What good leaders actually do: micro-level leadership behaviour,leader evaluations,and team decision quality

We supplement broad definitions of leadership behaviour with the concept of micro-level leadership behaviour, leaders’ verbal and non-verbal visible conduct and interaction. For the context of team decision-making, we identify two potentially beneficial micro-level leadership behaviours, question asking and behavioural mimicry. Specifically, we propose that under conditions of informational complexity and unshared information, participative leadership is most appropriate for team decision-making, that its effects are mediated by inquiring and empathy, and that question asking and mimicry are the behavioural micro-level manifestations of inquiring and empathy. We thus hypothesize that the effect of participative leadership on team decision quality and leader evaluation is mediated by question asking and mimicry. We conduct a laboratory experiment with student teams working on a hidden profile decision-making task and measure question asking through behavioural coding and mimicry with motion sensors. Results show that the effect of participative leadership on decision quality is mediated by question asking, and that the effect of participative leadership on leader evaluation as transformational is mediated by leaders’ behavioural mimicry and question asking. Under control of these micro-level behaviours, team decision quality and leader evaluations were unrelated.     

Linking job demands and resources to burnout and work engagement: Does passion underlie these differential relationships?

This study examined the role of passion for work in the health impairment and motivational processes proposed by the job demands-resources model. Based on the dualistic model of passion, we proposed that harmonious and obsessive passion intervene simultaneously in the relationship between (1) job demands and burnout/engagement, and (2) job resources and burnout/engagement. This model was tested in two occupational samples: nurses (n = 1,179) and teachers (n = 745). Results from structural equation modeling support the proposed model in both samples. That is, both types of passion partially mediated the relationship between job demands and burnout, while harmonious passion partially mediated the relationship between job demands and engagement. Moreover, harmonious passion partially mediated the relationship between job resources and burnout/work engagement. Implications for burnout research and management practices are discussed.     

A 21st century cognitive portrait of the Himba,a remote people of Namibia

This research sketches the cognitive portrait of the Himba, a remote population from Northern Namibia living in a non-industrial society almost completely devoid of modern artefacts. We compared the Himba sample to a French sample, exploring cognitive reflection, moral judgement, cooperative behaviour, paranormal beliefs, and happiness. We looked for both differences and similarities across cultures, and for the way cognitive functioning is associated with a range of demographic variables. Results showed some important group differences, with the Himba being more intuitive, more religious, happier, and less utilitarian than the French participants. Further, the predictors of these beliefs and behaviours differed between the two groups. The present results provide additional support to the recent line of research targeting cultural variations and similarities, and call for the need to expand psychology research beyond the Western world.     

Preserved topographical memory following right temporal lobectomy

In an attempt to study remote memory for visuospatial information, geographical knowledge was examined in patient J.N., who had received a radical right temporal lobectomy to remove a large glioblastoma. In postoperative tests J.N. displayed severe deficits in anterograde memory for visuospatial and verbal material, visuoperceptual functions, constructions, attention, and response initiation. Despite her global cognitive deficiencies she performed normally on the WAIS Information Scale and the Fargo Map Test, a measure of geographical knowledge. In contrast, patients known to have severe amnesia exhibited impairments on tests of geographical knowledge that required precise localization of features such as cities. Assuming that J.N.'s performance is typical of patients with extensive damage to the right temporal lobe, the findings suggest that the integrity of the right temporal lobe is not essential for the retrieval of premorbidly established visuospatial memories.
