General Psychology Psy 101 Chapter 5
Immediate, very belief recording of sensory info. Consists of registers, where we temporarily store incoming sensory info.
Visual sensory register, holds an exact copy of visual input, but for less than 1 sec.
full report procedure, report entire matrix, partial report procedure, report 1 row based on tone
Short Term (STM)
Recognized info. from sensory memory enters consciousness, testing capacity of STM, memory span task -7 +/- 2 ” chunks” of info. Testing duration of STM, Duration task, 30 seconds. Maintenance Rehearsal, keep info in STM
Long Term Memory (LTM)
store info for long period of time, unlimited capacity.
requires conscious recall
Does not require conscious recall, implicit procedure, memory for performance of actions or skills
Inability to form memories after trauma
Inability to remember events before trauma
Anterograde Amnesia for explicit memory only, can form new implicit memories
What did we learn?
explicit/ implicit memories processed in different parts of brain. STM and LTM 2 different stages
STM & LTM
Free recall task, primacy effect- LTM, Recency effect STM
Level of processing theory, LTM best info processed semantically, Next best for info processed acoustically , worst info processed physically
Relating new info into info already in LTM, more retrieval cues.
Self- Reference effect
Elaborate on new material by relating to it yourself
memory aid, requires elaborative rehearsal
Method of loci
associated with locations in a room
studying past point of initial learning
retrieve info learned earlier ( No retrieval cue to help remember)
Recognize info learned earlier .
info never entered LTM
info not accessed decays from LTM
older info interferes with retrieval of newer info
Newer info interferes with retrieval of older info
Cue- dependent theory
info avaiable, but cues necessary for retrieval arent avaliable
frameworks for knowledge; help to organize world, people “misremember” info in ways that are consistent with schemas
attributing an event to the wrong source
distortion of memory by exposure to misleading information
loftus & palmer (1974)
watched traffic accident film ” smashed” or “hit”. Smashed, higher speed estimates & more likely to report seeing broken glass
