Q

Give two problems of behaviourism:

A
  • thoughts and strategies during problem solving etc could not be studied
  • Different stimuli elicit the same behaviour & same stimuli elicits different behaviour → ambiguity

Q

What is the problem with behaviourism considering language?

A

Structure of language is more complex than behaviourism can explain, children speak sentences they have never heard

Q

What did EP learn from introspection and behaviourism?

Q

What is the Amygdala?

A

Emotional evaluator, helps to detect which stimuli are a threat/danger or safety/reward. Damaged in people with Capgras syndrome makes them not recognised loved ones. Lies in the temporal lobe

Q

Give a definition of Capgras syndrome and what is damaged

A

Prefrontal cortex and amygdala is damaged. Results in patients thinking their loved ones are imposters. They recognise them, but don’t have the feeling that they are the loved ones. PFC does not filter out those thoughts.

Q

What does the midbrain?

A

coordinating (eye) movements, relay audio from ears to forebrain, pain experience

25
Q

What does the forebrain consists of?

A

Cerebrum, thalamus and hypothalamus

26
Q

What does the pituitary gland?

A

Part of endocrine system, secrete hormones in blood

27
Q

lateral fissure

A

divides frontal lobes from parietal lobes

28
Q

What lies underneath the cortex?

A

Subcortial structures (thalamus, hypothalamus etc)

29
Q

What is the thalamus

A

relay station for all sensory information, quite big

30
Q

What is the limbic system

A

surrounds the thalamus and hypothalamus, is the amygdala and hippocampus => essential for learning and memory

31
Q

What are commissures and what do they do?

A

Bundle of fibres carrying information between the hemispheres

32
Q

What are commissures and what do they do?

A

Bundle of fibres carrying information between the hemispheres

33
Q

In which hemisphere is language processing dominant?

A

Left side

34
Q

Which hemisphere is dominant for spatial judgement?

A

Right side

35
Q

Each hemisphere makes it own contribution to overall performance.

A

Each hemisphere makes it own contribution to overall performance.

36
Q

Define a lesion

A

a specific area of brain damage

37
Q

What is the difference between PET and CT, what is their frame and what is the difference with MRI?

A

CT is structural image, PET is activity. Both not real time and main difference is that MRI is more detailed.

38
Q

What does EEG measure?

A

current generated by neurons under the skull, multiple rhythms can be detected

39
Q

What is the fusiform area?

A

This is active whenever a face is perceived

40
Q

TMS

A

transcranial magnetic stimulation; used to determine what happens when (temporary) a lesion is in the brain, helps to determine functions of brain parts in neuroscience

41
Q

What do we gain from combining multiple methods?

A

Excluding correlational data; with fMRI and EEG know know where and when.

42
Q

Define contralateral control

A

Left hemisphere controls right side of the body and vice versa

43
Q

What is coding (in neurons) and give it’s two options

A

how information (example a picture) is represented by neurons, two options:

  • neurons X,Y&Z fire
  • X fires a little, Y strong, Z little
44
Q

What are motor areas

A

contain brain tissue for organising and controlling movement

45
Q

What are sensory areas

A

contains brain tissue for organising and analysing sensory input

46
Q

What area association areas

A

support functions (oa. thinking)

47
Q

What is coding (in neurons) and give it’s two options

A

how information (example a picture) is represented by neurons, two options:

  • neurons X,Y&Z fire
  • X fires a little, Y strong, Z little
48
Q

What is apraxia

A

disturbance in initialising and organising voluntary actions due to damaged frontal lobe

49
Q

What is agnosia?

A

(in)ability to identify familiar objects, due to damaged occipital cortex

50
Q

What is neglect syndrome?

A

due to damage in usually parietal love, individuals seem to ignore half the visual world

51
Q

What is Aphasia?

A

Less language capabilities, due to damage near lateral fissure

52
Q

What is and does the primary motor projection area?

A

departure point for nerve cells (that send their signal to lower portions of the brain and spinal cord), resulting in muscle movement

53
Q

What is and does the primary (soma)sensory projection area?

A

point of arrival for sensory information

54
Q

Assignment of cortical space is governed by:

A

function

55
Q

In neurons: axons are .. and dendrites are..

A

output - input

56
Q

What are glia cells

A

support cells of neurons

57
Q

What is in the end the focus of the cognitive revolution?

A

the science of psychology cannot study the mental world directly & psychology must study the mental world in order to understand behaviour

58
Q

What is the Stroop effect?

A

automaticity; apparently being unable to ignore the word’s content even though it is irrelevant to their task.
