Q

Simulation Theories

A

theory of mind is achieved through our ability to put ourselves in a person’s “mental” shoes and imagine/”simulate” what we would experience in a similar situation.

Q

Executive theories

A

theory of mind is dependent on our ability to inhibit (inhibitory control) including our own perspective when trying to attribute mental states to others.

Q

Simulation (mirror neurons)

A

the same neurons are activated whether we plan to execute an action ourselves and when we observe other people execute the same action.

Belief and intention is attributed to the person being observed.

Q

Mirror neuron activation

A

Through visual input, mirror neurons are activated by actions performed by another person.

Externally generated activity in motor neurons does not usually produce an action in the observer.

23
Q

Executive Theory of mind

A

(response suppression)

paying attention to behaviourally relevant stimuli. Comparing predictions based on internal and external stimuli

24
Q

Executive theory of mind and memory

A

Working memory

25
Q

Inhibitory control

A

(executive function)
Many of the same brain areas should be activated in tasks that require only inhibitory control (without false belief) and false belief tasks.

26
Q

Inhibitory control parts of brain

A

Right medial prefrontal cortex, Right TPJ, parts of prefrontal cortex.

27
Q

Types of empathy

A
  1. Emotional contagion (spread of emotion from one to another)
  2. Cognitive empathy (ability to cognitively engage in adopting another person’s POV in an effort to understand that person’s experience)
28
Q

Perception-action model (PAM)

A

model of when perceiving another person’s emotional state the representation related to that state as well as the actions related to it are triggered in your own brain

29
Q

Emotional systems of empathy

A

reliant on simulation (for emotional contagion)

30
Q

systems of cognitive empathy

A

modular and executive models of TofM are related to it

31
Q

Social pain vs physical

A

is similar (in certain ways) to physical pain. Demonstrated by looking at brain areas that are commonly activated during both physical and social pain

32
Q

Two dimensions of physical pain

A
  1. Perceptual dimension

2. Affective dimension

33
Q

Perceptual dimension of pain

A

detection of painful stimulus:

  • somatosensory cortex
  • insula
34
Q

Affective dimension of pain

A

The perceived unpleasantness of the pain inducing stimulus:

-(ACC) Anterior Cingulate Cortex

35
Q

Pain regulation

A

What is done to manage or cope with pain:

-Right Ventral prefrontal cortex (RVPFC)

36
Q

Social exclusion

A

situation in which a person is not permitted to participate in an activity with other people

37
Q

cyberball exp’t

A

video game designed to test emotional and neurological reactions to social exclusion

38
Q

Social pain/physical pain overlap theory (SPOT)

A

there are overlapping neural mechanisms for physical and social pain

39
Q

Separation distress

A

mechanism that may have evolved in mammals to keep the young close to maternal contact and care

40
Q

SPOT theory b

A

Physical pain (child) and in people with chronic pain is related to more social pain in response to separation from a caregiver and anxiety about the loss of support from loved ones, respectively

41
Q

SPOT theory revelations c

A

Increased social support reduces chronic physical pain

some drugs regulate both pain (physical and social)

42
Q

Neural alarm

A

(ACC) detects problem in environment. emits an attention-grabbing stimulus to warn and what to do about it. ACC monitors for conflicts and detects errors.

43
Q

Altruism

A

Giving or helping behaviour strictly for the good of others

44
Q

The joy of giving

A

showed to have the same neurobiological basis as different types of rewards; money, drugs and food

45
Q

psychopaths

A

people who generally show disregard for the well-being of others as well as a lack of guilt, empathy and remorse

46
Q

Altruism (where)

A

Amygdala

47
Q

Reward brain areas___

A

activated by both walking away with monetary reward and by deciding to give

48
Q

Cooperation

A

the actions of individuals or groups in an effort to maximize their mutual benefits–cant ever be certain it is reciprocated (having common good in mind)

49
Q

Cooperation and trust

A

it may sometimes be perceived as advantageous to obtain help from others but to not reciprocate when that other person needs help

50
Q

Game Theory

A

A branch of mathematics devised to try to explain the behaviour of animals in nature and of people in social+political contexts.

51
Q

Prisoner’s dilemma

A

a game based on cooperation that shows that people’s decisions aren’t always based on rational thought:

  • cooperating (decision has mutual good in mind)
  • defecting (decision based on self interest)
52
Q

Trust game

A

a game based on trust in which an investor transfers a sum of money to a trustee with an expectancy of a return

53
Q

Most rewarding situation in prisoner dilemna (and where in brain)

A

Mutual cooperation (not the situation that resulted in the biggest payoff)

Activation in the brain areas associated with processing rewards:

  • Orbitofrontal cortex
  • Striatum
54
Q

Trust game (outcomes and imaging/areas)

A

used h-fMRI to investivate brain areas activated in game:

  • Benevolent
  • Neutral
  • Malevolent
55
Q

Trust game activation

A

benevolent>malevolent

56
Q

Trust game investors’ area

A

(MCC) Middle cingulate cortex

57
Q

Trust game trustees’ area

A

(ACC) Anterior cingulate cortex when learning about investors; decisions–indicating the trustees’ intention to trust investor

Caudate nucleus activity increased with the trustees’ decisions to trust the investor
