Psychology 100 Chapter 8 Part III Thinking&Intelligence

Outline o Intelligence oIQ testing oInformation processing oMultiple intelligences Study Question: Compare and contrast crystallized and fluid intelligence. Give examples of each.

Alfred Binet Intelligence Alfred Binet ( ) –Role of environment –Higher-order abilities –Focus on children –Binet/ simon test Stanford-Binet scale: Mental age revision –IQ (intelligence Quotient) = (Mental/Chronological)X100 e.g, 15/12 X 100 = 125 Weschler Adult Intelligence Scale-Rev. (WAIS- R) –Verbal and Performance components

Francis Galton ( ) –Role of heredity >Speed of processing >Correlational statistics Charles Spearman ( ) –Intelligence: solo entity or many abilities? –Invented factor analysis to look at multiple correlation Example: Six tests 1.Vocabulary 2.Picture completion 3.Reading comprehension 4.Object assembly (puzzle) 5.General information 6.Block design IntelligenceDecisions Intelligence Francis Galton Charles Spearman

Test 1 Test 3Test 5Test 2Test 4Test 6 Fluid Crystal Raymond Cattell Intelligence Raymond Cattell ( ) –Discovered two underlying g’s >Fluid Intelligence  Raw ability to manipulate information >Crystallized Intelligence  Ability acquired through experience

Intelligence Information processing theory –Examine the stages/ components of information processing >E.g., STM, uptake of information, attention, retrieval from LTM >Linking with psychometrics: Elementary cognitive correlates  Lexical decision latency (retrieval from LTM)  Choice reaction time (judgment, directing movement)  Intelligence and speed of processing: Galton, revisited

Intelligence Information processing theory –Sternberg’s theory >Three components 1) Analytic intelligence. Mental mechanisms people use to plan and execute tasks. Metacomponents (‘g’) Lower components 1) Knowledge acquisition (learning) 2) Performance components (I-P stages)

Intelligence Information processing theory –Sternberg’s theory >Three components 2) Creative intelligence. Ability to deal effectively with novel situations and to automatically solves problems encountered previously. (fluid intelligence) 3) Practical intelligence. abilities acquired through our evolutionary history. (Crystalized intelligence) Adaptation: Developing skills to help fit into one’s environment Selection: Finding a niche in which to flourish. Shaping: Changing the environment.

Intelligence Neuropsychological Approach –Gardner’s Multiple Intelligences >Mono Savants -> Cognitively delayed with one specialized ability >Prodigies -> Normal with one specialized ability >Seven types 1.Linguistic. 2.Logical/mathematical. 3.Spatial. 4.Musical. 5.Bodily-kinesthetic. 6.Interpersonal. 7.Intrapersonal.

Intelligence Nature and Nurture –Galton & Binet, revisited –Nature >Twin studies  MZ reared together.86  MZ reared apart.72  Same sex DZ.62  Diff sex DZ.57  Siblings (together).41  Adopted.25  Parent - adopted child.16 –Nurture >Selective Breeding studies

Review Quiz 1 –Chapter 5 –Sudy questions >What are four common elements of our various senses? Use examples from two senses to clarify your answer. >Label diagrams of the following structures: The Ear, The Eye, The Tongue, Haptic Nerves, etc. >Compare and contrast the trichromatic theory of colour vision with the opponent process theory of colour. Relate these theories to the Law of Complimentary and the Three Primaries Law. >Describe the basic gestalt principles of grouping. >Why might a proponent of Kahneman’s attention theory feel that driving a car while talking on a cell phone is a bad idea?
