Q

Name the indirect effects of adrenaline

A

Prepares the body for fight or flight, Increases blood supply to skeletal muscles for physical action, Stops digestion and saliva production, Increases oxygen to the brain for rapid response planning

Q

What does ‘befriend’ in tend and befriend mean?

A

Form alliances with other women

19
Q

Fight or flight might not be the only two responses. What is the other potential response?

A

Freeze

20
Q

Why might people freeze when confronted with danger?

A

Freeze to consider the best course of action for the stressor they are faced with

21
Q

What two systems play a major role in producing the fight or flight response?

A

Autonomic Nervous System (ANS) and the endocrine system

22
Q

When would the sympathetic branch of the Autonomic Nervous System be activated?

A

When a stressor is identified by the brain

23
Q

When a stressor is identified by the brain, which branch of which nervous system is activated?

A

Sympathetic branch of the Autonomic Nervous System (ANS)

24
Q

What is the role of the hypothalamus in the fight or flight response?

A

Identifies a stressor

25
Q

When would the pituitary gland be activated in the fight or flight response?

A

After a stressor is identified by the hypothalamus

26
Q

Once the pituitary gland has been activated in the fight or flight response, what is triggered and where?

A

Activity in the sympathetic branch of the Autonomic Nervous System (ANS)

27
Q

Where is adrenaline released into?

A

The bloodstream

28
Q

Where is adrenaline released from during the fight or flight response?

A

The adrenal medulla

29
Q

When the fight or flight response is produced, what is the body prepared for?

A

Sudden physical action

30
Q

Increased heart rate, blood pressure and respiration and reduced saliva production and digestion are examples of…

A

Physiological reactions produced during the fight or flight response

31
Q

Give three physiological reactions that are produced during the fight or flight response

A

Increased heart rate, Increased blood pressure, Increased respiration
Reduced saliva production, Reduced digestion

32
Q

What type of response is the fight or flight response?

A

Immediate and automatic

33
Q

Which branch of which nervous system returns the body back to normal once the stressor has been removed?

A

Parasympathetic branch of the Autonomic Nervous System (ANS)

34
Q

The parasympathetic branch is involved in homeostasis, what does this mean?

A

It returns the body to a level of balance/back to normal once the stressor has been removed

35
Q

Give two examples of how the body is returned back to normal by the parasympathetic branch

A

Heart rate decreased, Respiration decreased, Digestion increased

36
Q

When adrenaline travels through the bloodstream, what does it activate that leads to an increase in heart rate and blood pressure?

A

The heart and circulatory system

37
Q

What is the main function of the parasympathetic branch of the Autonomic Nervous System (ANS)?

A

To activate the “rest and digest” response and return the body to homeostasis after the fight or flight response

38
Q

Why might the fight or flight response not explain the stress response in females?

A

Research has found women are more likely to protect their offspring (tend) and form alliances with other women (befriend) than to fight or run away

39
Q

Research has found women are more likely to protect their offspring (tend) and form alliances with other women (befriend) than to fight or run away.

What does this suggest about the fight or flight response?

A

There is a gender (beta) bias, as the fight or flight response assumes that men and women respond in the same way to a threatening situation

40
Q

State two issues with the fight or flight response

A

It does not explain the stress response in females
Human behaviour is not limited to two responses

41
Q

Rather than fight or flight, what do psychologists argue is the first response to danger?

A

To avoid confrontation altogether through a ‘freeze’ response

42
Q

Why is it suggested that the flight or flight response does not consider other factors such as thought processes?

A

People may freeze as a response to consider the best course of action for the threat they are faced with

43
Q

Some psychologists argue that the first response to danger may instead be to freeze and consider the best course of action.

What does this suggest about the fight or flight response?

A

It does not consider other factors such as thought processes
