Affirming the consequent; invalid

Finke and Pinker (1982)

-Task: Ps judge whether arrow points to dots previously seen -Result: Longer rxn time when greater distance between arrow and dot (as if they were "mentally travelling"); not instructed to use visual imagery; no time to memorize, no tacit knowledge

-Task: Ps studied map of hypothetical region until they could reproduce it; then estimated distance between specified pairs of cities -IV: 0, 1, 2, or 3 cities along the route between the 2 cities -Results: The # of intervening cities had a clean-cut influence on estimates; "cluttered" routes seem longer; roads with complex turns seem longer than straight roads

Kosslyn (1978)

-Task: Study figure of island with 7 locations, 21 trips -Results: It took longer to scan between greater distances -Implication: Visual imagery is spatial

Kosslyn (1973)

-Task: memorize picture, create an image of it; in image, move from one part of the picture to another -Result: it took longer for participants to mentally move long distances than shorter distances -Implication: like perception, imagery is spatial

A circular plate rests at the center of a small square table. Around the table are a total of four chairs, one along each side of the square table. A person with unilateral neglect sits down in one of the chairs and eats from the plate. After he is "finished," he moves to the next chair on his right and continues to eat from the plate. Assuming he never moves the plate and he continues with this procedure (moving one chair to the right and eating) how many chairs will he have to sit in to eat all the food on the plate?

Spatial

The Jam Experiment

Tasting 24 jams versus 6 jams. To sample the jam: 40% sampled the 6 and 60% sampled the 24. But when purchasing, 30% buy the 6 jams; 3% buy the 24 jams More shoppers purchased when variety was less

Satisficers

Tend to settle for something that is satisfactory

Prospect Theory

The evaluation of outcomes is defined on gains and losses rather than expected utility

Which of the following has been used as an argument AGAINST the idea that imagery is spatial in nature?

The tacit-knowledge explanation

Base-rate neglect

The tendency to ignore the overall likelihood that an event will occur, or that a case will belong in a given category. Emphasize representativeness and underemphasizes important information about base rates

Two-String problem

Tie two strings together hanging from different parts of ceiling. Use pliers to create a pendulum.

Falsification Principle

To test a rule, you must look for situations that falsify the rule; most participants fail to do this

Representativeness Heuristic

We judge that a sample is likely if it is similar to the population from which it was selected

Rotation Heuristic

We remember a tilted geographic structure as being either more vertical or more horizontal than it really is -Reno vs. San Diego -Seattle vs. Toronto -U.S./Canada Border

Alignment Heuristic

We remember geographic structures as being arranged in a straighter line than they really are

Tversky

We use heuristics when we represent relative positions in our mental maps

The Anchoring and Adjustment Heuristic

When making an estimate, we begin with a first approximation (anchor) and then we make adjustments to that number on the basis of additional information -People rely too heavily on the anchor and their adjustments are too small

Belief-Bias Effect

When people make judgments based on prior beliefs and general knowledge, rather than on the rules of logic.

Likelihood Ratio

Whether the description is more likely to apply to population A or population B

Functional Fixedness

Works against solving a problem, focusing on familiar functions or uses of an object.

Mental-walk task

a task used in imagery experiments in which participants are asked to form a mental image of an object and to imagine that they are walking toward this mental image Example: rabbit experiment, results provides futher evidence for the idea that images are spatial like perception

Dr. Curious is doing a follow-up study to the mutilated checkerboard problem experiment. In this new study, participants solve the following shoe problem before tackling the checkerboard problem. By doing this, Dr. Curious is studying the effect of ________ on problem solving. The shoe problem: A first-grade class is using a trampoline in gym class, so all the children have removed their shoes, which are all jumbled in a large pile. One of the students, Miguel, is leaving early, so the teacher tells him to grab his shoes and report to the lobby. In his hurry, Miguel grabs two identical left-footed, size 6 red sneakers and runs to his mother still sock-footed. Will the remaining students be able to shoe-up with the remaining shoes without getting a foot-ache?
