Problem Solving

Some Basics
![Page 3: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/3.jpg)
Cognition—the mental activities associated with thinking, knowing, remembering, and communicating
![Page 4: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/4.jpg)
SOME BASICS
Concepts—a mental grouping of similar objects, events, ideas, or people
Prototypes—a mental image or best example of a category. Matching new items to a
prototype provides a quick and easy method for sorting items into categories
![Page 5: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/5.jpg)
ACTIVITY 1: What is prototypical? Give the best example (or first example that comes to mind) when given the following categories. After you write down your answers (in packet), proceed to the next slide.
1. A bird
2. A color
3. A triangle
4. A motor vehicle
5. A sentence
6. A hero
7. A heroic action
8. A game
9. A philosopher
10. A writer
![Page 6: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/6.jpg)
There are no “right” answers, but these are the most common responses, or the most prototypical
responses.
1. A bird: a robin, sparrow, or eagle
2. A color: red or blue
3. A triangle: a picture of an equilateral triangle
4. A motor vehicle: a car
5. A sentence: a short declarative sentence
6. A hero: Superman or Batman…possible fireman
7. A heroic action: a single act by a male
8. A game: Monopoly
9. A philosopher: Socrates or Aristotle
10. A writer: Stephen King…white, male author

The table below moves from prototypical to atypical—some of which we wouldn’t even place in a category
of “vehicles” or “fruits.”
![Page 8: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/8.jpg)
Which are cups, vases, or bowls? Your answer depends on your prototype for each.
![Page 9: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/9.jpg)
Problem-Solving—process of cognition that occurs when a goal must be reached by thinking and behaving in certain ways.
![Page 10: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/10.jpg)
DID YOU USE ANY OF THESE AS YOU ATTEMPTED TO SOLVE THE PUZZLES/BRAIN-TEASERS? TIPS FOR PROBLEM-SOLVING
1. Work backwards2. Recognize irrelevant information3. Graphic illustrations4. Restate the problem5. Insight and incubation6. Avoid unnecessary constraints

Cross out six letters to make a single word out of the following:
C S R I E X L E A T T T E R E S
You must cross out the “S,” the “I,” the “X,” the “L”…and so on—all of the letters that comprise “Six Letters.”
The remaining letters spell: CREATE.

#2: Husbands and Wives
Three men—Fred, Ed, and Ted—are married to Joan, Sally, and Vickie, but not
necessarily in that order. Joan, who is Ed’s sister, lives in Detroit. Fred
dislikes animals. Ed weighs more than the man who is married to Vickie. The
man married to Sally breeds Siamese cats as a hobby. Fred commutes over 200
hours a year from his home in Ann Arbor, Michigan to his job in Detroit. Match up the men with the women they married.

PROBLEM-SOLVING STRATEGIES
Trial and error—problem-solving method in which one possible solution after another is
tried until a successful one is found
![Page 16: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/16.jpg)
PROBLEM-SOLVING STRATEGIES
Algorithms—a methodical, logical rule or procedure that guarantees solving a particular
problem. This contrasts with the usually speedier—but more error—use of heuristics
It is a rule that guarantees an
answer, usually by way of a formula.
![Page 18: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/18.jpg)

PROBLEM-SOLVING STRATEGIES
Heuristic—a simple thinking strategy that often allows us to make judgments and solve
problems efficiently; usually speedier but more error-prone that algorithms…more on
this later.

PROBLEM-SOLVING STRATEGIES
Rule of thumb—a general rule that fits most situations
![Page 23: 83: January 13](https://reader034.vdocument.in/reader034/viewer/2022042607/55a2ffa91a28ab204d8b45a3/html5/thumbnails/23.jpg)

PROBLEM-SOLVING STRATEGIES
Insight—a sudden and often novel realization of the solution to a problem; it contrasts with
strategy-based solutions
This is like Skinner’s pigeon who suddenly got the idea to use the box as a stool to get the hanging fruit.

Convergent thinking—type of thinking in which a problem is seen as having only one
answer, and all lines of thinking will eventually lead to that single answer, using
previous knowledge and logic.
Divergent thinking—type of thinking in which a person starts from one point and comes up with many different ideas or
possibilities based on that point.

Mental set—a tendency to approach a problem in one particular way, often a way
that has been successful in the past
Functional fixedness—the tendency to think of things only in terms of their usual functions; an impediment to problem
solving
OBSTACLES TO PROBLEM SOLVING
Fixation—the inability to see a problem from a new perspective by employing a different
mental set

Intuition—an effortless, immediate, automatic feeling or thought, as contrasted
with explicit conscious reasoning

A bat and a ball
A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does
the ball cost?
Next slide will reveal answer.

A bat and a ball
The bat costs $1.05; the ball costs 5 cents. Did you get it wrong? Lots of people do.
Intuition can steer us wrong.
Next slide will reveal answer.

Overconfidence—the tendency to be more confident than correct—to overestimate the
accuracy of our beliefs and judgments

Fact: only 50% of people in any particular field can be above average.
Fact: 80% of the people in the US describe themselves as above average.
(Therefore, 30% of Americans have an unrealistic view of their abilities.)

Representative heuristic—judging the likelihood of things in terms of how well
they seem to represent, or match, particular prototypes; this may lead us to ignore other
relevant information

Who went to Harvard?
Sonia Dara did. A 2013 grad. She probably doesn’t not fit/”represent” our image of a
Harvard student.

Availability heuristics—estimating the likelihood of events based on their
availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are
common

Earlier this year, Ebola seemed to be sweeping the world. You might be surprised to know that you have a 1:13.3
million chance of contracting Ebola.
To put this in perspective, you have a 1:3.7 million chance of being killed by a shark in your lifetime.
AVAILABILITY HEURISTIC affects our thinking. See more on link at the bottom of the lesson
to see Ebola statistics.

Availability Heuristic
Why does our availability heuristic lead us astray?If it is easy to recall (remember), the probability or
frequency must be very high.
How is retrieval facilitated?
1. How recently we have heard about the event.
2. How distinct it is.
3. How correct it is.

Belief perseverance—clinging to one’s initial conceptions after the basis on which they
were formed has been discredited

Framing—the way an issue is posed; how an issue is framed can significantly affect
decisions and judgments
