Stress response and memory

What was the main aim of McGaugh and Cahill's study?

• To study the role of emotion in the creation of memories

• To investigate the effects of beta-blockers on heart disease

• To explore the ecological validity of memory studies

• To examine the role of the hippocampus in memory formation

What physiological response is triggered by a traumatic event?

• The body's 'rest and digest' response

• The body's 'freeze' response

• The body's 'fight or flight' response

• The body's 'sleep' response

Which hormone is released from the adrenal gland during stress?

• Serotonin

• Insulin

• Dopamine

• Adrenaline

What role does the amygdala play in memory?

• It processes visual information

• It attaches emotional significance to stimuli

• It stores long-term memories

• It regulates sleep cycles

How many slides did participants view in McGaugh and Cahill's study?

• 10 slides

• 20 slides

• 15 slides

• 12 slides

What was the difference between the two stories told to participants?

• One was a fictional story, the other was a true story

• One was about a car accident, the other about a plane crash

• One was about a hospital visit, the other about a school trip

• One was emotionally arousing, the other was mundane

What was the purpose of using beta-blockers in the follow-up study?

• To increase heart rate

• To prevent activation of the amygdala

• To improve visual perception

• To enhance memory recall

What was the result of the follow-up study with beta-blockers?

• Participants experienced increased heart rates

• Participants recalled more details than the original study

• Participants had improved emotional responses

• Participants showed no difference in recall compared to the mundane story group

What conclusion did the researchers draw about the amygdala?

• It is not affected by adrenaline

• It is only involved in visual memory

• It plays a significant role in creating memories linked to emotional arousal

• It has no role in memory formation

What concern is raised about the study's ecological validity?

• The study used real-life traumatic events

• The study was highly controlled and artificial

• The study had a large sample size

• The study was conducted in a natural setting
