CLASS 13 Approach 3: Beyond ‘g’ Spearman says g underlies all intelligence But we all know someone who….. Most people think and some researchers agree that: Intelligence is more than ‘g’ Statistical Paradox ? Everyone believes that some people are more intelligent than others But everyone believes that they are above average Statisticians say impossible ! Psychologists say no paradox Dunning solves the paradox: Our personal definitions ensure that we are above average What other definitions have a legitimate basis? Gardner’s multiple intelligences TRADITIONAL Logical-mathematical Spatial (geometric) Linguistic (verbal) Inter-personal (social) CONTROVERSIAL Intra-personal Musical Kinesthetic Naturalist Spiritual Gardner’s latest Replaced Spiritual intelligence with: Existential intelligence Moral intelligence Here are some recent nominees: Which type of intelligence does each have? Albert Einstein Logicalmathematical intelligence Oprah Winfrey Interpersonal intelligence Gary Kasparov Spatial intelligence Eminem Linguistic intelligence Sigmund Freud Intra-personal Intelligence Patrick Kane Kinesthetic intelligence Mahatma Ghandi Spiritual intelligence David Suzuki Naturalist intelligence But where is creativity? Suggestions for other intelligences? Critique of Gardner’s approach Much subjective opinion Many of the intelligences are too vague to be measured objectively Without measures, no practical value yet IN HIS DEFENSE: used multiple sources CYNICAL VIEW: everyone needs to feel intelligent and Gardner just wants to make us all happy Empirical components Spearman (1 = g) Wechsler (2) Cattell (2) Thurstone (7) Guilford (120) Scholastic aptitude Scholastic Aptitude Test (SAT) – 3 subscales (math, reading, writing) Graduate Record Exam (GRE) -- 3 LSAT, MCAT, GMAT (2-3 subscales) Sex differences? Have diminished over time Some remain – even on GREs Writing ability favors females (recent addition) Spatial rotation favors males Why sex differences? Nature: Brain differences ? Nurture: sex roles ? e.g. spatial ability Sex differences in g No sex differences on Stanford-Binet Coincidence ? Summary Several empirical components are reliably distinguished Many conceptual intelligences not yet measured Traditional sex differences are diminishing but some still evident Emotional Intelligence Being good at perceiving, understanding, and expressing emotions More important than IQ? But how to measure? One approach is to test ability to judge emotions accurately. Q: What emotion? A: Sadness, as judged by the person who made the drawing Q: what emotion? A: grief: -as judged by consensus based on context A: Surprise -- based on instructions to pose. Q: What emotion? A: the joy of using Play Station 3, as judged by the manufacturer. Critique of EQ Difficult to evaluate emotion accuracy Self-reports are dubious Is emotional intelligence something else?
