Unit 3 Lecture Notes Flashcards
DEMO: rate what a word means to you vs. count the number of “e’s” in a a word
what concept did this demonstrate?
semantic encoding is more effective
what are the 3 processes of memory?
encoding, storage, retrieval
what can the 3 processes of memory be compared to?
a computer
what are the 3 types of encoding?
structural, phonemic, semantic
what is structural encoding?
being given information, but not processing it or soaking any of it up
what is phonemic encoding?
receiving information by hearing; listening to words
what is semantic encoding?
thinking of the meaning of words; finding personal relevance to chunks of infomation
what are the 3 types of storage?
sensory, short term, long term memory
what are the 3 types of sensory memory?
iconic: vision, storing information in a visual way
echoic: auditory messages echo in memory
haptic: touch/tactile
what type of memory storage is limited by attention and lasts only a few seconds?
sensory memory
e.g. while walking, one does not remember trees because they weren’t paying attention to them
what type of memory storage is limited by the 7 items and lasts 30 seconds without rehearsal?
short-term memory
what type of memory storage has unlimited storage capacity?
long-term memory
what are the two types of long-term memory?
declarative, non-declarative
what are the two types of declarative memory
semantic, episodic
what are the three types of non-declarative memory?
procedural, classical conditioning, priming
what is semantic memory?
facts
what is episodic memory?
episodes in life story
what is procedural memory?
remembering a process; how to do things
what is classical conditioning memory?
learned associations
e.g. no one is born with fears
what is priming memory?
current thoughts influence memory
what did henry’s story of life threatening epileptic seizures help scientists discover?
the removal of part of the hippocampus results in the inability to store long-term memories
TYL: Types of Long-Term Memories
omar recalls his trip to Washington D.C.
declarative; episodic
TYL: Types of Long-Term Memories
a snakebite at the age of three has left peter afraid of snakes
nondeclarative; classical conditioning
TYL: Types of Long-Term Memories
cari can name all of the former presidents of the U.S.
declarative; semantic
TYL: Types of Long-Term Memories
tom remembers his girlfriend as less attractive after thinking of models
nondeclarative; priming
TYL: Types of Long-Term Memories
tamara remembers her first date
declarative; episodic
TYL: Types of Long-Term Memories
cori remembers how to ride a bike
nondeclarative; procdeural
TYL: Types of Long-Term Memories
manuel rembers how to play the piano
nondeclarative; procedural
TYL: Types of Long-Term Memories
kirsten knows a poem by heart
declarative; semantic
TYL: Types of Long-Term Memories
little saima can recite her phone number
declarative; semantic
DEMO: listening to list of random words; which ones were the most remembered?
the first and last
idea: primacy and recency effects
what are the types of retrieval?
serial effects: primacy and recency effects
what is the primacy effect?
first parts that are learned are remembered the best because of rehearsal
what is the recency effect?
the last parts that are learned are remembered because of less interference
which serial effect is stronger?
primacy effect; rehearsal is a very dependable memory strategy
DEMO: listed words associated with sleep demonstrated which idea?
schemas
what are the five types of false memory
schemas, misinformation, misattribution, personality, heavy marijuana use
what are schemas?
small connection nodes on main neurons are activated
what is misinformation?
intentionally given false information
e.g. attorney mentions a stop sign in a video; jury remembers seeing a stop sign even if it wasn’t there
what is misattribution (of source)?
remembering information rather than the source
harmful if the source is unreliable
what is personality (susceptibility)?
certain people are more susceptible to false memories
e.g.people w/ alien abduction memories are more susceptible to false memory
how does heavy marijuana use impact false memories?
individual remembers actions that they didn’t do
infants have good short term memory, but lack long term memory
what parts of the brain are developed?
infantile amnesia
striatum develops faster than hippocampus
what is humans’ memory peak and how can one protect their memory and cognitive function beyond this age?
25 years old; exercise and social networks
what is a reminiscence bump and what is the leading theory?
elderly people remember the most from their years in their 20s.
theory: most of the “firsts” in life are experienced in their 20s
why do memory enhancing pills only work for elderly people?
at this time of life, elderly people have less brain cells.
the pills only supply acetylcholine to the little remaining brain cells.
what is a common cause of amnesias?
traumatic events
