Measuring arousal and anxiety

Measuring arousal requires looking at changes in physiological signs e.g. HR, respiration, skin conductance and biochemistry.

People can also rate their arousal with a series of statements.

To measure state or trait anxiety psychologists use global and multidimensional self-report scales. E.g. CSAI-2 is the cognitive state anxiety inventory version 2. SCAT is the sport competition trait anxiety test.
