-local individuals. The ability to distinguish differences in acoustic signals is likely to have a significant influence on the outcome of social interactions between individuals, including potentially mate selection and breeding success. Pinnipeds (seals, fur seals, sea lions and walruses) are highly vocal yet the Australian sea lion (Neophoca cinerea) is the only eared seal known to show geographic vocal variation in male barks. Barks are produced in many social interactions and encode sufficient information for both individual and colony identity to be discriminable. Yet until now, whether males could themselves discriminate these bark differences was unclear. We performed playback experiments in four breeding colonies to investigate whether males can discriminate local from non-local barks. Overall, males responded more strongly to barks from their own colony compared to barks from other colonies regardless of whether those other colonies were close or distant. Competition for females is high in Australian sea lions, but mating periods are asynchronous across colonies. The ability to correctly assess whether a male is from the same colony, thus representing a potential competitor for mates, or merely a visitor from elsewhere, may influence how males interact with others. Given the high cost of fighting, the ability to discern competitors may influence the nature of male–male interactions and ultimately influence how they allocate reproductive effort.     

Effets comportementaux et attitudinaux d’une procédure de Pied-dans-la-porte en entreprise

The present research investigates attitudinal and behavioral effects of a Foot-in-the-door paradigm (Freedman & Fraser, 1966), adapted to a company world. Moreover, it measures the impact of a variable whose integration to the paradigm has been discussed (Joule and Beauvois, 1998; Joule, Py & Bernard, 2004) although its effect has not been experimentally demonstrated: Action Identification (Vallacher and Wegner, 1985). Results show a response rate to the target request and a mean of affective commitment to the organization (Allen & Meyer, 1990) higher in the F.I.T.D. condition, particularly when the level of action identification is taking into account. Results are discussed in terms of commitment theory and action identification theory.     

Metacognition and low achievement in mathematics: The effect of training in the use of metacognitive skills to solve mathematical word problems

The central question underlying this study was whether metacognition training could enhance the two metacognition components—knowledge and skills—and the mathematical problem-solving capacities of normal children in grade 3. We also investigated whether metacognitive training had a differential effect according to the children's mathematics level. A total of 48 participants took part in this study, divided into an experimental and a control group, each subdivided into a lower and a normal achievers group. The training programme took an interactive approach in accordance with Schraw's (1998 Schraw, G. 1998. Promoting general metacognitive awareness. Instructional Science, 26: 113–125. [Crossref], [Web of Science ®] , [Google Scholar]) recommendation and was carried out over five training sessions. Results indicated that children in the training group had significantly higher post-test metacognitive knowledge, metacognitive skills, and mathematical problem-solving scores. In addition, metacognitive training was particularly beneficial to the low achievers. Thus metacognitive training enabled the low achievers to make progress and solve the same number of problems on the post-test as the normal achievers solved on the pre-test.     

Nonresident Suicides in England: A National Study

Little is known about the numbers and characteristics of people who travel away from home before dying by suicide. Therefore, this studied attempts to identify the sociodemographic characteristics, location, and method of suicide in people who died distant from home, in a national sample. Data were collected on all English suicides and a patient population; nonresident suicides resided in one Health Authority but died in a different one. Twelve percent of suicides were nonresident and features of these included: young age, social adversity, and severe mental illness. In conclusion, both individual‐ and area‐based factors are likely to contribute to suicide away from home.     

Perceptions of comparative optimism and perceptions of career success: Experimental evidence for a bidirectional effect

ABSTRACT

Audiences generally view people who display more (versus less) comparative optimism more favorably. We explored whether audiences view a target who displays comparative optimism as more professionally successful, and conversely, whether they view a target who is more professionally successful as more comparatively optimistic. In Study 1, participants estimated the career success of a target that varied in level of comparative optimism. In Study 2, participants estimated the level of comparative optimism of a target that varied in career success. The results revealed that observers rated comparative optimists as likely to have successful careers, and rated people with successful careers as likely to display comparative optimism. Inferences about personal agency account for the bidirectional relationship.
