encoding

5 tests: 1)homonymy recognition and rhyming 2)ability to match pictures by sound 3)matching words to pictures 4)matching pictures to words 5)evoke sound from printed words/read aloud

hypothesis: left will excel, right will not

left hemisphere seperated

able to match auditory cues to pictures and make auditory cues from pictures. Able to match alliteration and rhyiming well. Able to read aloud

right hemisphere seperated

can match auditory cues to pictures/cannot make auditory cues from pictures. Unable to effectively match alliteration and rhyming words reliably. When given tests second time, sporadic shifts to lh, along w imporvement in performance. Can match sound to spelling but not spelling to sound.

conclusion: right hemisphere is necessary for encoding

hypothesis: presence of DA would not affect semantic recall but would affect episodic encoding. Compensation would be present under DA conditions.

during encoding semantic processing=more elaborate recall/memories. Recall ing both groups uses very little energy, while encoding requires a lot of energy.

elderly

failure of emantic and episodic memory to work together. not encoding new episodic memories=no recall of new mmories.

DA young=FA young. compensatory memory. scaffolding.

compensation is deliberate. consistent w hypothesis

young

no issues with encoding or recall of new memories

content addressable/retrieved without search

compactly store associations between associations

"lossy" storage=forgetting

firing patterns of neurons like that of light making holographic images

can be used to describe associative memory

two uses: cognitive psych and mathematical encoding/decoding operations
