1
Damage causes inability to plan and organize, leading to poor decision making (impulsive)
PFC
2
May impact muscle tone in lower face on one side
Hemispheric stroke
3
Is implicit or explicit deception detection better?
Implicit
4
What two pathways control facial expression?
Voluntary and spontaneous/involuntary
5
Contributes to social behavior. Damage may be implicated in sociopathy
Anterior cingulate cortex
6
What do patients with amygdala problems show that many autism patients show?
Difficulty figuring out emotions from facial expressions. Focus their eyes on the nose and not between eyes
7
Contains benzodiazepine (GABA) receptors (anxiolytics)
Amygdala
8
What cant Parkinsons patients show very well and why?
Joy. They have damage to their basal ganglia which impairs the spontaneous pathway of expression
9
More active brain areas during truth
Inferior parietal lobe
10
James-lange theory pathway
Thalamus to limbic system to bodily reaction to cortex
11
Examples of universality of emotions
Major expressions same across diverse cultures. Stranger anxiety at same age (9 months). Blind infants and sighted infants exhibit emotional expressions at the same time (2 months)
12
Receives only contralateral input
Lower 2/3 of face
13
Damage here produces emotional disturbance
Frontal lobe
14
How are specific emotions located in the brain?
Widespread areas of the brain are associated with specific emotions
15
What are the 2 continuum's emotion lies on?
Valence and arousal
16
Physiological arousal contributes to emotions intensity, while identity of emotion is based on cognitive appraisal
Schachter-Singer Two Factor theory of emotion
17
Measure of sweat gland activation, sympathetic nervous system activity
Skin-condunctance response
18
More active brain areas during lies
Inferior and medial frontal gyrus
19
Associated with disgust and pain
Insula
20
High activity in people with anxiety disorders
Anterior cingulate cortex
21
This hemisphere plays a greater role in expression and perception of emotion
Right
22
What does Yerkes-Dodson law say?
There is an optimal level of arousal that leads to the greatest performance. Like music being used to hype up or calm down before a game to hit that level
23
When is the amygdala more active?
When viewing facial expressions of fear
24
Action before emotion. Our emotional reaction is determined by our interpretation of the physical response
James-Lange theory
25
Lesion of amygdala
Difficulty identifying fear and anger
26
Damage to these causes individuals to not respond emotionally to poor choices. No regret for poor choice
Orbitofrontal and ventromedial cortexes in the PFC
27
Positive or negative emotions. Good and want more or bad and want less
Valence
28
Kluver-bucy syndrome that affects this area causing reduced fear
Amygdala
29
What improves the ability to detect deceit?
Feeling threatened. High stakes.
