Ceci’s Bioecological Theory of Intelligence
1
History: Measure and Mismeasure
2
Issues to consider:
• Binet & eugenics movement
• Army Alpha & immigration laws
• Sir Cyril Burt & heritability in twins
• Hunt and Head Start
• Jensen & compensatory education
• Herrnstein & Murray: affirmative action
Social Policy applications are inevitable!
• How is the study of intelligence related to
public policy?
• Is intelligence a single factor? Or multiple
factors?
• How modifiable is intelligence? See chapter
14
• Which theory do you find most useful in
describing, explaining, predicting intelligent
behavior?
see Kamin, Gould
– Binet? Guilford? Sternberg? Gardner? Ceci?

Psychometric Approach
• Factor analysis (Guilford; Thurstone) vs
Spearman’s g
• Cattell’s fluid vs crystallized abilities
• positive manifold
1. Discuss the psychometric
approach to intelligence.
Include a discussion of
various psychometric
approaches and how these
views differ.
– high correlations among ECT’s
– Higher among low -IQ persons! (Detterman &
Daniel)
– Minimum level of domain-general g required
for individual abilities to operate?
• IQ tests: Wechsler, Stanford-Binet, Bayley

Sternberg’s Triarchic
Intelligence
• Contextual subtheory
– Cultural relativism
2. Compare and contrast
Sternberg’s triarchic theory of
intelligence and Gardner’s
theory of multiple
intelligences.
• Experiential subtheory
– Ability to deal with novelty
– Automatization
• Componential subtheory
– Metacomponents (monitoring)
– Performance components (encoding, retrieval)
– Knowledge Acquisition (attending, etc.)

Gardner’s Theory of Multiple
Intelligences
Seven Frames of Mind:
• linguistic, logical-mathematical, musical, spatial, bodily kinesthetic, interpersonal, intrapersonal
Criteria:
•
•
•
•
Potential isolation by brain damage
Existence of savants & prodigies
Identifiable core operation / set of operations
Distinct developmental history;
definable set of expert end-state performances
• Evolutionary history & plausibility
• Support from psychometric findings
• Susceptibility to encoding in a system

3. Discuss the importance of
context to intelligence. How
important is context in the
psychometric, Piagetian, and
information processing
theories? How important is
context in the theories of
Sternberg, Gardner, & Ceci?
9
Information Processing
Approaches
10
Piagetian Approach
Strategies (Campione)
Knowledge Base (Schneider)
• Experts vs Novices
• Differences in rate of development
(Keating)
• Discrepant findings: Keating vs Kuhn
– Chunk information differently
– Attend to different features
Speed of Information Processing (Kail)
• Similar RT’s across variety of tasks
• Efficiency of retrieval from LT memory
Metacognition (Borkowski; Pressley)

Ceci’s Bioecological Theory of
Intelligence
Can a test of intelligence be
culture-free? Culture-fair?
• Knowledge
• Motivation to try hard
• Communication skills
• Rapport with adult
• Familiarity with testing situation
Are schools culture free? Culture fair?
• Intelligence is multifaceted set of abilities
• Significance of context in determining
intellectual functioning
– physical, social, mental, & historical
• Domain specificity exists
• Performance influenced by motivation,
expectations, and background knowledge
