10 Cards in this Set

  • Front
  • Back
Sensory memory vs. STM vs. LTM
SENSORY: temporary, w/visual images (iconic) lasting about 1/2 sec and sounds (echoic) lasting up to 4 sec, selective attention puts in STM; STM: works to process ongoing info and store memories up to 30 sec (primary and working mem); LTM: neither limited in capacity nor duration (recent/immediate: 2 wks, and remote/LT: 2 yrs or more), REM sleep may help
Rehearsal vs. Chunking
REHEARSAL: deliberate repetition, usually acoustic, of information to enhance STM or enhance its transfer into LTM; CHUNKING: involves transforming separate items into meaningful units/lists to increase ability to remember them (STM) as most people can only remember 5-9 unrelated items
Iconic vs. Echoic
ICONIC: visual images (sensory mem); ECHOIC: sounds (sensory mem)
Recent vs. Remote Memory
RECENT/Intermediate: 2 wks; REMOTE/Long-Term: 2 yrs or more
Zeigarnik Effect vs. Redintegration
ZEIGARNIK EFFECT: when problem-solving comes to impasse, brain keeps working UCS until solution is obtained; REDINTEGRATION: when something unlocks a rapid chain of memories (e.g., childhood smell)
Semantic vs. Episodic memory
DECLARATIVE MEMORY: (1) SEMANTIC=memory of meanings of words, facts, and how they related to each other, (2) EPISODIC: memory of autobiographical events
Procedural vs. Declarative memory
PROCEDURAL: aka implicit, nondeclarative, involves recollection of skills, physical operations, and procedures remembered UCS w/o CS awareness, not stored w/respect to specific times/places; DECLARATIVE: aka explicit, CS recollection of information or experience (divided into Semantic and Episodic)
Long term potentiation
The physiological process by which STM become LTM (repeated stimulation of synapse leads to chem and struct chanages in receiving dendrite…)
Retroactive vs. Proactive inhibition
RETROACTIVE: Recently learned material interferes w/ability to recall material learned in past; PROACTIVE: Previously learned material interferes w/ability to learn or recall new material
Method of loci, Pegword system, Word association, Substitute word system
METHOD OF LOCI: visual image of items on list and placing as one mentally walks through room; PEGWORD SYSTEM: memorizing visual images that can be pegs on which to hang ideas (e.g., one is bun, two is shoe); WORD ASSOCIATION: forming words or sentences w/first letter of items being memorized or stories; SUBSTITUTE WORD SYSTEM: breaks down word into parts and substitutes more familiar words that can be visualized (e.g., catabolize=cat, ball, eyes)
