Human language
Symbols
= Arbitrary pairings between a person/thing and an idea that people agreed to correlate the two
Generativity
= Basically, humans can say things and others can understand those new ideas, imagining them, etc.
Parts of language
Phonemes
= The sounds of human language, the basic structure for everything in language
= The smallest units of sound recognizable as speech rather than random noise
EX: vowels in english, consonants in english
= Each of the world’s languages have a unique set of phonemes
= Not all language use all phonemes
Semantics
Words composed of one or more Morphemes
Morphemes
Smallest components of human language that also have meaning
= Needs one phoneme to make a morpheme
EX: the sound S
Syntax
Grammar for sentences
= The rules governing how words are combined to form meaningful phrases and sentences
= Syntactical rules differ across languages
English: I went to the beach yesterday
Spanish: Yesterday went to the beach
French: I am gone to the beach yesterday
Pragmatics
Context, tone, body language, how we say the sentence
Metalinguistics
= Using all these components to talk about language itself
Types of bilingualism
Simultaneous (early) bilingualism
Sequential bilingualism (many different home languages but one at school, in order from one to next)
Heritage bilingualism (main language is english but another language you sorta understand)
Adult second-language bilinguialism
Intelligence
Formal definitions
= The ability to learn or understand, or to deal with new or challenging situations
= The ability to apply knowledge to manipulate one’s environment
= The ability to think abstractly as measured by objective criteria
Other definition
= A set of abilities that increase an organism’s likelihood of survival and reproduction
Three-tiered model
How do we measure intelligence
IQ tests
IQ tests are created to produce a standard score in the age group and location in which they are presented
Mean score on IQ tests is designed to be 100
Standard deviation is designed to be 15
= Why is intelligence important
Many humans are not faced with frequent threats to our physical survival
So why does intelligence matter?
= It still helps us thrive in our environment
In humans, intelligence might predict
= Academic success
= Economic success
Occupational success
Success begets success and the rich get richer
= The effects of intelligence are self-perpetuating
Intelligence test examples
Intelligence tests are different for different ages
Ideational fluency for 7-year-olds
= When you see the word PLANT, what else do you think of?
Naming facility for 5 year olds
= What is happening in this picture
Where does intelligence come from
Genetics
= IQ scores are more similar between identical than fraternal twins
= IQ scores of adopted children are more similar to their biological parents’ than to their adoptive parents’ scores
Family environment
= IQ scores are positively correlated with protective factors (high parental involvement, stimulating physical environment, etc)
= IQ scores negatively correlated with risk factors (low SES, low maternal education, etc)
Education
= School enhances (builds on) children’s existing intelligence
= IQ scores are higher during the school year than the summer (for some children)
Gardner’s theory of multiple intelligences
Linguistic intelligence
Logical-math intelligence
Musical intelligence
Body-kinesthetic intelligence
Spatial intelligence
Inter-personal intelligence
Gardner’s theory of multiple intelligences
Evidence for Gardner’s approach
= These areas of intelligence have different developmental patterns (emerge at different ages)
= Damage to a specific brain area may impact only one type of intelligence and not others
Affect heuristic
A rule of thumb in which we choose between alternatives based on emotional or “gut” reactions to stimuli
Heuristics
A shortcut to problem solving, also known as rule of thumb
Representativeness heuristic
Recognition heuristic
A rule of thumb in which a higher value is placed on the more easily recognized alternative
Psychometrics
Availability heuristic
Analogical representations
Aphasia
Crystallized intelligence
