Learning Flashcards
What is learning in terms of animal learning research?
It is a long term change in behaviour brought about by experience
What are the four types of innate behavioural patterns?
Reflexes, tropisms, fixed action patterns and reaction chains
What are tropisms?
Tropisms are movement or change in orientation of an animal or a plant
What are fixed action patterns?
They are a sequence of behaviours that occur in rigid order
What are reaction chains?
Reaction chains are sequences of behaviours that occur in rigid order
What is non-associative learning?
Non-associative learning is learning where animals do not learn to associate one thing with another
What is habituation?
Habituation is the decrease in response strength over presentations of low to moderate intensity stimulus
What is dishabituation?
Dishabituation is when you habituate an animal to one stimulus. After it stops responding, present new stimulus. Then present old stimulus again. The response to the original stimulus will recover but not return to full strength
What is sensitization?
Sensitization is if a stimuli are moderate to high in intensity animals become sensitized
When does acquisition occur?
Acquisition occurs during initial CS-US pairing
What happens in acquisition?
There’s a nonmonotonic increase in CR strength that reaches an asymptote
What is an asymptote?
AN asymptote is the height at which a line levels off
What does a stronger US lead to in terms of the asymptote?
A stronger US leads to a higher asymptote in CR strength and the asymptote is reached quicker
What does a stronger CS relate to in terms if the asymptote?
A stronger CS is related to reaching the asymptote more quickly but not to the level of the asymptote
How does extinction occur?
Extinction is reducing the strength of the CR by repeatedly presenting the CS without the US
