29
Q

What improves the ability to detect deceit?

A

Feeling threatened. High stakes.

30
Q

How does music influence arousal?

A

Music can be used to hype up or calm down in order to reach optimum arousal

31
Q

Environmental influences on emotion

A

Presence of others influences intensity of emotional expression

32
Q

Damage causes apathy and loss of initiative or drive

33
Q

What can single brain regions do in emotion?

A

Participate in more than one emotional state

34
Q

Basal ganglia involved. Duchenne smile

A

Spontaneous/involuntary pathway of expression

35
Q

What does sweat tell us?

A

If there is an emotional response or not

36
Q

Specific pattern of autonomic arousal leads to specific emotions. Changes in body lead to changes in emotion

A

James-Lange theory of emotion

37
Q

This hemisphere is involved in avoidance

38
Q

What is significant about the PFC?

A

It has many inputs and outputs

39
Q

What is the gambling task?

A

Anticipating the bad deck and sweating in anticipation. Emotional responsivity

40
Q

What is the output to behavior in the limbic system?

A

Hypothalamus

41
Q

6 primary emotions

A

Disgust, fear, joy, sadness, anger, and surprise

42
Q

Controls the superficial muscles attached to the skin of the face

A

Cranial nerve VII (Facial)

43
Q

Distinguishes between positive and negative stimuli

44
Q

What does deception cause?

A

It has high cognitive costs and arousal produces physical clues of deceit

45
Q

Controls deep muscles attached to the bones of the head

A

Cranial nerve V (Trigeminal)

46
Q

Individual differences in emotion

A

Overall level of reactivity differs and temperament

47
Q

Schachter-singer theory pathway

A

Cortex to thalamus and limbic system to bodily reaction back to cortex. Early cortical activation

48
Q

What do areas of the brain associated with different emotions do?

49
Q

How are all of our emotions made?

A

A combination of primary emotions

50
Q

Involved in fear conditioning

51
Q

What are trusting people poorer at?

A

Detecting deceit

52
Q

Produces different patterns of arousal during different emotional states

A

Autonomic nervous system

53
Q

How does damage to the frontal lobe (orbitofrontal and ventromedial cortexes) influences the skin-conductance response?

A

The damage patients showed little to no sweat response

54
Q

This hemisphere is involved in approach

55
Q

Conscious, cognitive appraisals of threat

A

Anterior cingulate cortex

56
Q

Strong belief a loved one has been replaced by identical imposter. Caused by visual recognition with no emotional connection. No SCR, no arousal

A

Capgras delusion

57
Q

Where are the nuclei of the cranial nerves that control facial expressions?

A

Pons near the midline

58
Q

When does the ANS have a stronger response?

A

Negative states

59
Q

What is the Duchenne smile?

A

Genuine smile. Smile with eyes

60
Q

How were areas active during lies and truths found?

61
Q

Key structures of the limbic system

A

Cingulate gyrus, anterior thalamus, hippocampal formation, amygdala, mamillothalamic tract, hypothalamus

62
Q

What does the facial feedback hypothesis say?

A

Certain facial expressions send signals to the brain that can help lift a mood

63
Q

Receives bilateral input

A

Upper 1/3 of face

64
Q

Damage causes inability to experience and express emotions and to recognize emotions expressions of others

65
Q

Sensation + solve = emotion. Physical arousal caused by stimulus is labeled and associated with an emotion we then feel

A

Schachter-Singer theory

66
Q

Contralateral motor cortices involved (right or left). Forced or fake smile

A

Voluntary pathway of expression

67
Q

Level of emotions. High and intense or low and calm

68
Q

Stimulation of amygdala

A
