positive impacts

• witnessing a stressful event creates anxiety through physiological arousal within the body
• fight or flight response is triggered increasing alertness which may improve memory for the event as we become more aware of cues in the situation
• a supporting study is Yerkes-Dodson Law
• Yerks and Dodson law says that stress is related to performance and the relationship between emotional arousal and performance looks like an inverted U
• yerkes and dodon interviewed 21 cases of EWT and noted that low levels of anxiety had lower levels of anxiety and high level of anxiety had higher levels of recall accuracy
