Atkinson-Shiffrin Model
sensory memory, short-term memory, long-term memory
information processing model
encoding, storage, retrieval - like a computer
Connectionism model
memories are products of interconnected neural networks
levels of processing
deeper processing = more important, shallow = short term & unimportant
sensory memory
limited by time, infinite storage in the moment
Working memory
short term - limited by number (7 = George A. Miller)
George A. Miller
made famous the phrase: "the magical number 7, plus or minus 2" when describing human memory
Imagery memory
encode memory both semantically and visually -mnemonic devices
self-reference effect
Semantic memory ↑ = relatability ↑
rosy retrospection
The tendency to rate past events more positively than they had actually rated them when the event occurred.
Chunking
Combining small pieces of information into larger clusters or chunks that are more easily held in short-term memory.
Hierarchies
chunking complexity ↑
parallel processing
Automatic & implicit (time/setting/muscle memory) VS Episodic & semantic (facts) tracks
primacy effect
better recall for items at the beginning of a list, longer term than recency
recency effect
tendency to remember words at the end of a list especially well - still in working memory - short term
effortful processing
requires attention and conscious effort - in the frontal lobe & hippocampus
implicit memory
unconscious memory - cerebellum & Basal Ganglia
memory trace
mental path by which some thought becomes active - experience strengthens pathways & does not edit neurons
long-term potentiation (LTP)
an increase in a synapse's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory. - Glutamate & CRED & sleep increase
Amnesia
loss of explicit memory - can learn implicitly
Left hippocampus damage
disrupted verbal memory
right hippocampus damage
disrupted visual memory and locations
infantile amnesia
Cerebellum alone records memory - implicit experiences
basal ganglia
structures in the forebrain that help to control movement
Recall vs. Recognition
fill in the blank tests vs. multiple-choice tests
Priming
the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response
mood, state, & context
Daniel Schacter
7 sins of memory
absent-mindedness, transience, blocking
3 sins of forgetting: (1) encoding failure (2) storage decay over time (3) can't access stored info (tongue tip)
Misattribution, suggestibility, and Bias
3 sins of distortion: (1) source mismatch (2) misinformation effects memory (3) memories influenced by belief
Persistance
the intrusive recollection of events that we wish we could forget
Herman Ebbinghaus
serial position effect (primancy & recency) & the forgetting curve
proactive interference
the disruptive effect of prior learning on the recall of new information
retroactive interference
the disruptive effect of new learning on the recall of old information
imagination inflation
memory & imagination areas are provoked at the same time - creating false memories
source amnesia
lack of source context, just the event - (not misattribution & source mismatch)
True memory vs imagination
more detail & less of gist
positive transfer
when old information facilitates the learning of new information
Elizabeth Loftus
misinformation effect (eyewitness testimony) question influence imagination inflation
Noam Chomsky
language = innate
George A. Miller
short term memory has the capacity of about 7 (+/- 2) items.
Wolfgang Kohler
chimpanzee experiments Insight learning divergent, creative thinking
Robert Sternberg's intelligence theory
Successful intelligence; devised the Triarchic Theory of Intelligence (analytical, practical, and creative)
Formal reasoning
bottom up
Cognitive Bias
The misinterpretation of information as a result of a faulty or rigid heuristic
Representative Heuristic
placing stimulus into a category based on understandings and schemas that are learned by ear (not experienced)
Availability Heuristic
Using experience, or most memorable information to place a stimulus in a category
Creativity
Novel & valuable - Frontal Lobe - divergent
Convergent thinking
narrowing solutions - left partial lobe
Robert Sternberg's creativity theory
5 - VIIAC Expertise Imagination Venturesome personality Intrinsic motive Creative environment
informal reasoning
top down - Heuristics & cognitive bias
Anchoring Bias
(Cognitive Bias) a tendency to fixate on the first information
Confirmation bias
(Cognitive Bias) a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence
Hindsight Bias
(Cognitive Bias) the tendency to believe, after learning an outcome, that one would have foreseen it
Rigidity
(Cognitive Bias) Rejecting new ideas in favor of our own
functional fixedness
the tendency to think of things only in terms of their usual functions; an impediment to problem solving
mental fixedness
Using previous success to block outside the box thinking
mental model
a specific situation that is represented in a person's mind with two or more mental concepts interacting
Syllogism
(formulaic) A form of deductive reasoning consists of a major premise, a minor premise, and a conclusion. like a mental formula for solutions
Diagnosis
(formulaic) eliminating wrong answers
A.I.
(formulaic) using formulas to form a solution
intuition
an effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning
automatic processing
unconscious encoding of incidental information - low effort
framing
the way an event is posed
Intelligence
Ability to adapt and learn with experience and concepts
Charles Spearman
creator of "g-factor", or general intelligence, concept - there is one intelligence & and each area interacts with the other. A score of one concept is indicative of another
L.L. Thurstone
attacks spearman's g factor with 7 intelligences
Flynn effect
The rise in average IQ scores that has occurred over the decades in many nations
Howard Gardner
8 intelligences!!!!! Savant Syndrome & islands of brilliance
Mental set
a tendency to approach a problem in one particular way, often a way that has been successful in the past
Alfred Binet
mental age & earliest measuring of intelligence

universal grammar
Noam Chomsky's theory that all the world's languages share a similar underlying structure
language acquisition device
Chomsky's concept of an innate, prewired mechanism in the brain that allows children to acquire language naturally - not like other learned things by operant conditioning (skinner)
Broca's aphasia
inability to produce speech - but can sing [frontal lobe]

bilingual advantage
bilingual children who learn to inhibit one language while using the other are better able to inhibit their attention to irrelevant information - stronger overall brains - creativity up
Outcome vs. Process simulation
process simulation is more effective (focusing on process = success at task up)
Language
our spoken, written, or signed words and the ways we combine them to communicate meaning
general intelligence (g)
a general intelligence factor that, according to Spearman and others, underlies specific mental abilities and is therefore measured by every task on an intelligence test
