Catastrophe theory of arousal
1. At low levels of arousal performance is poor as SA and CA are both low
2. As SA increases performance improves
3. Performance is at its best when CA is low and SA is high
4. If both SA and CA are high then performance drops dramatically
5. Performer can recover if CA levels are lowered (positive thinking) and performance starts to increase again
6. If a performer worries about a drop in their performance their CA increases further causing performance to deteriorate further
