Asymmetric Effects of Holding Power Versus Status: Implications for Motivation and Group Dynamics.

Although extant research suggests that power without status, but not status without power, induces interpersonal conflict, we are yet to fully understand the asymmetric effects of holding power or status on psychological processes and group functioning. The present research attempts to fill this gap by arguing that holding power would heighten the motivation for status, whereas holding status may not necessarily have an equivalent effect on the motivation for power. We further proposed that power-status misalignment within a group would lead powerholders to be competitive toward statusholders due to heightened status motive and (upon failure to attain status) invest less in their group due to greater emotional distress. Across four (and one Supplemental) studies, we found support for our hypotheses. Our findings not only shed further light on the interactive effects of power and status, but also help better explain why power without status is particularly related to negative outcomes.

Sparse Extended Redundancy Analysis: Variable Selection via the Exclusive LASSO.

Extended Redundancy Analysis is a statistical tool for exploring the directional relationships of multiple sets of exogenous variables on a set of endogenous variables. This approach posits that the endogenous and exogenous variables are related via latent components, each of which is extracted from a set of exogenous variables, that account for the maximum variation of the endogenous variables. However, it is often difficult to distinguish between the true variables that form the latent components and the false variables that do not, especially when the association between the true variables and the exogenous set is weak. To overcome this limitation, we propose a Sparse Extended Redundancy Analysis via the Exclusive LASSO that performs variable selection while maintaining model specification. We validate the performance of the proposed approach in a simulation study. Finally, the empirical utility of this approach is demonstrated through two examples-one on a study of youth academic achievement and the other on a text analysis of newspaper data.
