this problem, you should __________

D) You are fast if you have formed an image of the cat next to an ant
- Participants' use of "hill climbing" is evident in that:
C) problem solving often gets stalled if a problem requires the participant to move briefly away from the goal state in order (ultimately) to reach the goal.

A) the raw feel of an experience, reflecting how it feels to have the experience

A) the FU is in conflict with the conscious mind, while the CU cooperates with it
- Which of the following pieces of evidence provides really good evidence that visual images actually are patterns of neural activity in visual perception areas of the brain?
B) Evidence from PET scans about activity in the occipital lobe while imagining large vs. small size objects
- Solomon remembers how Jacob acted last weekend, and the weekend before that. Based on this, Solomon is trying to figure out whether there is a pattern to Jacob's actions. Solomon is working on a problem of:
A) induction
- People who report vivid imagery, compared to people who do not,
B) exhibit comparably fast mental rotation
- Studies of analogy use indicate that participants:
A) are more likely to use analogies if there is a superficial resemblance between the problem being solved and the problem serving as the base for the analogy.
- Which of the following statements is most nearly accurate?
C) images are organized depictions of objects
- If we form an image of a tiger, we (probably) can't count the stripes. This is probably because:
D) Images aren't pictures in the head
- Chess experts are better than novices at remembering chess piece configurations from real games because of
A) chunking
- The "expected utility" associated with an action:
D) is calculated as the utility of the likely outcome of the action multiplied by the probability of reaching that outcome.
- In memorizing new material (e.g., words with concrete referents), the pattern of "dual coding" refers to:
C) steps that lead to both a verbal memory and a visual memory.
- What is the Turing Test supposed to do?
C) tell you whether or not a computer is conscious OR
D) determine whether someone can distinguish the behavior of a computer from the behavior of a person
- It has been argued that you will take action based on a memory:
D) only if you are satisfied that the thought you are having is in fact an actual memory.
- People are likely to accept the following (invalid) logic: Some smokers get lung cancer; some lung cancer victims die young; therefore, some smokers die young. This illustrates
B) belief bias
- An "image file" refers to:
A) descriptive information in long-term memory used as the basis for creating an active image
- A problem's "initial state" refers to:
D) the knowledge and resources one possesses at the outset of the problem.
- Reasoning theorists claim that the problem of verifying "if a person is drinking beer, the person must be over 21 years old" (by checking out some people who are drinking beer vs. coke or who are young vs old) is easy
B) because it follows a "permission schema"
- Some "framing effect" phenomena in decision-making can be explained by assuming that:
B) subjective utility is an S-shaped function of objective value, with the fastest changes in subjective utility occurring at relatively small values of objective gain or loss
- A base rate is defined as:
A) information about the broad likelihood of a particular type of event
- Participants are more likely to judge a syllogism to be valid if:

- Which of the following is not a heuristic used in problem solving?
B) framing
- Which of the following is correct about our reasoning ability?

- Which of the following observations would be inconsistent with the claim that participants often use mental models to guide their reasoning?
A) If a problem's premises can be modeled in many different ways, the problem will be easier to solve.
- Which of the following cognitve processes is generally agreed to be conscious?
C) Explicit long-term memory.
- People who do research on problem solving have shown that one heuristic that can help people to solve problems is:
A) Try different ways of representing a problem if the first representation doesn't work well.
- One of the most important things in making an analogy useful in problem-solving involves:
D) finding the appropriate mapping between the structure of the analogy and the problem
- In using the "representativeness heuristic," participants:
D) seem to assume that all instances of the category resemble the prototype or average for that category.
- Which of the following is a normative principle that takes base rates into account in estimating conditional probabilities?
C) Bayes' rule
- Participants were presented with a group of numbers, such as "2, 4, 6," and were told that the numbers followed a certain rule. The participants' task was to determine the rule. Sam's hypothesis is this: "The second number must be two higher than the first, and the third number must be two higher than the second." To test his hypothesis, Sam asks the experimenter, "Does 14, 16, 18 fit with the rule?" Sam's question:
D) is consistent with the pattern called confirmation bias.
