Chapter 8 Flashcards
Study the way in which information is processed and manipulated in remembering, thinking, and knowing. It is a broad field that includes:
-the study of consciousness
-memory, and
-cognitive neuroscience
Cognitive Psychologist
A label for approaches that sought to explain observable behavior by investigating mental processes and structures that cannot be observed directly.
Cognitive Psychology
3 basic processes that compare the computer to the human mind
Input, storage, and retrieval
Computers receive information that has already been ______ removing most ________.
Coded
Ambiguity
In humans, ambiguous information enters through
Sensory receptors
Computers can do some things better than ______. They can perform complex _________ ____________ much faster and more accurately.
Humans
Numerical Calculations
Computers are quite limited in their ability to
Learn, to change, and generalize.
Is the process of manipulating information mentally by forming concepts, solving problems, making decisions, and reflecting in a critical or creative manner.
Thinking
What forms of thinking involves the manipulation of information that is inferred from our behavior?
Images and Concepts
A mental category that is used to group objects, events, and characteristics.
Concepts
Which classifications are used for a concept?
Objects, relations, events, abstractions, and qualities.
What are the 4 important reasons for Concepts?
- They allow us to generalize. Concepts allow us to navigate the world by generalizing our experiences across members of a category.
- They allow us to associate experiences and objects.
- They aid memory by making it more efficient so that we do not have to reinvent the wheel each time we come across a piece of information.
- They provide clues about how to react to a particular object or experience.
Is a model emphasizing that when people evaluate whether a given item reflects a certain concept, they compare the item with the most typical item(s) in that category and look for a “family resemblance” with that item’s properties.
Prototype model
What are the 4 steps in problem solving?
- Find and Frame Problems
- Develop Good Problem-Solving Strategies
- Evaluate Solutions
- Rethink and Redefine Problems and Solutions over Time
The first step in the process is to recognize that you have a problem.
Find and Frame Problems
Once you know what the problem and clearly define it we can develop strategies to solve it.
Develop Good Problem-Solving Strategies
Once we have solved a problem, an evaluation of how effective our solution is needed.
Evaluate Solutions
The final step in problem-solving is to rethink and redefine problems continually.
Rethink and Redefine Problems and Solutions over Time
Three effective strategies of developing good problem-solving strategies
- Sub-goals
- Algorithms
- Heuristics
Intermediate goals or intermediate problems that put us in a better position for reaching the final goal or solution.
Sub-goals
These are strategies that guarantee a solution to a problem. Can come as formulas, instructions, and the testing of all possible solutions.
Algorithms
These are shortcut strategies or guidelines that suggest a solution to a problem but do not guarantee a answer.
Heuristics
Are beliefs that interfere with objectivity.
Biases
Two types of biases
- Confirmation Bias
- Hindsight Bias
Is the tendency to search for an use information that supports our ideas rather than refutes them. Our decisions can also become further biased because we tend to seek out and listen to people who views confirm our own while we avoid those dissenting views.
Confirmation Bias
Is our tendency to report falsely, after the fact, that we accurately predicted an outcome; sometimes referred to as “I knew it all along effect.”
Hindsight Bias
Decision-making strategies that involve educated guesses or rules of thumb. Intuitive and efficient ways of solving problems and making decisions; they are often at work when we a decision by following a gut feeling.
Heuristics
Two types of Heuristics
- Availability Heuristic
- Representative Heuristic
