Presentation Transcript

  1. Research on development of adult intelligence • Cross-sectional studies: • Steady decline • Cohort effect? • Longitudinal studies: • Continued improvement through 50s • Problems? • Cross-sequential • Replace drop outs • Improves through 50s

  2. Reseach on development continued • Basic skills decline to age 25 at: • Verbal meaning: 74 • Inductive reasoning: 67 • Spatial orientation: 67 • Word fluency: 60 • Issue of “use it or lose it” recommendations

  3. Current approaches to measurement • Wechsler Adult Intelligence Scale (WAIS-III). Measures 4 domains: • Verbal • Nonverbal/spatial • Working memory • Processing speed

  4. Measurement continued • Stanford-Binet Test of Intelligence • Verbal • Quantitative (math) • Spatial reasoning • Short-term memory Distribution of scores x = 100, SD = 15 or 16

  5. Validity of IQ scores? • Predict school performance • Predict educational level • Predict occupational success • Only account for 25% of variance

  6. What affects intelligence test scores? • Biology • Environment • Remember nature/nurture interactions • culture

  7. Emotional intelligence • Ability to reason about emotions • Recognize the meaning of emotions • Use those emotions to facilitate thinking • Manage them

  8. Model of emotional intelligence • 4 branch model of EIQ: • Perceiving emotion • Using emotion to facilitate thought • Understanding emotions • Managing emotions Daniel Goleman’s book Emotional Intelligence (1995)
