Exam 3 Ch. 8 Flashcards
It’s rarely possible to identify all the relevant factors that must be taken into account by solutions.
Open-endedness
With so many considerations being actually or potentially relevant, our limited mental capacity is quickly over-loaded.
Complexity
Many values must be served by solutions so difficult judgmental tradeoffs must inevitably be made.
Value tradeoffs
Because of the phenomena involved, it’s difficult to confidently predict future developments or the effects of proposed actions.
Outcome uncertainty
Methods covering the entire problem solving process.
Functional models
The mind’s ability to monitor and control its own functioning.
Metacognition
For instance, flexibility, open-mindedness, depth, breadth, soundness, clarity, validity, and freedom from bias.
Cognitive Virtues
The ability to conceive situations in fundamental terms so useful lessons can be derived from experience.
Abstraction
Factual, “what is the case” information that includes relevant concepts, principles, and pitfalls.
Declarative Knowledge
Action-oriented, “how to” knowledge that includes relevant methods, heuristics, and strategies. Ex: How to ride a bike.
Procedural Knowledge
Trial-and-error search for a solution among a limited set of possibilities.
Generate-and-test
Search that uses knowledge to direct attention to places where good solutions are most likely to be found.
Heuristic Search
Trying to reach a goal by a series of steps, based on local search, each leaving one closer to the goal than before.
Hill-climbing
Starting from the known goal-state of a problem and working backwards towards its initial state to identify a solution path.
Working backwards
A divide-and-conquer strategy that breaks large complex problems down into many small simple ones.
Decomposition
After graduating with a degree, you apply and get a job making $40,000. You apply for a job and accept the job making $45,000. You see an ad that you could make $60,000. You apply for that job and get it. You do not apply anywhere else because you do not see anywhere where you could make more.
Hill-climbing
Taking a car trip but have to be back in Cedar Falls by Monday, which means you need to be ing St. Louis by Sunday.
Working backwards
You are preparing a powerpoint. How many slides do I want and what do I want on each slide?
Decomposition
An informal method or good piece of advice, a quick-and-dirty way of performing a task that is often effective but which provides no guarantees. Ex: Cooking foods at low temperatures for long periods.
Heuristic
A failure to recognize that familiar objects can be used for novel purposes.
Functional Fixedness
A tendency to employ routine, mechanized responses to problem situations even when they aren’t appropriate.
Problem solving set
A stapler can be used for things other than just stapling paper.
Functional Fixedness
Represents what people actually do when solving a problem.
Descriptive model
Specifies what people should do to be effective problem solvers.
Prescriptive or normative model
