Memory Flashcards
What are memories 3 processes?
Encoding
Storage
Retrieval
What are the types of processing?
Orthographic
Phonological
Semantic
Levels of processing get deep
Retention gets better
When is memory better?
When processing matches between encoding and retrieval
Is memory context dependent ?
Yes if learnt on sea or land better where you learnt it
Remember consistent to mood
What are the characteristics of primary memory ?
Present
Conscious
Retrieval effortless
What are the characteristics of secondary memory ?
Past
Unconscious - permanent
Lot of effort to retrieve
What is selective damage?
Reduced verbal memory spans
Damage to parietal and temporal lobes
What is the word length effect?
Increased syllables decreased recall
Cos of articulately loop- can remmeber what we can say in 1.5s
What is amnesia ?
Ability to take in new information is permanently damaged
What damage did hm have ?
Anterograde amnesia - loss of memories after surgery
In can anterograde amnesics copy tasks?
Yes but when from memory can’t
What isn’t affected for amnesics?
Digit span
Spatial span
Procedural - can learn new skills e.g mirror tracing
Priming - couldn’t remember he done it but could acknowledge he must have cos he’s good at it
What is effected by amnesia ?
Declarative memory
What is declarative memory broken down into?
Episodic (personal)
Semantic (facts and knowledge)
What also isn’t affected by amnesia ?
Implicit memory
Priming and procedural
What is semantic dementia ?
Trouble to remember the meaning of words and concepts
What part of the brain is Semitic dementia associated with?
Lateral temple cortex
Left side
Does vagha think people can acquire new memories ?
Yes , Beth job katie had impaired episodic memory
But completed normal schooling
Goes against declarative memory theory
What is the theory of consolidation?
Hippocampus can bind info and allow it to be encoded into memory
Over time can retrieve without the use of hippocampus
What is retrograde amnesia ?
Affects memories before amnesia
What is the multi trace theory and who is it by?
Opponent to theory of consolidation
Every time you recall memory, you create more links between hippocampus and medial temporal lobe
What is confabulation?
Misinterpreted distorted info
What are the 2 abnormalities in protein development of dementia ?
Senile plaques - excess of b amyloid protein
Neurofibrillary tangles - Mia formed tau protein
Where does b amyloid accumulate first ?
Posterior confidante cortex
And media pre frontal cortex
What does b amyloid cause ?
Hyper metabolism - lower brain activity
Where in the brain do you look for neurofibrillary tangles (tau ) when imaging?
Temporal lobes
Deans it of them correlated with memory loss more than b amyloid
What are the interventions to improve lives of people with dementia?
Engage in motor memory
Increase cues at points of transmission or low activation
Encourage error monitoring
What are the symbols for chromosome 19 (apoe)
E3/E4. E4/E4
What is chromosome 19 responsible for?
Responsible for cholesterol
Protein change
Leads to dementia
What are risk factors for dementia ?
High neuroticism
Chromosome 19,21, 14+1
Poor social network
Above 60 above 80
