Chapter 8 Flashcards
what is memory
the retention of information over time
episodic memory
ex: last birthday
semantic memory
ex: the largest mountain in Austri
Procedural memory
eX: how to ride a bike
3 systems of memory
sensory memory –> short term memory –> long term memory
how fast in unrehearsed information lost?
15-30 seconds
sensory memory
- sensory buffer before transfering to Short term memory
- these are your senses (iconic or visual, echoic - auditory)
sperling’s test of iconic memory
found that people access to all 12 letters
- unable to recall all letters because memory fades
-
STM stands for
short term memory
Short Term Memory
related to working memory, however not the same
- memory coding happens here
- retains 7+/- 2 pieces of information
chunking
organizing material into meaningful groups
rehearsal
the rehearsal of information in short term memory
long term memory
life learned facts, experiences, and skills
primary and recency effects
probability of remembering is shaped like a U over time
- primary effect is first dip and is likely due to long term memory
- rise in probability of remembering is called the recency effect and is likely due to the short term memory effect
encoding
active process because we would be overloaded otherwise
- automatic processing vs. effortful processing
(unconscious vs conscious; minimal vs high attention; frequency vs. episodic)
