4. Types of Intelligence
• Naturalist (nature smart)
• Musical (sound smart)
• Logical-mathematical
(number/reasoning smart)
• Existential (life smart)
• Inter-personal (people smart)
• Bodily-kinesthetic (body

5. Tests Of Intelligence
•Alford BinetTest
•Wechsler’s test

6. Lewis Terman & William Stern
Stanford-Binet IQ Test
Stanford-Binet IntelligenceTest
IQ=(MA/CA)*100
IQ=Intelligence Quotient
MA=Mental Age
CA=Chronological Age
A score of 100 would be considered average
Formula has been replaced with modern
versions

7. David Wechsler (1896-1981)
• Developed theWechsler
intelligence scales which
included:
 Different tests for different
age groups
 Separate verbal and
nonverbal scores
 Subtests and subtest scores

8. TheWechsler tests
Modeled after Binet’s but improved it in
two ways.
1. Designed test for both adults and
children.
WISC-IV =Wechsler Intelligence Scale for children
WAIS-IV =WechslerAdult Intelligence Scale
2. Provided scores in 11 different subtests
for 11 abilities which were grouped to
show a performance and verbal score.
• It showed an individual’s strengths and weaknesses in a
variety of areas.

10. Testing Spatial Reasoning

11. What do IQ tests measure
about your mind?
•Mental speed and span of working memory
• typically use a digit span test to measure this
• more recent studies find significant correlations between reaction times and IQ scores
•Why is this important?
• mental quickness may expand capacity of
working memory which aids in problem solving

12. • IQTests do a good job measuring:
• Logical & Abstract thinking
• Problem solving
• Capacity to acquire knowledge
• IQTests however do not measure:
• Creativity – artistic ability
• Achievement motivation
• Goal-oriented behavior
• Ability to adapt to one’s
environment

13. Factors that Reduce Intelligence
• Poor nutrition
• Pollution
