Q

Spearman’s Two-Factor

Theory of Intelligence

A
 General Intelligence
(g): broad thinking
ability; “mental power”
that underlies all
intellectual tasks;
neurologically based
 Specific Intelligence
(s): abilities in
particular areas
(verbal, nonverbal,
etc); learned/honed

Q

Sternberg’s Triarchic Theory

A

Three interrelated subtheories used to explain how mental processes,
situations, and experience relate to intelligence
• Componential: analytical intelligence
• Experiential: creative intelligence
• Contextual: practical intelligence

Q

Gardner’s Theory of Multiple Intelligences

A

• “an intelligence is a biopsychological potential to process information that can be
activated in a cultural setting to solve problems or create products that are of
value in culture.”
• Contends that there is no “g” factor
• Overall level of functioning is determined by interaction of strengths and weaknesses
(intelligences) with cultural setting
• 7-9 intelligences, which may or may not be fully realized based on environmental influences

Creativity

A

• Original thinking and problem-solving that produces a product valued by
society
• Ability to do things in new or different ways

Q

Divergent thinking

A
  • Higher scores on word fluency and reading tests
  • Associated with Extroversion and Openness (5 Factor Model)
  • Loose memory networks
  • Right brain (especially temporal lobe)
  • Alcohol, humor, and sleep all increase creativity
  • Greater WMC decreases creativity

Q

Nature or nurture: The scientific data

A

• Higher order thinking- structural & functional neural networks:
frontal, parietal, temp lobes and cerebellum
• Correlations:
• Brain size
• Processing speed
• Brain efficiency hypothesis (related to glucose metabolism rates)
• Heritability: .75 (strong)
• Enriched environments produce changes in IQ
• Most notable in impoverished environments
• Average IQ is increasing over time
• Evidence of critical periods of development dependent upon stimulation

Q

Assessment of Intelligence

A
  • Intelligence Quotient (IQ)
  • Originally (mental age /chronological age) x 100; average IQ is 100
  • Intelligence tests:
  • Binet-Simon scale (1905)
  • Stanford-Binet Intelligence Scale 1916-)
  • Now in 5th Edition
  • The Wechsler Scales

Q

The Wechsler Scales

A
  • 15 subtests (10 basic, 5 optional)
  • Time of Administration: 90-120 min
  • 5 Index Scores
  • FSIQ= Full Scale Intelligence Quotient
  • Average of Four Indices:
  • Verbal Comprehension
  • Perceptual Reasoning
  • Working Memory
  • Processing Speed
17
Q

Verbal Comprehension

A

capacity to reason using learned information

and verbal expression

18
Q

Perceptual Reasoning

A

capacity to reason using visual stimuli

19
Q

Working Memory

A

capacity to retain information and work with

it/manipulate it in real time

20
Q

Processing Speed

A

capacity to complete simple tasks with speed and

accuracy

21
Q

Problematic Issues in IQ Assessment

A

• Controversy related to underlying nature/definition of intelligence
• Difficulty measuring/testing theories of intelligence of abstract skills
(e.g., Gardner)
• Cultural bias in testing
• Various factors can reduce validity/reliability of measures
• Language, fatigue, ADHD, mental illness, time of day, inexperience/lack
of training of evaluator, etc.

22
Q

Intellectual Disability

A

• Previously referred to as Mental Retardation
• Subaverage intellectual functioning, accompanied by
limitations in adaptive functioning
• IQ below 70 (mean=100, SD=15)
• Deficits in adaptive skills (self-care, work, social,
communication, health and safety)
• Must occur before 18
• Subtypes: IQ between…
• Mild: 50-55 and 70 (Mental Age:8-10 yrs); 85% of MR
• Moderate: 35-40 and 50-55 (MA: 4-7); 10% of MR
• Severe: 20-25 and 35-40 (MA:<4);3-4% of MR
• Profound Retardation: IQ below 20-25; 1-2% of MR

23

  • Drug/Alc exposure in utero
  • Brain trauma/injury
  • Radiation
  • Malnutrition
  • Other brain abnormalities
24

Giftedness

A

extraordinary talent or achievement in one or more areas
• In many school districts, above average IQ score is required (above 130 or 140)
plus high achievement in one or more areas
• Precocious, independent, voracious learners
• Internally driven to master their interest
