M. A. Van Selst, E. Ruthruff, and J. C. Johnston (1999) found that practice dramatically reduced dual-task interference in a Psychological Refractory Period (PRP) paradigm with 1 vocal response and 1 manual response. Results from 3 further experiments using the highly trained participants of M. A. Van Selst et al. (1999) support 4 main conclusions: (a) A processing bottleneck exists even after ...

The apparently deleterious effect of aging on dual-task performance is well established, but there is little agreement about the source of this effect. Studies of the psychological refractory period (PRP) indicate that young adults can flexibly control dual-task performance through task-coordination strategies. Thus, the performance of older adults might differ from young adults because older a...

Why is the human brain fundamentally limited when attempting to execute two tasks at the same time or in close succession? Two classical paradigms, psychological refractory period (PRP) and task switching, have independently approached this issue, making significant advances in our understanding of the architecture of cognition. Yet, there is an apparent contradiction between the conclusions de...

The course of severe coronavirus infection is accompanied by hypercoagulability with micro- and macroangiopathy, which may be the cause arterial venous thrombosis. In March, 2021 — May 2021, 14 patients COVID-19 acute ischemia lower extremities due to thrombosis were operated in Infectious Pavilion N.V. Sklifosovsky Research Institute for Emergency Medicine. Retrombosis immediate postoperative ...

UNLABELLED The aim of the study was to evaluate the clinical spectrum of emergency surgery for acute abdominal disorders and their outcome. MATERIAL AND METHODS The study group comprised 1426 patients, aged between 10 and 92 years subject to emergency surgery, due to an acute abdomen during the period 2001-2004. Analysis comprised age, sex, concomitant diseases, ASA scale classification, post...

OBJECTIVE One of the most important and basic variables in emergency department (ED) operations is patient visit volumes. This variable is usually predicted on the basis of the average ED patient visit volume over a certain period. However, ED patient visit variability is poorly understood. Therefore, we evaluated ED patient visit variability in order to determine if the average can be used to ...

OBJECTIVES The purpose of this study is to determine the impact of the expected increase in the volume of patient visits in the emergency department during holiday periods on physicians' tendencies regarding test and consultation requests as well as on the length of time patients stay in the emergency department. METHODS The study groups included all of the patients who visited the emergency ...
