Unformatted text preview: Intelligence Definition • Intelligence: – Combines verbal ability – Problem solving – Ability to adapt & learn from life’s everyday experiences • Intelligence: historically defined by how we “measure” it • Alfred Binet: – Developed intelligence tests to identify slow learners – “Mental” Age: • Based on ability NOT chronological age – Ex. You can be 8 years old, and have a mental age of 12 – really smart in answering these questions • However, this formula for IQ was flawed. – A child with a mental age of 6 and chronological age of 5 would have the SAME IQ as a child with a mental age of 12 and chronological age of 10 – Not using quotient formulas anymore • Newer tests were developed with norms for all age groups based on a standard distribution (bell-shaped curve) • Stanford-Binet & Wechsler Intelligence Tests are still used today Weschler IQ Tests • Wechsler Intelligence Tests: – WPPSI: (preschool) – WISC: (children) – WAIS: (adults) • Results in a Verbal IQ, Performance IQ and Full Scale IQ score (100 is mean IQ – set that way) • Based on norms for the population: – 100 is the mean; normal range: 85-115 Flynn Effect • The Flynn Effect: – James Flynn found that from one generation to the next, there have been steady gains in IQ scores across culturally Why? • Hypotheses: – More time in school , better educated parents , better nutrition , broader exposure through media • Wechsler Adult Intelligence Scale most recently revised in 2008 • Wechsler’s view of intelligence : – “The global capacity of a person to act purposefully , to think rationally and to deal effectively with his/her environment” • Test Revisions for the WAIS-IV (2008) identifies several scale scores • Verbal Comprehension Scale • Perceptual Reasoning Scale • Working Memory Scale • Processing Speed Scale (& effectiveness) Sample of Verbal Subtests – Vocabulary: • Breadth of concepts, ideas and experiences; + correlated with overall IQ – Information: • Basic fund of information; culturally sensitive – Comprehension: • Awareness of socially appropriate behavior, rules and roles – Similarities: • Verbal concept formation, level of abstraction – Arithmetic: *********** It’s a verbal subtest! • Concentration/attention; mathematical ability – Digit Span: • Attention & rote memory (learning by repetition, memorizing) Sample of Performance Subtests – Picture Completion: • Visual organization and concentration – Block Design: • Perception & analysis of patterns – Digit Symbol: • Imitative behavior & learning capacity (Ex. given image, and “copy” what it’s associated with – when see 3, draw circle) – *Visual Puzzles • Perceptual reasoning – *Cancellation • Processing speed – *Figure Weights • Perceptual reasoning Rosenthal and Jacobson Study...
