Thursday, October 22 • Objective: Compare and contrast learning theories Thinking Cognitive Abilities • All the mental activities associated with thinking, knowing and remembering Thinking: Concepts Concept • Mental grouping based on shared similarity • Categorizing items in one’s environment Prototype • Typical best example incorporating the major features of a concept • The closer a new object is to our concept prototype the easier it is to categorize it Concept Hierarchy • A means to keep mental information organized from basic concepts to specific ones Concept Hierarchy Thinking: Problem Solving Algorithms • Problem-solving strategy that guarantees the solution to the problem • Not always the most efficient method Heuristics • A rule-of-thumb problem solving strategy that makes a solution more likely and efficient but does not guarantee a solution • These can be handy shortcuts, or they can get us into trouble • Ex: “i before e, except after c” Insight • Sudden realization of the solution to a problem • “Aha” experience Thinking: Problems Solving Problems Mental Set • Tendency to approach a problem in a particular way • The set may or may not be helpful in solving a new problem Fixation • Mental set that hinders the solution of a problem • One needs to think beyond the mental set to solve the new problem Functional Fixedness • Tendency to think of things only in terms of their usual functions Functional Fixedness Can you think of a way to use these materials to mount the candle on a bulletin board? Functional Fixedness Confirmation Bias • Tendency to focus on information that supports preconceptions Availability Heuristic • Estimating the likelihood of events based on their availability in memory • Can be correct or incorrect • Activity: Availability Heuristic Overconfidence • When confidence is greater than accuracy Framing • How an issue is worded or presented • Can influence decisions and judgments Friday, October 23 • Objective: Define intelligence and methods of measuring intelligence Intelligence and Intelligence Testing The Nature of Intelligence Intelligence • Ability to learn from experience, solve problems, and use knowledge to adapt to a new situation • Is intelligence one thing or are there multiple intelligences? The Nature of Intelligence: Howard Gardner Howard Gardner (1943- ) • Author of a contemporary theory of multiple intelligences consisting of eight separate kinds of intelligence Gardner’s Types of Intelligence Gardner’s Types of Intelligence Gardner’s Types of Intelligence Gardner’s Types of Intelligence Gardner’s Types of Intelligence Gardner’s Types of Intelligence Gardner’s Types of Intelligence Gardner’s Types of Intelligence Charles Spearman (1863-1945) • Theorized that a general intelligence factor (g) underlies other, more specific aspects of intelligence General Intelligence (g) • Factor that Spearman believed underlies specific mental abilities The Nature of Intelligence: Emotional Intelligence Emotional Intelligence • Ability to perceive, express, understand, and regulate emotions • People high in emotional intelligence are more in touch with their feelings and the feelings of others. Intelligence Testing Wednesday, October 28th Intelligence Testing: Alfred Binet Alfred Binet (1857-1911) • Developer of the first test to classify children’s abilities using the concept of mental age • Assumed children’s intellectual abilities grew every year Mental Age • Chronological age that corresponds to the difficulty of the questions a child can answer • An average 8-year-old child should have the mental age of 8 years. Chronological Age • The actual age of a person Intelligence Quotient (IQ) • Number that results from dividing mental age by chronological age and multiplying by 100 • IQ = (MA/CA) X 100 • A score of 100 would be considered average • Formula has been replaced with modern versions Intelligence Testing: David Wechsler David Wechsler (1896-1981) • Developed the Wechsler intelligence scales which included: – Different tests for different age groups – Separate verbal and nonverbal scores – Subtests and subtest scores Wechsler Adult Intelligence Test Test Construction: Achievement and Aptitude Tests Achievement Tests • Tests that attempt to measure what the test-taker has accomplished • i.e. classroom tests at the end of a unit Aptitude Tests • Tests that attempt to predict the testtaker’s future performance • Examples: ACT and SAT Test Construction: Reliability and Validity Test Reliability • Extent to which a test yields consistent results Test Validity • Extent to which a test measures or predicts what it is suppose to • Does an achievement test accurately measure accomplishments? • Does an aptitude test accurately measure the person’s future performance? • One needs to know the purpose of the test
