Q

what causes blindsight?

18
Q

psychodynamic perspective of dreaming

A

dreams have both latent content and manifest content

19
Q

biological perspective of dreaming

A
  1. dreams consist of random neural signals from the midbrain being interpreted by the cortex.
  2. dreams consolidate memories.
20
Q

blood pressure and pulse in REM sleep

A

increase

21
Q

REM sleep and brain activation

A

primary visual cortex is not activated but visual association areas in the occipital and temporal lobes are.

22
Q

james lange theory

A

bodily response preceeds emotion

23
Q

cannon bard theory

A

emotion inducing stimulus simultaneously elicits both emotional and bodily responses.

24
Q

common sense theory

A

feeling comes before the bodily experience.

25
Q

our imaginal representations of the world around us are referred to as

A

cognitive maps.

26
Q

types of cognitive maps

A

route maps and survey maps

27
Q

two-factor theory

A

bodily response occurs which we interpret (i.e. I am afraid because my heart is beating fast), which leads to the experience of emotion,

28
Q

frontal lobe damage

A

Located in the pre-frontal cortex.
Deficits may include:
- Disinhibition (wouldn’t be able to control himself).
- Emotional lability (reactive aggression)
- Change in personality
- Lack of empathy (would be bad at tracking the emotions and intentions of others)
- Diminished social insight
- Socially inappropriate behaviour, especially conversational skills
- Difficulties with changing reinforcements
- Lack of sensitivity to future outcomes, both positive and negative.
- Stimulus driven behaviour

29
Q

deficits in the medio-temporal lobe

A

(includes hippocampus):

- Difficulties understanding location in space 
- Difficulties judging and navigating distances 
- Difficulties in using environmental context to navigate 
- Difficulties with long term declarative memory.
30
Q

agnosia

A

a rare disorder characterised by an inability to recognise and identify objects or persons.
Difficulty recognising the geometric features of an object or face.
Can be limited to one sensory modality such as vision or hearing.
Typically results from damage to the occipital or parietal lobes.

31
Q

anterograde amnesia

A

impaired ability to learn new information following an onset of amnesia.

32
Q

retrograde amnesia

A

impaired ability to recall past events and previously familiar information.
Intact procedural memory.

33
Q

amnesia

A

Caused by damage to the hippocampus.

Amnesia is not the same as dementia, dementia can often have amnesia problems but also a variety of cognitive issues.
