Choking under pressure describes suboptimal sport performance in stressful situations, which has led to two fundamental 'choking' models: distraction and self-focus. The purpose of this review was to provide an overview of empirical studies that have tested interventions used to alleviate choking. The systematic review includes 47 empirical studies published up to April 2017, including experimental, quasi-experimental, and single-case studies with athletes. These studies encompassed a variety of interventions (n = 13) that were either distraction based or self-focus based. In addition, a third group -acclimatisation interventions -was identified. The results indicate that, in general, choking interventions based on both choking models and on acclimatisation provide a benefit to performance under pressure. The most reported effective interventions were pre-performance routines, quiet eye training, left-hand contractions, and acclimatisation training. The use of dual task was beneficial for performance under pressure but harmful when used in training. Mixed evidence was found for analogy learning, and null effects were reported for goal setting, neurofeedback training, and reappraisal cues. These results may help athletes and coaches select and implement effective strategies and methods to improve performance under pressure. ARTICLE HISTORY

The relationship between work-life balance (WLB) (i.e. the perceived sufficiency of the time available for work and social life) and well-being is well-documented. However, previous research failed to sufficiently explain why this relationship exists. In this research, the hypothesis was tested that a sufficient amount of the time available increases well-being because it facilitates satisfaction of personal needs. Using two separate samples (students and employees), the mediating role of need fulfilment in the relationship between WLB and well-being was supported. The results suggest that perceived sufficiency of the time available for work and social life predicts the level of well-being only if the individual's needs are fulfilled within that time.

When well-learned motor skills fail, such as when elderly persons fall or when athletes "choke under pressure," it is assumed that attention is directed toward the execution of the action. Research findings suggest that this controlled execution and subsequent inferior performance depend on a dominant left-hemispheric activation. In a series of 3 experiments, we tested whether increasing right-hemispheric activation by the use of hemisphere-specific priming extenuates motor skill failure. We compared the performances of a sample of experienced athletes in different sports (soccer, tae kwon do, and badminton) in a pressure-free situation with that performed under pressure. As expected, the hemisphere-specific priming extenuated a performance decrease after pressure induction when compared with a control condition. The results suggest that hemisphere-specific priming may prevent motor skill failure. It is argued that this hemispheric priming should be task dependent and can be understood as a functional regulation of the activation in the hemispheres.
