Blazing the trail versus trailing the group: Culture and perceptions of the leader’s position

Research suggests that power triggers assertive action. However, people from different cultures might expect different types of action from powerful individuals such as leaders. In comparing cultural differences in leadership imagery, we find that Americans represent leaders standing ahead of groups, whereas Asians also represent leaders behind groups. We propose that front versus back positions embody two faces of leader action: individual assertion versus group-focused action. Studies 1a and 1b respectively employed etic and emic methods to demonstrate that Singaporeans were more likely than Americans to represent leaders behind groups. In Study 2, Singaporeans evaluated back leaders more favorably than Americans did, and group focus mediated cultural differences. Simulating the conditions under which cultural differences arise, Study 3 demonstrates that a primarily Western managerial sample primed with threat (versus opportunity) preferred back leaders. By describing cultural variations in imagery, we reveal more nuanced implicit theories of leader action.     

Lactate threshold prediction by blood glucose and rating of perceived exertion in people with type 2 diabetes

The validity of rating of perceived exertion (RPE) in predicting lactate threshold during an incremental test was analyzed in 15 men with type 2 diabetes (M age = 53.4 yr., SD = 12.9). Blood glucose, lactate, and minute ventilation (VE)/VO2 responses identified the lactate, ventilatory, and glucose thresholds. Workloads (W) corresponding to RPEs 12, 13, 14, and 15 were determined. Second-order polynomials fit to VE/W and [lac]/W ratios corresponding to RPEs of 9-10, 12-13, and 16-17 also identified workloads above which there was an overproportional increase in VE and [lac]. These workload breakpoints did not differ, although at RPE 12 underestimated and at RPE 15 overestimated lactate threshold. RPE 13 and 14 and the responses of VE/W and [lac]/W to submaximal exercise accurately predicted lactate threshold.     

Blocking incidental frustration during bargaining

The current study examined the effects of an intervention aimed at blocking the transfer of frustration from a previous experience (i.e. recall task) to a subsequent and unrelated task (i.e. ultimatum bargaining task). Participants who went through the intervention were more likely to accept unfair offers in the ultimatum bargaining task than those who did not go through the intervention. These results show that participants who were blocked from transferring their feelings of frustration from the recall task to the subsequent bargaining task (no-transfer condition) more likely accepted unfair offers than those who inadvertently transferred their feelings of frustration (transfer condition). The effect of conditions on accept-reject decisions in the ultimatum bargaining was mediated by reported feelings of frustration.
