Psych1000 StudyGuide WUCK Language 3 Intelligence 9 Motivation & Emotion 20 Development 31 Social thinking & Perception 39 This guide contains notes on “Psychology: Frontiers and Applications” Fourth Canadian Ed. by Passer, Smith, Atkinson, Mitchell and Muir. This guide is intended for supplementary purposes only. Reading this is no substitute for going to class and reading the book. We hope we can help you as much as possible, but your grades are your responsibility. LANGUAGE CHAPTER 9 Language - system of symbols and rules to generate infinite possible meanings Psycholinguistics - study of psychological aspects of language COMPONENTS OF LANGUAGE Noam Chomsky’s Transformation Grammar Grammar Rules of how symbols can be combined Syntax Rules that govern order of words Semanticity Conveys meaning Surface structure Deep structure Generatively Finite symbols can be combined to an infinite Symbols and the Underlying meaning, number of messages their order semantics Displacement Allows us to communicate things that aren’t physically present (imaginary, past, future) Phoneme Morpheme Words Phrases Sentences Discourse No meaning on Smallest unit of Almost anything in Sentences their own. About meaning. Letter “s” english can be said combined into pronunciation. conveys pluralness with a vocabulary paragraphs, so it is a morpheme. of 850 words. articles, books, Ex. Letter L or D conversations. Ex. Dog, pre-, “s” PSYCH WITH MIKE Q. How many morphemes in “crosswords”? Humor •Phonological ambiguity - confusion of Two. (←Tilt screen to see answer) sounds (Knock knock jokes) •Lexical ambiguity - double meaning (a Explanation: “Crossword” is one and “s” is baker kneads the dough) another. “Cross” and “word” aren’t conveying •Syntactic ambiguity - confusion in separate meaning so they are one morpheme. “S” conveys separate meaning than the rest of the structure (man eating salmon vs man- word, pluralness, so it is also its own morpheme. eating salmon) •Semantic ambiguity - meaning (Call me a cab. Okay you’re a cab.) Bottom up processing: patterns ➡ syllables ➡ meaning Top down processing : interpreting things based on expectations THE BRAIN (Reading “The Bead Store” as “The Bread Store”) Broca's Area Speech Wernicke's Area Comprehension Speech segmentation - how do we know when words end? • We learn certain sequences are more likely to be at the end of words •Women have language in both hemispheres, • Context also makes it easier to tell when words end men have it in the left •If you acquire a language earlier in life, both languages use the same neural network •If you learn a language later in life, it gets its Pragmatics - knowledge of the practical aspects of using language own neural network and you use a different • Using language requires more than vocabulary and grammar • You must know not only what people are saying but what they mean part of the brain when you use that language •Even if you learn early and fluently, the and want you to do (Social context) inferior frontal gyrus goes off when you use a second language, indicating it requires more effort LANGUAGE LEARNING Motherese • High pitch, slow rate, •Infants vocalize (cry, babble) from the first moments of life - even deaf infants exaggerated tone mothers use •Show phoneme discrimination by 2 months (PA vs BA) when talking to babies •Babies are equally sensitive to phonemes from foreign languages - we’re hard • Adults shift “automatically” wired to acquire languages • Infants prefer this speech to •At 6-12 months, they can only discriminate between sounds in their native tongue normal adult speech •Language Acquisition Device (LAD) - humans are born with an innate biological • Learning about pausing, pitch, mechanism that contains general grammar rules (nouns, verbs) characteristics of speech •A huge electrical “switchboard” that is calibrated to your language •Is language learned as a result of imitation and reinforcement (Skinner’s idea)?

PSYCH WITH MIKE Critical Periods Will language develop on its own? • The white crowned sparrow must be A. “Feral children” (Amala and Kamala) did not learn language on exposed to an adult song between day their own. 7 and 60 or it will never be able to sing B. Isolated children might learn language depending on how early • Humans must be exposed to language they are introduced to it. 6yo is fine, 14yo is too late. C. Children with no models may be able to learn language. Ex. Deaf between 3 months to around puberty children with hearing parents who don’t sign. (early teens) or they will not be able to D. Can other animals learn language? No. Languages have been learn to speak taught to chimps but they have no real syntax or propositional thought. Second language critical periods: You definitely learn the language better if you learn it earlier, but a biological critical period is debated. Linguistic Influences on Thinking • Linguistic relativity hypothesis - language determines what we are capable of thinking • For example: would a culture with fewer words for colors actually be less able to tell colors apart? Studies testing this are inconsistent. THINKING • Language doesn’t determine what you think, it influences it • Chinese language uses ten-one, ten-two instead of eleven and twelve so Thought and language are closely related. children learn math easier in Asian countries Telling people to talk out loud can be used to study thinking patterns (calledirected thinking ).

Intelligence is a socially constructed concept. People that live in farming communities in different countries don’t solve logical problems the same way as others but it doesn’t mean they’re less intelligent. SIR FRANCIS GALTON ALFRED BINET •Believed thatintelligence was inherited •French government asked him to find out and that smart people were “more fit” for why certain kids didn’t learn in school as well thinking than dumb people •Believed that intelligence was a “collection • Measured reaction speed, hand strength, and of higher-order abilities” meaning there sensory acuity to test intelligence would be no correlation between each of the • Believed intelligence wasunitary (based on abilities that make up intelligence mental quickness) Assumed that a) mental abilities develop with • • Thought skull size was related to intelligence age and b) rate of development is constant • Turned out to be totallywrong about •Developed a standardized test measuring intelligence but he did create interest in the memory, math, vocabulary etc. field. •Also correlated his test with the teachers’ • He also developed the correlation ratings of the children to make sure the results coefficient so he wasn’t totally useless were meaningful (criterion validity) •Developed a testing score called “mental age” BINET’S LEGACY WILLIAM STERN A prof at Stanford developed an IQ test for •Built on Binet’s idea of mental age and american culture.

(Can’t just test addition if you’re testing math) • Test-retest reliability- are scores stable over time? •Criterion-related validity - Do scores on the test predict • Internal consistency - do all items seem to be some present or future behavior related to what its measuring the same thing? Interjudge reliability- do different raters/scorers supposed to measure? (Like what Binet did with the • teacher’s ratings) agree on their scoring? Culture Fairness Standardization Is the teculture-fair or doesit require knowledge only The development of norms - test scores from a large available to specific culture.e. asking an urban community sample that represent particular age segments of the farming related IQ questions. population •Chitterling test is bias to ople in Southern US states THE NATURE OF INTELLIGENCE Psychometric Approach SPEARMAN • Psychometrics - statistical study of psychological tests •Modern Galton - believed intelligence is a based • What are the mental abilities of the human mind? on one general skill • Is intelligence a general mental capacity, or several •Called this general skill theg-factor specific mental abilities? •The g-factor is what most people call “intelligence” today • Uses factor analysis to see if there are clusters of •G-factor predicts job success even better than measures abilities that are correlated with each other (ex. if reading, of specific ability tailored to specific jobs writing and speaking are correlated maybe there is an underlying skill that makes you good at all of them) Thurstone' 7 CATTELL & HORN THURSTONE • Spacial ability Modern Binet - believed intelligence is more • Verbal • Believed there are two subtypes of the g-factor: • comprehension crystalized and fluid intelligence complex than just a g-factor • Word fluency • Number facility • Crystallized intelligence (g ) c - ability to apply •Believed there are 7 independent primary • Perceptual speed previous knowledge to current problems mental abilities • Rote memory Believed not all tests are necessarily • Reasoning •Vocab, info tests • •Based on long term memory correlated because they are measuring • Fluid intelligence (g )f - ability to solve new problems different primary mental abilities Reasoning, creative problem solving •These types of measures are much more • •Towers of hanoi, 9 dot problem useful for education, because you can help children succeed in specific subjects •Based on working • We use more fluid intelligence when we’re children, and more crystallized when we’re adults CARROLL The Three Stratum Model Cognitive Approach • Attempt to explain why people vary in mental skill • Stratum III - General intelligence (g) • Stratum II - Eight broad intellectual factors, in • Explore specific info-processing that underlies intellect order of their correlation with g Fluid, Crystalized, Memory/learning, Visual, • STERNBERG Auditory, Cognitive speediness, Processing speed Triarchic theory of intelligence • Stratum I - 70 highly specific cognitive abilities •These correlate on average 0.3 with one another, •Metacomponents - higher order processes used to plan and regulate task performance (Smart people spend more indicating the influence of g time framing problems and developing strategies) •Performance components - actual mental processes used to perform task (Perception, memory, schema retrieval) •Knowledge-acquisition components - learn from experience, story info in memory, combine new insights with old info Beyond Mental Competencies Sternberg’s Classes Of Intelligence •Analytical intelligence - academic style problem solving •Practical intelligence - skills to cope with everyday GARDNER demands, manage oneself and others Gardner’s Multiple Intelligences •Creative intelligence - skills needed to deal adaptively with novel problems •Intelligence is made up of independent intelligences that relate to different adaptive demands •These classes also have an underlying g-factor but sometimes they are completely distinct •Linguistic intelligence - the ability to use language well •Logical-mathematic intelligence - ability to reason mathematically and logically •Visuospatial intelligence - the ability to solve spatial problems •Musical intelligence - the ability to perceive pitch and rhythm Emotional Intelligence •Bodily-kinesthetic intelligence - the ability to control body • Perceiving emotions movements and skillfully manipulate objects • Using emotions to facilitate thought •Interpersonal intelligence - the ability to understand and • Understanding emotions relate well to others • Managing emotions •Intrapersonal intelligence - the ability to understand oneself • Measured by the Mayer-Salovey-Caruso Emotional Intelligence Test •Naturalistic intelligence - the ability to detect and understand phenomena in the natural world •Existential intelligence - oriented ability to ponder questions Proponents suggest that emotionally intelligent people about the meaning of one's existence, life, death • Form stronger emotional bonds with others • Enjoy greater success in careers, marriage, and childrearing The first three are measured by existing tests, the others are • Modulate their own emotions to avoid depression, anger, anxiety • Work more effectively toward long-term goals not. Einstein, Tiger Woods and a street-smart gang leader all exhibit adaptive forms of intelligence says Gardner. • More effective coping strategies PSYCH WITH MIKE In class, Mike gave the example of a sea serpent underwater to explain the multifaceted nature of intelligence. You can only see some parts above the water so you can’t properly tell if its one serpent? or two? four? Aptitude vs Achievement Achievement testing Aptitude testing • Pro: is usually a good predictor of future • Pro: It is fairer performance in a similar situation • Con: It is difficult to construct • Con: it assumes that everyone has had the same a test that is independent of opportunity to learn the material being tested prior learning Static vs Dynamic Testing Static testing Dynamic testing • Dynamic test scores correlate more highly with education outcomes Completely standardizing test Standard testing followed up by the • Very useful when testing people environment so everyone is examiner giving the subject without equal educational responding to the same feedback, and then measuring their opportunities, and people not stimulus and all that is being ability to improve and respond to accustomed to Western-style testing tested is their ability feedback The Flynn Effect Intelligence in Other Cultures • The world’s population is progressively • Sternberg’s Theory Of Successful Intelligence: scoringhigher and higher on intelligence is what is required to meet adaptive intelligence tests demands of the culture • The nature of IQ allows its meaning to be • Raven’s Progressive Matrices - non-verbal preserved even when this happens because the task where one must decipher rules of the mean is always calibrated to be 100 - IQ is a relative pattern and pick the next figure measure • Good example of a non culture-specific • IQ’s increase 3 points per decade in the west measure of intelligence • Why?
