Thinking
going beyond the info you were given to reach a goal (solution, belief, decision)
problem solving
processes necessary to reach a goal, typically in situations where the solution is not immediately obvious
What are the 3 parts of problem solving
1) initial state
2) goal state
3) obstacles
initial state
situation at the beginning of the problem
goal state
when you solve the problem
obstacles
restrictions that make it difficult to proceed from the initial state to the goal state
understanding
when you have constructed a well-organized mental representation of the problem based on both the information provided in the problem and your own previous experience
Problem Representation
the way you translate the elements of the problem in to a different format
what do better representations give you?
better problem solving
How does good working memory help with representations
better representations
symbols
using symbols can help us understand problems, but we often use them incorrectly
matrix
a grid consisting of rows and columns
What is a matrix good for
diagrams
allow you to represent abstract info in a concrete way and discard unnecessary details
hierarchical tree diagram
tree-like structure to show various options in a problem which helps you understand a problem
visual images
allow us to escape from the boundaries of traditional, concrete representations
also helps construct a figure
situated cognition approach
we use helpful information in our immediate environment to create spatial representations
embodied cognition
use our body and motor actions in order to express our abstract thoughts and knowledge
how does situated cognition impact our problem solving
our ability to solve problems is tied into the specific physical and social context in which we learned to solve that problem (intelligence tests may not represent real world applications of problem solving)
Embodied cognition and problem solving
people perform better on tasks when they are allowed to use their hands
physical priming
when solving problems, physical priming can occur when we use our bodies in a particular way which may help us on a later test (swinging our arms in a warm can help us solve a pendulum problem faster)
algorithm
will always produce a solution, but can be inefficient
exhaustive search
try out all possible answers using a specified system
what are the benefits and negatives of using heuristics
using a heuristic strategy allows you to ignore unlikely alternatives which leads to faster solutions, but may not provide the correct answer
