a problem consisting of original state, goal state, and rules are clearly specified
|
WELL-STRUCTURED PROBLEMS
|
|
original state, goal state, or the rules are unclear.
|
ILL-STRUCTURED PROBLEMS
|
|
solving a previous problem increase the difficulty of solving a problem later.
|
NEGATIVE TRANSFER
|
|
solving a previous problem facilitates solving a problem later
|
POSITIVE TRANSFER
|
|
an effort to overcome obstacles obstructing the path to a solution
|
Problem solving
|
|
rules of thumb that often lead to correct conclusions
|
Heuristics
|
|
is a method that will always produce a solution to the problem, sooner or later (if it exists). Ie, trying every possible combination until the correct one is reached.
|
algorithms
|
|
move outward from the problem in a variety of directions...score high on creativity tests
|
Divergent thinking
|
|
Working towards a single, specific answer
|
Convergent thinking
|
|
All possible actions that can be attempted to solve a problem.
|
Problem space
|
|
one way of trying to reduce negative transfer is to set the problem aside
|
Incubation
|
|
(Entrenchment):keep trying the same solution they have used in previous problems.
|
Mental set
|
|
The function or use we assign to objects tends to remain fixed or stable
|
Fixation
|
|
belief concerning uniformity of particular characteristics
|
Stereotypes
|
|
the inability to realize that something known to have a particular use may also be used for performing other functions
|
Functional fixedness
|
|
reasoning involves reaching a conclusion based upon assumptions that are known to be true.
|
Deductive Reasoning
|
|
something is LIKELY TO BE TRUE on the basis of past experience, no guarantee that it will be absolutely true.
- Reasoning from specific facts to reach a conclusion that may explain the facts |
Inductive Reasoning
|
|
The premises of this state something about the category memberships f the terms. Ie, All cognitive psychs are pianists, all pianist are athletes, therefore, all cognitive psychs are atheletes.
|
Categorical Syllogism
|
|
people seem to use similarity to some prototypical example rather than probability as the basis for judgment.
|
Conjunction fallacy
|
|
weighting of utility based on the individual not objective criteria.
|
Subjective Utility
|
|
goal of human action is to seek pleasure and avoid pain
|
Subjective expected utility theory
|
|
A strategy for reducting a wealth of information built on bounded rationality and involves picking criteria that is important.
|
Elimination by aspects
|
|
consider options one at a time and select one as soon as we find one that is satisfactory (meets minimum level of acceptability)
- People do not have unlimited rationality as suggest by previous theories, but not rational. |
Satisficing
|
|
“the way options are presented influence the selection.”
|
Framing Effects
|
|
When use of previous experience can not help us to deduce what might be true; context may activate an appropriate schema.
|
PRAGMATIC REASONING SCHEMAS
|
|
-Judgment on basis of what is readily brought to mind
-Underestimate a LIKELY EVENT if it never occurred before Ie, it is easy to remember disasters rather than deaths by nat. causes. |
AVAILABILITY HEURISTIC
|
|
Start with a first guess and then we make adjustments to that number on the basis of additional information.
|
ADJUSTMENT FROM AN ANCHOR HEURISTIC
|
|
(creeping determinism): Overconfidence about events that have already happened.
|
Hindsight Bias
|
|
Sternberg process of complex task involving encoding the problem and formulating a general strategy for attacking the problem(s)
-done more by people with high IQ |
Global planning
|
|
Sternberg process of complex task involving forming and implementing strategies for details of the task
-Done more by people with low IQ. |
Local planning
|
|
In order to understand intelligence, we need to take a look at the context in which it occurs.
-Different Cultures and experience affect what we know. |
Contextualists
|
|
a test that would be fair regardless of culture
|
Cultural Fair testing
|
|
devising a test that is relevant to a specific culture assessing the appropriate skills and knowledge
|
Culture Relevant tests
|
|
a process of intelligence time theory in which the speed of gaining access to the long-term memory is assessed.
|
Lexical Access (Hunt)
|
|
a process of intelligence time theory which tests the time it take to select from among several possibilities.
|
Choice Reaction Time (Jenson)
|
|
Localized metabolism of glucose.
|
neural efficiency
|
|
3 level IQ test, testing: Crystalized, Fluid-Analytic, and Short Term Memory
