Plasticity
Is the ability of the brain's neural structure or function to be changed by experience throughout the lifespan.
1 of 13
Which areas of the brain have a higher level of plasticity?
Sensory and motor cortices
2 of 13
Before conditioning
CS (bell) leads to no salivation or irrelevant response. Then, UCS (food) leads to salivation (UCR) bell = neutral stimulus
3 of 13
During conditioing
CS..bell is associated with UCS which leads to salivation
4 of 13
After conditioning
CS of bell leads to CR of salivation
5 of 13
Dendrites
During learning, they receive neurotransmitters across the synaptic gap
6 of 13
Sprouting
Is the growth of new bushier nerve fibres with more branches to make new connections.
7 of 13
Rerouting
An undamaged neuron that has lost a connection with an active neuron may seek a new active neuron and connect with it instead.
8 of 13
Adaptive plasticity
Refers to changes occurring in the brain's neural structure to enable adjustment to experience, to compensate for lost function and/or to maximise remaining functions in the event of brain damge.

Synaptogenesis
Process of forming new synapses
10 of 13
Synaptic pruning
Process of eliminating synaptic connections
11 of 13
Continuous reinforcement
Reinforcing every correct response after it occurs. Learning is usually most rapid if the correct response is reinforced every time it occurs initially.
12 of 13
Token economy
Is a setting in which an individual receives tokens (reinforcers) for desired behaviour. These tokens can then be collected and exchanged for other reinforcers in the form of actual, or 'real,' rewards.
