Decrements in performance on cognitive tasks resulting from pressure to perform (i.e., choking) are thought to be caused by interference with the ability to use explicit strategies (the distraction theory). This view suggests that pressure should improve tasks for which explicit strategies hamper performance. This hypothesis was tested by giving participants one of two nearly identical learning...

It is well-known that laminar flow of a liquid in a duct is predicted to choke if the viscosity of the liquid increases exponentially with increasing pressure. In other words, the pressure drop in the duct is predicted to become unbounded when the volumetric flow rate reaches a critical finite value. Choking is not observed in practice, however: the reason why is investigated here. It is shown ...

Furthermore, many other important hemostatic proteins of similar size are also pathologically excreted in the urine. The loss of antithrombotic factors in the urine is counterbalanced by an...
