Learning Flashcards
What does learning refer to?
Any enduring change in the way an organism responds based on its experience
What is habituation?
The decreasing strength of a reflex response after repeated presentations of the stimulus
What is classical conditioning also known as?
Pavlovian conditioning
What is classical conditioning?
A stimulus acquires a capacity to produce a response that was previously produced by a different stimulus
In classical conditioning, what is an unconditioned stimulus?
A stimulus that naturally elicits a response
In classical conditioning, what is an conditioned stimulus?
A stimulus that, through learning, comes to elicit a response
In classical conditioning, what is a conditioned response?
A response that has been learned
In the dog salivation example of classical conditioning, what is
a) the neutral stimulus
b) the unconditioned stimulus
c) the unconditioned response
d) the conditioned stimulus
e) the conditioned response?
a) bell ringing
b) meat
c) salivation
d) bell ringing
e) salivation
What is the inter-stimulus interval?
The time between the presentation of the conditioned stimulus and the unconditioned stimulus and the order of presentation
What are the four types of classical conditioning?
- Simultaneous conditioning (CS and UCS begin and end together)
- Short-delayed conditioning (CS begins just before UCS, end together)
- Trace (forward) conditioning (CS begins and ends before UCS is presented)
- Backward conditioning (UCS begins and ends before CS is presented)
When does stimulus generalisation occur?
When an organism learns to respond to stimuli that resemble the CS with a similar response
When does stimulus discrimination occur?
When an organism learns to respond to a restricted range of stimuli (e.g. Pavlov’s dogs could discriminate between bell sounds)
In classical conditioning, when does extinction occur?
When a CR is weakened by presentation of the CS without the UCS; a learned inhibition of responding
What is spontaneous recovery?
The short-lived re-emergence of a previously extinguished CR
What does extinction have important implications for?
Treatment of phobias
What are four areas of everyday life in which conditioning is evident?
Fears, emotional responses, physiological responses and drug effects
What is higher-order conditioning?
When a new CS is developed from an existing CS/CR (e.g. red light + bell ringing = salivation)
How does individual learning history affect conditioning?
- Prior history with stimuli
- Biological preparedness
- Blocking & latent inhibition
What is blocking?
The failure of a stimulus to elicit a CR when it is combined with another stimulus that already elicits the response
What is latent inhibition?
The initial exposure to a neutral stimulus without a UCS slows the process of later learning the CS-UCS association and developing a CR (e.g. bell repeatedly ringing without presentation of meat)
What is prepared learning?
The evolved tendency of some associations to be learned more readily than others
What are operant behaviours?
Behaviours that are influenced by their consequences
What does the law of effect state?
Behaviour is controlled by its consequences
What is operant conditioning?
Learning to operate on the environment to produce a consequence
What are the two types of environmental consequences that produce operant conditioning?
Reinforcement and punishment
