Thinking (cognition)
mental activity that goes on in the brain when a person is organizing and attempting to understand information and communicating information to others
What does thinking include?
Memory, verbal "stream of consciousness," images and words in a person's mind
What is thinking?
It is being aware of information, making decisions on it, comparing it to other information and using it to solve problems
Mental Images
Tool used in the thinking process; mental representations that stand for objects or events and have a picture-like quality (visual image or mental picture of a word)

How do prototypes develop?
They develop according to the exposure a person has to objects in that category; also effected by cultures
What are the most typical prototypes or the least typical prototypes?
Most typical prototypes is the thinking that comes quickest to the brain; the least typical is the thinking that comes slowest; when thinking of a fruit the most would be an orange and the least would be a tomato or an olive

Who and what was the experiment done with availability heuristic and the results?
Tversky and Kahneman asked which appeared more: the letter K at the beginning or in the third letter of the word in a book; people thought the beginning of a word would contain more K but it is actually the third letter of the word
When the solution to a problem seems to come suddenly to the mind; "aha!" moment discussed by Kohler in Sultan's Chimpanzee experiment
What is thinking?
A complex process involving the use of mental imagery and various types of concepts to organize the events of daily life
What is problem solving?
A special type of thinking that involves the use of many tools, such as trial-and-error thinking, algorithms, and heuristics to solve different types of problems
Why do people have difficulties with solving problems?
Solutions to a problem remain just "out of reach" because the elements of the problem are not arranged properly or because people get stuck in certain ways of thinking that act as barriers to solving problems
Functional Fixedness
A block to problem solving that comes from thinking about an object in terms of only their typical functions; "fixed on the functions"
Example of Functional Fixedness
Looking for a screwdriver when you could use a dime because you see the dime only for its function as money

The tendency to search for evidence that fits one's beliefs while ignoring any evidence that does not fit those beliefs
Example of confirmation bias
Believers in ESP tend to remember the few studies that support it and "forget" the cases that don't
The process of solving problems by combining ideas or behavior in new ways
Convergent Thinking
Type of thinking in which a problem is seen as having only one answer, and all lines of thinking will eventually lead to that single answer, using previous knowledge and logic
Example of convergent thinking
How are a pen and pencil similar? shape and use
Divergent Thinking
Type of thinking in which a person starts from one point and comes up with many different ideas or possibilities based on that point
Which person is a creative thinker, a divergent thinker or a convergent thinker?
A divergent thinker
Example of divergent thinker
What is a pencil used for? writing, poking holes, weapon
Why are divergent thinkers able to be more creative?
Divergent thinkers make links and connections at a level of consciousness just below alert awareness, so that ideas can flow freely without being censored by the higher mental processes; they are less prone to barriers of problem solving such as functional fixedness

System of rules governing the structure and use of a language
The proportion of change in IQ within a population that is caused by hereditary factors
What do genes have to do with intelligence according to the twin studies?
The twin studies show a strong correlation between twins (about .86) but because the number isn't 1.0, intelligence has something to do with environment
Who published The Bell Curve and what did it claim? why was it proved wrong?
Herrnstein and Murray published the book; it claims that IQ is inherited; this is proved wrong because compared race to intelligence by IQ, they assumed that intelligence was influenced by genetics, they failed to understand that heritability only applies to differences within a group of people

What changes in children as they get older with the relation to language?
Collective monologue
What did Piaget theorize about language?
Piaget theorized that concepts preceded and aided the development of language; concepts become the "pegs" upon which words are "hung"
Idea of Piaget's theory
Children have the concept for "mother" before being able to say "mama"
What did Vygotsky theorize about language?
Vygotsky theorized that language actually helped develop concepts and that language could help the child learn to control behavior (social behavior)
Idea of Vygotsky's theory
"mama" was learned and then the elements of "mama-ness" - warm, soft, food, safety, and etc - could develop around that word

Language can shape our thoughts about space, time, color, and objects; this idea is supported and also critiqued
What can language influence?
Language can influence the perception of others ("computer geek" vs. "software engineer"); also influences problem solving, cognition, and memory
What did animal studies determine about language?
Animals can communicate (warning growl of an angry dog), use of language is still unsure because gestures are instinctive, there have been attempts for primates and dolphins to use sign language, but there is no conclusive evidence of syntax mastery
What did Kanzi the chimpanzee achieve with language?
