The impact of the COVID-19 pandemic on European police officers: Stress, demands, and coping resources

Purpose: Facing the COVID-19 pandemic, police officers are confronted with various novel challenges, which might place additional strain on officers. This mixed-method study investigated officers’ strain over a three- month-period after the lockdown. Methods: In an online survey, 2567 police officers (77% male) from Austria, Germany, Switzerland, the Netherlands, and Spain participated at three measurement points per country in spring, 2020. Three-level growth curve models assessed changes in strain and its relation to stressor appraisal, emotion regulation, and pre- paredness through training. To add context to the findings, free response answers about officers’ main tasks, stressors, and crisis measures were coded inductively. Results: On average, officers seemed to tolerate the pandemic with slight decreases in strain over time. Despite substantial variance between countries, 66% of the variance occurred between individuals. Sex, work experience, stressor appraisal, emotion regulation, and preparedness significantly predicted strain. Risk of infection and deficient communication emerged as main stressors. Officers’ reports allowed to derive implications for governmental, organizational, and individual coping strategies during pandemics. Conclusion: Preparing for a pandemic requires three primary paths: 1) enacting unambiguous laws and increasing public compliance through media communication, 2) being logistically prepared, and 3) improving stress regulation skills in police training

The influence of anxiety on visual entropy of experienced drivers

This study tested the use of entropy to identify changes on behavior of drivers under pressure. Sixteen experienced drivers drove in a simulator wearing a head-mounted eye tracker under low- and high-anxiety conditions. Anxiety was induced by manipulating some psychological factors such as peer-pressure. Fixations transitions between AOIs (lane, speedometer and mirrors) were calculated through first-order transition matrix, transformed to Markov probability matrix and adjusted into the entropy equation. Drivers showed greater state-anxiety scores and higher mean heart rates following manipulation. Under anxiety, drivers showed higher visual entropy, indicating a more random scanning. The randomness implies into a poorer acquisition of information and may indicate an impaired top-down control of attention provoked by anxiety

The role of anxiety in perceiving and realizing affordances

Three experiments were conducted to examine the role of anxiety in perceiving and realizing affordances in wall climbing. Identical traverses were situated high and low on a climbing wall to manipulate anxiety. In Experiment 1, participants judged their maximal overhead reachability and performed maximal reaches on the climbing wall. Anxiety was found to reduce both perceived and actual maximal reaching height. In Experiment 2, participants climbed from right to left and back again on the high and low traverses, which now entailed an abundance of holds. Consistent with the reduction of perceived and actual maximal reaching height found in Experiment 1, anxiety led to the use of more holds. Finally, in Experiment 3, points of light were sequentially projected around the participants while they were climbing to measure attention. As participants detected fewer lights in the high-anxiety condition, it was concluded that anxiety narrowed attention. In general, the results underscored that the actor's emotional state plays an important role in perceiving and realizing affordances and that the perception of affordances changes as the accompanying action capabilities change.

Issues and challenges in developing representative tasks in sport

"About the Book Understanding and developing expertise is an important concern for any researcher or practitioner working in elite or high performance sport. Whether it's identifying talented young athletes or developing methods for integrating cutting-edge sport science into daily coaching practice, scientists, coaches and researchers all need to understand the skills, characteristics, and knowledge that distinguish the expert performer in sport. The Routledge Handbook of Sport Expertise is the first book to offer a comprehensive overview of current research and practice in the emerging field of sports expertise. Adopting a multi-disciplinary, multi-faceted approach, the book offers in-depth discussion of methodological and philosophical issues in sport expertise, as well as the characteristics that describe sporting ‘experts’ and how they can be facilitated and developed. Exploring research, theory and practice, the book also examines how scientists and practitioners can work together to improve the delivery of applied sport science. With contributions from many of the world’s leading researchers in expertise and skill acquisition in sport, the Routledge Handbook of Sport Expertise is important reading for any advanced student, researcher, coach or sport science support officer looking to better understand this cutting-edge topic.

The effect of ego depletion on distractibility

Athletes in a state of ego depletion do not perform up to their capabilities in high pressure situations (e.g., Englert & Bertrams, 2012). We assume that momentarily available self-control strength determines whether individuals in high pressure situations can resist distracting stimuli. In the present study, we applied a between-subjects design, as 31 experienced basketball players were randomly assigned to a depletion group or a non-depletion group. Participants performed 30 free throws while listening to statements representing worrisome thoughts (as frequently experienced in high pressure situations; Oudejans, Kuijpers, Kooijman, & Bakker, 2011) over stereo headphones. Participants were instructed to block out these distracting audio messages and focus on the free throws. We postulated that depleted participants would be more likely to be distracted and would perform worse in the free throw task. The results supported our assumption as depleted participants paid more attention to the distracting stimuli and displayed worse performance in the free throw task. These results indicate that sufficient levels of self-control strength can serve as a buffer against increased distractibility under pressure. Implementing self-control trainings into workout routines may be a useful approach (e.g., Oaten & Cheng, 2007)

Can you go the extra mile?:the effect of ego depletion on endurance performance

We tested the assumption, that individuals (N = 13 participants) would perform worse in a cycling endurance task and would invest less effort under ego depletion than with temporarily available self-control strength. Participants' self-control strength was experimentally manipulated (non-depletion vs ego depletion, order counterbalanced) in a within-subjects design (two points of measurement, 48 hours apart) before participants performed a 6 km time trial on an indoor track. Non-parametric bootstrapping revealed that ego depletion had the most obvious effect on power output and cycling times per lap at the beginning of the time-trial. The effect of ego depletion on revolutions per minute and heart rate was large in the early parts of the time-trial, faded somewhat during the middle, while it increased again towards the end of the time-trial. The current study suggests that it might be beneficial to develop strategies which help to replenish depleted self-control strength
