2. A Snail is at the bottom of a well 30 feet deep
A Snail is at the bottom of a well 30 feet deep. It can crawl upward 3 feet in one day, but at night it slips back two feet. How long does it take to crawl out of the well?
There are two jars of equal capacity. In the first jar there is one amoeba. In the second jar there are two amebas. An amoeba can reproduce itself in three minutes. It takes two amoebas in the second jar three hours to fill the jar to capacity. How long does it take the one amoeba in the first jar to fill that jar to capacity?

3. 1.) Intelligence (in all cultures) is the ability to learn from experience, solve problems, and use our knowledge to adapt to new situations.
***In research studies, intelligence is whatever the intelligence test measures. This tends to be “school smarts.”
OBJECTIVE 1| Discuss the difficulty of defining intelligence, and explain what it means to “reify intelligence.”.

4. a.) Psychologists believe that intelligence is a concept and not a thing.
b.) reification — viewing an abstract immaterial concept as if it were a concrete thing.

5. ***Controversies About Intelligence
Despite general agreement among psychologists about the nature of intelligence, two controversies remain:
Is intelligence a single overall ability or is it several specific abilities?
With modern neuroscience techniques, can we locate and measure intelligence within the brain?

6. ***Intelligence: Ability or Abilities?
Have you ever thought that since people’s mental abilities are so diverse, it may not be justifiable to label those abilities with only one word, intelligence?
You may speculate that diverse abilities represent different kinds of intelligences. How can you test this idea?

7. A camp cook wants to measure four ounces of vinegar out of a jug, but he has only a five-ounce and a three-ounce container. How can he do it?

8. Athleticism, like intelligence, is many things
2.) The idea that general intelligence (g) exists comes from the work of Charles Spearman ( ) who helped develop the factor analysis approach in statistics.
OBJECTIVE 2| Present arguments for and against considering intelligence as on general mental ability.
Athleticism, like intelligence, is many things

9. a.) Spearman proposed that general intelligence (g) is linked to many clusters that can be analyzed by factor analysis.
***For example, people who do well on vocabulary examinations do well on paragraph comprehension examinations, a cluster that helps define verbal intelligence. Other factors include a spatial ability factor, or a reasoning ability factor.

10. A race driver drove around a 6-mile track at 140 mph for three miles, 168 mph for 1 ½ miles, and 210 mph for 1 ½ miles. What was his average speed for the entire 6 miles?

11. b.) seven clusters of primary mental abilities, including:
L. L. Thurstone, a critic of Spearman, analyzed his subjects NOT on a single scale of general intelligence, but on
b.) seven clusters of primary mental abilities, including:
Word Fluency
Verbal Comprehension
Spatial Ability
Perceptual Speed
Numerical Ability
Inductive Reasoning
Memory

12. c.) Later psychologists analyzed Thurstone’s data and found a weak relationship between these clusters, suggesting some evidence of a g factor.
