Sac 2 - Learning and shit

1. Neural plasticity

   • The changes in connections between neurons, as the fundamental mechanisms of learning. 
   • Learning
     • A relatively permanent change in behavior due to experience. 
   • Memory
     • Processing, storing and retrieval of information acquired through learning.
   • Long term potentiation
     • Long-term potentiation refers to the long lasting strengthening of a connecting neurons 
   • Long term depression
     • the long lasting decrease in a strength of a neurons synaptic transmission. 
   • synaptic plasticity

2. Chemicals

   • Neurotransmitters
     • Glutamate
     • Adrenalin
   • Excitatory neurons
   • Inhibitory neurons

3. Classical conditioning

   • 3 phase model
     • Acquisition
       • is the overall process of learning to associate 2 stimulus' 
     • Extinction
       • the removal of the association of the 2 stimulus' 
     • Spontaneous recovery
       • is the reappearance of the conditioned response when the conditioned stimulus is presented even after extinction. 
   • stimulus generalisation
     • In operant conditioning, stimulus generalisation occurs when the correct response is made to another stimulus that is similar (but not necessarily identical) to the stimulus that was present.
   • Stimulus discrimination
     • In operant conditioning, stimulus discrimination occurs when an organism makes the correct response to a stimulus and is reinforced, but does not respond to any other stimulus, even when stimuli are similar (but not identical).

4. Little Albert experiment

   • Conditioned emotional response
   • Voluntary participation
   • Informed consent
