Chapter 12: Problem Solving (PSY311) Flashcards
Def: Problem
an obstacle between a present state and a goal
Def: Problem solving
working around some obstacles to achieve some goal
Goal directed behavior & thoughts
Impasse to be worked around
The Gestalt approach is that success in solving issues is influenced by how it’s ___________ in our minds.
represented
Components to problem solving:
Initial state
Goal state
Subgoals
Operators
Def: Initial state
the starting point of problem solving.
Def: Goal state
End goal that you want to achieve
Def: Subgoals
Target immediate steps
Def: Operators
Rules for legal moves to intermediate states.
Def: Intermediate state
created by each action by a sequence of choices of steps.
Made by Newell & Simon
Mental Representations do what?
All possible actions, operators.
Represents obstances
Configure a reasonable method around obstacles while obeying rules & moving towards the goal.
Def: Well Defined problems
Clear initial state & goal state
Clear operators & possible moves
Def: Ill defined problems
Might have unclear initial state and/or goal state
Unclear operators or possible moves
Def: Insight
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 wasn’t initially obv.
This is a type of ill-defined problem
Def: Analytically based issues
problems solved by a process of systematic analysis, often us8ing techniques based on past experiences.
We have strategies: either rely on ______ strategies or we develop new ones
prev
Def: Fixation
our tendency to focus on a specific characteristic of the issue that keeps us from arriving at a solution.
Def: Reproductive thinking
applying successful methods to accomplish a similar task
Scaling issues (same strategy, diff operators)
Aka- reproduce what works for you
Def: Productive thinking
shift in perspective.
Requires insight
The 4-line issue requires thinking outside the box and self-imposed operators
Producing new thoughts/ideas to solve issues.
Def: Functional fixedness
Functional fixedness: focusing on familiar functions or uses of an object.
Def: Mental set
a preconceived notion abt how to approach a problem, determined by our experience of what has worked in the past
Def: Water jug problem
participants were told that their task was to figure out on paper how to obtain a required volume of water, then were given 3 empty jars.
________________ used a computer program that was made to simulate our problem solving.
This is the beginning of a research program that ________ problem solving as a process that involves search.
Newell & Simon, describes
Why is the Tower of Hanoi important?
It illustrates means-end analysis, with its setting of subgoals, this can be applied IRL.
Def: Think-aloud procedure
participants were asked to solve a problem and say out loud all of their thoughts. Determine what info one is attending to while solving an issue
Def: General Problem Solver (GPS) Theory
Model to account for problem solving processes
Looks at how do we go thru the steps of solving an issue
Requirements for General Problem Solver (GPS) Theory
Mental representation of initial and goal state
A search thru the problem space
Def: Algorithm
a set of procedures for solving a problem type
Eventually leads to a solution
Time consuming, high working memory & LTM demands
