Cognition Flashcards
1
Q
Information-processing model of memory
A
like a computer
3 parts to it
1. Encode the info [like typing it into a document] [or cataloguing and identifying a new book]
2. Store the info [like saving a document] [or placing a book on a shelf]
3. retrieve the info [like getting it from the hard drive] [or retrieving a book from the shelf]
2
Q
effortful processing
A
giving thought and paying attention to new infromation
3
Q
automatic processing
A
stimuli that are encoded without any effort
4
Q

used by the brain to encode multiple things simultaneously
5
Q
Deep Processing
A
consciously adding meaning or making connections with information we are taking in
ex. B words
6
Q
shallow processing
A
not deep, no meaning attached/lack of placement in a relevant context responsible for forgetfulness
ex. A word
7
Q
maintenance rehearsal
A
simple repetition to encode what we are taught
shallow processing
8
Q

Critical Period/Sensitive Period
An important developmental for learning language
After puberty, language can not be fully learned
THIS IS NOT A FOREIGN LANG, BUT A FIRST ONE
Based on case studies
Wild Children
BIlingual
Isolated CHildren
Deaf Children
138
Wild Children (Cirtical Period)
Extremely rare

India 1970s
139
Isolated Children (critical Period)
Very rare
Neglected and abused kids
Isabel- 6 yes
Genie 14 yrs
140
Bilinguals (Critical period)
Children who learn a second language can speak it without an accent but adults have accents
141
Deaf Children of Nicaragua (Critical Period)
Learn sign language as kids tend to be more fluent than adult learners
Kids came up with own language
142
Nativists Theories
```
Nativist=innate
Nature
Humans are predisposed to learn language [prewired]
Noam Chomsky- MIT
LAD
Universal Grammar
```
143
Language Acquisition Device
LAD
Born with system for processing and producing language
evidence: deaf kids in Nicaragua
supports Nativist Theories
144
Universal Grammar
all languages have similarities/can learn form other cultures
supports Nativists theories
145
Learning Theories
Big Forehead Skinner and Bandura (operant and social)
Nurture
Language learning happens through observation and conditioning
when a parent hears kid speak THEY FREAK OUT AND PRAISE THEM SO MUCH! this reward encourages more speech
kids imitate their accent and vocab (bad word)
146
Problem with learning Theories of Language Acquisition
Kids are rewarded for incorrect speech, but they learn to correct themselves
147
Cognitive Theories of Language Acquisition
Combines nature and nurture
Predisposed for language
innate system but XP is required for development
-Critical period
Thinking and Language are linked and as cognitive skills develop so does lang
148
Linguistic Relativity/ the Whorfian Hypothesis
LAnguage influences thought
Supportive evidence
use of he for humanity --> it's a man's world
Propoganda
149
Opposing Evidence for Linguistic Relativity/the Whorfian Hypothesis

New Guinea natives- only 2 color words but still able to recognize difference between colors
Still thought w/o word
150
Surface vs. Deep Structure
Noam Chomsky
Each sentence has one surface structure, but multiple deep structures
HUmorous sentences
ec. They are frightening monkeys
Mrs. Nixon found drunk on white house lawn
Last night I shot an elephant in my pajamas
151
Reading
starts out controlled but becomes automatic
English ---> alphabetic system
letters correspond to sounds and are units of writing
good readers are automatic
152
Phonemic Awareness
```
part of reading
e with u
o
e with bar
look
```
153
Stroop Effect
Kind of interference
| Colors and words don't match up, hard to read
154
superordinate categories
broad and overarching
155
basic categories
specific examples from the superordinate
156
subordinate categories
specific examples from the basic
157
Formal Concepts
Defined by very specific rules
| ex. a square
158
Natural concepts
Formed from everyday experiences, do not have a fixed set of defining features
have typical characteristics and are often based on prototypes
159
Incubation
leave problem for a while after brainstorming to allow the mind to work on it without conscious effort
can lead to further insight upon return
160
Metacognition
reflecting and thinking about one's own problem solving strategies
161
Insight
```
A correct solution that suddenly comes after struggling with a problem
#insightlearningwithmonkeys
```
162
Trial and Error
Try a bunch of stuff and eliminate what doesn't work
163
Functional Fixedness
Trapped in only seeing certain uses for an object
Potato = food, not emergency gas cap
Paper clip not for earring s
164
Mental Set
Fixation on one particular way to solve a problem
opposite of Sharon High Math Teachers
students often get trapped into only approaching something in one way
165
Implicit Assumptions
Assume that there are rules limiting us even when they do not exist
Ex. Nine dot problem
166
Algorithm
Step-by-step method that ensures a solution as long as each step is done properly
ex. Chain Rule
167
Heuristics
short cuts in problem solving
rule of thumb
add 0 when something is multiplied by 10
168
Availability Heuristics
Judge the probability of something based on what automcatically/most easily pops into your head
[what is available]
Ex. plane vs. roadway accident experiment by Kahneman and Tversky
K more common first letter vs 3
more likely to be third, but easier to think of first
169
Representativeness Heuristics
Judge the probability of something based on how well it matches a prototype or schema that we already have
Kahneman and Tversky again
Likes poetry- professor poetry fan or truck driver
Far greater amount of drivers than professors
170
Confirmation bias
Look for evidence that supports what you already believe
| Explain away contradictory
171
Belief Perseverance
Once we have formed a belief, we are slow to change minds even if direct evidence against it
especially once public
ex. prezzz---> vote and campaign but then he is super sleazy, less likely to change stance
172
Cognitive Dissonance
Thoughts or behaviors don't match
tension caused by conflicting ideas support for pres vs corruption
Ignore poor performance and convince ourselves that he is doing a good job to feel better
173
Self-Serving bias
take credit for success and blame circumstances for failures
Do well on a test---> such a good studier
Do poorly ----->bad teaching, exhaustion, temperature in the room, etc...
174
Overconfidence
people tend to want to be right and believe that they are 11
175
The Dunning-Kruger Effect/illusory superiority
People who are bad at something often think they are really good
Incompetence helps keep them from realizing incompetence
ex. oblivious drivers don't see how bad they are
ex. Worst comedians gave themselves higher scores
176
Hindsight bias
Knew it all along
when people learn an outcome/solution, seems obvious
convinced they knew it all along
After a failure, more knowledgeable about error than while game was occurring
