A burst of right temporal lobe EEG activity (yellow area) accompanied insight solutions to word problems (Jung-Beeman et al., 2004).
The red dots show placement of the EEG electrodes. The light gray lines show patterns of brain activity during insight.

How would you arrange six matches to form four equilateral triangles?
An effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning
Asimple thinking strategy that often allows you to make judgments and solve problems efficiently; usually speedier but also more error prone than algorithms
A simple thinking strategy that often allows you to make judgments more error prone than algorithms
Involves judging the likelihood of an event based on its availability in memory; if an event comes readily to mind, we assume it must be common
Solution to the matchstickproblem Were you, by chance, fixated on two-dimensional solutions? Solving problems often requires taking a new angle on the situation.

NEW LANGUAGE LEARNING GETS HARDER WITH AGE Young children have a readiness to learn language. Ten years after coming to the United States, Asian immigrants took a grammar test. Those who arrived before age 8 understood American English grammar as well as native speakers
did. Those who arrived later did not. (From Johnson & Newport, 1991.)

________ is the part of the brain that, if damaged, might impair your ability to speak words.
If you damage ________ you might impair
your ability to understand language.
What is mental practice, and how can it help you to prepare for an upcoming event?
If your dog barks at a stranger at the front door, does this qualify as language? What if the dog yips in a telltale way to let you know that she needs to go out?
Matt Savage, an award-winning
jazz musician, is a BerkleeCollege of Music graduate who has released many albums.
His success has been hard-won given his early childhood diagnosis of what is now called autism spectrum disorder, which came with struggles to communicate and an initial inability to tolerate sounds of any kind.

What did Binethope to achieve by establishing a child’s mental age?
An employer with a pool of applicants for a single available position is interested in testing each applicant’s potential. She should use an ________ (achievement/aptitude) test. That same employer wishing to test the effectiveness of a new, on-the-job training program would be wise to use an _______ (achievement/aptitude) test.
What is the IQ of a 4-year-old with a mental age of 5?
Scores on aptitude tests tend to form a normal, or bell-shaped, curve around an average score. For the Wechsler scale, for example, the average score is 100.
THE NORMAL CURVE
What are the three requirements that a psychological test must meet in order to be widely accepted? Explain.
INTELLIGENCE: NATURE AND NURTURE The most genetically similar people have the most similar intelligence scores. Remember: 1.0 indicates
a perfect correlation; zero indicates no correlation at all. (Data from McGue et al., 1993.)

When Ian Deary and his colleagues (2004) retested 80-year-old Scots, using an intelligence test they had taken as 11-year-olds, their scores across seven decades correlated +.66.
(When 207 survivors were again retested at age 87, the correlation with their age 11 scores was +.51 [Gow et al., 2011].)
WITH AGE WE LOSE AND WE WIN Studies reveal that word power grows with age, while fluid intelligence declines.
Do the know the answer?
Even if the variation between members within a group reflects genetic differences, the average difference between groups may be wholly due to the environment. Imagine that seeds from the same mixture are sown in different soils. Although height differences within each window box of flowers will be genetic, the height difference between the two groups will be environmental. (From Lewontin, 1976.)

Might racial and ethnic gaps be similarly
The heritability of intelligence scores will be greater in a society marked by equal opportunity than in a society of poor peasants and wealthy aristocrats. Why?
