Problem Solving and Intelligence
Problem Solving
Process in which a person begins with a goal and seeks some steps that will lead toward that goal.
Problem Space
Set of all states that can be reached in solving the problem.
Hill-Climbing Strategy
Used in problem-solving; when they are given a choice, they will choose the option that carries them closer to the goal. This is a heuristic.
Means-End Analysis
Where person is guided step-by-step, by a comparison of the difference at that moment, between the current state and the goal state. Breaking a problem down to solve it.
Mapping
Process of figuring out how aspects of one situation or argument correspond to aspects of some other situation or argument.
Ill-Defined
No clear statement at the outset of how the goal should be characterized or what operations might be used to reach that goal.
Functional Fixedness
Tendency to be rigid in how one thinks about an object’s function.
Problem-Solving Set
Collection of beliefs and assumptions a person makes about a problem.
Einstellung
German word for attitude, to describe the problem-solver’s perspective (beliefs, habits, etc.).
Preparation (First Stage)
Problem solver gathers information about the problem.
Incubation (Second Stage)
Problem solver sets the problem aside and seems not to be working on it.
Illumination (Third Stage)
Where a key insight or new idea emerges.
Verification (Fourth Stage)
Where the person confirms that the new idea really does lead to a problem solution and works out the details.
Reliability
How consistent a measure is; consistency from one occasion to another.
Test-Retest Reliability
Assessment of whether a test is consistent in what it measures, determined by asking whether the test’s results on one occasion are correlated with results from the same test on another occasion.
Validity
Whether a test measures what it is intended to measure.
Predictive Validity
Assessment of whether a test measures what it is intended to measure, based on whether the test scores correlate with some other relevant criterion.
Factor Analysis
Looks for common factors, elements that contribute to multiple subtests and which therefore link those subtests.
