Cognition - Information Processing Model Flashcards
Memory
Human capacity to register, retain, and remember information.
Information processing model
Encoding, storage, and retrieval.
Encoding
Process of putting information into the memory system.
Storage
Retention of encoded information over time.
Retrieval
Process of getting information out of memory storage.
Levels of processing theory or semantic network theory
Ability to form memories depends upon the depth of processing.
Shallow processing
Structural encoding emphasizes structure of incoming sensory information.
Deep processing
Involves forming an association or attaching meaning to a sensory impression and results in longer-lasting memories.
Self-reference effect or self-referent encoding
Involves forming an association or attaching important/relevant more deeply, making it easier to recall.
Sensory memory
Holds external events from the senses up to a few seconds.
Visual encoding
Encoding of picture images.
Iconic memory
Momentary sensory memory of visual stimuli.
Acoustic memory
Encoding of sound.
Echoic memory
Momentary sensory memory of auditory stimuli.
Selective attention
Focusing of awareness on stimuli in sensory memory that facilitates STM encoding.
Automatic processing
Unconscious encoding of information about space, time, and frequency that occurs without interfering with thinking about other things.
Parallel processing
Involves several information streams simultaneously.
Effortful processing
Requires attention and conscious effort.
Feature extraction (pattern recognition)
Finding a match for new information in sensory storage by actively searching through long-term memory.
Short-term memory (STM)
Working memory, 20 seconds before forgotten.
Rehearsal
Conscious repetition of information to either maintain information in STM or to encode it for storage.
Maintenance rehearsal
Repetition that keeps information in STM about 20 seconds.
Elaborative rehearsal
Repetition that creates associations between the new memory and existing memories in LTM.
Chunking
Grouping information into meaningful units increasing the capacity of STM.
