Q

What were the medical practices of the ancient Greeks and Romans based on?

A

Body had 4 elements (earth, air, water, fire) served by 4 humours (blood, phlegm, yellow bile, black bile).

The humours had to be correctly balanced to prevent becoming ill

  2. Turned away from holism and connectionism
27
Q

  1. Diaschisis
  2. Compensation
  3. Individual differences, different brains
  4. Interfering impairments
  5. Poorly developed concept of localization of function
29
Q

What is holism?

A

The idea that everything is integrated and connected

30
Q

What was the case of patient HM?

A

He suffered from severe epilepsy. He couldn’t make new memories. This indicated semantic memory is independent of episodic memory

31
Q

What is the idea of compensation in the brain?

A

Other brain areas compensate for damaged areas with different strategies

32
Q

What is diaschisis? What are 3 widespread effects of brain injury?

A

A brain region that is intact shows changes in functioning as a result of connections to a lesioned brain region. So a lesion can have more widespread effectis

  1. Connections
  2. Synchronisation difficulties affecting communication
  3. Organization differences that influence information processing streams
33
Q

What does it mean to have individual differences concerning neuropsychology?

A

There is a lot of variation in typical brain anatomy and physiology

34
Q

What are 4 aspects of the dark history of neuropsychology?

A
  1. Experimentation without consent
  2. Using experimental medical procedures
  3. Racial and class judgment
  4. Misuse of assessments
35
Q

What are 4 ways to ensure we’re doing better in the future?

A
  1. Informed consent and independent ethical review
  2. Monitore guidelines for introducing new treatments
  3. More inclusive research
  4. Incorporating theories from other disciplines and cultures
36
Q

What has always been an important question in the brain-behavior debate?

A

Localization: where is the soul or mind, which organs play a role in the mind affecting the body

37
Q

What were the 3 different forms of soul according to the ancient Greeks?

A
  1. Survival via food (plants
  2. Activities of organism in relation to environment (animals)
  3. Higher order soul that can distinguish between good and bad (humans)

People were the only beings who had all three forms of soul

38
Q

Where was the soul according to Plato and Hippocrates? And according to Aristotle?

A

In the brain

Aristotle: in the heart

39
Q

What did philosophers that studied anatomical structure in the ancient time think about the ventricles?

A

The ventricles were called cells and it was thought the mind was located there

40
Q

What are the different functions of the mind according to the cell theory of the mind (ancient period)?

A
  1. Receive info from the senses
  2. Interpret image –> what does it mean and how important is it for me
  3. Memory
41
Q

How is the cell theory of the mind still aplied in current cognitive psychology?

A
  1. General system of info processing: no separate functions for different stimuli or knowledge
  2. Theory doesn’t consider individuals but describe mental processes in general
42
Q

What did Aristotle mean with Physiognomy?

A

The interpretation of the face: a shape of one’s face was regarded as a reflection of their character

43
Q

Where did Descartes think the mind was located?

A

Cavity in the middle of the head: pineal gland

44
Q

Why did Gall’s perspective break with the earlier idea of a soul and an undivided mind?

A

Gall proposed independent functions. So all functions had their own location on the brain surface that could be measured by mapping skull bumps

45
Q

What is the clinico-anatomical method?

A

Correlating symptoms and patterns of behavior presented throughout life to brain lesions discovered post-mortem. Based on the assumptions of differentiation and localization

Used by Charcot and later Wernicke and Broca

46
Q

What is empiricism by John Locke?

A

Don’t believe in innate characteristics. Everythin was learned and learning was accomplished through the principle of association

47
Q

What is the Gestalt movement?

A

Espouses the view that the whole is greater than the parts

48
Q

What is the opposite of locationalism?

A

Holism

49
Q

Who discovered language was mainly left hemispheric?

A

Broca

50
Q

Who sought a balance between holistic an locationalistic views?

A

Luria: brain is a single complex functional system within which various subsystems contribute to joint activity

51
Q

What are Luria’s 3 broad classifications?

A
  1. 3 interacting functional units
  2. 3 hierarchically organized levels of processing
  3. Behavior that isn’t/is regulated by language processes related to left or right hemisphere
52
Q

What are three assumptions in phrenology that are still used nowadays?

A
  1. Localization of function
  2. Differentiation of function
  3. Mental abilities originate in the brain
53
Q

Who are the diagram makers and when were they active?

A

Diagram makers were a group of scientists in 19th/20th century. They created detailed diagrams of brain structure and function assuming localization and differentiation of function

54
Q

What were the 2 types of visual agnosia according to Lissauer? What kind of dissociation is this and what does that imply?

A
  1. Apperceptive: poor internal description of outside world (impaired perception)
  2. Associative: object perceived, but unable to relate the image to info stored about that object

Single dissociation: implies sequential process, so differentiation of function

55
Q

What did Wilbrand and Dejerine discover concerning object recognition?

A

They saw a double dissociation in their patients
- One could recognize objects, but wasn’t able to read
- One couldn’t recognize objects, but was able to read

This indicated a parallel process

56
Q

What did Lashley (1950) mean with the concept that the brain functions through mass action?

A

A concept suggesting that the brain functions as a coordinated whole

57
Q

What is Fodor’s (1983) theory of modularity and what are it’s 4 characteristics? Where does the theory come from?

A

A module:
1. Is domain-specific
2. Has innateness
3. Is encapsulated
4. Has a fixed neural architecture, not sharing processes with other modules

Fodor believes, like Chomsky, that language ability is an innate specific property. We have no awareness of these language processes and don’t control is. Therefore language is a module

58
Q

Why did David Marr (1982) play a crucial role in theory development in cognitive neuropsychology?

A

He proposes that the functions of the brain could also be performed by computers.

The brain is a collection of neural networks and connectionist models can conceptualize cognitive function in the form of input leading to activity and then to output

59
Q

What are 3 principles of neural network connectionist models (Marr)?

A
  1. Emergence of properties: if a property exists, it’s becaus it has emerged from the model itself and not that it existed innately (model can teach itself)
  2. Graceful degradation: if damage occurs, the model won’t completely stop working, but it functions with missing info
  3. Content addressability: a small amount of info can activate an entire trace
60
Q

What is the cause of diaschisis?

A

Changes in the stream of processing caused by the brain’s attempt to adapt or by metabolic changes. This causes a lesion in one location to have more widespread effects

61
Q

What do we mean with interfering impairments as a lesson learned from the past?

A

Certain cognitive deficits may impair other cognitive functions due to dependence of functions.

E.g. someone with visual perceptual deficit may have visual attention problems as well

62
Q

What do we mean with poorly developed concept of function localization as a lesson learned from the past?

A

There is still no consensus over a theoretical framework for localization of function in the brain.

63
Q

What are the 3 main concepts that are proposed for a theoretical framework for localization of function?

A
  1. Modules
  2. Networks
  3. Mass action
