25
Reinforcement
Reinforcement a type of consequence that makes the behaviour more likely to occur again
26

Positive reinforcement when a stimulus is added in order to encourage a behaviour to occur again
27
Negative reinforcement
Negative reinforcement when a stimulus is removed in order to encourage a behaviour to occur again
28
Punishment
Punishment a type of consequence that makes the behaviour less likely to occur again
29
Positive punishment
Positive punishment when a stimulus is added in order to discourage a behaviour from occurring again
30
Response cost
Response cost (also known as negative punishment) when a stimulus is removed in order to discourage a behaviour occurring again
31
Extinction
Extinction when the conditioned behaviour no longer occurs in response to an antecedent, for an extended period of time
32
Spontaneous recovery
Spontaneous recovery when the behaviour occurs in response to the antecedent again, following a period of extinction
33
Stimulus discrimination
Stimulus discrimination when the behaviour occurs in response to a specific antecedent only
34
Stimulus generalisition
Stimulus generalisation when the behaviour occurs in response to a similar, but different, antecedent
35
Observational learning
Observational learning (also known as social learning, vicarious conditioning, or modelling) a type of learning that occurs through watching the actions of a model and the consequences that their actions receive
36
Model
Model the individual who is performing the behaviour that is being watched/observed
37
Attention
Attention the first stage of observational learning. Learners must actively focus on the model in order to learn
38
Retention
Retention the second stage of observational learning. The learner must create a mental representation and remember (retain) the behaviour the model has demonstrated
39
Reproduction
Reproduction the third stage of observational learning. The learner must have the physical and mental capabilities to reproduce the observed behaviour
40
Motivation
Motivation the fourth stage | of observational learning. The learner must want to reproduce the behaviour in order for learning to occur
41
Reinforcement
Reinforcement the fifth stage of observational learning. If the learner receives a desirable consequence for their behaviour, they are more likely to reproduce the behaviour again in the future
42
Memory
Memory the process of encoding, storing and retrieving learned information
43
Atkinson-shiffrin multi-store model of learning
Atkinson-Shiffrin multi-store model of memory a model of memory which outlines the flow of information in memory formation and retrieval through three separate stores of memory; sensory, short-term and long-term, each of which have a different function, capacity and duration
44
Encoding
Encoding the process of converting raw information from stimuli into a useable form which can be stored in the brain
45
Storage
Storage retaining converted information so it can be accessed and used in the future
46
Retrieval
Retrieval accessing information which has previously been stored in the brain
47

48
Echoic memory
Echoic memory a type of sensory memory which temporarily stores auditory information
49

50

Short-term memory (STM) | store of memory which holds information that is consciously being attended to and actively manipulated
51
Long term memory
Long-term memory (LTM) store of memory in which a potentially unlimited amount of information is stored for a relatively permanent amount of time
52

Amyloid plaques
Amyloid plaques fragments of the protein beta-amyloid that accumulate into insoluble plaques that inhibit communication between neurons
68
Neurofibrillary tangles
Neurofibrillary tangles an accumulation of the protein tau that forms insoluble tangles within neurons, which then inhibit the transport of essential substances throughout the neuron, eventually killing the neuron entirely
