Leader self-projection and collective role performance: A consideration of visionary leadership

Leaders often need to project themselves into alternative situations, but there is a limited understanding of how, why, or when leader self-projection might influence their teams’ outcomes. Based on the notion that brain activity in the default mode network (DMN) underlies self-projection, such as future-oriented mental simulations, we argue that the effect of leaders’ DMN activity on team behavior such as collective role performance may be understood by considering both the leaders’ visionary behavior and their orientation towards socialized vision. Specifically, we posit that a leader’s trait-like brain activity in the leader’s DMN is associated with the leader’s visionary behavior. Furthermore, we argue that visionary leader behavior, when accompanied by socialized vision orientation, facilitates collective role performance of the team. As such, we examine the moderating role of a socialized orientation toward serving the interests of a wide range of stakeholders in reinforcing the positive effect of visionary leader behavior on collective role performance of team members, as well as the indirect effect of leader DMN activity on collective role performance via visionary leader behavior. We found support for our hypotheses using diverse research methodologies, including quantitative electroencephalogram (qEEG), multi-source multi-wave surveys, and interview coding.     

Eyes on the account size: Interactions between attention and budget in consumer choice

The context surrounding a consumer decision, such as one’s overall budget available for purchases, can exert a strong effect on the subjective value of a product. Across three eye-tracking studies, we explore the attentional processes through which budget size influences consumers’ purchasing behavior. Higher budgets increased and sped up purchasing even when items were affordable at all budget sizes. Moreover, attention interacted with budget size to promote purchasing at higher budgets. Finally, individual differences in the magnitude of the budget effect related to attentional patterns: those whose decisions depended more on budget exhibited more budget-price transitions and less variability in search patterns compared to those whose decisions were less dependent on budget. These findings indicate that attention moderates the effect of budgets on purchasing decisions, allowing low budgets to serve as self-control devices and large budgets to generate impulse purchases.
