Q

what is memory?

A

our ability to retain and retrieve skills and knowledge

2
Q

what are the 3 phrases of memory?

A

encoding - processing (consolidation)
storage - retention
retrieval - remembering

3
Q

what is reconsolidation?

A

every time we activate a memory, we store it again for retrieval
(stored memories may differ from original version)

4
Q

how does long term storage work?

A

results from forming new connections and strengthening connections between neurons

5
Q

what is long term potentiation?

A

strengthening of a synaptic connection, making the postsynaptic neurons more easily activated by presynaptic neurons

6
Q

what different parts of the brain are used for LTM?

A

hippocampus - encoding
medial temporal lobes - forming new memories
visual and auditory cortex - reactivated when remembering a visual or auditory memory

7
Q

what are the different types of memories?

A

sensory memory
short term memory (working memory)
long term memory

8
Q

what do STMs do?

A

hold info until it is stored or forgotten

9
Q

what is your working memory?

A

short amount of info can be stored and manipulated with working memory

10
Q

what is chunking?

A

we put together meaningful units to easily remember strings of numbers or letters
ex - phone number (xxx-xxx-xxxx)

11
Q

primacy vs recency

A

primacy - remember first part of list better
recency - remember last part of list better (working memory)

12
Q

what is maintenance rehearsal?

A

repeating over and over

13
Q

what is elaborative rehearsal?

A

encoding in meaningful ways and anaylizing it

14
Q

what is explicit memory?

A

episodic memory (autobiographal)
semantic memory (facts)

15
Q

what is implicit memory?

A

procedural memory (muscle memory)

16

17

anterograde - can’t remember after the trauma/injury

19
Q

what is source amnesia?

A

we know something but don’t know how we know
ex - childhood amnesia

20
Q

what is dementia?

A

deterioration of thinking, memory, and behavior
Alzheimer’s disease
-plaques form in brain
-ACh is very low
-genetic predisposition

21
Q

what is PTSD?

A

intense memories of traumatic events and easily triggered to remember them
(flashbacks)

22
Q

what can happen with PTSD?

A

some might have trouble remembering the traumatic event
other experience STM loss
some experience dissociative amnesia
those with PTSD have diminished hippocampal volume

23
Q

what is HSAM?

A

highly superior autobiographal memory
highly accurate and detailed memory for autobiographal events

24
Q

what are false memories?

A

when someone imagines event, mental images of details form
misattribute source of dream

25
Q

what is one issue with false memories?

A

eyewitness accounts might not be accurate
