Q

What has dopamine been linked to?

A

Hallucinations and delusions

17
Q

What can too much dopamine lead to?

A

Schizophrenia

18
Q

How do anti-psychotics work?

A

Reducing dopamine levels

19
Q

What is assumption two of the biological approach?

A

Behaviour can be explained by localisation of brain function

20
Q

What does ‘localisation of function’ suggest?

A

Certain areas of the brain are responsible for particular functions

21
Q

What are the four lobes of the brain and what is their function?

A

Frontal Lobe - thinking, language (Broca’s area) and motor skills
Parietal Lobe - Sensory information
Occipital Lobe - Visual information and processing
Temporal Lobe - Auditory information (Wernicke’s area) and memory

22
Q

What may happen if each lobe is damaged?

A

Frontal Lobe - loss of fine motor skills and Broca’s aphasia (trouble producing speech)
Temporal Lobe - changes in emotional state and Wernicke’s aphasia (trouble understanding speech)
Occipital Lobe - perception issues
Parietal Lobe - sensory issues

23
Q

What is the well-known example of localisation of function?

A

Phineas Gage

24
Q

What happened to Gage?

A

Had an accident involving a metal rod going through his frontal lobe and experienced drastic personality change e.g. rude ways and more aggressive

25
Q

What is assumption three of the biological approach?

A

Behaviour can be explained by evolutionary experiences

26
Q

What does ‘evolve’ mean?

A

Change through time

27
Q

What is natural selection?

A

The idea that any genetically determined behaviour which increases chances of survival, will be naturally selected and passed down generations

28
Q

What is an example of evolutionary experiences?

A

Nyctophobia - fear of the dark once needed to be aware of predators in cavemen years

29
Q

What did Charles Darwin publish in 1879?

A

The Origins of Species - all living things must have evolved through time to become better suited to their environment

30
Q

What is ‘environment of evolutionary adaptiveness’?

A

Explains why humans have adapted from forests to developing savannahs in Africa such as large brains and ability to form relationships.
