Final Flashcards
A desired state; provides the direction for problem-solving behavior
goal
A goal undertaken in the service of another goal
subgoal
An action that changes one problem state into another
operator
Based on transcripts of subjects ask to “think aloud” while solving problems
protocol analysis
The set of possible states that could be generated by applying all available operators to the current state, repeating for all the resulting states, and so on until the goal state is reached.
problem space
Representation of the situation at the start of solving a problem
initial state
Representation of the present situation in a problem solving task.
current state
Representation of the desired situation in a problem-solving task.
goal state
A sequence of states through a problem space leading from the initial state to the goal state
solution path
Represents operators in the form of condition-action rules
production rule
Searching for a goal sate by generating the entire problem space
exhaustive search
A problem solving strategy in which operators are selected to decrease the difference between the current state and the goal state
difference reduction
A problem solving strategy in which blocked operators lead to the creation of new subgoals
means-end analysis
A tendency to see the conventional uses of familiar objects, and to fail to see novel uses
functional fixedness
A tendency to continue using a familiar procedure to solve new problems, which may interfere with discovering more efficient procedures
set effects
refers to the fact that an infinite number of utterances are theoretically possible in any human language
