AP PSYCH UNIT 7 memory Flashcards
What is memory?
An indication that learning has persisted
What is encoding?
Incoming sensory information is converted for storage
What is the difference between automatic and effortful processing?
That requires attention and or effort (explicit memories)
Some information (your route to school, driving a car) is automatically processed(inexplicit memory)
What is the spacing effect?
Distributing rehearsal is better than practicing all at once ( when studying for a test a student would do better when spreading looking across 7 days than studying the night before the test
What is the testing effect?
Repeated quizzing of information increases the chances it will be recalled. repeated self testing is an effective way to remember things
What is deep processing/semantic encoding?
Processing information with consideration to its meaning
Mnemonic Encoding
is any device or technique used to assist memory, usually by forging a link or association between the new information to be remembered and information (remembering abcs by making it a song)
Method of Loci
a memory enhancement technique that combines visualization with spatial memory of familiar environments in order to quickly recall information (milk in my shoe)
Peg-word system
A memory aid that involves linking words with numbers (one is a gun, two is a shoe)
Chunking
when we divide large pieces of information into smaller units (chunks) that are easier to retain in short-term memory ( PEMDAS)
Hierarchical organization
Complex information broken down into broad concepts categories
Iconic
Iconic memory deals with visual information, holding that information for 1 second
Echoic
short term memory deals with auditory information, holding that information for 1-2 second
STM/Working Memory (what is its capacity and duration)
Capacity 7+/-2 (George Miller, 1956)
Chunking: can increase the capacity of working memory
Duration: approx. 20 sec (brown/peterson, 1958)
Explicit long term memory
Declarative memories which you are consciously aware of acquiring
Implicit long term memory
implicit memory which is the info you are not conscious of acquiring. It includes procedural and conditioned
What are state-dependent memories?
The phenomenon where people remember more information if their physical or mental state is the same at the time of encoding and time of recall. if you learned something while drunk, you will have a higher chance of remembering it if you are also drunk
What are context-dependent memories?
The ability to remember emotional, social, spatial, or temporal circumstances related to an event.
What are mood-dependent/mood-congruent memories?
We usually recall experiences that are consistent with or current mood emotions or moods as retrieval cues
Understand the serial position effect. Know the difference between primacy and recency.
Primacy is the phenomenon where you remember the first items in a list better than the middle of the list
recency cognitive bias in which those items, ideas, or arguments that came last are remembered more clearly than those that came first
What is a flashbulb memory?
A unique emotional moment that created a clear strong persistaent memory, THough vivid and detailed, they are not free from errors( 911, JFK assassination)
Who did research using nonsense syllables? What were his findings?
Herman Ebbinghaus studied rehearsal by using nonsense syllables(icec I cant eat cat)
The more times the nonsense syllables were practiced on day 1, the fewer repetitions were required to remember them on day 2
What is long-term potentiation? What is the role of neurotransmitters associated with long-term potentiation?
a process by which synaptic connections between neurons become stronger with frequent activation
What is the role of the hippocampus and the cerebellum in the storage of long term memories?
Hippocampus -A neural center in the limbic system that processes explicit memories
Cerebellum- A neural center in the hindbrain that processes implicit memories
Define retrieval
Retreieval- information is recovered from memory when it is needed
