Memory Flashcards
Memory
The capacity to retain and retrieve information
Recall
Ability to retrieve information which has been learned earlier
Recognition
Ability to identify previously encountered information
Relearning
Effort is saved in having learned something before
Information Processing Model
Memory and mind are like a computer
Encoding
Process of transforming the info received through the senses into memory
Levels of Processing
Different levels of processing that impact encoding
Shallow Processing
Structural encoding - emphasizes the physical structure of the stimulus
Intermediate processing
Phonemic encoding - emphasizes what a word sounds like
Deep processing
Semantic encoding - emphasizes the meaning of verbal input
Sensory Memory
- Retains for 1-2 seconds
- Decides if stuff is worth processing
- Iconic: fast-decay of visual info
- Echoic: fast-decay of auditory info
Short Term Memory
- Holds limited amounts of info
- Working memory
- Retains info for 15-20 secs
- Pattern recognition: compares to info already in long term memory, goes to long term or decays or is lost
Long Term Memory
- Longer storage for minutes to decades
- Storage depends on synaptic connections
- Organized by schemas and semantic networks
Explicit (Declarative) memory
Act of consciously or intentionally retrieving past-experiences (Knowing “that”)
Episodic (Explicit) Memory
Experienced events, personal recollections that allows us to both recollect the past & imagine the future
Semantic (explicit) memory
Facts, rules, concepts, general knowledge
Implicit Memory
Unconscious influence of past experiences on later behavior & performance
Procedural (Implicit) Memory
Acquiring skills due to practice; knowing “how” to do things
Priming (Implicit) Memory
Increases identification of objects/words based on recent exposure to other stimuli
Serial Position Effect
More likely to remember first and last few and not the middle
Primacy Effect
Memory of beginning pieces of list
