3 approaches to problem solving
Gestalt approach
Problem solving as search
Knowledge and problem solving
What is the Gestalt Approach?
Emphasises importance of changes in perspective, prior knowledge and assumptions
What is problem solving as search?
Problem solving as a search through a problem space of possibilities; start with situation we want to transform into something new and do so by applying different options we have
What are general problem solving methods?
A procedure for performing a search for a solution, but how to find solution may not be clear, therefore use heuristic strategies
What is functional fixity?
We develop mental sets: tend to see things in a certain way, use certain solutions
What is means-end analysis?
Compare the current state to goal state and identifying differences. Set sub goals in order to reach main goal
E.g. getting a plane to brisbane
What are insight problems?
They require a change in representation in order to solve
Define transfer
The application of old knowledge to a new problem
Define negative transfer
Transfer using functional fixedness and mental set
Define positive transfer
Transfer using prior knowledge to help you solve a problem
Define analogies
Relationships between two similar situations, problems or concepts
What age groups discount the future more?
Kids (12 years) discount more than young adults (20 yrs) and then older (70 years)
Define expected utility hypothesis
The utility of an agent facing uncertainty is calculated by considering utility in each possible state and constructing a weighted average, where the weights are the agent’s estimate of the probability of each state
Problems with the expected utility theory
Probabilities and utilities may be subjective, based on our own experience; often doesn’t fit to empirical data
Define base-rate neglect
Sometimes people ignore useful information, even if it is explicit
