Question 1

For his independent project in Cooking 101, Henry decides to develop a new dip for raw vegetables, using sour cream and herbs. He tries one combination of ingredients after another, adjusting the seasoning as he goes along. What problem-solving strategy is Henry using?

Accepted Answer

Henry is using a trial-and-error strategy by modifying his dip recipe through different combinations of ingredients and adjusting the seasoning until he comes up with the desired taste and consistency.

Question 2

After his imported, top-rated, 15-speed mountain bike is stolen, Jason decides to replace it with the least expensive 10-speed he can find so that he won't have to worry about it. Which decision-making strategy is Jason using?

Accepted Answer

Jason has focused on only one feature, which is the cost, and made the decision accordingly. This aligns with the single-feature model.

Question 3

A well-designed psychological test has which of the following characteristics?

Accepted Answer

A well-designed psychological test should have reliability, meaning it consistently produces similar results when administered to the same person multiple times, standardization, meaning it is administered and scored in a consistent manner across different individuals, and validity, meaning it accurately measures what it is intended to measure. Option C includes all three of these characteristics, while the other options only include two. Option D includes standardization, validity, and variability, but the concept of variability is not typically considered a key characteristic of a well-designed psychological test. Option B includes verification, which is not a commonly discussed characteristic of psychological tests.

Question 4

Several problems have been assigned as part of your physics homework. One problem asks you to determine the relative velocity of a variety of moving objects. To answer the question, you solve a complex mathematical equation. Which problem-solving strategy are you using?

Accepted Answer

Using a complex mathematical equation to solve the problem indicates the use of an algorithm, which is a step-by-step procedure for solving a specific problem. A heuristic involves using a general rule of thumb or educated guess, whereas trial-and-error involves repeated attempts at solving a problem until a solution is found. Insight involves suddenly realizing the solution to a problem without consciously working through the steps.

Question 5

Dividing a person's mental age by chronological age and multiplying the answer by 100 is:

Accepted Answer

Dividing a person's mental age by chronological age and multiplying the answer by 100 is Louis Terman's formula for the IQ score as measured by the Stanford-Binet Intelligence Scale. This formula is used to determine a person's intelligence quotient (IQ) score, which is a standardized measure of cognitive ability.

Question 6

Erika is asked to generate a list of five different animals that can be kept as pets. She quickly responds, "dogs, cats, goldfish, gerbils, and canaries." Dogs would thus represent Erika's _____ for the _____ concept of pets.

Accepted Answer

Dogs are often considered a typical example or prototype of the natural concept of pets, as they are commonly associated with the idea of a pet.

Question 7

A new friend asks you to describe the house you grew up in. You pause and think for a moment. You will need to use_____ to answer her question.

Accepted Answer

Mental images are the best choice as they involve recalling and visualizing specific details about the house one grew up in. This would help in providing an accurate description of the house. Intuition, exemplars, and prototypes do not necessarily involve recalling specific details and may not provide an accurate description of the house.

Question 8

Emily is planning a trip to northern Canada in January. She decides to buy the warmest coat she can find, no matter what its cost or appearance. Emily is relying upon the _____ to decide which coat to buy.

Accepted Answer

Emily is using a single-feature model where she is only considering the warmth of the coat as the deciding factor.

Question 9

In which area of psychology are twin studies typically used?

Accepted Answer

Twin studies are typically used in the area of psychology to determine the relative contributions of genetic and environmental factors to intelligence and other characteristics. By comparing identical twins (who share 100% of their genes) to fraternal twins (who share only 50% of their genes on average), researchers can estimate the degree to which genetic factors contribute to individual differences in traits like intelligence, personality, and behavior.

Question 10

Rick asks you how many stop signs you encounter on your drive home. To answer his question, you probably rely on a:

Accepted Answer

When recalling the number of stop signs encountered on a drive home, most people rely on a mental image of the route they take and where the stop signs are located. This information is stored in their memory and retrieved through mental imagery, making A the best answer.

Question 11

Cissy likes to drive fast, counting on her matronly appearance and southern charm to avoid getting a speeding ticket. She believes that most speeders who get tickets are young males driving high-performance cars, so she is surprised when an officer pulls her over and gives her a $200 speeding ticket, despite the fact that she has three kids in her SUV with soccer balls and uniforms in the back. Cissy was misled by _____ in her belief that she was highly unlikely to get a speeding ticket.

Accepted Answer

Cissy was misled by the representativeness heuristic in her belief that she was highly unlikely to get a speeding ticket because she based her belief on the stereotype that young males driving high-performance cars are the ones who get tickets, whereas in reality, any driver can receive a speeding ticket regardless of their appearance or age.

Question 12

Emma overheard the driver education instructor rant and rave about how the girls in Emma's group were the worst drivers he'd ever had the misfortune to teach in his 30 years of teaching high school students to drive. When it was Emma's turn to practice her driving skills with the instructor, she performed worse than usual, forgetting to use turn signals, turning the wheel the wrong way when backing up, and running over two plastic cones when attempting to parallel park. What is the MOST likely explanation for Emma's poor performance behind the wheel?

Accepted Answer

Emma's poor performance can be explained by the influence of stereotype threat. After overhearing the instructor's negative comments about the girls in her group, Emma may have internalized those stereotypes and felt like she was unable to perform well behind the wheel because of her gender. This can lead to anxiety and can impair performance. This phenomenon is called stereotype threat.

Question 13

In the model of intuition described in your text, which stage involves conscious, analytic thinking?

Accepted Answer

The integrative stage involves conscious, analytic thinking where the intuitive insights are evaluated and integrated into a coherent understanding.

Question 14

Psychologist _____ strongly believed that all mental abilities were related to a single common factor called the _____ factor.

Accepted Answer

The psychologist who strongly believed that all mental abilities were related to a single common factor called the general intelligence or g factor is Charles Spearman.

Question 15

_____ is formally defined as the mental activities involved in acquiring, retaining, and using knowledge, including memory and perception.

Accepted Answer

Cognition is specifically defined as the mental processes involved in gaining knowledge and understanding through thought, experience, and the senses. Thinking, motivation, and problem solving are all important components of cognition, but do not encompass the full range of cognitive activities.

Question 16

"The global capacity to think rationally, act purposefully, and deal effectively with the environment" is:

Accepted Answer

This definition aligns with Wechsler's definition of intelligence, which emphasizes an individual's capacity to think rationally and adapt to the environment. Sternberg's definition of successful problem solving is more specific to the process of problem solving, Gardner's definition of logical-mathematical intelligence is focused on a specific type of intelligence, and Thurstone's definition of intelligence includes multiple factors such as verbal comprehension and spatial ability.

Question 17

Your text describes research involving participants who lived in remote Amazon tribes and spoke languages that lacked a counting system or specific words for numbers. What conclusion did the researchers reach?

Accepted Answer

The researchers concluded that the lack of a number concept and specific words for numbers in the Amazon tribes caused them to only be able to use relative terms like few, some, and many when describing quantities. This suggests that language categories can affect how individuals think about particular concepts.

Question 18

One day Ethan had "a feeling" that he was going to get a phone call from a long-lost friend. That evening, an old high school classmate called, inviting him to attend a class reunion. Now Ethan is telling everyone that he is psychic. According to your textbook, which cognitive bias provides the best explanation for Ethan's belief?

Accepted Answer

The fallacy of positive instances refers to the tendency to remember or notice coincidences or events that confirm our beliefs while ignoring those that do not. Ethan is focusing on the coincidence of his feeling and the call, ignoring other times he had similar feelings without any calls.

Question 19

The term heritability refers to the:

Accepted Answer

Heritability refers to the percentage of variation within a particular population that is due to heredity, which means how much of a particular trait can be attributed to genetic factors. It does not refer to specific populations or individuals.

Question 20

A friend asks you which three books you would take if you knew you were going to be marooned on a desert island for a year. Because language has the characteristic of _____, you are able to have a meaningful conversation about the topic, even though you're not really marooned on a desert island.

Accepted Answer

Displacement is the characteristic of language that allows us to talk about things that are not present or events that are not currently happening, enabling us to discuss hypothetical situations like being marooned on a desert island.
