Q

What is the difference between cortical and subcortical?

A

The cortex is where many of the higher-level functions take place (e.g. decision-making and language)

‘Subcortex’ means ‘beneath the cortex’. The subcortex is where we process more primitive functions (e.g. emotion processed in the amygdala).

32
Q

Panksepp has offered a functional definition of an emotional system. The first four emotion systems that appear shortly after birth are:

A
  1. Seeking
  2. Fear
  3. Rage
  4. Panic
33
Q

According to Panksepp there are 3 special-purpose systems developing at different stages, what are those emotions systems? (following seeking, fear, rage and panic)

A
  1. Lust
  2. Care
  3. Play
34
Q

The … system is a neural system for avoiding pain or injury. It is based in the central and lateral nuclei of the amygdala and responds to stimuli arriving from the thalamus

A

Fear system

35
Q

LeDoux has labelled the two sensory input pathways to the amygdala as …?

A

Low and high road

36
Q

LeDoux: this road (low or high) is only capable of low spatial resolution of stimuli and can respond to only simple stimuli or gross characteristics of complex stimuli

A

Low road/thalamus-amygdala

37
Q

LeDoux: this road is more influenced by social and personal decision-making processes and can reflect culture-specific emotional responses

A

High road/ thalamus-sensory cortex-amygdala

38
Q

… neglect is a deficit in body perception and visuospatial processing in individuals who have lesions in their parietal cortex

A

Parietal (damage to the temporo-parietal junction and posterior parietal cortex)

39
Q

What do we call it, when two different stimuli are presented simultaneously in the right and left visual field and patients with right neglect will report not being able to see the stimulus in their left visual field

A

Extinction

40
Q

According to results form Vuilleumeir’s study, something activated the amygdala in patients with right hemisphere parietal damage. Even when the stimuli was on the neglected side. What was it?

A

Fearful faces

41
Q

What do we call the ability to react in behaviourally appropriate ways to specific objects without awareness of the stimuli?

A

Blindsight (a phenomenon in which patients with damage in the primary visual cortex of the brain can tell where an object is although they claim they cannot see it)

42
Q

What do people with bilateral amygdala damage fail to look at?

A

The eyes when judging facial expression

43
Q

What receptors are activated with extinction (the gradual weakening of a conditioned response = Pavlovian)?

A

NMDA receptors in the amygdala (play a role in triggering the neural changes that support fear learning and also the loss of fear that accompanies extinction training)

When activation in enhanced, extinction is increased

44
Q

Memories become permanent through a process of protein synthesis, what is this called?

A

Consolidation

45
Q

What kind of coping strategies do people use?

A
  1. Reappraisal (looking more positive at things)
  2. Reinterpretation
46
Q

Panksepp described the SEEKING system with two primary reward pathways, which are those?

A
  1. Mesolimbic dopamine pathway (rewarding effects of drugs and foods)
  2. Mesocortical dopamine pathway (cognitive control, motivation, and emotional response)
47
Q

Dopamine neurons respond more to predicted/unpredicted rewards (reward prediction error theory)

A

Unpredicted

Reward prediction error theory: the response to the reward itself disappears when the reward is predicted

48
Q

What are the three components of the reward prediction theory?

A
  1. Liking
  2. Learning
  3. Wanting
49
Q

Natural rewards and abuse of drugs act in different ways on the … dopamine system

A

Mesolimbic

50
Q

Which component theory did James-Lange come up with?

A

Physiology drives processes

(physical changes in the body happen first, which then leads to the experience of emotion. Emotions stem from your interpretation of your physical sensations)

51
Q

Which component theory did Cannon come up with?

A

Cognition drives processes

(stimulating events trigger feelings and physical reactions that occur at the same time)

52
Q

Which component theory did Strack et al. come up with?

A

Expression drives processes

(people’s affective responses can be influenced by their own facial expression (e.g., smiling, pouting), even when their expression did not result from their emotional experiences)

53
Q

Who invented the dimension model (valence and arousal)?

A

Russell

Each affective state can be represented by two dimensions: arousal and valence
Arousal indicates the level of a person’s involvement in reaction to a stimulus
Valence defines the positive or negative state in response to a stimulus. High values of valence = pleasant situations, low values = unpleasant

54
Q

What does the discrete system model entail and who uses it?

A

Small set of basic emotions (seeking, rage, fear, panic, lust care and play)
Panksepp

55
Q

Which three core components are there within emotion?

A
  1. Physiological arousal
  2. Expression
  3. Subjective feeling
56
Q

What do we call an emotion that can last for days, weeks or months?

A

Mood

57
Q

What do we call an emotions that lasts a lifetime?

A

Personality trait

58
Q

Who argues that the emotional system is an emergency system that can take action, to quickly select a new operative schedule. Is based on modules (automata) that automatically generises signals and triggers a response

A

Oatley & Johnson-Laird

59
Q

Emotional responses are determined by what? (subcortical and neocortex)

A
  1. Classical conditioning for stimuli that were thus previously linked to pleasure/pain (subcortical)
  2. Cognitive perception of stimuli in certain context (neocortex)
60
Q

What did reseachers conclude in affective blindsight studies? (ability of such patients to respond correctly to visual emotional expressions presented to their blind fields)

A

That recognition of fear is mandatory and independent of awareness. So fearful faces can be processed without awareness despite the damage

61
Q

What do we call a behavior conditioning method that presents the stimuli in a reverse order, that is, the unconditioned stimulus (US) occurs before the neutral stimulus (NS)?

A

Reverse conditioning

62
Q

What produces more dopamine? The anticipation or the receiving of the reward?

A

The anticipation of reward

63
Q

The hedonic feeling of (liking/wanting/learning) is dissociable from the dopamine system

A

Liking (likeability appears to depend on a separate system involving the shell of the nucleus accumbens)

64
Q

Which drug inhibits reuptake and which drug increases dopamine release?

A

Cocaine inhibits reuptake and amphetamine increases release

65
Q

What are the 3 components of expectancy theory (in between the stages effort, performance, outcome, motivation)?

A

The expectancy theory hinges on three elements:
1. Expectancy
2. Instrumentality
3. Valence

66
Q

What is the emphasis of the classical motivation and reward theory?

A

Maintaining homeostasis/physiological balance

Drive theory: states that deviations from homeostasis create physiological needs that result in psychological drive which results in direct behavior to meet the need and ultimately bring the system back to homeostasis

67
Q

What is a N-back task?

A

N-back tasks involve the continuous sequences of stimuli (e.g., images or letters), presented one-by-one in which participants must determine if the currently presented stimulus is the same as the stimulus presented n trails before (e.g., 1, 2, or 3)

Measures working memory and working memory capacity

68
Q

What did the reward modulated n-back test from Thurm concluded?

A

Better memory if reward is better

69
Q

What is anhedonia?

A

Lack of pleasure

70
Q

Motivation/pleasure is mostly implemented in frontal cortical areas that receive input from subcortical areas

A

Pleasure
