Cognitive Psychology Exam 3 Flashcards
The generation effect refers to
the memory benefit of generating information rather than simply observing it
According to the levels of processing theory, memory durability depends on the depth at which information is ___
encoded
Encoding Definition
The process of storing information into long-term memory during the learning experience
Does Repetition help with memory encoding?
No
What does the experiment with reporting all words that start with the letter D show?
There is no difference in the D words remembered regardless of how many times it was repeated (measured with amount of intervening words)
What does the penny experiment show?
You have seen pennies so many times (lots of repetition), but this did not lead to a lot of encoding!
Does having the intent to remember help you remember things? What experiment proved this?
Nope, and the EG checking/pleasantness experiment where some people where warned about the memory test
What else does the EG checking/pleasantness group show?
That depth of processing is important because pleasantness group remembered much better
Levels of Processing Theory
The deeper the stimulus is processed, the better it is encoded
Which is deepest to shallowest encoded? Structural, Phonemic, Category?
Category –> Phonemic –> Structural
___: Is the word in capital letters?
___: Does it rhyme with weight?
____: Is it a type of fish?
Structural, Phonemic, Category
Ways to establish deep processing?
- Survival
- Self-reference
- Imagery
- Understanding
- Organization
- Generation
Which experiment showed that survival is a good way to deeply encode information?
Judging list of words on survival, moving, and pleasantness
Which experiment showed that self-referance is a good way to deeply encode information?
Answering whether words describe you vs words that are commonly used
What does the fact that you remember birthdays closest to your own prove?
Self-reference helps with memory encoding
What did the laundry paragraph experiment show and prove?
Having context before aids with memory –> proves understanding information helps you encode information more deeply
What experiment shows that generating information helps with memory encoding?
Word-pair generating experiment
Three Characteristics of Levels of Processing Theory
Increased elaboration leads to better encoding
Richer network of semantic connections during encoding
More ways to retrieve information during recall
Does testing help with encoding and memory?
Yes, especially after 2 days and 1 week (not so much after 5 minutes)
How is storage/consolidation involved in learning/memory
The strengthening of information in long-term memory after the learning experience
New memories are fragile so you should study with ___
breaks between information to help information consolidate – delay condition
How do we know hippocampal replay assists learning?
Rats replay information during sleep and when we disrupt the hippocampal replay, the rats do not do as well the next day
What happens with the neocortex and hippocampus during sleep?
During wakefulness, input goes into the neocortex and then initial storage. During sleep, hippocampus replays event and puts the memory back into the neocortex
Can the mouse experiment that proves hippocampus is important for learning be generazlied to humans and how do we know?
Yes, because of the Harvard Experiment which did a similair thing. They can shorten ISIs and still get better at the task Then they stay the night in the lab, they are either given a bed and can go to sleep, or they are forced to stay awake. Three days later, we test them with the same task, and see that people who were sleep deprived on the first night, are really bad at the task and the people who slept initially were good at the task
PROVES: sleep is also involved in memory consolidation in humans
What does the Tetris Dream Experiment Show and Prove?
Shows:
- Experts: didn’t improve that much because they are already good
- Novices: improve a lot at tetris
- Amnesics: don’t improve at tetris
Proves: experience-related dreams exist but you may not need a hippocampus for that and it might not be so linked to memory
The principle of ___ states that we encode information along with its context
encoding specificity
Locations, songs, and smells highlight the importance of ____ in long term memory
retrieval cues
Memory performance is enhanced if the type of task at encoding matches the type of task at retrieval. This is called _____
transfer-appropriate processing
Retrieval Definition
The process of accessing information stored
into long-term memory
Tip-of-the-tongue effect
Tip-of tongue is associated with partial information
Based on the standard model of memory why does the tip of the tongue effect exist?
There is not enough spread of activity between nodes
What is the difference between accessibility and availability
Available = the information is stored in memory
Accessible = the information can be retrieved
Does the presentation of cues increase recall and what experiment proves this?
Yes, and the experiment with sentences like “A lampshade can be used as a hat.” It was difficult to remember all of these without a retreival cue but when given the word lampshade, people more easily remembered the word hat.
How does the tip of the tongue effect relate to retrieval cues?
If something is on the tip of your tongue, you may just need a good cue!
What exactly is a cue?
Cues are simply nodes in a memory’s network
Is the context of studying important and how do we know this?
Yes, and through the studying underwater vs on land experiment which shows that if you study and are tested in the same context, you will preform better.
Encoding Specificity Definition
Matching context between encoding and retrieval assists performance
What does the experiment with studying with noise/without noise prove?
Context is important
How does encoding specificity relate to the standard model of memory?
Memories are distributed networks of associations and context is just another set of associations.
What is a more succesful retreival cue? Rhyme or Meaning
Depends on which one was used during encoding – transfer-processing approach
Transfer-appropriate processing approach
Better performance when the type of processing matches during encoding and retrieval
Can transfer-appropriate processing approach be explained through associative networks?
No, deeper processing does not always result in better retrieval which goes against the levels of processing theory.
What is the difference between proactive interference and retroactive interference?
Proactive interference – information you learned earlier on interferes with remembering something now
Retroactive interference – information you learn later that interferes with the remembering the initial information
What does the proactive interference experiment show and prove?
People had trouble with retrieval and a possible explanation may be that there is competition during retrieval because each session may create one large network
What was the retroactive Interference experiment and results?
Have people study a list of noun pairs in multiple sessions and the first part of the list is the same for both sessions but not the second part. In the test phase, they are supposed to fill in the second word for each pair but only from the first session.
Control condition: use completely new list in session 2 and in tes condition they ask them to fill in nouns from session 1 → separating out contexts
Results: Experimental condition had MUCH worse performance due to retrieval competition
What is Constructive memory?
Memories are not a carbon copy of the past
Prone to revision and error
Does retrieval cause changes?
Can retrieval induce forgetting?
Yes, for the items that aren’t rehearsed as seen in the Grocery and Games Experiment
What is an alternative explanation for retrieval inducing forgetting?
Blocking: Practiced words occupy the ‘response channel’ (they come to mind so quickly that they block the unpracticed words)
What are the conclusions on retrieval induced forgetting?
Memories are constantly in swing
Elements can be suppressed and activated
Retrieval biases towards recent goals
What are the conclusions on Retrieval in general?
The effectiveness of retrieval depends on
what you do with information
Retrieval is error prone (interference)
Retrieval can change memories (retrieval induced forgetting
What does neuroscience say about retreival induced forgetting vs blocking?
we can see with MVPOA that, the brain
What type of memory does this refer to: A person’s knowledge, experiences, and expectations contribute to what
gets remembered?
Constructive
What is an everyday memory?
an Everyday Event
Two important considerations for autobiographical memories
Multidimensional
Some autobiographical memories are remembered better than others
What does it mean for a memory to be a multidimensional memory?
The memory includes several sensory-modalities, the memory takes place in three-dimensional space, there are thoughts and emotions associated with the memory
What makes certain events memorable?
More special events, you are either really happy or really upset about it
What autobiographical memories remain?
Memories are stronger for events that are distinct from our day-to-day experiences
and remininsce bump (early adulthood memories)
Why is there a reminiscence bump in early adulthood?
- Time of self-image formation
- Time of rapid change with new events
- Time where important cultural events occurs
How do we know emotion affects memory?
experiment with neutral, negative, and positive pictures of animals, also activity in the amygdala
Does the experiment with the animals prove that the amygdala is necessary for emotional memories to be remembered better than neutral ones?
no
What does the Amygdala Experiment with Emotional Memory show and prove?
Group 1: typical amygdala function
Group 2: impaired amygdala function
Shows: participants with normal amygdala remembered scary photos better than other photos. People with damaged amygdala couldn’t remember the scary photo better
Proves: amygdala activation is important for consolidating emotional memories
Flashbulb Memories defintion
Any memory where a person
remembers the circumstances
surrounding how they heard about the event
When do flashbulb memories typically occur?
Under Highly Emotional Circumstances
What are flashbulb memories associated with?
Overt narrative rehearsal – a person typically reports many vivid details long after the event occurred
Are flashbulb memories more accurately remembered than regular memories?
Nope
If flashbulb memories are emotional and distinctive, why aren’t they remembered more accurately
Constructive Nature of Memory
What does it mean for memory to be inherently constructive?
Affected by a person’s
knowledge, expectations, and
experiences
Remembering something may
distort or change the memory
based on new information.
