U3AOS2A - Learning Flashcards
NOTE - When answering questions, ensure to highlight and read the question properly
Define learning
- Relatively permanent change in behaviour that occurs as a result of experience
- Can be intentional or unintentional (active or passive)
How is it known that learning has taken place?
- Can be inferred due to modifications in the response of the organism to stimuli provided in the environment
Define behaviourist approaches
- An approach to learning that states that behaviours are learned through interactions with the environment
Define conditioning
- The learning process by which the behaviour of an organism becomes dependent on an event/stimulus occurring in its environment
Define stimulus
- Any object or event that elicits a response from an organism
Define response
- A reaction by an organism to a stimulus
Define classical conditioning
- Occurs through the repeated association of 2 or more different stimuli
- Learning is said to have occurred when a particular stimulus consistently produces a response that it did not previously produce
- Involuntary linking of neutral stimulus and unconditioned stimulus over a number of trials
Explain the 5 components of classical conditioning
- Unconditioned Stimulus (UCS) - Any stimulus that consistently produces a particular, naturally occurring, automatic response
-
Unconditioned Response (UCR) - Response that occurs automatically when the UCS is presented
- Reflexive involuntary response predictably caused by a UCS
- Neutral Stimulus (NS) - Any stimulus that does not normally produce a predictable response
- Conditioned Stimulus (CS) - Stimulus that is ‘neutral’ at the start of the conditioning process but eventually elicits a similar response to what is caused by the UCS
-
Conditioned Response (CR) - Learned response produced by the CS
- Similar to UCR but is triggered by the CS alone
Note : When answering a question, things like ‘Unconditioned Stimulus’ must be written in full at least once because abbreviating
Explain the 3 phases of classical conditioning
-
Before
- UCS and NS are seperate
- No learning has taken place yet
-
During
- UCS and NS are repeatedly paired together through acquisition
- Presented simultaneously OR NS is followed closely by UCS
-
After
- NS becomes CS and produces a CR without the presence of a UCS
- Conditioned (learned) response is not necessarily the same as the unconditioned response
Explain acquisition in relation to classical conditioning
- The overall process of pairing the unconditioned stimulus and the conditioned (neutral) stimulus
- Each pairing is referred to as a ‘trial’
- Stimuli occur in close succession and always in the same sequence
- Duration can vary
- Rate of learning is very fast early on into the acquisition process
NOTE : Questions about acquisition require a statement about the presentation of when the NS and UCS are presented (close succession)
What is extinction?
- When the CS is presented alone, CR declines irregularly until it is extinguished and no longer occurs
Name and explain the 3 factors that influence classical conditioning
-
Nature of Response
- UCR must be automatic and involuntary (reflex)
- Anticipatory Behaviour - Learning to expect an event, may not occur without any thought like Pavlov proposed
-
Association of Stimuli
- If an individual does not associate the 2 stimuli, conditioning will not occur
- Contiguity - Associating events that occur close together in time and/or space
-
Timing of NS and UCS pairing
- NS should be presented before the UCS
- Should occur not more than half a second before the UCS
- According to Pavlov, longer time intervals were less effective
Define operant conditioning
- Also known as instrumental conditioning
- A learning process where the consequences of the behaviour determine the likelihood that it will be performed again in the future
- Learner is voluntarily aware of the behaviour they are exhibiting in response to stimuli
What is an operant?
- An operant is a voluntary response that acts on the environment to produce some kind of consequence
- ‘Operating to produce an effect’
- First appear spontaneously and can be controlled by the organism but are greatly influenced by their consequences
Why is operant conditioning a form of associative learning?
- Because stimuli is associated with responses (consequences)
What is an antecedent in relation to classical conditioning?
- An antecedent is something that precedes behaviour
- Within classical conditioning an antecedent that elicits a specific response is paired with an antecedent that does not elicit the response
Define antecedent
- An environmental stimulus that has become associated with the consequence of a voluntary behaviour
- It NEEDS to be from the ENVIRONMENT and directly precede the behaviour
- Presents a choice
Explain the 3 phases of operant conditioning
-
Antecedent - What happened before
- Anything in the organism’s environment
- Already in place before any behaviour occurs
- Can signal that behaving in a certain way is likely to produce a specific consequence
- Cues that tell us what to do
- When it influences behaviour it is called an antecedent stimulus/condition or discriminative stimulus
-
Behaviour - What happens
- Voluntary action that occurs in the presence of the antecedent stimulus
- Can be one specific action or a pattern of actions
- Has an effect on the environment
-
Consequence - What happens after
- Environmental event that occurs immediately after the behaviour
- Has effect on the occurrence of the behaviour
ABC’s
Define reinforcement and punishment
-
Reinforcement - Process in which a stimulus strengthens or increases the frequency/ likelihood of a response it follows
- Positive - ADDING a desirable stimulus
- Negative - REMOVING an undesirable stimulus
-
Punishment - Process in which a stimulus weakens or decreases the frequency/ likelihood of a response it follows
- Positive - ADDING an undesirable stimulus
- Negative - REMOVING a desirable stimulus (response cost)
What affects the effectiveness of a consequence?
-
Appropriateness
- Recipient must interpret it in the desired way or it will not be effective
-
Timing
- Consequence needs to be given immediately after the response
- If there is a delay, learning will either be slow or not occur at all
-
Order
- Consequence needs to be given after a response
