Harcèlement moral au travail et pro/antisocialité du salarié victime : quels effets sur les jugements,les émotions et les intentions d’aide des témoins ?

Bullying at work is characterized by negative, repetitive and frequent acts towards a person, bearing reached with her physical and psychic health (Einarsen, Hoel, Zapf, & Cooper, 2003; Leymann, 1996). On the basis of research of Weiner (1996) and Rudolph, Roesch, Greitemeyer, and Weiner (2004), we postulated that the bullying acts, the behaviors of the bullied employee and it revictimisation would influence the judgments and the emotions of the witnesses. Research was carried out within the framework of the paradigm of the judges of 72 participants. The variance analyses show that the gravity of the acts decreases the feeling of equity, increases the attribution of responsibility towards the harcelor, decreases the attribution of responsibility to the victim and increases the help. The bullying acts always interact with the victim’s pro or antisocial behaviors. The emotions of the judges are mainly positive with regard to the victim and negative towards the harcelor except when bullied employee has emitted an antisocial behavior. The gravity of the bullying acts increases on the one hand sympathy, fear and sadness towards the victims, on the other hand, anger and dislike towards the harcelor.     

Impact de la motivation autodéterminée et de l’engagement affectif sur l’intention de rester : une étude chez les militaires

Conducted within the Canadian Forces (N=652), this study explores the role of self-determined motivation and affective commitment in relation to personnel retention within the military. Three groupings of variables are used in order to shed light on the mechanisms underlying personnel retention: a) distal antecedents (i.e. leadership styles), b) proximal antecedents (i.e. group cohesion and work climate) and c) mediators (i.e. self-determined motivation and affective commitment). Illustrated through a structural model, results demonstrate the existence of a partial mediator effect from affective commitment in the relationship between self-determined motivation and intention to stay. These findings are discussed in regards of their implications from theoretical and practical perspectives.

Deficit of preparatory attention in frontotemporal dementia

We studied preparatory attention in patients suffering from frontotemporal dementia in the beginning stages of the disease, using an experimental test developed by LaBerge, Auclair, and Siéroff (2000). In this experimental test, a distracter can appear while subjects have to prepare to respond to a simple target. The probability that a distracter can appear in a trial is varied across three blocks. Normal controls show an increase of response times to targets (slope) as a function of the distracter probability, preparatory attention to the target is reduced by the increase of the distracter probability. Patients suffering from frontotemporal dementia show a slope of response times which is more than twice as large as the slope obtained by their matched controls. Such an abnormal increase of response times to targets is interpreted as a deficit in preparatory attention. Patients also show more omissions than controls. We suggest that this deficit in preparatory attention is related to the frontal lesion presented by the patients and can result in higher distractibility, a symptom frequently encountered in these patients.     

Procedural learning,consolidation, and transfer of a new skill in Developmental Coordination Disorder

The aim of this study was to explore the differences in procedural learning abilities between children with DCD and typically developing children by investigating the steps that lead to skill automatization (i.e., the stages of fast learning, consolidation, and slow learning). Transfer of the skill to a new situation was also assessed. We tested 34 children aged 6–12 years with and without DCD on a perceptuomotor adaptation task, a form of procedural learning that is thought to involve the cerebellum and the basal ganglia (regions whose impairment has been associated with DCD) but also other brain areas including frontal regions. The results showed similar rates of learning, consolidation, and transfer in DCD and control children. However, the DCD children's performance remained slower than that of controls throughout the procedural task and they reached a lower asymptotic performance level; the difficulties observed at the outset did not diminish with practice.     

Meeting the emotional needs of infants and toddlers in foster care: The collaborative mental health care experience

This paper describes a partnership between an infant mental health consultation program and child welfare authorities, with a special focus on the use of a consultation model to support infants and toddlers in foster care. The authors describe a model of practice that incorporates the transactional model with a developmental perspective to help foster parents understand and address the emotional needs of these children. The clinical implications section reviews strategies for addressing attachment and relationship disturbances, promoting self‐regulation, and enhancing social competence in infants and young foster children.     

Variations in size of the visual field in which targets are presented: An attentional range effect

In Experiment 1, subjects responded with a buttonpress to a target letter O embedded in a pair of vertical lines. A flanker control method was used to constrain the location and size of the initial attentional focus. The target could appear in one of five locations within a particular horizontal range. There were five ranges, varying from 1.7° to 8.6° in visual angle. Reaction time measures to the target exhibited V-shaped curves, with the lowest reaction time corresponding to the location of the initial focus of attention. The slopes of the curves decreased monotonically with target ranges. Reaction time measures at the extreme locations of the five ranges showed no significant increase with eccentricity, indicating that the influence of retinal sensitivity is negligible in this identification task as compared with the influence of other, presumably attentional, processes. Experiment 2 indicated that within a given range the slopes of the reaction time curves are independent of the number of locations probed. Additional evidence for the attentional range effect was given in Experiments 3 and 4, in which the tasks were detection of an asterisk both with and without flanking vertical lines and identification of the letter O with and without flanking lines. These results do not conform to predictions of a shifting focus theory of attention with the velocity of the focus assumed to be constant, or to the predictions of a gradient theory with total processing capacity assumed to be fixed.     

A cueing technique in choice reaction tlme

Much of the fluctuation in choice RT data is assumed to arise from variations in perceptual and response biases correlated with sequential patterns of trial events. Inserting a predictive cue prior to the stimulus on each trial apparently induces a strong bias not only toward that particular stimulus, but also toward its modality and toward the associated response. Trial-to-trial sequential effects under cued conditions were markedly smaller than those obtained in a noncued control condition.
