A problem occurs when there is an obstacle between a present
state and a goal and it is not immediately obvious how to get around the obstacle.
A problem is a situation in which
you need to accomplish a goal and the solution is not immediately obvious.
Gestaltapproach was about (1) how people represent a problem in
their mind and (2) how solving a problem involves a reorganization or restructuring of this representation.
The Gestalt psychologists called the process of changing the problem’s representation restructuring.
Insight has been defined as any sudden comprehension, realization, or problem solution that involves a reorganization of a person’s mental representation of a stimulus, situation, or event to yield an interpretation that was not initially obvious.
Two Insight Problems: Triangle Problem and Chain Problem
Analyticallybasedproblems are solved by a process of systematic analysis, often using techniques based on past experience.
Fixation is people’s tendency to focus on a specific characteristic of the
problem that keeps them from arriving at a solution.
One type of fixation that can work against solving a problem, focusing on familiar functions or uses of an object, is called functional fixedness.
Examples of functional fixedness: candleproblem and two string problem.
Mental set is a preconceived notion about how to approach a problem, which is determined by a person’s experience of what has worked in the past.
The Information ProcessingApproach is computer program that was designed to simulate human problem solving.
The Tower of Hanoi problem, the operators are moving the disc to another peg.
Initialstate, conditions at the beginning of the problem.
Goal state, the solution of the problem.
The idea of operators, actions that take the problem from one state to another.
Problemspace, all possible states that could occur when solving a problem.
Meansend analysis is to reduce the difference between the initial and goal states.
Means end analysis is achieved by creating subgoals, intermediate states that are closer to the goal.
Two states of Newell and Simon’s approach by describing the Tower of Hanoi problem: initialstate and goalstate.
The MutilatedCheckerboardProblem is a checkerboard consists of 64 squares, which can be completely covered by placing 32 dominos on the board so that each domino covers two squares.
Kaplan and Simon used a technique introduced by Simon called the thinkaloudprotocol, where participants are asked to say out loud what
they are thinking while solving a problem.
Using the solution to a similar problem to guide solution of a new problem is called analogicalproblemsolving.
The contingencystrategy refers to a negotiating strategy in which a person gets what he or she wants if something else happens.
Analogicalencoding is the process by which two problems are compared and similarities between them are determined.
The tradeoffstrategy refers to a negotiating strategy in which one person says to another.
This transfer from one problem to another is called analogicaltransfer.
Targetproblem, which is the problem the participant is trying to solve.
Sourceproblem, which is another problem that shares some similarities with the target problem and that illustrates a way to solve the target problem.
Karl Duncker’s problem that has been widely used in research on analogical problem solving is the radiationproblem.
While it is difficult to apply analogies in laboratory research, people routinely use analogies in real-world settings. This is called the analogicalparadox.
The vivo problem solvingresearch involves observing people to determine how they solve problems in real-world situations.
Experts are people who, by devoting a large amount of time to learning about a field and practicing and applying that learning, have become acknowledged as being extremely knowledgeable or skilled in that particular field.
Divergentthinking is thinking that is open-ended, involving a large number of potential “solutions”.
The purpose of the groupbrainstorming technique is to encourage people to freely express ideas that might be useful in solving a particular problem.
Ronald Finke developed a technique called creativecognition to train people to think creatively.
Preinventiveforms are ideas that precede the creation of a finished creative product.
TranscranialDirectCurrentStimulation (TDCS) is a procedure for stimulating the brain in which two electrodes are placed on a person’s head.
The two electrodes in Transcranial Direct Current Simulation: cathodalelectrode and anodalelectrode.
Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain.
