25
Reinforcer
a consequence that increase the likelihood of the behaviour being repeated
26
Positive Reinforcer
something good is added to increase behaviour
27
Negative Reinforcer
avoidance or removal or something unpleasant to increase behaviour
28
Punishment
consequence that weakens or reduces the likelihood of a response repeating
29
Positive Punishment
something unpleasant is added
30
Negative Punishment
something good is lost
31
Reinforcement is better than punishment because… (2)
punishing can become more of a reward due to attention received and can become abuse
32
Stimulus generalisation (OC)
when the same response is made to a similar antecedent that was
33
Stimulus discrimination (OC)
only makes the response to the original antecedent, nothing else
34
Extinction (OC)
gradual decrease in the strength of a conditioned response following a lack of consequences. A learned response that is no longer punished or reinforced will stop.
35
Spontaneous Recovery (OC)
occurs after extinction, when the conditioned behaviour shows in the absence of the antecedent that produced behaviour
36
Observation learning
a person learns by watching a behaviour demonstrated by another
37
Modelling
an observer demonstrated behaviour observed
38
Attention
cognitive aspect, individuals need to pay attention in order to observe the modelled behaviour
39
Retention
behaviour must be stored in memory as a mental representation to be retrieved and copied
40
Reproduction
learner must have physical and intellectual ability to convert mental representations into actions
41
Motivation
learner must want to imitate the behaviour
42
Bandura’s Bobo Doll experiment concludes that...
people learn from not only being rewarded or punished but watching an individual being rewarded or punished
43
‘Little Albert’ experiment (CC)
``` UCS – loud noise UCR – fear/crying NS – white rate CS – white rat CR – fear/crying ```
44
‘Little Albert’ experiment (ethical issues) (4)
- did not get consent from albert mother - today, using experiments to evoke fear would not be allowed - emotionally traumatising - did not extinguish the conditioned response
45
Memory
the way in which the mind remembers and stores information
46
Sensory Memory Function (2)
- received sensory information from environment | - paying attention transfers information into STM
47
Sensory Memory Capacity
potentially unlimited
48
Sensory Memory Duration
- about 0.2 to 4 seconds
49
Short-term Memory | (STM) Function
maintains information in conscious awareness from immediate use
50
Short-term Memory | STM) Capacity (2
- 7 + or – 2 pieces of information | - can increase through chunking
51
Short-term Memory | (STM) Duration
- from 18 to 10 seconds | - longer if maintenance rehearsal is used
52
Long-term Memory (LTM) | Function
information storage for re-access and use at a later time
53
Long-term Memory (LTM) Capacity
potentially unlimited
54
Long-term Memory (LTM) Duration (2)
- potentially permanent | - some information can be lost or inaccessible over time
55
what is iconic memory
visual memory
56
Iconic memory duration
about 250 milliseconds
57
what is echoic memory
auditory memory
58
Echoic memory duration
about 3 to 4 seconds
59
What is procedural memory
how to do something
60
What is declarative memory
what something is
61
Two types of declarative memory
- episodic (autobiographical) | - semantic (information)
62
What is explicit memory
information you have to constantly work to remember
63
What is implicit memory
information you have unconsciously and effortlessly
64
Recall
retrieving information from LTM into STM (consciousness)
65
Free recall
retrieving information in any order
66
Serial recall
reproducing information in the order in which it was retrieved
67
Queued recall
used prompts or cues to aid retrieval
68
Recognition
identifying information as having been previously stored, matching information with that stored in LTM
69
Relearning
previously learned information is relearned more quickly, suggest some information has been retained in LTM
70
Reconstruction
combining stored information with other available information – tendency to complete gaps in memory (most common with episodic memories)
71
Alzheimer’s symptoms
forgetfulness, difficulty with time, language problems and inability to recognise people
72
Alzheimer’s causes
- beta – amyloid clusters stick together to form plaque | - protein strands or threads become in tangled forming neurofibrillary tangles
73
Amnesia
loss of memory, maybe partial or total, temporary, or permanent
74
Anterograde amnesia
inability to form or store new long-term memories
75
Retrieval Cue
any stimulus that assists in the retrieval of information stored in memory
76
Context-Dependent Cues
environmental cues present when a memory was formed
77
State-Dependent Cues
cues associated with physiological or psychological state when the memory was formed
78
Rehearsal (encoding)
act of getting information into our long-term memory through processing
79
The serial Position Effect is the....
tendency to recall more items from the beginning and end of a list
80
Maintenance Rehearsal is _____ which ______ however _____
repetition, keeps info in STM for longer than 18–2 seconds, rarely enough to transfer information into long-term memory
81
Elaborative Rehearsal links _____
new information in a meaningful way with information already stored in long-term memory
82
Eyewitness testimony
is any firsthand account given by individuals of an event they have seen
83
Leading question
is asked in such a way as to suggest what answer is desired
84
Fallibility of Memory concludes that ____
eyewitness testimony is not always accurate because eyewitness reconstruct their memories and their reconstructed memories can be manipulated by leading questions that contain misleading information
