Q

what are the three assumptions of the infomation processing approach?

A
  • info is processed by a series of systems
  • systems transform or alter the info
  • the aim of research is to specify the processes and structures that underline cognative performance

32
Q

what is episodic memory?

A

the memory of your own set of autobiographical events

33
Q

what is semantic memory?

A

factual knowledge posessed about the outside world

34
Q

what are the three r’s?

A

recall, recognition and relearning

35
Q

what is recall?

A

being able to access the information without being cued

36
Q

what is recognition?

A

identifying after experiencing it again

37
Q

what is relearning?

A

involves retaining info that has been previously learned

38
Q

what is the definition of forgetting?

A

a failure to access info that had previously been stored in memory

39
Q

what is forgetting caused by?

A

a range of different deficiencies in encoding, storage and retrieval

40
Q

what are the causes of forgetting?

A

retrieval failure theory, interference theory, motivated forgetting, decay and organic

41
Q

what is the retrieval forgetting theory?

A

forgetting occurs because of a failure to use the right, correct or appropriate cues at a certain time

42
Q

what is interference theory?

A

when two pieces of info are so similar it leads to a situation called interference causing us to forget the info

43
Q

what are the two types of interference?

A

proactive interference and retroactive interference

44
Q

what is proactive interference?

A

interference of old memories on the retrieval of new info

45
Q

what is retroactive interference?

A

new info interfers with the ability to remember old info

46
Q

what is motivated forgetting?

A

when there is a strong desire to forget because the memory is either too traumatic, disturbing, anxiety provoking or upsetting

47
Q

what are the two types of motivated forgetting?

A

repression and suppression

48
Q

what is repression?

A

keeping thought buried in the unconscious

49
Q

what is supression

A

a deliberate effort to keep them out of the conscious mind

50
Q

what is decay theory?

A

forgetting occurs because the memory trace tends to gradually fade or decay over time

51
Q

what is the organic theory of forgetting?

A

forgetting occurs due to some brain damage

52
Q

what is learning?

A

a relatively permanent change often of behaviour, that occurs as a result of experience

53
Q

what is classical conditioning?

A

an association forming between two stimuli, one of which is not normally associated with the response, such that the appearance of stimulus alone results in the response behaviour

54
Q

what is conditioning?

A

the association made by the learner between a stimulus and a response

55
Q

what is stimulus?

A

any variable present that may trigger a response

56
Q

what is a response?

A

any action or behaviour that is exhibited

57
Q

what is the neutral stimulus?

A

any stimulus that produces no relevant responses prior to classical conditioning

58
Q

what is the unconditioned stimulus?

A

any stimulus that consistently leads to a reflexive response

59
Q

what is the conditioned stimulus?

A

a previously neutral response that has become associated with a stimulus by which it was not previously caused by the process

60
Q

what is the unconditioned response?

A

unlearned, reflexive and involuntary response to a stimulus

61
Q

what is the conditioned response?

A

a reflexive and involuntary response that has become associated with a stimulus by which it was not previously caused during classical conditioning

62
Q

what is operant conditioning?

A

the changing of behaviour by the use of reinforcement which is given after the desired response

63
Q

what are the three types of responses or operants?

A

neutral operants
reinforcers
punishers

64
Q

what is positive reinforcement?

A

strengthens a behaviour by providing a rewarding consequence

65
Q

what is negative reinforcement?

A

the removal of an unpleasant reinforcer to strengthen behaviour

66
Q

what is punishment?

A

designed to weaken or eliminate a response

67
Q

what are schedules of reinforcement?

A

different patterns had different effects on the speed of learning

68
Q

what are the different types of reinforcement?

A
continuous 
fixed ratio 
variable ratio
fixed interval
variable internal
69
Q

what is behaviour shaping?

A

principles of operant conditioning can be used to produce extremely complex behaviour

70
Q

what is observational learning?

A

the environment causes behaviour and learning, and behaviour can change the environment

71
Q

what are the factors involved in observational learning?

A

attention
retention
reproduction
innovation

72
Q

what is behaviour modification?

A

application of classical and operant techniques

73
Q

what are the techniques of modifying behaviour?

A

token economy
systematic desensitisation
cbt
positive or negative reinforcement

74
Q

what are token economies?

A

artificial systems of reward and reinforcement where symbolic markers are used to reward behaviour

75
Q

what is systematic desensitisation?

A

the fear response is replaced with a more relaxed response in a step by step process

76
Q

what is cbt?

A

a type of psychotherapy that helps people to change unhelpful or unhealthy thinking, habits, feelings and behaviours
