Chapter 2.8 - Factors affecting EWT: Anxiety Flashcards
What is meant by anxiety?
A state of emotional and physical arousal
- Emotions: worried thoughts and feelings of tension
- Physical: increased heart rate and sweatiness
Describe how anxiety has a negative effect on recall (weapon focus)
Anxiety creates a physiological arousal in the body which prevents us paying attention to important cues, so recall is worse
Describe the procedure on the research on how anxiety has a negative effect on recall (weapon focus)
Johnson and Scott (1976):
- Participants believed they were taking part in a lab study
- Low anxiety condition: overheard a casual conversation in the next room, man walked past carrying a pen and with grease on his hands
- High anxiety condition: overheard a heated argument in the next room, accompanied by the sound of breaking glass, man walked out of the room holding a knife covered in blood
Describe the findings on the research on how anxiety has a negative effect on recall (weapon focus)
- Man was picked out from a set of 50 photos, 49% identified pen man, 33% identified knife man
Describe the conclusions on the research on how anxiety has a negative effect on recall (weapon focus)
Tunnel theory of memory: argues that people have enhanced memory for central events
- Weapon focus as a result of anxiety can have this effect
Describe how anxiety has a positive effect on recall
Witnessing a stressful event creates anxiety through physiological arousal within the body
- Triggers the fight or flight response, increasing alertness
- May improve memory for the event as we become more aware of cues in the situation
