Language Flashcards
Phoneme
Single unit sound that changes meaning
Variation of pronunciation of 1 phoneme
Not all languages = same phoneme
Morphemes
Smallest units of meaning
Combination of phoneme
Morphemes 2 types
Unbound - words - content
Bound - prefix/suffix - function
Semantic processing
Content words (concepts, categories)
Syntactic processing
Function words
Semantic examples
Nouns
Verbs
Adjectives
Syntactic examples
Pronouns
Prepositions
Conjunctives
Sementics
Cued by syntax
Maps -> Meaning
Syntax
Structure of language
Word order and class
Word order
Who is doing what to whom
Word class
Word order help identify word class = fits/make sense
Language area of brain

Lower edge frontal, upper edge temporal
Broca’s Area
Production of language
Near speech production
Wernicke’s Area
Translates sounds into meaning
Wernicke’s Area in brain
Left temporal lobe (next to primary auditory cortex)
Aphasia
Inability to produce/understand language
Aphasia Broca
Focus on content
Struggle to combine words
Effortful
Aphasia Wernicke
Void of content
Function morphemes
Fluent
Deep meaning 2 examples
2 surface, 1 deep (words different, meaning same)
1 surface, 2 deep (words same, meaning amiguous)
Language development newborn
Basic phoneme contrasts
Not restricted to language

Love = constant Habituation = decrease New = increase Old = same
Consonant sounds
Categorical by VOT
Voice onset time
Time interval b/w release of consonant and onset of voicing

Comprehension vs production
Comprehension precedes productive vocab by x2
Sudden increase 18 months/ first 50 words learned
Vocal burst
Symbolic nature
Control over articulation
Easier retrieval
Underextension
Only one specific meaning
Overextension
1 word = extended meaning
% decrease with more vocab
Communicate beyond single words
Protowords
Non-verbal function
Holophases
Single word = entire sentence
Early sentences
Sematic relations
Later syntactic development
Resemble adult language
3 theories of how children acquire language
Nativist views of language
General learning capacities
Social learning
Nativist views of language
Biologically predisposed to learn syntax of language
Rapid, effortless
Language biprogram hypothesis
Pidgins language
Creoles
Pidgins language
Invented language from many different languages
Creoles
Pidgin = native language
More grammatically complex
Sensitive period
Ideat time to acquire language
Ends with lateralization
Syntax error decrease with age
General learning capacities
Highly developed pattern recognition
Word boundaries
Pick up regularities with needed innate language categories
Social learning before
Parentese - simplified speech, exaggerated intonation (make connections)
vocab = amount of language from parents
Social learning
Words = things
Social rountines
Self - construal
Self - construal
Varies with culture
Interdependent

Representation
Knowledge of world to form content of our thoughts
Analogical representation
Mental images
Concept but with many similarities to actual external stimulus
Symbolic representation
Propositional thoughts
Express ideas
Categorisation of concepts (shows predicted behaviour)
Deductive reasoning
General tospecific
Logical problems - validity of conclusion
Inductive reasoning
Test hypotheses
Specifics infer to general principles
Belief bias
Reason on basis of plausibility rather than logical rules
Confirmation bias
Seek info/conformation vs to falsify hypotheses
Heuristics
Shortcuts correct majority of the time
Drawing conclusion from experiences
Availability heuristic
Probability estimate influences by how easy info is retrieved
More available = more frequent = more likely to happen
Saliency bias
Uses of images to connect with another topic usually negative way
More available vs facts/figures
Problem solving
Trial and error
Algorithm
Heuristic
Algorithm
Rule -> solution
Impricise, can’t guarantee same solution
Heuristic
Stagery that doesn’t always guarentee solution
Saves time
Means - end analysis
Sub - goals to final goal
Less demanding and evaluate after each goal
Hill climbing
Change current state of problem, closer to solving it
Creativity in problem solving
Divergent thinking
Change representation of problem
Analogy
Analogy
Using method from past to solve current problem
Structural/ context similiar
Obstacles to problem solving
Mental set
Functional fixedness
Mental set
Fixed mindset - hinders problem solving
Functional fixedness
Fixed usual function of objects
Overcoming obstacles
Mental rest
Practice divergent thinking
Whorfian Hypothesis
Having specific language determines or influences how we think
Affects view of world and limit thinking
Evidence for Whorfian Hypothesis
Colour processing
Space and time
Culture and thinking style
Focal colour
Most representative colour of colour category
Set of systemic terms for basic colours
Universal focal colour
Memory, without label
Difficult to separate from other colours
Against colour processing
Dani tribe
2 colour terms (light and dark)
Perception, memory similar to speeches with many colour terms
For colour processing
Russian Blues Experiment
English - all blues spectrum in 1 category
Russian - goluboy (light blue) & siniy (dark blue)
Russian Blues Experiment findings English
High accuracy, slower
No categorical advantage
Not affected by verbal interference
Russian Blues Experiment findings Russians
High accurary, faster
Affected by verbal interference - stop recruiting categories
Space and time
Language change thinking about space or time
Relationship b/w spatial motion and abstract concept of time
Ego - moving
Moving towards time
Time - moving
Time moving towards you
Temporal relations marked by spatial metaphors
Varies b/w languages

No change in environment
Limitations Abecedarian Project
Overestimate genetic components
Influence IQ through development
Overestimate genetic components why?
Gene x environment interaction
Gene invites certain environment influnces
Influence IQ through development why?
Schooling, trauma, teratogens (drugs assumed during pregnancy)
Race and intelligence
Mean difference of IQ b/w is changing
Environment influence development of particular cognitive abilities

African - American children high SES vs low SES why?
Bigger difference for high SES
Heritability estimates differ b/w SES groups
Stereotype on performance
Negative
General assumption
Minimize motivation
