1.Theories of Intelligence
Piaget, Vygotsky, Sternberg, & Gardner
2.Theories of Intelligence
Geographic: IQ testing, Spearman
Computational: cog. neuroscience
Epistemological: child development, Piaget
Sociological: Vygotsky, Sternberg
Systems: Sternberg, Gardner
3.Frames of MindTheory of Multiple Intelligences
Sources of Theory:
Piaget
Vygotsky
Sternberg
4.Jean Piaget
1896 - 1980
5.Piaget: Child as Scientist
Discovers & creates knowledge of world
Discovers & creates methods of knowing the world
Stages of Development
Stable periods: equilibrium
Transitional / crisis periods: reorganization
6.Piaget: Basic Processes
Adaptation: agreement of thought with external world
Assimilation: adding new info to old schemas
Accommodation: adapting schemas to new info
Organization: internal coherence of knowledge
7.Equilibration and Reorganization
Confirmation of knowledge
equilibration & stability
Disconfirmation of knowledge
disequilibrium & reorganization
9.Sensorimotor Stage
Coordination of reflexes
Beginning of object permanence
Emergence of causality
Active experimenting on world
Invention of new means by mental combination (18 – 24 months)
beginning of symbolic thought
10.Symbolic / “pre-operational”
Use of symbols: language, numbers, etc.
Concrete: limited to here & now
failure to recognize conservation
Egocentric: focus on child’s relations to objects, not relationships of objects with other objects
11.Concrete Operations
Basic logical & mathematical operations
(including conservation of substance, volume, weight;
classification)
Can think in ways that contradict immediate impressions
Can’t manipulate systems of abstractions
(can’t do proofs of theorems)
12.Formal Operations
Operations on operations
(Given bucket of water & objects -- asked to figure out why some float and some don’t -- can figure out notion of density.)
Mental exploration of possible worlds
13.Piaget: Main Criticisms
Periods achieved gradually, with little discontinuity
Can perform some higher-level tasks when procedures modified
Operations often don’t generalize, but remain specific to tasks
14.Lev Vygotsky
1896 - 1934
15.Lev Vygotsky
Intelligence is social & cultural
Growth of intelligence based on internalization of social processes
Intelligence is product of history; resides in culture
16.Vygotsky: Key Ideas
Tools & symbols
Zone of Proximal Development
(ZPD)
Apprenticeship Learning
17.Robert
Sternberg
18.Robert Sternberg
Analytic: what IQ & achievement tests measure
Practical: real-world problem-solving
Creative: art, music, literature, etc.

(eliminates or spares)
Information-processing systems
Developmental history
Evolutionary history or plausibility

24.Intelligences
Linguistic
Logical-mathematical

Bodily – Kinesthetic
Personal: knowledge of self & others
