Chapter 8: What is Cognition?
The mental processes involved in acquiring knowledge. (Your brain’s ability to learn)
In 1978 Jim Greeno proposed that there are 3 basic types of problems:
Problems of Inducing Structure, Problems of Arrangement, Problems of Transformation
Problems of Inducing Structure
Where people are required to discover relations among numbers, words, symbols, or ideas. (Example: Sudoku Game)
Problems of Arrangement
Where people arrange the parts of a problem in a way that satisfies some criterion.
Problems of Transformation
Involve carrying out a SEQUENCE of transformations in order to reach a specific goal. (Example: Baking Cookies)
Irrelevant Information
people try and figure out how to use all the information before figuring out if it is even relevant
Functional Fixedness
the tendency to perceive an item only in terms of its most common use. (Assuming unnecessary constraints)
Mental Set
when people persist in using problem-solving strategies that have worked in the past.
Trial & Error
trying possible solutions sequentially and discarding those that are in error until one works. (Child doing shapes order)
Algorithm
a methodical, step-by-step procedure for trying all possible alternatives in searching for a solution to a problem, which guarantees a solution. (Rubik’s cube)
Heuristic
guiding principles or “rules of thumb” used in solving problems-they don’t guarantee success. (I before E except after C)
Sub-Goal
allows one to solve part of the problem, therefore moving toward success. (Reordering Rings example)
The Representativeness Heuristic
involves basing the estimated probability of an event on how similar it is to the typical prototype of that event. (The chance of getting heads or tails on a coin when flipping it.)
The Gambler’s Fallacy
is the belief that the odds of a chance event increase if the event hasn’t occurred recently. (example: A slot machine)
Alfred Binet and Theodore Simon…
developed and published the first IQ test in 1905.
The Intelligence Quotient (Formula)
MA/CA * 100= IQ MA= mental age CA= chronological age
David Wechsler…
the first to devise an instrument to measure intelligence in adults. He later devised downward extensions of his scale for children. Wechsler is credited with two innovations in intelligence testing.
For most IQ tests, the mean is set to ____ and the standard deviation is set to ____
100 and 15
Reliability
The measurement consistency of a test. Ex- IQ tests don’t indicate your academic achievements, they are measuring your intelligence.
Validity
The ability of a test to measure what it’s designed to measure. (Is it measuring what it’s supposed to measure?)
The Flynn Effect
the trend, all over the developed world, for IQ scores to increase from one generation to the next.
Robert Sternberg….?
Howard Gardener…?
The creator of Triarchic Theory of Intelligence.
he argues that IQ tests emphasize verbal and mathematical skills and exclude other important skills
Phonology
is the most basic units of speech. (EC: T says tuh)
Morphology
is taking the basic units of speech into meaning in a language, consisting of root words, prefixes, and suffixes (EC: T combined with oy gives toy)
