Functional fixedness arises because of what?

one's problem solving set

Identify each heuristic the problem solver is using in these descriptions.

1) Camilla is headed north to visit her mother in Santa Barbara. When she leaves her house, she drives north for an extra 15 minutes in order to get to the freeway even though there was an on-ramp 2 minutes south of her house - hill climbing strategy
2) Roscoe, an energetic beagle puppy, has gotten his leash wrapped around a street light. He keeps pulling forward trying to get free, but it doesn't occur to him to retrace his steps in order to unwrap the leash. - hill climbing strategy
3) Juan needs to move a heavy stack of barbell plates—stacked with the largest on the bottom and smallest on top—to the other side of the recreation space. First, he has to take the smaller plates off and put them to the side in order to move the bigger plates to the other side. Then, he picks up the smaller plates in reverse to stack them on top of the bigger ones. - means end analysis
4) Jax is trying to get from Chicago to D.C. for a business trip. A flight will get him from Chicago to D.C., but how to arrange the flight? He'll need to find a computer to book the ticket, then he'll need to arrange a ride to the airport. He makes a list of other tasks he needs to complete in order to make it to D.C. - means end analysis

Participants were given a candle, a book of matches, and a box of tacks. Their task was to find a way to attach the candle to the wall of the room, at eye level, so that it would burn properly and illuminate the room. One group of participants received a box full of tacks, while the other group received the tacks alongside the empty box. Which group was able to solve the problem?

participants who were provided with the matches, the candle, a pile of tacks, and an empty box

Identify the problems that are "insight problems"

1) A stranger approached a museum curator and offered him an ancient bronze coin. The coin had an authentic appearance and was marked with the date 544 B.C. The curator had happily made acquisitions from suspicious sources before, but this time he promptly called the police and had the stranger arrested. Why? - insight
2) A landscape gardener is given instructions to plant four special trees so that each one is exactly the same distance from each of the others. How should the trees be arranged? - noninsight
3) insight
4) noninsight
5) insight

Map the components of the "general and fortress" story onto the tumor problem.

tumor - fortress
healthy tissue - neighboring villages
rays - soldiers
intensity of the rays - # of soldiers
the doctor - the general
direction of the rays - roads with mines

Some participants were only given the tumor problem to solve without the initial story. Label the bar graph based on the information that was provided.

green - no analogy provided
orange - analogy provided, but no suggestion to use it
blue - analogy provided with suggestion to use it

Expert chess players, average players, and novice players were shown this and other similar arrangements of chess pieces on a board for 5 seconds.
Which of these statements accurately describe the outcome of this study?

experts remembered the pieces based on tactical plays
average players and novices tried to remember the board as a whole

Which of these statements about individual differences in problem solving are true?

people who are better problem solvers are more likely to use analogies
experts are more likely than novices to think about a problem's deep structure

Which of these more recent findings are consistent with Wallas's proposal and which are inconsistent?

certain types of problems ("insight problems") are often solvled in an Aha moment
"mind wandering" can make incubation effects more likely

Revise these statements comparing creative people and less creative people to correct any errors. If the statements are correct, select the "No Errors" button.

Relative to less creative people, highly creative people:
- have relatively GREATER working memory capacity
- tend to generate MORE ideas
- are skilled in convergent AND divergent thinking
- are usually MORE willing to take risks
- are BETTER at searching their memories for ideas

Each of these people is describing a creative friend. Does the description suggest that the friend is skilled in convergent thinking or divergent thinking?

1) "I was just going to toss these old coffee filters that I never use, but Alex suggested dyeing them and making them into fake flowers as a decoration. They ended up really cute." - divergent
2) "Berta is the best researcher in our lab. She always connects ideas from different articles and classes that she's taken to her experiments; it has led to some really interesting findings." - convergent
3) "Peyton locked herself out of her car, but she cut a hole in a tennis ball and pushed it over the lock to exert enough pressure to open it. That hack is genius." - divergent

Which of these individuals are overcoming functional fixedness?

Ellen just moved and can't find her corkscrew in any of the moving boxes. To open a bottle of wine, she instead uses a bike pump, pumping air into the bottle until the cork dislodges.
Alvin is trying to move a very heavy bookcase, but it won't budge. He slides a metal cookie sheet underneath it and now he can move it across the carpet easily!

Kennan has just started his engineering homework and has come across a particularly difficult problem. After 10 minutes, he is still stuck. Based on the discussion of incubation in your textbook, which of these tactics could you reasonably recommend?

- keep trying
- go do something else
- stop trying and daydream for a bit
- take a nap then try again

Adam is participating in an experiment on "Aha!" moments during problem solving. As he works on each insight problem, he conveys his progress by providing warmth ratings ("I'm getting warmer . . . , I'm getting warmer . . . , I'm getting hot!") on a 0-10 scale.
Based on the ratings, select the point on the graph when Adam suspected that he was about to solve this problem.

at time of solution

Identify these problem-solving behaviors as more characteristic of experts, more characteristic of novices, or equally characteristic.

set subgoals - experts
frequently use analogies - experts
categorize new problems based on deep features - experts
use problem solving heuristics - equally
categorize new prolems based on surface features - novices

When confronted with an ill-defined problem, what can you do to make it more solvable?

create well-defined subgoals
add assumptions

Which of these does a problem space include?

states that lead to a solution
states that do not lead to a solution

In chess, which move is best at any point in the game depends on what your opponent will be able to do in response to your move, and then what you'll do next. To make sure you're choosing the best move, you need to think ahead through a few cycles of play. Once the game is under way, though, there will be roughly 700 million possibilities for how the game could unfold over only three cycles of play.
What can we learn about the problem-solving process from this?

a problem solver needs a way to narrow the search through a problem space

Participants are more likely to solve the tumor problem if they are advised to use the "general and fortress" story as an aid. When participants are not explicitly advised to use this analogy, how many solve the tumor problem?

30

In one study, participants were given a series of "insight problems" to solve. As participants worked on each problem, they rated their progress by using a judgment of "warmth" ("I'm getting warmer . . . , I'm getting warmer . . .").

when you say "aha" it means youve discovered a new approach

According to Wallas (1926), creative thought proceeds through four stages. Identify the stage in which each problem solver seems to be at the moment.

1) J.J. is trying to write his English Literature term paper, but he's experiencing "writer's block." He gives up after a couple of hours to go to the gym instead. - incubation
2) Kyra looked all over for the book that she borrowed from her professor, but she can't find it anywhere. During a conversation the next day about nearby restaurants, it suddenly hits her: She left it in the dining hall restroom! - illumination
3) Monroe needs to move to Ohio to start his new job next month. He searches online for different moving companies to get quotes and he starts to look around his apartment for things he can donate instead of taking with him. - preparation
4) Lena has been struggling to figure out a proof for her Calculus class for several days, but she thinks she finally has the solution. She double-checks her work—seems to be correct! - verification
