Final Exam 10/4-11/4 Flashcards
Describe the relationship between proessing and encoding information
The deeper processing, the better you are at encoding information.
Example: attatching semantic understanding to words that you hear, rather than more surface level understadning
What does State Depending learning assert?
What does that conclude?
Levels of Processing shows that mental manipulations can affect encoding
- state of mind, body during encoding, recall
We are not only learning the information, but also the context in which it is presented
Describe the difference between recall and recogition
Recall
- Given a cue, remeber infromation without prompting
- Involves memory search
Recognition
- Given infromation – is this something presented previously
- Involves familiarity
Define Explicit Memory
- Conscious recollection of past events typically revealed through recognition or recall tasks
- Memory with awareness
Define Implicit Memory
- Memory without awareness
- Influence of past events on behaviour wihthout consciousness
- “Subliminal”
What are the three methods that test implicit memory?
- Stem Completion
- Mere Exposure Effect
- Priming
What do the three methods that test implicit memory, measure specifically?
All three involve measurment of memory without conscious awareness
- Behaviour is influenced without subject’s knowledge
What is mere exposure a form of?
Priming
Define Priming
Any situation in which one’s current behaiour is infleunced by exposure to previous information
What are the different types of priming?
1) Repetition priming (same stimulus twice)
2) Lexical priming (changing words perceptual appearence)
3) Associative priming (generate associate, then shown said associate)
4) Semantic Priming (“doctor” primes the presentation of “nurse”)
Describe Implicit Mempry Theory #1
Seperate memory systems
- Implicit memory is based on perceptual representations
- Explicit memory is based on episodic system, which analyzes meaning
- Biologically plausible
Describe Implicit Memory Theory #2
A single system.
Implicit and explicit memory tasks impose different processing requirements
- Implicit tasks are perceptually driven
- Explicit tasks are conceptually driven
Describe Implicit Memory Theory #3
- Implicit memory are automatic processes (procedural)
- Explicit memory requires a delcarative process. Rewuire conscious awareness.
How do we remeber details?
They might not all be in there consciously, but we seem to be able to retain infromation below the level of consciousness
Its hard to say which theory is correct
Describe retrograde amnesia
Memory loss for events before the onset of the syndrome
Describe Anterograde Amnesia
- Memory loss for events after the onset of the syndrome
- Issues of encoding or retreival
- Procedural memory
Decribe patient HM’s performance on implicit memory tasks
- Similar to controls
- Skill learning was not imparied
Describe Anterograde Amnesia in terms of encoding information
Anterograde Amnesia is a failure to encode new information
- Explicit memory fails to get in
- Implicit memory system is functional
What are some reasons for “Memory Errors”
- Interference
- Source Monitering
- Suggestibility and Misinformation
- Updating or social pressure
Describe Proactive Interference
Old information in LTM interferes with the new material of the same type that you are trying to learn
Example
- Learn word list A. Then learn word list B. Tested on b.
- Memory is worse on list B than if you only learned list B without having learned list A first
How can proactive interference be mitigated?
Proactive interference is specific to the nature of the information being learned
Example
- Learn word list A. Then learn a list if numbers B. No interference effect
Describe Retroactive Interference
Learning new information could affect how old infomarion is recalled
Describe Content Interference
Learning and retaining an association is more difficult if the first member of the pair is used in more than one pair
What are other types of memory erros?
- Details are oftne lost, gist is retained
- Remebering things that aren’t there
What overarching things might infleunce memory errors?
The organization of memoery, and other types of prior knowledge influences memory errors
What are the 5 harachteristics of Schemas?
- Organized knowledge structure
- Reflect learned knowledge an expericnece
- Embedded structure
- Variables & default values
- Malleable
What are Schemas essential for?
Understanding and remebering
What are the interim colclusions on Memory errors
Memory Erroes can be caused by thrre factos
- delay
- Interence
Describe Flashbulb memories
Certain emotionally charged events that can never be forgotten
Describe Spreading Activation in the context of false memories and memory errors
We have a very highly interlinked associative network of things that we know.
When certain cells related to certain concepts are activated in the brain, it sends associative signals to other things that are related in semantic meaning.
Describe the following aspects of LTM
- Duration
- Capacity
- Charachteristics
Duration: A lifetime, frequently without intervening practice
Capacity: No known limit
Characteristics: Meaningful relationships preserved (e.g., semantic associations; procedural orders; visual organization)
What factors affect long-term memory
- Recency & primacy
- Intentional vs. incidental processing
- Interference – similarity between and timing of different materials that are to be remembered
- Frequency effetcs – comonly occuring stuff is easier to remember than uncommon stuff
- Retention interval (duration and type of intervening activity)
- Task - recognition is generally better than recall
- Retroactive and proactive interference
- Motivation
- Activity at study time - levels of processing
- Organization of material
- The associative nature of LTM
What does Spreading Activation Theory Assert?
- Specific concepts, experiences or ideas are stored in memory via areas of neural activation
In Spreading Activation Theory, how are concept nodes activated?
Concept nodes can be activated by input from linked concept nodes
How does activation spread in spreading activation theory?
Activation spreads from one concpet to related ones (closer associations = shoter lines)
In Spreading Activation Theory when does a concept node fire?
Each concept node fires when it recieves sufficient activation to reach a threshold
What did Whitten & Leonard aim to answer in their study?
- How does memory change as a result of a recognition test?
- What effects do the incorrect answers on a recognition test have on subsequent recall?
What did Whitten & Leonard’s experiment conclude regarding testing, recall and recognition?
- One recall of an item increases the probability of subsequent recall or recognition
- The increment in memory is inversley related to the difficulty of the initial test
