Choking under pressure in sport has been explained by either explicit attention to skill execution (self-focus theories), or attention to performance worries (distraction theories). The aim of the present study was to find out which focus of attention occurs most often when expert athletes perform under pressure. Two retrospective methods were employed, namely, verbal reports and concept mappin...

We extend previous work examining the effects of pressure on category learning to the effects of pressure on categorization performance in highly trained individuals. After extensive training on either a rule-based or an information-integration classification task, half of the participants performed the same task on a fifth day while under pressure to earn a monetary bonus ($50) for themselves ...

The ice sheets of Greenland and Antarctica are losing ice at accelerating rates, much of which is a response to oceanic forcing, especially of the floating ice shelves. Recent observations establish a clear correspondence between the increased delivery of oceanic heat to the ice-sheet margin and increased ice loss. In Antarctica, most of these processes are reasonably well understood but have n...
