Positive if catastrophe theory
Considers both somatic and cognitive anxiety
Graph up to optimum
If somatic arousal increases so does performance up to optimum but only if cognitive anxiety is kept low
High cognitive anxiety combined with high somatic arousal
Performer goes beyond optimum point, loses concentration and sharp decline in performance
Performance after catastrophe
If arousal is controlled and lowered after performer goes over optimum, performance can improve and upward curve can be rejoined
If arousal increases after optimum further deterioration occurs
Negative of catastrophe theory
Doesn’t take into account types of skills
