Cognitive Psychology - Problem Solving & Creativity Flashcards
an obstacle between a present state and a goal and it is not immediately obvious how to get around the obstacle
problem
Problem solving, for the ________, 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.
Gestalt
the process of changing a problems representation
restructuring
a problem, as defined by psychologists is a situation in which you need to accomplish a _________ and the _________ is not immediately obvious
- goal
- solution
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
insight
how a problem is represented in the mind depends on how the problem is _________
presented
according to Gestalt, solving the solution is obtained first by _________ the problem and then _________ it in different ways
- perceiving
- representing
each ways about going about solving a problem involves a different way of _________ it in the mind
representing
‘reorganisation of a person’s mental representations’ in the definition of insight, corresponds to what according to Gestalts approach
restructuring
________ in the definition of insight corresponds to the Gestalt emphasis on suddenly realizing the problem’s solution
sudden comprehension
Metcalf and Wiebe designed an experiment to distinguish between ______ problems and _______ problems
- insight
- noninsight
For noninsight problems, Metcalfe and Wiebe used algebra problems which are also called ______ problems
analytically based
Metcalf and Wiebe demonstrated that solutions for problems that have been called insight problems _______
occur suddenly
people’s tendency to focus on a specific characteristic of the problem that keeps them from arriving at a solution.
fixation
problems that are solved by a process of systematic analysis, often using techniques based on past experience.
analytically based problems
an effect that occurs when the idea a person has about an objects function inhibits the persons ability to use the object for different functions
functional fixedness
To solve this problem, participants needed to tie the pliers to one of the strings to create a pendulum, which could then be swung to within the person’s reach.
two string problem
The solution to this problem occurs when the person realizes that the matchbox can be used as a support rather than as a container
candle problem
a preconceived notion about how to approach a problem, which is determined by a person’s experience of what has worked in the past
mental set
A problem, first described by Luchins, that illustrates how mental set can influence the strategies that people use to solve a problem
water jug problem
Newell and Simon (1972) saw problems in terms of an _______ state—conditions at the beginning of the problem—and a ______ state—the solution of the problem.
- initial state
- goal state
Newell and Simon also introduced the idea of _______—actions that take the problem from one state to another and are goverend by rules
operators
Conditions after each step is made toward solving a problem
intermediate state
All possible states that could occur when solving a problem
problem space
A way of solving a problem in which the goal is to reduce the distance between the initial and goal state
means end analysis
Small goals that help create intermediate states that are closer to
the goal. Occasionally, may appear to increase the distance to the goal state, but in the long run can result in the shortest path to the goal.
subgoals
from the Tower of Hanoi, what is this an example of ?
Small goals that help create intermediate states that are closer to
the goal. Occasionally, a subgoal may appear to increase the distance to the goal state, but in the long run can result in the shortest path to the goal.
subgoals
from the Tower of Hanoi, what is this an example of ?
Rule: A larger disc can’t be placed on a smaller one.
operators
from the Tower of Hanoi, what is this an example of ?
Establish subgoals, each of which moves the solution closer to the goal state.
means end analysis
from the Tower of Hanoi, what is this an example of ?
Subgoal 4: To free up the medium-sized disc, you need to move the small disc from the middle peg back to the peg on the left
subgoals
According to Newell and Simon, the person has to search the problem space to find a solution, and they proposed that one way to direct the search is to use a strategy called ________
means end analysis
Our overall goal in applying _________ to the Tower of Hanoi problem is to reduce the size of the difference between initial and goal states.
means end analysis
The primary goal of means–end analysis is to reduce the difference between the initial and goal states. This is achieved by creating _________—intermediate states that are closer to the goal.
subgoals
procedure where participants are asked to say out loud what they are thinking while solving a problem. They are instructed not to describe what they are doing, but to verbalize new thoughts as they occur.
think aloud protocol
One goal of a think-aloud protocol is to determine what information the person is ______ while solving a problem.
attending to
using the solution to a similar problem to guide solution of a new problem often using techniques based on past experiences
analogical problem solving
making a comparison in order to show similarity between two different things
analogy
Transferring experience in solving one problem to the solution of another, similar problem
analytical transfer
