Drawing from the neuroscience literature and recent advancements in sleep technology, we examine how closed loop acoustic stimulation can improve employee sleep and subsequent work behaviors. Specifically, we hypothesize that because closed loop acoustic stimulation improves sleep quality, it enhances work engagement, task performance, and organiza...

In this article, we investigate the effects of leader subjective ambivalence on team performance. Integrating the ambivalence literature and social learning theory, we propose a multi‐level model of whether, when, and why team leaders’ subjective ambivalence enhances team performance outcomes. The results of two laboratory experiments (Studies 1 an...

Psychological ownership represents feelings of responsibility for and possession over a target, which can be both tangible in terms of physical resources, or intangible regarding one's relationships. Here we examine how two well-established leadership styles can trigger six different facets of psychological ownership and their corresponding ownersh...

Investors in early-stage companies want to detect and select high-potential opportunities to maximize their long-term returns. However, in this uncertain and risky investment context, company information is often opaque and decision-making timeframes are compressed. Although there is an abundance of prior work on how investors make structured decis...

In recent years, scholars have become increasingly interested in the effects of organizations’ corporate social responsibility (CSR) efforts on observers’ perceptions and behaviors. We extend this literature by drawing from person perception theories and ethics research to propose that CSR impacts shareholders’ approval of TMT compensation packages...

Controlling impulses and overcoming temptations (i.e., self-control) are key aspects of living a productive life. There is a growing yet disperse literature indicating that sleep is an important predictor of self-control. The goal of this meta-analysis is to empirically integrate the findings from multiple literatures, and investigate whether sleep...

We investigate the impact of the circadian process (24-h biological cycles that influence sleep/wake periods) and chronotypes (individual differences in the timing of those cycles) in charismatic leadership. We theorize that the expressions of charismatic signals by leaders, and the perceptions of those signals by followers are influenced by the ci...

In this article, we investigate the effects of blue-light filtration on broad attitudinal and behavioral outcomes (i.e. work engagement, organizational citizenship behavior, and counterproductive work behavior). Drawing on recent developments in the circadian process literature and its related research on chronobiology, we propose that a cost-effec...

Research on employee misconduct has increasingly adopted behavioral measures in field settings, such as archival organizational records, to circumvent potential issues of external validity and social desirability associated with laboratory experiments and self-reported surveys. However, similar to the issues facing the criminal justice and educatio...

This paper advances the understanding of managerial voice endorsement based on a self‐regulation perspective. We suggest that although managers might potentially benefit more from employees’ upward voice when they are more depleted, they are paradoxically less likely to diligently process or endorse such voice under ego depletion. We draw from ego...

Laboratory experiments have many benefits and serve as a powerful tool for social psychology research. However, relying too heavily on laboratory experiments leaves the entire discipline of social psychology vulnerable to the inherent limitations of laboratory research. We discuss the benefits of integrating archival research into the portfolio of...

In this article we examine the effects of manager-subordinate gender match on managerial response to employee voice. Drawing from social comparison theory, we propose that managers high on social comparison orientation respond more favorably to voice expressions that come from opposite-gender subordinates than to those from same-gender ones. Given...

Drawing from the sleep and emotion regulation model, and attribution theory, we argue that sleep can influence the quality of the relationship between leaders and their followers. Specifically, we examined the effects of lack of sleep on leader-follower relationship development at the beginning of their dyad tenure. We hypothesized that the negativ...

While largely untested, theorizing concerning transformational leadership has suggested that its effects will vary depending on the extremity of the context in which this leadership style is exercised. Further, knowing how to retain employees after they are exposed to the stresses and trauma of extreme events remains a challenge for organizations t...

The degree of punishment assigned to criminals is of pivotal importance for the maintenance of social order and cooperation. Nonetheless, the amount of punishment assigned to transgressors can be affected by factors other than the content of the transgressions. We propose that sleep deprivation in judges increases the severity of their sentences. W...

We draw from theory on sleep and affect regulation to extend the emotional labor model of leadership. We examine both leader and follower sleep as important antecedents of attributions of charismatic leadership. In Study 1, we manipulate the sleep of leaders, and find that leader emotional labor in the form of deep acting (but not surface acting or...

In this article we investigate the functional effects of ambivalence on decision-making processes. We build on the misattribution literature and recent work on ambivalence to propose that individuals who properly identify the causes of their ambivalence (i.e., identified ambivalence) can systematically process relevant situational cues to make more...

In this article, we theoretically develop and test the temporal intricacies of job engagement. Drawing on the attention view of social cognition, we examine the interplay of employees’ temporally relevant perspectives of fit (i.e., retrospected, current, and anticipated) within their ongoing membership to the organization. Utilizing field data gath...

Compared to macro-organizational researchers, micro-organizational researchers have generally eschewed archival sources of data as a means of advancing knowledge. The goal of this paper is to discuss emerging opportunities to use archival research for the purposes of advancing and testing theory in micro-organizational research. We discuss eight sp...

In this article we investigate the functional effects of ambivalence on decision-making processes. We build on the misattribution literature and recent work on ambivalence to propose that individuals who properly identify the causes of their ambivalence (i.e., identified ambivalence) can systematically process relevant situational cues to make more...

Over the last thirty years, measures of transformational leadership have been positively related to a broad range of individual, unit and organizational performance outcomes. Most of this literature has focused on examining the motivation and performance of individuals who stay with organizations, while relatively few studies have examined how tran...

Accumulated research has suggested that a majority of managers tend to be averse to and reject follower voice. We build on social comparison theory and social categorization theory to propose that leaders’ response to follower voice might vary based on whether the follower who expresses voice is of the same gender as the leader. Experimental data g...

There is growing consensus among leadership scholars that followers can play a significant role in influencing their leaders’ interpretative processes. Leadership theory, however, has yet to explain how and when leaders and followers collaboratively build sense of organizational complexity to make decisions. In this article, we introduce the constr...

Scholars of transformational leadership and leader–member exchange (LMX) have argued that leaders are able to positively influence the job attitudes and behaviors of followers by different means. Whereas transformational leadership focuses on the leaders’ ability to transform followers through a global inspiring vision that encourages positive chan...

There is growing consensus among scholars that the organizational environment has become increasingly complex, dynamic, and socially demanding. Leaders and followers navigate through a cognitive paradox where assessments of the situation can be at once cognitively overpowering and cognitively deceiving. In this article, we propose that complex situ...

In this article I propose a conceptual model to investigate the effects of emotional labor on unethical behavior. By drawing on Affect Infusion Model (Forgas, 1995) and the social intuitionist model (Haidt, 2007) I develop theoretical arguments to justify why and how surface acting lead to high levels of unethical behavior whereas deep acting has t...
