Q

How does a neutral stimulus become a conditioned stimulus?

A

By presenting a presenting a neutral stimulus prior to unconditioned stimulus over time the organism will respond to the neutral stimulus thus becoming the conditioned stimulus

I.e ring bell (neutral stimulus) before food (unconditioned stimulus) eventually ringing bell will induce salivating (conditioned response)

25
What is ratio reinforcement?
Based on performance of behaviour rather than time
26
What is a fixed ratio example?
Getting a free coffee after every 6
27
What is a variable ratio example?
Gambling. Relies on number of performances of good behaviour but is not a constant number. You don’t get s reward every time you gamble but you have to gamble In order to get a reward.
28
Why are variable ratio reinforcement schedules effective and more resistant to extinction?
If a reward come intermittently and then stops it will take longer to notice it has stopped hence conditioned stimulus remains
29
What is secondary conditioning?
Pairing a now conditioned stimulus with a new neutral stimulus to condition and elicit a response I.e celebrity advertise product
30
What is shaping?
Slowly making reward condition more specific. Complex behaviour so made up of simple behaviour so rewarding simple behaviour will get you closer to ideal behaviour
31
What is successive approximation?
Behaviours that are increasingly close to the target behaviour
32
What is vicarious learning?
Learning through watching others
33
What is attention?
Focus and processing of information from the vast amount of information that is available to you through your senses, memory and cognitive process
34
What is selective or focused attention?
Allows us to attend to only one Stosur of info while ignoring others
35
What is the dichotic listening task?
Listening to one channel on one ear phone a d ignoring the other channel
36
What is the cocktail part effect?
Even if people are listening to one channel they can still notice changes in the unattended channel
37
What is serial processing?
In order to process several stimuli at the same time we need to go through each target one at a time to find the one with both features we are looking for
38
What is executive control?
Mechanism that sets goals a priorities and directs the function of many of our cognitive processes
39
Why aren’t memories very detailed?
We need to extract the general idea of them to apply to multiple situations - memories have to be flexible
40
What is the purpose of working memory?
It’s temporarily holds information so you can continue with a sentence/maths equation etc
41
What’s are the 4 components of working memory?
Phonological loop Visuospatial sketchpad Episodic buffer Central executive
42
Phonological loop
Briefly stores sound information
43
Visuospatial sketchpad
Stores visual and spatial information
44
Episodic buffer
Provides a temporary space where information from subsystem (phonological loop and visuospatial sketchpad) and long term memory can be integrated and manipulated
45
Central executive
Directs the action - controls sequence of actions that need to be performed in the other subsystems
46
What is the serial | Position effect?
U-shaped curve that demonstrates the memory of people at the beginning of a lost and end of a list
47
What is primacy effect? And what does it give evidence for?
Good memory for words at the beginning of the list - evidence for long term memeroy due to rehearsal effect
48
What is the recency effect? And what does it give evidence for?
Good memory for words at end of list. Evidence for working memory, able to access words due to them still being your working memory
49
What do the primacy and recency effect give evidence for?
There are seperate memory systems
50
What does maintenance rehearsal do?
Rote repetitions can shift information from working memory to long term memory
51
What is elaborate rehearsal?
Focus on meaning of information and elaborate on it to remember it
52
Explicit memory
Intentionally retrieve memory
53
What does Implicit memory do?
Influences behaviour without conscious awareness
54
What are two explicit memory tests?
Recall test and recognition test
55
What is a recall test?
Give people a list of words and ask them to recall those words
56
What is a recognition test?
Decide which stimulus or option is the best or most familiar
57
What is anterograde amnesia?
After an accident unable to recalls things from explicit memory but have an intact implicit memory. Can retain information but can’t consciously access it
58
Which area of the brain becomes active in working memory?
Frontal lobes
59
Which areas of the brain are most important for encoding long term memory?
Hippocampus, thalamus and amygdala
60
What is memory consolidation
Turning working memory into long term memory
61
What is the main brain region that turn working memory into long term memory
Hippocampus
62
Can can damage to the thalamus cause?
Impairs encoding of new memories and retrieval of old memories. Can also cause anterograde and retrograde amnesia
63
Role of the amygdala
Encodes emotionally arpusing aspects of stimuli and also helps form long term memories or emotional event s
64
4 reasons for forgetting information
1. Only entered working memory 2. Retrieval failure - info stores in long term memory but retrieval cues are strong enough to retrieve it 3. Decay - information stores but not used and over time decays 4. Interface theory
65
What are the two types of interface theory?
Proactive and retroactive interface
66
What is proactive interface?
Material learnt in the past interferes with recall of newer material I.e can’t recall new phone number because you still remember old one
67
Retroactive interface?
New material interferes with recalls of past material
68
What is content reinstatement?
Make retrieval context as similar as possible to the encoding context
69
What is encoding context?
Place where you do the learning
70
What is retrieval context?
Place where you do the remembering?
