Name all types of non-declarative (implicit, procedual) learning
Procedural (Skills, habits)
Priming (perceptual, learning)
Non-associative ( habituation, sensitization)
Associative ( classical conditioning)
What is Priming?change in individual
Change in inividual's response to the repeated stimulus
What is perceptual learning?
Change how you perceive the stimulus
Name characteristics of perceptual learning
capacity to detect subtle differences through repeated exposure to stimuli
→ Happens through mere exposure to stimuli, no conscious effort!
→ Different from priming: it is long lasting
Describe the sensorical information pathway to the LTM
Perceptual Learning: Neural Basis:
What is the key feature of perceptual Learning?
What will happen when you undergo a hearing prcedure with a prolonged period of one frequence?
Cortcal plasticity
Respective field changes —> brain area expans
Simultaniously —> unused brain area weakens, due to competition of brain area
How long doa
Eskt take for morphological changes to appear after training?
Round about 2h
If not actively recalled, loss after 1d
How does stimulussharpening arise, soley from synaptic input (I.e. the cochlea)?
Name an example for associative learning and describe it
An example would be the Pawlowtian dog
Uncoditioned stimulus elicits uncoditioned response
Pairing uncoditioned stimulus with neutral stimulus
Neutral stimulus become conditioned stimulus
Conditioned stimulus without uncoditioned one now elicits conditioned stimulus
Association complete
Describe the properties of classical conditioning
What is the induction protocol?
How long is the optimal Cs-US interval?
It describes the time onset of the US relative to the CS
The optimal time interval is about 200ms long
What is the associative bias?
→ Some stimuli are more naturally associated
(e.g., food nausea, etc.).
Taxi → Cinema → Dinner → Sickness
Explain the CS-US vs the CS-R assiciation. Which two models are named? Whats the difference in in which groups are they normally found?
What has learning to do with the prediction error?
Which model is associated with this?
Prediction Error → learning occurrs when there is a mismatch between the
subject‘s expectancy of US, and the actual outcome.
Learning → process which tends to reduce the prediction error!
We do not learn anymore when the prediction error is zero!
The Rescorla-Wagner-Model
Explain Blocking in respect to the Roscorla- Wagner- Model
How do Fear conditioning and Classical conditioning differ in terms of localization?
The fear conditioning is anatomocally localized in the basolateral Amygdala,
while the Pavlovian conditioning can be found in the Stfiatum, more precisely in the NAc (Nucleus Accumbens)
