44
Q

Do schema’s affect our behaviour?

A

YES - as we get older our schema’s become more sophisticated and detailed

45
Q

A

Process info quickly (mental shortcuts) in our environment

46
Q

What can schema’s distort?

A

Our interpretations (stereotypes)

47
Q

What are the 2 models the cognitive approach put forward?

A

Theoretical models - explains mental processes, makes intelligent guesses, information processing model
Computer models - brain processes like a computer, central processing unit is the brain, it codes and stores

48
Q

What does the information processing model in the theoretical model in SLT tell us?

A

We input something from the environment through senses
We process it, encode it using schema’s
We output it, observable behavior

49
Q

54
Q

What are the 3 main assumptions of the biological approach?

Must look at structures of genes, neurochemistry and the nervous system
The mind lives in the brain (mental processes of the mind are separate from genes)

55
Q

What are the 4 components that make up the biological approach?

A

Genetic basis of behaviour
Genotype and phenotype
Evolution and behaviour
Influence of neurochemistry on behaviour

56
Q

What do bio-psychologists believe about genes and behaviour?

A

Genes influence your behaviour (23 chromosomes we are born with are our genotype and form basis of behaviour)

57
Q

What does the biological approach believe about our gene characteristics and our interaction with the environment?

A

They depend partly on each other but still firmly on the NATURE side of the debate

58
Q

What is a way to look at the genetic basis of behaviour?

A

Twin studies -
Identical twin (monozygotic) shares 100% genes
Non-identical twin (dizygotic) shares 50% genes (same as siblings)

59
Q

What is the genotype?

A

The actual genetic makeup that occurs at conception (dictates characteristics such as eye and hair colour)

60
Q

What is the phenotype?

A

The product of what happens when the genotype interacts with the environment (adult identical twins looking different because of dyed hair)

61
Q

How does genotype and phenotype link to the biological approach?

A

Behaviour depends on the interaction between them

62
Q

What would biological psychologists argue about behavior and evolution?

A

Certain human characteristics exist because they have evolved - e.g aggression may be more attractive to the other sex so this helps with mate selection and its passed down

63
Q

What is neurochemistry?

A

The biochemistry of the central nervous system

64
Q

What are chemicals in the brain called?

A

Neurotransmitters (thought to affect behavior) such as dopamine related to schizophrenia

65
Q

What are the 2 strengths of the biological approach?

A

Range of precise scientific methods (lab experiments, twin studies) so increases reliability
Real world applications - psychoactive drugs to treat mental illnesses

66
Q

What are the 2 weaknesses of the biological approach?

A

Reductionist - dehumanizing as presents us as biological machines
Determinist - says its governed by genetics over which we have no control, can we be accountable for our actions then????

67
Q

What do biopsychlogists believe about activity in the nervous system?

A

It cases all behaviour and experiences

68
Q

What is the nervous system?

Sympathetic and parasympathetic nervous system

81
Q

What does the sympathetic nervous system do?

A
