YR12 - Chapter 4, Learning Flashcards
Learning
the process of acquiring knowledge, skills, or behaviours through experience
Behaviourist approaches to learning
theories that propose learning occurs by interacting with the external environment
Classical conditioning
a process of learning through the involuntary association between a NS and an UCS that results in a CR
Before conditioning
the first stage of classical conditioning, during which the NS has no associations and therefore does not produce any significant response
Neutral stimulus
the stimulus that produces no significant response prior to conditioning
Unconditioned stimulus
the stimulus that produces an unconscious response
Unconditioned response
a naturally occurring behaviour in response to a stimulus
During conditioning
the second stage of classical conditioning, during which the NS is repeatedly paired with the UCS , producing the UCR
Timing in during conditioning
The NS must be presented first, remaining until the UCS is presented within half a second. The UCS should not be presented any later than this.
After conditioning
the third stage of classical conditioning, during which the NS becomes the CS , producing a CR
Conditioned stimulus
the stimulus (originally the NS ) that produces a CR after being repeatedly paired with an UCS
Conditioned response
the response that occurs involuntarily after the CS is presented
Explain Pavlov’s experiment
Before:
- sound of bell (NS) produces no response
- dog food (UCS) triggers salivation
During:
- sound of bell (NS) is repeatedly paired with giving dog food (UCS) to trigger salivation (UCR)
After:
- bell (NS) has become the CS which triggers salivation (CR)
Operant conditioning
a three-phase learning process that involves an antecedent, behaviour, and consequence, whereby the consequence of a behaviour determines the likelihood that it
will reoccur
1st phase - antecedent
the stimulus or event that precedes and often elicits a particular behaviour
example - owner commanding dog to ‘sit’
2nd phase - behaviour
The voluntary actions that occur in the presence of the antecedent
example - dog sits in response to the command word ‘sit’
3rd phase - Consequence
The outcome of the behaviour, which determines the likelihood that it will occur again
example - owner gives dog a treat after they sit, increased likelihood of dog repeating behaviour
Types of consequences:
Reinforcement
a consequence that increases the likelihood of a behaviour occurring.
positive reinforcement
the addition of a desirable stimulus, which in turn increases the likelihood of a behaviour reoccurring
example - studying hard for a test and receiving high marks
negative reinforcement
the removal of an undesirable stimulus, which in turn increases the likelihood of a behaviour reoccurring
example - going for a run when you’re stresses, which alleviates stress feelings
