To what extent are research results influenced by subjective decisions that scientists make as they design studies? Fifteen teams independently designed studies to answer five original questions related moral judgments, negotiations, and implicit cognition. Participants from 2 separate large samples (total N > 15,000) were then randomly assigned complete 1 version of each study. Effect sizes varied dramatically across different sets materials test the same hypothesis: Materials rendered...
This crowdsourced project introduces a collaborative approach to improving the reproducibility of scientific research, in which findings are replicated qualified independent laboratories before (rather than after) they published. Our goal is establish non-adversarial replication process with highly informative final results. To illustrate Pre-Publication Independent Replication (PPIR) approach, 25 research groups conducted replications all ten moral judgment effects last author and his...
People have fundamental tendencies to punish immoral actors and treat close others altruistically. What happens when these collide—do people or protect who behave immorally? Across 10 studies ( N = 2,847), we show that consistently anticipate protecting commit moral infractions, particularly highly severe acts of theft sexual harassment. This tendency emerged regardless gender, political orientation, foundations, disgust sensitivity was driven by concerns about self-interest, loyalty, harm....
The extent to which self-regulatory tendencies predict military leadership ability is unknown. In the present study, we assessed relationship between these and competency. During a United States Army (USA) Reserve Officer Training Corps (ROTC) Advanced Camp capstone leader development assessment course, 234 cadets completed survey measuring five tendencies: self-control, cognitive reappraisal, emotional suppression, grit, temporal self-distancing. Overall camp performance scores were used...
Previous research has established the role of positive emotional cultures such as companionate love and joy in predicting team performance. Building on this work, present study analyzes culture variables predictors resilient performance by examining patterns objective U.S. Army tank crews over time. We also broaden domain investigating an action-oriented optimism a negative anger. During high-stakes international military training exercise, 55 (N = 175) completed pre-qualification event,...
Abstract Experimental sleep restriction and deprivation lead to risky decision-making. Further, in naturalistic settings, short duration poor quality have been linked real-world high-risk behaviors (HRB), such as reckless driving or substance use. Military populations, general, tend less poorer than nonmilitary populations due a number of occupational, cultural, psychosocial factors (e.g. continuous operations, stress, trauma). Consequently, it is possible that insufficient this population...
Does stepping back to evaluate a situation from distanced perspective lead us be selfish or fair? This question has been of philosophical interest for centuries, and, more recently, the focus extensive empirical inquiry. Yet, extant research reveals puzzle: some studies suggest that adopting will produce rationally self-interested behavior, whereas others it impartial behavior. Here we adjudicate between these perspectives by testing effects third-person on decision making in task pits...
Loyalty has long been associated with being moral and upstanding, but recent research begun documenting how loyalty can lead people to do unethical things. Here we offer an integrative perspective on its outcomes. We suggest that a variety of bottom-up top-down psychological processes individuals be loyal organizations they have obligations to, these operate in ways reduce the cognitive dissonance experienced when loyalties conflict each other or principles. In this article, articulate what...
AbstractThe US Army launched the Global Assessment Tool (GAT) – a 105-item psychometric instrument taken by approximately one million soldiers annually in October, 2009 support of population-wide resilience development initiative known as Comprehensive Soldier and Family Fitness (CSF2) program. The lead developer GAT was Chris Peterson, his work on this project along with that Nansook Park Colonel Carl Castro will likely leave an important indelible mark not only Army, but also field...
Rates of suicide in the US Army continue to rise, and by some accounts exceed general population. This increase has renewed efforts identify protective factors that may inform novel prevention strategies. Previous research demonstrated a sense purpose life perceived cohesion with military peers are related reduction severity suicidal ideation (SI). Additionally, samples supports decreased SI Soldiers who endorse their leaders convey meaning shared mission. However, no work investigated...
Abstract Background The Walter Reed Army Institute of Research (WRAIR) Operational Kit-Actigraphy (WORK-A) is a set unique practice parameters and actigraphy-derived measures for the analysis operational military sleep patterns. WORK-A draws on best practices from literature comprises 15 additional descriptive variables. Here, we demonstrate with sample United States Reserve Officers’ Training Corps (ROTC) cadets ( n = 286) during month-long capstone pre-commissioning training exercise....
Abstract Although previous studies have identified behavioral health risks associated with combat exposure, it is unclear which types of events are these risks, particularly regarding contrasts among the life‐threatening experiences, killing combatants, and exposure to unjust war events, such as a noncombatant or being unable help civilian women children. In present study, we examined surveys from 402 soldiers following deployment (i.e., baseline) again 13 months later Year 1). Regression...

We aimed to assess the relationship between subjective sleep quality and occupationally-relevant outcomes in military personnel. Participants were from an elite unit of US Army soldiers who worked extended (~30 h) shifts (with minimal recovery time shifts) during 3-week work sessions. Questionnaires assessing month prior (Pittsburgh Sleep Quality Index [PSQI]) administered at beginning session. Occupational (emotional exhaustion, functional impairment, role overload, daytime sleepiness)...
Abstract We present the data from a crowdsourced project seeking to replicate findings in independent laboratories before (rather than after) they are published. In this Pre-Publication Independent Replication (PPIR) initiative, 25 research groups attempted 10 moral judgment effects single laboratory’s pipeline of unpublished findings. The were investigated using online/lab surveys containing psychological manipulations (vignettes) followed by questionnaires. Results revealed mix reliable,...
ABSTRACT Introduction Musculoskeletal injuries and insufficient sleep are common among U.S. Army Rangers. There has been limited research into whether indices of differ between injured uninjured The purpose this study was to investigate the association self-reported musculoskeletal injury in Materials Methods A total 82 Rangers (male, 25.4 ± 4.0 years) were asked if they currently have any injuries; completed Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity (ISI), Stanford Sleepiness...
US military service members have characteristically poor sleep, even when 'in garrison' or at one's home base. The physical sleeping environment, which is often in military-provided housing barracks, may contribute to sleep quality soldiers. current study aimed assess whether the environment garrison related quality, insomnia risk and readiness.Seventy-four army special operations soldiers participated a cross-sectional study. Soldiers were queried on their surface comfort frequency of being...
