2020-05-03

This Is What Happens To Your Brain When You Work On Less Than 6 Hours Of Sleep

HuffPost  online

2019-05-03

If you’re in charge of others at work, it is imperative for you to get enough rest to be a good manager. A 2017 study led by management researchers Cristiano Guarana and Christopher Barnes measured the sleep of 40 managers and their 120 direct reports and the quality of the relationships between them during the first three months of working together.

Fatigue and Complacency: The Bane of Inspiration and Innovation

Innovation Excellence  online

2018-06-07

Oftentimes, when overworked or burnt out, employees and managers find themselves losing sleep and drowning in poor attitudes. In fact, HBR just published research showing that sleep deprivation has a compounding effect on your attitude about work.

“We start from the premise that sleep deprivation would make leaders and followers experience more negative emotions at work (in the form of hostility),” write Cristiano Guarana and Christopher M. Barnes. “You can probably easily remember a time in which you had a short night of sleep and had a bit of a short temper at work the next day. This is a very common experience and is largely driven by the fact that sleep deprivation undermines the parts of your brain involved in regulating emotions”...

Research: Sleep Deprivation Can Make It Harder to Stay Calm at Work

Harvard Business Review  online

2017-08-21

When new managers and their employees meet for the first time, they begin to forge their working relationship, which will be a crucial factor in how they both experience work, how much they trust each other, and how effectively they can work together. You may have a direct report that you hold in high regard, whom you give the most important tasks to, and spend the most time mentoring.

Sleep-Deprived Judges Dole Out Harsher Punishments

Harvard Business Review  online

2017-02-15

We all want to believe that we are fair judges, and that we would be objective when allocating such measures. However, there’s an important factor that could undermine your ability to be fair: sleep. My colleagues — Kyoungmin Cho at the University of Washington and Cristiano Guarana at the University of Virginia — and I wanted to investigate this link. My previous research indicates that sleep deprivation impairs ethical judgment and behavior. And the research literature indicates that sleep deprivation leads to errors in decision making that the decision makers are oblivious to. As I discuss in my TEDx talk, sleep-deprived people are impaired without even being aware that they are impaired...

Research: Sleep-Deprived Leaders Are Less Inspiring

Harvard Business Review  online

2016-06-15

There are two sides to the charismatic leadership coin: the leader and the follower. In my newest research (conducted with Cristiano L. Guarana, Shazia Nauman, and Dejun Tony Kong), I examine how sleep deprivation can undermine both sides of that coin. Our focus is on the role that emotions play in charismatic leadership...

The race discipline gap: A cautionary note on archival measures of behavioral misconduct Organizational Behavior and Human Decision Processes

2020

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.

Do not like it when you need it the most: Examining the effect of manager ego depletion on managerial voice endorsement Journal of Organizational Behavior

2019

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.

Archival research: Expanding the methodological toolkit in social psychology Journal of Experimental Social Psychology

2018

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 tools for conducting social psychological research.

Building sense out of situational complexity: The role of ambivalence in creating functional leadership processes Organizational Psychology Review

2014

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.
