Brain size (adjusted for body size) is ________ correlated with intelligence. The speed of taking in perceptual information is ________ correlated with intelligence.

positively; positively

Intrinsic motivation is thought to be an important component of


When highly skilled people are performing a task, their brains

1. retrieve information from memory more quickly.
2. register simple stimuli more quickly.
3. demonstrate a more complex brain-wave response to stimuli.

Studies suggest that there is a positive correlation between intelligence and the brain's

neural processing speed.

Current intelligence tests compute an individual's intelligence score as

the amount by which the test-takers performance deviates from the average performance of others the same age.

Some studies indicate that a rough indicator of infants' later intelligence is their

preference for looking at a new rather than an old picture.

A psychologist who is looking at a student's intelligence score finds a jump of 30 points between the earliest score at age 2 and the most recent at age 17. The psychologist's knowledge of testing would probably lead her to conclude that such a jump

is mainly the result of the age at which the first test was taken.

Your psychology professor has announced that the next test will assess your understanding of sensation and perception. When you receive the test, however, you find that very few questions actually relate to these topics. In this instance, you would be most concerned about the ________ of the test.

content validity

In an emergency situation, emotional arousal will result in

1. increased blood sugar.
2. increased rate of respiration.
3. a slowing of digestion.

The polygraph measures the changes in ________ that accompany emotion.

heart rate

Emotions consist of which of the following components?

1. behavioral expressions
2. physiological reactions
3. conscious feelings

The autonomic nervous system regulates the ________ that accompanies different emotions.

physiological arousal

North Americans are more likely than Japanese citizens to display their feelings openly. This cultural difference best reflects the American culture's greater emphasis on


Who is the LEAST likely to display personal emotions openly?

Yoko, a dentist in Japan

If you grimace in fear while taking a difficult exam, this facial expression is likely to cause

you to experience increasingly intense feelings of fear.

Vanessa is a very creative sculptress. We would expect that Vanessa also

has a venturesome personality and is intrinsically motivated.

Gerardeen has superb social skills, manages conflicts well, and has great empathy for her friends and co-workers. John Mayer, Peter Salovey, and David Caruso would probably say that Gerardeen possesses a high degree of

emotional intelligence.

L. L. Thurstone identified seven clusters of primary mental abilities, including word fluency, memory, and inductive reasoning. He claimed that word fluency

involves a different dimension of intelligence from that of reasoning.

The existence of ________ reinforces the generally accepted notion that intelligence is a multidimensional quality.

savant syndrome

Amelia recently took a test that assessed her ability to perform at the university level. The test she took was the


The correlation between academic success and intelligence test scores will be LOWEST if computed for a group of individuals whose scores range between

85 and 115.

Five-year-old Benjy has an IQ of 120 on the original version of the Stanford-Binet. His mental age is


For the original version of the Stanford-Binet, IQ was defined as

mental age divided by chronological age and multiplied by 100.

A student participating in an experiment concerned with physical responses that accompany emotions reports that her mouth is dry, her heart is racing, and she feels flushed. Can the emotion she is experiencing be determined?

No, it cannot be determined from the information given.

Activation of the sympathetic nervous system

increases respiration and decreases salivation.

One problem with the use of the polygraph for lie detection is that

anxiety, irritation, and guilt feelings all prompt similar physiological reactivity.

Which theory of emotion implies that every emotion is associated with a unique physiological reaction?

James-Lange theory

The candidate stepped before the hostile audience, panic written all over his face. It is likely that the candidate's facial expression caused him to experience

an intensification of his fear.

Researchers who explore emotion from a social-cultural level of analysis are especially likely to emphasize cultural differences in

emotional expressiveness.

Which of the following is true regarding gestures and facial expressions?

Facial expressions are universal; gestures, culture-specific.

Research on intelligence and brain anatomy indicates that highly intelligent children demonstrate ______ than their less intelligent counterparts.

greater neural plasticity

Melvin has been diagnosed as having savant syndrome, which means that he

is limited in mental ability but has one exceptional ability.

To assess whether intelligence is a single trait or a collection of several distinct abilities, psychologists have made extensive use of

factor analysis.

Injury to the left ________ lobe damages the convergent thinking required for successful performance on intelligence tests.


Jack takes the same test of mechanical reasoning on several different days and gets virtually identical scores. This suggests that the test has

high reliability.

Amelia recently took a test that assessed her ability to perform at the university level. The test she took was the


Studies of infants show that babies who quickly become bored with a picture

score higher on intelligence tests many years later.

If a test yields consistent results every time it is used, it has a high degree of


The basic components of emotion are

expressive behaviors, physiological arousal, and conscious experience.

According to the Cannon-Bard theory, the experience of an emotion

occurs simultaneously with physiological arousal.

A polygraph examination of a suspected murderer included an assessment of his reaction to a detailed description of the victim's clothing and death wounds—details that would be known only to a person at the scene of the crime. The investigators were using

the guilty knowledge test.

Which theory would be most threatened by evidence that highly similar patterns of physiological activity are associated with uniquely different emotional states?

the James-Lange theory

Patients reportedly feel less depressed following between-the-eyebrows Botox injections that immobilize their frown muscles. This best illustrates

the facial feedback effect.

Imitating another person's facial expression of emotion is most likely to facilitate


The fact that people from widely different cultures display and interpret facial expressions of emotion in a similar manner best illustrates the impact of

human genetic similarities.
