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.     

INTRAORGANIZATIONAL EMPLOYEE NAVIGATION AND SOCIALLY DERIVED OUTCOMES: CONCEPTUALIZATION,VALIDATION, AND EFFECTS ON OVERALL PERFORMANCE

Intraorganizational employee navigation (IEN) is conceptualized as a means of better understanding how the organizational actor proactively works across their firm's internal environment in the execution of their jobs. Navigation is argued to be a precursor to the employee's overall performance through a class of mediating variables labeled “socially derived outcomes,” which are variables inside the organization that are bestowed upon the employee as a result of them first engaging in proactive behavior (e.g., IEN). Two studies are reported. Study I sees IEN psychometrically validated versus a range of existing proactive behaviors and individual traits (discriminant, nomological, and criterion‐related validity) with a heterogeneous sample of 704 employees. Study II then tests a model relating IEN to performance through six mediating “socially derived outcomes” by leveraging data from 2 Fortune 500 firms. The results of Study II show that IEN significantly impacts multiple measures of the employee's overall performance through mediating effects brought about by key socially derived outcomes, such as the employee's “manager alignment.” The contributions, broader implications, and limitations of the research are then put into context.     

When can categorical variables be treated as continuous? A comparison of robust continuous and categorical SEM estimation methods under suboptimal conditions

A simulation study compared the performance of robust normal theory maximum likelihood (ML) and robust categorical least squares (cat-LS) methodology for estimating confirmatory factor analysis models with ordinal variables. Data were generated from 2 models with 2-7 categories, 4 sample sizes, 2 latent distributions, and 5 patterns of category thresholds. Results revealed that factor loadings and robust standard errors were generally most accurately estimated using cat-LS, especially with fewer than 5 categories; however, factor correlations and model fit were assessed equally well with ML. Cat-LS was found to be more sensitive to sample size and to violations of the assumption of normality of the underlying continuous variables. Normal theory ML was found to be more sensitive to asymmetric category thresholds and was especially biased when estimating large factor loadings. Accordingly, we recommend cat-LS for data sets containing variables with fewer than 5 categories and ML when there are 5 or more categories, sample size is small, and category thresholds are approximately symmetric. With 6-7 categories, results were similar across methods for many conditions; in these cases, either method is acceptable. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Evaluation of a novel translational task for assessing emotional biases in different species

Changes in the processing of emotional information are key features of affective disorders. Neuropsychological tests based on emotional faces or words are used to detect emotional/affective biases in humans, but these tests are not applicable to animal species. In the present study, we investigated whether a novel affective tone discrimination task (ATDT), developed to study emotion-related behaviour in rats, could also be used to quantify changes in affective states in humans. To date, the methods used in human neuropsychology have not been applicable to animal experiments. Participants completed a training session in which they learnt to discriminate specific tone frequencies and to correctly respond in order to gain emotionally valenced outcomes, to obtain rewards (money), or to avoid punishment (an aversive sound clip). During a subsequent test session, additional ambiguous probe tones were presented at frequencies intermediate between the reward and avoidance paired tones. At the end of the task, participants completed self-report questionnaires. All participants made more avoidance responses to the most ambiguous tone cues, suggesting a bias towards avoidance of punishment. Individual differences in the degrees of bias observed were correlated with anxiety measures, suggesting the task’s sensitivity to differences in state anxiety within a healthy population. Further studies in clinical populations will be necessary to assess the task’s sensitivity to pathological anxiety states. These data suggest that this affective tone discrimination task provides a novel method to study cognitive affective biases in different species, including humans, and offers a novel assessment to study anxiety.     

Effects of workaholism on volunteer firefighters’ performance: a moderated mediation model including supervisor recognition and emotional exhaustion

ABSTRACT

Background and Objectives: Although workaholism has been associated with job performance, the mechanisms that explain this relationship remain unclear. In this study, we investigated the conditional indirect effects of workaholism on performance via emotional exhaustion, across low and high levels of supervisor recognition.

Methods: We conducted an empirical cross-sectional study using a sample of 1028 volunteer firefighters who completed a self-report questionnaire assessing workaholism, emotional exhaustion, work performance, and supervisor recognition.

Results: Tests of latent interactions were performed using the latent moderated structural equation modeling approach. Consistent with our predictions, results revealed that the negative indirect effects of workaholism on performance, through emotional exhaustion, were stronger when supervisor recognition was low.

Conclusions: Theorical contributions and perspectives, as well as implications for practice are discussed.     

Inhibitory deficits and symptoms of attention-deficit hyperactivity disorder: How are they related to effortful control?

Separate studies with clinical and community-based samples have identified an association between symptoms of attention-deficit hyperactivity disorder (ADHD) and inhibitory control deficits and ADHD and weak effortful control. We tested whether differences in effortful control explained the associations between ADHD symptoms and inhibitory control deficits, controlling for conduct problems. In a community sample, parents rated ADHD symptoms, conduct problems, effortful control, surgency and negative affect in 77 4-7-year-olds (47 girls), who performed an inhibitory control task. ADHD symptoms, deficient inhibitory control and low effortful control were correlated. Controlling for conduct problems, path analysis showed the ADHD symptoms – inhibitory control link was mediated statistically by effortful control. This focuses attention on cognitive-energetic factors associated with ADHD-related executive deficits.     

The More the Merrier? Sibling Composition and Early Manifestations of Theory of Mind in Toddlers

Sibling relationships are argued to offer a rich social context for the development of young children’s theory of mind (ToM). There is evidence that the presence of siblings, particularly older siblings, may promote preschoolers’ ToM, but it has not been investigated among toddlers. This study evaluated differences in early manifestations of ToM between toddlers in different sibling compositions: 1) without a sibling, 2) with younger siblings only, and 3) with older siblings only. The sample included 227 toddlers who completed 2 tasks assessing their understanding of discrepant desires and visual perspectives. Results indicated that only children and those who had older siblings did not differ from each other on either task. However, on both tasks, toddlers with younger siblings performed significantly more poorly compared with those with older siblings. Moreover, children with younger siblings demonstrated poorer visual-perspective understanding compared with only children. It may be critical to take siblings’ birth order into account when investigating their respective effects on each other’s ToM, especially in toddlerhood.
