L08: Learning And Memory Flashcards
Why is it important to understand how people behaviour
As doctors if we know why people behave the way they do we may be able to change it and promote healthy behaviours
What is classical conditioning about
Conditioning with a stimulus
Describe the stages of classical conditioning
Unconditioned stimulus
Neutral stimulus
Conditioning procedure
Neural stimulus becomes conditioned stimulus
What is an unconditioned stimulus, give an example from Pavlov dog
Food
What is the neutral stimulus about
If you ring a bell in the absence of the food the dog will not salivate
What is the conditioning procedure
Ringing a bell with food makes the dog salivate
What happens with the neutral stimulus
becomes the conditioned stimulus so in the absence of food the dog salivates
Therefore at the end of the procedure what does the conditioned stimulus allow
A conditioned response
Give real life examples of how classical conditioning is widespread
Fear
Pain
How does the little Albert study represent classical conditioning
1) An infant was not scared of rats
2) An infant was scared of loud noise
3) Loud noice and rat was combined which caused fear
4) Rat alone caused fear after conditioning
What is generalisation
When the stimulus becomes generalised to other stimuli that are similiar to the stimulus
What is operant (instrumental) conditioning
When consequences lead to changes in behaviour
What is social (observational) learning
When you learn by observing other people i.e social learning
Name an example of social learning
Boob-doll experiment
What is the boob-doll experiment about
1) children watched adults beat up a bobo doll
2) children was then taken to a room and made upset
3) Children started beating up the bobo doll as the way the adults did
What does the bobo-doll experiment show
A link between media violence and family history leads to violent child
How is memory linked to learning
To learn we need to remember
To remember you can only remember what you have learnt
What are the 3 stages of memory
1) encoding
2) storage
3) retrieval
What is the encoding stage
Process of transferring info from one memory stage to the next e.g from sensory memory to short memory then to long term memory
What is storage stage
Maintaining info
When is the storage stage not temporary
In long term memory
What is the retrieval stage
Process of bringing info from long term memory to conscious level in short term memory
How does the information flow into memory
1) external stimulus
2) sensory memory
3) short term memory
4) long term memory - ready to be retrieved
What is sensory memory related to
Perception
Does short term memory have a capacity
Yes
To maintain short term memory what has to be done
Rehearsal
What is the primary and recency effect known as
Easier to remember first and last item
How do we test for short term memory
Memory span task
What is the memory span task
Present random letter at one at a time and remember it in the same order
On average how many letters should someone remember
7 letters
Does long term memory have a capacity
No it has an unlimited capacity
How can long term memory be forgotten
Interference
Decay
What does interference mean
Forgetting due to other information interfering
What does decay mean
Info that is not retrieved is at risk of being forgotten so you either use it or lose it
What are the 2 types of long term memory
Declarative memory
Procedural memory
What is procedural memory
Knowing how to do things
What is declarative memory
Remembering facts, data and events
What can declarative memory be split into
Episodic memory
Semantic memory
What is episodic memory
Personal experience in life
What is semantic memory
Factual knowledge memory
After consultation on average how much info do patients remember
50%
What causes the decrease in remember info
Anxiety
Elderly
Give exmaple of when memory can be impaired
Dementia
Amnesia
Delirium
Depression
What is amnesia
A focal brain lesion
What are the types of amnesia
Anterograde amnesia
Retrograde amnesia
What is anterograde Amnesia
Cannot remember events after brain damage
What is retrograde amnesia
Cannot remember events before brain damage
Which lobe of the brain has a role in memory
Temporal lobe (medial region)
What are the symptoms of anterograde amnesia
Difficulty learning new info Confusion Personality and intelligence unaffected Good memory of the past Trouble holding a job
What are the 2 components of operant conditioning
Reinforcement
Punishment
What is the aim of reinforcement
Increase/maintain behaviour
What is the aim of punishment
Decrease behaviour
What can reinforcement or punishment be
Positive
Negative
What does positive mean
Adding stimulus that is good or bad depending of it its for reinforcement or punishment
What stimulus (positive) do we add for reinforcement
Pleasant stimulus
What stimulus (positive) do we add for punishment
Unpleasant stimulus
What does negative mean
Removing stimulus that is good or bad
What stimulus to we remove for reinforcement
Unpleasant stimulus
What stimulus do we remove for punishment
Pleasant stimulus
