Pour une approche contextuelle et clinique de la demande de recrutement : la transformation d’une demande initiale dans une entreprise familiale

Studies of psychology in the work place usually analyse job offers from an explicit and functional point of view, forgetting the more implicit and strategic dimensions associated with them. This activity of recruitment takes into account the understanding of the specific context of the job offer and of the structure of the organisation which is looking to recruit. The clinical case study described here takes into consideration these contextual elements of very small company and proposes recruitment methods which include a third party, emphasising the particular role of psychologists or consultancies as recruitment advisers.     

Une base de données en sémantique du verbe : Semasit

In this article, we present Semasit, a semantic database for French verbs developed for the purposes of experimental research in psycholinguistics and neuropsychology. This database features the distribution of the agents and patients of 96 verbs of interpersonal relations, and 60 verbs of change of state, based on their probability of occurence for 100 participants. It also provides the free-association norms of these 156 verbs. The degree of imagery is also presented for some of them. For 24 verbs of interpersonal relations, this semantic database is completed by the distribution of the patients, when an agent and a verb are presented together. It also provides the free association norms of the patients in this case. This database in freely accessible and can be downloaded from the Internet: http://www.mshs.univ-poitiers.fr/lmdc/semasit/frame-index.htm.     

On realizable biorders and the biorder dimension of a relation

The paper discusses the mathematical foundations of a technique of multidimensional scaling, generalizing Guttman scaling, in which the structure of the embedding space relies only on ordinal concepts. An empirical relation is represented as an intersection of a minimal number (called bidimension) of Guttman relations. Fairly complete results are given for the cases of bidimensions 1 and 2. In the general case, the main results are based on the equivalence between the bidimension and the dimension of a certain partial order. A characterization of the bidimension as the chromatic number of some hypergraph is also provided.     

L’habilitation des salariés : le rôle du supérieur et des collègues

Organizational initiatives to empower employees have limited success if they are supported only by top managers. The goal of this study is to examine how two actors in the workers’ proximal social environment, the supervisor and colleagues, contribute to employee empowerment. A questionnaire study was conducted with a sample of 418 workers relying both on psychological and behavioral self-report measures of employee empowerment. Multiple regressions revealed that contributions from the supervisor and colleagues are distinct, additive and interact in a synergic way to increase employee empowerment. These results suggest that it is important to foster favorable conditions in the workers’ proximal social environment to instill employee empowerment.     

The effect of belief in weight controllability on anti-fat attitudes: An experimental manipulation

IntroductionAnti-fat attitudes reflect a type of discrimination on the basis of body weight and are one of the last accepted types of social stigma.ObjectiveTo evaluate the effect of exposure to priming messages about the causes of obesity on attitudes toward fat people.MethodParticipants (n = 580, M age = 22.19, 64.1% female) were randomly assigned to one of three possible conditions and then provided responses on three AFA subscales: Dislike, Fear of fat, and Willpower.ResultsPriming participants with messages confirming/challenging the weight controllability belief was associated with higher/lower levels on Willpower respectively compared to the control group. Unexpectedly, participants in both confirming and challenging groups showed significantly higher scores on Fear of fat. No differences were found on scores indicating Dislike.ConclusionThe current findings emphasize the effect of exposure to information about the causes of obesity on weight controllability beliefs.     

Be fearless: Positive affect as a mediator between venturesomeness and self-efficacy in future entrepreneurs and managers

Introduction and objectives

Self-efficacy, personality and different affect states in entrepreneurs and managers are important factors for effectiveness and well-being. The aim of the study was to examine in young adults during entrepreneurship-related education, the relationships between venturesomeness and self-efficacy, and the mediating effects of positive affect and positive emotions (joviality, self-assurance, attentiveness) on these relationships.

Can sleep habits predict driver behaviour?

IntroductionThe role of sleep hygiene (those factors that promote or disrupt effective sleep) on human performance was examined.ObjectiveThe study investigated the relationship between sleep hygiene and crash involvement.MethodMeasures of sleep hygiene and crash involvement were considered for a sample of over 6000 drivers.ResultsIt was found that poorer sleep hygiene was associated with younger age and greater crash involvement. The association between sleep hygiene and crash involvement remained when age and risk taking had been taken into account.ConclusionPoor sleep hygiene is associated with poorer performance as measured by crash involvement.     

La mémoire à long terme des durées : fonctionnement et développement

Estimating the duration of an event often requires that we reference our own knowledge about the duration of similar events stored in long-term memory. The ability to preserve these durations in long-term memory therefore seems to serve an important function in time estimation. However, relatively few studies on this topic appear in the psychology literature. In the present article, we describe how time estimation models have treated long-term memory, and discuss relevant empirical data obtained from adults. Then, we present the results of recent experiments that examine 3- to 8-year-old children’s ability to maintain durations in memory, depending on the kind of previous experience the children have had with these durations.     

Les effets de la modalité sensorielle sur la perception du temps

The subjective duration of an event can be influenced by the modality of the signal demarcating that event. For example, auditory signals are often judged as of longer duration than equivalent duration visual signals. Within the framework of pacemaker-accumulator models of timing, such modality effects raise the question of whether the internal clock is modality specific or amodal. The answer to this question is quite important for the development of cognitively and neurologically realistic models of timing and time perception. Here, we argue that the internal clock has both modality specific and amodal components. Specifically, we claim there is a common amodal pacemaker, but the switch-accumulator systems are modality specific. Moreover, we also posit that long-term memory representations of duration are stored amodally.     

On children's interpretations of negation

French children between 4 and 10 years old were asked to draw representations of French negative sentences. The results indicated that in most cases only the verb is negated when the noun phrase to the right of the negation is introduced by a definite article, but when the noun phrase is introduced by an indefinite article, it is most often the noun phrase itself that is negated. This effect is clear even in 4-year-olds, and it serves to demonstrate that the interpretation of negative sentences depends on phenomena of surface structure as well as of deep structure.
