Chapter 9: Intelligence and Its Measurement Flashcards
Intelligence
Multifaceted capacity that manifests itself in different ways across the lifespan
Abilities included in Intelligence
Acquire and apply knowledge Reason logically Plan effectively Infer Perceptively Make sound judgments and solve problems Grasp and Visualize Concepts Pay Attention Be Intuitive Find the right Words and Thoughts with Facility Cope with, adjust to, and make the most of new situations
Henry Goddard’s Definition of Intelligence
The degree of availability of one’s experiences for the solution of his present problems and anticipation of future ones
Strernberg’s Behaviors associated with Intelligence
Problem solving ability
Verbal ability
Social Competence
Sir Francis Galton
Remembered as the first person to pusblish on the heritability of intelligence, thus framing the contemporary nature-nurture debate; believed that logic, visual acuity or hearing ability are tests of intelligence; Viewed intelligence as a number of distinct processes or abilities that could be assessed only by separate tests
Alfred Binet
Components of intelligence: reasoning, judgment, memory, and abstraction; argued that when one solves a particular problem, the abilities used cannot be separated because they interact to produce the solution
David Wechsler
Acknowledged complexity of intelligence and its conceptualization as an aggregate or global capacity; added that there are nonintellective factors that must be taken into account; best way to measure global ability was by measuring aspects of several qualitatively differentiable abilities (verbal- or performance-based in nature);
WAIS III
Test Data According to: Verbal Comprehension, Working Memory, Perceptual Organization, and Processing Speed
Jean Piaget
Intelligence conceived as a kind of evolving biological adaptation to the outside world; process of cognitive development is thought to occur neither solely through maturation nor solely through learning; As a consequence of interaction with the environment, psychological structures become reorganized; unfolding of stages of cognitive development is the result of the interaction of biological factors and learning
Schema
Form of cognitive organization or reorganization in a mental structure; refers to an organized action or mental structure that, when applied to the world, leads to knowing or understanding
Schemata
Plural of schema
Piaget’s concept of learning
Through two basic mental operations: Assimilation and accomodation
Assimilation
Actively organizing new information so that it fits in what already is perceived and thought
Accommodation
Changing what is already perceived or thought so that it fits with new information
Interactionism
Thread running through the theories of Binet, Wechsler, and Piaget; reers to the complex concept by which heredity and environment are presumed to interact and influence the development of one’s intelligence
Factor-Analytic Theories
Focus is squarely on identifying the ability or groups of abilities deemed to constitute intelligence
Information-Processing Theories
Focus is on identifying the specific mental processes that constitute intelligence
Factor Analysis
Group of statistical techniques designed to determine the existence of underlying relationships between sets of variables, including test scores; used to study correlations between tests measuring varied abilities presumed to reflect the underlying attribute of intelligence
Charles Spearman
Pioneered new techniques to measure intercorrelations between tests; found that measures of intelligence tended to correlate to various degrees with each other; formalized observations into an influential theory of general intelligence that postulated by the existence of general intellectual ability factor that is partially tapped by all other mental abilities
Two-Factor Theory of Intelligence
g represents the portion of the variance that all intelligence tests have in common and the reamining portions of the variance being accounted for either by specific component (s), or by error components (e) of this general factors
High positive correlation with other tests - highly saturated with g
Low or moderate correlation with other tests - viewed as possible measures of specific factors
g
The higher the magnitude of g in a test of intelligence, the better the test was thought to predict overall intelligence
Group Factors
An intermediate class of factors common to a group of activities but not to all; neither as general as g nor as specific as s (linguistic, mechanical, and arithmetic abilities)
Gardner
Described interpersonal intelligence and intrapersonal intelligence as a part of emotional intelligence
Raymond B. Cattell
Developed types of cognitive abilities
