• INTELLIGENCE– history of testing and intelligence tests– how to make a proper test (valid, reliable, standardized)– verbal vs. performance subtests– Spearman

• logic of factor analysis• one main factor (g) + specific factors (s’s)• what is g?

– faster processing?– better executive function?– working memory, perhaps in lateral prefrontal cortex

– Cattell• two main factors• fluid intelligence• crystallized intelligence

– validity of IQ tests• some predictive use, but not great

Three Minute Review

• Other types of intelligence– savants– Gardner -- multiple intelligences– Goleman -- emotional intelligence

• Heredity of intelligence– strong genetic component– some environmental component– Flynn effect

• IQ has increased over time• genes haven’t changed that quickly -- what has?

– both genes and environment are necessary

Test Yourself• Rashi is given several intelligence tests and is found

to do well above average on most areas, including mathematical, verbal, and spatial abilities. Spearman would attribute Rashi's high performance across this variety of tests to:

a) g (general intelligence). b) s (specific ability).c) fluid intelligence. d) crystallized intelligence.e) mental age.

• hard to identify word transitions in speech• speech recognition systems require slow, paused

speech• misunderstandings

– mondegreens– “It’s a doggy-dog world”– “Our father wishart in heaven; Harold be thy name”– Jimi Hendrix

• “’scuse me while I kiss this guy”– Red Hot Chili Peppers

• “Wait for the shed; it’s a lonely view”?

Assembling MeaningSounds à phonemes à morphemes à words à sentences àmeaning

Grammar• the rules of language

– phonology -- assembling sounds– morphology -- combining word parts

• “The boy hit the ball” vs. “The boy hitted the ball”

– syntax -- word order• “The boy hit the ball” vs. “The ball hit the boy”

• Semantics– meaning

• “The boy hit the ball” vs. “The boy went to the ball”

• Deep Meaning– the underlying ideas based on context and culture

• She: “I am leaving you.”• He: “Who is he?”

Ambiguous Phrasing

When things go wrong• Translation errors based on alternative word

meanings– In a Bangkok dry cleaner's

• "Drop your trousers here for best results."– Outside a Paris dress shop

• "Dresses for street walking."– In an Acapulco hotel

• "The manager has personally passed all the water served here."

• Headlines with noun/verb ambiguity– British Left Waffles on Falklands– Stud Tires Out– Chou Remains Cremated– Teacher Strikes Idle Kids– Squad Helps Dog Bite Victim– Hershey Bars Protest– Deer Kill 130,000

• Translation software– “The vodka is good but the meat is rotten.”

Mentalese• Is language the basis of thought?

• Do words that exist in other languages allow new concepts?– “Schadenfreude” (German, damage + joy) = experiencing pleasure at

someone else’s misfortune

• Do our words bias our thoughts?– stewardess vs. flight attendant– fire man vs. fire fighter– chairman vs. chair or chairperson

• Do “Eskimos” (Inuit) really have so many (e.g., 300) words for snow?

Linguistic Relativity (Sapir & Whorf)• Whorf’s problem with “empty” oil containers• culture, through language affects the way we think• “another language, another soul”

Language in the Brain

Broca’s aphasia• follows damage to left frontal lobe• problems generating speech• not a problem moving mouth muscles• often accompanied by right hemiparesis

– why?

Paul Broca

The brain of Broca’s patient “Tan”

Broca’s Area

Wernicke’s aphasia– occurs with left hemisphere damage– problems with language comprehension– fluent nonsense

visual cortex

auditory cortex

Wernicke’s area

(language comprehension)

Broca’s area

(language generation)

motor cortex

(mouth, lips tongue)

Thin Slices of Behavior• subjects watched soundless

video clips of teaching assistant for 2, 5 or 10 seconds

• students rated how accepting, empathic, optimistic, professional, or supportive the teacher seemed

• correlation with teaching ratings of students in the instructor’s class: .76

Physical Space• depends on how

well you know the other person

• depends on situation (e.g., elevator, subway)

• larger for pairs with status difference than for peers

• distance is set by higher status person

• smaller for women than men

Physical Space

• need more space face-to-face than back-to-back

• how to freak people out in an elevator (or at a urinal)

Facial Expressions

• In this picture, an experienced flight attendant demonstrates a facial expression she uses at work. Is she performing genuine warmth, or is it concealed irritation?

a. Genuine Warmthb. Concealed Irritation

Fake vs. “zygomatic” smiles

Eye Contact• indicates attentiveness, credibility• conveys intensity of feelings

– couples in love• makes people more likeable

– higher tips• when does a gaze become a stare?

– aggressive, causes discomfort• culturally specific

– Asians < Americans < Arabs • higher status individuals make more eye

contact, lower status individuals look away more

Body Language• twitching = nervousness• open posture (e.g., arms open)• closed posture (e.g., arms crossed)• leaning toward you = positive attitude• leaning back = negative attitude or

defensiveness• higher status person

– more open posture

Who just won the basketball game?

Gesturing while on the phone

Why do you gesture when no one is watching?

Interactional Synchrony:

congruent posture, congruent minds
