Memory Quiz 3/29/23 Flashcards
3 types of learning
verbal, optical, tactile
3 modes of memory
-working memory: call to information
-short-term memory: tagging component, time frame = 30 mins and under (book says)
-long-term memory: psychological change of circuitry in the brain and you’ll remember for a long time
how do you make long term memories
you have to make a stm and it travels to the hippocampus and consolidates it
memory basics:
-acquire info
-retain info
-retrieve system: how we recall it
Contributions to the HM Case Study
1) the medial temporal lobe assists in making stm and ltms
2) mnemonic function occurs in the hippocampus
3) there are different modes of storage
-working
-short
-long
4) HM had difficulty forming explicit memories but was still able to make implicit memories
-explicit (declaration)
-implicit is a strong way of learning
5) HM had difficulty with his semantic memories
6) HM showed improvement on his iq scores
7) in 2004,they took 2,000 slides on his brain, they only found 16 problematic slides
-his brain was working
Procedural memory
type 1 of LTM, the unconscious way that we do things including skills like learning to ride a bike or tying your shoes
Implicit memory (sub category of procedural)
when previous experiences aid in a performance of a task without conscious awareness
declarative memory
also known as explicit memory, this is type 2 of our memory system and refers to memories that are consciously recalled including facts and events
episodic memory
first sub division of declarative memory, a memory of a self-experienced event which includes time, place, and emotion (not defined by an isolated time period)
semantic memory
2nd sub division of declarative memory, refers to the memory of meanings, understandings and concept based knowledge
autobiographical memory
consists of episodes recollected over a person’s lifespan. Based on episodic and semantic
Flashbulb memory
highly detailed and exceptionally vivid snapshot of a moment/circumstance which was surprising and consequential
How many amnesia types are there
5: medial temporal lobe, Korsakoff’s syndrome, alzheimer’s, post traumatic, electroconvulsive shock therapy
Medial temporal lobe
-difficulty forming explicit LTMs
-difficulty forming semantic memory
MAIN REASON: cerebral Ischemia (lack of blood flow, high risk of stoke / amnesia. This is a period of time: months, years, etc, not all of a sudden)
Korsakoff Syndrome
-abuse of alcohol / caffeine (over period of time)
-B-1 (Thiamine) deficiency
-Diencephalon: thalamus and hypothalamus is affected (intelligence and internal regulation)
-Neocortex: if a pregnant individual consumes alcohol, it can stunt the learning ability of the fetus
-Hippocampus: LTM
-Cerebellum: proprioception and motor skills
