a deficiency of the brain chemical orexin.

Someone who stays in a cave with no light alternates between sleepiness and wakefulness on about a 24 hour cycle. Why?

During REM sleep,

dreaming is likely to occur.

east

eleven letters

During reading, the eyes alternate between fixations and saccades. Reading--in the sense of understanding the words--occurs during

fixations only.

Fox and Crow are both thirsty. They come upon a large crock with some water in it, but cannot lift the pitcher or reach down to the water. There happens to be a bucket of baseballs nearby and Fox steps back to throw the baseballs to try to break the crock. Crow reminds him that this will only spill the water, and uses the more clever solution of dropping the baseballs into the crock to raise the water level to within reach. Fox's problem was

functional fixedness.

Compared with normal readers, speed readers

have briefer fixations.

The availability heuristic is based on the assumption that

if we can easily remember examples of something, it must be a common event.

What are algorithms?

mechanical, repetitive mathematical procedures for solving a problem

Each unit of meaning in a word is called a

morpheme

For most people, REM sleep occurs

mostly toward the end of the night's sleep.

When 2- to 3-year-old children speak, they

overgeneralize grammatical rules.

The "word superiority effect" is the observation that on the average,

people recognize a letter within a familiar word more easily than a letter by itself.

Each letter or short combination of letters in a language that forms a unit of sound is known as a

phoneme

For thinking and problem solving, we use System 1 for _____ and we use System 2 for _____.

quick automatic processes... slow processes that require attention

When chess experts were shown a chess board and asked to recall the pieces, they

remembered better than novices if the pieces were arranged as in a game, but about the same if they were arranged randomly.

The tendency to assume that if an item is similar to members of a particular category, it is probably a member of that category itself, is known as the

representativeness heuristic.

In decision making, searching until you find something that is good enough is called

satisficing

What is typical for the language of a one-year-old?

some language comprehension, but not much production

Who would be LEAST likely to show the word-superiority effect?

someone who is just learning how to read

The brain activity associated with REM sleep is most similar to that associated with

stage 1 sleep.

What is meant by the "productivity" of human language?

the ability to create new sentences

the full word "legislatures"

the person has been asleep less than an hour.

What is meant by "parentese?"

the way parents simplify their speech to help infants learn language

The system for converting a deep structure into a surface structure in language is called

transformational grammar.

Common chimpanzees that learned to communicate by sign language or visual symbols

use their symbols almost exclusively to make requests.

In an experiment a cough or a tone replaced the first "s" in the word "legislatures" in a sentence the subjects were listening to. The results of this experiment support the idea that

we hear words as a whole, rather than a group of separate sounds (letters).

In which situation would a heuristic be most useful?

you have too many hypotheses to test
